Coordination note from sprint planning: PX means Persona eXperience, the Continuum-side persona-facing surface over AIRC traffic. It is not an AIRC dependency and not currently a separate package name to chase. Keep the dependency direction clean: AIRC is lightweight generic transport/collaboration substrate (messages, transcript, queue, file/pointer delivery, timestamps, identities). Continuum/PX consumes AIRC and owns persona semantics: PersonaInbox, CognitionTrace, admission gates, Engram/base-entity persistence, recall, UI/brain projections, and project rules. Any types added here should be Rust serde/ts-rs friendly and should not require AIRC to know about Continuum, forge-alloy, or persona cognition.

Concrete code pointers for the first implementation slice:

• src/workers/continuum-core/src/persona/types.rs has InboxMessage, SenderType, QueueItem, and ts-rs export conventions.
• src/workers/continuum-core/src/persona/inbox.rs has PersonaInboxFrame and frame-drain metrics.
• src/workers/continuum-core/src/persona/trace.rs has CognitionTrace and seam conventions; add admission/relevance/dedup seams here or as constants near the new module.
• src/workers/continuum-core/src/orm/types.rs has generic DataRecord, RecordMetadata, and TS export style if Engram starts as a typed record/projection before a full entity.
• src/workers/continuum-core/src/persona/mod.rs is the export surface for new Rust persona types.
• Generated TS lands under src/shared/generated/persona/* or a new focused namespace if the repo already has one for cognition.

Recommended smallest slice: add Rust serde/ts-rs value types only first: AircEvent, AircEventKind, AircProvenance, PersonaInboxCandidate, Engram, EngramKind, EngramOrigin, AdmissionDecision, AdmissionError. Add a pure conversion/admission function with tests. Keep persistence and live AIRC polling separate unless the local seams are already obvious.

Protocol-compatibility note: Continuum should not care whether a peer used the official AIRC CLI, another client, or hand-rolled compatible AIRC packets. The bridge should admit data by contract: valid envelope/schema, timestamp, provenance, sender identity, signatures/hashes/proof material, trust policy, and replay/dedup checks. Implementation provenance is secondary; verifiable data and proof are the boundary.

Closed after Continuum #1129 merged to canary at f6c25bf. PR-1 delivered Rust-source Engram/AIRC origin/admission/trust membrane types plus ts-rs generated TS exports. Follow-up bridge/admission runtime work should use new queue cards.
