	1	+# PolyLLM 1.0 — "AI operating system" upgrade (2026-09-11)
	2	+
	3	+Massive product/UX/UI/mobile-first upgrade of www.polyllm.io. Goal: a premium, app-like multi-model workspace
	4	+("One interface. Every model.") that feels native on iPhone/Android and excellent on desktop, without breaking any
	5	+existing backend behaviour (auth, encrypted keys, chat history, Arena, presets, usage, exports, folders, attachments).
	6	+
	7	+This document is the shared contract between the parallel workstreams. Read it fully before touching code.
	8	+
	9	+## Ground rules (all workstreams)
	10	+
	11	+1. Do not break existing functionality. Reuse services in `src/lib/*`; extend, don't rewrite. Provider quirks stay in
	12	+ `src/lib/ai/providers/*`; components only see `PolyModel` capabilities (see `CLAUDE.md`).
	13	+2. Ownership. Edit only the files/dirs listed for your workstream (plus new files you create there). If you need a change
	14	+ in someone else's file, add a small adapter in your own area and leave a `// TODO(integration: <area>)` comment, or
	15	+ put the request in `docs/upgrade-notes/<your-area>.md`. Exception: `src/lib/client/types.ts` — append-only.
	16	+3. Schema. Tables for the upgrade live in `src/db/schema-workspace.ts` (already migrated: `drizzle/0001_workspace_upgrade.sql`).
	17	+ If you need more columns/tables: append to `schema-workspace.ts` (or create `src/db/schema-<area>.ts`, re-export it in
	18	+ `src/db/index.ts`), then run `pnpm db:generate --name <area>` and `pnpm db:migrate` locally. Never edit existing
	19	+ migration files. Never drop/rename columns.
	20	+4. No dev server in this phase. Multiple `next dev` in the same tree conflict on `.next`. Validate with
	21	+ `pnpm typecheck`, `pnpm lint`, `pnpm test` (vitest) and, for server logic, small vitest units in `tests/unit`. Visual QA
	22	+ happens in the integration phase against a single dev server.
	23	+5. No fake functionality. Every button works or is explicitly labelled "Coming soon" (use `<ComingSoon />` badge from
	24	+ `components/ui/misc` — add it if missing). No placeholder handlers.
	25	+6. Mobile first. Design for 375 / 390 / 393 / 430 px widths first, then tablet, then desktop. Rules:
	26	+ - Phones: bottom sheets instead of centered modals (`ResponsiveDialog`, `BottomSheet`, `ActionSheet` in `components/ui/sheet.tsx`),
	27	+ long-press for message/row actions (`useLongPress`), swipe carousels (`.snap-row` + `useSnapCarousel`), 44 px touch
	28	+ targets (`.tap` helper or explicit min-h), 16 px inputs, `100dvh`/`.h-app`, safe areas (`pb-safe`, `pt-safe`, `--sab`).
	29	+ - Never `window.prompt/confirm/alert` — use `PromptDialog` / `ConfirmDialog` (`components/common`).
	30	+ - No desktop tables overflowing on phones: use stacked rows/cards below `md`, tables from `md` up.
	31	+ - No horizontal overflow, no clipped text, no fixed element blocking content. Respect `prefers-reduced-motion`.
	32	+ - Hover-only controls must also be reachable on touch (`.hover-reveal` shows them on coarse pointers).
	33	+7. Design language (`src/app/globals.css` tokens): neutral warm graphite palette, iris accent, fewer borders, spatial
	34	+ grouping (`.panel`, hairlines) over boxed cards, restrained 150–300 ms motion, `text-balance` headlines, tabular numbers
	35	+ for metrics. Use `Segmented`/`ChipRow` (`components/ui/segmented.tsx`) for filters. Icons: lucide only.
	36	+8. Performance. No new heavy dependencies without a note in your area doc (allowed if < ~40 KB gz and clearly justified —
	37	+ e.g. `katex` for LaTeX). Virtualize long lists (`@tanstack/react-virtual` is installed). Memoize streaming renders.
	38	+9. Accessibility. Labels/aria on icon buttons, focus-visible, keyboard nav for lists/palettes, semantic elements.
	39	+10. Commit nothing. The integrator commits. Leave the tree compiling (`pnpm typecheck && pnpm lint` green) when you finish.
	40	+11. Final report. End with: files created/changed, new API routes (method, path, body → response), anything left as
	41	+ "Coming soon", and QA notes (what to check visually) in `docs/upgrade-notes/<area>.md`.
	42	+
	43	+## Shared primitives (already implemented — use them)
	44	+
	45	+\| What \| Where \| Notes \|
	46	+\| --- \| --- \| --- \|
	47	+\| Tokens, utilities \| `src/app/globals.css` \| `.h-app`, `.pb-nav`, `.pb-safe`, `.tap`, `.hover-reveal`, `.snap-row`, `.panel`, `.glass-strong`, `.mask-x`, `.marquee`, `coarse:`/`fine:` variants \|
	48	+\| Hooks \| `src/lib/client/hooks.ts` \| `useIsMobile`, `useIsTablet`, `useIsCoarsePointer`, `useMounted`, `useKeyboardInset`, `useLongPress`, `useSwipe`, `useLocalStorage`, `useDebounced`, `useCopy`, `useSnapCarousel`, `useStandalone` \|
	49	+\| Sheets \| `src/components/ui/sheet.tsx` \| `BottomSheet` (handle, snap `content\|half\|full`, swipe-dismiss), `ResponsiveDialog` (sheet on phone, dialog/panel on desktop), `ActionSheet` (iOS-style list) \|
	50	+\| Segmented / chips \| `src/components/ui/segmented.tsx` \| `Segmented`, `ChipRow` \|
	51	+\| Dialog replacements \| `src/components/common/prompt-dialog.tsx`, `confirm-dialog.tsx` \| \|
	52	+\| Shell \| `src/components/app/shell.tsx`, `bottom-nav.tsx`, `sidebar.tsx`, `store.tsx` \| Mobile bottom nav (Chat/Arena/Models/Usage/Account), drawer with edge-swipe, keyboard inset. Store adds `labels`, `setLabel`, `activeProjectId`, `searchOpen`, `AUTO_MODEL_KEY`. \|
	53	+\| Token/cost estimator \| `src/lib/client/tokens.ts` \| `estimateTextTokens`, `estimateAttachmentTokens`, `estimateContext`, `estimateCost`, `formatEstimate`, `COST_CONFIRM_THRESHOLD_USD` \|
	54	+\| Smart router \| `src/lib/client/router.ts` \| `analyzePrompt`, `routeModels`, `explainRoute`, `ROUTER_MODES` (pure, transparent) \|
	55	+\| Brand \| `src/components/brand/logo.tsx`, `public/icon.svg`, `public/og.png`, `scripts/brand-assets.sh`, `src/app/manifest.ts` \| "Prism P" mark; `Wordmark` \|

	57	+\| Cross-area stubs \| `components/projects/sidebar-section.tsx`, `components/library/file-library-picker.tsx` \| Baselines; the Projects workstream owns/finishes them. Chat imports `FileLibraryPicker` from that path. \|
	58	+
	59	+## Workstreams & ownership
	60	+
	61	+### A — Chat & composer (`components/chat/` except `model-selector.tsx`, `model-config.tsx`, `model-badges.tsx`; `components/markdown/`; `app/app/chat/`; `lib/chat/`; `app/api/chat/`; `app/api/attachments/`)
	62	+Mobile composer (+ sheet: upload image/document, camera, paste, from library, tools, web search, structured output, system
	63	+prompt, temporary chat), auto-grow 1→6 lines, voice dictation (Web Speech API where available, hidden otherwise), active model
	64	+pill above composer (opens the model picker via `ModelSelector` — keep its public props), attachments (drag/drop, paste,
	65	+camera, chips, multiple), context indicator (`43K / 200K`, warnings at 80/95 %), cost estimate + confirm above
	66	+`COST_CONFIRM_THRESHOLD_USD` with one-tap model alternatives, Smart Router AUTO mode (`selectedModelKey === AUTO_MODEL_KEY` →
	67	+recommendation card before sending: Use / Choose another / Always auto-route), temporary chat (server: `ephemeral: true` in
	68	+`chatRequestSchema` → stream without persisting; badge "Not stored in history"), message toolbar (desktop hover / mobile
	69	+long-press ActionSheet: copy, retry, edit, branch, compare, change model from here, save as prompt, export, rate, more),
	70	+expandable message metadata (model, provider, tokens, cost, TTFT, tok/s, reasoning level), deprecated-model warning with
	71	+replacement suggestion, humanized provider errors with Retry / Switch model / Details, streaming performance (memoized
	72	+blocks, stable markdown, code block Copy/Download/Wrap/Expand, LaTeX via `katex` + `rehype-katex` allowed), inline
	73	+Compare with… (2–4 models; desktop side-by-side, mobile swipeable panels with sticky tabs; reuse `/api/arena` +
	74	+`/api/arena/stream` to run, store as Arena session, "Continue with this model"), empty state with quick actions
	75	+(Write / Code / Research / Analyze a file / Compare models), project instructions applied when `activeProjectId` is set
	76	+(fetch `/api/projects/:id` — Projects workstream provides it; degrade gracefully if 404).
	77	+
	78	+### B — Models (`components/chat/model-selector.tsx`, `model-config.tsx`, `model-badges.tsx`; `app/app/models/`; new `app/(marketing)/models/`, `app/(marketing)/compare/`; `components/models/`; `lib/ai/registry/` (additive); `app/api/models/` (additive); `components/presets/`, `app/app/presets/`; `lib/models/*`)
	79	+Model picker redesign (bottom sheet on phones; desktop dialog), fast search with intent parsing ("cheap vision model",
	80	+"1M context", "under $1/M", "fastest gemini", "json schema"), sections (Favorites, Recent, Recommended, Fast, Best
	81	+reasoning, Cheapest, Largest context, Vision, Coding, Open source, New), compact metadata rows, star favorites, custom labels
	82	+(`store.setLabel`), AUTO entry (Smart Router) with mode selector, model badges (NEW/FAST/CHEAP/REASONING/VISION/CODING/LONG
	83	+CONTEXT), lifecycle badges (New/Active/Deprecated/Retiring/Unavailable), model profile sheet (all fields; show "—" for
	84	+unknown — never invent release dates or cutoffs), `/app/models` catalog (sortable, filters, mobile stacked rows, select →
	85	+Compare), public `/models` and `/compare/[slug]` (`gpt-5.5-vs-claude-sonnet-5`) pages with SEO metadata reading the registry
	86	+server-side (no auth), capability-aware settings grouped Generation / Reasoning / Output / Tools / Advanced with Reset and
	87	+Save preset (presets apply across compatible models).
	88	+
	89	+### C — Arena (`components/arena/`; `app/app/arena/`; `lib/arena/`; `app/api/arena/`; new `app/share/arena/*`)
	90	+Up to 4 models: desktop adaptive 2×2 / side-by-side, phone one panel at a time (`.snap-row`, sticky model tabs, swipe),
	91	+live metrics (status, TTFT, tok/s, in/out tokens, cost), votes (Best / Most accurate / Best writing / Best coding / Best value
	92	+/ Fastest + custom criteria) stored in `arena_votes`, Arena Winner summary with comparative metrics, Blind Arena (Model A/B/C
	93	+until vote; reveal), history, personal scoreboard `/app/arena/scoreboard` (win rate per model, filters Coding/Research/
	94	+Writing/Reasoning/Cost efficiency), exports (Markdown/JSON incl. models, parameters, metrics, ratings), public share of an
	95	+Arena comparison (`shared_arena_sessions`, `/share/arena/[id]`, revoke).
	96	+
	97	+### D — Projects, prompt library, context library (`components/projects/`, `components/library/`, `components/prompts/`; `app/app/projects/`, `app/app/library/`, `app/app/prompts/`; `lib/projects/`, `lib/library/`, `lib/prompts/`; `app/api/projects/`, `app/api/library/`, `app/api/prompts/`)
	98	+Projects CRUD (`/api/projects`, `/api/projects/[id]` returning `{ project, conversations, files, prompts }`), project page
	99	+(instructions, preferred models, notes, files, conversations), `activeProjectId` selector, conversations filtered by project
	100	+(add `projectId` to `ListFilter`/PATCH in `lib/conversations/service.ts` — small additive change allowed), file library
	101	+(`/api/library/files` GET/POST/DELETE with `estimatedTokens`, `/api/library/files/attach` POST `{fileIds}` → `{attachments}`
	102	+copying into `message_attachments`), prompt library with `{{variables}}` (parse, defaults, fill-in sheet before insert into
	103	+composer via `?prompt=` / `router.push('/app/chat?promptId=…')` and a `usePromptInsert` event on `window`), folders/tags/
	104	+favorites, keep existing `prompt_presets`/`model_presets` pages working (migrate the `/app/prompts` page to the new library
	105	+while still listing legacy presets). Finish the two stubs listed above.
	106	+
	107	+### E — Usage analytics, providers, custom endpoints (`components/usage/`; `app/app/usage/`; `lib/usage/`; `app/api/usage/`; `app/app/settings/`; `components/providers/`; `lib/providers/`; `app/api/providers/`; new `lib/ai/providers/custom/`, `app/api/endpoints/`)
	108	+Usage dashboard (KPIs: requests, tokens, cost, avg TTFT, tok/s, avg context, error rate; charts: cost/tokens/requests over
	109	+time, cost by provider/model, requests by model, latency by model; filters Today/7d/30d/90d/Custom + provider/model/project;
	110	+projections "Estimated monthly cost"; savings opportunities computed from real usage_records + pricing; mobile: stacked
	111	+KPI tiles, chart cards full-width, tables → rows). Follow `dataviz` skill guidance (palette from tokens, accessible).
	112	+Provider management redesign (status Connected/Not connected/Validation failed, last validated, models available, Test
	113	+connection with latency, key rotation, remove), extensible provider list. Custom OpenAI-compatible endpoints (Ollama, LM
	114	+Studio, vLLM, llama.cpp, MLX…): `custom_endpoints` table exists; implement adapter via `createOpenAICompatAdapter` with
	115	+per-endpoint baseURL/headers, discovery (`GET {baseUrl}/models`) or manual models, models keyed `custom/<endpointId>:<modelId>`
	116	+surfaced in `/api/models`, chat routing in `lib/chat/service.ts` resolution (coordinate via a `resolveCustomEndpoint()`
	117	+helper you export; document the one-line hook needed in the chat service in your notes if you can't wire it without
	118	+editing A's files — the integrator will wire it). Add `"custom"` to `PROVIDER_IDS` only if every switch over providers stays
	119	+exhaustive-safe (grep first). Settings pages mobile-first (full-screen sections, bottom sheets).
	120	+
	121	+### F — Marketing, onboarding, auth, PWA polish (`components/marketing/`; `app/(marketing)/` except `models`/`compare`; `app/(auth)/`; `components/app/onboarding.tsx`; `app/app/onboarding/`; `app/sitemap.ts`; `public/*` (additive))
	122	+Homepage redesign: hero "One interface. / Every model." + sub-line (Bring your own keys. Compare models. Control every
	123	+parameter. Track every token.), CTAs "Start using PolyLLM" / "Try Arena", animated real product UI in the hero (no abstract
	124	+art), live model strip (public `GET /api/public/models` summary — create it; marquee with provider marks, context, price,
	125	+status), interactive demo switchable Chat/Arena/Models/Usage with simulated streaming and a phone-shaped mobile demo that
	126	+mirrors the real mobile UI, features, security page `/security` (Browser → PolyLLM encrypted server layer → Provider; key
	127	+lifecycle; AES-256-GCM, Argon2id, HttpOnly cookies, CSP, rate limits, audit logs — technically accurate only, verify in code),
	128	+FAQ, footer with contact@spboucher.ai · Simon-Pierre Boucher · Hosted on MacLustr (www.maclustr.io), `/contact` optional.
	129	+Onboarding 6 steps (account → providers → first key → validate → favorite models → first prompt; skippable; progress;
	130	+swipeable on phone) as a full page `/app/onboarding` + first-run redirect logic in `components/app/onboarding.tsx` (keep the
	131	+existing `Onboarding` export working). Auth pages polish (mobile-first). Keep all metadata/OG (already set in `app/layout.tsx`).
	132	+
	133	+### G — Search, command palette, share/export (`components/app/command-palette.tsx`; new `components/search/`; `app/api/search/`; `lib/search/`; `app/share/[id]/`; `lib/conversations/service.ts` export/share functions (additive); `app/api/conversations/[id]/actions/route.ts` (additive))
	134	+Full-text search API with filter syntax `model:claude project:research after:2026-08-01 before: provider: role:` over titles
	135	++ message content (Postgres `ilike`/`to_tsvector` — add a GIN index via a new migration if you use tsvector), grouped results,
	136	+snippets with highlights; search UI: desktop inside ⌘K (search mode), phone full-screen sheet (`store.searchOpen`); universal
	137	+command palette (New chat, Search, Switch model, Open Arena/Usage/Providers/Project, Upload file, Toggle theme, New temporary
	138	+chat (`/app/chat?temporary=1`), Copy conversation URL, keyboard-first). Share: options Entire conversation / Selected messages
	139	+(`messageIds`) with privacy warning sheet, revoke, list of active links in Settings → Data; share page redesign (mobile-first,
	140	+brand). Export: Markdown, TXT, JSON, PDF (print-optimized route `/share/print/[id]` + `window.print()` is acceptable — label it
	141	+"PDF (print)").
	142	+
	143	+## Navigation architecture
	144	+
	145	+- Desktop: sidebar (New chat, Search, Chat/Arena/Models/Prompts/Presets/Library/Usage, Projects, Pinned, Folders, Recent,
	146	+ account menu). Collapsible ⌘B.
	147	+- Phone: bottom nav Chat / Arena / Models / Usage / Account; drawer (hamburger or edge-swipe) for conversations, projects,
	148	+ search; page headers use a compact 48 px bar with a hamburger on the left (`setSidebarOpen(true)`).
	149	+- Every app page must reserve space for the bottom nav (the shell adds `padding-bottom`; pages use `h-full min-h-0 flex-col`
	150	+ layouts and scroll inside, never the document).
	151	+
	152	+## Integration phase (integrator)
	153	+
	154	+1. Wire cross-area hooks (custom endpoint resolution in chat service, project instructions, prompt insert).
	155	+2. `pnpm typecheck && pnpm lint && pnpm test`, `pnpm build`.
	156	+3. Single dev server → Playwright QA at 375×812, 390×844, 393×852, 430×932 + desktop 1440 for every screen listed in the brief
	157	+ (login, signup, onboarding, chat, composer+keyboard, attachments, model switcher, Arena + swipe, drawer, search, projects,
	158	+ catalog, usage, providers, account, sheets). Fix overflow/clipping/tap targets.
	159	+4. Migration on prod via mld hook (`pnpm db:migrate`), deploy `mld stage . polyllm && mld deploy polyllm --node M3U96a`.
