Operator reviewed the brief (S57) and approved as-is, then chose research-first
at the /trekplan research gate (option A: investigate only the genuinely-external
topic 1; fold local topics 2/3 into /trekplan exploration).
Topic 1 finding (validator-green; claude-code-guide + CC 2.1.196 binary + a real
local /deep-research run, all cited): /deep-research is a built-in *dynamic
workflow* (not a skill), outside the Skill-tool allowlist. Trigging is
prose-instruction only; the report lands inline in context with no on-disk
artifact (only the .js script is written). => the engine must be instruction-based
+ in-context transform, surface-only. Brief's v2.1.154+ / Pro-via-/config
constraints verified correct; SC3 ("dynamic workflows off -> fallback to swarm")
is correct as written (an earlier review note that called it a conflation rested
on a wrong premise and is retracted).
- docs/deep-research-engine-research.md: new, research-validator green strict.
- docs/deep-research-engine-brief.md: status draft->ready (operator-approved),
research_status pending->complete (option-A decision recorded), Research Plan
traceability note.

Operator-delivered draft (S55) carried only brief_version/status/brief_quality/
research_topics and an explicit "reconcile frontmatter against brief-validator
before /trekplan" note. Add the required fields (type, task, slug,
research_status, phase_signals_partial) plus the brief_version 2.2 gates:
framing: refine (operator-confirmed — additive opt-in engine, swarm stays
default, no contract change) and a 5-line ## TL;DR. brief-validator passes
strict + --min-version 2.2. status stays draft pending operator review before
the /trekplan run.

Records the operator-supplied brief for an --engine {swarm|deep-research}
choice on /trekresearch's external phase (swarm stays default; deep-research
delegates the external phase to the built-in workflow with auto-fallback).
Backlog item only — not implemented. Lives beside the work (docs/), tracked.
