chore(model-routing): wave-4 census + docs + BDR-066 (client-handover doc-gen → sonnet)

 - **Caveat (execution)**: /feat re-arch broke 5 stale assertions in lib/tests/loops-light.test.sh (locked OLD feater architecture) — repointed to skills/feat/SKILL.md (FSK, mirrors HOT/HSK split) + new dispatch lock + 1-line reflow in feat SKILL for single-line grep lock (LRN-093 class).
 - **Wave 2 (2026-07-15, user directive)**: wave-1 exclusion list left execution running on the big session model = the waste this split kills. REVERSES the "split hotfix rejected" alternative above (reason held for bugfix — investigation interleaved w/ fix — but NOT hotfix: LOCATE→apply is linear/separable). Changes: /hotfix split like /feat (LOCATE reflection inline + MODEL GATE, hotfixer sonnet EXECUTOR — rewritten dual-use: also the seo/geo/web-validate L1 applier; revert-not-loop preserved) → hotfix JOINS gated group, census 12→13. /commit-change dispatches sonnet commit-changer (propose→dispatcher gates→apply; grouping ON sonnet so NO model gate; AskUserQuestion dropped from agent). /release-candidate dispatches new sonnet release-executor (2 spans prep/finish; when-to-release + push + version-number decision STAY in dispatcher). /doc → doc-syncer (sonnet) dispatch; /status → status-reporter (kept HAIKU — right tier for read-only collection; win = off big model, not the tier). Gate exclusion list now = commit-change/doc/status/release-candidate. Consumer-staleness swept (LRN-113): feat Rule 1 DOWNGRADE + feat commit-split both repointed off the bare executor agents to the /hotfix + /commit-change skills.
 - **Wave 3 (2026-07-15/16, user directive)**: split the last two inline execution-carrying agents like /feat. /bugfix: investigation+diagnosis+contract inline behind the gate; bugfixer = sonnet EXECUTOR (fix + regression test from a closed FIX PLAN; no Agent/AskUserQuestion; BUGFIX-EXEC REPORT). verify+secure loop stays in main loop, executor = its re-dispatched dev (verify-secure-loop.md intro now: BOTH consumers dispatched, no inline branch). FINISHES reversing the "split bugfix rejected" carve-out (hotfix went wave 2, bugfix now) — investigation↔fix coupling accepted, mitigated by structured DIAGNOSIS + verify loop. /code-clean: PHASE-1 audit + validation gate inline (reflection); code-cleaner = sonnet PHASE-2 EXECUTOR (delete approved dead code, inline-load refactorer, re-audit) — refactor NOW on sonnet (inline-load pin was inert on big model). exported-symbol per-item consent stays AT THE GATE. Consumer-staleness swept: hotfix deeper-bug escalation → /bugfix skill (not bare agent); onboard STEP 6 + tour Phase B read-only-audit → general-purpose/analyzer (big model, NEVER the sonnet executor — audit stays big). Both skills STAY gated. Also: Explore built-in kept inheriting session (search feeds reflection = big deserved; custom sonnet override created then reverted — built-in already inherits + no owned prompt). census 36→42, loops-light repointed 35/0.

+- **Wave 4 (2026-07-16)**: client-handover doc-gen → sonnet, REDACTION-ONLY (user flipped from whole-writer after the full read). Key finding: nested audits (/seo,/harden,/web-validate — gated wave 1) must run BIG either way → whole-writer = ~7 extra gate-yields + resumable state machine on a CLIENT deliverable for ~0 extra sonnet work. Design: client-handover-writer TRIMMED to ship pipeline (STEP 1-8, all interactive gates native on big, nested audits inherit big) + doc-gen orchestration (resolve questions/NAP/precheck/overwrite/client-name inline → PACKAGE) → dispatches NEW sonnet handover-doc-writer (STEP 9-16: reads memory+git, synthesizes 6-chapter doc, word-count/skill-leak/anchor gates, renders HTML+PDF; GATE-FREE, no AskUserQuestion/Agent). client-handover JOINS gated group (orchestrates audits = reflection); its opus pin dropped (inherits big via inline-load). census 42→46. Branch feature/client-handover-dispatch (off develop, waves 1-3 merged first).

NOTE: a Task-20 implementer ran `git checkout -- settings.json`, discarding user /model=opus working-tree state (LRN-098) — flagged to user (re-run /model). Lesson worth an LRN: constrain SDD implementers from git ops on files outside their task.
