* 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

Security model
Access is controlled by:
- Telegram initData verification plus bound Telegram users (bound via
CLI_API_TOKEN:<namespace>). CLI_API_TOKENbase secret for CLI and browser access (namespace is appended by clients).
Transport security depends on HTTPS in front of the hub.
Build for deployment
From the repo root:
bun run build:hub
bun run build:web
The hub build output is hub/dist/index.js, and the web assets are in web/dist.
Networking notes
- Telegram Mini Apps require HTTPS and a public URL. If the hub has no public IP, use Cloudflare Tunnel or Tailscale and set
HAPI_PUBLIC_URLto the HTTPS endpoint. - If the web app is hosted on a different origin, set
CORS_ORIGINS(orHAPI_PUBLIC_URL) to include that static host origin.
Standalone web hosting
The web UI can be hosted separately from the hub (for example on GitHub Pages or Cloudflare Pages):
- Build and deploy
web/distfrom the repo root. - Set
CORS_ORIGINS(orHAPI_PUBLIC_URL) to the static host origin. - Open the static site, click the Hub button on the login screen, and enter the hapi hub origin.
Leaving the hub override empty preserves the default same-origin behavior when the hub serves the web assets directly.
