v2.1.0 — Math on the Wire

OSMP encodes instructions. EML encodes mathematics. Both ship in the same package.

This release adds the EML evaluator — a companion math-on-the-wire layer — across Python, Go, and TypeScript, plus two new MCP tools. Purely additive; no breaking changes.

What's new

EML across three languages (sdk/python/osmp/eml.py, sdk/go/osmp/eml/, sdk/typescript/src/eml.ts)

Based on Odrzywołek (2026, arXiv:2603.21852): a single binary operator eml(x, y) = exp(x) − ln(y), together with the constant 1, generates the standard calculator function basis — exp, ln, sin, cos, sqrt, arithmetic, and more — as compact expression trees. A full sin(x) or sqrt(x) approximation fits in fewer than 100 bytes on the wire.

• Zero runtime dependencies. Uses only standard-library math primitives.
• 16 pre-verified base corpus entries and 4 multi-variable arithmetic compounds (neg, +, ×, linear calibration).
• Compact wire encodings for constrained-channel transmission.

Cross-language byte-exact determinism

All three language implementations produce the identical SHA-256 corpus fingerprint:

Every platform, every runtime, every deployment — identical bits out of the same encoded chain.

Dual-mode precision

• Fast mode (fdlibm-derived, 1-ULP accurate) — included publicly under Apache 2.0. Correct for LoRa / BLE / edge-ML, drone swarm coordination, constrained-channel telemetry, and general scientific computation.
• Precision mode (correctly-rounded, audit-grade) — available under commercial license for regulated-industry applications: medical (IEC 62304), aerospace (DO-178C), nuclear (IEC 61513), audit-grade financial, cryptographic protocol-frame hash inputs, and DoD / defense-aerospace deployments.

Contact ack@octid.io for precision-mode access — see PATENT-NOTICE.md.

Two new MCP tools (total now 19, up from 17)

• osmp_eml_evaluate(chain_name, values) — evaluate a pre-built EML chain at input value(s)
• osmp_eml_corpus_lookup(chain_name) — list or inspect the 20 pre-verified chains

Attribution

Built on the universal binary operator eml(x, y) = exp(x) − ln(y) introduced by Andrzej Odrzywołek (Jagiellonian University, arXiv:2603.21852, March 2026). The operator itself is not claimed; the present work covers the transmission, encoding, and apparatus layer distinct from the operator.

Commercial services

Three request-gated services are available under commercial license (see PATENT-NOTICE.md):

• Omega namespace extensions — custom opcode registration for specialized domains
• MDR certification — authoritative namespace mapping for regulated deployments
• UBOT precision mode — correctly-rounded evaluator for audit-grade applications

v2.0.0

OSMP v2.0.0 — Cloudless Sky

Breaking Changes

• v15 Dictionary (352 opcodes): 24 opcode renames for improved cross-model readability. Existing SAL instructions using renamed opcodes (B:BA, B:BS, B:L, E:OBS, F:PRO, M:A, M:MA, Y:PROMOTE, Y:STAT, Z:CAP, and others) must be updated. Full rename table in protocol/OSMP-semantic-dictionary-v15.csv.
• ADJ meta-verb opcodes removed: A:ADJ, O:ADJ, R:ADJ, Z:ADJ removed per Principle 3 (no meta-verb opcodes). Operations expressed through slot values and delta glyphs instead.

New: Deterministic NL-to-SAL Composition (All 3 SDKs)

• SALComposer: deterministic pipeline composes SAL from natural language without inference. Generation index with 358 phrase triggers (318 auto-generated from ASD definitions + 40 curated). Confidence gate prevents false positives. BAEL byte pre-check. 95.7% opcode coverage on the full 352-opcode dictionary. 98.6% with LLM fallback.
• Ported to all three SDKs: Python (SALComposer), TypeScript (SALComposer), Go (Composer). Same pipeline, same results, same generation index.
• MCP tools: osmp_compose (NL to SAL), osmp_macro_list, osmp_macro_invoke. 17 tools total.
• Composition tested across 3 paths: deterministic tool (91.7%) outperforms frontier LLMs with full doctrine (77-81%).

New: Cross-Model Composition Test Suite

Six test scripts for measuring composition quality: deterministic sweep, three-path comparison, agent roundtrip, panel validation, panel discovery, full dictionary sweep (352 opcodes x 3 composition paths).

New Features

• ADR-004 Dictionary Basis Manifest: SAIL intern table is now a pure function of an ordered, content-addressed basis. FNP extended-form ADV (0x81) exchanges 8-byte basis fingerprints. Sessions grade to ESTABLISHED_SAIL or ESTABLISHED_SAL_ONLY based on basis agreement. Prevents silent SAIL misdecode between nodes with different dictionary loadouts. Implemented across Python, TypeScript, Go.
• MacroRegistry: Pre-validated SAL instruction chain templates. Register, expand with slot-fill, encode in compact or expanded wire format. Consequence class inheritance from chain. 16 Meshtastic macros shipped (DeviceMetrics, EnvironmentMetrics, AirQuality, Power, Health, LocalStats, Position, NodeInfo, Alert, Traceroute, Waypoint, threshold rules, MEDEVAC).
• ADR-005: Behavioral vs actuator command layers in R namespace. R:ACC/R:THR and R:DECEL/R:BRK paired entries for motion commands spanning planning and control layers.
• 11 new opcodes: A:CMPLY, A:PERM, G:DOP, Q:ANL, Q:FB, Q:JDG, Q:RPRT, R:ACC, R:THR, R:DECEL, R:BRK.

Improved: Bridge and Decode

• Bridge receiver parses [SAL: ...] wrapper from model responses
• decode_natural_language handles all chain operators, outputs domain context labels and readable NL
• Bridge annotation quality improved for acquisition seeding

Spec Updates

• Principle 3: No meta-verb opcodes (Section 12.3)
• Principle 4: Namespace-mnemonic alignment (Section 12.3)
• Composition Rule 10: Meta-verb prohibition (Section 12.5)
• Section 3.6: SAIL bijection anchored to basis equality
• Sections 9.1-9.3: Extended-form ADV/ACK, basis fingerprint computation
• Section 9.5: State machine updated (ESTABLISHED_SAIL, ESTABLISHED_SAL_ONLY)
• Section 9.8: Dictionary Basis Manifest specification

Bug Fixes

• Finding 2: ICD-10 code dot-normalization in MCP resolver (J93.0 now resolves)
• Finding 49: Go SAIL encoder I:section-sign (U+00A7) character class fix
• Finding 17: Stale opcode count references corrected
• Cross-SDK test runner paths fixed

Infrastructure

• gen_asd.py regenerates TypeScript and Go ASD tables from canonical Python source
• ASD drift check clean across all three SDKs
• Cross-SDK wire compatibility: 86/86 Python, 86/86 TypeScript, 86/86 Go
• 624 Python tests passing

OSMP v1.0.1 - Cloudless Sky

OSMP (Octid Semantic Mesh Protocol) v1.0.1. Tier 1 developer experience, SALBridge propagation, SAIL binary wire codecs, SEC security envelope, Rule 8 regulatory dependency grammar, package split. Patent pending, priority date March 17, 2026. Apache 2.0 with express patent grant.

Developer Experience

• Tier 1 API across all three SDKs: from osmp import encode, decode (Python), import { encode, decode } (TypeScript), osmp.Encode() / osmp.Decode() (Go). Three lines, zero setup, zero dependencies.
• Package split: pip install osmp is the standalone SDK. pip install osmp-mcp is the MCP server. The SDK has zero dependencies beyond Python stdlib. MCP wraps the SDK, not the other way around.
• PyPI: osmp v2.0.1 (new package), osmp-mcp v1.0.26
• Tier 2 class-based API (from osmp.core import OSMP) for advanced configuration
• KNOWN-ISSUES.md documents platform-specific install notes (Termux, Raspberry Pi, constrained hardware)

SALBridge: Language Propagation by Contact

• SALBridge shipped in all three SDKs. OSMP spreads by contact, not installation.
• FNP state machine extended: IDLE, ADV_SENT, ESTABLISHED, SYNC_NEEDED, FALLBACK (non-OSMP peer), ACQUIRED (peer learned SAL through context exposure)
• Bridge annotates outbound SAL with natural language equivalents, seeding the remote agent's context window with SAL patterns
• Monitors inbound messages for valid SAL fragments. When the remote agent starts producing valid SAL (few-shot acquisition), transitions to ACQUIRED and sends pure SAL
• Regression detection: ACQUIRED peers that stop producing valid SAL drop back to FALLBACK
• Comparison logging: every bridged message records SAL bytes vs NL bytes for side-by-side measurement
• from osmp import bridge -- Python factory function for zero-setup bridge creation

Protocol

• Adaptive Shared Dictionary (ASD) v14: 342 opcodes across 26 namespaces (26 new opcodes in Autonomous Ops MDR extension, runtime-loaded)
• SAIL (Semantic Assembly Isomorphic Language): Binary wire encoding, isomorphic to SAL. Bijective 1:1 mapping. Compose and debug in SAL, deploy in SAIL, decompile back to SAL for inspection. Wire codecs shipped in all three SDKs.
• SEC Security Envelope: Node ID + monotonic sequence counter + AEAD tag + Ed25519 signature. 87 bytes fixed overhead. Mesh authentication with no certificate authority.
• Four-mode wire architecture: SAL/SAIL x Unsigned/SEC. BAEL selects automatically based on channel capacity and consequence class.
• Rule 8 -- Regulatory dependency grammar: REQUIRES rules as SAL expressions, evaluated within the SAL framework. Conjunctive prerequisites supported (A AND B OR C AND D). 27 rules in Autonomous Ops MDR corpus. Shipped in all three SDKs.
• Six-category glyph architecture, Overflow Protocol (OP), BAEL floor guarantee, FNP handshake, ADP dictionary synchronization, R:ESTOP hard exception, SAL Usage Doctrine v2.2 -- all unchanged from v1.0.0.
