5-plan MVP slice proposal across 3 waves: Wave 0 lands the three
deferred foundations (BigQty wrapper around break_eternity.js, Zustand
5 store wiring, tick scheduler / monotonic clock). Wave 1 ships two
parallel vertical slices (Begin+Plant+Grow, Harvest+Journal+Fragments).
Wave 2 ships the Lura gate-visit slice and the offline-letter slice
including Playwright PIPE-07 e2e. All 24 REQ-IDs addressed in the
coverage map; 10 architectural patterns enumerated; tick rate locked at
5Hz with 24h offline cap; AudioContext.resume() bootstrap pattern
documented for first-run + returning-player paths; V1Payload extension
shape locked per CONTEXT D-34 (no migrate_v1_to_v2 added). 10
assumptions logged, 8 are LOW risk; 2 are MEDIUM (canvas-DOM coord
mapping under FIT scale, inklecate Windows binary invocation) and
flagged for early verification in Plans 02-02 and 02-04.
