From 55687d3c461f4a3a203d6c1240c99564d09d9047 Mon Sep 17 00:00:00 2001 From: Todd Baur Date: Wed, 6 May 2026 16:43:55 -0700 Subject: [PATCH 01/43] docs(graphify): add comprehensive knowledge graph analysis MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extract and visualize complete PAP codebase architecture as navigable knowledge graph. Key outputs: - graph.html: Interactive visualization (vis.js) with 99.3% connectivity - GRAPH_REPORT.md: Deep architectural analysis with 5-layer spine - .graphify_extract.json: Full graph data (141 nodes, 190 edges, 22 hyperedges) - .graphify_communities.json: 10 communities via Louvain clustering - .graphify_labels.json: Semantic community labels Analysis reveals: - Protocol-first design with Mandate/Session/Receipt core - Two-boundary security model (SD-JWT + OS sandbox) - Schema.org vocabulary driving UI rendering - Multi-language bindings (C, C++, C#, Java, Python, TypeScript) - Federation-ready architecture with Chrysalis registry 99.3% connectivity achieved through strategic bridge discovery across: - Docs ↔ implementation - FFI ↔ core protocol - UI ↔ orchestrator - Tests ↔ runtime Extraction cost: 558,894 input / 68,938 output tokens Co-Authored-By: Claude Sonnet 4.5 --- graphify-out/.graphify_communities.json | 1 + graphify-out/.graphify_cost.json | 14 +

WebSocket and OHTTP are transport layers that carry PAP sessions, not define them. Changes: - Moved SixPhaseHandshake from transport to protocol layer - Removed from TransportAbstraction hyperedge - Added Session -> SixPhaseHandshake (protocol implements handshake) - Added WebSocketTransport -> Session (transport carries protocol) - Added OHTTPRelay -> Session (alternative transport) - Updated report to emphasize transport-agnostic design The graph now correctly shows PAP as protocol-first with pluggable transport implementations.

Created `ApprovalToastStack` component that renders fixed bottom-right toast notifications for approval requests. Toasts read from `canvas_state.hitl_pending` and provide two interaction modes: - **Zero-disclosure agents**: Quick APPROVE button for instant approval - **Multi-property disclosure**: VIEW DETAILS button opens workflow panel Key features: - Slide-in animation from bottom (250ms ease-out) - Dismiss button (×) clears pending request - Risk level badges (HIGH/CRITICAL) styled with semantic colors - Humanized action display (strips "schema:" and "Action" suffix) - Full unit test coverage for humanize_action logic Styling follows established patterns from workflow panel (z-index 2000, uses design system colors and spacing).

+todd@baursoftware.com +
 +Internet + + +This document specifies the Principal Agent Protocol (PAP), a +cryptographic protocol for human-controlled agent-to-agent +transactions. PAP establishes a trust model rooted in human +principals, defines hierarchical delegation through signed mandates, +enforces context minimization through selective disclosure at the +protocol level, and provides session ephemerality as a structural +guarantee. The protocol uses no novel cryptographic primitives and +requires no central registry, token economy, or trusted third party. + + +
Introduction + +
Problem Statement +Existing agent-to-agent protocols authenticate agents as platform +entities, not as delegates of human principals. None enforce context +minimization at the protocol level. Disclosure is +implementation-dependent. Session ephemerality is undefined. Execution +isolation is absent--agents run in the same address space as the +orchestrator or other services, creating blast radius problems even +when disclosure is minimized. Economic models underneath these +protocols are compatible with platform capture through cloud compute +metering. +
+ +
Design Goals +PAP is designed to satisfy the following goals: + +
    +
  1. The human principal is the root of trust for every transaction.
    2. +
  2. Context disclosure is enforced by the protocol at the request boundary (via SD-JWT).
    3. +
  3. Execution is isolated at the process boundary via OS-level capabilities.
    4. +
  4. Sessions are ephemeral by design; no persistent correlation.
    5. +
  5. Delegation is hierarchical with cryptographically enforced bounds.
    6. +
  6. Co-signed receipts prove both disclosure scope and execution constraints.
    7. +
  7. No novel cryptography, no token economy, no central registry.
    8. +
  8. Any compliant implementation MUST be buildable from this document +alone, without reference to a specific programming language.
    9. +
+
+ +
Protocol Overview +A PAP transaction involves: + +
    +
  • A human principal who holds a device-bound keypair.
    • +
  • An orchestrator agent operating under a root mandate.
    • +
  • One or more downstream agents operating under delegated mandates, each executing in sandboxed isolation.
    • +
  • A marketplace for agent discovery and disclosure filtering.
    • +
  • A 6-phase session handshake between pairs of agents.
    • +
  • Request boundary security via SD-JWT selective disclosure (minimize what the agent sees).
    • +
  • Execution boundary security via OS sandboxing (minimize what the agent can do).
    • +
  • Co-signed receipts recording property references and enforcement proof, never values.
    • +
+
+
+ +
Conventions and Terminology +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", +"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", +and "OPTIONAL" in this document are to be interpreted as described +in BCP 14 [RFC 2119] [RFC 8174] when, and only when, they appear +in all capitals, as shown here. + +
Definitions +Principal: A human user who holds the root keypair and is the +ultimate authority over all agent actions taken on their behalf. +Orchestrator: An agent that holds the root mandate from the +principal. The orchestrator is the only agent that MAY hold the +principal's full context. It delegates scoped mandates to downstream +agents. +Mandate: A signed authorization object that specifies what an +agent is permitted to do, what context it may disclose, and when +the authorization expires. +Mandate Chain: An ordered sequence of mandates from root to +leaf, each cryptographically linked to its parent. +Scope: The set of actions a mandate permits. Deny-by-default: +an empty scope permits nothing. +Disclosure Set: The set of context classes an agent holds and +the conditions under which they may be shared. +Capability Token: A single-use, signed authorization to open a +session with a specific agent for a specific action. +Session DID: An ephemeral did:key identifier generated for a +single session and discarded at session close. +Receipt: A co-signed record of a transaction that contains +property type references but never property values. +Decay State: The lifecycle state of a mandate as it approaches +or passes its TTL without renewal. +
+
+ +
Trust Model and Threat Model + +
Trust Hierarchy +The PAP trust hierarchy is: + +Human Principal (device-bound keypair, root of trust) + +-- Orchestrator Agent (root mandate, full principal context) + +-- Downstream Agent (task mandate, scoped context) + +-- Marketplace Agent (own principal chain) + +The principal's device-bound keypair is the sole root of trust. +Every agent in a transaction MUST carry a cryptographically +verifiable mandate chain traceable to this root. +
+ +
Trust Assumptions + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
AssumptionVerification Method
Principal keypair not compromisedWebAuthn device binding (Section 4.3)
Orchestrator delegates correctlyMandate chain verification (Section 5.6)
Session keys not leakedSingle-use per session, discarded at close
Clocks approximately synchronizedRFC 3339 timestamps; receivers SHOULD reject tokens with skew exceeding implementation-defined thresholds
Ed25519 not brokenCryptographic library security; algorithm agility reserved for future versions
+ +
Threat Model +PAP is designed to defend against the following threats: +T1. Context profiling. An adversary correlates a principal's +transactions across sessions to build a behavioral profile. +Mitigation: Ephemeral session DIDs (Section 6.3) ensure each +session is cryptographically unlinkable. +T2. Over-disclosure. An agent discloses more principal context +than the principal authorized. Mitigation: SD-JWT selective +disclosure (Section 7) structurally prevents disclosure of claims +not included in the disclosure set. Marketplace filtering +(Section 9.3) excludes agents whose requirements exceed the +mandate before any session is established. +T3. Delegation bypass. A downstream agent acts outside its +delegated scope. Mitigation: Scope containment (Section 5.4) and +TTL bounds (Section 5.5) are verified cryptographically at each +level of the mandate chain. +T4. Replay attacks. An adversary replays a captured capability +token to open an unauthorized session. Mitigation: Nonce +consumption (Section 6.2) ensures each token is single-use. +T5. Mandate tampering. An adversary modifies a mandate in the +chain. Mitigation: Parent hash binding (Section 5.3) and Ed25519 +signatures (Section 5.2) detect any modification. +T6. Platform capture. A platform operator accumulates control +over agent transactions through infrastructure dependency. +Mitigation: Federated discovery (Section 10), no central +registry, no token economy, principal-held keys. Marketplace +registries MUST NOT rank query results by operator metrics +(Section 9.6) -- ranking power is platform capture power. Trust +evaluation is the principal's responsibility. +T7. Payment linkability. A payment is correlated with the +principal's identity. Mitigation: Chaumian ecash blind-signed +tokens (Section 13.1) provide unlinkable proof of value transfer. +
+ +
Explicit Non-Goals +The following are explicitly out of scope for PAP: + +
    +
  1. Compatibility with token economy monetization.
    2. +
  2. Enclave-as-equivalent-to-local trust models.
    3. +
  3. Identity recovery through platform operators.
    4. +
  4. Central registries for agent discovery.
    5. +
  5. Runtime scope expansion of mandates.
    6. +
  6. Arbitrary code execution in the orchestrator context.
    7. +
  7. Any extension that trades trust guarantees for adoption ease.
    8. +
+
+
+ +
Identity Layer + +
DID Method +PAP uses the did:key method as defined in [DID-KEY]. All +identifiers MUST use Ed25519 public keys with the following +derivation: + +did:key:z<base58btc(0xed01 || public_key_bytes)> + +Where: +- 0xed01 is the multicodec prefix for Ed25519 public keys. +- public_key_bytes is the 32-byte Ed25519 public key. +- base58btc is Bitcoin's base58 encoding. +- The z prefix indicates base58btc multibase encoding. +Implementations MUST support did:key resolution by extracting +the public key bytes from the DID string: + +
    +
  1. Strip the did:key:z prefix.
    2. +
  2. Base58-decode the remainder.
    3. +
  3. Verify the first two bytes are 0xed and 0x01.
    4. +
  4. The remaining 32 bytes are the Ed25519 public key.
    5. +
+
+ +
DID Document +A DID document for a PAP identity MUST conform to [DID-CORE] and +contain: + +{ + "@context": "https://www.w3.org/ns/did/v1", + "id": "did:key:z...", + "verificationMethod": [{ + "id": "did:key:z...#key-1", + "type": "Ed25519VerificationKey2020", + "controller": "did:key:z...", + "publicKeyMultibase": "z<base58btc(0xed01 ++ public_key_bytes)>" + }], + "authentication": ["did:key:z...#key-1"] +} + +A DID document MUST NOT contain any personal information. It +contains only the public key and verification method reference. +
+ +
Principal Keypair +The principal keypair is the root of trust. It MUST be an Ed25519 +keypair. In production deployments, the private key SHOULD be +bound to a hardware authenticator via WebAuthn [WEBAUTHN]. +Implementations MUST support the PrincipalSigner interface: + +
    +
  • did() -> String -- The did:key identifier.
    • +
  • sign(message: bytes) -> bytes -- Ed25519 signature (64 bytes).
    • +
  • verifying_key() -> Ed25519PublicKey -- The public key.
    • +
+Implementations MAY use software keys for development and testing. +Production deployments SHOULD use WebAuthn-backed keys. +
+ +
Session Keypair +A session keypair is an ephemeral Ed25519 keypair generated fresh +for each protocol session. Session keypairs: + +
    +
  • MUST be generated using a cryptographically secure random number +generator.
    • +
  • MUST NOT be derived from or linked to the principal keypair.
    • +
  • MUST be discarded when the session closes.
    • +
  • MUST NOT be persisted to stable storage.
    • +
+The session DID is derived using the same did:key method as the +principal DID. An observer MUST NOT be able to determine whether a +did:key identifier represents a principal or a session key. +
+
+ +
Mandate Structure and Delegation Rules + +
Mandate Object +A mandate is the core delegation primitive. It authorizes an agent +to perform specific actions with specific context. A mandate MUST +contain the following fields: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
principal_didStringREQUIREDDID of the human principal (root of trust)

signatureString or nullOPTIONALEd25519 signature (base64url-no-pad)
+ +
Mandate Signing +A mandate MUST be signed by the issuer's Ed25519 signing key. +The canonical form for signing MUST be computed as follows: + +
    +
  1. Construct a JSON object containing all mandate fields EXCEPT +signature.
    2. +
  2. DateTime fields MUST be serialized as RFC 3339 strings.
    3. +
  3. Null fields MUST be included as JSON null.
    4. +
  4. Serialize the JSON object to bytes.
    5. +
  5. Compute the Ed25519 signature over these bytes.
    6. +
  6. Encode the 64-byte signature using base64url without padding +(RFC 4648 Section 5, no = padding).
    7. +
+The canonical JSON object MUST contain exactly these keys: + +{ + "principal_did": "...", + "agent_did": "...", + "issuer_did": "...", + "parent_mandate_hash": null, + "scope": { ... }, + "disclosure_set": { ... }, + "ttl": "2026-03-15T20:00:00+00:00", + "issued_at": "2026-03-15T16:00:00+00:00", + "payment_proof": null +} + +
+ +
Mandate Hashing +The mandate hash is used for parent-child linking in delegation +chains. It MUST be computed as: + +
    +
  1. Compute the canonical form (Section 5.2, step 1-4).
    2. +
  2. Apply SHA-256 to the canonical bytes.
    3. +
  3. Encode the 32-byte digest using base64url without padding.
    4. +
+The hash MUST be deterministic: the same mandate MUST always +produce the same hash. +
+ +
Scope + +
5.4.1. Scope Object +A scope defines the set of permitted actions. It is deny-by-default: +an agent with an empty scope MUST NOT perform any action. + +{ + "actions": [ + { + "action": "schema:SearchAction", + "object": "schema:WebPage", + "conditions": {} + } + ] +} + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
actionsArray of ScopeActionREQUIREDThe permitted actions
+ +
5.4.2. ScopeAction Object + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
actionStringREQUIREDSchema.org action type (e.g., schema:SearchAction)
objectString or nullOPTIONALSchema.org object type constraint (e.g., schema:Flight)
conditionsObjectOPTIONALProtocol-level conditions (key-value pairs). Default: empty object.
Action and object type references MUST use the schema: prefix +for Schema.org vocabulary. Implementations MAY define additional +namespaced prefixes for domain-specific vocabularies. +
+ +
5.4.3. DisclosureSet Object +The disclosure set defines what context an agent holds and the +conditions for sharing it. + +{ + "entries": [ + { + "type": "schema:Person", + "permitted_properties": ["schema:name", "schema:nationality"], + "prohibited_properties": ["schema:email", "schema:telephone"], + "session_only": true, + "no_retention": true + } + ] +} + + + + + + + + + + + + + + + + + + + +

+ +
5.4.4. DisclosureEntry Object + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
typeStringREQUIREDSchema.org type (e.g., schema:Person)
permitted_propertiesArray of StringREQUIREDProperties the agent MAY disclose
prohibited_propertiesArray of StringREQUIREDProperties the agent MUST NOT disclose
session_onlyBooleanOPTIONALIf true, disclosed data is valid only for the session duration. Default: false.
no_retentionBooleanOPTIONALIf true, the receiving party MUST NOT retain disclosed data beyond the session. Default: false.
Property references MUST use Schema.org property names with the +schema: prefix. +Property Reference Format: When used in receipts or marketplace +advertisements, a fully qualified property reference is formed as +{type}.{property}, e.g., schema:Person.schema:name. +
+ +
5.4.4.1. TEE Requirement for No-Retention Disclosures +When a disclosure entry has no_retention set to true, the receiving +agent MUST provide TEE attestation (Section 13.6) during session +establishment. If the receiving agent cannot provide valid TEE +attestation, the initiating agent MUST NOT disclose properties from +that entry. +Without TEE attestation, no_retention is a contractual constraint +only -- the protocol cannot enforce data deletion on an untrusted host. +Implementations SHOULD clearly communicate this limitation to +principals when TEE attestation is unavailable. +An implementation's disclosure validation MUST return one of three +states to the caller: + + + + + + + + + + + + + + + + + + + + + + + + +
StateMeaning
NotRequiredNo no_retention entries in the disclosure set
TeeEnforcedTEE attestation present; retention constraint is cryptographic
ContractualOnlyNo TEE available; no_retention is a contractual term only
Implementations that support the TEE extension (Section 13.6) MUST +treat ContractualOnly as an error. Implementations without TEE +support MAY proceed with ContractualOnly but MUST expose this +state to the caller so the principal can make an informed decision. +
+ +
5.4.5. Scope Containment +A child scope S_c is contained by a parent scope S_p (written +S_c <= S_p) if and only if for every action A_c in S_c, there +exists an action A_p in S_p such that: + +
    +
  1. A_c.action == A_p.action
    2. +
  2. If A_p.object is non-null, then A_c.object MUST equal +A_p.object.
    3. +
  3. If A_p.object is null, then A_c.object MAY be any value +(including null).
    4. +
  4. If A_p.object is non-null and A_c.object is null, the +containment check MUST fail. A child MUST NOT broaden an object +constraint.
    5. +
+
+
+ +
Delegation Rules +When an agent delegates a mandate to a child agent, the following +rules MUST be enforced: +R1. Scope Containment: The child mandate's scope MUST be +contained by the parent mandate's scope (Section 5.4.5). If +scope containment fails, the delegation MUST be rejected. +R2. TTL Bound: The child mandate's ttl MUST NOT exceed the +parent mandate's ttl. If the child TTL exceeds the parent TTL, +the delegation MUST be rejected. +R3. Parent Hash Binding: The child mandate's +parent_mandate_hash MUST equal the hash (Section 5.3) of the +parent mandate's canonical form. +R4. Issuer Chain: The child mandate's issuer_did MUST equal +the parent mandate's agent_did. The child mandate MUST be signed +by the parent mandate's agent_did key. +R5. Principal Propagation: The child mandate's principal_did +MUST equal the parent mandate's principal_did. +R6. Root Mandate: A root mandate MUST have +parent_mandate_hash set to null. A root mandate's issuer_did +MUST equal its principal_did. +
+ +
Mandate Chain Verification +A mandate chain is an ordered array of mandates [M_0, M_1, ..., M_n] +where M_0 is the root mandate. Verification MUST proceed as follows: + +
    +
  1. M_0.parent_mandate_hash MUST be null.
    2. +
  2. M_0.signature MUST verify against the principal's public key.
    3. +
  3. For each i from 1 to n: +a. M_i.parent_mandate_hash MUST equal hash(M_{i-1}). +b. M_i.scope MUST satisfy scope containment against + M_{i-1}.scope (Section 5.4.5). +c. M_i.ttl MUST NOT exceed M_{i-1}.ttl. +d. M_i.signature MUST verify against the public key of + M_{i-1}.agent_did.
    4. +
+If any check fails, the entire chain MUST be rejected. +
+ +
Decay State Machine +A mandate's decay state tracks its lifecycle as the TTL progresses. +The decay state MUST be one of: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
StateDescription
ActiveFull scope, within TTL
DegradedReduced scope, TTL within decay window, renewal pending
ReadOnlyNo execution permitted, observation only, TTL expired
SuspendedNo activity, awaiting principal review
+
5.7.1. State Transitions +The following transitions are valid: + +Active --> Degraded --> ReadOnly --> Suspended + ^ | | + | | | + +-- renewal -+-- renewal -+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

DegradedReadOnlyTTL expired without renewal
ReadOnlySuspendedImplementation-defined timeout without principal action
DegradedActiveMandate renewed by issuer
ReadOnlyActiveMandate renewed by issuer
Suspended(none)Suspended mandates MUST NOT be renewed. Principal MUST issue a new mandate.
Any transition not listed above MUST be rejected. +
+ +
5.7.2. Decay Computation +An implementation SHOULD compute the current decay state as: + +function compute_decay_state(mandate, decay_window_seconds): + now = current_utc_time() + if now > mandate.ttl: + if mandate.decay_state == Suspended: + return Suspended + else: + return ReadOnly + else: + remaining = mandate.ttl - now (in seconds) + if remaining <= decay_window_seconds: + return Degraded + else: + return Active + +The decay_window_seconds parameter is implementation-defined. +Implementations SHOULD document their chosen value. +
+
+
+ +
Session Lifecycle + +
Session State Machine +A session tracks the state of a transaction between two agents. +The session state MUST be one of: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
StateDescription
InitiatedCapability token presented, awaiting verification

+ +
Capability Token +A capability token is a single-use authorization to open a session. +It MUST contain the following fields: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

6.2.1. Token Signing +The token canonical form MUST be: + +{ + "id": "...", + "target_did": "...", + "action": "...", + "nonce": "...", + "issuer_did": "...", + "issued_at": "...", + "expires_at": "..." +} + +Signing follows the same procedure as mandate signing (Section 5.2). +
+ +
6.2.2. Token Verification +A receiving agent MUST verify a capability token as follows: + +
    +
  1. token.target_did MUST match the receiver's DID.
    2. +
  2. token.nonce MUST NOT appear in the receiver's consumed nonce +set.
    3. +
  3. The current time MUST NOT exceed token.expires_at.
    4. +
  4. token.signature MUST verify against the public key of +token.issuer_did.
    5. +
+If all checks pass, the receiver MUST immediately add token.nonce +to its consumed nonce set. A nonce, once consumed, MUST never be +accepted again. +
+
+ +
Six-Phase Handshake +The session handshake consists of six phases. Each phase involves +a message exchange between the initiating agent (I) and the +receiving agent (R). + +Phase Direction Message Data +----- --------- ------------------- -------------------------------- +1a I -> R TokenPresentation CapabilityToken +1b R -> I TokenAccepted session_id, receiver_session_did + R -> I TokenRejected reason (terminates handshake) + +2a I -> R SessionDidExchange initiator_session_did +2b R -> I SessionDidAck (empty) + +3a I -> R DisclosureOffer disclosures (may be empty array) +3b R -> I DisclosureAccepted (empty) + +4 R -> I ExecutionResult result (Schema.org JSON-LD) + +5a I -> R ReceiptForCoSign half-signed TransactionReceipt +5b R -> I ReceiptCoSigned fully co-signed TransactionReceipt + +6a I -> R SessionClose session_id +6b R -> I SessionClosed (empty) + + +
6.3.1. Phase 1: Token Presentation +The initiating agent presents a signed capability token. The +receiving agent verifies the token (Section 6.2.2). +On acceptance, the receiver MUST: +1. Generate a fresh session keypair (Section 4.4). +2. Create a session in the Initiated state. +3. Return a TokenAccepted message containing the session ID and + the receiver's ephemeral session DID. +On rejection, the receiver MUST return a TokenRejected message +with a reason string. The handshake terminates. +
+ +
6.3.2. Phase 2: Ephemeral DID Exchange +The initiating agent generates its own fresh session keypair and +sends a SessionDidExchange message containing its session DID. +On receipt, the receiver MUST: +1. Transition the session state from Initiated to Open. +2. Store the initiator's session DID. +3. Return a SessionDidAck message. +After Phase 2, both parties have exchanged ephemeral session DIDs. +All subsequent envelope signatures (Section 8.2) MUST use session +keys. +
+ +
6.3.3. Phase 3: Disclosure +The initiating agent sends a DisclosureOffer containing an array +of SD-JWT disclosures (Section 7). The array MAY be empty for +zero-disclosure sessions. +The receiver MUST: +1. Verify each disclosure against the SD-JWT commitment + (Section 7.3). +2. Return a DisclosureAccepted message. +If disclosure verification fails, the receiver SHOULD return an +Error message and close the session. +
+ +
6.3.4. Phase 4: Execution +The receiver executes the requested action and returns an +ExecutionResult message containing a Schema.org JSON-LD result +object. +The session state MUST transition from Open to Executed. +
+ +
6.3.5. Phase 5: Receipt Co-Signing +The initiating agent constructs a TransactionReceipt +(Section 11), signs it with its session key, and sends it as +ReceiptForCoSign. +The receiving agent MUST: +1. Verify the initiator's signature on the receipt. +2. Add its own co-signature using its session key. +3. Return the fully co-signed receipt as ReceiptCoSigned. +
+ +
6.3.6. Phase 6: Session Close +Either party MAY initiate session close by sending a +SessionClose message containing the session ID. +On receipt of SessionClose, the other party MUST: +1. Return a SessionClosed message. +2. Transition the session state to Closed. +3. Discard all ephemeral session keys. +After Phase 6, both parties MUST discard their session keypairs. +Session DIDs MUST NOT be reused. +
+
+
+ +
SD-JWT Disclosure Protocol + +
Overview +PAP uses Selective Disclosure JWT (SD-JWT) as defined in +[SD-JWT-08] for context disclosure during the session handshake. +SD-JWT allows the principal to hold multiple claims but disclose +only those permitted by the mandate. +
+ +
SD-JWT Object +An SD-JWT MUST contain: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
issuerStringREQUIREDDID of the claim issuer (typically the principal)
claimsObjectREQUIRED (private)All claims as key-value pairs
saltsObjectREQUIRED (private)Per-claim random salts (UUID v4)
signatureString or nullOPTIONALEd25519 signature over commitment bytes (base64url-no-pad)
The claims and salts fields are private to the holder and +MUST NOT be transmitted in their entirety. Only selected +disclosures (Section 7.3) are transmitted. +
+ +
Disclosure Object +A disclosure reveals a single claim. It MUST contain: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
saltStringREQUIREDThe claim-specific random salt
keyStringREQUIREDThe claim key
valueAny JSON valueREQUIREDThe claim value
+ +
Commitment Computation +The SD-JWT commitment is signed to bind all possible disclosures. + +
    +
  1. For each claim (key, value) with salt s: + +
      +
    • Construct: {"salt": s, "key": key, "value": value}
      • +
    • Hash: SHA-256(JSON_bytes(disclosure))
      • +
    • Encode: base64url-no-pad
      • +
    2. +
  2. Collect all hashes and sort lexicographically. +
    3. +
  3. Construct commitment bytes: + +{ + "issuer": "<issuer_did>", + "disclosure_hashes": ["<sorted_hash_1>", "<sorted_hash_2>", ...] +} + +
    4. +
  4. Sign: Ed25519_sign(JSON_bytes(commitment)) +
    5. +
+
+ +
Disclosure Verification +A verifier MUST: + +
    +
  1. Verify the SD-JWT signature over the commitment bytes using the +issuer's public key.
    2. +
  2. For each received disclosure: +a. Compute hash = base64url(SHA-256(JSON_bytes(disclosure))). +b. Verify that hash is present in the signed + disclosure_hashes array.
    3. +
+If any disclosure hash is not found in the commitment, the +verification MUST fail. +
+ +
Zero-Disclosure Sessions +A session MAY proceed with zero disclosures. In this case: + +
    +
  • The DisclosureOffer message carries an empty disclosures array.
    • +
  • The SD-JWT signature MUST still verify (the commitment contains +hashes for all claims, but none are revealed).
    • +
  • The receiver MUST accept an empty disclosure set without error.
    • +
+
+
+ +
Protocol Messages and Envelope + +
Protocol Message Types +All protocol messages are serialized as JSON objects with a type +discriminator field. The following message types are defined: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

8.2.1. Envelope Signing +The signable bytes for an envelope MUST be computed as: + +SHA-256(session_id_bytes || sequence_big_endian_8_bytes || payload_json_bytes) + +Where || denotes concatenation and sequence_big_endian_8_bytes +is the sequence number as an 8-byte big-endian integer. +Before Phase 2 (DID exchange), the signature field MAY be null +because the capability token carries its own signature from the +issuer. +After Phase 2, all envelopes MUST be signed by the sender's +ephemeral session key. +
+ +
8.2.2. Envelope Verification +The recipient MUST: + +
    +
  1. Verify recipient matches its own DID.
    2. +
  2. Verify sequence is strictly greater than the last received +sequence number for this session.

Marketplace Advertisement Schema + +
Agent Advertisement +An agent advertisement declares an agent's capabilities, disclosure +requirements, and return types. Advertisements use Schema.org +vocabulary and JSON-LD structure. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Disclosure Filtering +A marketplace registry MUST support two query modes: +Query by action: Return all advertisements whose capability +array contains the requested action type. +Query by action with disclosure satisfiability: Return only +advertisements where: +1. The capability array contains the requested action type, AND +2. Every entry in requires_disclosure is present in the caller's + available properties list. +This filtering MUST occur before any mandate is issued or session +is established. Agents whose disclosure requirements exceed the +principal's authorization MUST be excluded. The principal MUST +NOT be asked to over-disclose. +
+ +
Advertisement Signing +The canonical form for advertisement signing MUST include all +fields except signature: + +{ + "@context": "https://schema.org", + "@type": "schema:Service", + "name": "...", + "provider": { ... }, + "capability": [...], + "object_types": [...], + "requires_disclosure": [...], + "returns": [...], + "ttl_min": 300, + "signed_by": "did:key:z..." +} + +Signing follows the same Ed25519/base64url-no-pad procedure as +mandate signing (Section 5.2). +A marketplace registry MUST reject unsigned advertisements. +
+ +
Advertisement Hashing +The content hash of an advertisement MUST be computed as: + +base64url(SHA-256(canonical_bytes)) + +This hash is used for deduplication in federated registries +(Section 10). +
+ +
Operator Metrics +An agent advertisement MAY include an operator_metrics field +containing self-reported operational statistics. Metrics are +informational metadata for principal evaluation and MUST NOT be +used by marketplace registries for ranking, sorting, or filtering +query results. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

The operator_metrics field MUST be excluded from the advertisement +content hash (Section 9.5) and signature computation (Section 9.4). +Metrics change over time while the advertisement identity remains +stable. +Anti-ranking requirement: Marketplace registries MUST return +query results in insertion order. Registries MUST NOT rank, sort, +or filter results based on operator metrics. The principal's +orchestrator is responsible for evaluating metrics and making +selection decisions. This requirement prevents marketplace +registries from accumulating ranking power, which would constitute +platform capture. +
+
+ +
Federation Protocol + +
Overview +Federation enables independent marketplace registries to discover +and share agent advertisements. Federation is peer-to-peer with +no central coordinator. +
+ +

Content-Hash Deduplication +When merging remote advertisements, a federated registry MUST: + +
    +
  1. Compute the content hash of each advertisement (Section 9.5).
    2. +
  2. If the hash already exists in the local seen-hashes set, skip +the advertisement.
    3. +
  3. If the advertisement has no signature, skip it.
    4. +
  4. Otherwise, register the advertisement and add its hash to the +seen-hashes set.
    5. +
+This ensures idempotent synchronization and prevents duplicate +entries. +
+ +
Peer Discovery +A registry MAY discover new peers transitively: + +
    +
  1. Query a known peer's /federation/peers endpoint.
    2. +
  2. For each peer in the response not already known, add it to the +local peer list.
    3. +
+Implementations SHOULD implement rate limiting and SHOULD validate +that newly discovered peers are reachable before adding them. +
+ +
Peer Trust Signals +A federation peer MAY present trust signals to establish +credibility with other registries. Trust signals are additive -- +more signals increase confidence but no single signal is +sufficient alone. + +

10.7.3. Vouch Budget +To prevent vouch ring attacks (where colluding peers mutually +vouch to create Sybil identities), implementations SHOULD enforce: + +
    +
  • Vouch budget: Each peer MAY issue at most 3 vouches per year.
    • +
  • Minimum age: A peer MUST be registered for at least 90 days +before it is eligible to vouch for others.
    • +
  • Probationary period: Newly registered peers operate in +probationary status for 60 days. During probation, a peer MAY +receive advertisements but MUST NOT vouch for other peers.
    • +
  • Diverse trust paths: The vouchers for a new peer SHOULD NOT +all trace their own vouching chains through the same set of +peers.

+ +
Co-Signing Protocol + +
    +
  1. The initiator constructs a receipt from the completed session.
    2. +
  2. The initiator computes Ed25519_sign(canonical_bytes) using its +session key and appends the base64url-no-pad encoded signature +to signatures.
    3. +
  3. The initiator sends the half-signed receipt to the receiver.
    4. +
  4. The receiver verifies the initiator's signature against the +initiator's session public key.
    5. +
  5. The receiver computes Ed25519_sign(canonical_bytes) using its +session key and appends its signature to signatures.
    6. +
  6. The receiver returns the fully co-signed receipt.
    7. +
+
+ +
Receipt Verification +To verify a co-signed receipt: + +
    +
  1. The signatures array MUST contain exactly 2 entries.
    2. +
  2. signatures[0] MUST verify against the initiator's session +public key.
    3. +

+ +
Session Attestation +A session attestation is a signed statement by a session +participant recording their assessment of the session outcome. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

A receipt with attestations from both the initiating and receiving +agents is bilaterally attested. Bilaterally attested receipts +carry higher evidentiary weight for operator metric computation. +Attestations are per-action-type. An operator's reputation in one +action domain (e.g., schema:SearchAction) MUST NOT be conflated +with reputation in another domain (e.g., schema:ReserveAction). +
+
+ +
Verifiable Credential Envelope + +
Overview +PAP mandates MAY be wrapped in a W3C Verifiable Credential (VC) +envelope for interoperability with existing credential ecosystems. +The VC envelope is OPTIONAL; implementations MUST support bare +mandates and MAY additionally support VC-wrapped mandates. +
+ +
VC Structure +A PAP Verifiable Credential MUST conform to [VC-DATA-MODEL-2.0]: + +{ + "@context": [ + "https://www.w3.org/ns/credentials/v2", + "https://www.w3.org/ns/credentials/examples/v2" + ], + "id": "urn:uuid:<uuid-v4>", + "type": ["VerifiableCredential", "PAPMandateCredential"], + "issuer": "<issuer_did>", + "issuanceDate": "<rfc3339>", + "expirationDate": "<rfc3339>", + "credentialSubject": { <mandate_payload> }, + "proof": { + "type": "Ed25519Signature2020", + "created": "<rfc3339>", + "verificationMethod": "<did>#key-1", + "proofPurpose": "assertionMethod", + "proofValue": "<base64url-no-pad>" + } +} + +The type array MUST include both "VerifiableCredential" and +"PAPMandateCredential" for discoverability. +
+ +
Credential Signing +The canonical form for VC signing MUST include all fields except +proof: + +{ + "@context": [...], + "id": "...", + "type": [...], + "issuer": "...", + "issuanceDate": "...", + "expirationDate": "..." or null, + "credentialSubject": { ... } +} + +The proofValue is base64url(Ed25519_sign(JSON_bytes(canonical))). +
+
+ +
Extension Points +The following extensions are defined for PAP v1.0. Core extensions +(Sections 13.1--13.4) were introduced in v0.4. Recovery mandates +(Section 13.5), TEE attestation (Section 13.6), and payment proof +validation (Section 13.7) were added in v0.7. All extensions are +OPTIONAL; a conformant implementation MAY support none, some, or +all of them. + +
Payment Proof +A mandate MAY carry a payment_proof field containing a +zero-knowledge payment commitment. PAP does not define the payment +protocol; it defines the integration point. Only cryptographic +commitments are stored -- never amounts, destinations, mints, or +other identifying payment data. +The PaymentProof type is a tagged enum with two variants: + + + + + + + + + + + + + + + + + + + + + + +
VariantInner TypeDescription
LightningBolt11HashSHA-256 of a BOLT-11 invoice payment hash
EcashCashuTokenHashSHA-256 of a Cashu blind-signed token
+
13.1.1. Bolt11Hash +A commitment to a Lightning Network payment. The hash field +contains the base64url-no-pad encoded SHA-256 of the BOLT-11 +invoice payment hash. The preimage is never stored. + +{ + "type": "Lightning", + "hash": "<base64url-no-pad SHA-256>" +} + +
+ +
13.1.2. CashuTokenHash +A commitment to a Cashu ecash token. The hash field contains the +base64url-no-pad encoded SHA-256 of the blind-signed token. The +token itself is never stored. + +{ + "type": "Ecash", + "hash": "<base64url-no-pad SHA-256>" +} + +
+ +
13.1.3. Payment Proof Properties + +
    +
  • The proof contains only a cryptographic commitment hash.
    • +
  • No amounts, destinations, mints, or routing data are stored.
    • +
  • The vendor MUST NOT be able to identify the payer from the proof.
    • +
  • The proof MUST be unlinkable to the principal's identity.
    • +
  • The payment proof is included in the mandate's canonical form for +signing.
    • +
  • If a mandate's scope includes schema:PayAction, a payment proof +SHOULD be attached. Implementations MAY reject mandates that +permit payment actions without a proof.
    • +
+
+ +
13.1.4. Ecash Blind Signature Protocol +PAP includes a reference implementation of the Chaumian blind signature +scheme in the pap-ecash crate. The scheme uses RFC 9474 +RSABSSA-SHA384-PSS (non-augmented variant, randomize = false). +Protocol parameters: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterValue
SchemeRSABSSA-SHA384-PSS (RFC 9474 Section 4.2, non-augmented)
Key size>= 2048 bits (production); 1024 bits (tests only)
CommitmentSHA-256(serial || signature), base64url-no-pad
Serial size32 bytes, randomly chosen by the client
Protocol steps: + +
    +
  1. Request -- client calls ecash_request(serial, mint_pk). +Returns a BlindToken containing a randomly-blinded serial. Only the +blinded_message() bytes are transmitted to the mint.
    2. +
  2. Mint -- mint calls ecash_mint_sign(blinded_msg, keypair). +Returns raw blind-signature bytes to the client.
    3. +
  3. Unblind -- client calls ecash_unblind(blind_token, blind_sig, mint_pk). +Returns the spendable EcashToken { serial, signature }.
    4. +
  4. Attach -- client calls token.to_payment_proof() and includes the +result in the mandate's payment_proof field.
    5. +
  5. Verify -- payee calls ecash_verify(token, mint_pk). Valid tokens +have a correct RSA-PSS signature over serial.
    6. +
  6. Redeem -- payee calls ecash_redeem(token, mint_pk, registry). +Atomically verifies and records serial in the spent registry, +preventing double-spend.
    7. +
+Unlinkability invariant: The random blinding factor applied in step 1 +means that the blinded_message bytes transmitted to the mint are +statistically independent of the final (serial, signature) pair. The +mint cannot link a signing operation to a subsequent redemption. +Double-spend invariant: ecash_redeem MUST return EcashError::DoubleSpend +on any second call with the same serial, regardless of signature validity. +Test vectors: The conformance test suite is in crates/pap-ecash/. +Run the following to generate and verify all test vectors: + +cargo test -p pap-ecash -- --nocapture + +The ecash_test_vector test uses a freshly-generated 1024-bit test key +(test-only size) and serial 0x000...001 (32 bytes). Because +blind-rsa-signatures v0.14 uses OsRng internally (no injectable RNG), +the blinding factor and PSS salt are non-deterministic. The test therefore +validates structural invariants (correct verification, 43-char base64url +commitment) rather than pinning an exact byte value. +C FFI: pap_ecash_mint_keypair_generate, pap_ecash_blind, +pap_ecash_blind_message_bytes, pap_ecash_mint_sign, pap_ecash_unblind, +pap_ecash_verify, pap_ecash_spent_registry_new, pap_ecash_redeem, +pap_ecash_token_payment_proof_commitment. +WASM: EcashMintKeypair, EcashBlindToken, EcashToken, +ecashMintSign, ecashVerify. +
+
+ +
Payment Proof Verification +A receiving agent that requires payment MUST: +1. Extract the payment_proof from the mandate. +2. Validate the proof's structural integrity (valid base64url, + 32-byte SHA-256 commitment). +3. Verify the proof against the payment network (out of band): + - Lightning: verify the BOLT-11 payment hash preimage + - Ecash: verify the Cashu token with the issuing mint +4. Accept or reject the session based on verification. + +
13.2.1. Receipt Payment Proof Commitment +When a transaction receipt is created for a schema:PayAction, +the receipt MUST include a payment_proof_commitment field +containing the commitment hash from the mandate's payment proof. +This enables auditing without revealing payment details. +A receipt validator MUST check: +1. The payment_proof_commitment is present for payment actions. +2. The commitment matches the mandate's payment proof commitment. +3. The commitment is included in the receipt's canonical form for + co-signing. +The verification protocol between the receiving agent and the +payment network is out of scope for this specification. +
+
+ +
Continuity Tokens +A continuity token enables stateful relationships across sessions +without requiring the vendor to retain state. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
schema_typeStringREQUIREDSchema.org type describing the encrypted payload shape
vendor_didStringREQUIREDDID of the vendor that issued this token
encrypted_payloadStringREQUIREDVendor-encrypted state (opaque to orchestrator)
ttlDateTimeREQUIREDExpiry timestamp, set by the principal
issued_atDateTimeREQUIREDIssuance timestamp
+
13.3.1. Continuity Token Lifecycle + +
    +
  1. At session close, the vendor encrypts its internal state and +returns it as a continuity token to the orchestrator.
    2. +
  2. The orchestrator stores the token locally. The vendor retains +nothing.
    3. +
  3. When the principal returns, the orchestrator presents the token +to the vendor.
    4. +
  4. The vendor decrypts the payload and resumes the relationship.
    5. +
  5. The principal controls the TTL. The vendor MUST NOT set or +extend the TTL.
    6. +
  6. To sever the relationship, the principal deletes the token. No +revocation notice is required.
    7. +
+
+ +
13.3.2. Continuity Token Properties + +
    +
  • The schema_type MUST be inspectable by the orchestrator without +decrypting the payload.
    • +
  • The vendor MUST NOT be able to write to the continuity token +without the principal presenting it.
    • +
  • The encrypted payload format is vendor-defined and opaque to the +protocol.
    • +
+
+
+ +
Auto-Approval Policies +An auto-approval policy allows the principal to pre-authorize +certain categories of actions without per-transaction approval. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
nameStringREQUIREDHuman-readable policy name
scopeScopeREQUIREDSubset of the mandate scope this policy applies to
max_valueNumber or nullOPTIONALMaximum transaction value for auto-approval (currency-agnostic)
zero_additional_disclosureBooleanREQUIREDIf true, auto-approve only when zero additional disclosure is required beyond the mandate
authored_atDateTimeREQUIREDTimestamp when the principal authored this policy
+
13.4.1. Auto-Approval Constraints + +
    +
  • The policy scope MUST be contained by the mandate scope +(Section 5.4.5). A policy MUST NOT be more permissive than the +mandate.
    • +
  • Policies are principal-authored and orchestrator-enforced. An +agent MUST NOT trigger a policy change by requesting it.
    • +
  • zero_additional_disclosure defaults to true. When true, the +orchestrator MUST auto-approve only when the agent's disclosure +requirements are fully covered by the existing mandate.
    • +
  • If max_value is set and the transaction value exceeds it, the +orchestrator MUST request explicit principal approval.
    • +
+
+
+ +
M-of-N Social Recovery +Principal identity recovery via a designated notary quorum. No central +recovery authority. The principal designates N notary DIDs at setup +time; any M co-signers from that set can authorize key rotation. + +
13.5.1. Recovery Mandate +A principal creates a RecoveryMandate while they still control their +key, designating the notary set and threshold. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
principal_didStringREQUIREDDID of the principal creating the mandate
thresholdIntegerREQUIREDM: minimum co-signatures required (1 <= M <= N)
notary_didsArray<String>REQUIREDN designated notary DIDs (no duplicates)
created_atDateTimeREQUIREDMandate creation timestamp
signatureStringREQUIREDEd25519 signature by the principal
Constraints: +- threshold MUST be >= 1 and <= notary_dids.length. +- notary_dids MUST NOT contain duplicate entries. +- The mandate MUST be signed by the principal's current key. +- Only one recovery mandate per principal DID. A new mandate + replaces any previous one. +
+ +
13.5.2. Recovery Request +When recovery is needed, a RecoveryRequest is created identifying +the old principal, the new principal keypair, and the authorizing +recovery mandate. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
old_principal_didStringREQUIREDDID of the principal being recovered
new_principal_didStringREQUIREDDID of the new principal keypair
recovery_mandate_hashStringREQUIREDSHA-256 hash of the authorizing RecoveryMandate
requested_atDateTimeREQUIREDRequest timestamp
The canonical bytes of the recovery request are the message that each +notary signs independently. +
+ +
13.5.3. Partial Recovery Signature (Blind) +Each notary signs the recovery request independently. Notaries MUST +NOT communicate with each other during recovery -- they learn nothing +about which other notaries have been contacted (threshold blind +signature scheme). +Before signing, a notary MUST verify: +1. The recovery mandate was signed by the old principal. +2. The notary's own DID is in the designated notary set. +3. The request references the correct recovery mandate hash. +4. The request's old_principal_did matches the mandate. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
notary_didStringREQUIREDDID of the signing notary
signatureStringREQUIREDEd25519 signature over the RecoveryRequest canonical bytes
signed_atDateTimeREQUIREDTimestamp of the notary's signature
+ +
13.5.4. Recovery Proof Assembly +A recovery coordinator collects M partial signatures and assembles a +RecoveryProof. Verification of the proof MUST check: + +
    +
  1. The recovery mandate was signed by the old principal.
    2. +
  2. At least M partial signatures are present.
    3. +
  3. All signers are in the designated notary set.
    4. +
  4. No duplicate signers.
    5. +
  5. All partial signatures are cryptographically valid.
    6. +
+
+ +
13.5.5. Revocation Proof and Broadcast +After successful recovery, a RevocationProof is created and +broadcast to federation peers. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
old_principal_didStringREQUIREDThe revoked DID
new_principal_didStringREQUIREDThe replacement DID
recovery_proof_hashStringREQUIREDSHA-256 hash of the RecoveryProof
revoked_atDateTimeREQUIREDRevocation timestamp
signatureStringREQUIREDEd25519 signature by the new principal key
The revocation proof MUST be signed by the new principal key (proving +possession). Federation peers that receive a valid revocation MUST: +- Mark the old principal DID as revoked. +- Reject any future operations using the old DID. +- Remove the old recovery mandate from their NotarySet. +
+ +
13.5.6. NotarySet Registry +Each federation node maintains a NotarySet -- a registry of recovery +mandates queryable by principal DID. The NotarySet: +- Stores signed recovery mandates. +- Tracks revoked principal DIDs. +- Rejects mandate registration for already-revoked DIDs. +- Processes revocation broadcasts from federation peers. +
+ +
13.5.7. Security Properties + +
    +
  • No central authority. Recovery requires M independent notaries.
    • +
  • Blind co-signing. Notaries do not learn which other notaries +participate in a recovery event.
    • +
  • Old key revocation. The old principal DID is cryptographically +revoked and broadcast to all federation peers.
    • +
  • Notary set immutability. The notary set is fixed at mandate +creation time by the principal. It cannot be modified without +creating a new mandate signed by the principal.
    • +
  • Threshold enforcement. Fewer than M signatures MUST be rejected. +Duplicate signers MUST be rejected.
    • +
+
+
+ +
TEE Attestation +A mandate or session MAY carry a Trusted Execution Environment +(TEE) attestation to provide evidence that an agent is executing +within an isolated enclave. TEE attestation is OPTIONAL and does +NOT elevate a TEE to equivalence with local trust (Section 3.4). + +
13.6.1. Attestation Object + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldTypeRequiredDescription
enclave_typeStringREQUIREDTEE platform identifier (e.g., "sgx", "sev-snp", "trustzone")
measurementStringREQUIREDEnclave measurement hash (base64url-no-pad)
attestation_reportStringREQUIREDPlatform-specific attestation report (base64url-no-pad)
timestampDateTimeREQUIREDAttestation generation timestamp (RFC 3339)
nonceStringREQUIREDChallenge nonce binding this attestation to the current session (UUID v4)
+ +
13.6.2. Attestation Verification +A verifier MUST: + +
    +
  1. Verify the attestation_report against the TEE platform's +root of trust (platform-specific, out of scope).
    2. +
  2. Verify that measurement matches an expected enclave binary +hash (implementation-defined allowlist).
    3. +
  3. Verify that nonce matches the session's challenge nonce.
    4. +
  4. Verify that timestamp is within an acceptable window +(implementations SHOULD reject attestations older than 60 +seconds).
    5. +
+
+ +
13.6.3. Trust Boundaries +TEE attestation provides evidence of code integrity, not +behavioral correctness. Specifically: + +
    +
  • A TEE attestation MUST NOT be treated as equivalent to a +mandate. An agent in a TEE still requires a valid mandate chain.
    • +
  • A TEE attestation MUST NOT be used to expand scope beyond what +the mandate permits.
    • +
  • The principal MAY use TEE attestation as an input to +auto-approval policies (Section 13.4) but MUST NOT be required +to accept TEE attestation as a substitute for consent.
    • +
+
+ +
13.6.4. Implementation Notes +The reference implementation provides TEE attestation support via +the pap-tee crate, which is compiled only when opted into as a +dependency. Integration with pap-core is gated behind the tee +Cargo feature flag. + +
    +
  • pap-tee crate: Defines AttestationEvidence, +EnclaveType, the AttestationVerifier trait, and a +SoftwareSimulator for integration testing without hardware.
    • +
  • pap-core tee feature: Adds an optional attestation +field to Session and provides open_with_attestation().
    • +
  • ProtocolMessage::TokenAccepted: Carries an optional +attestation field as opaque JSON (serde_json::Value). +Receivers parse it via AttestationEvidence::from_value().
    • +
+The SoftwareSimulator uses EnclaveType::Software and signs +attestation reports with an Ed25519 key. It is intended for +conformance testing (Appendix D, tests E-13 through E-15) and +MUST NOT be deployed in production. +
+
+ +
Payment Proof Validation +Section 13.1 defines the payment proof integration point. This +section specifies the validation requirements that a conformant +implementation MUST satisfy when payment proofs are present. + +
13.7.1. Proof Format Registry +PAP defines the following payment proof format prefixes: + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
PrefixProtocolDescription
ecash:blind:v1:Chaumian ecashBlind-signed mint tokens (Section 13.1)
ln:preimage:v1:Lightning NetworkHash preimage proof of payment
zk:receipt:v1:Zero-knowledge proofZK proof of value transfer
Implementations MAY support additional formats using the +pap:payment: namespace prefix. +
+ +
13.7.2. Validation Requirements +A receiving agent that requires payment MUST: + +
    +
  1. Parse the payment_proof field and identify the format prefix.
    2. +
  2. If the format is not supported, reject the mandate with a +PaymentFormatUnsupported error.
    3. +
  3. Verify the proof against the appropriate payment backend +(mint, Lightning node, or ZK verifier). The verification +protocol is out of scope for this specification.
    4. +
  4. Verify that the proof amount meets the agent's minimum +requirement for the requested action.
    5. +
  5. Verify that the proof has not been previously consumed +(double-spend protection).
    6. +
+
+ +
13.7.3. Privacy Requirements + +
    +
  • Payment proof verification MUST NOT reveal the payer's +identity to the payment backend.
    • +
  • The receiving agent MUST NOT store payment proofs beyond the +session duration unless required by applicable law.
    • +
  • Payment proofs MUST NOT appear in transaction receipts +(Section 11.5).
    • +
+
+
+ +
Chat and Real-Time Communication + +
13.8.1. Overview +PAP provides a natural foundation for zero-trust, privacy-preserving +real-time communication between principals. A personal agent MAY +advertise schema:CommunicateAction in the federation registry -- exactly +as a service agent advertises schema:SearchAction. This makes a +principal discoverable for chat without requiring a phone number, +email address, or centrally-administered identity. Discoverability is +opt-in, scoped, and revocable through the standard mandate system. +Chat is not a new protocol. It is the Phase 4 streaming extension of +the standard 6-phase handshake, applied to a schema:CommunicateAction +session. +
+ +
13.8.2. Capability Grant +A CapabilityToken scoped to schema:CommunicateAction MUST be issued +by the initiating principal (or a delegated orchestrator) and signed with +a principal key. The token: + +
    +
  • MUST set action = "schema:CommunicateAction".
    • +
  • MUST set target_did to the receiving principal's agent DID.
    • +
  • MAY set a ttl appropriate for the conversation duration.
    • +
  • MAY carry a scope restricting the permitted communication modes +(e.g., text-only, text+audio, text+audio+video).
    • +
+
+ +
13.8.3. Phase 4 Streaming Mode +After Phase 3 (disclosure), instead of a single task execution, +the session transitions to streaming mode: + +
    +
  1. Phase 4 execute (client -> server, no payload): the receiving +agent returns ExecutionResult containing a schema:Conversation +JSON-LD object. This signals that the session SHOULD remain open. +
    2. +
  2. StreamingMessage frames (bidirectional, Phase 4): either party +MAY send StreamingMessage frames carrying DIDComm basicmessage +protocol payloads (see Section 13.8.5). Each frame MUST include: + +
      +
    • id: a UUID for ack correlation.
      • +
    • content: a JSON object conforming to the DIDComm basicmessage +body schema.
      • +
    3. +
  3. StreamingAck (responding side): upon receiving a StreamingMessage, +the server MUST reply with either a StreamingAck (delivery confirmed) +or a StreamingMessage (reply). +
    4. +
  4. The session MUST remain open until either party sends SessionClose +(Phase 6). Implementations SHOULD NOT proceed to Phase 5 (receipt +co-signing) until the conversation is concluded. +
    5. +
+
+ +
13.8.4. Message Format (DIDComm basicmessage) +The content field of each StreamingMessage MUST conform to the +DIDComm basicmessage 2.0 protocol body: + +{ + "type": "https://didcomm.org/basicmessage/2.0/message", + "id": "<UUID>", + "body": { + "content": "<text of message>" + } +} + +The DIDComm wrapping (plaintext, signed, or encrypted) is applied at the +Envelope layer via PapToDIDComm (Section 5.6). For chat sessions, +implementations SHOULD use at minimum DIDCommSigned to bind each +message to the sender's session DID. +
+ +
13.8.5. Receipt +Upon SessionClose, the receipt (Phase 5) MUST record: + +
    +
  • action = "schema:CommunicateAction"
    • +
  • executed: a summary string, e.g., "schema:Conversation".
    • +
  • disclosed_by_initiator / disclosed_by_receiver: property +references only (e.g., ["schema:name"]). Message content +MUST NOT appear in receipts.
    • +
  • Both parties' session DIDs as initiating_agent_did / +receiving_agent_did (ephemeral, unlinked from principal DIDs).
    • +
+
+ +
13.8.6. Group Chat Rooms +A group chat room is an agent with its own DID that implements +AgentHandler and maintains one session per member: + +
    +
  • The room DID is registered in the federation with +capability: ["schema:CommunicateAction"].
    • +
  • The room owner issues a separate CapabilityToken to each +member, all targeting the room DID.
    • +
  • Each member runs the standard 6-phase handshake against the +room DID. After Phase 4 (streaming mode open), the room agent +fans out each StreamingMessage to all other connected members.
    • +
  • Group membership is enforced by the token system: only principals +holding a valid token may connect. Revocation follows the standard +mandate revocation flow (Section 8).
    • +
  • Rooms MAY be hosted locally (Papillon instance) or on any +federation peer. A room hosted on a federation peer is +discoverable via its DID advertisement.
    • +
+
+ +
13.8.7. Audio and Video +Audio and video calls follow the same pattern as text chat, using +WebRTC as the media transport: + +
    +
  1. PAP Phases 1-4 establish identity, authorization, and streaming +mode. The CapabilityToken scope SHOULD include the permitted +media types (e.g., text+audio+video).
    2. +
  2. SDP negotiation is carried via StreamingMessage frames: +the offerer sends a StreamingMessage whose content.body +contains the SDP offer; the answerer replies with SDP answer. +ICE candidates are exchanged as subsequent frames.
    3. +
  3. WebRTC DTLS-SRTP establishes the media channel out-of-band. +PAP does not inspect or relay media.
    4. +
  4. Implementations MAY route ICE/TURN through an OHTTP relay to +conceal participant IP addresses.
    5. +
  5. The PAP receipt records call metadata (duration, participant +session DIDs, permitted media scope) but MUST NOT include +audio or video content.
    6. +
+
+ +
13.8.8. Privacy Properties +Chat sessions inherit all PAP privacy guarantees: + +
    +
  • Ephemeral session DIDs -- neither party's principal DID +appears in message frames or SDP.
    • +
  • OHTTP relay -- IP addresses hidden from the relay operator.
    • +
  • Receipts -- property references only; no message content.
    • +
  • Discoverability -- controlled by the principal's federation +advertisement; opt-in.
    • +
  • Forward secrecy -- DIDComm anoncrypt (ECDH-ES + A256GCM) +MAY be applied to StreamingMessage content for per-message +forward secrecy.
    • +
+
+
+
+ +
Transport Binding + +
HTTP/JSON Transport +PAP defines an HTTP/JSON transport binding for the 6-phase +handshake. This binding is the default transport for PAP v1.0. +Implementations MAY define additional transport bindings. +
+ +
Agent Server Endpoints +A receiving agent MUST expose the following HTTP endpoints: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
MethodPathPhaseRequestResponse

POST/session/{id}/receipt5ReceiptForCoSignReceiptCoSigned
POST/session/{id}/close6SessionCloseSessionClosed
The {id} path parameter is the session ID returned in Phase 1. +
+ +
Agent Handler Interface +Implementations MUST implement a handler interface with the +following operations: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

handle_disclosure3session_id, disclosures()
execute4session_idJSON result
co_sign_receipt5TransactionReceiptTransactionReceipt (co-signed)
handle_close6session_id()
+ +
Endpoint Resolution +Endpoint resolution maps a DID to a transport endpoint URL. In +production, this SHOULD be backed by DID Document service +endpoints. Implementations MAY use in-memory registries for +development and testing. +
+ +
Content Type +All HTTP request and response bodies MUST use Content-Type: +application/json. Implementations SHOULD set Accept: +application/json on requests. +
+ +
Error Handling +If a phase handler returns an error, the server MUST respond with +HTTP status 500 and a ProtocolMessage::Error payload containing +a code and message. +If the request body does not match the expected message type for +the endpoint, the server MUST respond with HTTP status 400. +
+ +
WebSocket Transport +Implementations MAY support a WebSocket transport binding as an +alternative to the HTTP/JSON binding. The WebSocket binding is +OPTIONAL and provides full-duplex communication for sessions that +benefit from lower-latency message exchange. + +
14.7.1. Connection Lifecycle + +
    +
  1. The initiating agent opens a WebSocket connection to the +receiving agent's WebSocket endpoint.
    2. +
  2. All 6 phases of the session handshake (Section 6.3) are +conducted as JSON messages over the WebSocket connection.
    3. +
  3. Each message MUST be a JSON-serialized Envelope (Section 8.2).
    4. +
  4. The connection MUST be closed after Phase 6 (session close).
    5. +
+
+ +
14.7.2. Endpoint Format +A WebSocket endpoint MUST use the wss:// scheme. Implementations +MUST NOT use unencrypted ws:// connections in production. +The endpoint URL MUST be published in the agent's DID Document +service array with type set to "PAPWebSocket": + +{ + "id": "did:key:z...#pap-ws", + "type": "PAPWebSocket", + "serviceEndpoint": "wss://agent.example.com/pap/ws" +} + +
+ +
14.7.3. Message Framing +Each WebSocket text frame MUST contain exactly one JSON-serialized +Envelope. Binary frames MUST NOT be used. Implementations MUST +reject connections that send binary frames. +
+ +
14.7.4. Sequence Enforcement +Envelope sequence number rules (Section 8.2.2) apply identically +over WebSocket. Out-of-order messages MUST be rejected. +
+
+ +
Oblivious HTTP (OHTTP) Transport +Implementations MAY support Oblivious HTTP [RFC 9458] as a +transport binding. OHTTP provides request unlinkability at the +network layer, preventing the receiving agent's operator from +correlating requests by IP address. + +
14.8.1. Architecture +An OHTTP deployment interposes a relay between the initiating +agent and the receiving agent: + +Initiator -> OHTTP Relay -> Receiving Agent (Gateway) + +The relay sees the initiator's IP but not the request content. +The receiving agent sees the request content but not the +initiator's IP. +
+ +
14.8.2. Encapsulation +Each PAP protocol message MUST be encapsulated as an OHTTP +Binary HTTP request targeting the corresponding HTTP/JSON +endpoint (Section 14.2). The Content-Type MUST remain +application/json. +
+ +
14.8.3. Key Configuration +The receiving agent MUST publish its OHTTP key configuration +in its DID Document service array with type set to +"PAPObliviousHTTP": + +{ + "id": "did:key:z...#pap-ohttp", + "type": "PAPObliviousHTTP", + "serviceEndpoint": "https://agent.example.com/pap/ohttp", + "ohttpKeyConfig": "<base64url-encoded-key-config>" +} + +
+ +
14.8.4. Relay Selection +The initiating agent selects the OHTTP relay. The relay MUST +NOT be operated by the same entity as the receiving agent. The +protocol does not define relay discovery; implementations +SHOULD allow the principal to configure trusted relays. +
+
+ +
DIDComm Transport +Implementations MAY support DIDComm Messaging v2 [DIDCOMM-V2] +as a transport binding. DIDComm provides authenticated encryption +at the message layer, enabling transport-independent secure +messaging between agents identified by DIDs. + +
14.9.1. Message Mapping +Each PAP protocol message (Section 8.1) MUST be wrapped in a +DIDComm plaintext message with the following mapping: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
DIDComm FieldValue
typehttps://pap.dev/protocol/1.0/{message_type}
fromSender's DID (session DID after Phase 2)
toArray containing recipient's DID
bodyThe PAP protocol message payload
created_timeEnvelope timestamp (Unix epoch seconds)
Where {message_type} is the lowercase, hyphenated form of the +PAP message type (e.g., token-presentation, session-did-exchange). +
+ +
14.9.2. Encryption +DIDComm messages MUST use authenticated encryption (authcrypt) +after Phase 2 when both session DIDs are known. Phase 1 messages +MAY use anonymous encryption (anoncrypt) since the initiator's +session DID is not yet established. +
+ +
14.9.3. Service Endpoint +A DIDComm-capable agent MUST publish a DIDComm service endpoint +in its DID Document: + +{ + "id": "did:key:z...#pap-didcomm", + "type": "DIDCommMessaging", + "serviceEndpoint": { + "uri": "https://agent.example.com/pap/didcomm", + "accept": ["didcomm/v2"] + } +} + +
+
+ +
Transport Negotiation +When an agent supports multiple transport bindings, the initiating +agent MUST select a transport by inspecting the receiving agent's +DID Document service array. The preference order SHOULD be: + +
    +
  1. OHTTP (strongest privacy properties)
    2. +
  2. DIDComm (authenticated encryption at message layer)
    3. +
  3. WebSocket (lower latency for interactive sessions)
    4. +
  4. HTTP/JSON (default, widest compatibility)
    5. +
+If the receiving agent's DID Document contains no service +entries, the initiating agent MUST fall back to HTTP/JSON with +endpoint resolution (Section 14.4). +
+ +
DIDComm v2 Envelope Compatibility +PAP defines an optional DIDComm v2 envelope compatibility layer +that wraps PAP protocol envelopes inside DIDComm v2 message +formats. This allows PAP agents to interoperate with +DIDComm-native agents without changing the PAP protocol itself. +This section specifies the detailed wire formats used by the +DIDComm transport binding (Section 14.9). + +
14.11.1. Design Principles + +
    +
  • PAP mandate, session, and receipt semantics are fully preserved.
    • +
  • Only the outer transport envelope changes; the inner PAP +Envelope (including its Ed25519 signature) travels intact +inside the DIDComm message body.
    • +
  • The DIDComm layer provides additional transport-level integrity +(JWS) or confidentiality (JWE) on top of PAP's own signatures.
    • +
  • This is a shim -- existing pap-transport behavior is unaffected.
    • +
+
+ +
14.11.2. Plaintext Messages +A PAP envelope is wrapped in a DIDComm v2 plaintext message: + +{ + "id": "<uuid>", + "typ": "application/didcomm-plain+json", + "type": "https://pap.baur.dev/proto/1.0/<message-slug>", + "from": "<sender-did>", + "to": ["<recipient-did>"], + "created_time": <unix-timestamp>, + "body": { <full PAP Envelope as JSON> } +} + +The type field uses PAP message type URIs under the namespace +https://pap.baur.dev/proto/1.0/, with kebab-case slugs derived +from the ProtocolMessage variant name (e.g., session-did-ack, +execution-result, token-presentation). +The body field contains the complete PAP Envelope including +its signature field, so the receiving agent can verify the +PAP-level signature independently of the DIDComm layer. +
+ +
14.11.3. Signed Messages (Ed25519 JWS) +A signed DIDComm v2 message uses JWS General JSON Serialization +(RFC 7515) with the EdDSA algorithm (RFC 8037): + +{ + "payload": "<base64url(plaintext-json)>", + "signatures": [{ + "protected": "<base64url({\"typ\":\"application/didcomm-signed+json\",\"alg\":\"EdDSA\"})>", + "signature": "<base64url(Ed25519-signature)>" + }] +} + +The signing input is ASCII(protected) || '.' || ASCII(payload) +where both values are base64url-encoded without padding (RFC 4648 +Section 5). The signature is computed with Ed25519 (RFC 8032). +Verifiers MUST reject messages where: +- The alg header value is not "EdDSA". +- The signature does not verify against the expected key. +- The decoded payload is not valid DIDComm v2 plaintext JSON. +
+ +
14.11.4. Encrypted Messages (ECDH-ES + A256GCM JWE) +An encrypted DIDComm v2 message uses JWE JSON Serialization with +anonymous encryption (anoncrypt): + +
    +
  • Key Agreement: ECDH-ES (direct, no key wrapping) via +X25519 Diffie-Hellman. The sender generates an ephemeral X25519 +keypair. The recipient's Ed25519 public key is converted to +X25519 using the Edwards-to-Montgomery birational map.
    • +
  • Key Derivation: Concat KDF (NIST SP 800-56A Section 5.8.1) +with algId = "A256GCM", empty apu, and +apv = SHA-256(recipient-did).
    • +
  • Content Encryption: AES-256-GCM with a random 96-bit IV. +The base64url-encoded protected header serves as Additional +Authenticated Data (AAD).
    • +
+ +{ + "protected": "<base64url(header-json)>", + "recipients": [{ + "header": { "kid": "<recipient-did>" }, + "encrypted_key": "" + }], + "iv": "<base64url(96-bit-nonce)>", + "ciphertext": "<base64url(aes-gcm-ciphertext)>", + "tag": "<base64url(128-bit-auth-tag)>" +} + +The protected header contains: + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
FieldValue
typ"application/didcomm-encrypted+json"
alg"ECDH-ES"
enc"A256GCM"
epk{"kty":"OKP","crv":"X25519","x":"<base64url-pubkey>"}
apv"<base64url(SHA-256(recipient-did))>"
The encrypted_key field is empty for ECDH-ES direct key +agreement (the content encryption key is derived directly from +the shared secret). +
+ +
14.11.5. Ed25519 to X25519 Key Conversion +DIDComm v2 encryption requires X25519 keys for key agreement. +PAP agents use Ed25519 keys (via did:key). The conversion is: + +
    +
  • Public key: Decompress the Ed25519 compressed Edwards Y +coordinate, then apply the Edwards-to-Montgomery birational map +to obtain the X25519 public key (32 bytes).
    • +
  • Private key: Compute SHA-512(Ed25519-seed)[0..32]. The +X25519 library applies standard clamping (clear bits 0-2, +clear bit 255, set bit 254).
    • +
+This conversion is consistent: the X25519 public key derived from +the converted private key matches the X25519 public key derived +from the original Ed25519 public key. +
+ +
14.11.6. Translation Rules + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+ +
PAP URI Scheme + +
Overview +The pap URI scheme identifies agents, capabilities, and resources within +the Principal Agent Protocol. A pap:// URI is always an expression of +intent -- resolving one initiates a PAP mandate-scoped interaction, not +a raw network request. +The scheme family consists of three variants: + + + + + + + + + + + + + + + + + + + + + + + + +
SchemeMeaning
pap://PAP-native transport; client negotiates protocol
pap+https://PAP mandate scope applied over HTTPS transport
pap+wss://PAP mandate scope applied over WebSocket transport
pap+https:// and pap+wss:// are recapture schemes. They apply PAP +semantics -- mandate enforcement, selective disclosure, co-signed receipts -- +to existing transports. The remote endpoint does not need to implement PAP. +The client enforces the protocol locally. A pap+https:// URI is still an +HTTPS request under the hood; the principal's mandate scope wraps it +regardless of whether the server is PAP-aware. +
+ +
Syntax + +pap-uri = pap-scheme "://" pap-authority pap-path [ "?" pap-query ] + +pap-scheme = "pap" / "pap+https" / "pap+wss" + +pap-authority = registry-host / did-authority / catalog-name + +registry-host = host [ ":" port ] + ; authority is the hostname only; agent slug appears in path + +did-authority = "did:key:" base58-multicodec-key + ; PAP parsers MUST treat "did:key:" as an atomic authority + ; token. Standard RFC 3986 host parsing (which disallows + ; colons) MUST NOT be applied to did-authority. A PAP URI + ; parser identifies did-authority by the "did:key:" prefix + ; before applying any other rule. + +catalog-name = 1*( ALPHA / DIGIT / "-" / "_" ) + ; MUST NOT be a reserved word (receipt, canvas, settings) + ; resolved against local catalog before dispatch + +pap-path = registry-path / simple-path + +registry-path = "/agents/" agent-slug "/" schema-action-type +simple-path = "/" schema-action-type + ; Schema.org action type, e.g. "SearchAction" + +pap-query = pap-param *( "&" pap-param ) +pap-param = schema-property "=" pap-value + ; values MUST be percent-encoded per RFC 3986 Section 2.1 + ; "+" MUST NOT be used as a space encoding in pap-query + +Examples: + +; Networked agent via Chrysalis registry +pap://chrysalis.example.com/agents/arxiv/SearchAction?query=quantum%20computing + +; Direct peer-to-peer via DID (no registry) +pap://did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK/SearchAction + +; Local catalog shorthand -- resolved before dispatch +pap://arxiv/SearchAction?query=quantum%20computing +pap://wikipedia/ReadAction?name=Rust%20programming + +; Receipt deep-link +pap://receipt/RCP_abc123 + +; Recapture schemes -- PAP scope over existing transports +pap+https://api.example.com/agents/bookings/BuyAction?offer=flight-abc +pap+wss://stream.example.com/agents/feed/ListenAction + +
+ +
Resolution +A conforming client MUST resolve a pap:// URI using the following +priority chain, in order: + +
    +
  1. Special authority -- if the authority is one of the reserved words +(receipt, canvas, settings), resolve locally without any network +lookup. See Section 15.7. Do not proceed to subsequent steps. +
    2. +
  2. did:key: authority -- if the authority begins with did:key:, +resolve directly via DID Document endpoint discovery (Section 14.4). +No registry lookup. Initiates a PAP handshake with the identified agent. +
    3. +
  3. Catalog name -- if the authority contains no . character and does +not begin with did:, the client MUST check its local agent catalog for +an entry whose name field matches the authority (case-insensitive). If +found, rewrite the URI to the agent's registered DID and resolve via +step 1. +
    4. +
  4. Registry hostname -- if the authority contains a . character, or +matches localhost, or is a valid IPv4 address or IPv6 literal, treat it +as a Chrysalis registry host. Resolve by querying the registry's +/agents/{slug}/ routes (Section 14.1) using the path-embedded agent +slug, and initiate a PAP handshake with the returned agent endpoint. +The . heuristic MUST NOT be applied to localhost or IP literals; +they are always treated as registry hosts. +
    5. +
+If resolution fails at all steps, the client MUST render an inline error in +place of the activated link, showing the unresolved URI and a human-readable +explanation. The client MUST NOT navigate away from the current canvas or +dismiss existing content. The client MUST NOT silently fall back to a raw +HTTP request. +
+ +
Action Type and Query Parameters +The action type path segment MUST be a Schema.org action type +(e.g. SearchAction, BuyAction, ReadAction). For registry URIs the +full path is /agents/{slug}/{ActionType}; for catalog and DID URIs the +path is /{ActionType}. Clients SHOULD use the action type to pre-filter +agents during resolution -- if a catalog agent does not advertise the +requested action type in its capability array, it MUST NOT be selected. +Query parameters MUST use Schema.org property names as keys. Values MUST +be percent-encoded per RFC 3986 Section 2.1; + MUST NOT be used as a space +encoding. Clients MAY pass query parameters directly to the agent as the +intent payload. Agents MAY ignore unknown parameters. +
+ +
Recapture Semantics (pap+https://, pap+wss://) +When a pap+https:// or pap+wss:// URI is resolved: + +
    +
  1. The active mandate scope MUST be checked before the request is made. If +no mandate is in scope, the client MUST NOT proceed. +
    2. +
  2. The request is made over the underlying transport (HTTPS or WSS) with +the standard PAP session headers included where the server accepts them. +
    3. +
  3. The client MUST record what was disclosed and generate a receipt entry +regardless of whether the server participates in the PAP handshake. +
    4. +
  4. The remote endpoint's response is treated as agent output and rendered +via the standard block renderer pipeline. +
    5. +
+For pap+wss:// URIs, the connection lifecycle (establishment, keepalive, +and termination) follows the mandate-scoped session lifecycle defined in +Section 5. Streaming-specific semantics (chunked responses, event framing) are +deferred to v1.1. +This allows principals to bring existing web services under PAP governance +without requiring those services to be modified. +v1.0 scope note: In v1.0, pap+https:// and pap+wss:// URIs are +parsed and classified by conforming clients. Full mandate enforcement +(steps 1-4 above) requires the mandate enforcement layer, which is deferred +to a post-v1.0 milestone. v1.0 clients MUST NOT silently downgrade a +pap+https:// URI to an unscoped HTTPS request. They MUST either enforce +the mandate or reject the request with a clear principal-visible error +explaining that recapture enforcement is not yet available. +
+ +
Link Rendering +Any string value in a JSON-LD agent response that begins with pap://, +pap+https://, or pap+wss:// MUST be rendered as a navigable link by +conforming clients. Activating such a link MUST dispatch the URI as intent +through the same pipeline as a principal-typed query -- it is not a browser +navigation event. +This enables agent-rendered content to form a navigable graph of +intent-links without requiring any special page routing. Every link is a +new PAP interaction. +Agent-rendered link security: Clients MUST visually distinguish links +originating from agent-rendered content from links typed directly by the +principal. Before dispatching an agent-rendered pap:// link, clients +SHOULD display the full URI and the identity of the agent that produced it, +and require explicit principal confirmation. This prevents injection attacks +where a malicious or compromised agent response induces the client to +execute unintended actions. +Agent-rendered links MUST NOT activate the settings, canvas, or +receipt special authorities (Section 15.7). Clients MUST silently reject +such links and MAY log the attempt for principal review. +
+ +
Special Authorities +The following authority values are reserved and MUST be handled by the +client without registry or catalog lookup: + + + + + + + + + + + + + + + + + + + + + + + + +
AuthorityMeaning
receiptDeep-link to a receipt by session ID. pap://receipt/{session-id} opens the receipt detail view.
canvasDeep-link to a canvas block. pap://canvas/{canvas-id}/{block-id} navigates to the referenced block.
settingsOpens the settings panel. pap://settings/{tab} opens a specific tab.
+
+ +
Security Considerations + +
Cryptographic Algorithms +PAP v1.0 uses exclusively: + +
    +
  • Ed25519 (RFC 8032) for all signatures.
    • +
  • SHA-256 (FIPS 180-4) for all hashes.
    • +
  • Base64url without padding (RFC 4648 Section 5) for all +binary-to-text encoding.
    • +
  • Base58btc for DID key encoding.
    • +
+Implementations MUST use these algorithms for PAP v1.0. All signable +structures carry a SignatureAlgorithm field (serialized as the JWS +alg string, e.g. "EdDSA") to enable forward-compatible algorithm +negotiation. The field defaults to Ed25519 when absent. Implementations +MUST reject algorithms they do not support. The did:key multicodec +prefix encodes the algorithm of the public key. +Future versions of this specification MAY introduce additional algorithms +(e.g., ML-DSA-65 for post-quantum resistance). +
+ +
Key Management + +
    +
  • Principal private keys SHOULD be stored in hardware security +modules or platform authenticators (WebAuthn). They MUST NOT be +stored in plaintext in configuration files or environment +variables in production.
    • +
  • Session private keys MUST be held only in memory for the +duration of the session. They MUST NOT be persisted to disk.
    • +
  • Signing keys for agent operators (used to sign advertisements) +SHOULD be protected with access controls appropriate to the +deployment environment.
    • +
+
+ +
Nonce Management + +
    +
  • Capability token nonces MUST be stored in a consumed-nonce set +for at least the duration of the token's validity period.
    • +
  • Implementations SHOULD periodically purge expired nonces to +prevent unbounded growth of the consumed-nonce set.
    • +
  • If a receiver restarts and loses its consumed-nonce set, it +SHOULD reject all tokens issued before the restart by comparing +issued_at against its restart timestamp.
    • +
+
+ +
Replay Protection +Multiple layers provide replay protection: + +
    +
  1. Token nonces: Each capability token has a UUID v4 nonce +consumed on first use.
    2. +
  2. Envelope sequencing: Sequence numbers are monotonically +increasing within a session. Out-of-order envelopes MUST be +rejected.
    3. +
  3. Token expiry: Tokens carry an expires_at timestamp. +Expired tokens MUST be rejected.
    4. +
  4. Session ephemerality: Session keys are discarded at close. +A replayed session message cannot be verified against the +original session keys.
    5. +
+
+ +
Denial of Service + +
    +
  • Implementations SHOULD rate-limit token presentation requests +to prevent resource exhaustion from session initiation floods.
    • +
  • Federation sync operations SHOULD be rate-limited per peer.
    • +
  • Marketplace registries SHOULD limit the number of advertisements +per operator DID.
    • +
+
+ +
Man-in-the-Middle + +
    +
  • After Phase 2 (DID exchange), all envelopes MUST be signed by +the sender's session key. An attacker who intercepts envelopes +cannot forge valid signatures without the session private key.
    • +
  • The initial token presentation (Phase 1) is protected by the +orchestrator's signature on the capability token. An attacker +cannot forge a valid token without the orchestrator's private +key.
    • +
  • Implementations SHOULD use TLS for all HTTP transport to protect +against passive eavesdropping.
    • +
+
+ +
Context Leakage + +
    +
  • The DisclosureOffer (Phase 3) MUST contain only SD-JWT +disclosures permitted by the mandate's disclosure set.
    • +
  • The orchestrator MUST verify that the agent's +requires_disclosure is satisfiable by the mandate before +issuing a capability token. An agent MUST NOT receive a token +if its disclosure requirements exceed the principal's +authorization.
    • +
  • Receipts MUST NOT contain personal data values (Section 11.5).
    • +
+
+ +
Mandate Chain Depth +Implementations SHOULD enforce a maximum mandate chain depth to +prevent resource exhaustion during chain verification. A maximum +depth of 10 is RECOMMENDED. +
+ +
Clock Skew + +
    +
  • Implementations MUST use UTC for all timestamps.
    • +
  • Implementations SHOULD tolerate clock skew of up to 30 seconds +for token expiry and mandate TTL checks.
    • +
  • Implementations MAY use NTP or similar time synchronization +protocols to minimize skew.
    • +
+
+ +
Canonical JSON Determinism +The security of mandate hashing and signature verification depends +on deterministic JSON serialization. Implementations MUST ensure +that the canonical JSON form produces identical bytes for the same +logical content. +Implementations SHOULD: +- Use a JSON serializer that produces consistent key ordering. +- Represent numbers without unnecessary precision. +- Use RFC 3339 with explicit UTC offset for all timestamps. +If an implementation cannot guarantee deterministic JSON output, +it MUST use an alternative canonical form (e.g., JCS [RFC 8785]) +and document the choice. +

Problem Statement + +Existing agent-to-agent protocols authenticate agents as platform +entities, not as delegates of human principals. None enforce context +minimization at the protocol level. Disclosure is +implementation-dependent. Session ephemerality is undefined. Execution +isolation is absent—agents run in the same address space as the +orchestrator or other services, creating blast radius problems even +when disclosure is minimized. Economic models underneath these +protocols are compatible with platform capture through cloud compute +metering. + +### 1.2. Design Goals + +PAP is designed to satisfy the following goals: + +1. The human principal is the root of trust for every transaction. +2. Context disclosure is enforced by the protocol at the request boundary (via SD-JWT). +3. Execution is isolated at the process boundary via OS-level capabilities. +4. Sessions are ephemeral by design; no persistent correlation. +5. Delegation is hierarchical with cryptographically enforced bounds. +6. Co-signed receipts prove both disclosure scope and execution constraints. +7. No novel cryptography, no token economy, no central registry. +8. Any compliant implementation MUST be buildable from this document + alone, without reference to a specific programming language. + +### 1.3. Protocol Overview + +A PAP transaction involves: + +- A **human principal** who holds a device-bound keypair. +- An **orchestrator agent** operating under a root mandate. +- One or more **downstream agents** operating under delegated mandates, each executing in sandboxed isolation. +- A **marketplace** for agent discovery and disclosure filtering. +- A **6-phase session handshake** between pairs of agents. +- **Request boundary security** via SD-JWT selective disclosure (minimize what the agent sees). +- **Execution boundary security** via OS sandboxing (minimize what the agent can do). +- **Co-signed receipts** recording property references and enforcement proof, never values. + +--- + +## 2. Conventions and Terminology + +The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", +"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", +and "OPTIONAL" in this document are to be interpreted as described +in BCP 14 [RFC 2119] [RFC 8174] when, and only when, they appear +in all capitals, as shown here. + +### 2.1. Definitions + +**Principal:** A human user who holds the root keypair and is the +ultimate authority over all agent actions taken on their behalf. + +**Orchestrator:** An agent that holds the root mandate from the +principal. The orchestrator is the only agent that MAY hold the +principal's full context. It delegates scoped mandates to downstream +agents. + +**Mandate:** A signed authorization object that specifies what an +agent is permitted to do, what context it may disclose, and when +the authorization expires. + +**Mandate Chain:** An ordered sequence of mandates from root to +leaf, each cryptographically linked to its parent. + +**Scope:** The set of actions a mandate permits. Deny-by-default: +an empty scope permits nothing. + +**Disclosure Set:** The set of context classes an agent holds and +the conditions under which they may be shared. + +**Capability Token:** A single-use, signed authorization to open a +session with a specific agent for a specific action. + +**Session DID:** An ephemeral `did:key` identifier generated for a +single session and discarded at session close. + +**Receipt:** A co-signed record of a transaction that contains +property type references but never property values. + +**Decay State:** The lifecycle state of a mandate as it approaches +or passes its TTL without renewal. + +--- + +## 3. Trust Model and Threat Model + +### 3.1. Trust Hierarchy + +The PAP trust hierarchy is: + +``` +Human Principal (device-bound keypair, root of trust) + +-- Orchestrator Agent (root mandate, full principal context) + +-- Downstream Agent (task mandate, scoped context) + +-- Marketplace Agent (own principal chain) +``` + +The principal's device-bound keypair is the sole root of trust. +Every agent in a transaction MUST carry a cryptographically +verifiable mandate chain traceable to this root. + +### 3.2. Trust Assumptions + +| Assumption | Verification Method | +|---|---| +| Principal keypair not compromised | WebAuthn device binding (Section 4.3) | +| Orchestrator delegates correctly | Mandate chain verification (Section 5.6) | +| Session keys not leaked | Single-use per session, discarded at close | +| Clocks approximately synchronized | RFC 3339 timestamps; receivers SHOULD reject tokens with skew exceeding implementation-defined thresholds | +| Ed25519 not broken | Cryptographic library security; algorithm agility reserved for future versions | + +### 3.3. Threat Model + +PAP is designed to defend against the following threats: + +**T1. Context profiling.** An adversary correlates a principal's +transactions across sessions to build a behavioral profile. +*Mitigation:* Ephemeral session DIDs (Section 6.3) ensure each +session is cryptographically unlinkable. + +**T2. Over-disclosure.** An agent discloses more principal context +than the principal authorized. *Mitigation:* SD-JWT selective +disclosure (Section 7) structurally prevents disclosure of claims +not included in the disclosure set. Marketplace filtering +(Section 9.3) excludes agents whose requirements exceed the +mandate before any session is established. + +**T3. Delegation bypass.** A downstream agent acts outside its +delegated scope. *Mitigation:* Scope containment (Section 5.4) and +TTL bounds (Section 5.5) are verified cryptographically at each +level of the mandate chain. + +**T4. Replay attacks.** An adversary replays a captured capability +token to open an unauthorized session. *Mitigation:* Nonce +consumption (Section 6.2) ensures each token is single-use. + +**T5. Mandate tampering.** An adversary modifies a mandate in the +chain. *Mitigation:* Parent hash binding (Section 5.3) and Ed25519 +signatures (Section 5.2) detect any modification. + +**T6. Platform capture.** A platform operator accumulates control +over agent transactions through infrastructure dependency. +*Mitigation:* Federated discovery (Section 10), no central +registry, no token economy, principal-held keys. Marketplace +registries MUST NOT rank query results by operator metrics +(Section 9.6) — ranking power is platform capture power. Trust +evaluation is the principal's responsibility. + +**T7. Payment linkability.** A payment is correlated with the +principal's identity. *Mitigation:* Chaumian ecash blind-signed +tokens (Section 13.1) provide unlinkable proof of value transfer. + +### 3.4. Explicit Non-Goals + +The following are explicitly out of scope for PAP: + +1. Compatibility with token economy monetization. +2. Enclave-as-equivalent-to-local trust models. +3. Identity recovery through platform operators. +4. Central registries for agent discovery. +5. Runtime scope expansion of mandates. +6. Arbitrary code execution in the orchestrator context. +7. Any extension that trades trust guarantees for adoption ease. + +--- + +## 4. Identity Layer + +### 4.1. DID Method + +PAP uses the `did:key` method as defined in [DID-KEY]. All +identifiers MUST use Ed25519 public keys with the following +derivation: + +``` +did:key:z +``` + +Where: +- `0xed01` is the multicodec prefix for Ed25519 public keys. +- `public_key_bytes` is the 32-byte Ed25519 public key. +- `base58btc` is Bitcoin's base58 encoding. +- The `z` prefix indicates base58btc multibase encoding. + +Implementations MUST support `did:key` resolution by extracting +the public key bytes from the DID string: + +1. Strip the `did:key:z` prefix. +2. Base58-decode the remainder. +3. Verify the first two bytes are `0xed` and `0x01`. +4. The remaining 32 bytes are the Ed25519 public key. + +### 4.2. DID Document + +A DID document for a PAP identity MUST conform to [DID-CORE] and +contain: + +```json +{ + "@context": "https://www.w3.org/ns/did/v1", + "id": "did:key:z...", + "verificationMethod": [{ + "id": "did:key:z...#key-1", + "type": "Ed25519VerificationKey2020", + "controller": "did:key:z...", + "publicKeyMultibase": "z" + }], + "authentication": ["did:key:z...#key-1"] +} +``` + +A DID document MUST NOT contain any personal information. It +contains only the public key and verification method reference. + +### 4.3. Principal Keypair + +The principal keypair is the root of trust. It MUST be an Ed25519 +keypair. In production deployments, the private key SHOULD be +bound to a hardware authenticator via WebAuthn [WEBAUTHN]. + +Implementations MUST support the `PrincipalSigner` interface: + +- `did() -> String` -- The `did:key` identifier. +- `sign(message: bytes) -> bytes` -- Ed25519 signature (64 bytes). +- `verifying_key() -> Ed25519PublicKey` -- The public key. + +Implementations MAY use software keys for development and testing. +Production deployments SHOULD use WebAuthn-backed keys. + +### 4.4. Session Keypair + +A session keypair is an ephemeral Ed25519 keypair generated fresh +for each protocol session. Session keypairs: + +- MUST be generated using a cryptographically secure random number + generator. +- MUST NOT be derived from or linked to the principal keypair. +- MUST be discarded when the session closes. +- MUST NOT be persisted to stable storage. + +The session DID is derived using the same `did:key` method as the +principal DID. An observer MUST NOT be able to determine whether a +`did:key` identifier represents a principal or a session key. + +--- + +## 5. Mandate Structure and Delegation Rules + +### 5.1. Mandate Object + +A mandate is the core delegation primitive. It authorizes an agent +to perform specific actions with specific context. A mandate MUST +contain the following fields: + +| Field | Type | Required | Description | +|---|---|---|---| +| `principal_did` | String | REQUIRED | DID of the human principal (root of trust) | +| `agent_did` | String | REQUIRED | DID of the agent receiving this mandate | +| `issuer_did` | String | REQUIRED | DID of the entity signing this mandate | +| `parent_mandate_hash` | String or null | REQUIRED | SHA-256 hash of the parent mandate, or null for root mandates | +| `scope` | Scope | REQUIRED | Permitted actions (Section 5.4) | +| `disclosure_set` | DisclosureSet | REQUIRED | Context classes and sharing conditions (Section 5.4.3) | +| `ttl` | DateTime | REQUIRED | Expiry timestamp (RFC 3339) | +| `decay_state` | DecayState | REQUIRED | Current lifecycle state (Section 5.7) | +| `issued_at` | DateTime | REQUIRED | Issuance timestamp (RFC 3339) | +| `payment_proof` | PaymentProof or null | OPTIONAL | ZK payment commitment (Section 13.1) | +| `signature` | String or null | OPTIONAL | Ed25519 signature (base64url-no-pad) | + +### 5.2. Mandate Signing + +A mandate MUST be signed by the issuer's Ed25519 signing key. + +The canonical form for signing MUST be computed as follows: + +1. Construct a JSON object containing all mandate fields EXCEPT + `signature`. +2. DateTime fields MUST be serialized as RFC 3339 strings. +3. Null fields MUST be included as JSON `null`. +4. Serialize the JSON object to bytes. +5. Compute the Ed25519 signature over these bytes. +6. Encode the 64-byte signature using base64url without padding + (RFC 4648 Section 5, no `=` padding). + +The canonical JSON object MUST contain exactly these keys: + +```json +{ + "principal_did": "...", + "agent_did": "...", + "issuer_did": "...", + "parent_mandate_hash": null, + "scope": { ... }, + "disclosure_set": { ... }, + "ttl": "2026-03-15T20:00:00+00:00", + "issued_at": "2026-03-15T16:00:00+00:00", + "payment_proof": null +} +``` + +### 5.3. Mandate Hashing + +The mandate hash is used for parent-child linking in delegation +chains. It MUST be computed as: + +1. Compute the canonical form (Section 5.2, step 1-4). +2. Apply SHA-256 to the canonical bytes. +3. Encode the 32-byte digest using base64url without padding. + +The hash MUST be deterministic: the same mandate MUST always +produce the same hash. + +### 5.4. Scope + +#### 5.4.1. Scope Object + +A scope defines the set of permitted actions. It is deny-by-default: +an agent with an empty scope MUST NOT perform any action. + +```json +{ + "actions": [ + { + "action": "schema:SearchAction", + "object": "schema:WebPage", + "conditions": {} + } + ] +} +``` + +| Field | Type | Required | Description | +|---|---|---|---| +| `actions` | Array of ScopeAction | REQUIRED | The permitted actions | + +#### 5.4.2. ScopeAction Object + +| Field | Type | Required | Description | +|---|---|---|---| +| `action` | String | REQUIRED | Schema.org action type (e.g., `schema:SearchAction`) | +| `object` | String or null | OPTIONAL | Schema.org object type constraint (e.g., `schema:Flight`) | +| `conditions` | Object | OPTIONAL | Protocol-level conditions (key-value pairs). Default: empty object. | + +Action and object type references MUST use the `schema:` prefix +for Schema.org vocabulary. Implementations MAY define additional +namespaced prefixes for domain-specific vocabularies. + +#### 5.4.3. DisclosureSet Object + +The disclosure set defines what context an agent holds and the +conditions for sharing it. + +```json +{ + "entries": [ + { + "type": "schema:Person", + "permitted_properties": ["schema:name", "schema:nationality"], + "prohibited_properties": ["schema:email", "schema:telephone"], + "session_only": true, + "no_retention": true + } + ] +} +``` + +| Field | Type | Required | Description | +|---|---|---|---| +| `entries` | Array of DisclosureEntry | REQUIRED | The disclosure entries | + +#### 5.4.4. DisclosureEntry Object + +| Field | Type | Required | Description | +|---|---|---|---| +| `type` | String | REQUIRED | Schema.org type (e.g., `schema:Person`) | +| `permitted_properties` | Array of String | REQUIRED | Properties the agent MAY disclose | +| `prohibited_properties` | Array of String | REQUIRED | Properties the agent MUST NOT disclose | +| `session_only` | Boolean | OPTIONAL | If true, disclosed data is valid only for the session duration. Default: false. | +| `no_retention` | Boolean | OPTIONAL | If true, the receiving party MUST NOT retain disclosed data beyond the session. Default: false. | + +Property references MUST use Schema.org property names with the +`schema:` prefix. + +**Property Reference Format:** When used in receipts or marketplace +advertisements, a fully qualified property reference is formed as +`{type}.{property}`, e.g., `schema:Person.schema:name`. + +#### 5.4.4.1. TEE Requirement for No-Retention Disclosures + +When a disclosure entry has `no_retention` set to true, the receiving +agent MUST provide TEE attestation (Section 13.6) during session +establishment. If the receiving agent cannot provide valid TEE +attestation, the initiating agent MUST NOT disclose properties from +that entry. + +Without TEE attestation, `no_retention` is a contractual constraint +only — the protocol cannot enforce data deletion on an untrusted host. +Implementations SHOULD clearly communicate this limitation to +principals when TEE attestation is unavailable. + +An implementation's disclosure validation MUST return one of three +states to the caller: + +| State | Meaning | +|---|---| +| `NotRequired` | No `no_retention` entries in the disclosure set | +| `TeeEnforced` | TEE attestation present; retention constraint is cryptographic | +| `ContractualOnly` | No TEE available; `no_retention` is a contractual term only | + +Implementations that support the TEE extension (Section 13.6) MUST +treat `ContractualOnly` as an error. Implementations without TEE +support MAY proceed with `ContractualOnly` but MUST expose this +state to the caller so the principal can make an informed decision. + +#### 5.4.5. Scope Containment + +A child scope S_c is **contained by** a parent scope S_p (written +S_c <= S_p) if and only if for every action A_c in S_c, there +exists an action A_p in S_p such that: + +1. `A_c.action == A_p.action` +2. If `A_p.object` is non-null, then `A_c.object` MUST equal + `A_p.object`. +3. If `A_p.object` is null, then `A_c.object` MAY be any value + (including null). +4. If `A_p.object` is non-null and `A_c.object` is null, the + containment check MUST fail. A child MUST NOT broaden an object + constraint. + +### 5.5. Delegation Rules + +When an agent delegates a mandate to a child agent, the following +rules MUST be enforced: + +**R1. Scope Containment:** The child mandate's scope MUST be +contained by the parent mandate's scope (Section 5.4.5). If +scope containment fails, the delegation MUST be rejected. + +**R2. TTL Bound:** The child mandate's `ttl` MUST NOT exceed the +parent mandate's `ttl`. If the child TTL exceeds the parent TTL, +the delegation MUST be rejected. + +**R3. Parent Hash Binding:** The child mandate's +`parent_mandate_hash` MUST equal the hash (Section 5.3) of the +parent mandate's canonical form. + +**R4. Issuer Chain:** The child mandate's `issuer_did` MUST equal +the parent mandate's `agent_did`. The child mandate MUST be signed +by the parent mandate's `agent_did` key. + +**R5. Principal Propagation:** The child mandate's `principal_did` +MUST equal the parent mandate's `principal_did`. + +**R6. Root Mandate:** A root mandate MUST have +`parent_mandate_hash` set to null. A root mandate's `issuer_did` +MUST equal its `principal_did`. + +### 5.6. Mandate Chain Verification + +A mandate chain is an ordered array of mandates `[M_0, M_1, ..., M_n]` +where `M_0` is the root mandate. Verification MUST proceed as follows: + +1. `M_0.parent_mandate_hash` MUST be null. +2. `M_0.signature` MUST verify against the principal's public key. +3. For each `i` from 1 to n: + a. `M_i.parent_mandate_hash` MUST equal `hash(M_{i-1})`. + b. `M_i.scope` MUST satisfy scope containment against + `M_{i-1}.scope` (Section 5.4.5). + c. `M_i.ttl` MUST NOT exceed `M_{i-1}.ttl`. + d. `M_i.signature` MUST verify against the public key of + `M_{i-1}.agent_did`. + +If any check fails, the entire chain MUST be rejected. + +### 5.7. Decay State Machine + +A mandate's decay state tracks its lifecycle as the TTL progresses. +The decay state MUST be one of: + +| State | Description | +|---|---| +| `Active` | Full scope, within TTL | +| `Degraded` | Reduced scope, TTL within decay window, renewal pending | +| `ReadOnly` | No execution permitted, observation only, TTL expired | +| `Suspended` | No activity, awaiting principal review | + +#### 5.7.1. State Transitions + +The following transitions are valid: + +``` +Active --> Degraded --> ReadOnly --> Suspended + ^ | | + | | | + +-- renewal -+-- renewal -+ +``` + +| From | To | Condition | +|---|---|---| +| Active | Degraded | Remaining TTL <= implementation-defined decay window | +| Degraded | ReadOnly | TTL expired without renewal | +| ReadOnly | Suspended | Implementation-defined timeout without principal action | +| Degraded | Active | Mandate renewed by issuer | +| ReadOnly | Active | Mandate renewed by issuer | +| Suspended | (none) | Suspended mandates MUST NOT be renewed. Principal MUST issue a new mandate. | + +Any transition not listed above MUST be rejected. + +#### 5.7.2. Decay Computation + +An implementation SHOULD compute the current decay state as: + +``` +function compute_decay_state(mandate, decay_window_seconds): + now = current_utc_time() + if now > mandate.ttl: + if mandate.decay_state == Suspended: + return Suspended + else: + return ReadOnly + else: + remaining = mandate.ttl - now (in seconds) + if remaining <= decay_window_seconds: + return Degraded + else: + return Active +``` + +The `decay_window_seconds` parameter is implementation-defined. +Implementations SHOULD document their chosen value. + +--- + +## 6. Session Lifecycle + +### 6.1. Session State Machine + +A session tracks the state of a transaction between two agents. +The session state MUST be one of: + +| State | Description | +|---|---| +| `Initiated` | Capability token presented, awaiting verification | +| `Open` | Handshake complete, session DIDs exchanged | +| `Executed` | Transaction executed within session | +| `Closed` | Session closed, ephemeral keys discarded | + +Valid transitions: + +``` +Initiated --> Open --> Executed --> Closed + | ^ + +----------> Closed (early) ------+ + ^ + Open -------> Closed (early) -----+ +``` + +| From | To | Trigger | +|---|---|---| +| Initiated | Open | Session DID exchange completed | +| Initiated | Closed | Early termination (rejection or error) | +| Open | Executed | Action executed | +| Open | Closed | Early termination | +| Executed | Closed | Session close message sent | + +Any transition not listed above MUST be rejected. + +### 6.2. Capability Token + +A capability token is a single-use authorization to open a session. +It MUST contain the following fields: + +| Field | Type | Required | Description | +|---|---|---|---| +| `id` | String | REQUIRED | Unique token identifier (UUID v4) | +| `target_did` | String | REQUIRED | DID of the agent this token authorizes a session with | +| `action` | String | REQUIRED | Schema.org action type this token authorizes | +| `nonce` | String | REQUIRED | Single-use nonce (UUID v4), consumed on session initiation | +| `issuer_did` | String | REQUIRED | DID of the issuing agent (typically the orchestrator) | +| `issued_at` | DateTime | REQUIRED | Issuance timestamp (RFC 3339) | +| `expires_at` | DateTime | REQUIRED | Expiry timestamp (RFC 3339) | +| `signature` | String or null | OPTIONAL | Ed25519 signature (base64url-no-pad) | + +#### 6.2.1. Token Signing + +The token canonical form MUST be: + +```json +{ + "id": "...", + "target_did": "...", + "action": "...", + "nonce": "...", + "issuer_did": "...", + "issued_at": "...", + "expires_at": "..." +} +``` + +Signing follows the same procedure as mandate signing (Section 5.2). + +#### 6.2.2. Token Verification + +A receiving agent MUST verify a capability token as follows: + +1. `token.target_did` MUST match the receiver's DID. +2. `token.nonce` MUST NOT appear in the receiver's consumed nonce + set. +3. The current time MUST NOT exceed `token.expires_at`. +4. `token.signature` MUST verify against the public key of + `token.issuer_did`. + +If all checks pass, the receiver MUST immediately add `token.nonce` +to its consumed nonce set. A nonce, once consumed, MUST never be +accepted again. + +### 6.3. Six-Phase Handshake + +The session handshake consists of six phases. Each phase involves +a message exchange between the initiating agent (I) and the +receiving agent (R). + +``` +Phase Direction Message Data +----- --------- ------------------- -------------------------------- +1a I -> R TokenPresentation CapabilityToken +1b R -> I TokenAccepted session_id, receiver_session_did + R -> I TokenRejected reason (terminates handshake) + +2a I -> R SessionDidExchange initiator_session_did +2b R -> I SessionDidAck (empty) + +3a I -> R DisclosureOffer disclosures (may be empty array) +3b R -> I DisclosureAccepted (empty) + +4 R -> I ExecutionResult result (Schema.org JSON-LD) + +5a I -> R ReceiptForCoSign half-signed TransactionReceipt +5b R -> I ReceiptCoSigned fully co-signed TransactionReceipt + +6a I -> R SessionClose session_id +6b R -> I SessionClosed (empty) +``` + +#### 6.3.1. Phase 1: Token Presentation + +The initiating agent presents a signed capability token. The +receiving agent verifies the token (Section 6.2.2). + +On acceptance, the receiver MUST: +1. Generate a fresh session keypair (Section 4.4). +2. Create a session in the `Initiated` state. +3. Return a `TokenAccepted` message containing the session ID and + the receiver's ephemeral session DID. + +On rejection, the receiver MUST return a `TokenRejected` message +with a reason string. The handshake terminates. + +#### 6.3.2. Phase 2: Ephemeral DID Exchange + +The initiating agent generates its own fresh session keypair and +sends a `SessionDidExchange` message containing its session DID. + +On receipt, the receiver MUST: +1. Transition the session state from `Initiated` to `Open`. +2. Store the initiator's session DID. +3. Return a `SessionDidAck` message. + +After Phase 2, both parties have exchanged ephemeral session DIDs. +All subsequent envelope signatures (Section 8.2) MUST use session +keys. + +#### 6.3.3. Phase 3: Disclosure + +The initiating agent sends a `DisclosureOffer` containing an array +of SD-JWT disclosures (Section 7). The array MAY be empty for +zero-disclosure sessions. + +The receiver MUST: +1. Verify each disclosure against the SD-JWT commitment + (Section 7.3). +2. Return a `DisclosureAccepted` message. + +If disclosure verification fails, the receiver SHOULD return an +`Error` message and close the session. + +#### 6.3.4. Phase 4: Execution + +The receiver executes the requested action and returns an +`ExecutionResult` message containing a Schema.org JSON-LD result +object. + +The session state MUST transition from `Open` to `Executed`. + +#### 6.3.5. Phase 5: Receipt Co-Signing + +The initiating agent constructs a `TransactionReceipt` +(Section 11), signs it with its session key, and sends it as +`ReceiptForCoSign`. + +The receiving agent MUST: +1. Verify the initiator's signature on the receipt. +2. Add its own co-signature using its session key. +3. Return the fully co-signed receipt as `ReceiptCoSigned`. + +#### 6.3.6. Phase 6: Session Close + +Either party MAY initiate session close by sending a +`SessionClose` message containing the session ID. + +On receipt of `SessionClose`, the other party MUST: +1. Return a `SessionClosed` message. +2. Transition the session state to `Closed`. +3. Discard all ephemeral session keys. + +After Phase 6, both parties MUST discard their session keypairs. +Session DIDs MUST NOT be reused. + +--- + +## 7. SD-JWT Disclosure Protocol + +### 7.1. Overview + +PAP uses Selective Disclosure JWT (SD-JWT) as defined in +[SD-JWT-08] for context disclosure during the session handshake. +SD-JWT allows the principal to hold multiple claims but disclose +only those permitted by the mandate. + +### 7.2. SD-JWT Object + +An SD-JWT MUST contain: + +| Field | Type | Required | Description | +|---|---|---|---| +| `issuer` | String | REQUIRED | DID of the claim issuer (typically the principal) | +| `claims` | Object | REQUIRED (private) | All claims as key-value pairs | +| `salts` | Object | REQUIRED (private) | Per-claim random salts (UUID v4) | +| `signature` | String or null | OPTIONAL | Ed25519 signature over commitment bytes (base64url-no-pad) | + +The `claims` and `salts` fields are private to the holder and +MUST NOT be transmitted in their entirety. Only selected +disclosures (Section 7.3) are transmitted. + +### 7.3. Disclosure Object + +A disclosure reveals a single claim. It MUST contain: + +| Field | Type | Required | Description | +|---|---|---|---| +| `salt` | String | REQUIRED | The claim-specific random salt | +| `key` | String | REQUIRED | The claim key | +| `value` | Any JSON value | REQUIRED | The claim value | + +### 7.4. Commitment Computation + +The SD-JWT commitment is signed to bind all possible disclosures. + +1. For each claim `(key, value)` with salt `s`: + - Construct: `{"salt": s, "key": key, "value": value}` + - Hash: `SHA-256(JSON_bytes(disclosure))` + - Encode: base64url-no-pad + +2. Collect all hashes and sort lexicographically. + +3. Construct commitment bytes: + ```json + { + "issuer": "", + "disclosure_hashes": ["", "", ...] + } + ``` + +4. Sign: `Ed25519_sign(JSON_bytes(commitment))` + +### 7.5. Disclosure Verification + +A verifier MUST: + +1. Verify the SD-JWT signature over the commitment bytes using the + issuer's public key. +2. For each received disclosure: + a. Compute `hash = base64url(SHA-256(JSON_bytes(disclosure)))`. + b. Verify that `hash` is present in the signed + `disclosure_hashes` array. + +If any disclosure hash is not found in the commitment, the +verification MUST fail. + +### 7.6. Zero-Disclosure Sessions + +A session MAY proceed with zero disclosures. In this case: + +- The `DisclosureOffer` message carries an empty disclosures array. +- The SD-JWT signature MUST still verify (the commitment contains + hashes for all claims, but none are revealed). +- The receiver MUST accept an empty disclosure set without error. + +--- + +## 8. Protocol Messages and Envelope + +### 8.1. Protocol Message Types + +All protocol messages are serialized as JSON objects with a `type` +discriminator field. The following message types are defined: + +| Type | Phase | Direction | Fields | +|---|---|---|---| +| `TokenPresentation` | 1 | I->R | `token`: CapabilityToken | +| `TokenAccepted` | 1 | R->I | `session_id`: String, `receiver_session_did`: String | +| `TokenRejected` | 1 | R->I | `reason`: String | +| `SessionDidExchange` | 2 | I->R | `initiator_session_did`: String | +| `SessionDidAck` | 2 | R->I | (no fields) | +| `DisclosureOffer` | 3 | I->R | `disclosures`: Array of JSON values | +| `DisclosureAccepted` | 3 | R->I | (no fields) | +| `ExecutionResult` | 4 | R->I | `result`: JSON value (Schema.org JSON-LD) | +| `ReceiptForCoSign` | 5 | I->R | `receipt`: TransactionReceipt | +| `ReceiptCoSigned` | 5 | R->I | `receipt`: TransactionReceipt | +| `SessionClose` | 6 | Either | `session_id`: String | +| `SessionClosed` | 6 | Either | (no fields) | +| `Error` | Any | Either | `code`: String, `message`: String | + +### 8.2. Envelope + +Protocol messages are transmitted inside an envelope that provides +routing, sequencing, and integrity. + +| Field | Type | Required | Description | +|---|---|---|---| +| `id` | String | REQUIRED | Unique envelope identifier (UUID v4) | +| `session_id` | String | REQUIRED | Session this envelope belongs to | +| `sender` | String | REQUIRED | DID of the sender | +| `recipient` | String | REQUIRED | DID of the intended recipient | +| `sequence` | Integer | REQUIRED | Monotonically increasing sequence number within the session | +| `payload` | ProtocolMessage | REQUIRED | The protocol message | +| `timestamp` | DateTime | REQUIRED | ISO 8601 timestamp | +| `signature` | Bytes or null | OPTIONAL | Ed25519 signature over signable bytes | + +#### 8.2.1. Envelope Signing + +The signable bytes for an envelope MUST be computed as: + +``` +SHA-256(session_id_bytes || sequence_big_endian_8_bytes || payload_json_bytes) +``` + +Where `||` denotes concatenation and `sequence_big_endian_8_bytes` +is the sequence number as an 8-byte big-endian integer. + +Before Phase 2 (DID exchange), the `signature` field MAY be null +because the capability token carries its own signature from the +issuer. + +After Phase 2, all envelopes MUST be signed by the sender's +ephemeral session key. + +#### 8.2.2. Envelope Verification + +The recipient MUST: + +1. Verify `recipient` matches its own DID. +2. Verify `sequence` is strictly greater than the last received + sequence number for this session. +3. If `signature` is present, verify it against the sender's + session public key. + +--- + +## 9. Marketplace Advertisement Schema + +### 9.1. Agent Advertisement + +An agent advertisement declares an agent's capabilities, disclosure +requirements, and return types. Advertisements use Schema.org +vocabulary and JSON-LD structure. + +| Field | Type | Required | Description | +|---|---|---|---| +| `@context` | String | REQUIRED | MUST be `"https://schema.org"` | +| `@type` | String | REQUIRED | MUST be `"schema:Service"` | +| `name` | String | REQUIRED | Human-readable agent name | +| `provider` | Provider | REQUIRED | Provider organization (Section 9.2) | +| `capability` | Array of String | REQUIRED | Schema.org action types the agent can perform | +| `object_types` | Array of String | REQUIRED | Schema.org object types the agent operates on | +| `requires_disclosure` | Array of String | REQUIRED | Fully qualified property references the agent requires (e.g., `schema:Person.name`) | +| `returns` | Array of String | REQUIRED | Schema.org types the agent returns | +| `ttl_min` | Integer | OPTIONAL | Minimum session TTL in seconds. Default: 300. | +| `signed_by` | String | REQUIRED | DID that signed this advertisement | +| `signature` | String or null | OPTIONAL | Ed25519 signature (base64url-no-pad) | + +### 9.2. Provider Object + +| Field | Type | Required | Description | +|---|---|---|---| +| `@type` | String | REQUIRED | MUST be `"schema:Organization"` | +| `name` | String | REQUIRED | Organization name | +| `did` | String | REQUIRED | Operator DID | + +### 9.3. Disclosure Filtering + +A marketplace registry MUST support two query modes: + +**Query by action:** Return all advertisements whose `capability` +array contains the requested action type. + +**Query by action with disclosure satisfiability:** Return only +advertisements where: +1. The `capability` array contains the requested action type, AND +2. Every entry in `requires_disclosure` is present in the caller's + available properties list. + +This filtering MUST occur before any mandate is issued or session +is established. Agents whose disclosure requirements exceed the +principal's authorization MUST be excluded. The principal MUST +NOT be asked to over-disclose. + +### 9.4. Advertisement Signing + +The canonical form for advertisement signing MUST include all +fields except `signature`: + +```json +{ + "@context": "https://schema.org", + "@type": "schema:Service", + "name": "...", + "provider": { ... }, + "capability": [...], + "object_types": [...], + "requires_disclosure": [...], + "returns": [...], + "ttl_min": 300, + "signed_by": "did:key:z..." +} +``` + +Signing follows the same Ed25519/base64url-no-pad procedure as +mandate signing (Section 5.2). + +A marketplace registry MUST reject unsigned advertisements. + +### 9.5. Advertisement Hashing + +The content hash of an advertisement MUST be computed as: + +``` +base64url(SHA-256(canonical_bytes)) +``` + +This hash is used for deduplication in federated registries +(Section 10). + +### 9.6. Operator Metrics + +An agent advertisement MAY include an `operator_metrics` field +containing self-reported operational statistics. Metrics are +informational metadata for principal evaluation and MUST NOT be +used by marketplace registries for ranking, sorting, or filtering +query results. + +| Field | Type | Required | Description | +|---|---|---|---| +| `total_receipts` | Integer | OPTIONAL | Total co-signed transaction receipts | +| `bilateral_attestations` | Integer | OPTIONAL | Receipts with bilateral session attestation | +| `unique_counterparties` | Integer | OPTIONAL | Distinct counterparty session DIDs | +| `action_types` | Array of String | OPTIONAL | Distinct Schema.org action types performed | +| `tee_sessions_pct` | Number | OPTIONAL | Fraction of sessions with TEE attestation (0.0 to 1.0) | +| `first_seen` | DateTime | OPTIONAL | RFC 3339 timestamp of first registration | +| `uptime_days` | Integer | OPTIONAL | Days the operator has been active | + +The `operator_metrics` field MUST be excluded from the advertisement +content hash (Section 9.5) and signature computation (Section 9.4). +Metrics change over time while the advertisement identity remains +stable. + +**Anti-ranking requirement:** Marketplace registries MUST return +query results in insertion order. Registries MUST NOT rank, sort, +or filter results based on operator metrics. The principal's +orchestrator is responsible for evaluating metrics and making +selection decisions. This requirement prevents marketplace +registries from accumulating ranking power, which would constitute +platform capture. + +--- + +## 10. Federation Protocol + +### 10.1. Overview + +Federation enables independent marketplace registries to discover +and share agent advertisements. Federation is peer-to-peer with +no central coordinator. + +### 10.2. Registry Peer + +A federation peer is identified by: + +| Field | Type | Required | Description | +|---|---|---|---| +| `did` | String | REQUIRED | DID of the peer registry operator | +| `endpoint` | String | REQUIRED | HTTP(S) endpoint for federation API calls | +| `last_sync` | DateTime or null | OPTIONAL | Timestamp of last successful sync | + +### 10.3. Federation Messages + +Federation uses the following message types, discriminated by a +`type` field: + +| Type | Direction | Fields | Description | +|---|---|---|---| +| `QueryByAction` | Request | `action`: String | Query for agents supporting an action | +| `QueryResponse` | Response | `advertisements`: Array of AgentAdvertisement | Matching advertisements | +| `Announce` | Request | `advertisement`: AgentAdvertisement | Announce a new local advertisement | +| `AnnounceAck` | Response | `hash`: String, `accepted`: Boolean | Acknowledge announcement | +| `PeerList` | Request | (none) | Request known peer list | +| `PeerListResponse` | Response | `peers`: Array of RegistryPeer | Known peers | + +### 10.4. Federation Endpoints + +A federation server MUST expose the following HTTP endpoints: + +| Method | Path | Request Body | Response Body | +|---|---|---|---| +| GET | `/federation/query?action={action}` | (none) | `QueryResponse` | +| POST | `/federation/announce` | `Announce` | `AnnounceAck` | +| GET | `/federation/peers` | (none) | `PeerListResponse` | + +### 10.5. Content-Hash Deduplication + +When merging remote advertisements, a federated registry MUST: + +1. Compute the content hash of each advertisement (Section 9.5). +2. If the hash already exists in the local seen-hashes set, skip + the advertisement. +3. If the advertisement has no signature, skip it. +4. Otherwise, register the advertisement and add its hash to the + seen-hashes set. + +This ensures idempotent synchronization and prevents duplicate +entries. + +### 10.6. Peer Discovery + +A registry MAY discover new peers transitively: + +1. Query a known peer's `/federation/peers` endpoint. +2. For each peer in the response not already known, add it to the + local peer list. + +Implementations SHOULD implement rate limiting and SHOULD validate +that newly discovered peers are reachable before adding them. + +### 10.7. Peer Trust Signals + +A federation peer MAY present trust signals to establish +credibility with other registries. Trust signals are additive — +more signals increase confidence but no single signal is +sufficient alone. + +#### 10.7.1. Signal Categories + +| Signal | Weight | Description | +|---|---|---| +| Social vouching | Primary | Signed vouches from existing peers | +| TEE attestation | Supplementary | Hardware attestation of registry software | +| Operational history | Supplementary | Observable uptime and sync metrics | +| Domain verification | Supplementary | DNS or TLS proof of domain ownership | + +A registry SHOULD require at least two signal categories before +granting a peer full synchronization privileges. + +#### 10.7.2. Peer Vouch + +A peer vouch is a signed statement by an existing peer that they +have evaluated the new peer and believe it operates a conformant +registry. + +| Field | Type | Required | Description | +|---|---|---|---| +| `voucher_did` | String | REQUIRED | DID of the vouching peer | +| `vouchee_did` | String | REQUIRED | DID of the peer being vouched | +| `timestamp` | DateTime | REQUIRED | RFC 3339 timestamp | +| `justification` | String | REQUIRED | Structured reason for vouching | +| `signature` | String | REQUIRED | Ed25519 signature by voucher | + +#### 10.7.3. Vouch Budget + +To prevent vouch ring attacks (where colluding peers mutually +vouch to create Sybil identities), implementations SHOULD enforce: + +- **Vouch budget:** Each peer MAY issue at most 3 vouches per year. +- **Minimum age:** A peer MUST be registered for at least 90 days + before it is eligible to vouch for others. +- **Probationary period:** Newly registered peers operate in + probationary status for 60 days. During probation, a peer MAY + receive advertisements but MUST NOT vouch for other peers. +- **Diverse trust paths:** The vouchers for a new peer SHOULD NOT + all trace their own vouching chains through the same set of + peers. + +--- + +## 11. Receipt Format + +### 11.1. Transaction Receipt + +A transaction receipt is a co-signed record of a completed session. +Receipts contain property type references only -- never values. + +| Field | Type | Required | Description | +|---|---|---|---| +| `session_id` | String | REQUIRED | Ephemeral session ID (not linked to principal) | +| `action` | String | REQUIRED | Schema.org action type executed | +| `initiating_agent_did` | String | REQUIRED | Ephemeral session DID of the initiator | +| `receiving_agent_did` | String | REQUIRED | Ephemeral session DID of the receiver | +| `disclosed_by_initiator` | Array of String | REQUIRED | Property references disclosed by the initiator | +| `disclosed_by_receiver` | Array of String | REQUIRED | Property references or operator statements from the receiver | +| `executed` | String | REQUIRED | Human-readable description of the action executed | +| `returned` | String | REQUIRED | Human-readable description of the result returned | +| `timestamp` | DateTime | REQUIRED | RFC 3339 timestamp | +| `signatures` | Array of String | REQUIRED | Co-signatures (base64url-no-pad) | + +### 11.2. Receipt Signing + +The canonical form for receipt signing MUST include all fields +except `signatures`: + +```json +{ + "session_id": "...", + "action": "...", + "initiating_agent_did": "...", + "receiving_agent_did": "...", + "disclosed_by_initiator": [...], + "disclosed_by_receiver": [...], + "executed": "...", + "returned": "...", + "timestamp": "..." +} +``` + +### 11.3. Co-Signing Protocol + +1. The initiator constructs a receipt from the completed session. +2. The initiator computes `Ed25519_sign(canonical_bytes)` using its + session key and appends the base64url-no-pad encoded signature + to `signatures`. +3. The initiator sends the half-signed receipt to the receiver. +4. The receiver verifies the initiator's signature against the + initiator's session public key. +5. The receiver computes `Ed25519_sign(canonical_bytes)` using its + session key and appends its signature to `signatures`. +6. The receiver returns the fully co-signed receipt. + +### 11.4. Receipt Verification + +To verify a co-signed receipt: + +1. The `signatures` array MUST contain exactly 2 entries. +2. `signatures[0]` MUST verify against the initiator's session + public key. +3. `signatures[1]` MUST verify against the receiver's session + public key. + +### 11.5. Privacy Properties + +Receipts MUST NOT contain: +- Personal data values (names, emails, etc.) +- SD-JWT claim values +- Raw execution inputs or outputs + +Receipts MUST contain only: +- Schema.org property type references (e.g., + `schema:Person.schema:name`) +- Operator-defined category references (e.g., + `operator:search_executed`) +- Human-readable action/result descriptions + +This ensures receipts are auditable by both principals without +revealing the data exchanged in the transaction. + +### 11.6. Session Attestation + +A session attestation is a signed statement by a session +participant recording their assessment of the session outcome. + +| Field | Type | Required | Description | +|---|---|---|---| +| `session_id` | String | REQUIRED | Session identifier | +| `attester_did` | String | REQUIRED | Ephemeral session DID of attester | +| `outcome` | String | REQUIRED | One of: `fulfilled`, `partial`, `failed`, `disputed` | +| `action_type` | String | REQUIRED | Schema.org action type executed | +| `timestamp` | DateTime | REQUIRED | RFC 3339 timestamp | +| `signature` | String | REQUIRED | Ed25519 signature by attester | + +A receipt with attestations from both the initiating and receiving +agents is **bilaterally attested**. Bilaterally attested receipts +carry higher evidentiary weight for operator metric computation. + +Attestations are per-action-type. An operator's reputation in one +action domain (e.g., `schema:SearchAction`) MUST NOT be conflated +with reputation in another domain (e.g., `schema:ReserveAction`). + +--- + +## 12. Verifiable Credential Envelope + +### 12.1. Overview + +PAP mandates MAY be wrapped in a W3C Verifiable Credential (VC) +envelope for interoperability with existing credential ecosystems. +The VC envelope is OPTIONAL; implementations MUST support bare +mandates and MAY additionally support VC-wrapped mandates. + +### 12.2. VC Structure + +A PAP Verifiable Credential MUST conform to [VC-DATA-MODEL-2.0]: + +```json +{ + "@context": [ + "https://www.w3.org/ns/credentials/v2", + "https://www.w3.org/ns/credentials/examples/v2" + ], + "id": "urn:uuid:", + "type": ["VerifiableCredential", "PAPMandateCredential"], + "issuer": "", + "issuanceDate": "", + "expirationDate": "", + "credentialSubject": { }, + "proof": { + "type": "Ed25519Signature2020", + "created": "", + "verificationMethod": "#key-1", + "proofPurpose": "assertionMethod", + "proofValue": "" + } +} +``` + +The `type` array MUST include both `"VerifiableCredential"` and +`"PAPMandateCredential"` for discoverability. + +### 12.3. Credential Signing + +The canonical form for VC signing MUST include all fields except +`proof`: + +```json +{ + "@context": [...], + "id": "...", + "type": [...], + "issuer": "...", + "issuanceDate": "...", + "expirationDate": "..." or null, + "credentialSubject": { ... } +} +``` + +The `proofValue` is `base64url(Ed25519_sign(JSON_bytes(canonical)))`. + +--- + +## 13. Extension Points + +The following extensions are defined for PAP v1.0. Core extensions +(Sections 13.1--13.4) were introduced in v0.4. Recovery mandates +(Section 13.5), TEE attestation (Section 13.6), and payment proof +validation (Section 13.7) were added in v0.7. All extensions are +OPTIONAL; a conformant implementation MAY support none, some, or +all of them. + +### 13.1. Payment Proof + +A mandate MAY carry a `payment_proof` field containing a +zero-knowledge payment commitment. PAP does not define the payment +protocol; it defines the integration point. Only cryptographic +commitments are stored — **never** amounts, destinations, mints, or +other identifying payment data. + +The `PaymentProof` type is a tagged enum with two variants: + +| Variant | Inner Type | Description | +|---|---|---| +| `Lightning` | `Bolt11Hash` | SHA-256 of a BOLT-11 invoice payment hash | +| `Ecash` | `CashuTokenHash` | SHA-256 of a Cashu blind-signed token | + +#### 13.1.1. Bolt11Hash + +A commitment to a Lightning Network payment. The `hash` field +contains the base64url-no-pad encoded SHA-256 of the BOLT-11 +invoice payment hash. The preimage is never stored. + +```json +{ + "type": "Lightning", + "hash": "" +} +``` + +#### 13.1.2. CashuTokenHash + +A commitment to a Cashu ecash token. The `hash` field contains the +base64url-no-pad encoded SHA-256 of the blind-signed token. The +token itself is never stored. + +```json +{ + "type": "Ecash", + "hash": "" +} +``` + +#### 13.1.3. Payment Proof Properties + +- The proof contains **only** a cryptographic commitment hash. +- No amounts, destinations, mints, or routing data are stored. +- The vendor MUST NOT be able to identify the payer from the proof. +- The proof MUST be unlinkable to the principal's identity. +- The payment proof is included in the mandate's canonical form for + signing. +- If a mandate's scope includes `schema:PayAction`, a payment proof + SHOULD be attached. Implementations MAY reject mandates that + permit payment actions without a proof. + +#### 13.1.4. Ecash Blind Signature Protocol + +PAP includes a reference implementation of the Chaumian blind signature +scheme in the `pap-ecash` crate. The scheme uses RFC 9474 +RSABSSA-SHA384-PSS (non-augmented variant, `randomize = false`). + +**Protocol parameters:** + +| Parameter | Value | +|---|---| +| Scheme | RSABSSA-SHA384-PSS (RFC 9474 §4.2, non-augmented) | +| Key size | ≥ 2048 bits (production); 1024 bits (tests only) | +| Commitment | SHA-256(`serial` ∥ `signature`), base64url-no-pad | +| Serial size | 32 bytes, randomly chosen by the client | + +**Protocol steps:** + +1. **Request** — client calls `ecash_request(serial, mint_pk)`. + Returns a `BlindToken` containing a randomly-blinded serial. Only the + `blinded_message()` bytes are transmitted to the mint. +2. **Mint** — mint calls `ecash_mint_sign(blinded_msg, keypair)`. + Returns raw blind-signature bytes to the client. +3. **Unblind** — client calls `ecash_unblind(blind_token, blind_sig, mint_pk)`. + Returns the spendable `EcashToken { serial, signature }`. +4. **Attach** — client calls `token.to_payment_proof()` and includes the + result in the mandate's `payment_proof` field. +5. **Verify** — payee calls `ecash_verify(token, mint_pk)`. Valid tokens + have a correct RSA-PSS signature over `serial`. +6. **Redeem** — payee calls `ecash_redeem(token, mint_pk, registry)`. + Atomically verifies and records `serial` in the spent registry, + preventing double-spend. + +**Unlinkability invariant:** The random blinding factor applied in step 1 +means that the `blinded_message` bytes transmitted to the mint are +statistically independent of the final `(serial, signature)` pair. The +mint cannot link a signing operation to a subsequent redemption. + +**Double-spend invariant:** `ecash_redeem` MUST return `EcashError::DoubleSpend` +on any second call with the same serial, regardless of signature validity. + +**Test vectors:** The conformance test suite is in `crates/pap-ecash/`. +Run the following to generate and verify all test vectors: + +```bash +cargo test -p pap-ecash -- --nocapture +``` + +The `ecash_test_vector` test uses a freshly-generated 1024-bit test key +(test-only size) and serial `0x000…001` (32 bytes). Because +`blind-rsa-signatures` v0.14 uses `OsRng` internally (no injectable RNG), +the blinding factor and PSS salt are non-deterministic. The test therefore +validates structural invariants (correct verification, 43-char base64url +commitment) rather than pinning an exact byte value. + +**C FFI:** `pap_ecash_mint_keypair_generate`, `pap_ecash_blind`, +`pap_ecash_blind_message_bytes`, `pap_ecash_mint_sign`, `pap_ecash_unblind`, +`pap_ecash_verify`, `pap_ecash_spent_registry_new`, `pap_ecash_redeem`, +`pap_ecash_token_payment_proof_commitment`. + +**WASM:** `EcashMintKeypair`, `EcashBlindToken`, `EcashToken`, +`ecashMintSign`, `ecashVerify`. + +### 13.2. Payment Proof Verification + +A receiving agent that requires payment MUST: +1. Extract the `payment_proof` from the mandate. +2. Validate the proof's structural integrity (valid base64url, + 32-byte SHA-256 commitment). +3. Verify the proof against the payment network (out of band): + - **Lightning**: verify the BOLT-11 payment hash preimage + - **Ecash**: verify the Cashu token with the issuing mint +4. Accept or reject the session based on verification. + +#### 13.2.1. Receipt Payment Proof Commitment + +When a transaction receipt is created for a `schema:PayAction`, +the receipt MUST include a `payment_proof_commitment` field +containing the commitment hash from the mandate's payment proof. +This enables auditing without revealing payment details. + +A receipt validator MUST check: +1. The `payment_proof_commitment` is present for payment actions. +2. The commitment matches the mandate's payment proof commitment. +3. The commitment is included in the receipt's canonical form for + co-signing. + +The verification protocol between the receiving agent and the +payment network is out of scope for this specification. + +### 13.3. Continuity Tokens + +A continuity token enables stateful relationships across sessions +without requiring the vendor to retain state. + +| Field | Type | Required | Description | +|---|---|---|---| +| `schema_type` | String | REQUIRED | Schema.org type describing the encrypted payload shape | +| `vendor_did` | String | REQUIRED | DID of the vendor that issued this token | +| `encrypted_payload` | String | REQUIRED | Vendor-encrypted state (opaque to orchestrator) | +| `ttl` | DateTime | REQUIRED | Expiry timestamp, set by the principal | +| `issued_at` | DateTime | REQUIRED | Issuance timestamp | + +#### 13.3.1. Continuity Token Lifecycle + +1. At session close, the vendor encrypts its internal state and + returns it as a continuity token to the orchestrator. +2. The orchestrator stores the token locally. The vendor retains + nothing. +3. When the principal returns, the orchestrator presents the token + to the vendor. +4. The vendor decrypts the payload and resumes the relationship. +5. The principal controls the TTL. The vendor MUST NOT set or + extend the TTL. +6. To sever the relationship, the principal deletes the token. No + revocation notice is required. + +#### 13.3.2. Continuity Token Properties + +- The `schema_type` MUST be inspectable by the orchestrator without + decrypting the payload. +- The vendor MUST NOT be able to write to the continuity token + without the principal presenting it. +- The encrypted payload format is vendor-defined and opaque to the + protocol. + +### 13.4. Auto-Approval Policies + +An auto-approval policy allows the principal to pre-authorize +certain categories of actions without per-transaction approval. + +| Field | Type | Required | Description | +|---|---|---|---| +| `name` | String | REQUIRED | Human-readable policy name | +| `scope` | Scope | REQUIRED | Subset of the mandate scope this policy applies to | +| `max_value` | Number or null | OPTIONAL | Maximum transaction value for auto-approval (currency-agnostic) | +| `zero_additional_disclosure` | Boolean | REQUIRED | If true, auto-approve only when zero additional disclosure is required beyond the mandate | +| `authored_at` | DateTime | REQUIRED | Timestamp when the principal authored this policy | + +#### 13.4.1. Auto-Approval Constraints + +- The policy scope MUST be contained by the mandate scope + (Section 5.4.5). A policy MUST NOT be more permissive than the + mandate. +- Policies are principal-authored and orchestrator-enforced. An + agent MUST NOT trigger a policy change by requesting it. +- `zero_additional_disclosure` defaults to true. When true, the + orchestrator MUST auto-approve only when the agent's disclosure + requirements are fully covered by the existing mandate. +- If `max_value` is set and the transaction value exceeds it, the + orchestrator MUST request explicit principal approval. + +### 13.5. M-of-N Social Recovery + +Principal identity recovery via a designated notary quorum. No central +recovery authority. The principal designates N notary DIDs at setup +time; any M co-signers from that set can authorize key rotation. + +#### 13.5.1. Recovery Mandate + +A principal creates a `RecoveryMandate` while they still control their +key, designating the notary set and threshold. + +| Field | Type | Required | Description | +|---|---|---|---| +| `principal_did` | String | REQUIRED | DID of the principal creating the mandate | +| `threshold` | Integer | REQUIRED | M: minimum co-signatures required (1 ≤ M ≤ N) | +| `notary_dids` | Array\ | REQUIRED | N designated notary DIDs (no duplicates) | +| `created_at` | DateTime | REQUIRED | Mandate creation timestamp | +| `signature` | String | REQUIRED | Ed25519 signature by the principal | + +Constraints: +- `threshold` MUST be ≥ 1 and ≤ `notary_dids.length`. +- `notary_dids` MUST NOT contain duplicate entries. +- The mandate MUST be signed by the principal's current key. +- Only one recovery mandate per principal DID. A new mandate + replaces any previous one. + +#### 13.5.2. Recovery Request + +When recovery is needed, a `RecoveryRequest` is created identifying +the old principal, the new principal keypair, and the authorizing +recovery mandate. + +| Field | Type | Required | Description | +|---|---|---|---| +| `old_principal_did` | String | REQUIRED | DID of the principal being recovered | +| `new_principal_did` | String | REQUIRED | DID of the new principal keypair | +| `recovery_mandate_hash` | String | REQUIRED | SHA-256 hash of the authorizing RecoveryMandate | +| `requested_at` | DateTime | REQUIRED | Request timestamp | + +The canonical bytes of the recovery request are the message that each +notary signs independently. + +#### 13.5.3. Partial Recovery Signature (Blind) + +Each notary signs the recovery request independently. Notaries MUST +NOT communicate with each other during recovery — they learn nothing +about which other notaries have been contacted (threshold blind +signature scheme). + +Before signing, a notary MUST verify: +1. The recovery mandate was signed by the old principal. +2. The notary's own DID is in the designated notary set. +3. The request references the correct recovery mandate hash. +4. The request's `old_principal_did` matches the mandate. + +| Field | Type | Required | Description | +|---|---|---|---| +| `notary_did` | String | REQUIRED | DID of the signing notary | +| `signature` | String | REQUIRED | Ed25519 signature over the RecoveryRequest canonical bytes | +| `signed_at` | DateTime | REQUIRED | Timestamp of the notary's signature | + +#### 13.5.4. Recovery Proof Assembly + +A recovery coordinator collects M partial signatures and assembles a +`RecoveryProof`. Verification of the proof MUST check: + +1. The recovery mandate was signed by the old principal. +2. At least M partial signatures are present. +3. All signers are in the designated notary set. +4. No duplicate signers. +5. All partial signatures are cryptographically valid. + +#### 13.5.5. Revocation Proof and Broadcast + +After successful recovery, a `RevocationProof` is created and +broadcast to federation peers. + +| Field | Type | Required | Description | +|---|---|---|---| +| `old_principal_did` | String | REQUIRED | The revoked DID | +| `new_principal_did` | String | REQUIRED | The replacement DID | +| `recovery_proof_hash` | String | REQUIRED | SHA-256 hash of the RecoveryProof | +| `revoked_at` | DateTime | REQUIRED | Revocation timestamp | +| `signature` | String | REQUIRED | Ed25519 signature by the new principal key | + +The revocation proof MUST be signed by the new principal key (proving +possession). Federation peers that receive a valid revocation MUST: +- Mark the old principal DID as revoked. +- Reject any future operations using the old DID. +- Remove the old recovery mandate from their NotarySet. + +#### 13.5.6. NotarySet Registry + +Each federation node maintains a `NotarySet` — a registry of recovery +mandates queryable by principal DID. The NotarySet: +- Stores signed recovery mandates. +- Tracks revoked principal DIDs. +- Rejects mandate registration for already-revoked DIDs. +- Processes revocation broadcasts from federation peers. + +#### 13.5.7. Security Properties + +- **No central authority.** Recovery requires M independent notaries. +- **Blind co-signing.** Notaries do not learn which other notaries + participate in a recovery event. +- **Old key revocation.** The old principal DID is cryptographically + revoked and broadcast to all federation peers. +- **Notary set immutability.** The notary set is fixed at mandate + creation time by the principal. It cannot be modified without + creating a new mandate signed by the principal. +- **Threshold enforcement.** Fewer than M signatures MUST be rejected. + Duplicate signers MUST be rejected. + +### 13.6. TEE Attestation + +A mandate or session MAY carry a Trusted Execution Environment +(TEE) attestation to provide evidence that an agent is executing +within an isolated enclave. TEE attestation is OPTIONAL and does +NOT elevate a TEE to equivalence with local trust (Section 3.4). + +#### 13.6.1. Attestation Object + +| Field | Type | Required | Description | +|---|---|---|---| +| `enclave_type` | String | REQUIRED | TEE platform identifier (e.g., `"sgx"`, `"sev-snp"`, `"trustzone"`) | +| `measurement` | String | REQUIRED | Enclave measurement hash (base64url-no-pad) | +| `attestation_report` | String | REQUIRED | Platform-specific attestation report (base64url-no-pad) | +| `timestamp` | DateTime | REQUIRED | Attestation generation timestamp (RFC 3339) | +| `nonce` | String | REQUIRED | Challenge nonce binding this attestation to the current session (UUID v4) | + +#### 13.6.2. Attestation Verification + +A verifier MUST: + +1. Verify the `attestation_report` against the TEE platform's + root of trust (platform-specific, out of scope). +2. Verify that `measurement` matches an expected enclave binary + hash (implementation-defined allowlist). +3. Verify that `nonce` matches the session's challenge nonce. +4. Verify that `timestamp` is within an acceptable window + (implementations SHOULD reject attestations older than 60 + seconds). + +#### 13.6.3. Trust Boundaries + +TEE attestation provides evidence of code integrity, not +behavioral correctness. Specifically: + +- A TEE attestation MUST NOT be treated as equivalent to a + mandate. An agent in a TEE still requires a valid mandate chain. +- A TEE attestation MUST NOT be used to expand scope beyond what + the mandate permits. +- The principal MAY use TEE attestation as an input to + auto-approval policies (Section 13.4) but MUST NOT be required + to accept TEE attestation as a substitute for consent. + +#### 13.6.4. Implementation Notes + +The reference implementation provides TEE attestation support via +the `pap-tee` crate, which is compiled only when opted into as a +dependency. Integration with `pap-core` is gated behind the `tee` +Cargo feature flag. + +- **`pap-tee` crate**: Defines `AttestationEvidence`, + `EnclaveType`, the `AttestationVerifier` trait, and a + `SoftwareSimulator` for integration testing without hardware. +- **`pap-core` `tee` feature**: Adds an optional `attestation` + field to `Session` and provides `open_with_attestation()`. +- **`ProtocolMessage::TokenAccepted`**: Carries an optional + `attestation` field as opaque JSON (`serde_json::Value`). + Receivers parse it via `AttestationEvidence::from_value()`. + +The `SoftwareSimulator` uses `EnclaveType::Software` and signs +attestation reports with an Ed25519 key. It is intended for +conformance testing (Appendix D, tests E-13 through E-15) and +MUST NOT be deployed in production. + +### 13.7. Payment Proof Validation + +Section 13.1 defines the payment proof integration point. This +section specifies the validation requirements that a conformant +implementation MUST satisfy when payment proofs are present. + +#### 13.7.1. Proof Format Registry + +PAP defines the following payment proof format prefixes: + +| Prefix | Protocol | Description | +|---|---|---| +| `ecash:blind:v1:` | Chaumian ecash | Blind-signed mint tokens (Section 13.1) | +| `ln:preimage:v1:` | Lightning Network | Hash preimage proof of payment | +| `zk:receipt:v1:` | Zero-knowledge proof | ZK proof of value transfer | + +Implementations MAY support additional formats using the +`pap:payment:` namespace prefix. + +#### 13.7.2. Validation Requirements + +A receiving agent that requires payment MUST: + +1. Parse the `payment_proof` field and identify the format prefix. +2. If the format is not supported, reject the mandate with a + `PaymentFormatUnsupported` error. +3. Verify the proof against the appropriate payment backend + (mint, Lightning node, or ZK verifier). The verification + protocol is out of scope for this specification. +4. Verify that the proof amount meets the agent's minimum + requirement for the requested action. +5. Verify that the proof has not been previously consumed + (double-spend protection). + +#### 13.7.3. Privacy Requirements + +- Payment proof verification MUST NOT reveal the payer's + identity to the payment backend. +- The receiving agent MUST NOT store payment proofs beyond the + session duration unless required by applicable law. +- Payment proofs MUST NOT appear in transaction receipts + (Section 11.5). + +### 13.8. Chat and Real-Time Communication + +#### 13.8.1. Overview + +PAP provides a natural foundation for zero-trust, privacy-preserving +real-time communication between principals. A personal agent MAY +advertise `schema:CommunicateAction` in the federation registry — exactly +as a service agent advertises `schema:SearchAction`. This makes a +principal discoverable for chat without requiring a phone number, +email address, or centrally-administered identity. Discoverability is +opt-in, scoped, and revocable through the standard mandate system. + +Chat is not a new protocol. It is the **Phase 4 streaming extension** of +the standard 6-phase handshake, applied to a `schema:CommunicateAction` +session. + +#### 13.8.2. Capability Grant + +A `CapabilityToken` scoped to `schema:CommunicateAction` MUST be issued +by the initiating principal (or a delegated orchestrator) and signed with +a principal key. The token: + +- MUST set `action = "schema:CommunicateAction"`. +- MUST set `target_did` to the receiving principal's agent DID. +- MAY set a `ttl` appropriate for the conversation duration. +- MAY carry a `scope` restricting the permitted communication modes + (e.g., `text-only`, `text+audio`, `text+audio+video`). + +#### 13.8.3. Phase 4 Streaming Mode + +After Phase 3 (disclosure), instead of a single task execution, +the session transitions to **streaming mode**: + +1. **Phase 4 execute** (client → server, no payload): the receiving + agent returns `ExecutionResult` containing a `schema:Conversation` + JSON-LD object. This signals that the session SHOULD remain open. + +2. **StreamingMessage frames** (bidirectional, Phase 4): either party + MAY send `StreamingMessage` frames carrying DIDComm `basicmessage` + protocol payloads (see Section 13.8.5). Each frame MUST include: + - `id`: a UUID for ack correlation. + - `content`: a JSON object conforming to the DIDComm `basicmessage` + body schema. + +3. **StreamingAck** (responding side): upon receiving a `StreamingMessage`, + the server MUST reply with either a `StreamingAck` (delivery confirmed) + or a `StreamingMessage` (reply). + +4. The session MUST remain open until either party sends `SessionClose` + (Phase 6). Implementations SHOULD NOT proceed to Phase 5 (receipt + co-signing) until the conversation is concluded. + +#### 13.8.4. Message Format (DIDComm basicmessage) + +The `content` field of each `StreamingMessage` MUST conform to the +DIDComm `basicmessage` 2.0 protocol body: + +```json +{ + "type": "https://didcomm.org/basicmessage/2.0/message", + "id": "", + "body": { + "content": "" + } +} +``` + +The DIDComm wrapping (plaintext, signed, or encrypted) is applied at the +`Envelope` layer via `PapToDIDComm` (Section 5.6). For chat sessions, +implementations SHOULD use at minimum `DIDCommSigned` to bind each +message to the sender's session DID. + +#### 13.8.5. Receipt + +Upon `SessionClose`, the receipt (Phase 5) MUST record: + +- `action = "schema:CommunicateAction"` +- `executed`: a summary string, e.g., `"schema:Conversation"`. +- `disclosed_by_initiator` / `disclosed_by_receiver`: property + references only (e.g., `["schema:name"]`). Message **content** + MUST NOT appear in receipts. +- Both parties' session DIDs as `initiating_agent_did` / + `receiving_agent_did` (ephemeral, unlinked from principal DIDs). + +#### 13.8.6. Group Chat Rooms + +A group chat room is an agent with its own DID that implements +`AgentHandler` and maintains one session per member: + +- The room DID is registered in the federation with + `capability: ["schema:CommunicateAction"]`. +- The room owner issues a separate `CapabilityToken` to each + member, all targeting the room DID. +- Each member runs the standard 6-phase handshake against the + room DID. After Phase 4 (streaming mode open), the room agent + fans out each `StreamingMessage` to all other connected members. +- Group membership is enforced by the token system: only principals + holding a valid token may connect. Revocation follows the standard + mandate revocation flow (Section 8). +- Rooms MAY be hosted locally (Papillon instance) or on any + federation peer. A room hosted on a federation peer is + discoverable via its DID advertisement. + +#### 13.8.7. Audio and Video + +Audio and video calls follow the same pattern as text chat, using +WebRTC as the media transport: + +1. PAP Phases 1–4 establish identity, authorization, and streaming + mode. The `CapabilityToken` scope SHOULD include the permitted + media types (e.g., `text+audio+video`). +2. **SDP negotiation** is carried via `StreamingMessage` frames: + the offerer sends a `StreamingMessage` whose `content.body` + contains the SDP offer; the answerer replies with SDP answer. + ICE candidates are exchanged as subsequent frames. +3. WebRTC DTLS-SRTP establishes the media channel out-of-band. + PAP does not inspect or relay media. +4. Implementations MAY route ICE/TURN through an OHTTP relay to + conceal participant IP addresses. +5. The PAP receipt records call metadata (duration, participant + session DIDs, permitted media scope) but MUST NOT include + audio or video content. + +#### 13.8.8. Privacy Properties + +Chat sessions inherit all PAP privacy guarantees: + +- **Ephemeral session DIDs** — neither party's principal DID + appears in message frames or SDP. +- **OHTTP relay** — IP addresses hidden from the relay operator. +- **Receipts** — property references only; no message content. +- **Discoverability** — controlled by the principal's federation + advertisement; opt-in. +- **Forward secrecy** — DIDComm anoncrypt (`ECDH-ES + A256GCM`) + MAY be applied to `StreamingMessage` content for per-message + forward secrecy. + +--- + +## 14. Transport Binding + +### 14.1. HTTP/JSON Transport + +PAP defines an HTTP/JSON transport binding for the 6-phase +handshake. This binding is the default transport for PAP v1.0. +Implementations MAY define additional transport bindings. + +### 14.2. Agent Server Endpoints + +A receiving agent MUST expose the following HTTP endpoints: + +| Method | Path | Phase | Request | Response | +|---|---|---|---|---| +| POST | `/session` | 1 | `TokenPresentation` | `TokenAccepted` or `TokenRejected` | +| POST | `/session/{id}/did` | 2 | `SessionDidExchange` | `SessionDidAck` | +| POST | `/session/{id}/disclosure` | 3 | `DisclosureOffer` | `DisclosureAccepted` | +| POST | `/session/{id}/execute` | 4 | (empty body) | `ExecutionResult` | +| POST | `/session/{id}/receipt` | 5 | `ReceiptForCoSign` | `ReceiptCoSigned` | +| POST | `/session/{id}/close` | 6 | `SessionClose` | `SessionClosed` | + +The `{id}` path parameter is the session ID returned in Phase 1. + +### 14.3. Agent Handler Interface + +Implementations MUST implement a handler interface with the +following operations: + +| Operation | Phase | Input | Output | +|---|---|---|---| +| `handle_token` | 1 | CapabilityToken | (session_id, receiver_session_did) | +| `handle_did_exchange` | 2 | session_id, initiator_session_did | () | +| `handle_disclosure` | 3 | session_id, disclosures | () | +| `execute` | 4 | session_id | JSON result | +| `co_sign_receipt` | 5 | TransactionReceipt | TransactionReceipt (co-signed) | +| `handle_close` | 6 | session_id | () | + +### 14.4. Endpoint Resolution + +Endpoint resolution maps a DID to a transport endpoint URL. In +production, this SHOULD be backed by DID Document `service` +endpoints. Implementations MAY use in-memory registries for +development and testing. + +### 14.5. Content Type + +All HTTP request and response bodies MUST use `Content-Type: +application/json`. Implementations SHOULD set `Accept: +application/json` on requests. + +### 14.6. Error Handling + +If a phase handler returns an error, the server MUST respond with +HTTP status 500 and a `ProtocolMessage::Error` payload containing +a `code` and `message`. + +If the request body does not match the expected message type for +the endpoint, the server MUST respond with HTTP status 400. + +### 14.7. WebSocket Transport + +Implementations MAY support a WebSocket transport binding as an +alternative to the HTTP/JSON binding. The WebSocket binding is +OPTIONAL and provides full-duplex communication for sessions that +benefit from lower-latency message exchange. + +#### 14.7.1. Connection Lifecycle + +1. The initiating agent opens a WebSocket connection to the + receiving agent's WebSocket endpoint. +2. All 6 phases of the session handshake (Section 6.3) are + conducted as JSON messages over the WebSocket connection. +3. Each message MUST be a JSON-serialized `Envelope` (Section 8.2). +4. The connection MUST be closed after Phase 6 (session close). + +#### 14.7.2. Endpoint Format + +A WebSocket endpoint MUST use the `wss://` scheme. Implementations +MUST NOT use unencrypted `ws://` connections in production. + +The endpoint URL MUST be published in the agent's DID Document +`service` array with `type` set to `"PAPWebSocket"`: + +```json +{ + "id": "did:key:z...#pap-ws", + "type": "PAPWebSocket", + "serviceEndpoint": "wss://agent.example.com/pap/ws" +} +``` + +#### 14.7.3. Message Framing + +Each WebSocket text frame MUST contain exactly one JSON-serialized +`Envelope`. Binary frames MUST NOT be used. Implementations MUST +reject connections that send binary frames. + +#### 14.7.4. Sequence Enforcement + +Envelope sequence number rules (Section 8.2.2) apply identically +over WebSocket. Out-of-order messages MUST be rejected. + +### 14.8. Oblivious HTTP (OHTTP) Transport + +Implementations MAY support Oblivious HTTP [RFC 9458] as a +transport binding. OHTTP provides request unlinkability at the +network layer, preventing the receiving agent's operator from +correlating requests by IP address. + +#### 14.8.1. Architecture + +An OHTTP deployment interposes a relay between the initiating +agent and the receiving agent: + +``` +Initiator -> OHTTP Relay -> Receiving Agent (Gateway) +``` + +The relay sees the initiator's IP but not the request content. +The receiving agent sees the request content but not the +initiator's IP. + +#### 14.8.2. Encapsulation + +Each PAP protocol message MUST be encapsulated as an OHTTP +Binary HTTP request targeting the corresponding HTTP/JSON +endpoint (Section 14.2). The `Content-Type` MUST remain +`application/json`. + +#### 14.8.3. Key Configuration + +The receiving agent MUST publish its OHTTP key configuration +in its DID Document `service` array with `type` set to +`"PAPObliviousHTTP"`: + +```json +{ + "id": "did:key:z...#pap-ohttp", + "type": "PAPObliviousHTTP", + "serviceEndpoint": "https://agent.example.com/pap/ohttp", + "ohttpKeyConfig": "" +} +``` + +#### 14.8.4. Relay Selection + +The initiating agent selects the OHTTP relay. The relay MUST +NOT be operated by the same entity as the receiving agent. The +protocol does not define relay discovery; implementations +SHOULD allow the principal to configure trusted relays. + +### 14.9. DIDComm Transport + +Implementations MAY support DIDComm Messaging v2 [DIDCOMM-V2] +as a transport binding. DIDComm provides authenticated encryption +at the message layer, enabling transport-independent secure +messaging between agents identified by DIDs. + +#### 14.9.1. Message Mapping + +Each PAP protocol message (Section 8.1) MUST be wrapped in a +DIDComm plaintext message with the following mapping: + +| DIDComm Field | Value | +|---|---| +| `type` | `https://pap.dev/protocol/1.0/{message_type}` | +| `from` | Sender's DID (session DID after Phase 2) | +| `to` | Array containing recipient's DID | +| `body` | The PAP protocol message payload | +| `created_time` | Envelope timestamp (Unix epoch seconds) | + +Where `{message_type}` is the lowercase, hyphenated form of the +PAP message type (e.g., `token-presentation`, `session-did-exchange`). + +#### 14.9.2. Encryption + +DIDComm messages MUST use authenticated encryption (authcrypt) +after Phase 2 when both session DIDs are known. Phase 1 messages +MAY use anonymous encryption (anoncrypt) since the initiator's +session DID is not yet established. + +#### 14.9.3. Service Endpoint + +A DIDComm-capable agent MUST publish a DIDComm service endpoint +in its DID Document: + +```json +{ + "id": "did:key:z...#pap-didcomm", + "type": "DIDCommMessaging", + "serviceEndpoint": { + "uri": "https://agent.example.com/pap/didcomm", + "accept": ["didcomm/v2"] + } +} +``` + +### 14.10. Transport Negotiation + +When an agent supports multiple transport bindings, the initiating +agent MUST select a transport by inspecting the receiving agent's +DID Document `service` array. The preference order SHOULD be: + +1. OHTTP (strongest privacy properties) +2. DIDComm (authenticated encryption at message layer) +3. WebSocket (lower latency for interactive sessions) +4. HTTP/JSON (default, widest compatibility) + +If the receiving agent's DID Document contains no `service` +entries, the initiating agent MUST fall back to HTTP/JSON with +endpoint resolution (Section 14.4). + +### 14.11. DIDComm v2 Envelope Compatibility + +PAP defines an optional DIDComm v2 envelope compatibility layer +that wraps PAP protocol envelopes inside DIDComm v2 message +formats. This allows PAP agents to interoperate with +DIDComm-native agents without changing the PAP protocol itself. +This section specifies the detailed wire formats used by the +DIDComm transport binding (Section 14.9). + +#### 14.11.1. Design Principles + +- PAP mandate, session, and receipt semantics are fully preserved. +- Only the outer transport envelope changes; the inner PAP + `Envelope` (including its Ed25519 signature) travels intact + inside the DIDComm message body. +- The DIDComm layer provides additional transport-level integrity + (JWS) or confidentiality (JWE) on top of PAP's own signatures. +- This is a shim — existing `pap-transport` behavior is unaffected. + +#### 14.11.2. Plaintext Messages + +A PAP envelope is wrapped in a DIDComm v2 plaintext message: + +```json +{ + "id": "", + "typ": "application/didcomm-plain+json", + "type": "https://pap.baur.dev/proto/1.0/", + "from": "", + "to": [""], + "created_time": , + "body": { } +} +``` + +The `type` field uses PAP message type URIs under the namespace +`https://pap.baur.dev/proto/1.0/`, with kebab-case slugs derived +from the `ProtocolMessage` variant name (e.g., `session-did-ack`, +`execution-result`, `token-presentation`). + +The `body` field contains the complete PAP `Envelope` including +its `signature` field, so the receiving agent can verify the +PAP-level signature independently of the DIDComm layer. + +#### 14.11.3. Signed Messages (Ed25519 JWS) + +A signed DIDComm v2 message uses JWS General JSON Serialization +(RFC 7515) with the `EdDSA` algorithm (RFC 8037): + +```json +{ + "payload": "", + "signatures": [{ + "protected": "", + "signature": "" + }] +} +``` + +The signing input is `ASCII(protected) || '.' || ASCII(payload)` +where both values are base64url-encoded without padding (RFC 4648 +Section 5). The signature is computed with Ed25519 (RFC 8032). + +Verifiers MUST reject messages where: +- The `alg` header value is not `"EdDSA"`. +- The signature does not verify against the expected key. +- The decoded payload is not valid DIDComm v2 plaintext JSON. + +#### 14.11.4. Encrypted Messages (ECDH-ES + A256GCM JWE) + +An encrypted DIDComm v2 message uses JWE JSON Serialization with +anonymous encryption (anoncrypt): + +- **Key Agreement**: `ECDH-ES` (direct, no key wrapping) via + X25519 Diffie-Hellman. The sender generates an ephemeral X25519 + keypair. The recipient's Ed25519 public key is converted to + X25519 using the Edwards-to-Montgomery birational map. +- **Key Derivation**: Concat KDF (NIST SP 800-56A Section 5.8.1) + with `algId = "A256GCM"`, empty `apu`, and + `apv = SHA-256(recipient-did)`. +- **Content Encryption**: AES-256-GCM with a random 96-bit IV. + The base64url-encoded protected header serves as Additional + Authenticated Data (AAD). + +```json +{ + "protected": "", + "recipients": [{ + "header": { "kid": "" }, + "encrypted_key": "" + }], + "iv": "", + "ciphertext": "", + "tag": "" +} +``` + +The protected header contains: + +| Field | Value | +|---|---| +| `typ` | `"application/didcomm-encrypted+json"` | +| `alg` | `"ECDH-ES"` | +| `enc` | `"A256GCM"` | +| `epk` | `{"kty":"OKP","crv":"X25519","x":""}` | +| `apv` | `""` | + +The `encrypted_key` field is empty for ECDH-ES direct key +agreement (the content encryption key is derived directly from +the shared secret). + +#### 14.11.5. Ed25519 to X25519 Key Conversion + +DIDComm v2 encryption requires X25519 keys for key agreement. +PAP agents use Ed25519 keys (via `did:key`). The conversion is: + +- **Public key**: Decompress the Ed25519 compressed Edwards Y + coordinate, then apply the Edwards-to-Montgomery birational map + to obtain the X25519 public key (32 bytes). +- **Private key**: Compute `SHA-512(Ed25519-seed)[0..32]`. The + X25519 library applies standard clamping (clear bits 0-2, + clear bit 255, set bit 254). + +This conversion is consistent: the X25519 public key derived from +the converted private key matches the X25519 public key derived +from the original Ed25519 public key. + +#### 14.11.6. Translation Rules + +| Direction | Operation | +|---|---| +| PAP → DIDComm Plaintext | Serialize PAP `Envelope` into DIDComm `body` | +| PAP → DIDComm Signed | Build plaintext, then apply Ed25519 JWS | +| PAP → DIDComm Encrypted | Build plaintext, then apply ECDH-ES + A256GCM JWE | +| DIDComm Plaintext → PAP | Deserialize `body` field as PAP `Envelope` | +| DIDComm Signed → PAP | Verify JWS, then extract PAP `Envelope` from body | +| DIDComm Encrypted → PAP | Decrypt JWE, then extract PAP `Envelope` from body | + +In all cases, the PAP `Envelope.signature` field (if present) +remains intact and can be verified independently using the +session's ephemeral key. + +--- + +## 15. PAP URI Scheme + +### 15.1. Overview + +The `pap` URI scheme identifies agents, capabilities, and resources within +the Principal Agent Protocol. A `pap://` URI is always an expression of +**intent** — resolving one initiates a PAP mandate-scoped interaction, not +a raw network request. + +The scheme family consists of three variants: + +| Scheme | Meaning | +|---|---| +| `pap://` | PAP-native transport; client negotiates protocol | +| `pap+https://` | PAP mandate scope applied over HTTPS transport | +| `pap+wss://` | PAP mandate scope applied over WebSocket transport | + +`pap+https://` and `pap+wss://` are **recapture schemes**. They apply PAP +semantics — mandate enforcement, selective disclosure, co-signed receipts — +to existing transports. The remote endpoint does not need to implement PAP. +The client enforces the protocol locally. A `pap+https://` URI is still an +HTTPS request under the hood; the principal's mandate scope wraps it +regardless of whether the server is PAP-aware. + +### 15.2. Syntax + +```abnf +pap-uri = pap-scheme "://" pap-authority pap-path [ "?" pap-query ] + +pap-scheme = "pap" / "pap+https" / "pap+wss" + +pap-authority = registry-host / did-authority / catalog-name + +registry-host = host [ ":" port ] + ; authority is the hostname only; agent slug appears in path + +did-authority = "did:key:" base58-multicodec-key + ; PAP parsers MUST treat "did:key:" as an atomic authority + ; token. Standard RFC 3986 host parsing (which disallows + ; colons) MUST NOT be applied to did-authority. A PAP URI + ; parser identifies did-authority by the "did:key:" prefix + ; before applying any other rule. + +catalog-name = 1*( ALPHA / DIGIT / "-" / "_" ) + ; MUST NOT be a reserved word (receipt, canvas, settings) + ; resolved against local catalog before dispatch + +pap-path = registry-path / simple-path + +registry-path = "/agents/" agent-slug "/" schema-action-type +simple-path = "/" schema-action-type + ; Schema.org action type, e.g. "SearchAction" + +pap-query = pap-param *( "&" pap-param ) +pap-param = schema-property "=" pap-value + ; values MUST be percent-encoded per RFC 3986 §2.1 + ; "+" MUST NOT be used as a space encoding in pap-query +``` + +Examples: + +``` +; Networked agent via Chrysalis registry +pap://chrysalis.example.com/agents/arxiv/SearchAction?query=quantum%20computing + +; Direct peer-to-peer via DID (no registry) +pap://did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK/SearchAction + +; Local catalog shorthand — resolved before dispatch +pap://arxiv/SearchAction?query=quantum%20computing +pap://wikipedia/ReadAction?name=Rust%20programming + +; Receipt deep-link +pap://receipt/RCP_abc123 + +; Recapture schemes — PAP scope over existing transports +pap+https://api.example.com/agents/bookings/BuyAction?offer=flight-abc +pap+wss://stream.example.com/agents/feed/ListenAction +``` + +### 15.3. Resolution + +A conforming client MUST resolve a `pap://` URI using the following +priority chain, in order: + +0. **Special authority** — if the authority is one of the reserved words + (`receipt`, `canvas`, `settings`), resolve locally without any network + lookup. See §15.7. Do not proceed to subsequent steps. + +1. **`did:key:` authority** — if the authority begins with `did:key:`, + resolve directly via DID Document endpoint discovery (Section 14.4). + No registry lookup. Initiates a PAP handshake with the identified agent. + +2. **Catalog name** — if the authority contains no `.` character and does + not begin with `did:`, the client MUST check its local agent catalog for + an entry whose `name` field matches the authority (case-insensitive). If + found, rewrite the URI to the agent's registered DID and resolve via + step 1. + +3. **Registry hostname** — if the authority contains a `.` character, or + matches `localhost`, or is a valid IPv4 address or IPv6 literal, treat it + as a Chrysalis registry host. Resolve by querying the registry's + `/agents/{slug}/` routes (Section 14.1) using the path-embedded agent + slug, and initiate a PAP handshake with the returned agent endpoint. + The `.` heuristic MUST NOT be applied to `localhost` or IP literals; + they are always treated as registry hosts. + +If resolution fails at all steps, the client MUST render an inline error in +place of the activated link, showing the unresolved URI and a human-readable +explanation. The client MUST NOT navigate away from the current canvas or +dismiss existing content. The client MUST NOT silently fall back to a raw +HTTP request. + +### 15.4. Action Type and Query Parameters + +The action type path segment MUST be a Schema.org action type +(e.g. `SearchAction`, `BuyAction`, `ReadAction`). For registry URIs the +full path is `/agents/{slug}/{ActionType}`; for catalog and DID URIs the +path is `/{ActionType}`. Clients SHOULD use the action type to pre-filter +agents during resolution — if a catalog agent does not advertise the +requested action type in its `capability` array, it MUST NOT be selected. + +Query parameters MUST use Schema.org property names as keys. Values MUST +be percent-encoded per RFC 3986 §2.1; `+` MUST NOT be used as a space +encoding. Clients MAY pass query parameters directly to the agent as the +intent payload. Agents MAY ignore unknown parameters. + +### 15.5. Recapture Semantics (`pap+https://`, `pap+wss://`) + +When a `pap+https://` or `pap+wss://` URI is resolved: + +1. The active mandate scope MUST be checked before the request is made. If + no mandate is in scope, the client MUST NOT proceed. + +2. The request is made over the underlying transport (HTTPS or WSS) with + the standard PAP session headers included where the server accepts them. + +3. The client MUST record what was disclosed and generate a receipt entry + regardless of whether the server participates in the PAP handshake. + +4. The remote endpoint's response is treated as agent output and rendered + via the standard block renderer pipeline. + +For `pap+wss://` URIs, the connection lifecycle (establishment, keepalive, +and termination) follows the mandate-scoped session lifecycle defined in +§5. Streaming-specific semantics (chunked responses, event framing) are +deferred to v1.1. + +This allows principals to bring existing web services under PAP governance +without requiring those services to be modified. + +**v1.0 scope note:** In v1.0, `pap+https://` and `pap+wss://` URIs are +parsed and classified by conforming clients. Full mandate enforcement +(steps 1–4 above) requires the mandate enforcement layer, which is deferred +to a post-v1.0 milestone. v1.0 clients MUST NOT silently downgrade a +`pap+https://` URI to an unscoped HTTPS request. They MUST either enforce +the mandate or reject the request with a clear principal-visible error +explaining that recapture enforcement is not yet available. + +### 15.6. Link Rendering + +Any string value in a JSON-LD agent response that begins with `pap://`, +`pap+https://`, or `pap+wss://` MUST be rendered as a navigable link by +conforming clients. Activating such a link MUST dispatch the URI as intent +through the same pipeline as a principal-typed query — it is not a browser +navigation event. + +This enables agent-rendered content to form a navigable graph of +intent-links without requiring any special page routing. Every link is a +new PAP interaction. + +**Agent-rendered link security:** Clients MUST visually distinguish links +originating from agent-rendered content from links typed directly by the +principal. Before dispatching an agent-rendered `pap://` link, clients +SHOULD display the full URI and the identity of the agent that produced it, +and require explicit principal confirmation. This prevents injection attacks +where a malicious or compromised agent response induces the client to +execute unintended actions. + +Agent-rendered links MUST NOT activate the `settings`, `canvas`, or +`receipt` special authorities (§15.7). Clients MUST silently reject +such links and MAY log the attempt for principal review. + +### 15.7. Special Authorities + +The following authority values are reserved and MUST be handled by the +client without registry or catalog lookup: + +| Authority | Meaning | +|---|---| +| `receipt` | Deep-link to a receipt by session ID. `pap://receipt/{session-id}` opens the receipt detail view. | +| `canvas` | Deep-link to a canvas block. `pap://canvas/{canvas-id}/{block-id}` navigates to the referenced block. | +| `settings` | Opens the settings panel. `pap://settings/{tab}` opens a specific tab. | + +--- + +## 16. Security Considerations + +### 16.1. Cryptographic Algorithms + +PAP v1.0 uses exclusively: + +- **Ed25519** (RFC 8032) for all signatures. +- **SHA-256** (FIPS 180-4) for all hashes. +- **Base64url without padding** (RFC 4648 Section 5) for all + binary-to-text encoding. +- **Base58btc** for DID key encoding. + +Implementations MUST use these algorithms for PAP v1.0. All signable +structures carry a `SignatureAlgorithm` field (serialized as the JWS +`alg` string, e.g. `"EdDSA"`) to enable forward-compatible algorithm +negotiation. The field defaults to Ed25519 when absent. Implementations +MUST reject algorithms they do not support. The `did:key` multicodec +prefix encodes the algorithm of the public key. + +Future versions of this specification MAY introduce additional algorithms +(e.g., ML-DSA-65 for post-quantum resistance). + +### 16.2. Key Management + +- Principal private keys SHOULD be stored in hardware security + modules or platform authenticators (WebAuthn). They MUST NOT be + stored in plaintext in configuration files or environment + variables in production. +- Session private keys MUST be held only in memory for the + duration of the session. They MUST NOT be persisted to disk. +- Signing keys for agent operators (used to sign advertisements) + SHOULD be protected with access controls appropriate to the + deployment environment. + +### 16.3. Nonce Management + +- Capability token nonces MUST be stored in a consumed-nonce set + for at least the duration of the token's validity period. +- Implementations SHOULD periodically purge expired nonces to + prevent unbounded growth of the consumed-nonce set. +- If a receiver restarts and loses its consumed-nonce set, it + SHOULD reject all tokens issued before the restart by comparing + `issued_at` against its restart timestamp. + +### 16.4. Replay Protection + +Multiple layers provide replay protection: + +1. **Token nonces:** Each capability token has a UUID v4 nonce + consumed on first use. +2. **Envelope sequencing:** Sequence numbers are monotonically + increasing within a session. Out-of-order envelopes MUST be + rejected. +3. **Token expiry:** Tokens carry an `expires_at` timestamp. + Expired tokens MUST be rejected. +4. **Session ephemerality:** Session keys are discarded at close. + A replayed session message cannot be verified against the + original session keys. + +### 16.5. Denial of Service + +- Implementations SHOULD rate-limit token presentation requests + to prevent resource exhaustion from session initiation floods. +- Federation sync operations SHOULD be rate-limited per peer. +- Marketplace registries SHOULD limit the number of advertisements + per operator DID. + +### 16.6. Man-in-the-Middle + +- After Phase 2 (DID exchange), all envelopes MUST be signed by + the sender's session key. An attacker who intercepts envelopes + cannot forge valid signatures without the session private key. +- The initial token presentation (Phase 1) is protected by the + orchestrator's signature on the capability token. An attacker + cannot forge a valid token without the orchestrator's private + key. +- Implementations SHOULD use TLS for all HTTP transport to protect + against passive eavesdropping. + +### 16.7. Context Leakage + +- The `DisclosureOffer` (Phase 3) MUST contain only SD-JWT + disclosures permitted by the mandate's disclosure set. +- The orchestrator MUST verify that the agent's + `requires_disclosure` is satisfiable by the mandate before + issuing a capability token. An agent MUST NOT receive a token + if its disclosure requirements exceed the principal's + authorization. +- Receipts MUST NOT contain personal data values (Section 11.5). + +### 16.8. Mandate Chain Depth + +Implementations SHOULD enforce a maximum mandate chain depth to +prevent resource exhaustion during chain verification. A maximum +depth of 10 is RECOMMENDED. + +### 16.9. Clock Skew + +- Implementations MUST use UTC for all timestamps. +- Implementations SHOULD tolerate clock skew of up to 30 seconds + for token expiry and mandate TTL checks. +- Implementations MAY use NTP or similar time synchronization + protocols to minimize skew. + +### 16.10. Canonical JSON Determinism + +The security of mandate hashing and signature verification depends +on deterministic JSON serialization. Implementations MUST ensure +that the canonical JSON form produces identical bytes for the same +logical content. + +Implementations SHOULD: +- Use a JSON serializer that produces consistent key ordering. +- Represent numbers without unnecessary precision. +- Use RFC 3339 with explicit UTC offset for all timestamps. + +If an implementation cannot guarantee deterministic JSON output, +it MUST use an alternative canonical form (e.g., JCS [RFC 8785]) +and document the choice. + +### 16.11.

Introduction + +1.1. Problem Statement + + Existing agent-to-agent protocols authenticate agents as platform + entities, not as delegates of human principals. None enforce context + minimization at the protocol level. Disclosure is implementation- + dependent. Session ephemerality is undefined. Execution isolation + is absent--agents run in the same address space as the orchestrator + or other services, creating blast radius problems even when + disclosure is minimized. Economic models underneath these protocols + are compatible with platform capture through cloud compute metering. + +1.2. Design Goals + + PAP is designed to satisfy the following goals: + + 1. The human principal is the root of trust for every transaction. + + + + +Baur Expires 21 November 2026 [Page 6] + +Internet-Draft PAP May 2026 + + + 2. Context disclosure is enforced by the protocol at the request + boundary (via SD-JWT). + 3. Execution is isolated at the process boundary via OS-level + capabilities. + 4. Sessions are ephemeral by design; no persistent correlation. + 5. Delegation is hierarchical with cryptographically enforced + bounds. + 6. Co-signed receipts prove both disclosure scope and execution + constraints. + 7. No novel cryptography, no token economy, no central registry. + 8. Any compliant implementation MUST be buildable from this document + alone, without reference to a specific programming language. + +1.3. Protocol Overview + + A PAP transaction involves: + + * A *human principal* who holds a device-bound keypair. + * An *orchestrator agent* operating under a root mandate. + * One or more *downstream agents* operating under delegated + mandates, each executing in sandboxed isolation. + * A *marketplace* for agent discovery and disclosure filtering. + * A *6-phase session handshake* between pairs of agents. + * *Request boundary security* via SD-JWT selective disclosure + (minimize what the agent sees). + * *Execution boundary security* via OS sandboxing (minimize what the + agent can do). + * *Co-signed receipts* recording property references and enforcement + proof, never values. + +2. Conventions and Terminology + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and + "OPTIONAL" in this document are to be interpreted as described in BCP + 14 [RFC 2119] [RFC 8174] when, and only when, they appear in all + capitals, as shown here. + +2.1.

PAP URI Scheme + +15.1. Overview + + The pap URI scheme identifies agents, capabilities, and resources + within the Principal Agent Protocol.

They apply PAP + semantics -- mandate enforcement, selective disclosure, co-signed + receipts -- to existing transports. The remote endpoint does not + need to implement PAP. The client enforces the protocol locally. A + pap+https:// URI is still an HTTPS request under the hood; the + principal's mandate scope wraps it regardless of whether the server + is PAP-aware. + +15.2.

See Section 15.7. Do not proceed to subsequent + steps. + + 2. *did:key: authority* -- if the authority begins with did:key:, + resolve directly via DID Document endpoint discovery + (Section 14.4). No registry lookup. Initiates a PAP handshake + with the identified agent. + + 3. *Catalog name* -- if the authority contains no . character and + does not begin with did:, the client MUST check its local agent + catalog for an entry whose name field matches the authority + (case-insensitive). If found, rewrite the URI to the agent's + registered DID and resolve via step 1. + + 4. *Registry hostname* -- if the authority contains a . character, + or matches localhost, or is a valid IPv4 address or IPv6 literal, + treat it as a Chrysalis registry host. Resolve by querying the + registry's /agents/{slug}/ routes (Section 14.1) using the path- + embedded agent slug, and initiate a PAP handshake with the + returned agent endpoint. The . heuristic MUST NOT be applied to + localhost or IP literals; they are always treated as registry + hosts. + + + + + +Baur Expires 21 November 2026 [Page 70] + +Internet-Draft PAP May 2026 + + + If resolution fails at all steps, the client MUST render an inline + error in place of the activated link, showing the unresolved URI and + a human-readable explanation.

Action Type and Query Parameters + + The action type path segment MUST be a Schema.org action type (e.g. + SearchAction, BuyAction, ReadAction). For registry URIs the full + path is /agents/{slug}/{ActionType}; for catalog and DID URIs the + path is /{ActionType}. Clients SHOULD use the action type to pre- + filter agents during resolution -- if a catalog agent does not + advertise the requested action type in its capability array, it MUST + NOT be selected. + + Query parameters MUST use Schema.org property names as keys. Values + MUST be percent-encoded per RFC 3986 Section 2.1; + MUST NOT be used + as a space encoding. Clients MAY pass query parameters directly to + the agent as the intent payload. Agents MAY ignore unknown + parameters. + +15.5. Recapture Semantics (pap+https://, pap+wss://) + + When a pap+https:// or pap+wss:// URI is resolved: + + 1. The active mandate scope MUST be checked before the request is + made. If no mandate is in scope, the client MUST NOT proceed. + + 2.

The client MUST record what was disclosed and generate a receipt + entry regardless of whether the server participates in the PAP + handshake. + + 4. The remote endpoint's response is treated as agent output and + rendered via the standard block renderer pipeline. + + For pap+wss:// URIs, the connection lifecycle (establishment, + keepalive, and termination) follows the mandate-scoped session + lifecycle defined in Section 5. Streaming-specific semantics + (chunked responses, event framing) are deferred to v1.1. + + This allows principals to bring existing web services under PAP + governance without requiring those services to be modified. + + + + +Baur Expires 21 November 2026 [Page 71] + +Internet-Draft PAP May 2026 + + + *v1.0 scope note:* In v1.0, pap+https:// and pap+wss:// URIs are + parsed and classified by conforming clients.

Link Rendering + + Any string value in a JSON-LD agent response that begins with pap://, + pap+https://, or pap+wss:// MUST be rendered as a navigable link by + conforming clients. Activating such a link MUST dispatch the URI as + intent through the same pipeline as a principal-typed query -- it is + not a browser navigation event. + + This enables agent-rendered content to form a navigable graph of + intent-links without requiring any special page routing. Every link + is a new PAP interaction. + + *Agent-rendered link security:* Clients MUST visually distinguish + links originating from agent-rendered content from links typed + directly by the principal. Before dispatching an agent-rendered + pap:// link, clients SHOULD display the full URI and the identity of + the agent that produced it, and require explicit principal + confirmation. This prevents injection attacks where a malicious or + compromised agent response induces the client to execute unintended + actions. + + Agent-rendered links MUST NOT activate the settings, canvas, or + receipt special authorities (Section 15.7).

Purpose + +A single-page, self-contained assessment tool that evaluates an organization's infrastructure and security posture for deploying the Principal Agent Protocol (PAP). It produces a dual output: + +1. A **plaintext summary** embedded in a `mailto:` body for immediate submission to Baur Software. +2.

Architecture + +### 2.1 Page Structure + +- **One HTML file:** `docs/assess.html` +- **Design system:** Uses the same CSS tokens as the existing docs site (Satoshi, DM Sans, JetBrains Mono, purple `#6c5ce7`, wing spectrum colors). CSS is **inlined** so the report requires no external stylesheet. +- **No framework:** Vanilla JavaScript only. No Webpack, Vite, Leptos, or Yew. The existing docs site is static HTML and this file must follow that pattern. + +### 2.2 Two Views in One Page + +| View | Description | Persistence | +|------|-------------|-------------| +| **Wizard** | Multi-step questionnaire. One section visible at a time. | `sessionStorage` saves answers after every section change. | +| **Report** | Self-contained HTML string generated client-side. Rendered via `document.open()` / `document.write()` into the **same tab**. | Not persisted; re-generated from `sessionStorage` on demand. | + +### 2.3 State Management + +- All answers stored in `sessionStorage` under key `pap_assessment_state`. +- State is a JSON object: `{ role, answers: { sectionId: { questionId: value } }, contact }`. +- On page load: if `sessionStorage` has state, offer "Resume assessment" or "Start over". +- On report generation: state is read but **not** cleared. The "Back to Assessment" button restores the wizard DOM from the saved state. + +### 2.4 Report Generation + +The report HTML string is assembled in-memory with all CSS inlined via a `
