* feat(pi): complete RPC interaction parity * feat(pi): integrate native conversation history * fix(pi): harden RPC lifecycle boundaries * fix(pi): address review lifecycle and upload boundaries * fix(pi): release history transaction on rollback deadline * fix(pi): isolate preflight and timed-out mutations * fix(pi): preserve retry and editor boundaries * fix(pi): disable unavailable history synchronization * fix(pi): gate fallback readiness on history baseline * fix(pi): bind uploads and retire extension requests * fix(pi): preserve canceled and legacy stream boundaries * fix(pi): preserve native fork runtime state * fix(pi): persist dialogs and preserve select values * fix(pi): keep upload authorization path-stable * feat(pi): preserve native steer semantics Route ordinary sends during an active Pi main turn through native steer while keeping explicit queue delivery on the existing composer gestures. Persist the delivery contract across Hub replay and Web retries, and guard stale steer dispatch with streaming generations and ordered prompt fallback. * fix(pi): queue deferred steer deliveries Keep native steer only for the initial live emit. Reconnect replay, CLI backfill, clear-gate release, and mature delivery now downgrade turn-scoped steer intent to the durable HAPI queue without mutating stored provenance. * fix(pi): retain abort guard through preflight miss Treat an immediate no-active abort rejection as a possible async-preflight race. Keep the existing abort boundary alive so a late agent_start receives the compensating abort before queued work is released. * fix(pi): queue stale steer retries A failed send no longer reuses turn-scoped steer intent after its original Pi generation is lost. Text restoration, attachment retry, and legacy retry provenance all enter the durable HAPI queue while fresh ordinary sends retain native steer behavior. * fix(pi): invalidate rejected abort generation After a no-active preflight abort waits through late-start compensation, mark the target stream idle while the runtime mutation lease is still held. Waiting native steers therefore fall back instead of entering the aborted generation. * fix(pi): queue idempotent steer retries Track whether a localId insert created a new row. Initial inserts may retain live Pi steer, while duplicate-localId retries deliver a queue-safe view of the stored row without overwriting its original provenance. * fix(pi): sync command-only history before fallback Read the Pi append log before retiring a successful prompt that produced no agent lifecycle. Preserve FIFO history associations across missing entry events, and fail the wrapper closed if that mandatory synchronization cannot be completed.
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.

Authentication
See src/hooks/useAuth.ts and src/hooks/useAuthSource.ts.
- Telegram Mini App: Uses initData from WebApp SDK.
- Browser: Uses CLI_API_TOKEN from login prompt.
- JWT tokens with auto-refresh.
Data fetching
See src/hooks/queries/ for query hooks and src/hooks/mutations/ for mutations.
- Sessions, messages, machines via TanStack Query.
- Git status and file operations.
- Optimistic updates for message sending.
Real-time updates
See src/hooks/useSSE.ts.
- SSE connection to
/api/events. - Session/message/machine update events.
- Automatic cache invalidation on events.

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.
