Fase 3 brief: sequential fan-out orchestrator over N portfolio projects,
reusing the single-project run_project seam. Four operator design decisions
locked via interview: isolate execution-state per project but SHARE one
VerdictStore (ExpeL accumulates across the portfolio); sequential (concurrency
= documented extension point); fixed config-list topology (resolves plan §12
open decision); list-of-RunResult + thin aggregate output. 0 research topics
(all internal; MAF concurrency already spiked in Fase 1 + de-scoped).
brief-reviewer (opus) → PROCEED on first iteration, all 6 dimensions pass
(completeness 5, consistency 4, testability 4, scope 5, research 5, memory 5).
Folded in its PROCEED-level refinements before finalize: per-project docs_dir
MUST be config-driven or SC1 breaks; SC7 given a concrete parametrised-test
assertion; SC5 baseline made relative (current+new, not a guessed 103); SC3
detach encodable as an automatic guard; SC4 fixture must yield overlapping
features; new synthetic project flagged AI-authored (user-not-domain-expert).
Validator: valid, 0 warnings. phase_signals: plan/execute/review = high/opus.
