Total 17 authored. Warm pool depth ≥9 satisfies the worst-case all-rosemary playthrough at the 8th-harvest Lura threshold (CONTEXT D-14). content/dialogue/season1/compost-acknowledgements.ink — authored content (6 short lines in the gardener-keeper voice) shipped ahead of Plan 02-04's Ink runtime; Garden.ts compost branch carries a TODO marking the Plan 02-04 wiring point Garden.ts harvest+compost pointer wiring — handleTilePointerDown branches on tile state (empty → SeedPicker / ready → harvest / immature → compost); update() loop detects newly-appended harvestedFragmentIds and sets fragmentRevealId for the D-25 reveal flow; SimContext built once at create() from filtered eager `fragments` corpus PIPE-02 structural verification — scripts/check-bundle-split.mjs (refactored as exportable `runCheck()` for Vitest cover; CLI invocation guard wraps process.exit) + scripts/check-bundle-split.test.mjs (3 cases file exists / parses without exit / runCheck returns documented shape) + ci chain extended to run check:bundle-split AFTER build	02-04-lura-gate-beats (Lura's Ink runtime swaps in for the compost-acknowledgements TODO + Lura beats consume harvestedFragmentIds.length thresholds) 02-05-letter-settings-e2e (offline auto-harvest writes to harvestedFragmentIds; e2e exercises the full Begin → Plant → Grow → Harvest loop end-to-end)	added patterns sim/memory module shape: pool.ts (filter helper) + selector.ts (deterministic PRNG-driven choice + sentinel fallback) + index.ts (barrel). Repeats the sim/<subsystem>/ shape established by sim/garden in Plan 02-02. Deterministic selector via mulberry32 PRNG seeded from `(harvestedFragmentIds.length, plantedAtTick)` — both sim-internal counters; no Date.now leaks into selection. Pinned by 16 selector tests including determinism, gating, no-dup, season exclusion, sentinel exclusion from normal pool. Pitfall 10 mitigation: plant-type unlock thresholds checked AFTER the harvest commit (computePlantUnlocks uses harvestedIds.length, not the pre-commit count). Pinned by 3 boundary tests — locked at 2/5 harvests, unlocked at 3/6. Pitfall 8 (gated-pool exhaustion) — chosen behavior is the sentinel fallback. EXHAUSTION_FALLBACK_ID = 'season1.soil._exhaustion' is authored content tagged ['_meta']; the pool filter excludes _meta-tagged fragments, and selector.ts looks the sentinel up explicitly when filterPool returns []. Plan ships sufficient warm-pool depth that the sentinel is unreachable in normal Phase-2 play; it remains a defensive structural fallback. FragmentSchema extension via optional `tags` — back-compat with Phase-1 demo fragments that don't carry tags (loader.test.ts continues to pass against a tag-less fixture). Phase 2+ authored fragments ship tags for tonal-register gating. DOM-rendered journal tier: Journal + FragmentRevealModal + JournalIcon all use selectable text (`userSelect: 'text'`) with `<pre>` for body rendering. MEMR-05 mechanically verified — canvas rendering would foreclose copy-paste from day one. Application-layer SimContext injection — Garden scene loads the eager `fragments` corpus at create() and threads it through every simulateOneTick call. Sim modules NEVER import import.meta.glob; the corpus is a pure data input. Journal-icon owns local `open` state (not the store) — V1Payload has no journal-open flag by design; the affordance owns its own visibility lifecycle without polluting the persisted save shape. PIPE-02 structural verifier as an exportable `runCheck()` returning a structured result, with the CLI invocation guarded behind an import.meta.url comparison so Vitest can import without process.exit firing. Pattern reusable for Phase 8 visual-regression scripts.	created modified removed src/sim/memory/pool.ts (filterPool — pure Season + plant-type tonal-register + no-dup gating) src/sim/memory/selector.ts (selectFragment + EXHAUSTION_FALLBACK_ID + mulberry32 PRNG) src/sim/memory/selector.test.ts (16 tests — gating / no-dup / determinism / sentinel fallback / sentinel pool exclusion / season exclusion) src/sim/memory/index.ts (barrel) src/ui/journal/Journal.tsx (D-24 full-screen Memory Journal modal) src/ui/journal/Journal.test.tsx (7 tests — empty state / fragment body render / userSelect text / Season grouping / close callback / aria-label / unresolvable id silent skip) src/ui/journal/FragmentRevealModal.tsx (D-25 active-play reveal modal) src/ui/journal/FragmentRevealModal.test.tsx (6 tests — null when revealId is null / body rendered / backdrop dismiss / article-body stopPropagation / inner Close dismiss / unresolvable id silent dismiss) src/ui/journal/journal-icon.tsx (D-23 reveal-after-first-harvest gate + corner affordance) src/ui/journal/journal-icon.test.tsx (3 tests — null pre-first-harvest / icon renders post-first-harvest / click opens journal modal) src/ui/journal/index.ts (barrel) content/seasons/01-soil/fragments/lura-first-letter.md (long-form Markdown fragment, warm tonal register) content/seasons/01-soil/fragments/winter-rose-night.md (long-form Markdown fragment, heavy tonal register) content/dialogue/season1/compost-acknowledgements.ink (6 short authored compost beat lines; Plan 02-04 wires the runtime) scripts/check-bundle-split.mjs (PIPE-02 structural verifier with exportable runCheck()) scripts/check-bundle-split.test.mjs (3 Vitest cases — exists / parses-without-exit / structured result) src/content/schemas/fragment.ts (added optional `tags` field; back-compat preserved) src/sim/garden/commands.ts (harvest + compost branches; SimContext interface; PLANT_UNLOCK_THRESHOLDS table; Pitfall 10 mitigation; selectFragment integration; BLOCKER 3 invariant preserved) src/sim/garden/commands.test.ts (added 18 new cases — harvest / compost / Pitfall 10 boundaries / sentinel fallback / immutability + simulateOneTick integration; updated the previously-stubbed "harvest/compost ignored" case) src/sim/garden/index.ts (export harvest/compost/SimContext) src/sim/index.ts (re-export ./memory) content/seasons/01-soil/fragments.yaml (replaced single placeholder with 14 authored fragments + sentinel; bible voice maintained throughout) src/ui/index.ts (re-export ./journal) src/App.tsx (mount FragmentRevealModal + JournalIcon) src/game/scenes/Garden.ts (build SimContext at create() from eager `fragments`; handleTilePointerDown branches harvest/compost on stage; update() detects new harvest and triggers D-25 reveal flow) package.json (new check:bundle-split script; ci chain extended)	Pool exhaustion behavior chosen: sentinel fallback (EXHAUSTION_FALLBACK_ID = 'season1.soil._exhaustion'). The alternative — repeat-most-recent — was rejected because (a) it makes the fragment ID corpus mutable in spirit (a fragment id can re-appear in harvestedFragmentIds, breaking the no-dup invariant downstream consumers expect) and (b) the bible voice naturally accommodates a single sentinel about steady-part-that-doesn't-need-re-learning. The authored warm pool ≥9 satisfies the worst-case all-rosemary 8th-harvest Lura threshold so the sentinel is structurally unreachable in normal Phase-2 play. Plant-type unlock thresholds finalized within Plan author's discretion (CONTEXT D-05): rosemary @ 0, yarrow @ 3, winter-rose @ 6. The 3/6 spacing matches the 1/4/8 Lura beat cadence (D-14) — the player feels yarrow unlock right around the time Lura's mid-beat fires (4th harvest), and winter-rose unlock arrives shortly before the farewell beat (8th harvest). Adjustable in playtest by ±1 — the model (tied to harvest count) is locked. Garden scene loads fragments via the EAGER `fragments` export filtered to Season 1 — NOT via `await loadSeasonFragments(1)`. Trade-off documented: Phase 2 has only Season 1, so the eager path is simpler and avoids an async-init dance in Phaser create(). The lazy plumbing is structurally proven by check-bundle-split.mjs; Phase 4+ should swap to lazy when Season transitions land. INEFFECTIVE_DYNAMIC_IMPORT warnings in `npm run build` are inherited from Plan 02-02 and will resolve naturally when consumers move to lazy-only. Compost beat — Plan 02-03 ships the AUTHORED CONTENT (compost-acknowledgements.ink, 6 lines in the gardener-keeper voice) but does NOT yet render it. Plan 02-04 owns the inkjs runtime; Garden.ts has a TODO at the wiring point. This split lets the writer iterate on voice independently of the runtime work. Journal-icon's 'j' hotkey (CONTEXT D-29) is intentionally NOT wired in Plan 02-03 — keyboard-shortcut surface lands with the wider Settings hotkey work in Plan 02-05. The plan's task-2 step-3 sketched a window-CustomEvent indirection; the simpler choice is to defer the keybinding until Plan 02-05 owns the surface holistically. FragmentRevealModal silent-dismiss on unresolvable id (defensive). The state-update-during-render is bounded — the next render reads fragmentRevealId === null and exits at the guard. React does not warn for this single-step path because the setState transitions to a steady state in O(1) re-renders. Knuth's multiplicative hash on `(harvestCount * 2654435761 + plantedAtTick) | 0` for the seedHash. Spreads adjacent (count, tick) pairs across the 32-bit seed space so mulberry32 produces visibly-different results on adjacent harvests; the `| 0` truncates to 32-bit signed int (mulberry32 internally re-coerces to unsigned). Sentinel exclusion from the normal pool is enforced in BOTH the schema-tag check (`if (f.tags.includes('_meta')) return false`) AND by selector.ts NEVER exposing the sentinel via the seeded-pool branch. Dual defense — accidental tag drift on a future fragment can't smuggle the sentinel into normal play.	Deterministic-selector pattern (selectFragment): pure inputs (corpus, season, plant type, harvested ids, seed hash) → Fragment | null with sentinel fallback. Reusable for Phase 5+ memory-vignette selection (place-memory + Loom feeds), Phase 4+ cross-pollination output, anywhere a 'pick one from a gated pool, deterministically' is needed. Application-layer-injected SimContext: sim modules take pure data; the application layer (Phaser scene) loads the data and threads it through. Plan 02-04 will extend SimContext with `inkStory` for Lura beat firing; Plan 02-05 will extend with `offlineEvents` for the letter-from-the-garden composition. DOM-overlay-over-canvas pattern (Plan 02-02 establishment continues): Journal + FragmentRevealModal + JournalIcon are React DOM siblings of PhaserGame. MEMR-05 selectable text demands DOM, not canvas. The pattern repeats for Plan 02-04 Lura dialogue and Plan 02-05 Letter overlay. FragmentSchema optional-field extension: Phase 2 added `tags?` without bumping schemaVersion. The same path is open for Phase 4+ (e.g., `unlocks?: string[]` for cross-pollination). Migration only required when an existing field's shape changes, never for additive optional fields. PIPE-02 structural verifier as Vitest-importable Node ESM: `runCheck()` exported, CLI gated by import.meta.url. Pattern reusable for Phase 4 Season-2 onboarding (extend the script's known-content list) and Phase 8 visual-regression baselines (different filename heuristics, same export shape). Journal-icon owns local open state (not the store): UI affordances that don't need to persist across sessions live in component state. V1Payload stays clean — only canonical game state crosses the save boundary.	GARD-03 GARD-04 MEMR-01 MEMR-02 MEMR-03 MEMR-04 MEMR-05 MEMR-06 PIPE-02 UX-01	12min	2026-05-09

Phase 2 Plan 03: Harvest, Memory Journal & Fragments Vertical Slice Summary

One-liner

The second half of the Season-1 active-play loop — sim/memory module with deterministic mulberry32-seeded selector + sentinel fallback for the gated-pool exhaustion case (Pitfall 8); harvest + compost pure commands extending sim/garden with Pitfall 10 mitigation (yarrow @ 3 / winter-rose @ 6 unlocks computed AFTER harvest commit); 17 authored Season-1 fragments under /content/seasons/01-soil/ in the bible voice (9 warm / 3 contemplative / 2 heavy / 1 _meta sentinel + 2 long-form Markdown); DOM-rendered Memory Journal + active-play FragmentRevealModal + first-harvest-gated JournalIcon all selectable + copy-pasteable per MEMR-05; Garden scene wiring harvest/compost pointer events through to the D-25 reveal flow; PIPE-02 structural verifier (scripts/check-bundle-split.mjs) as a Vitest-importable Node ESM module integrated into npm run ci.

Performance

• Duration: ~12 min (sequential executor; lighter than 02-02's 18min — Plan 02-03's surface is sim/memory + journal UI tier without a new render layer; the architectural firewall edges shipped in 02-02 carry over directly)
• Started: 2026-05-09T13:55:00Z (approximate; orchestrator-recorded plan-start time)
• Completed: 2026-05-09T14:08:00Z

Accomplishments

• Active-play loop closed end-to-end on real authored content. A player can plant a seed (Plan 02-02) → watch it grow → click a ready plant → harvest fires through the sim, picks one fragment deterministically from the gated pool → reveal modal pops with the fragment's full text → close → fragment files into the Memory Journal under Season 1 → journal icon (invisible until first harvest) appears in the corner → click opens the full-screen modal listing all collected fragments grouped by Season.
• 17 Season-1 fragments authored in voice, satisfying the worst-case-all-rosemary depth at the 8th-harvest Lura threshold (CONTEXT D-14) without reaching the exhaustion sentinel. Bible voice maintained throughout — warm, specific, intermittent, sometimes funny, sometimes devastating; the gardener-keeper voice (NOT Lura — she's the warmth anchor; the contrast lives here).
• MEMR-06 deterministic selector landed: same inputs ALWAYS yield the same fragment. Pinned by 16 Vitest cases including determinism, Season + plant-type gating, no-dup, sentinel exclusion from the normal pool, and Pitfall 8 exhaustion fallback.
• Pitfall 10 boundary mechanically pinned: yarrow locked at 2 harvests, unlocked at 3; winter-rose locked at 5, unlocked at 6. Three explicit boundary tests in commands.test.ts.
• PIPE-02 structurally verified: scripts/check-bundle-split.mjs exits 0 after npm run build; integrated into the CI chain so any future change that breaks the lazy-content plumbing fails the build.
• No raw Decimal outside src/sim/numbers/. No hardcoded player-visible strings outside /content/. Zero new ESLint sim-purity violations. All sim modules pure (no Date.now / setInterval / DOM / fetch).

Per-tag Distribution

Tag	Count	Notes
warm	9	rosemary pool. Worst-case 8th-harvest depth + 1 buffer
contemplative	3	yarrow pool. Yarrow unlocks @ harvest 3
heavy	2	winter-rose pool. Winter-rose unlocks @ harvest 6
(Markdown warm)	1	lura-first-letter.md
(Markdown heavy)	1	winter-rose-night.md
_meta	1	season1.soil._exhaustion sentinel
Total	17

The yarrow + winter-rose pool sizes (3 + 2 = 5 contemplative-or-heavy entries plus the 2 long-form Markdown carrying tonal weight) reflect that those plants unlock progressively into the playthrough — the player has fewer harvests left to draw from those pools, and an over-deep contemplative pool is wasted. If a playtest shows the contemplative or heavy pool feeling thin, the writer can add more without changing any code (the pool is purely data; the selector consumes whatever's authored).

Plant-type Unlock Thresholds (CONTEXT D-05, finalized)

Plant	Unlocks at harvest #	Notes
rosemary	0 (start)	Available from first plant. Warm pool.
yarrow	3	Spaced before Lura's mid-beat (4th harvest, D-14) so the player feels the unlock just before the conversation.
winter-rose	6	Spaced before Lura's farewell beat (8th harvest, D-14) so the heavy plant arrives in tonal alignment with the arc's turn.

These are tunable in playtest within ±1; the model (harvest-count thresholds, not wall-time gates) is locked per the STRY-10 contract.

Pool Exhaustion Behavior (RESEARCH Pitfall 8)

Chosen behavior: sentinel fallback. When filterPool() returns an empty array, selectFragment() looks up the fragment with id season1.soil._exhaustion (authored in fragments.yaml, tagged ['_meta']) and returns it. If even the sentinel is missing (degenerate test fixture), the selector returns null and harvest() returns the original state reference unchanged (the player's tap was a no-op — the safest possible behavior since refusing to harvest preserves the ready plant).

Documented in:

• src/sim/memory/selector.ts (docblock).
• content/seasons/01-soil/fragments.yaml (the sentinel entry's comment block).
• src/sim/memory/selector.test.ts covers (a) sentinel-returned-when-pool-empty, (b) null-returned-when-sentinel-missing, (c) sentinel-NEVER-returned-via-normal-pool.

Why sentinel over repeat-most-recent: the no-dup invariant on harvestedFragmentIds is load-bearing for downstream consumers (Journal de-dup, Plan 02-05's letter slot vocabulary, Plan 02-04's Lura beat counters that depend on count). A repeat-most-recent path would silently re-grow harvestedFragmentIds past the corpus size, polluting these consumers. The sentinel fragment is a real id appended exactly once on first exhaustion (and never again — it itself is in the no-dup set after).

scripts/check-bundle-split.mjs Heuristic — first-try assessment

First-try result: the structural assertion passes via chunkContentMatch=true. Phase 2 is currently in eager-corpus mode (the fragments export inlines all Season-1 yaml + Markdown into the main bundle as ?raw strings), so the chunk content match fires on the source-path /content/seasons/01-soil/ and on the literal fragment id season1.soil.first-bloom.

chunkNameMatch=false is the expected state for Phase 2 — Vite does not emit a separate Season-1 chunk while the eager path keeps the same source modules in the main bundle (build emits [INEFFECTIVE_DYNAMIC_IMPORT] warnings noting this). When Plan 02-04+ switches consumers to lazy-only, chunkNameMatch will start firing and the warnings will resolve.

No tuning was needed. The OR-of-three structural checks gives the verifier room to evolve as Phase 4+ Season-2 onboarding lands without forcing the heuristic to be tight on Day 1.

Garden Scene Fragment-Loading Approach

Chosen: eager fragments export filtered to Season 1, captured at Garden.create() time, threaded through every simulateOneTick call via SimContext.

Trade-off vs. await loadSeasonFragments(1): the eager path is simpler — Phaser's create() is synchronous, so an await would require an async init dance (set an empty corpus, load, swap; or use init() + Promise + create() chaining). For Phase 2's Season-1-only scope, the eager path is the minimum-viable choice.

The PIPE-02 lazy structural plumbing is independently verified by check-bundle-split.mjs, so Phase 4+ Season-2 onboarding can swap to await loadSeasonFragments(currentSeason) (probably in init()) without re-litigating the architecture. Documented at src/game/scenes/Garden.ts:55 (the SimContext docblock).

Manual Smoke Test

Not performed in this execution session (sequential automated executor; user has not yet run npm run dev). The plan specifies the manual smoke as a recommended-but-optional executor step. Structural verification is comprehensive:

• 217/217 Vitest cases green (was 163 before this plan; +54 new — 16 selector, 18 commands extension, 7 Journal, 6 FragmentRevealModal, 3 journal-icon, 3 check-bundle-split, 1 commands rewording).
• npm run lint exits 0 (zero ESLint sim-purity violations; Pitfall 1 still mechanically defended).
• npm run build exits 0 (Vite parses all 17 fragments — schema violation would fail the build per PIPE-01).
• npm run ci exits 0 end-to-end with check:bundle-split integrated.
• Plan 02-05's Playwright e2e (PIPE-07) will exercise the full Begin → Plant → Grow → Harvest → reveal-modal → journal loop visually under a real browser.

Decisions Made

See key-decisions in frontmatter (8 entries). Headlines:

1. Pool exhaustion: sentinel fallback (season1.soil._exhaustion), not repeat-most-recent — preserves the no-dup invariant on harvestedFragmentIds.
2. Plant-type unlock thresholds: rosemary @ 0 / yarrow @ 3 / winter-rose @ 6 (Plan author's discretion within D-05; aligned with Lura beat cadence at 1/4/8).
3. Garden scene uses the EAGER fragments corpus filtered to Season 1, not loadSeasonFragments(1) await. Simpler synchronous create(); PIPE-02 lazy plumbing is structurally verified for Phase 4+ to exploit.
4. Compost beat content shipped (compost-acknowledgements.ink, 6 lines) but NOT yet rendered — Plan 02-04 owns the Ink runtime; Garden.ts has a TODO at the wiring point.
5. Journal-icon 'j' hotkey deferred to Plan 02-05 (Settings hotkey work).
6. FragmentRevealModal silent-dismiss on unresolvable id (defensive, single-step setState transition).
7. Knuth multiplicative hash for the seedHash spreads adjacent (count, tick) pairs across the 32-bit seed space.
8. Sentinel exclusion is dual-defended (schema-tag check + selector branch).

Deviations from Plan

None — the plan executed almost exactly as written. Two minor tightenings applied during authoring:

Tightenings (not deviations — within plan author's discretion)

1. Authored 17 fragments instead of the plan's "≥17 (≥14 yaml + ≥2 md + 1 sentinel)" target. Plan W6 fix called for ≥9 warm; shipped exactly 9 yaml-warm (plus the 1 lura-first-letter.md warm = 10 warm total when counting Markdown). Heavy pool sized to 2 yaml + 1 md = 3 (matches the conservative-but-deep ratio for late-game unlocks). All targets met or exceeded.
2. Added a journal-icon.test.tsx file (3 cases) the plan didn't explicitly request. The plan's task-2 acceptance criteria called for selectJournalRevealed to be referenced in the icon (verified by grep) but did not mandate Vitest coverage of the icon component. Adding 3 cases for ~20 LoC was cheap insurance and tightens the D-23 pre-first-harvest invisibility guarantee.

Neither tightening expanded scope or altered any architectural decision; both stayed within the plan's "Claude's discretion within reason" envelope.

Issues Encountered

None — the plan was unusually well-specified and the implementation matched it almost line-for-line. The only friction point was a transient: the original plan-text seedHash formula (harvestedFragmentIds.length * 2654435761 + tile.plant.plantedAtTick) sums two integers but does not coerce the result to 32-bit, which means very large pre-existing harvest counts would push the seed past Number.MAX_SAFE_INTEGER long-term. Added | 0 (32-bit signed-integer truncation) on the result; mulberry32 internally re-coerces to unsigned via >>> 0, so the final RNG output is unaffected. Documented in the harvest() docblock.

TDD Gate Compliance

This plan is type: execute, not type: tdd. No RED → GREEN → REFACTOR commit-sequence gating applies. Tests landed alongside implementation in Tasks 1–3.

User Setup Required

None — no external service configuration required. All work is in-tree TypeScript / authored content / a single Node ESM verification script.

Next Phase Readiness

• Plan 02-04 (Lura's Ink dialogue + gate beats): can build directly on top. Lura's Ink runtime swaps in for the compost-acknowledgements TODO at src/game/scenes/Garden.ts and for Lura's beat-fire surface (1st / 4th / 8th harvest gated by harvestedFragmentIds.length). The required unlockedPlantTypes and harvestedFragmentIds writes are now flowing through the store correctly.
• Plan 02-05 (offline catchup + letter + Settings + Playwright e2e): can build directly on top. The harvest pipeline produces real harvestedFragmentIds entries that Plan 02-05's offline auto-harvest path can append to; the Memory Journal already renders any id the offline path adds (verified by Journal.test.tsx — adding ids to the store re-renders the modal under Season 1).

No blockers, no IOUs, no carried-over technical debt this plan produced. The eager fragments corpus + Plan 02-02's INEFFECTIVE_DYNAMIC_IMPORT warnings remain — both inherited from Plan 02-02 with the same documented Plan 02-04+ resolution path.
