 - [ ] W1-A residuals (security, accepted, none exploitable from outside the user's own files): ReDoS is size-bounded only (`(a+)+$` in `~/.claude/model-router.json` + a 4 KB paste hangs the hook; fix = nested-quantifier rejection or a far lower scan cap); `stat().size` trusted (FIFO/device path in ~/.claude); unrestricted `models`/`agents`/`skills` KEYS echoed raw in logs (log flood); `agentId` read from the flat tool event (engine strip unverified); 5 closures without a kit test (no fs in the kit, LRN-206); "nothing routed" catch text after a state write.
 - [x] W1-B1 floor precedence (contract `2026-10-08-model-router-floor-1835`, 2026-10-09): `ultrathink` + typed `/effort-<l>` = the main turn's default AND minimum (r2 after 3 lenses: a pure floor made /effort-low a no-op); one helper `mainEffort`; per-axis precedence; mid-turn prompt floors now + next turn; `"enabled": false` per machine, kept across /clear and failed reload; typed slash attested. 30 tests; verifier CONFORME 6/6 (after 1 gap round); security PASS ×2
 - [ ] W1-B1 residuals (security 2026-10-09, accepted): first-load failure of the override falls to defaults (`enabled: true`); non-boolean `enabled` drops to the default on reload; `skill.prompt` preload guard is a heuristic (`loops.size > 0`; a preload during spawn or a non-composer `/effort-*` while idle still writes the floor); marker not bound to a valid level; `/route reload` answers "config reloaded" even when the previous config was kept; transient missing override lifts a config-set off; `String(err)` of a JSON parse in the local log. Display: `/route show` folds the floor into the effort while off; model-axis text with a model-only sticky and the switch on.
-- [ ] W1-B2 wiring (contract `2026-10-08-model-router-wiring-1835`): tracked symlink `skills/model-router` → `../mods/model-router` (loads as `@skills-dir`; PLUGIN_DIRS dropped: absolute paths in tracked settings), `.gitignore` engine-laid files, `lib/tests/mods.test.sh`, doctor `── Mods ──`, CLAUDE.md `## mods/`; then doc-sync (README/USAGE/CHANGELOG), live swap (remove the hot-reload link, `/reload-plugins`), BDR-115 amendment
+- [x] W1-B2 wiring (contract `2026-10-08-model-router-wiring-1835`, 2026-10-09): tracked symlink `skills/model-router` → `../mods/model-router` loads as `model-router@skills-dir` (fresh-process `claude plugin list --json` proves it), `.gitignore` `mods/*/tsconfig.json`, `lib/tests/mods.test.sh` (4 checks, capability probe, bounded, SKIP), doctor `── Mods ──` fail-soft, CLAUDE.md `## mods/`. Plan r2 from 3 lenses (5 MAJOR), feater DONE, gap round (4b label + unbounded probe), verifier CONFORME 8/8, security PASS
+- [ ] W1-B2 residuals (accepted): `claude plugin <unknown> --help` returns 0 → the suite's capability probe can pass on a CLI without `plugin test` and then FAIL instead of SKIP (fail-closed; fix = grep the probe output for the test usage line); doctor `claude plugin list --json` unbounded; doctor `echo -e` helpers interpolate `$_mod` (tracked folder names only); fallback timeout guard orphans grandchildren (only without coreutils timeout); `update-all.sh` runs `claude plugin update` over `@skills-dir` → one recurring warn (needs an update-all edit)
+- [ ] W1 close-out: doc-sync (README / USAGE / CHANGELOG), live swap (remove the hot-reload link in `~/.claude/dev-mods/<session>/`, user runs `/reload-plugins`), BDR-115 amendment (loading = skills-dir link; floor semantics), journal
 - [ ] W2 migration: 15 skills off `Skill(effort-*)`, remove shifters + effort-pins + model-gate, census repointed, docs
 - [ ] W3 optional: step heuristics, haiku classifier, quota-aware downgrade, A/B
