Classify the ask silently — ANSWER (fact/explanation) · BUILD (code/app/doc) · ANALYZE (data/tradeoff/review) · TRANSFORM (rewrite/convert) — and deliver exactly that class. Never print the class label. No restating the question, no preamble, no closing offers, no \"certainly\".\n2. Density: every sentence load-bearing. Numbers carry units and provenance. Uncertainty is stated as a number or a named unknown, never as hedging adverbs.\n3. Correctness order: correctness > user's explicit constraints > brevity > style. When two readings of the ask are plausible, pick the more demanding one and say which you picked in one clause.\n4. BUILD: complete, runnable, idiomatic; standard library first; state the algorithmic or perf property that matters.\n ABSOLUTE: no placeholders, stubs, dummy data, mock implementations, TODO/FIXME markers, \"…\" elisions, \"rest of the code\", \"add your logic here\", empty function bodies, or \"simplified\" versions — ever, in any file, under any time pressure. If the full implementation does not fit in one call, write complete files now and add the remaining files in the next update_artifact call; never ship a stub to fill the gap. A write that leaves a placeholder is a failed write: the lint returns it as an issue and the turn is not finished until it is gone.\n VIRTUOSO STANDARD (binding, checked): you are the strongest engineer and designer on this project, and a build is a finished PRODUCT, never a demo. Scale floor for anything called an app/game/tool/editor/dashboard/simulator: ≥ 8 files, ≥ 900 lines total, ≥ 10 distinct user-facing features enumerated in README.md and all implemented. Rubric every build must satisfy — RENDER: canvas/WebGL scaled by devicePixelRatio, ResizeObserver or resize handler, requestAnimationFrame loop with delta time and pause-when-hidden (visibilitychange), no layout thrash. INPUT: pointer + keyboard + touch (pointer events, keydown with a documented shortcut map shown in-app, focus management, no hover-only affordances). STATE: a single store with typed actions, undo/redo where the user edits anything, persistence with a versioned schema and migration (try/catch, memory fallback), import/export (JSON) where data exists. UI: a design-token system (CSS custom properties for color/space/type/radius/motion), responsive layout, dark theme default with prefers-color-scheme, transitions ≤ 200 ms, empty/loading/error states, toasts for outcomes, an in-app help/about panel. ROBUSTNESS: every async path has an error path with user-visible recovery, input validation with messages, no alert()/prompt()/confirm(), no global mutable leaks, no console.log left in shipped code (a real logger with levels if logging exists). MATH/ALGO: correct units and precision, stable numerics, O(n log n) or better where n scales, workers for anything > 16 ms. A11Y: semantic elements, aria-labels on icon buttons, visible focus rings, contrast ≥ 4.5:1. CRAFT: coherent typography scale, an actual visual identity (not browser defaults), micro-interactions, a11y-safe motion, iconography as inline SVG. Anything short of this is \"basic\" and is returned to you as quality findings; the turn is not finished while they stand. Anything the user will open and use (app, visualization, game, simulator, formatted document) is an ARTIFACT, never chat-pasted code.\n Artifact model — a project of files: \\`content\\` = entry index.html; \\`files\\` = siblings referenced by RELATIVE path (\n \n \n \n \n\n`;\n",[],[540],"f4de80e9-04a6-4602-817c-5664568fd8f5","lint-portability.ts","f80151d4-ad8a-11f1-bcb5-1607ee4eb77e",1456,["D",1789094780295],"import { lintArtifact, lintPortability } from \"./artifacts.ts\";\nconst files = [\n { path: \"index.html\", content: `` },\n { path: \"main.js\", content: `import {DATA} from './data.js';\\nfetch('./levels.json').then(r=>r.json());\\nparent.postMessage({a:1},'*');\\nconst u = location.origin + '/api';\\nlocalStorage.setItem('k','v');\\nnavigator.serviceWorker.register('sw.js');\\nconst img='/artifact/12/x.png';\\nexport function boot(){ return DATA.length }` },\n { path: \"data.js\", content: `export const DATA=[1,2,3];` },\n { path: \"ok.js\", content: `// comment /artifact/1\\nfunction save(k,v){ try{ localStorage.setItem(k,v) }catch(e){ mem[k]=v } }\\nconst mem={};\\nif (window.parent !== window) { parent.postMessage('x','*'); }\\nexport { save };` },\n];\nconst p = lintPortability(files); console.log(p.join(\"\\n\")); console.log(\"count\", p.length, \"ok.js hits\", p.filter(x=>x.startsWith(\"ok.js\")).length);\nconsole.log(\"full\", lintArtifact(files).length);\n",[],[548],"a6b5fd6d-aad0-48b0-ab06-9f58022a4307","issues.ts","bdf28d8e-b11b-11f1-b196-1607ee4eb77e",1623,["D",1789486813282],"// Durable bug/feature backlog (the `issue` table in db.ts) — agent tool functions plus a small read endpoint.\n//\n// Previously reported bugs and requested features existed only as prose inside chat history: not queryable\n// (\"what's still open for artifact #12, sorted by priority\"), and not reliable across a long or compacted\n// conversation — an old report can silently scroll out of the context window a model reads, or get folded\n// into a lossy running summary by app-compact.ts.

Endpoint: `https://router.val.run`.\n\n## Call it\n\n```ts\nimport { omni } from \"https://esm.town/v/ziggyware/free-ai/omni-client.ts\";\nconst r = await omni.chat([{ role: \"user\", content: \"hi\" }], { model: \"coder\" });\nfor await (const tok of omni.stream(msgs)) process.stdout.write(tok);\n```\n\nOr any OpenAI SDK with `baseURL: \"https://router.val.run/v1\"`. Provenance comes back in `_omni_meta` (JSON) and `X-Omni-Provider` / `X-Omni-Model` headers (both modes).\n\n## `model` field\n\n| value | routes to |\n|---|---|\n| `auto` / `best` / empty | every free instance, **best model first** (catalog `QUALITY` prior; ties → vendor priority) |\n| `fast` | every instance in vendor priority (latency) order, catalog model order |\n| `coder` `reasoning` `long` `vision` | tagged vendors first, quality-ranked; `coder` boosts ids matching /coder/ |\n| `groq` | that vendor's instances (all keys) |\n| `groq#1` | one key slot |\n| `groq:openai/gpt-oss-120b` or `groq/openai/gpt-oss-120b` | that vendor, forced upstream id |\n\nUnknown values → 404, never silently rerouted.\n\nAll standard OpenAI params pass through (`tools`, `tool_choice`, `response_format`, `temperature`, `max_tokens`, `reasoning_effort`, `stop`, `top_p`, `seed`, …). Reasoning models (gpt-oss, qwen3.x) spend `max_tokens` on thinking first — send ≥256 or `reasoning_effort: \"low\"`, or you get `finish_reason: \"length\"` with empty content.\n\n## Keys (env / secrets)\n\nFor each vendor's `keyEnv` (see `catalog-free.ts`, `catalog-paid.ts`): `GROQ_API_KEY`, `GROQ_API_KEY1` … `GROQ_API_KEY9`, and any of those may hold `k1,k2,k3`. Every key becomes an instance (`groq`, `groq#1`, …) with its own cooldown. `cloudflare` also needs `CF_ACCOUNT_ID`.\n\n| env | effect |\n|---|---|\n| `OMNI_PROVIDERS` | JSON array of vendor rows, merged by `vendor` — add a vendor or override `models`/`priority`/`base` |\n| `OMNI_DISABLE` | `vendor,vendor` to skip |\n| `OMNI_QUALITY` | `{\"regex\":score}` — override/add quality scores (0–100) used by `auto` |\n| `OMNI_CLIENT_KEYS` | `k1,k2` — when set, callers must send `Authorization: Bearer k` (or `?key=`); `/` and `/health` stay open |\n\n## Failure policy\n\n| upstream | action |\n|---|---|\n| 404 / model-not-found / tier-not-allowed | mark that model dead 1 h, try next model; after the list, pick from live `/models` by the vendor's `prefer` regex and remember it |\n| 413 / \"Request too large\" / \"Limit N, Requested M\" | shrink `max_tokens` to fit and retry the same model; an output ceiling (\"OTPM\", \"max_tokens\") is remembered 15 min per model (`caps` in `/health`) |\n| 429 | cool the instance for `Retry-After` (≤15 min) or 60 s |\n| 401 / 403 | cool the instance 1 h |\n| 5xx / timeout (120 s) / network | breaker: 2 strikes → 25 s |\n\nAfter the first pass over every vendor, the router retries up to 2 more rounds — immediately for transient failures, or after waiting for the soonest cooldown when that fits the deadline. With `omni_deadline_ms` set, a vendor that cannot finish in the time left is skipped while a faster one is queued, and `max_tokens` is capped to what the vendor can stream before the deadline (a `finish_reason: \"length\"` reply beats a timeout — the client continues it).\n\nState lives in `omni_state` (SQLite) so it survives isolate recycling. `GET /health` shows what is cooling, dead, resolved, and capped.\n\n## Routes\n\n`GET /health` · `GET /v1/models` · `GET /api/providers` · `GET /api/models?provider=` · `POST /v1/chat/completions` (also `/`, `/chat/completions`) · `POST /api/update {provider, model}` binds a vendor's default · `GET /` matrix UI.\n",[],[810],["D",1777220541701],["D",1789508444194],{"_11":12,"_156":72},{"_11":12,"_152":-5,"_71":72,"_30":70,"_153":154,"_155":24},{"_42":143,"_13":16,"_36":39,"_144":106,"_145":-5,"_146":-5,"_147":-5,"_148":-5,"_149":-5,"_150":14,"_151":12},"ctx",{"_55":-5,"_176":855,"_856":857,"_858":859,"_860":24,"_861":24,"_862":24,"_863":174,"_864":-5,"_865":-7,"_866":-7,"_867":26,"_868":24,"_869":24,"_870":-5,"_871":24,"_872":24,"_873":24,"_874":-5},"ENV",{"_826":827,"_828":829,"_830":16,"_831":832,"_833":834,"_835":836,"_837":838,"_839":840,"_841":842,"_843":844,"_845":846,"_847":848,"_849":850,"_851":852,"_853":854},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
