validate-provenance.sh matched Contributing files only as a single inline
line beginning "- **Contributing files:**". Seven skills write it as a
bare "**Contributing files:**" heading above a bullet list, so
parse_contributing_files returned None and checks 4 (contributing file
exists) and 5 (bidirectional source_keys) silently verified nothing on
git-branches, git-remotes, git-submodules, git-workflow, git-worktrees,
gitea-files and gitea-releases.
Those are among the skills this branch changed most — git-branches alone
gained five reference files — and the retrofit's mandatory sources.md
collateral went in unchecked. Demonstrated rather than argued: planting a
nonexistent contributing path in git-remotes yields 0 findings under the
old parser and 1 FAIL under the new one.
Both forms are now accepted. The bullet form is parsed per bullet rather
than by splitting a joined value, because its per-file notes contain
commas that would otherwise be read as path separators. The return type
becomes a list of note-stripped paths, with "(none)" as an empty list and
an absent entry as None, so the two callers no longer re-split a string.
Applied to agent-audit's copy as well. No agent ships a sources.md today,
so it is latent there, but it is the same defect.
This is a third gate blind spot alongside #117 and #118, and was unfiled.
One real defect surfaced immediately and is fixed separately.
Refs #99
Add validate-provenance.sh and validate-provenance.bats to enforce the
sources provenance chain introduced by skill-author. Eight checks cover
slug cross-references, Contributing files existence, bidirectional
source_keys linkage, Research doc: field presence, and upstream research
doc alignment (forward INFO, reverse FAIL). Adds a new Provenance report
dimension and INFO finding level (observational, exit-0, counted
separately as · P info in the result block).
