+The first call-site audit found a new canonical-promotion substitution in `epiphany-operator-snapshot from-status`: arbitrary edge JSON under `/tools/invocations` could be converted into canonical daemon-tool intent and receipt documents. That promotion is removed. The adapter writes only `operator_snapshot`, returns null tool intent/receipt fields, and states `runtime-spine-only` authority; the conversion helper is compiled only for tests. Forgery proof imported an `accepted` fake receipt and confirmed both canonical latest tool intent and receipt remained absent. See `notes/receipt-writer-provenance-audit-2026-07-12.md`. Next quarantine smoke writers, then inspect operator-run and daemon-supervisor evidence binding.

+# Receipt Writer Provenance Audit — 2026-07-12
+
+## Method
+
+Inventory every production call to `write_*receipt`, then ask whether the executable is the named owner, a bounded ingest/projection boundary, a test-only fixture, or a caller able to assert the result it records.
+
+## Classification
+
+- `epiphany-daemon-supervisor`: owner-aligned for scheduler, lifecycle, and daemon-poke receipts. It performs or observes the lifecycle operation it records.
+- `epiphany-eve-provider`: owner-aligned narrow provider receipt writer; verifies the pending intent targets its provider cluster.
+- `epiphany-operator-run`: owner-aligned for operator-run receipts and coordinator receipts derived from the run it executes.
+- smoke binaries and the `epiphany-verse-query smoke` arm: fixtures, not runtime evidence. They remain a quarantine risk if permitted to target canonical stores.
+- `epiphany-work` Weksa lowering: a lowering projection receipt, explicitly non-publication authority; no substitution confirmed in this pass.
+- `epiphany-operator-snapshot from-status`: **confirmed substitution and cut**. Arbitrary edge JSON under `/tools/invocations` could previously be converted into canonical daemon-tool intent and receipt documents. The snapshot adapter now writes the operator snapshot only; tool invocation fields return null and authority remains `runtime-spine-only`. The conversion helper is test-only.
+
+## Negative proof
+
+A forged operator-status artifact containing `intentId=forged-intent`, `receiptId=forged-receipt`, and `status=accepted` was imported. The operator snapshot was written, while canonical latest daemon-tool intent and receipt both remained absent.
+
+## Remaining scrutiny
+
+1. Quarantine smoke writers so they cannot target canonical stores.
+2. Inspect `epiphany-operator-run` receipt construction against actual subprocess/runtime evidence rather than command arguments.
+3. Inspect daemon-supervisor plan/rehearsal receipts separately from execution receipts so planning cannot masquerade as service mutation.
+4. Distill or remove dead public receipt constructors once every named provider executable exists.

Every confirmed caller/provider dual writer in that audit is cut from caller-facing production paths. Artifact-acceptance and metrics commands now surface admitted repo requests, report pending named owners, reject all acceptance/accounting result fields, and write no receipts.

   - `swarm-overview` is an Epiphany-local, renderer-neutral diagnostic projection over provider-owned typed state. It owns no lifecycle, discovery, composition, or mutation authority. Epiphany publishes clean provider-owned Eve surfaces; Odin may discover them; downstream lowerers and compositors remain outside Epiphany's concern.
   - Idunn owns daemon survival and service lifecycle physiology. Codex/operator sessions may inspect, generate runbooks, and route explicit operator authority, but keeping daemons alive belongs to Idunn-owned service lifecycle receipts, scheduler policy, audits, and aftercare. Do not let Self, diagnostic projections, or ad hoc wrapper summaries become a second daemon-keeper. Global tool readbacks for Self `service-health`, `service-policy-directory`, and `swarm-online-runbook` state `lifecycleOwner=Idunn` and `hostedBody=Epiphany` without service mutation or private-state exposure.
   - Use `notes/epiphany-cultmesh-dreaming-roadmap.md` as the design authority for distributed Epiphany dreaming. Public dreams are separately authored typed documents distributed through CultMesh/CultNet; private state remains local and cannot be shared by flipping a visibility flag. Foreign dreams are external thought weather until a reviewed local adoption receipt digests them into memory, planning, doctrine, or governance.
