Maybe they're checking if I can infer the intent behind a vague message.\\n\\nI should consider possible scenarios. Are they testing if I can ask clarifying questions? Or maybe they want to see if I can generate a response without more context. Since the message is short, I need to respond in a way that invites them to provide more details. \\n\\nI should acknowledge their greeting and then ask what specific aspect of inference they're testing. That way, I can tailor my response to their actual needs. Also, making sure the tone is friendly and helpful is important. Let me check if there's any other nuance I might be missing. Maybe they're a developer testing the model's capabilities?

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",[394],"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",[402],"f7c3665a-ef01-4a0b-a6b6-dfb1dd469a40","inference-provider.ts","f5b23648-43b6-11f1-91e9-42b51c65c3df",1597,["D",1789451486226],57,"// Instance = catalog row × key slot (KEY, KEY1…KEY9 → name#n). keyEnv null ⇒ keyless.\nimport type { Row } from \"./db.ts\";\n\n// Same shape as the `provider` table row, with `model` required: every catalog\n// entry must name a default upstream id — name is \"/\".\nexport type ProviderSpec = Omit, \"model\"> & { model: string; tags?: string[]; paid?: boolean };\n\nexport type ProviderInstance = ProviderSpec & {\n vendor: string;\n slot: number;\n key: string | null;\n keyIssue: string | null; // non-null ⇒ the secret's VALUE is malformed (see keyIssue()); surfaced on /health and in the catalog\n fallbackModel: string;\n};\n\nconst KEY_SLOTS = 10;\n\n// Secret-value sanity.
