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.

Phase 2 (Season 1 Vertical Slice — Soil) discuss-phase output. 02-CONTEXT.md
captures 34 implementation decisions across 8 gray areas (garden geometry &
input · time density · Lura's arc · letter composition · Begin screen ·
Memory Journal · plant placeholders · Phase-2 Settings UI scope). Locks the
4×4 grid + click+inline seed picker, 2–5min growth band per plant with
auto-harvest-while-offline, 3 Lura gate visits gated by 1st/4th/8th harvest,
authored Ink letter skeleton with templated slots, full-screen letter on
≥5min absence, tasteful placeholder Begin screen (Phase 3 paints), full-
screen Journal modal revealing after first harvest, simple Phaser-primitive
plants with subtle ready-state pulse, save-management-only Settings.
Phase 2's first commits: BigQty wrapper, Zustand 5 store, tick scheduler.
Save schema is a v1 *extension*, not v1→v2.
02-DISCUSSION-LOG.md preserves the alternatives considered for human review.
