- model-router mod, wave 0 spike (user ask: one mod routes model + effort per request, replaces effort-* shifters + pins). Plan `.claude/tasks/plans/2026-10-08-model-router-mod.md`, 4 decisions by AskUserQuestion (spike-first main-loop switch, `CLAUDE_CODE_PLUGIN_DIRS` load, migration wave 2, names model-router / route / /route), rule "pin = entry default, sub-tasks route finer".

Found: hook-side alias resolver stale (`sonnet` → `claude-sonnet-5`, 404; Agent tool enum resolves the same alias to 5-5) → mod writes full ids only. feature/model-router-mod open, nothing committed yet (plan + TODO + journal pending). - model-router mod, wave 0 spike (user ask: one mod routes model + effort per request, replaces effort-* shifters + pins).

- model-router wave 1-A (/feat, user go): mod built in `mods/model-router/` (4 files, 834 + 202 lines, 11 plugin tests). Plan r1 → r3: 3 challengers (simplicity CONCERNS, robustness CONCERNS(6), correctness FATAL(8)) + 1 confirmation CONCERNS(4); converged on: agents table = built-ins only in wave 1 (frontmatter stays single writer), agent model written once at spawn, explicit Agent params frozen per loop, every sub-agent write on its own loop, Skill bridge answers in the Skill tool's OUTPUT schema (string result refused → skill would load), config validated before merge, state in closure, `/route off`. feater DONE first pass; GATE 0 MET; verifier CONFORME 6/6; security PASS (4 MEDIUM + 5 LOW parked in TODO for user go). Commits b721c94 (mod) + e8ca713 (contract/plan). Override `~/.claude/model-router.json` {verbose:true} written (pass B). Doc-sync deferred to 1-B.

- [ ] W1 core mod in `mods/model-router/` (config, route tool, /route, agents, skills, prompt rules, visibility, tests, install) - [x] W1-A the mod in `mods/model-router/` (b721c94, contract `2026-10-08-model-router-w1a-1533`, plan r3): challenge 3 lenses + 1 confirmation (2 BLOCKER + 10 MAJOR closed by named changes), feater DONE first pass, GATE 0 MET 5/5, verifier CONFORME 6/6, security PASS (4 MEDIUM + 5 LOW reported, below)
- [ ] W1-A hardening (security report, user decision): `/route` command origin check (`composer` only); in-agent `route` must not re-model the agent (strip `route.model` for agent loops, drop the dead per-step model path, align the tool description); ReDoS caps on config patterns (length ≤ 200, test ≤ 4 KB); one log per session in every `.catch` + log the silent config drops; phase key charset `^[a-z][a-z0-9_-]{0,31}$`; `additionalProperties: false` on the tool schema + `typeof e.skill`; post-`next` bookkeeping in try/catch; config file size cap 64 KB. Deferred by design: effort ceiling for model-declared routes; window check beyond haiku.
