feat(agents): W2/S2 doc pipeline two-mode + last inline conversions (BDR-077)

doc-syncer: ONE agent, TWO dispatch modes around the dispatcher's gate —
MODE: audit (model="opus" call-site override, READ-ONLY, drafts + PATCH
PLAN) / MODE: patch (sonnet pin, applies the APPROVED plan, shape oracle
w/ revert-on-fail, emits CHANGE SUMMARY + PATCHED_FILES). Deviation from
plan's 2-file split, per the challenge's own commit-changer mode
precedent: zero text duplication, zero lock moves. Fixes a LATENT DEFECT:
/doc dispatched an agent whose STEP 8 gate could never fire (dispatched
agents cannot ask) — the gate now lives in the dispatcher (DISPATCHER
PROTOCOL section). doc-commit.md consumes the patcher's CHANGE SUMMARY
(the in-thread context now crosses the dispatch boundary, LRN-126).
Consumers rewired: /doc (audit→gate→patch→commit), onboard (audit
report-only, opus), doc-commit steps in bugfix/hotfix/feat/ship-feature/
init-project(5b+10c); scaffolder loses PHASE 6 (README = init 5b's job);
scaffolder + onboarder now DISPATCHED in init-project/onboard (pins live,
was inline on session model). In-wave planted-drift smoke PASSED
end-to-end, disk-verified (audit caught npm-run-dev drift → [MINOR] plan
→ patch applied → summary crossed). Census §14-15 (103 pass), make test
exit 0. Typed plugin-probe dispatch resolution verified post-restart.

 ## STEP 6 — DOC SYNC (automatic)
 
-Load `$HOME/.claude/agents/doc-syncer.md`.
-Execute in automatic mode:
-`auto-mode scope: <list of files modified during this session>`
+Dispatch the doc pipeline (BDR-077 — audit judgment on opus, patch on the
+sonnet pin, gate HERE):
+1. `Agent(subagent_type="doc-syncer", model="opus")` — `MODE: audit` +
+   `auto-mode scope: <list of files modified during this session>`.
+2. Silence (NONE) → done. `[MINOR]` PATCH PLAN → re-dispatch
+   `Agent(subagent_type="doc-syncer")` with `MODE: patch` + the plan
+   verbatim (no gate — auto behavior preserved; a `SHAPE ESCALATION` in
+   its report comes back here, gated as SIGNIFICANT).
+3. SIGNIFICANT → gate here (`Apply? yes / no / select`), then
+   `MODE: patch` with the approved subset.
 
 **Then commit the docs** — follow `$HOME/.claude/lib/doc-commit.md`: it surgically commits
 ONLY the files doc-syncer patched (its `PATCHED_FILES` output), never `git add -A`, never
