Track validated patch producer dependencies

[flyingrobots]

Dependency

Completed producer chain:

• Compile basis-bound validated workspace patch requests edict#178 — closed; compiler-owned basis-bound patch request and independent Core-to-Target derivation.
• Execute basis-bound validated workspace patches echo#711 — closed; generic validated-patch admission, execution, settlement, reconciliation, recovery, and replay.

Review-discovered producer blockers:

• Bind workspace patch requests to real schema artifacts edict#180 — open; replace sentinel patch schema identities with real compiler-owned schema artifacts.
• Persist filesystem WAL writer-epoch fencing across host restarts echo#714 — open; persist and recover filesystem WAL writer-epoch fencing across host restarts.

Blocked target:

• Prove basis-bound validated patch application #11 — implementation is open in PR Prove basis-bound validated patch application #24; consumer hardening may proceed, but merge waits for both producer contracts.

Current status: the composed write witness is locally green. It must not manufacture schema artifacts or reconstruct writer-epoch state in Hello Echo. Native blocked by relationships are recorded through GraphQL.

Completion rule

Close as completed when Edict #180 and Echo #714 are closed, hello-echo#11 consumes their merged contracts, and PR #24 or its successor merges.
