🔵 Needs a closer look
It introduces substantial new measurement/export plumbing and retry/plan invariants across multiple subsystems, which warrants final human review despite strong test coverage.
Pull request overview
Aligns Scout’s replay/measurement pipeline with the released PAA worker-attribution + operating-record contracts by capturing controlled worker manifests, exporting PAA-shaped evidence/operating envelopes, and updating reference evidence + docs to match.
Changes:
- Bump PAA dependencies to
paa-runtime==0.4.0andpaa-contracts==0.2.0. - Add a new shadow-only
reply_draftPAA task declaration plus ascout feedback report --format paa-jsonexporter that emits operating records, evidence records, and content-addressed provenance. - Capture and pin full worker configuration in replay plans/evidence, preserve trace-derived costs even on candidate output validation failure, and reject configuration drift on retry.

Addressed in a03d880. Removed the redundant worker-only comparison. The full current_evidence comparison remains the single drift check and includes worker_configuration before attempt execution. Updated the regression test to expect that diagnostic while retaining the assertion that configuration drift causes no database writes. Validation: 233 targeted replay, reporting, declaration, and reference tests passed; Ruff, mypy, and reference-evidence verification passed.
Summary
Third PR in the PAA economic-fitness sequence, following the released worker-attribution and operating-record contracts in RankOneLabs/paa#11.
paa-runtime==0.4.0andpaa-contracts==0.2.0.reply_drafttask with an advisory correction-distance evaluator. Existing surfacing/canonical task declarations and authority behavior are unchanged; the new task has no reachable promotion from its initial manual position.scout feedback report --format paa-json: released evidence and operating-record envelopes, content-addressed provenance, per-variant population/coverage, and one accounting record per attempt, including failed/superseded attempts.Deliberate boundaries
This is Scout schema alignment and measurement support, not a completed economic-fitness experiment. No paid sweep, production-data changes, configuration adoption, or authority transition was performed.
Acceptance rules, effective cost, and operating decisions remain unset. Before the real experiment, declare its Phase 1 qualification rule, replay acceptance rule, populations/accounting boundaries, and full-pipeline provenance. Phase 1 costs/counts must not enter a replay ratio.
Historical attempts without the captured worker manifest remain readable in existing reports but are not backfilled into attributed PAA records. Repriced exports are alternative accounting snapshots, not additional charges. Exports contain internal provenance and require review before publication.
