+# Conformance, reproducible consumption, and maintenance
+
+Implements the optimization recommendations in
+`history/2026-09-05_002437+0200-scope-against-intent.md`.
+Reviewed against the current working tree; authorized by the operator on
+2026-09-05. Uses the AGENTS.md INFO-WP file convention.
+
+## Reusable conformance and coverage
+
+```task
+id: INFO-WP-0019-T01
+status: done
+priority: high
+state_hub_task_id: "abc0ed79-009f-5254-a2bf-4dcedd1925e9"
+```
+
+Extract shared schema validation and emission-cadence semantics into contract
+modules. Expose arbitrary declaration validation and explicit coverage through
+the CLI. Reject unsupported versions, malformed declarations, and duplicate
+source IDs. Enforce explicit ownership conflicts. Preserve all existing tests.
+
+## Reproducible contract bundle and adoption gate
+
+```task
+id: INFO-WP-0019-T02
+status: done
+priority: high
+state_hub_task_id: "1ec85dc5-5775-50b6-8066-ac839fd252c9"
+```
+
+Provide deterministic, content-addressed export of the cadence contract,
+schema, and example; refuse overwriting different contents. Define owner-authored
+adoption evidence requirements and keep draft promotion contingent on two
+independent implementations. Local examples must not count as adoption evidence.
+
+## Freshness and evidence
+
+```task
+id: INFO-WP-0019-T03
+status: done
+priority: high
+state_hub_task_id: "e4171772-50bf-58f6-9c87-8eddbef1caa5"
+```
+
+Add non-mutating generated-asset checks, reproducible scope inventory, and
+revision/time/source-digest evidence on validation reports. Refresh work-record
+projections via State Hub. Check stale and missing generated assets with tests.
+
+## Portable consumption
+
+```task
+id: INFO-WP-0019-T04
+status: done
+priority: medium
+state_hub_task_id: "e258d84d-d969-5032-baef-ae1060843319"
+```
+
+Remove hardcoded workstation dependency paths. Resolve an installed bench
+distribution and an explicit external corpus root. Prove wheel installation
+and commands from an unrelated directory. Document upstream packaging limits
+without changing sibling repositories.
+
+## Measure performance and verify implementation
+
+```task
+id: INFO-WP-0019-T05
+status: done
+priority: medium
+state_hub_task_id: "09a585e8-4c67-5143-bc3a-ae47623547ea"
+```
+
+Measure repeated reads before deciding whether caching is justified. Run all
+tests, canon/profile validation, generated freshness checks, and the clean
+installation proof. Update SCOPE/README and record evidence. Avoid speculative
+models or runtime expansion.
+
+## Independent consumer adoption
+
+```task
+id: INFO-WP-0019-T06
+status: wait
+priority: high
+state_hub_task_id: "b33aeb8c-ba7c-5094-9902-85565c1e721b"
+```
+
+Requires two source owners to provide independently implemented declarations
+and consumer results pinned to the contract digest. This repo can validate
+submitted evidence but cannot manufacture source ownership or deployed proof.
+No external messages or consumer changes are authorized by this workplan.
+Promotion remains blocked until that evidence arrives.
+
+## Implementation notes
+
+T01–T04 implemented in `contracts.py`, `maintenance.py`, `paths.py`, CLI,
+service integration, and `docs/canon-consumption.md`. Explicit mapping schema
+bindings and ownership checks improve coverage without claiming exhaustive
+semantic validation. The normal bench initializer imports unrelated database
+integrations; installed-module discovery retains the narrow adapter. Clean
+wheel consumption uses the documented explicit-dependency installation until
+the upstream owner separates reference-data packaging.
+
+Registration: State Hub workstream `b29261ba-c1e4-5533-8185-ab2d5b433685`.
+The consistency tool reports an INFO-WP/ITC-WP prefix advisory: this plan follows
+the explicit INFO-WP convention in AGENTS.md; existing plans and the registry
+use ITC-WP. This naming inconsistency does not prevent registration.
+
+## Verification — 2026-09-05
+
+`make check`: 36 tests passed (22.42 seconds); all 77 generated assets current;
+canon validation passed (76 artifacts, 315 relationships); Small-SaaS passed
+(15 payloads). Installed-wheel inspect, validation, and emission review passed
+from an unrelated directory with PYTHONPATH unset and a copied corpus.
+Ten uncached inspections measured median 788.05 ms, maximum 1241.92 ms;
+caching remains deferred pending a workload/latency requirement.
+
+Local implementation T01–T05 is complete. Overall status is blocked only on
+T06's independent owner evidence. See
+`history/2026-09-05_optimization-implementation.md` for artifacts and limitations.
