+## The provenance corpus sweep (ADR-0028)
+
+`check-provenance-corpus` runs `validate-provenance.sh` over every real
+`plugins/*/.apm/skills/*/` directory that has a `references/sources.md`, and fails on any FAIL. The set
+is discovered by glob, not counted, so a new skill is covered the moment it grows a `sources.md`, and
+**discovering zero skills is an error, not a pass**.
+
+The hook exists because nothing else ran the validator over the real corpus.
+`check-scope-walkup-sync` invokes it only against synthetic `mktemp` fixtures, and `factory-audit`'s
+bats suite does the same. So a `Research doc:` naming the wrong file, or a slug absent from its
+Research registry, could only be found by hand-running the validator in a loop. That is how 36
+mismatches (#121) reported INFO while every gate stayed green. ADR-0028 promotes "the check ran and
+found a mismatch" from INFO to FAIL; without a caller across the corpus that FAIL tier would be inert.
+
+It reuses the validators' exit contract (see
+[the three exit tiers](#the-three-exit-tiers-of-factory-audits-validators)) and keeps the tiers apart:
+
+| Exit | Means |
+|---|---|
+| **0** | every skill validated. INFO-only findings are printed, never swallowed |
+| **1** | at least one skill FAILed. The summary line names the failing skills |
+| **2** | the gate could not run: the validator is missing, a skill's validator run exited 2 ("not auditable"), or no skill with a `references/sources.md` was found |
+
+A validator exit 2 is reported as a gate error, not as a FAIL about that skill: it says the audit never
+happened, and the skill has not been shown to be wrong.
+
+An unresolvable `Research doc:` path stays INFO by design, because a deployed copy of a skill outside
+this repo will not carry the research docs (see `skill-file-structure.md`'s `sources.md` exemption).
+This repo's own corpus is audited from the authoring source, where every path resolves, so an INFO
+printed here is worth reading. Needs no network; needs `python3`, which the validator's own preflight
+names.
