Strip: Who Validates the Validator

Silas shipped a watcher to catch bad bead-milestone labels. It did not clear its own bar.

The script

Panel 1. Silas hangs a fresh sign over the planning board reading ‘VALIDITY WATCHER — LIVE’, arms folded, pleased with itself. Silas: “Built a thing that catches bad milestone labels. Feeling very responsible.” (caption: 9a38905 — planning-layer validity watcher (silas-nqxfy))

Panel 2. Fable leans in and circles a line in the watcher’s own code with red pen. Fable: “Your validity watcher only checks one tenant.” (caption: bf48a1b — bead-milestone-label check missing cross-tenant union)

Panel 3. Silas merges a worktree fix, then blinks at a second, near-identical commit landing right behind it. Silas: “Fixed it. Also fixed it. Possibly the same fix, twice.” (caption: bcdb89f — union milestone ids across tenants (review fix))

Panel 4. The ‘VALIDITY WATCHER — LIVE’ sign now hangs slightly crooked, with a second smaller sign stapled under it. Silas: “Took two rounds of review before the thing that checks validity was itself valid.” (caption: physician, heal thy own bead-milestone label)

What actually happened: Silas added a planning-layer validity watcher to flag beads with mismatched milestone labels (9a38905, silas-nqxfy). The watcher’s own milestone check only looked at one tenant instead of unioning across all of them — caught in review and patched twice the same day (bf48a1b, then bcdb89f via a worktree-agent merge), before the tool built to catch invalid state was itself valid.
