* test: reproduce issue #898 (Codex fast mode service tier) * fix(codex): add Fast mode (service tier) toggle and /fast command (closes #898) * feat(codex+web): Fast mode UI toggle with full persistence Wires the Codex Fast mode (service tier) end-to-end so it can be toggled from the web composer and survives reload/handoff: - shared: serviceTier on Session/SessionPatch, session-alive payload, resume target, and a SessionServiceTierRequest schema - cli: AgentSessionBase carries serviceTier through keepAlive; runCodex syncs it to the session instance - hub: service_tier column (schema v10 + migration), store setter, sessionCache + syncEngine plumbing, POST /sessions/:id/service-tier - web: api.setServiceTier + mutation, a Fast/Standard toggle in the composer settings (gated to Codex GPT-5.5/5.4), and StatusBar now reflects the real tier instead of the effort heuristic Refs #898 * fix(codex): preserve unset/persisted service tier on startup keepalive Addresses HAPI Bot [Major] on PR #904: applyCurrentConfigToSession ran setServiceTier(currentServiceTier ?? null) on wrapper-ready, collapsing the untouched `undefined` state into explicit Standard. The immediate setCollaborationMode keepalive then persisted serviceTier: null, silently downgrading resumed Fast sessions and disabling account-default Fast. - Seed currentServiceTier from the persisted session (sessionInfo.serviceTier), so a resumed Fast thread keeps running Fast. - Only call setServiceTier when the tier is explicit (!== undefined), preserving the three-state omit semantics at the keepalive boundary. - Add regression tests: persisted Fast is re-asserted; untouched omits the tier. * feat(codex+web): gate Fast toggle on catalog-advertised service tier The Fast toggle was gated on a model-name regex (gpt-5.5/5.4), which still showed a no-op control to API-key users — Fast credits only apply with ChatGPT login. Codex's model/list catalog advertises the service tiers actually available for each model in the current auth/plan context, so gate on that instead: - cli: capture serviceTiers (ids) per model in ModelListItem + normalizeModel - shared: CodexModelSummary.serviceTiers (flows through the existing getSessionCodexModels pass-through; no hub change needed) - web: codexModelAdvertisesFastTier(sessionModel, models) replaces the regex; SessionChat gates the toggle on it (hidden while the catalog is loading/errored). The toggle now only appears when toggling it will actually take effect. Refs #898 * fix(codex): make explicit Standard service tier sticky across resume Addresses HAPI Bot [Major] (round 2): a single persisted null conflated "untouched" with "explicit Standard". A user who turned Fast off persisted null, but startup mapped null -> undefined (untouched) and omitted serviceTier, so an account/thread-default Fast could silently return after restart/resume. Introduce a distinct stored representation: - 'fast' / 'standard' are explicit user choices; null/undefined = untouched. - Translate 'standard' -> Codex app-server serviceTier: null ONLY when building thread/turn params (toAppServerServiceTier); untouched omits the field. - /fast off now stores 'standard'; the web Standard option sends 'standard'. - Tighten SessionServiceTierRequest to enum(['fast','standard']) so stray tier strings are never forwarded. Tests: sticky-Standard-on-resume regression; turn/thread params translate 'standard'->null and omit on untouched; hub route applies fast/standard and rejects unsupported values + local sessions. Refs #898 * fix(codex): recognize real Fast tier (id 'priority', name 'Fast') in catalog gate Live E2E against an authed Codex session revealed the model catalog advertises the Fast tier with id 'priority' and display name 'Fast' (not id 'fast'), so the /fast/i gate — which only saw tier ids — wrongly hid the toggle for valid ChatGPT users on gpt-5.5/gpt-5.4. Capture both the tier id and name as lowercased tokens so the existing name-based match recognizes 'Fast'. The sent value stays 'fast' (the documented service_tier value / raw additionalSpeedTiers request tier). Verified end-to-end: gpt-5.5/gpt-5.4 gate on, gpt-5.4-mini off. Refs #898 * fix(codex): preserve service tier across session resume Resuming a Codex session spawns a fresh session (serviceTier null) and merges the old one in. Unlike model/effort/permissionMode, serviceTier was neither threaded through the resume spawn nor preserved in mergeSessionData, so a resumed Fast (or explicit Standard) session silently reverted to the account default. Thread serviceTier through the spawn path like its siblings: - hub: resumeSession passes session.serviceTier to spawnSession; rpcGateway + syncEngine carry it in the spawn RPC payload; mergeSessionData preserves it old->new (safety net). - cli: SpawnSessionOptions.serviceTier; apiMachine forwards it; buildCliArgs emits --service-tier for codex; the codex command parses it; runCodex seeds currentServiceTier from the spawn override first (opts.serviceTier ?? sessionInfo.serviceTier), so a resumed thread immediately runs the right tier. Verified end-to-end: set Fast -> kill process -> reopen -> resumed session (new id) still runs Fast. Tests: buildCliArgs --service-tier (codex only), runCodex spawn-override seed, mergeSessionData service-tier preservation. Refs #898 * fix(codex): send advertised 'priority' tier id for Fast, not 'fast' The model catalog advertises the Fast tier with request id 'priority' (display name 'Fast'), and OpenAI docs confirm service_tier='fast' maps to the request value 'priority'. The app-server serviceTier override is a raw request value that does not validate unknown strings (a live probe accepted 'bogus-xyz'), so sending 'fast' risks being silently ignored — no Fast applied. Translate the stored 'fast' state to app-server 'priority' at the thread/turn param boundary (toAppServerServiceTier); the stored/UI/command representation stays 'fast'/'standard'. Verified live: a turn with serviceTier='priority' runs and consumes the Fast-tier rate budget. Addresses HAPI Bot [Major]. Refs #898 * fix(codex): validate --service-tier CLI value (fast|standard) Addresses HAPI Bot [Minor]: the internal --service-tier spawn arg accepted any non-empty string, unlike the web /service-tier enum, so a malformed value could be seeded into currentServiceTier and persisted via keepalive. Parse it to 'fast'|'standard' and reject anything else, matching the web endpoint. Refs #898
hapi-web
React Mini App / PWA for monitoring and controlling hapi sessions.
What it does
- Session list with status, pending approvals, todos, and summaries.
- Chat view with streaming updates and message sending.
- Permission approval and denial workflows.
- Permission mode and model selection.
- Machine list and remote session spawn.
- File browser and git status/diff views.
- PWA install prompt and offline banner.
Runtime behavior
- When opened inside Telegram, auth uses Telegram WebApp init data.
- When opened in a normal browser, you can log in with
CLI_API_TOKEN:<namespace>(orCLI_API_TOKENfor the default namespace). - The login screen includes a top-right hub picker; if unset, the app uses the same origin it was loaded from.
- Live updates come from the hub via SSE.

Development
From the repo root:
bun install
bun run dev:web
If testing in Telegram, set:
HAPI_PUBLIC_URLto the public HTTPS URL of the dev server.CORS_ORIGINSto include the dev server origin.
Tests
Unit tests run under vitest + jsdom:
bun run test:web
End-to-end browser tests for the scratchlist component (real Chromium, real
inert focus blocking, real localStorage round-trips) live at the repo root
under e2e/:
bun run test:e2e # headless
bun run test:e2e:ui # Playwright UI mode (debug)
The spec drives a Vite-served fixture page (web/e2e-fixtures/scratchlist-fixture.html)
that mounts the production ScratchlistPanel in isolation, so no hub /
auth / socket setup is required.
Build
bun run build:web
The built assets land in web/dist and are served by hapi-hub. The single executable can embed these assets.
Standalone hosting
You can host web/dist on a static host (GitHub Pages, Cloudflare Pages) and point it at any hapi hub:
- Build the web app. If your static host uses a subpath, set the Vite base:
bun run build:web -- --base /<repo>/
- Deploy
web/distto your static host. - Set hub CORS to allow the static origin (
HAPI_PUBLIC_URLorCORS_ORIGINS). - Open the static site, click the top-right Hub button on the login screen, and enter the hapi hub origin.
Clear the hub override in the same dialog to return to same-origin behavior.
