…d (T7-12 emitter slice) source-os is a downstream emitter for the Tranche 7 Model Plane. This adds the smallest real slice that proves source-os can emit a spec-conformant, hash-chained InferenceReceipt natively when a completion finishes, into the estate's single ledger (SEAM-011: no local-only ledger). Consume-not-fork: the canonical emitter and schema are vendored BYTE-VERBATIM from prophet-platform apps/receipt-gateway (provenance + source sha256 in modules/model-plane/tools/VENDOR.md and the schema $comment). The only source-os code is inferenced_shim.py, the serving-path caller — it delegates all chaining to emit_receipt() and re-implements nothing. Teeth (.github/workflows/model-plane-receipts.yml): a produced receipt validates against InferenceReceipt.schema.json and chains (prevHash continuity); a tampered entry and a local-only (unchained) entry are both rejected; and the vendored emitter is asserted to match the canonical sha256 (consume-not-fork guard). The full daemon set (T7-9..15) and seam-registry (T7-20) remain; see the T7 follow-up issue. docs/model-plane/architecture.md (T7-9 stub) tracks status.

Model Plane —
inferencedreceipt emitter shim (Tranche 7)source-os is a downstream emitter for the Model Plane (epic SourceOS-Linux/sourceos-spec#241). This lands the smallest real slice that proves source-os can emit a spec-conformant, hash-chained
InferenceReceiptnatively when a completion finishes, into the estate's single ledger (SEAM-011: a local-only ledger is not permitted).The full serving daemon
inferenced(T7-12) and the rest of the daemon set are blocker-laden (HellGraph ledger service, base-model licensing, credentials) and are not built here — this is the emitter half only.Consume-not-fork
modules/model-plane/tools/inference_receipt_emitter.py— the canonical emitter, vendored byte-verbatim fromSocioProphet/prophet-platform apps/receipt-gateway(commitabd98805, sha2566881246b…; provenance intools/VENDOR.md). CI asserts the sha still matches — divergence fails the build.modules/model-plane/schemas/model-plane/InferenceReceipt.schema.json— schema vendored verbatim (provenance in$comment).modules/model-plane/inferenced_shim.py— the serving-path caller. Given the content-addressed base-model digest + the completion's input/output, it appends an on-device receipt viaemit_receipt(). It re-implements no chaining.Teeth —
