feat: add the declared-fact registry and drift audit - #369
Conversation
Five toolchain facts (Xcode, macOS runner image, JDK, Bun, Godot) were each declared in 4-16 files, and every incident on 2026-08-20 was one of those copies lagging a bump: release-godot.yml alone on macos-15, the Godot example project alone on 4.5. scripts/facts.mjs now declares each fact once with named roles (current vs minimum lets 4.7.1-stable and 4.3-stable coexist), and scripts/audit-facts.mjs scans for every occurrence rather than enumerating sites — an unlisted site cannot drift silently, a bumped registry fails every stale copy, and a dead declared value fails too. project.godot's feature tag is derived from the current Godot version instead of being pinned separately. Every fact ships with a planted-violation test, including replays of both incidents; the parity audit's twelve scalar pin needles move out so each fact has one owner. Model, authority direction, boundaries, and limits (agreement is not correctness — supported_platforms was consistent and wrong) are documented in knowledge/internal/08-fact-graph.md.

The audit validates scanned occurrences and derived values, runs through npm and CI, includes planted-violation tests, and adds documentation and repository references. ChangesFact Graph audit
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds a declared-fact audit, but valid .yaml workflows can still bypass it and the documentation currently promises broader coverage than the scanner provides, allowing some stale declarations to go undetected. This is a bounded merge-readiness risk requiring explicit owner awareness or follow-up, not a release-blocking runtime issue. Sequence Diagram(s)sequenceDiagram

its guarantee to declarations covered by scripts/audit-facts.mjs through
scanner.files and scanner.pattern, and document that unlisted files or
uncaptured declarations are outside audit coverage. Regenerate

In `@scripts/facts.mjs`:
- Line 12: Update scripts/facts.mjs lines 12-12 so WORKFLOWS matches both .yml
and .yaml workflow files, and update scripts/audit-facts.mjs lines 18-25 to
expand and filter both extensions. Ensure the existing audit covers Xcode,
macOS, JDK, Bun, and Godot values in either workflow format.

Hyo asked for the introduction to carry no side effects on existing systems, so the parity audit keeps its twelve scalar pin needles and both guards run side by side — they compare against the same files, so they cannot disagree, at the cost of one extra touchpoint per bump until the opt-in consolidation phase. The whole system now disables by removing a single CI step: everything else is new files and additive doc rows. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
bun run graph:impact <fact> answers 'what does bumping this touch' before the work starts: declaring files with line numbers, derived declarations, and the CI jobs those files trigger — computed with the same selectJobs model the path-filter audit already proves against CI, so the answer cannot drift from what CI actually does. The audit and the query share one scanner (scanFact), so they cannot disagree about what exists either. Read-only; still nothing outside the additive tool surface.

Added the read-only impact query in Two sharing decisions keep it honest: the query and the audit use one scanner ( |
GitHub Actions loads both extensions, so a future .yaml workflow could declare a toolchain value the scanner never sees — the silent-pass class this design exists to prevent. The directory lister is injectable so the test can plant a phantom .yaml without touching the real tree. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
CodeRabbit flagged that the guarantee reads wider than it is — a declaration in a file no scanner reads is invisible — and the thread was auto-resolved as outdated by an adjacent edit before it was addressed. Verification for this head also replayed the audit against real history: the incident tree (e814bea) yields exactly its three true findings, the pre-migration tree (f51aab3) yields twenty, aligned main yields zero.

Introduces fact-graph engineering for cross-cutting scalar declarations, per today's discussion. Design doc:
knowledge/internal/08-fact-graph.md.Why
Every incident on 2026-08-20 was the same shape — one copy of a widely-declared fact lagging a bump:
release-godot.ymlalone onmacos-15(9-minute queue mid-release)Example/project.godoton 4.5 while everything pinned 4.7.1Design — and the side effect it avoids
The obvious shape (a graph of fact→site edges) has a fatal side effect: the site list itself drifts, and an unlisted site passes silently. So there is no site list. Each fact declares its values with named roles and a scanner pattern; the audit requires:
Bumps become atomic in either direction. Named roles let
4.7.1-stable(current) and4.3-stable(minimum) coexist in the same workflows without a finding, which is also the escape hatch for deliberate divergence like Node 20/24.DERIVEDrelations compute one declaration from another —project.godot's"4.7"feature tag derives fromgodot.version.currentinstead of being pinned separately.Ownership dedupe
The parity audit pinned
runs-on: macos-26/XCODE_VERSION: 26.6as needles in six blocks — those exact needles were hand-edited three times today during the image work. They move out (12 lines); structural needles (setup-xcode presence, job names,APP_STORE_SDK_VERSION) stay. One fact, one owner.Guard verification
Per this repo's fresh lesson (the release-sync guard shipped unable to catch its own bug), every fact ships with a planted-violation test: the suite edits real files in memory and asserts the audit reports the drift — including byte-for-byte replays of both of today's incidents. 7 tests.
Limits (documented)
Agreement is not correctness:
supported_platformswas consistent across all four copies and every copy was wrong. This catches drift between declarations, nothing more.Wiring
bun run audit:facts, CI step in the audit-parity job, AGENTS.md quick-reference row, agent context recompiled. Roadmap phases 2–3 (absorbing scalar parity needles, deriving CI path filters) are documented, not implemented.No device regression required: repository automation and documentation only — no
packages/,libraries/runtime code, or store behavior touched (the parity-audit edit removes needles only).Summary by CodeRabbit
