# 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.
