 - **Amendment (2026-10-11, wave 3-B, commit 604a6c4)**: clause (2) superseded: the dialog carries CONTEXT (skill description = first sentence of its SKILL.md frontmatter, five YAML forms, hardened read: name allowlist, stat kind file, size cap, `clean()` Cc/Cf + code points; agent description from `agent.offer`, bounded cache; phase `about` line, new 120-char field on the 11 routing.json phases, kept in memory not on Route) and the REAL next model id + effort. Options Later / Keep / Change (T3 Later / Keep). Change = model (4 fixed alias labels with tier role) → effort among those the phases headed by that alias offer (ascending, ≤ 4, one → skipped, zero → Later) → scope; the pair maps to an existing PHASE (rows stay phase names; row's current phase wins a tie; same phase = Keep); a pair no phase offers = a new phase by hand. Other anywhere = Later + toast (no echo). A main-row change toasts the real decision + `/route switch on` hint on a held downgrade. Three lenses rejected inline-route rows and dialog phase edits (2 BLOCKERs). First real use: user moved security-auditor to `judge` (opus/xhigh) through it; floor aligned (`model: opus`, 2026-10-11). Links [[EVAL-044]].
+- **Amendment (2026-10-11, wave 3-C, commit cd8d72f)**: clause (6) extended: `/route forget <name|all|projects>` (composer only) clears decisions in the tracked file through the same writer: a name in every table (`confirmed`, `changed` → row restored to its recorded `from` when it is a string, the row still equals `to` and `from` is a known phase; `projects[*]` pruned), asked again at once; `all`/`projects` confirm through the engine dialog (Cancel first, anything else = cancelled) and hold the single-dialog slot; nothing written when nothing to forget; the answer names a restored row's file + values to realign (a floor aligned to the decision makes the census FAIL after the restore). No per-user decisions file (user: "seulement le forget"): another user inherits the shared memory and may forget. Residuals (security LOW/MEDIUM): raw error text in the answer, file fragments unsanitized in the answer, `floorFile` name not allowlisted, `__proto__` plan/apply mismatch, `changed.phases` restorable.

 ## 2026-10-11
 - model-router W3-A (first-use confirmation) landed 22455c0 on feature/model-router-confirm. User asked for it after the W2 merge; 3 pass-B answers. Plan r1→r4: correctness BLOCKER (Everywhere decision = census red → `changed` WARN exemption), robustness (first challenger killed by DNS, fresh one: project-tree layer dropped for security, single dialog in flight, keep-previous after first load), confirmation CONCERNS(6). Feater DONE (169 tests) + 4 rounds. Verifier ECARTS(3)/(2)/CONFORME; security BLOCK(1) REAL: password with `@`/`/` landed in the tracked key → strict parsing, no `local:` keys, output cap → re-verify ECARTS(1) fixtures → PASS. The working-tree mod was hot-loaded by the engine: my own dispatches opened T2 dialogs the user answered (verifier Keep, feater Keep, security-auditor → implement → user reset to verify); first misread as a test leak (LRN-212). GATE 0 oracle as heredoc not runnable → script. Full make test green (env red only). Docs P1-P13 user-approved (patch in flight); BDR-116, LRN-212, EVAL-043 written. Next: doc commit, memory commit, user merge + publish by hand; T1/T3 live checks open.
 - model-router W3-B (dialog with context) landed 604a6c4 + data 32b71d2 + floor chore. User asked after W3-A: explain what is decided, OK/change/later, model then effort then scope. Plan r1→r3: all three lenses killed my inline-row format and the T3 phase edit (2 BLOCKERs avoided); efforts derived from the phases of the chosen model. Feater DONE first pass (229 tests), verifier ECARTS(2)→(1)→CONFORME, security PASS. GATE 0 heredoc CHECK not runnable again → script. Live during the gates: user answered the NEW dialog for security-auditor → opus/xhigh (the request's example; kept, floor aligned to opus, model-routing lock updated), plan-challenger → verify (reset on user go), orchestrate Keep (T3 check done). My `changed = {}` reset wiped a legit entry → census red for one commit → restored. Docs P1-P6 approved (patch in flight), BDR-116 amendment + EVAL-044 written. Next: doc commit, memory commit, user merge of feature/model-router-confirm (W3-A + W3-B) + publish by hand; T1 live check still open.
+- model-router W3-C `/route forget` landed cd8d72f (+ data commit: escalate Keep). User asked whether decisions can be cleared and what another user can do; chose the command only, no per-user file. Plan r1→r3: three lenses CONCERNS (false `st.mem` premise, kind order, docs scope, census red after restoring an aligned floor, no confirmation on `all`), confirmation CONCERNS(3). Feater DONE; verifier ECARTS(2) with a REAL typo (`ForgetPlan`), then coverage only ×2 → cap → user accepted; security PASS (1 MEDIUM + 4 LOW parked). My own `route(escalate)` call opened the T3 dialog the user Kept. Branch feature/model-router-confirm now carries W3-A/B/C (14 commits), unmerged, unpushed; merge on signal; full make test running.
