Admission accepts only a receipt ID from untrusted model output. The owner API first verifies the exact authenticated OpenCode-handoff manifest digest, canonical envelope bytes, reviewed producer-to-kind policy, and repository/head/workflow/run/attempt identity before it can construct an immutable typed index; admission then reconstructs each canonical artifact and verifies time/claim/artifact identity. The version-2 manifest now binds a separate producer-authenticated `ClaimEvidenceRequirement` containing the exact claim, independently required evidence kind, and `context` or `finding` publication authority. Raw current-head source lines are context only: they are withheld from finding-reference prompts and cannot publish a finding or `request_changes`; an explicitly producer-authorized source finding remains usable and retains exact path/line checks. Finding-free model `request_changes` and `blocked` verdicts cannot bypass receipt admission to publish a vacuous blocking review. Requirement/receipt kind mismatch, fixed-artifact semantic substitution, caller-supplied receipt dictionaries, model self-classification, stale identities, cross-kind receipts, marker-only sandbox output, noncanonical artifact bytes, and expired receipts fail closed before the GitHub publisher.

Caller-supplied `activated_at` and `invoked_at` remain event evidence and cannot backdate current authorization. +- Authentic activations and invocation receipts are bound to the exact admitted source snapshot that issued them; matching artifact bytes or product/role/policy fields do not authorize cross-admission replay. +- Replay equality retains only `noema.external_extension.invocation_envelope:v1:sha256:`, computed from a fixed-order canonical tuple of every semantic invocation field. The retained value is domain-separated and versioned; plaintext normalized invocation JSON is not retained for replay equality. +- SHA-256 is delegated to the Worker runtime's Web Crypto `crypto.subtle.digest("SHA-256", ...)`. Noema owns only the domain/version prefix, canonical field order, replay-state lifecycle, and fail-closed interpretation.

Digest-provider failure is normalized into the domain error and fails closed. +- Replay-digest state is process-local and keyed by receipt lifetime. Process restart discards that replay authority and therefore fails closed rather than migrating or reconstructing an unverifiable old plaintext/digest binding. A future canonicalization or digest change requires a new explicit version; old in-memory bindings are not silently reinterpreted. +- `developer_assist` admits no filesystem, network, process, secret, or MCP capabilities. Provider keys and broad GitHub authority are forbidden. +- Product-scoped activation cannot use another product's approval. `approved_for_pilot` is not invocation authority. +- Expired, suspended, superseded, rejected, or rollback-marked extensions cannot be invoked. +- Catalog drift after admission cannot silently update an active extension. +- Duplicate activation and invocation events are idempotent replay; conflicting retained events fail closed. +- An invocation timestamp cannot predate the issued activation it cites; descriptor-window validation, runtime-current validity, and activation-to-invocation causal order are separate invariants. +- Plugin instructions cannot promote observed content into trusted policy or new capability. +- Product-runtime mode cannot execute a Claude plugin wrapper. +- Invocation receipts contain only identity fields and must not carry secrets, raw product data, or hidden reasoning. + +The existing catalog/scanner/admission/activation/invocation implementation remains behind an internal Tool / Capability core. Exact admission issuance/replay provenance is owned once by that core. The public port adds the Noema Policy / Approval ACL, current-time authorization, admission-bound live authority, and request-envelope replay digest without copying AppGuardrail, quarantine, EgressWeave, Keyverse, or contextual-orchestrator authority. Policy / Approval must be supplied through an explicit immutable trust input; repository source does not mint a pilot grant from placeholder owner-policy digests. This local ACL remains a provisional Noema boundary and is not a substitute for a future released shared contract or live pilot approval. + +The replay digest follows SHA-256 as specified by FIPS 180-4. The fixed field order and explicit domain/version prefix are Noema application-level canonicalization rules, not a new hash algorithm. Runtime conformance is exercised against standard short, padding-boundary/multi-block, and million-byte SHA-256 vectors in addition to the application-domain known vector and semantic-field sensitivity tests. No Node compatibility flag and no new cryptographic dependency are introduced by this decision. + +This port is a test double and Anti-Corruption Layer until an immutable `context-graph-contracts` release exists. Noema does not copy plugin source, install the marketplace, or treat Anthropic review as CWL trust. + +The decision follows least privilege and complete mediation (Saltzer & Schroeder, 1975), fail-closed verification of untrusted software components (National Institute of Standards and Technology, 2022), and the current SHA-256 Secure Hash Standard (National Institute of Standards and Technology, 2015). Cloudflare Workers documents Web Crypto through `crypto.subtle` and an asynchronous digest operation; that runtime interface is used as the primitive boundary rather than duplicating the algorithm in Noema. + +## Consequences + +Operators can reject hostile plugin metadata, self-asserted approval grants, backdated attempts to reuse expired authority, cross-admission replay, and divergent replay envelopes deterministically without waiting for foreign GA. Invocation now depends on immutable source/scanner identity, an explicitly supplied Noema product/role/time policy grant, current runtime time being inside that grant, exact admission provenance, and a fixed-width replay digest. Revoking, changing, expiring, replacing, or omitting the applicable authority prevents new activation or invocation. + +The replay WeakMap no longer extends the lifetime of reversible request plaintext merely to support equality. A process restart intentionally loses replay-digest authority; the safe recovery behavior is to reject retained receipts whose local binding no longer exists rather than recreate trust from receipt fields alone. There is no plaintext-data migration path for this candidate because the prior representation was never protected or released. + +The public success/replay path is now asynchronous at the cryptographic publication boundary. Callers must await the returned promise before consuming an accepted receipt. Pre-digest validation errors remain synchronous so malformed or unauthorized work is rejected before cryptographic work is scheduled.
