Balance-backlog S32 (CODE+AUDIT). Audited whether the brief interview and the
research / exploration / reviewer swarms ride NATIVE Claude Code primitives or
hand-roll their own engine. Finding: all five ALREADY delegate natively — no
re-implementation, so no command-file change. Documented the principle + a
standing regression guard instead.
- V01 (trekbrief Phase 3): Q&A turn-taking is `AskUserQuestion` (line 144 / step
4); the "selection rule" is section-selection POLICY, not a hand-rolled menu.
- V07 (research interview): `AskUserQuestion`, one-at-a-time.
- V08/V11/V24 (research / exploration / reviewer swarms): parallel `Agent`
fan-out in a single message ("in parallel … single message" / "via the Agent
tool — one message, multiple tool calls"). Policy layers (dimensions/schemas/
triangulation, typed roles/effort/scaling, 12-key rule catalogue/no-cross-feed/
dedup) cleanly separated from the engine.
- docs/architecture.md: new cross-cutting principle note "delegate the engine,
keep the policy" recording the native primitives, the per-command policy, and
the audit verdict.
- tests/lib/doc-consistency.test.mjs: +3 S32 pins (architecture note present;
each swarm command lists Agent + mandates single-message parallel spawn;
trekbrief Phase 3 delegates to AskUserQuestion). Guards engine creep-back.
No command-file edits (all native). No model/frontmatter change (D3 firm). No
Handover-1 change. Non-breaking. Tests 734 (732 pass / 2 skip / 0 fail), bar
`node --test`; `claude plugin validate` green (1 accepted warning).
