2026-10-11fix: append browser state to the session only when it changes (#37)Aman Kumar
persistState appended a browser-harness-state entry on every ownership callback, session_tree and shutdown, so the append-only session file and Pi Web's "+N custom" chain grew without bound. A snapshot is now written only when it differs from the last one persisted or restored. Fixes #26 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
2026-08-02refactor: delete exports and knobs that nothing callsamankumarsingh77
isInternalUrl, SPECIAL_KEYS, andThen and mapErr had no callers in src or test. BrowserState.remoteBrowserId was parsed on restore and never written — the field that is actually read lives on DaemonStatus. IpcServer.disconnectClient and IpcServer.clients() were unreachable, as was EventRouter.allClients and a write-only lineCount counter. DAEMON_STALE_SOCKET_CLEANUP was a hardcoded true with an if around it, so the unlink now runs unconditionally. CdpBridge.isAlive and getSessionOwner look equally dead from src/ alone, but test/manual/bridge-test.ts drives both — they are the only seams that suite has, so they stay.

2026-08-02refactor: tidy the whitespace the comment removal left behindamankumarsingh77
Drops leading blank lines where a file header was removed, collapses double blank lines, and closes the empty catch/handler blocks whose only content had been a comment. Whitespace only. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
2026-08-02refactor: strip comment noise from the root modulesamankumarsingh77
Removes install/command banners and comments restating the code. Keeps one-line notes for the per-session profile-pin re-read, the deliberately surviving transport on shutdown, seed-before-attach under a pin, and the starts-with-return wrap rule. src/prompt.ts is untouched.

2026-08-02refactor: close the remaining unguarded type assertionsamankumarsingh77
Types the event-queue iterator's TReturn as undefined so the terminal result needs no cast; declares the isError field the pi runtime reads by duck-typing; binds socket to a local const in the daemon transport; replaces the @ts-ignore on the optional sharp import with a non-literal specifier so src/ still typechecks where sharp was not installed. Adds src/util/guards.ts as the single home for narrowing over unknown — isRecord plus scalar/array readers — and converts the two private isObject copies in cdp/types.ts and daemon/protocol.ts along with every inline `as Record<string, unknown>` in domains/js.ts and domains/render.ts. Gives Accessibility.getFullAXTree a real result schema, closing the last unvalidated CDP boundary: only nodeId is required, every object carries additionalProperties, and each AX value stays Unknown, so the tree decodes as a whole or fails as a whole rather than being filtered. Guards the five tool-result `details` readers, the daemon attach response, the persisted session state, the browser-namespace flag, and the fs errno narrowing, each feeding an already-present failure path. The daemon-transport socket binding is not a bug fix: send() runs synchronously inside sendWithTimeout's promise executor, so socket cannot be reassigned between the check and the write. It removes the assertion and makes the write immune to a later refactor that adds an await. Two assertions survive by design and are documented in the task report: the never->unknown re-widening in util/tool.ts, which the type-erased tool registry makes unavoidable, and the AsyncFunction constructor lookup in domains/js.ts, which JavaScript exposes no typed binding for.

2026-07-22feat: add forms domain and durable window binding (v0.9.0) (#14)Aman Kumar
- Add forms domain with a universal field setter that auto-detects element type and fires framework-compatible input events (React native-setter trick) - Add window-binding helper to capture and bind the real Chrome windowId as the session's durable window identity on every new-window code path - Wire supporting changes across CDP session/ownership, client, navigate, isolated-tab, prompt, and state - Add manual tests for forms and window binding - Bump version 0.8.3 -> 0.9.0 Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
2026-05-05feat: tab ownership — isolate harness tabs from the user's browsingamankumarsingh77
Track which page targets this harness session opened so the agent can never attach to, switch to, or close a tab the user opened themselves. New tabs are spawned in a dedicated Chrome window (newWindow:true on first open, openerId chaining after) so harness activity stays visually separate. - new OwnershipRegistry (src/cdp/ownership.ts) tracks owned targetIds and the harness window seed; mutations notify a single listener that persists to BrowserState (ownedTargetIds, harnessWindowTargetId) - attachFirstPage prefers an already-owned live target; otherwise opens a fresh harness-owned tab in its own window instead of grabbing whatever page the user is on - session subscribes Target.setDiscoverTargets and reaps targetDestroyed events so the registry stays in sync with reality - listTabs returns owned:boolean per tab and reconciles dead ids - browser_list_tabs defaults to scope:"owned"; pass scope:"all" to inspect the user's other tabs (read-only — they cannot be switched to or closed) - browser_switch_tab refuses non-owned tabs, with a clear remediation hint - browser_new_tab opens inside the harness window via openerId, falling back to a fresh window when the seed has been closed - new browser_close_tab tool — owned tabs only, supports unique hex prefix Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
