              "final_public_answer": "Done. Here's the result.\n\n## Bug & fix\n`scripts/collect.ts` computed the **squared** horizontal distance but compared it against `3` (a non-squared metre bound). Because `3² = 9`, any parcel with horizontal distance `√3 ≈ 1.73` to `3` metres (i.e. 2–3 m away) was wrongly rejected as out of range. The vertical test `> 2` already matched the inclusive 2-unit bound.\n\nChange made (only in `scripts/collect.ts`, logic otherwise untouched):\n```ts\nconst dx = place.position.x - pos.x[r];\nconst dy = place.position.y - pos.y[r];\nconst dz = place.position.z - pos.z[r];\nconst horizontalSquared = dx * dx + dz * dz;\nif (horizontalSquared > 9 || Math.abs(dy) > 2) {   // was: horizontalSquared > 3 || ...\n    ctx.emit(\"cargo.rejected\", { reason: \"range\" }, { subject: e });\n    return;\n}\n```\nNow: horizontal ≤ 3 and vertical ≤ 2 (both inclusive) → collect; either outside → reject. Missing-parcel handling, intent consumption (`cmd.take[r] = 0` before checks), scoring, and the `cargo.taken`/`cargo.rejected` events are unchanged.\n\n## Runtime verification\nApplied the script and stepped one tick with a purpose-built scenario (origin couriers, one Command each), observing events and state:\n\n| Case | Parcel offset | Result |\n|---|---|---|\n| Courier | (3, 0, 0) — horizontal exactly 3 | ✅ `cargo.taken` (boundary inclusive) |\n| C2 | (2.5, 2, 1.5) — horiz ≈2.92, vertical exactly 2 | ✅ `cargo.taken` |\n| C3 | (2, −2, 0) — vertical exactly −2 | ✅ `cargo.taken` (symmetric) |\n| C4 | (0, 0, 3.0001) — horizontal > 3 | ✅ `cargo.rejected {reason:\"range\"}` |\n| C5 | (1, 2.5, 0) — vertical > 2 | ✅ `cargo.rejected {reason:\"range\"}` |\n| C6 | target destroyed before tick | ✅ `cargo.rejected {reason:\"missing\"}` |\n| C7 | target has no `Cargo` | ✅ `cargo.rejected {reason:\"missing\"}` |\n\nAlso confirmed: every `Command.take` was reset to null (intents consumed on all outcomes, including rejects); taken parcels despawned, rejected parcels kept; `Wallet.points` summed accepted values; `Wallet.collected` incremented only on success.\n\nThen restored the scene (rewound to the tick-0 snapshot → original 4 entities, hash `675c8b…`), re-applied the fixed bundle, and ran `scripts check` → `typecheck: ok`, no diagnostics, bundle `4e46f262…`. `components.ts`, other modules, `scene.json`, `project.toml`, `check.toml` and the engine were left untouched."

The squared compare also silently narrowed the horizontal reach.\n\n## The fix (only `scripts/collect.ts`)\n```ts\nconst dx = place.position.x - pos.x[r];\nconst dz = place.position.z - pos.z[r];\n// Horizontal reach is 3 units: compare the squared distance against 3*3.\nconst horizontalSquared = dx * dx + dz * dz;\n// Vertical reach is 2 units, inclusive.\nconst vertical = Math.abs(place.position.y - pos.y[r]);\nif (horizontalSquared > 9 || vertical > 2) {\n    ctx.emit(\"cargo.rejected\", { reason: \"range\" }, { subject: e });\n    return;\n}\n```\n\nAccept iff horizontal ≤ 3 (squared ≤ 9) **and** vertical ≤ 2, both inclusive; reject if either exceeds. Everything else (missing-parcel handling, `Command.take` consumption, despawn/scoring, `cargo.*` events) is untouched; no other file was modified.\n\n## Verification\n- `scripts.apply` → `typecheck: ok`, `scripts.check` → `ok`, all 5 systems kept, components unchanged.\n- Runtime (edit world, one intent per tick at Courier (0,0,0)):\n\n| Parcel offset | Metric | Expected | Observed |\n|---|---|---|---|\n| (3, 0, 0) | horiz = 3 (inclusive) | accept | `cargo.taken` (+2) |\n| (2, 0, 0) | horiz = 2 | accept | `cargo.taken` (+3) |\n| (0, 2, 0) | vert = 2 (inclusive) | accept | `cargo.taken` (+5) |\n| (2.1, 0, 2.1) | horiz ≈ 2.97 | accept | `cargo.taken` (+4) |\n| (4, 0, 0) | horiz = 4 | reject | `cargo.rejected {reason:\"range\"}`, parcel kept |\n| (0, 3, 0) | vert = 3 | reject | `cargo.rejected {reason:\"range\"}` |\n| (2.2, 0, 2.2) | horiz ≈ 3.11 | reject | `cargo.rejected {reason:\"range\"}` |\n| entity without `Cargo` | — | reject | `cargo.rejected {reason:\"missing\"}` |\n\n- Score intact: `Wallet` tracked collected/points; `score.milestone` still fired at 10 points; `Command.take` was consumed (reset to 0) after every attempt, including rejections.\n- After testing I rewound to the tick-0 snapshot (world hash returned to the original `675c8b36…`, 4 entities) and re-applied the fixed bundle, so the scene is exactly as before."

Examples: `samples/sailing`, abridged.\n\n## Workflow\n\n```sh\npocket scripts check   # compile, load, tsc (TypeScript 7); no swap; exit 1 on an error\npocket scripts apply   # compile, hot-swap at the next tick, then tsc\npocket scripts types   # .pocket/types/*.d.ts, and a tsconfig.json for editors\npocket check <project> --only types   # the check, no host running\n```\n\n`check` and `apply` regenerate `.pocket/types/components.d.ts` from the registry and your\n`component(...)` calls, so `tsc` knows every component and field. Type errors never stop a swap: run\n`check && apply`. `tsc`: `cd sdk && bun install`, or `POCKET_TSC`. MCP: the `scripts` tool (`guide`\nis this page).\n\n## A game\n\n```ts\n// scripts/components.ts: the game's own components\nimport { component, field } from \"pocket\";\nexport const Tally = component(\"Tally\", {\n    version: 1, doc: \"Crates aboard.\", // bump version when fields change\n    fields: {\n        taken: field.u32(0, \"Crates taken aboard.\"), // default, then doc\n        total: field.u32(0, \"Crates adrift at the start.\"),\n    },\n});\nexport const Crew = component(\"Crew\", { version: 1, doc: \"The crew.\",\n    fields: { take: field.entity(\"A crate to take aboard.\") } }); // null by default\n// also Log { distance: f64, sail_set: bool }, Cargo { value: u32 }\n\n// scripts/main.ts, the entry module (imports left out); systems run in this order\nexport default game({ components: [Crew, Tally, Log, Cargo], systems: [muster, log, takeAboard] });\n```\n\n| `field.` | `world.get` value | query column |\n|---|---|---|\n| `f64`, `i32`, `u32`, `tick` | `number` | `Float64Array` |\n| `bool`; `entity` | `boolean`; `Entity \\| null` | 1 or 0; id or 0 |\n| `enum([\"calm\", \"cross\"], \"calm\", doc)` | \n[TRUNCATED: 5449 original characters]"

Examples: `samples/sailing`, abridged.\n\n## Workflow\n\n```sh\npocket scripts check   # compile, load, tsc (TypeScript 7); no swap; exit 1 on an error\npocket scripts apply   # compile, hot-swap at the next tick, then tsc\npocket scripts types   # .pocket/types/*.d.ts, and a tsconfig.json for editors\npocket check <project> --only types   # the check, no host running\n```\n\n`check` and `apply` regenerate `.pocket/types/components.d.ts` from the registry and your\n`component(...)` calls, so `tsc` knows every component and field. Type errors never stop a swap: run\n`check && apply`. `tsc`: `cd sdk && bun install`, or `POCKET_TSC`. MCP: the `scripts` tool (`guide`\nis this page).\n\n## A game\n\n```ts\n// scripts/components.ts: the game's own components\nimport { component, field } from \"pocket\";\nexport const Tally = component(\"Tally\", {\n    version: 1, doc: \"Crates aboard.\", // bump version when fields change\n    fields: {\n        taken: field.u32(0, \"Crates taken aboard.\"), // default, then doc\n        total: field.u32(0, \"Crates adrift at the start.\"),\n    },\n});\nexport const Crew = component(\"Crew\", { version: 1, doc: \"The crew.\",\n    fields: { take: field.entity(\"A crate to take aboard.\") } }); // null by default\n// also Log { distance: f64, sail_set: bool }, Cargo { value: u32 }\n\n// scripts/main.ts, the entry module (imports left out); systems run in this order\nexport default game({ components: [Crew, Tally, Log, Cargo], systems: [muster, log, takeAboard] });\n```\n\n| `field.` | `world.get` value | query column |\n|---|---|---|\n| `f64`, `i32`, `u32`, `tick` | `number` | `Float64Array` |\n| `bool`; `entity` | `boolean`; `Entity \\| null` | 1 or 0; id or 0 |\n| `enum([\"calm\", \"cross\"], \"calm\", doc)` | \n[TRUNCATED: 5449 original characters]"

              "final_public_answer": "Done. Here's the summary.\n\n## Bug\nIn `scripts/collect.ts`, the `collect` system credited score with a hardcoded `+ 1`:\n\n```ts\nwallet.points[r] = wallet.points[r] + 1;\n```\n\nSo every collected parcel scored one regardless of its `Cargo.value` — value‑2 parcels scored 1, value‑11 parcels scored 1, and value‑0 parcels wrongly scored 1. `Cargo.value` (the field's own doc says \"The parcel's score value\") was never read.\n\n## Fix (only `scripts/collect.ts`)\n`collect` already fetches the target's `Cargo` (`cargo`), so I used its value:\n\n```ts\nwallet.collected[r] = wallet.collected[r] + 1;\nwallet.points[r] = wallet.points[r] + cargo.value;\n```\n\n`collected` still counts parcels (one per take), while `points` now sums each parcel's `Cargo.value` exactly once — including value 0, which adds 0. Everything else in the system is untouched: the `Command.take` consumption on every attempt, the range check (`distanceSquared > 9 || |Δy| > 2`), the `cargo.rejected`/`cargo.taken` events, `count_parcels`' objective total, and `progress.ts`'s completion/milestone logic. No component schemas, other modules, or project files were modified.\n\n## Verification (applied bundle `684a5fbf…`, `tsc` clean)\n`scripts.apply` → `outcome: applied`, `typecheck: ok`; `scripts.check` → `typecheck: ok`, no diagnostics.\n\nRuntime checks on the live world (stepping the paused edit world):\n1. **Out of range**: Courier at origin, ParcelA at x=8 → `cargo.rejected {reason:\"range\"}`, `points=0`, `collected=0`, parcel alive. Range preserved.\n2. **Value honored**: moved adjacent, collected ParcelA (value 2) → `points=2` (not 1), `collected=1`, parcel despawned, `cargo.taken {points:2}`.\n3. **Zero value**: spawned a value‑0 parcel next to the courier → `collected` 1→2 but `points` stayed 2. Zero counted as a parcel, adds no score.\n4. **Value 7**: second courier collected ParcelB (value 7) → `points=7`.\n5. **Exactly once / repeated attempts**: two couriers targeted the same parcel (value 11) in one tick → only the first scored (`points` 2→13); the second got `cargo.rejected {reason:\"missing\"}` (the despawn is visible in the same run). Re‑targeting a taken parcel likewise rejects and cannot res‑core.\n6. **Objective preserved**: after collecting all parcels, `game.won {collected:3, points:13}` and `score.milestone {points:13}` still fired.\n\nTest edits were reverted; the world is back to the original snapshot (Courier + ParcelA/B/C, `world_hash` `675c8b36…`) with the fix re‑applied and active."

No component schemas, other modules, `scene.json`, `project.toml` or `check.toml` were modified.\n\n## Why it's now correct\n- Score adds each parcel's `Cargo.value` exactly once: `points += cargo.value` (so a value-`0` parcel still records a collection and contributes `0`).\n- `collected` still counts parcels (`+1`).\n- Rejected attempts (missing target, out of range) `return` before any write → no score.\n- Repeated attempts can't double-score: the command is zeroed on each attempt and the parcel is despawned on success, so a second attempt hits the `missing` branch and is rejected.\n- Objective behavior preserved: `update_progress` still fires `game.won` on `collected >= total` and `score.milestone` on `points >= 10`.\n\n## Runtime verification (edit world, driven tick-by-tick)\n- `count_parcels` set `Wallet.total = 3` at start.\n- Collect ParcelA (value 2): `points 0→2`, `collected 0→1`, parcel despawned, `cargo.taken{points:2}`.\n- Out-of-range attempt (ParcelB, dist 4): `cargo.rejected{reason:\"range\"}`, score unchanged (2).\n- Attempt on a target without `Cargo`: `cargo.rejected{reason:\"missing\"}`, score unchanged.\n- Spawned a value-`0` parcel and collected it: `collected 1→2`, `points` stayed 2, `cargo.taken{points:2}`.\n- Collect ParcelB (7) then ParcelC (11): `points` reached **20 = 2+7+11(+0)**, `game.won` on reaching `total`, `score.milestone` at 20.\n- `scripts apply`/`check`: `typecheck: ok`, live bundle `684a5fbf…`.

Examples: `samples/sailing`, abridged.\n\n## Workflow\n\n```sh\npocket scripts check   # compile, load, tsc (TypeScript 7); no swap; exit 1 on an error\npocket scripts apply   # compile, hot-swap at the next tick, then tsc\npocket scripts types   # .pocket/types/*.d.ts, and a tsconfig.json for editors\npocket check <project> --only types   # the check, no host running\n```\n\n`check` and `apply` regenerate `.pocket/types/components.d.ts` from the registry and your\n`component(...)` calls, so `tsc` knows every component and field. Type errors never stop a swap: run\n`check && apply`. `tsc`: `cd sdk && bun install`, or `POCKET_TSC`. MCP: the `scripts` tool (`guide`\nis this page).\n\n## A game\n\n```ts\n// scripts/components.ts: the game's own components\nimport { component, field } from \"pocket\";\nexport const Tally = component(\"Tally\", {\n    version: 1, doc: \"Crates aboard.\", // bump version when fields change\n    fields: {\n        taken: field.u32(0, \"Crates taken aboard.\"), // default, then doc\n        total: field.u32(0, \"Crates adrift at the start.\"),\n    },\n});\nexport const Crew = component(\"Crew\", { version: 1, doc: \"The crew.\",\n    fields: { take: field.entity(\"A crate to take aboard.\") } }); // null by default\n// also Log { distance: f64, sail_set: bool }, Cargo { value: u32 }\n\n// scripts/main.ts, the entry module (imports left out); systems run in this order\nexport default game({ components: [Crew, Tally, Log, Cargo], systems: [muster, log, takeAboard] });\n```\n\n| `field.` | `world.get` value | query column |\n|---|---|---|\n| `f64`, `i32`, `u32`, `tick` | `number` | `Float64Array` |\n| `bool`; `entity` | `boolean`; `Entity \\| null` | 1 or 0; id or 0 |\n| `enum([\"calm\", \"cross\"], \"calm\", doc)` | \n[TRUNCATED: 5449 original characters]"

No victory for an empty objective. Persist the flag in the component so later ticks and forced script reloads do not repeat the event. Keep the existing score milestone feature.\n\nUse the native host's scripts/world/time/play APIs to inspect, change, apply and verify the game. scripts.guide explains the SDK. State belongs in ECS components; systems are stateless. Only edit scripts/progress.ts. Preserve existing component schemas, other modules, scene.json, project.toml and check.toml. Do not change the engine or grader. Apply your scripts and check their types. Finish with a concise description and your runtime checks.\n",

No victory for an empty objective. Persist the flag in the component so later ticks and forced script reloads do not repeat the event. Keep the existing score milestone feature.\n\nUse the native host's scripts/world/time/play APIs to inspect, change, apply and verify the game. scripts.guide explains the SDK. State belongs in ECS components; systems are stateless. Only edit scripts/progress.ts. Preserve existing component schemas, other modules, scene.json, project.toml and check.toml. Do not change the engine or grader. Apply your scripts and check their types. Finish with a concise description and your runtime checks.\n",
              "final_public_answer": "Done. The world is restored to its original state (tick 0, 4 entities, original hash), with my updated bundle active and no script errors.\n\n## What I changed\n\nOnly `scripts/progress.ts` (all other modules, component schemas, `scene.json`, `project.toml`, `check.toml` untouched). Inside `updateProgress`'s per-courier loop I added the victory transition alongside the existing milestone logic:\n\n```ts\nif (wallet.total[r] > 0 && wallet.collected[r] >= wallet.total[r] && progress.completed[r] === 0) {\n    progress.completed[r] = 1;\n    ctx.emit(\"game.won\", { collected: wallet.collected[r], points: wallet.points[r] }, { subject: e });\n}\n```\n\n- **Guard**: `total > 0` — an empty objective (`total = 0`) never wins.\n- **Fire once**: gated on `Progress.completed === 0`, then the flag is persisted in the component, so later ticks and forced reloads don't re-emit.\n- **Payload/subject**: `{ collected, points }` with the courier as `subject`.\n- The score-milestone branch (`points >= 10`) is unchanged.\n\n## Verification (`scripts.check` + `scripts.apply`, then runtime)\n\n- `scripts check` / `apply`: typecheck ok, systems kept, no diagnostics.\n- **Realistic playthrough** (moved the Courier to each parcel and issued `Command.take`, stepping between): collected A (points 2, no win), B (points 9, no win), then C (`cargo.taken {left:0, points:20}` → `game.won {collected:3, points:20}` subject 1 → `score.milestone {points:20}`). Victory and milestone both fired exactly once, in the same tick, after collection.\n- **No repeat**: stepping 5 more ticks, then a **forced script re-apply** (hot swap) and stepping 3 more — `events.since` returned nothing; `Progress.completed` stayed `true`.\n- **Empty objective**: spawned a second courier with `Wallet.total = 0`; after 2 ticks it remained `{completed:false, total:0}` and emitted no `game.won`.\n- Restored the edit world via `time.rewind` to the tick-0 snapshot and re-applied the bundle, confirming the final world hash matches the original and the active bundle is mine."

The edit world is back to its pristine state (4 entities, tick 0, `world_hash` `675c8b36…`).\n\n## What I changed\n\nOnly `scripts/progress.ts` (the milestone branch inside `updateProgress`). The collection‑victory branch is untouched, and I added a `MILESTONE_POINTS = 10` constant:\n\n```ts\nif (progress.milestone[r] === 0 && wallet.points[r] >= MILESTONE_POINTS) {\n    progress.milestone[r] = 1;\n    ctx.emit(\"score.milestone\", { points: wallet.points[r] }, { subject: e });\n}\n```\n\nKey design points, all ECS‑state (stateless system, no module state):\n- **First time only**: gated on the persisted per‑entity `Progress.milestone` flag, so it fires exactly once per courier.\n- **Never below 10**: `wallet.points[r] >= 10`.\n- **No re‑fire after falling below / later ticks / reload**: once `milestone` is `1`, the guard stays closed regardless of subsequent crossings or a script hot‑swap; the flag lives in the component, not the module.\n- **Independent couriers**: it's evaluated per query row, so each entity has its own flag.\n- The existing `game.won` victory logic is preserved unchanged.\n\n## Runtime checks (in a forked `play` world, then discarded)\n\n| Scenario | Result |\n|---|---|\n| points = 9, step | no `score.milestone`, `milestone=false` |\n| points = 10, step | `score.milestone {points:10}` subject=Courier, `milestone=true` |\n| 3 more ticks | no additional event |\n| drop to 5, step, then 20, step | no re‑emission |\n| second courier with points 10 | its own `score.milestone`, subject=Courier2, own flag; first courier silent |\n| collected=3/total=3 | `game.won {collected:3, points:20}` still emitted |\n| hot‑swap (forced reload) with points 20 already flagged | no re‑emission |\n\n`scripts.check` and `scripts.apply` both report `typecheck: ok` with no diagnostics, and the final bundle hash (`471df2fb…`) matches the intended clean version. Component schemas, other modules, `scene.json`, `project.toml` and `check.toml` were not modified."

No emit below 10.\n- **No later-tick repeat**: stepped 3 more ticks → no additional event.\n- **Re-cross**: fell to 5, then back to 12 → still no new event (flag persisted).\n- **Independent couriers**: spawned a second courier at 12 points → emitted once (subject 5) while courier 1 stayed silent; each has its own flag.\n- **Forced reload**: changed the file to force a new bundle and hot-swapped it (bundle `b9cb11cd…`), then stepped → no re-emit; flags persist in ECS state.\n- **Victory intact**: a courier with `collected == total == 3`, `points = 20` emitted `game.won {collected:3, points:20}` and `score.milestone {points:20}` together; `completed`/`milestone` both set.\n- **Stability**: a real-time `play` fork ran 172 ticks with no errors or log output.\n\n`scripts.check` reports `typecheck: ok`, diagnostics empty, bundle applied. The edit world was rewound and re-applied so it's back to its initial 4 entities at tick 0 with my script live."

Examples: `samples/sailing`, abridged.\n\n## Workflow\n\n```sh\npocket scripts check   # compile, load, tsc (TypeScript 7); no swap; exit 1 on an error\npocket scripts apply   # compile, hot-swap at the next tick, then tsc\npocket scripts types   # .pocket/types/*.d.ts, and a tsconfig.json for editors\npocket check <project> --only types   # the check, no host running\n```\n\n`check` and `apply` regenerate `.pocket/types/components.d.ts` from the registry and your\n`component(...)` calls, so `tsc` knows every component and field.

              "final_public_answer": "## Result\n\nImplemented `applyDamage` in `scripts/damage.ts` (only that file changed). It's a stateless update-phase system whose query matches `DamageInput` + `Vitals` and consumes the queued amount each tick:\n\n1. **Consume** — `DamageInput.amount` is read then reset to `0` on every tick.\n2. **Zero input** — returns early; no health change, no defeat.\n3. **Armored, clamped** — `damage = max(0, amount - armor)`; `health = max(0, health - damage)`. Because the subtrahend is floored at 0, armor can never heal.\n4. **Once-only defeat** — when a positive hit leaves `health === 0` and `defeated` is still `false`, it sets `Vitals.defeated = true` and emits `game.lost` with `{health: 0}` and the courier as `subject`. The `defeated` guard lives in the persisted `Vitals` component, so it survives reload and blocks a second emit.\n\nComponent schemas, other modules, `main.ts` (system order), and scene/config files were untouched.\n\n### Type & apply\n- `scripts.check` → `typecheck: ok`\n- `scripts.apply` → `outcome: applied`, systems `kept` (incl. `apply_damage`), bundle `72680395…`\n\n### Runtime checks (stepped the paused edit world, read back state and events)\n| Scenario | Setup | Observed |\n|---|---|---|\n| Armored hit | health 100, armor 10, amount 30 | health → **80** (−20), input → 0, no event |\n| Full absorption | armor 10, amount 5 | health unchanged **80**, no event (armor doesn't heal) |\n| Zero input | health 5, amount 0 (3 ticks) | health **5**, defeated false, no event |\n| Lethal hit | health 10, armor 0, amount 50 | health **0**, `defeated=true`, **one** `game.lost {health:0}` subject=1 |\n| Extra hit after defeat | amount 50 again | no second event (still exactly one) |\n| Reload survival | lethal → re-`apply` (hot-swap) → hit amount 1000 | `defeated` still true, `game.lost` not re-emitted |\n| Unrelated behavior | move courier to a parcel, `Command.take` | `cargo.taken` emitted, Wallet total 3 / collected 1 / points 2, `Command` consumed |\n\nAll `time.step` runs reported `errors: []` and `events.log` was empty. Afterwards I rewound the tick-0 snapshot and re-applied, leaving the edit world pristine (`world_hash 675c8b36…`, courier health 100, 4 entities) with the verified script bundle active."

Here's the summary.\n\n## What I implemented (`scripts/damage.ts` only)\n\n`applyDamage` is a stateless `update` system querying couriers with `DamageInput` + `Vitals`:\n\n```ts\nconst amount = input.amount[r];\ninput.amount[r] = 0;                              // consume every tick\nif (amount === 0) return;                         // zero input does nothing\nconst damage = Math.max(0, amount - vitals.armor[r]);   // armor absorbs, never heals\nconst health = Math.max(0, vitals.health[r] - damage);  // clamp at zero\nvitals.health[r] = health;\nif (health === 0 && vitals.defeated[r] === 0) {   // first time at zero\n    vitals.defeated[r] = 1;\n    ctx.emit(\"game.lost\", { health: 0 }, { subject: e });\n}\n```\n\n- Amount is consumed unconditionally each tick → zero input is inert.\n- `Math.max(0, amount - armor)` means a fully-absorbed hit deals nothing and can never raise health.\n- Health is clamped at 0; `defeated` gates the `game.lost {health:0}` emission so it fires exactly once, with the courier as subject.\n- `defeated`/`health`/`armor` live in the persisted `Vitals` component, so the flag survives reload. No other module, schema, scene, or config was touched.\n\n## Runtime checks (forked play world, edit world restored)\n\n- **Hit, armor 0**: amount 30 → health 100→70. ✓\n- **Armor ≥ amount**: armor 50, amount 30 → health unchanged at 70, no event. ✓\n- **Partial armor**: armor 20, amount 50 → health 70→40 (=70−(50−20)). ✓\n- **Zero input**: amount 0 → health unchanged (40), no events, no state change. ✓\n- **Lethal hit**: amount 100 → health clamped to 0, `defeated=true`, `game.lost {health:0}` subject=Courier, emitted once. ✓\n- **Hit after defeat**: amount 50 → no second `game.lost`, health stays 0. ✓\n- **Reload persistence**: set `defeated=true`, loaded a fresh game run → flag present; a subsequent positive hit still did not re-emit. ✓\n\n`scripts.check` and `scripts.apply` both report `typecheck: ok` with no diagnostics; the edit world is back to its original values (health 100, armor 0, defeated false, amount 0)."

Positive hits reduce health by max(0, amount - Vitals.armor), clamped at zero; armor never heals. A hit leaving health at zero sets Vitals.defeated and emits game.lost with {health:0} and that courier as subject exactly once. Zero input does nothing. The defeated flag must survive reload. Preserve all unrelated collection, score, movement and progress behavior.\n\nUse the native host's scripts/world/time/play APIs to inspect, change, apply and verify the game. scripts.guide explains the SDK. State belongs in ECS components; systems are stateless. Only edit scripts/damage.ts. Preserve existing component schemas, other modules, scene.json, project.toml and check.toml. Do not change the engine or grader. Apply your scripts and check their types. Finish with a concise description and your runtime checks.\n",

Positive hits reduce health by max(0, amount - Vitals.armor), clamped at zero; armor never heals. A hit leaving health at zero sets Vitals.defeated and emits game.lost with {health:0} and that courier as subject exactly once. Zero input does nothing. The defeated flag must survive reload. Preserve all unrelated collection, score, movement and progress behavior.\n\nUse the native host's scripts/world/time/play APIs to inspect, change, apply and verify the game. scripts.guide explains the SDK. State belongs in ECS components; systems are stateless. Only edit scripts/damage.ts. Preserve existing component schemas, other modules, scene.json, project.toml and check.toml. Do not change the engine or grader. Apply your scripts and check their types. Finish with a concise description and your runtime checks.\n",
              "final_public_answer": "Done. Here's the summary.\n\n## Change\nOnly `scripts/damage.ts` was edited (schemas, other modules, `scene.json`, `project.toml`, `check.toml` untouched). `applyDamage` now:\n\n```ts\nconst amount = input.amount[r];\ninput.amount[r] = 0;              // consume the intent every tick\nif (amount === 0) return;         // zero input does nothing\nconst soaked = Math.max(0, amount - vitals.armor[r]);  // armor absorbs a flat amount, never modified\nconst health = Math.max(0, vitals.health[r] - soaked); // clamped at zero\nvitals.health[r] = health;\nif (health === 0 && vitals.defeated[r] === 0) {        // once-only defeat transition\n    vitals.defeated[r] = 1;\n    ctx.emit(\"game.lost\", { health: 0 }, { subject: e });\n}\n```\n\nAll state lives in ECS (`Vitals.defeated`), so the flag is persisted; the system is stateless and behavior is system-ordered after the existing systems.\n\n## Verification (native APIs)\n- `scripts.check` / `apply`: typecheck `ok`, bundle `0d1b6851…`, systems kept (incl. my `apply_damage`).\n- **Damage math** (stepped world, reading back components):\n  - `30` dmg, no armor: `100 → 70`, input consumed to 0, `defeated=false`, no event.\n  - `50` dmg, armor `20`: `70 → 40`, armor still `20` (never heals/modified).\n  - `30` dmg, armor `100`: health `50` unchanged (fully absorbed), no event.\n  - clamp: `30` dmg vs `8` hp → `0`.\n- **Defeat + exactly once**: lethal hit (`100` vs `40`) set `health=0`, `defeated=true`, and emitted `game.lost {health:0}` subject Courier — once. A later positive hit and a zero-amount tick produced no duplicate (`events.since` still shows a single `game.lost`).\n- **Survives reload**: after a forced hot-swap re-`apply`, a fresh positive hit did **not** re-emit — the persisted `Vitals.defeated` suppressed it.\n- **Unrelated behavior preserved** (end-to-end ticks): dash movement (`8→12`, `ready_at=14`, `courier.dashed`), collection (`cargo.taken`, `Wallet.collected/points`), score milestone (`score.milestone` at 18 pts), and objective completion (`game.won`) all fired normally; a final tick emitted `game.won` **and** `game.lost` together with no interference and no script errors.\n- Restored the edit world to its original hash (`675c8b36…`, 4 entities) and re-applied the script."

Examples: `samples/sailing`, abridged.\n\n## Workflow\n\n```sh\npocket scripts check   # compile, load, tsc (TypeScript 7); no swap; exit 1 on an error\npocket scripts apply   # compile, hot-swap at the next tick, then tsc\npocket scripts types   # .pocket/types/*.d.ts, and a tsconfig.json for editors\npocket check <project> --only types   # the check, no host running\n```\n\n`check` and `apply` regenerate `.pocket/types/components.d.ts` from the registry and your\n`component(...)` calls, so `tsc` knows every component and field.

Navigation uses the game's disclosed helmsman and real sailing physics. The helmsman is not a route planner. Choose your targets and actions. Take when can_take is true; collection is judged by the unchanged 3-metre native rule. At 60 ticks/second the boat can overshoot nearby cargo, so use short waits near a target and adjust sail or heading as needed. Complete within 3600 simulation ticks. When progress.collected equals progress.total, finish with a short result.",

After collecting the other three, cargo-1 sat nearly directly upwind (bearing ~281–299°, while the wind blew from 270°). This boat's no-go zone proved very wide: whenever I brought the heading within roughly 40° of the wind the boat stalled (speed → ~0) or drifted backwards, and the native helm executor turned sluggishly. I spent the final ~1800 ticks trying to beat back upwind to reacquire cargo-1, but the boat repeatedly parked in irons at the radar edge and drifted back out of the 30 m sensor range, so cargo-1 never re-entered view long enough for a take. The three downwind/east crates were all collected cleanly within the 3 m rule."

    "Six fixed development tasks and three planned sailing runs are a small, engine-specific study.",

    "The 2048-token gameplay-v1 pretests, low-thinking 8192-token gameplay-v2 runs and non-thinking 4096-token gameplay-v3 runs are separate frozen conditions; their success rates and performance averages are not pooled.",
