Optimization implementation — 2026-09-05

Workplan: INFO-WP-0019. Registered State Hub UUID: b29261ba-c1e4-5533-8185-ab2d5b433685. Implements the local optimization recommendations from the timestamped scope assessment. Existing uncommitted changes were retained.

Delivered

• contracts.py: shared JSON Schema validation and Emission Cadence semantics; arbitrary YAML/JSON declaration review; duplicate source-ID detection robust to malformed field types; schema bindings for mapping artifacts.
• service.py: explicit ownership conflicts fail validation; reports describe coverage limits; capability operations respect the selected corpus root.
• maintenance.py: non-mutating comparison of generated projections, registry-derived scope inventory, deterministic content-addressed contract export, validation timestamp/revision/dirty-state/corpus-digest evidence, and repeated-read measurement.
• CLI commands: emission-review, validation-coverage, scope-inventory, check-generated, export-emission-contract, and benchmark-reads.
• Installed bench discovery and independently selected corpus root replace hardcoded workstation lookup. The narrow loader remains necessary because upstream initialization imports unrelated database integrations.
• make check, make check-generated, and make refresh expose maintenance workflows. State Hub refreshes work-record projections from source files.
• Consumption documentation defines portable installation, contract pinning, independent adoption evidence, and demand-led selection of future profiles/patterns. README and SCOPE describe the changes.

Verification

make check passed 36 tests in 22.42 seconds, verified 77 generated assets, and passed canon validation (76 artifacts/315 relationships) and Small-SaaS validation (15 payloads), both without errors or warnings.

Seven new tests cover malformed declarations, unsupported versions and duplicate IDs, stale/missing projections without source mutation, deterministic bundle bytes and corruption refusal, mapping schema enforcement, explicit ownership conflicts, report digest behavior, selected-root capability loading, and a missing schema producing a validation finding.

A fresh virtual environment under /tmp/itc-install-SOoIlF/ installed PyYAML 6.0.3, jsonschema 4.26.0 and their dependencies, plus locally built canon and bench wheels using --no-deps. With PYTHONPATH unset and an independent corpus copy, installed CLI inspection, canon validation, and emission review passed. The initial corpus copy omitted two demand provenance files; validation correctly reported them missing. Including demand/ completed the proof. Full transitive bench installation remains outside this narrow proof because its upstream metadata still names workstation paths. No sibling source files were changed.

Contract export produced:

dist/contracts/emission-cadence-0.1-972c0b6701d1693f6bb297a2feef34bcdb5ef04f3c906882e6f5e0afa5261e01.tar

The filename is its SHA-256. The manifest records schema, standard, and example hashes and the additional uniqueness check. The build output is gitignored; recreate it with export-emission-contract dist/contracts. This is a local distribution artifact, not remote release publication.

Ten uncached inspections measured median 788.05 ms, maximum 1241.92 ms on this workstation during concurrent verification. These measurements do not establish a production SLA. No cache was added without a workload and latency target. Ruff was unavailable; no lint result is claimed.

Remaining boundaries

T01–T05 are done; T06 waits for two independent source owners' implementation and consumer evidence. The workplan remains blocked rather than declaring draft promotion complete. No external messages or consumer writes were made. The original CARING calculus, complete concept extraction, comprehensive mapping metadata, and cross-version interoperability gaps are not claimed closed by this implementation; coverage output explicitly preserves these limits.

State Hub registration succeeded. Its consistency helper also commits/pushes its own generated consistency changes. Advisories include the documented INFO-WP convention conflicting with the registry's ITC-WP prefix, existing classification warnings, and intake-index lookup trouble. These do not prevent the new workplan and six tasks from being registered.

Final synchronization encountered two State Hub repository-query timeouts. The five completed task statuses and blocked workplan status were then updated and confirmed through their individual REST endpoints. WORK-RECORDS.md was regenerated using State Hub's own offline _generate_work_record_index renderer, preserving the file-authoritative projection. Progress receipt: deab32a8-7642-440c-896c-e37783084757. A full consistency sweep still needs re-running when the repository-query path recovers; registration and final task statuses have already been confirmed.
