docs(fase2): /trekbrief — gated MVP vertical-slice brief (6/6) [skip-docs]

Fase 2 started. Brief for the MVP vertical slice (one synthetic project
end-to-end on MAF 1.9.0: debate -> blocking validator -> two-layer HITL +
provenance -> ExpeL learning) produced via /trekbrief from documented intent
(incremental-plan §Fase 2 + capability-map §1/§5 + Fase 1 findings), not live
Q&A per the project operating model. framing=preserve; phase_signals=high/opus.

Brief-reviewer gate passed 6/6 (all dimensions 5; verdict PROCEED_WITH_RISKS)
after 2 iterations: iter 1 flagged a no-op token-accounting criterion and a
false-positive on research-field order; 3 derivable refinements applied
(retargeted the UsageDetails assertion, added Open Questions for the concrete
local model + Foundry deployment names, added a topic-count note). Validator
green (0 errors/warnings).

3 research topics identified (gaps the capability-map did not resolve): native
HITL in MAF workflows, local_folder via MCPStdioTool + citation provenance, and
a real local-profile chat client (spikes used only FakeChatClient). Manual path:
stopped at the brief as a gated checkpoint; research must run before /trekplan.

.gitignore: ignore generated .html annotation + progress.json render-derivatives
under .claude/projects/ (the .md sources stay tracked).
