/discovery - Dense Discovery Phase Adapter

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

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 /validation.

Strict Delegation Contract (default)

Discovery delegates to /brainstorm (conditional), /design (conditional), /research, /plan, and /pre-mortem via declared skill invocations. Strict delegation is the default.

Anti-pattern to reject: inlining /research work (grep + read + synthesize), collapsing /plan into an inline decomposition, skipping /pre-mortem. See ../shared/references/strict-delegation-contract.md for the full contract and supported compression escapes (--quick, --skip-brainstorm, --interactive/--auto, --no-scaffold).

See docs/learnings/orchestrator-compression-anti-pattern.md for the live compression signature. See references/isolation-contract.md for the mechanical four-lever model and the compression patterns flagged by scripts/check-skill-isolation.sh. See references/best-practices.md for the lifecycle principle + anti-pattern citation table.
