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.
