/discovery - Dense Discovery Phase Adapter

Absorbed skills (ag-s43tg)

brainstorm (goal-vs-implementation clarification) + design (product-fit pressure test) — trigger detail in the Folded-In section below.

YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.

Constraints

• Delegate research and plan separately; delegate premortem only for MVP-slice mode because the fanout duel is already its premortem verdict.
• Prove a capability is absent before scoping new construction to prevent duplicate machinery and false net-new estimates.
• Route only fanout/one-way-door decisions through the duel; keep routine MVP slices inside the bounded quick path.
• After three MVP premortem failures, run exactly one bounded plan-pawl helper round; resume on UNSTUCK and ask the human only on ESCALATE.

Loop position: move 1 (shape intent as BDD) plus the seed for move 3 (slice candidates) of the operating loop. Discovery turns a goal plus delegated child artifacts into one dense execution packet for /crank and /validate. It is also the re-plan engine for /rpi's Agile Re-Plan Loop: after the initial plan, it runs only from an explicit orchestrator re-plan request carrying a cited Learn plan-impact packet. Seed slice candidates small: one Given/When/Then behavior each, refactor candidates kept separate from feature candidates — small batches + refactor-after-green are the load-bearing quality moves, not test-first ordering (Finster 2026, skills/standards/references/agentic-workflow-evidence.md); binding decomposition discipline is /plan (PR-010/PR-011).
