# Artifact Contract Auditor This Skill measures **coverage**: whether files promised by Units and the locked Pipeline exist at the point they are required. It does not replace the deeper Attempt, Manifest, Artifact-hash, and ledger checks in `pipeline.py audit`. ## Inputs - `UNITS.csv`. - `PIPELINE.lock.md`. - The locked `pipelines/*.pipeline.md` target-Artifact contract. ## Outputs - `output/CONTRACT_REPORT.md`. ## Steps ### 1. Resolve the active contracts Read `PIPELINE.lock.md`, resolve the Pipeline inside this repository, and parse `UNITS.csv`. Treat an invalid lock or malformed Unit table as a reportable contract failure rather than guessing another Workflow. Completion criterion: one Pipeline contract and one readable Unit table are bound to the audit. ### 2. Check completed Unit outputs For every `DONE` Unit, verify each required output exists. Outputs prefixed with `?` are optional. A missing required output is Unit-level contract drift even when the Pipeline is still running. Completion criterion: every `DONE` Unit is classified as output-complete or is listed with each missing required path. ### 3. Check final Pipeline targets when applicable Determine whether all Units are terminal (`DONE` or `SKIP`). Only then require every non-optional target Artifact declared by the Pipeline. During a partial Run, report missing final targets as expected rather than failures. Completion criterion: final-target completeness is evaluated against the actual Run phase...
