+# DEBUG: Phase 9 verification stale loop
+
+**Discovered:** 2026-09-28 during `$gsd-progress`
+**Status:** resolved
+**Goal:** stop gsd-progress routing back to Phase 9 after execute-phase 09
+
+## Symptoms
+
+- `$gsd-progress` kept routing to `$gsd-execute-phase 09` with `verification.status=stale`
+- execute-phase 09 had already been run several times
+- No separate error; the progress report simply named Phase 9 again
+
+## Root Cause (two layers)
+
+**Layer 1 (2026-09-28, fixed in 1a878b3):** Phase 10.2 commit `5e50b16` moved 42 Phase 9-covered files under `modules/`. `09-VERIFICATION.md` still listed the old top-level paths, so `computeCoveredDigest` returned null and status was always stale.
+
+**Layer 2 (2026-10-05, the remaining loop):** After the paths were corrected and the report passed at HEAD `ba1aaef` (`9692315`), Phases 12.1, 12.2, 13 and 14 edited 25 of those same files (+3294/-217). The fingerprint then mismatched current bytes. That is GSD working as designed — later work on shared modules re-stales an earlier phase — not a missing-path bug. Progress always routes to the lowest-numbered incomplete phase, so 09 stayed in front of the later-phase queue.
+
+## Fix
+
+1. Confirmed every declared `covered_files` path exists (0 missing).
+2. Ran `scripts/check-phase9.sh --all` at summercms.go `104a1c9` / fonoteka.go `93b8b75` — passed.
+3. Recomputed `covered_digest` to `v2:sha256:c2f48f6ce04a5eed4788d745da45b1c1555a769df4feebfe88b9bbf671b634fb` and recorded the re-verification in `09-VERIFICATION.md`.
+
+## Verification
+
+`gsd_run query verification.status` on the Phase 9 directory returns `passed`.
+
+## Note
+
+Phases 10, 10.1, 10.2, 11, 11.1, 11.2 and 12 can still read `stale` for the same digest-drift reason. Closing 09 only unblocks the first slot of that cascade.
