+** Writing Claude Skills
+
+Skill descriptions are routing keys — they determine whether a skill activates. Guidelines (ref: https://stevekinney.com/writing/agent-skills):
+- Open with =TRIGGER on:= and numbered conditions so activation is unambiguous
+- One specific job per skill; overlapping descriptions cause routing competition
+- Scope exclusions: state what the skill does NOT replace to prevent false positives
+- Domain-specific language; no generic phrases like "helps with X"

+** Architecture
+Static site (no backend). ~index.html~ + ~life.js~ + ~schedule.js~ as ES modules. Three.js + onnxruntime-web from CDN.
+Served by Caddy via ~nix run~ on port 8080. Built by ~nix build~ (includes model weights in ~$out/model/~).
+
+Domains:
+- *Life generation*: ~life.js~ — deterministic 36,500-day procedural simulation → [[id:9465af82-4383-466c-bf09-5be19c328f0b][trmn/life]]
+- *NPC people*: family tree + tracked friends/children, each with deterministic PersonRecord → [[id:423cac95-a80d-4db6-8bef-14297fb38437][trmn/people]]
+- *Daily schedule*: ~schedule.js~ — 96-slot day, 68 scenes, deterministic from (masterSeed, currentDay) → [[id:ff8aa6b7-61ff-444c-9301-c0b666b0b573][trmn/schedule]]
+- *Rendering*: Three.js low-poly 3D scenes, flat shading, cinematic 2.39:1 viewport
+- *LLM dialogue*: TinyStories-8M ONNX INT8 bundled in ~/model/TinyStories-8M/~ → [[id:4b44cf43-6106-4498-81a3-b23ebb25dabf][trmn/llm]]
+- *Assets*: SVG face sprites + GLB objects → [[id:4d5e6bc8-32eb-469f-a69f-84b14458c55b][trmn/assets]]
+
+~window.__life~ exposes ~{traits, buf, eventLog, people, today, currentDay, masterSeed, schedule}~.
+
+** Conventions
+- Determinism: ALL randomness seeded from absolute time, never ~Math.random()~; use ~makeRng(masterSeed, day)~
+- Low-poly aesthetic: ~MeshLambertMaterial~ with ~flatShading: true~, BoxGeometry for characters
+- Cinematic viewport: ~aspect-ratio: 2.39/1~, FOV 26°, vignette via CSS ~::after~
+- Scene background via CSS gradient on ~#stage~ div; canvas is ~alpha: true~
+- Static assets: copy to ~$out/assets/~ in flake installPhase; generated assets built via Node.js in buildPhase
+
+** Gotchas
+- ~header Content-Type text/html~ in Caddyfile is wrong for multi-asset setups — omit it
+- ~MeshFlatMaterial~ does not exist; use ~MeshLambertMaterial { flatShading: true }~
+- ~onnxruntime-web~ must be a ~<script>~ tag (global), NOT an ES module importmap entry
+- Never spread ~buf~ (Float32Array) in a loop — hangs browser; index directly with ~buf[d * FIELDS + F.X]~
+- Nix flake ~src = ./.~ only includes git-tracked files → ~git add~ new dirs before ~nix build~
+- eventLog entries are ~{id, personId?, attended?}~ objects, not plain strings — use ~e.id~ not ~e~

+
+** Architecture
+Two asset types, both served from ~$out/assets/~ by Caddy:
+- *Sprites*: SVG files in ~assets/sprites/{eyes,nose,mouth}/~, static/committed, no build step
+- *3D objects*: GLB files in ~assets/objects/~, generated during ~nix build~ by Node.js scripts in ~scripts/~
+
+Face compositing at runtime: load SVG parts → draw onto ~OffscreenCanvas(128,128)~ → ~THREE.CanvasTexture~.
+Applied to the +z front face (index 4) of the head ~BoxGeometry~ via a material array.
+
+** Conventions
+- All sprite SVGs are 128×128; each draws its feature in the region it occupies on the face canvas
+  (eyes ~y≈35–55~, nose ~y≈65–85~, mouth ~y≈90–110~) so all layers composite with ~drawImage(img, 0, 0, 128, 128)~
+- Face part selection seeded from ~window.__life.masterSeed~ via inline ~mulberry32~ in the Three.js script block
+- ~window.__life~ exports ~masterSeed~ (added alongside traits/buf/eventLog/today/currentDay)
+- GLB generators: pure Node.js stdlib only (no npm), accept output path as ~process.argv[2]~
+- Three.js importmap includes ~"three/addons/": "https://cdn.jsdelivr.net/npm/three@0.160.0/examples/jsm/"~ for GLTFLoader
+
+** Gotchas
+- *Critical*: Nix flake ~src = ./.~ only includes git-tracked files (~git ls-files~).
+  New ~assets/~ and ~scripts/~ dirs must be ~git add~-ed before ~nix build~ or they are silently excluded.
+- ~BoxGeometry~ material array face order: ~[+x, -x, +y, -y, +z, -z]~ → index 4 is the front face (camera-facing)
+- GLB generator runs in Nix buildPhase and writes to the build dir; installPhase ~cp -r assets $out/assets~ picks up both committed sprites and the generated ~book.glb~
+
+** Key Files
+- ~assets/sprites/eyes/eyes_{1,2}.svg~ — wide-open vs narrow/tired eyes
+- ~assets/sprites/nose/nose_{1,2}.svg~ — dot vs nostrils nose
+- ~assets/sprites/mouth/mouth_{1,2}.svg~ — smile vs neutral mouth
+- ~assets/objects/book.glb~ — generated at build time (not committed); dark-red flat box 0.14×0.18×0.03
+- ~scripts/gen-book.mjs~ — pure Node.js GLB writer, no npm deps; ~node scripts/gen-book.mjs <outpath>~

+State is packed into ~Float32Array(DAYS * FIELDS)~ (~3.2MB). ~eventLog~ is ~Map<day, Array<{id, personId?, attended?}>>~ (entries are objects, NOT plain strings — changed when NPC system was added). ~people~ is ~Map<personId, PersonRecord>~ for all tracked NPCs. ~window.__life~ exposes ~{ traits, buf, eventLog, people, today, currentDay, masterSeed }~.
+
+** PRNG
+mulberry32 seeded per-day via splitmix32 hash:
+#+begin_src js
+makeRng(masterSeed, day)  // derives seed from hash(masterSeed ^ day*0x9e3779b9)
+#+end_src
+- ~Math.imul~ throughout — bitwise-identical on all IEEE-754 JS engines
+- Any day independently computable; no need to simulate prior days
+- masterSeed = ~(Date.now() / 1000) | 0~ (wall-clock seconds)
+- Reserved day slots: ~-1~ = protagonist traits; ~-2~ = family layout offsets (NPC system)
+- NPC streams are fully isolated — see [[id:423cac95-a80d-4db6-8bef-14297fb38437][trmn/people]]

+
+Fixed-at-birth traits (not packed): ~sex, introversion, ambition, resilience, baseHealth~
+Internal-only (not packed): ~friendList, friendLifetimeIndex, childrenList, childLifetimeIndex~
+
+** Scheduled Events (deterministic)
+birth(0), kindergarten(1826), primary(3652), middle(5113), hs_grad(6575), college_grad(8036), retirement(23725), death_cap(36500)
+Plus dynamically injected ~sibling_born~ entries (built inside ~simulateLife()~, merged + sorted into ~mergedSchedule~).
+
+** Random Events (31 total, evaluated in priority order, cap 2/day)
+Categories: death, disaster, health, financial, relationship, family, career, social
+Death uses Gompertz curve: ~0.000008 * exp((age-40)/60 * 5) * healthMod * resilienceMod~
+NPC-triggered events (not in EVENTS array): ~family_member_death~ (day loop step 4), ~friend_death~ (post-apply of lose_friend)
+
+** Gotchas
+- NEVER spread ~buf~ inside a loop — ~[...buf]~ on 800k-element Float32Array per iteration hangs the browser. Use ~buf[d * FIELDS + fieldIdx]~ directly.
+- ~life.js~ must be listed in ~flake.nix~ installPhase (~cp $src/life.js $out/~) or Caddy serves a 404.
+- eventLog entries are now ~{id, personId?, attended?}~ objects — any consumer using ~evs.includes('event_id')~ or ~counts[ev]~ will silently break. Use ~e.id~.
+- ~breakup~ and ~marry~ both have weight 0.0008/day → equal competition → many characters die "in relationship, not married". May need tuning.
+- "Unexpected end of input" on ~import('./life.js')~ usually means 404 (not rebuilt yet), not a real syntax error.
+
+** Console Snippets
+#+begin_src js
+// Import and run
+const { simulateLife, getDay, DAYS, FIELDS } = await import('/life.js');
+const sim = simulateLife(42);
+
+// Readable timeline (eventLog entries are objects now)
+const timeline = [...sim.eventLog.entries()].map(([d, evs]) => ({
+  age: (d / 365.25 | 0), day: d, events: evs.map(e => e.id).join(', ')
+}));

+);
+
+// Find death day (safe — no buf spreading)
+const death = Array.from({length: DAYS}, (_, d) => d).find(d => d > 0 && sim.buf[d * FIELDS] === 0);
+console.log('died age', death && (death / 365.25 | 0));

+
+** Purpose
+NOT a user-facing chat feature. This is infrastructure for *automatic procedural dialogue* between
+characters in the show. The chat panel was a test harness only. Future use: generate spoken lines
+for characters as part of the deterministic life-simulation loop.
+
+** Architecture
+In-browser LLM weights bundled into the site via ~nix build~. No backend, no external inference at runtime.
+
+Model: ~roneneldan/TinyStories-1M~ — GPT-Neo architecture, ~model_type: "gpt_neo"~,
+hidden=64, vocab=50257 (GPT-2 BPE tokenizer). Output is surreal/nonsensical children's story prose —
+intentionally acceptable for this project.
+
+Final ONNX INT8 size: *15 MB* (well under Cloudflare Pages 25 MiB per-file limit).
+
+Runtime stack:
+- ~onnxruntime-web~ loaded as a global ~<script>~ tag (not ESM importmap)
+- ~@huggingface/transformers~ AutoTokenizer only (no pipeline) — tokenizer files served from ~/model/TinyStories-1M/~
+- Custom top-k generation loop in JS; no KV cache (full sequence re-processed each step)
+
+** Deployment constraint
+Cloudflare Pages has a *25 MiB per-file limit*. This is why TinyStories-1M (15 MB) was chosen over 8M (40 MB).
+TinyStories-8M's embedding alone (50k vocab × hidden=256 × FP32) is ~52 MB; ~quantize_dynamic~ can't touch it
+(Gather op). TinyStories-1M's hidden=64 makes the embedding 4× smaller.
+
+** Conventions
+- ONNX model has ONLY ~input_ids~ (int64) as input; output: ~logits~ (float32 [1, seq, 50257])
+- ~attention_mask~ is NOT an input to the exported ONNX graph (was patched away during tracing)
+- Tokenizer: ~env.localModelPath = '/model/'; env.allowRemoteModels = false; AutoTokenizer.from_pretrained('TinyStories-1M')~
+- Prompt must be story-style: ~`A man was asked "${text}". He smiled and said, "`~
+  - Do NOT use dialogue-format prompts like ~"you: X\nhim: "~ — model immediately predicts ~\n~, empty output
+- Stop: first complete sentence ~(/^(.*?[.!?])/s)~ on decoded text with ~"~ stripped (~replace(/"/g, '')~)
+- Top-k=40, temperature=0.9, max 60 new tokens
+
+** Gotchas
+*Nix build:*
+- Do NOT use ~optimum~ — use ~torch.onnx.export~ directly with ~dynamo=False~
+- Add ~onnxscript~ to nativeBuildInputs (PyTorch 2.12 lazily imports it even for legacy export)
+- Patch ~create_causal_mask~ to ~lambda **kwargs: None~ before tracing (transformers 5.5.4 incompatibility)
+- ~quantize_dynamic~ skips Gather (embedding) — the embedding dominates file size for large vocab models
+- Tokenizer files (~tokenizer.json~, ~tokenizer_config.json~, ~special_tokens_map.json~) are identical
+  between TinyStories-1M and 8M — same GPT-2 BPE tokenizer; only ~config.json~ and ~pytorch_model.bin~ differ
+- nativeBuildInputs: ~transformers onnxruntime onnxscript torch~ (no optimum)
+
+*JS runtime:*
+- Load ~onnxruntime-web~ via ~<script>~ tag BEFORE the importmap/module scripts
+- Only pass ~input_ids~ to ~session.run()~ — passing ~attention_mask~ throws INVALID_ARGUMENT
+- Generation is slow (no KV cache): each step re-runs full accumulated sequence
+
+** Key Files
+- ~flake.nix~ — tinyStoriesOnnx sub-derivation: fetchurl + torch.onnx.export + quantize_dynamic
+- ~index.html~ — Two separate module scripts: Three.js scene + inference (ort global + AutoTokenizer)

+
+** Architecture
+Each NPC is a ~PersonRecord~ stored in ~people: Map<personId, PersonRecord>~ returned by ~simulateLife()~.
+Family is generated at the top of ~simulateLife()~ via ~generateFamily(masterSeed)~ before the day loop.
+Friends/children are created lazily via post-apply hooks when their triggering events fire.
+
+#+begin_src js
+PersonRecord {
+  id, role,          // e.g. 'mother', 'sibling_0', 'friend_3', 'child_0'
+  seed,              // uint32, derived from masterSeed + role salt
+  sex,               // 0=female 1=male
+  birthDay,          // days from protagonist day 0 (negative = already born)
+  deathDay,          // days from protagonist day 0
+  hairType,          // 0–3
+  hairColor,         // 0–3
+  eyeColor,          // 0–3
+  // friends only:
+  metOnDay?,         // day protagonist gained this friend
+  lostOnDay?,        // day the friendship ended
+  lostCause?,        // 'death' | 'drifted' | 'moved'
+}
+#+end_src
+
+** PRNG Isolation
+Protagonist's daily stream (~makeRng(masterSeed, d)~) is NEVER consumed by NPC logic.
+NPC logic uses two isolated streams:
+- Each NPC's own rng: ~makeNpcRng(deriveNpcSeed(masterSeed, salt))~ — for visual attrs + death age
+- Shared per-day NPC stream: ~makeRng(deriveNpcSeed(masterSeed, 0xffff0000), d)~ — for attendance rolls and lose_friend cause/pick rolls
+
+Reserved day slots: ~day = -1~ (protagonist traits, existing), ~day = -2~ (family layout offsets, new).
+
+#+begin_src js
+const ROLE_SALTS = {
+  mother: 0x00010000, father: 0x00020000,
+  maternal_grandmother: 0x00030000, maternal_grandfather: 0x00040000,
+  paternal_grandmother: 0x00050000, paternal_grandfather: 0x00060000,
+  sibling_0..3: 0x00070000–0x000a0000,
+  // friends:   0x01000000 + friendLifetimeIndex
+  // children:  0x02000000 + childLifetimeIndex
+  // npc-stream: 0xffff0000
+}
+#+end_src
+
+~deriveNpcSeed(masterSeed, salt) = splitmix32(splitmix32(masterSeed) ^ salt)~
+
+** Death Age Sampling
+Algebraic Gompertz inverse-CDF — no per-NPC simulation loop needed:
+#+begin_src js
+function sampleDeathAge(rng) {
+  const healthOffset = (rng() - 0.5) * 15;           // draw 1
+  const u = clamp(rng(), 0.001, 0.999);               // draw 2
+  const t = Math.log(1 - (Math.log(1-u) * 0.095 / 0.0003)) / 0.095;
+  return Math.round(clamp(t + healthOffset, 1, 108));
+}
+#+end_src
+Draw order per NPC rng: sex → hairType → hairColor → eyeColor → healthOffset → u (sampleDeathAge).
+
+** Post-Apply Hooks (inside simulateLife day loop)
+After ~Object.assign(s, ev.apply(...))~, five events trigger NPC record creation/mutation:
+- ~gain_friend~ → create PersonRecord, push to ~s.friendList~, increment ~s.friendLifetimeIndex~
+- ~lose_friend~ → splice from ~s.friendList~, roll cause (death 20% / drifted 50% / moved 30%); if death, upgrade eventLog entry from ~lose_friend~ to ~friend_death~
+- ~move_city~ → splice last min(5, friendList.length) friends, mark lostCause='moved'
+- ~first_child~ / ~subsequent_child~ → create child PersonRecord, push to ~s.childrenList~
+
+State additions to ~defaultState()~: ~friendList [], friendLifetimeIndex 0, childrenList [], childLifetimeIndex 0~
+(These are not packed into the Float32Array buffer; only ~friendCount~ / ~numChildren~ are packed.)
+
+** Family Generation
+~generateFamily(masterSeed)~ uses ~makeRng(masterSeed, -2)~ to draw birth offsets:
+- Mother: 20–35 years before protagonist; Father: 20–38 years before
+- Each grandparent: 20–35 years before their respective parent
+- Siblings: 0–3, each within ±8 years of protagonist (some already born at day 0, some born later)
+Grandparents with ~deathDay < 0~ were dead before protagonist was born — valid, just not triggering events.
+
+** Events
+- ~sibling_born~ (scheduled) — fires on sibling's birthDay if > 0; no state change, just logged with ~personId~
+- ~family_member_death~ (loop, step 4) — fires when any non-friend NPC's ~deathDay === d~; logged with ~personId~ and ~attended~ (70% probability)
+- ~friend_death~ (post-apply of lose_friend) — replaces ~lose_friend~ in eventLog when cause roll < 0.20
+
+** Gotchas
+- ~stats.mjs~ and any eventLog consumer must use ~e.id~ not ~e~ directly — entries are now ~{id, personId?, attended?}~ objects, not strings. Broke three spots in stats.mjs (all fixed).
+- ~friendList~ and ~friendCount~ are kept in sync manually after every mutation. If they diverge, prereq ~friendCount > 0~ fires ~lose_friend~ but ~friendList~ is empty → guard: ~if (ev.id === 'lose_friend' && s.friendList.length > 0)~.
+- Friend ~birthDay~ can be positive (friend younger than protagonist). At young protagonist ages (age 2), the ±15yr range means some friends haven't been born yet at meeting time. Cosmetic only — not used in any gameplay logic.
+- ~sibling_born~ uses a dynamically built ~mergedSchedule~ (SCHEDULED + sibling events, sorted). The existing static SCHEDULED array is unchanged.

+** Architecture
+~schedule.js~ is a standalone ES module that exports:
+- ~generateDaySchedule(today, traits, dayEvents, currentDay, masterSeed)~ → ~ScheduleEntry[]~
+- ~SCENES~ — plain object catalog of all ~68 scenes
+- ~slotToTime(slot)~ → ~"HH:MM"~ string (slot 0 = 06:00)
+- ~SLOTS~ (96), ~SLOT_MIN~ (15)
+
+~ScheduleEntry~: ~{ slot, duration, sceneId, location, label }~. Array is sorted by slot, non-overlapping, always covers all 96 slots with no gaps (builder fills remainder with ~sleep~).
+
+RNG isolation: schedule uses ~makeRng(masterSeed, currentDay + 50000)~. Offset of 50,000 clears the life sim's 0–36,500 range — no interference with protagonist daily streams.
+
+~window.__life~ exposes ~{ ..., schedule }~ alongside ~buf~, ~eventLog~, ~people~.
+
+** Slot Layout
+#+begin_example
+Slots  0–11   06:00–09:00   morning routine      (12 slots)
+Slots 12–23   09:00–12:00   early daytime        (12 slots)
+Slots 24–43   12:00–17:00   afternoon            (20 slots)
+Slots 44–55   17:00–20:00   early evening        (12 slots)
+Slots 56–63   20:00–22:00   late evening          (8 slots)
+Slots 64–95   22:00–06:00   sleep                (32 slots)
+#+end_example
+
+** Life Stage Detection
+~detectLifeStage(today, age)~ → one of 10 tags, checked in priority order:
+~very_sick~ (sick + health<25) → ~sick~ → ~toddler~ (age<5) → ~kindergarten~ (eduStage=1) → ~school~ (eduStage=2/3) → ~college~ (inCollege) → ~retired~ → ~worker~ (employed) → ~unemployed~ (age≥16) → ~child~
+
+** Forced Events
+Events in ~dayEvents~ (from ~eventLog.get(currentDay)~) that override normal blocks:
+| Event ID | Override |
+|---|---|
+| ~illness_acute~ | daytime → rest_in_bed; skip work/school |
+| ~serious_accident~ / ~injury_serious~ | afternoon → emergency_room |
+| ~first_child~ / ~subsequent_child~ | daytime → hospital_stay |
+| ~marry~ | afternoon → wedding_ceremony; evening → wedding_reception |
+| ~family_member_death~ (attended=true) | afternoon → funeral_ceremony + wake |
+| ~move_city~ | full day → moving_boxes |
+| ~premature_death~ | minimal day, idle |
+
+** Gotchas
+- ~jobCategory~ is NOT in the packed ~Float32Array~ buffer (not a field in ~F~). Schedule derives a stable per-character type from ~makeRng(masterSeed ^ 0x5A5A5A5A, 0)~. This is deterministic per character but may not match what was rolled in the life sim.
+- Young-child stages (~toddler~, ~kindergarten~, ~school~, ~child~) must be branched BEFORE adult defaults in morning and evening blocks. The ~isYoungChild~ flag gates: no ~make_breakfast~, no ~cook_dinner~, no ~morning_coffee~, no ~morning_exercise~. The adult fallthrough path always ran these — easy to regress.
+- ~go_to_park_with_parents~ is from the CHILD's perspective; ~hasYoungChildren~ is from the PARENT's perspective. They are mutually exclusive: ~hasYoungChildren = numChildren > 0 && age < 40~.
+- The schedule builder (~makeBuilder~) clamps at slot 96: ~push~ is a no-op once cursor ≥ SLOTS. ~fill(sceneId, toSlot)~ is safe to call even if cursor is already past ~toSlot~.
+
+** Debug Tool
+~schedule-debug.mjs~ — CLI tool, ~nix run .#schedule~
+- No args: random seed + random day from character's living years, full output
+- Prints seed, day, age, full state, traits, events, then schedule table
+- All state fields overridable: ~--seed~, ~--day~, ~--age~, ~--health~, ~--sick~, ~--employed~, ~--retired~, ~--married~, ~--children~, ~--friends~, ~--job-tier~, ~--loneliness~
+- ~--event <id>~ injects a forced event (repeatable); injected events are labelled ~(injected)~ in output
+- ~--help~ prints usage
