+**Legacy violations cleared 2026-05-13**: the three previously-tracked
+`tools/hygiene/audit-*.sh` violations (`audit-lost-files.sh`,
+`audit-trajectories.sh`, `audit-backlog-items.sh`) have all been ported
+to `.ts`. The current `tools/hygiene/` directory is entirely
+Rule-0-compliant.
+
+**Remaining audit question (out of scope for Rule 0 itself)**: the Lior
+agent's `.gemini/service/install-lior-service.sh` +
+`.gemini/service/lior-loop.sh` live outside `tools/setup/`. They are
+install-graph by intent (Lior's launchd-equivalent service bootstrap)
+but the rule's "only `tools/setup/`" phrasing technically excludes
+them. Resolution is a separate design question — either expand the
+rule's allowed-path list to include agent-specific install-graph
+locations or port / relocate them under `tools/setup/`. Either way,
+NOT a "legacy violation" in the same sense as the cleared three.

+- CronList: live (`9ac08520`, `* * * * *`, sentinel `<<autonomous-loop>>`).
+- Since previous tick, PR #3046 (Otto-Desktop's B-0449 design pass) MERGED → `8077181`.
+- Main tip: `8077181 docs(backlog): B-0449 — bg-services slice 5 subscriber-agent design pass (#3046)`.

+## Speculative work picked
+
+Per never-be-idle: while #3047 CI was running, audited `.claude/rules/`
+for staleness related to this session's substrate-hygiene sweep. Found
+that `rule-0-no-sh-files.md` still listed three `tools/hygiene/audit-*.sh`
+files as "Legacy violations" owing a TS-port follow-up. All three have
+since been ported and the `.sh` files removed:
+
+| Was | Now |
+|---|---|
+| `tools/hygiene/audit-lost-files.sh` | `audit-lost-files.ts` ✓ |
+| `tools/hygiene/audit-trajectories.sh` | `audit-trajectories.ts` ✓ |
+| `tools/hygiene/audit-backlog-items.sh` | `audit-backlog-items.ts` ✓ |
+
+The "Legacy violations" callout was operationally stale documentation
+— exactly the failure-mode class the rest of this session's sweep
+addresses.

+`.gemini/service/install-lior-service.sh` + `.gemini/service/lior-loop.sh`
+live outside `tools/setup/` but are install-graph by intent (Lior's
+launchd-equivalent service bootstrap). Rule 0's "only `tools/setup/`"
+phrasing technically excludes them. Surfaced as a NOTE in the updated
+rule body rather than silently leaving the ambiguity. Resolution is a
+separate design question (expand allowed-path list vs port/relocate).
