Merge upstream/main into reproduce/issue-1720

Resolve conflicts after 914 upstream commits:
- CHANGELOG.md: keep brew opencode fix entry in Unreleased
- .gitignore: keep superpowers docs exclusion, take upstream additions

Drop /usr/local/ TOOLCHAIN_SEGMENTS addition — /usr/local/bin is part
of the default macOS PATH, so treating it as user-configured would skip
the login-shell fallback that this fix relies on. Upstream tests
(pass 1602) confirm minimal system PATH must not look user-configured.

# Terminal WebSocket Transport Protocol
## Goal
Use a single persistent WebSocket for terminal input and output, while keeping the legacy SSE output route and HTTP input route as compatibility fallbacks.
## Scope
- Primary full-duplex path: WebSocket (`/api/terminal/ws`)
- Legacy output fallback: SSE (`/api/terminal/:sessionId/stream`)
- HTTP input fallback remains: `POST /api/terminal/:sessionId/input`
## Framing
- Text frame:
- client -> server: terminal keystroke payload
- server -> client: raw PTY output chunk
- Binary frame: control envelope
- Byte 0: tag (`0x01` = JSON control)
- Bytes 1..N: UTF-8 JSON payload
## Control Messages
- Bind active socket to terminal session:
- client -> server: `{"t":"b","s":"<sessionId>","v":2}`
- Keepalive ping:
- client -> server: `{"t":"p","v":2}`
- server -> client: `{"t":"po","v":2}`
- Server control responses:
- ready: `{"t":"ok","v":2}`
- bind ok: `{"t":"bok","s":"<sessionId>","runtime":"node|bun","ptyBackend":"...","v":2}`
- exit: `{"t":"x","s":"<sessionId>","exitCode":0,"signal":null}`
- error: `{"t":"e","c":"<code>","f":true|false}`
## Multiplexing Model
- Single shared socket per client runtime.
- Socket has one mutable bound session.
- Client sends a bind control when the active terminal changes.
- Text frames always apply to the currently bound session.
- PTY output is pushed back over the same socket as text frames.
- Client keeps the socket primed so both stream subscription and input reuse the same transport.
## Security
- UI auth session required when UI password is enabled.
- Origin validation enforced for cookie-authenticated browser upgrades.
- Invalid or malformed frames are rate-limited and may close the socket.
## Fallback Behavior
- New clients prefer `capabilities.stream.ws` and reuse the same socket for input.
- If stream WebSocket capability is unavailable, clients fall back to SSE output.
- If terminal input cannot be sent over WebSocket, clients fall back to HTTP input.
- The removed `/api/terminal/input-ws` path should fail with `404 Not Found`.

/**
* Agent memory storage.

* works, what was decided, where things live.
* - **global** — `<userConfigRoot>/memory.json`. Who the user is and how they
* want to be worked with. It belongs to no project, so it cannot live under
* one.
*
* The split is not cosmetic. A wrong project fact costs one project and is
* noticed quickly; a wrong global fact quietly shapes every session in every
* project, and the user has no code to check it against. Global memory is
* therefore deliberately narrower: fewer entries, and only the types that
* genuinely have no other home.
*
* This is NOT the notes surface. Notes are what the user writes for themselves
* and hands to the agent by pinning; memory is what the agent writes for
* itself. Keeping them apart keeps an agent mistake out of the user's notes.
*
* Because the agent writes here unprompted, two invariants guard the store:
*
* - **Restatements replace.** A memory the agent phrases differently the second
* time supersedes the first rather than sitting beside it, so the store
* cannot fill with variants of one fact that later disagree.
* - **Timestamps are the record of change.** The panel derives "new" and

# Managed OpenChamber Agent Tool
## Purpose
This module exposes OpenChamber to agents as typed OpenCode custom tools. There
are two, because controlling sessions and driving a page are separate intents
the user can want independently:
- `openchamber` — projects, sessions, worktrees, and scheduled tasks. Enabled
while the persisted `agentControlToolEnabled` setting is not `false`.
- `openchamber_web` — looking at and interacting with the page in OpenChamber's
browser panel. Enabled while `agentWebToolEnabled` is not `false`.
Both default to on, are toggled in Settings → General → OpenCode CLI, and apply
on the next managed OpenCode restart. Each tool carries only its own actions and
only the parameters those actions use, so turning one off removes its inputs
from the schema rather than leaving them visible. The plugin is injected only
when OpenChamber launches and owns the OpenCode process, and not at all when
both settings are `false`.
- The plugin accepts the action's inputs either inside `parameters` or beside
`action`, because models produce both shapes; an explicit `parameters` object
wins on a conflict. Rejecting the flattened shape turned a call that plainly
carried a `url` into "url is required", which reads as a broken tool rather
than a malformed call.
## Runtime flow
1. The OpenChamber HTTP listener binds and publishes its authoritative port.
2. `prepareManagedOpenCodeEnv()` materializes the plugin under
`<openchamber-data-dir>/agent-tool/` and appends its `file://` URL to
`OPENCODE_CONFIG_CONTENT` without replacing existing plugin entries.
3. A random per-child token and loopback callback URL are added only to the
managed OpenCode child environment.
4. The plugin calls `POST /api/openchamber/agent-tool` with its typed input and
OpenCode's authoritative session directory.
5. The route delegates the fixed action allowlist directly to the shared
OpenChamber control service. The CLI uses the same service through its
authenticated HTTP adapter, so Goal Mode ordering, wait behavior,
partial-failure reporting, and scheduled-task contracts have one owner.
6. Each action definition owns a short presentation title and a separate
agent-facing description. The generated schema uses the description to state
required inputs or one non-obvious behavior, while completed calls use the
short title in native tool metadata.
## Agent context budget
- The tool exposes one shared parameter object rather than repeating parameters
in a large per-action union. Action descriptions carry only required inputs,
defaults, or one non-obvious semantic detail.
- Obvious fields rely on their names and JSON types. Parameter descriptions are
reserved for formats, dependencies, scope, and behavior that cannot be safely
inferred from the field name.
- Session dispatches do not wait by default. Agents are told to set `wait` only
when the user asks or the next step requires the completed result.
- The tool exposes only agent-relevant actions
(`OPENCHAMBER_AGENT_TOOL_ACTIONS`): `schedule.status` stays CLI-only because
`schedule.list` already returns scheduler status, and enable/disable are one
`schedule.toggle` action driven by the `disabled` boolean.
- The tool description frames intent: created sessions and scheduled tasks are
user-facing work the user follows up with, never a channel for the agent to
delegate parts of its own current task.
- Optional behavior switches (`worktree`, `goal`, `agent`, `variant`, `wait`)
state their default and an explicit "only when the user asks" rule so agents
do not invent worktrees, goal mode, or waits the user never requested.
- Detailed combination rules are enforced by the shared control service and
returned as actionable usage errors only after an invalid call. Per-action
examples and a repeated per-action parameter schema are intentionally omitted.
## Security invariants
- The callback accepts loopback requests only and requires the current
per-child bearer token using a timing-safe comparison.
- The token is never persisted, logged, returned to the UI, or written into
the materialized plugin.
- Inputs map to a fixed action and parameter allowlist. There is no arbitrary
CLI, shell, route, or URL forwarding.
- Session/worktree deletion and project-path registration are not exposed.
- An aborted tool request propagates an abort signal into the shared service.
## Result contract
Every completed call returns JSON:
```json
{
"schemaVersion": 1,
"ok": true,
"action": "session.create",
"data": {}
}
```
Command and operational failures use the same envelope with `ok: false` and
an `error` object. OpenCode-level cancellation can still produce a native tool
error state.
## Runtime parity
- Web and Desktop managed OpenCode: injected automatically.
- External OpenCode selected with `OPENCODE_HOST` or skip-start: not injected,
because OpenChamber does not control that process environment.
- VS Code: not injected; the extension owns a separate OpenCode lifecycle.
- Hosted and Capacitor mobile clients use the server's managed OpenCode tool
when connected to such a server; no tool runs in the client runtime.
## The calling tool is part of the request
Each generated tool sends its own name with every callback. Models routinely
drop the namespace their tool's name appears to supply — `openchamber_memory`
asked for `memory.read` gets called as `read` — and resolving the bare name
inside the calling tool's action set makes that unambiguous even where it is not
globally (`delete` belongs to both schedule and memory).
Resolution never reaches outside the tool that asked: `open` from the memory
tool fails rather than driving the browser. An unresolvable action answers with
the actions that tool actually has, because an error that only says
"unsupported" leaves the model to guess a second wrong name — which is exactly
what happened before this existed.

Session dispatches return immediately by default and you receive no notification when a dispatched session finishes, so never promise to report back on it; the user follows it in OpenChamber; a dispatched session needs no follow-up from you. If the user later asks how it went, use session.messages (add wait to block until it is idle, lastAssistant for just the final answer) — session.send always sends a NEW prompt and never just waits. Set wait only when the user asks or the next step requires the completed result. Session and worktree deletion are unavailable.";

Pass a selector to browser.snapshot to read one part of a long page. browser.inspect returns computed styles when the question is how something renders.

Save something only when it will still be true in a later session — a stable preference, a project convention, a decision and its reason, or a hard-won pointer. Do not save one-off task state, anything you can read from the code, secrets or credentials, or anything the user asked you not to keep. Choose the scope deliberately: global is about the user and reaches every project, so put a project's conventions in project scope.

# Browser Control Broker
## Purpose
This module carries agent browser actions from the server to the client that
owns the in-app browser view, and the result back. The browser lives in a
renderer, not in the server process, so the server can never act on a page
itself; it can only ask and wait.
## Boundaries
- `broker.js` owns request lifetime: it publishes one action through the
injected `emitRequest`, holds the pending request, and settles it on a client
result, a timeout, or an abort signal. It knows nothing about transports.
- `routes.js` is the result callback (`POST /api/browser-control/result`). It
validates the envelope and hands the outcome to the broker.
- `../../index.js` supplies `emitRequest`, which writes the request to the
OpenChamber SSE clients and returns how many were reached.
- `../openchamber-control/service.js` is the only caller. It maps the
`browser.*` actions of the `openchamber_web` tool onto `broker.request()` and
owns their parameter validation.
- The client half is `packages/ui/src/lib/browser/controlClient.ts`, which
registers the mounted browser pane as the one responder.
## Invariants
- Capability belongs to the connection, not to configuration. A client declares
it can drive a page by opening its event stream with `browser=1`, which only
a Chromium host does; the flag lives and dies with that connection, so there
is no setting to enable and no restart to remember.
- `emitRequest` counts only clients that can serve the action. `browser.open`
needs any client, because opening a tab is what creates a view; every other
action needs a declared-capable one.
- Exactly one client performs a request. The broadcast reaches everyone who
could serve it, so a client claims the request over
`POST /api/browser-control/claim` and acts only if granted; the first claim
wins and every other client does nothing. Deciding by whose result arrives
first would be too late, because by then each of them has already clicked.
A claim for a settled request is refused for the same reason.
- Nobody listening is answered immediately with a 503 describing the
environment, never by blocking for the full timeout. A blocked wait followed
by a timeout cannot be told apart from a page that hung.
- A client that accepted a request and then disappeared still times out.
Assuming success would report a page interaction that never happened.
- A result for an unknown request id is accepted with `matched: false`, not an
error: a client answering after the timeout has behaved correctly.
- The result route parses its own body. This server has no global body parser,
and a missing one silently turns every answer into an agent-visible timeout.
- Request payload limits are sized for a page snapshot (visible text plus every
interactive element), not for a control message.

/**
* Request/response broker between the agent tool and the in-app browser.
*
* The browser lives in the renderer, not the server, so the server cannot act
* on a page directly. It publishes a request over the existing OpenChamber
* event stream and waits for the client that owns the browser view to post the
* result back.
*
* The request goes to every client that could serve it, because the server
* cannot know which one is showing a page. Exactly one must act on it, so a
* client claims the request before touching anything and only the first claim
* is granted. Without that, two connected desktop clients would both click, and
* the losing one's late result would not undo what it had already done.
*
* Two failure modes matter and are handled explicitly rather than as timeouts:
*
* - No client is listening. The agent is told immediately that the browser is
* not open, instead of blocking for the full timeout and then reporting
* something ambiguous.
* - The client accepted the request and then went away. That still times out,
* because the alternative — assuming success — would be a lie.

# Context Obligatory Messages
Messages explicitly pinned by the user are stored under
`session.metadata.openchamber.context_obligatory_messages` as `{ id, createdAt,
role }`. The UI uses a fresh-read metadata merge when pinning or unpinning.
The server runtime listens for OpenCode's dedicated `session.compacted` event.
It fetches every pinned message by ID, keeps non-empty text parts, sorts them
by the stored creation time, and immediately sends one synthetic user part
through `prompt_async`. OpenCode's session runner serializes this with its own
post-compaction continuation. Missing individual messages are skipped without
discarding the remaining context. Ordinary idle events perform no work and
make no requests.
After a successful send, the runtime merge-writes
`context_obligatory_last_compaction_message_id`. This cursor prevents a
replayed compaction event from reinjecting the same summary. The runtime is
owned by the OpenChamber web backend and therefore is not available in
extension-only VS Code mode.

# Dev Server Tunnel
## Purpose
This module carries raw TCP bytes between a desktop client and a dev server
running on the OpenChamber host, so a remote dev server can be opened in the
browser panel without anything being rewritten.
The page is served from a real origin at the root of its own host. That is the
whole design: absolute URLs resolve, cookies scope correctly, HMR sockets
connect, and developer tools behave as they do locally. No HTML, header, or
URL is inspected or modified, which is what the previous rewriting proxy did
and what made it fragile per framework.
## Boundaries
- `runtime.js` is the host end: it accepts the WebSocket upgrade at
`/api/dev-tunnel`, authenticates it, opens a TCP socket to the requested
local port, and pipes the two together.
- `client.js` is the local end: it binds a loopback listener on the user's
machine and pipes each accepted connection through one WebSocket. It lives in
this package because it needs a WebSocket client the package already depends
on; the desktop shell drives it over IPC.
- Port discovery is not owned here. `runtime.js` is given the reachable set by
the same dev-server discovery the user's own list is built from.
- The browser panel decides when to tunnel; this module never chooses a target.
`packages/ui/src/lib/browser/devTunnel.ts` owns that decision, including for
navigations the page starts itself: a tunnelled page that sends the view to
another loopback port means a port on the host, not on the user's machine.
## Invariants
- The reachable set is exactly what dev-server discovery offers the user, never
"any loopback port". Without that restriction an authenticated client could
dial arbitrary local services on the host — databases, admin panels, the
OpenCode API — through this socket.
- Authentication depends on whether the caller is a browser, and this is
deliberate rather than a relaxation:
- With an `Origin` header the request came from a browser context, and the
usual origin allowlist applies unchanged. That check is a CSRF defence: a
hostile page can make a browser open a WebSocket carrying ambient cookies,
and the origin is what exposes it.
- With no `Origin` the request must carry client-token auth. A browser cannot
reach this path — the WebSocket API always sends an origin and never lets a
page set an `Authorization` header — so this case is the desktop shell.
- Concurrency is capped per host, not per page, because one page load opens
many sockets.
- A connection that cannot be established fails the socket rather than holding
it open; a stalled connect is bounded by an explicit timeout, and so is the
WebSocket handshake. While it is pending the local socket is paused and its
buffered bytes are capped, so a local process writing into a stalled
handshake cannot grow the desktop app's memory.
- A tunnel that cannot be opened is reported to the panel, never replaced by the
plain loopback URL. On a remote instance that substitution would change which
machine answers and show local content under a remote address.
- Closing either end closes the other. A half-open pipe would leave the page
waiting on bytes that will never arrive.

# Dictation module
Server-authoritative streaming speech-to-text for the chat composer, plus
local text-to-speech. The client streams 16 kHz mono PCM16 chunks (base64)
over a WebSocket; the server runs the transcription and streams live partial
transcripts back.
Local TTS (Kokoro via sherpa-onnx OfflineTts) runs in the same worker process
and is exposed as `POST /api/dictation/tts/speak` (JSON `{text, speakerId?,
speed?, model?}` → WAV bytes; 503 with `reasonCode` while the model is
downloading). TTS models live in the same catalog/downloader as STT models
(`local/model-catalog.js` `LOCAL_TTS_MODEL_CATALOG`) and are managed by the
same status/download/delete routes.
## Ownership
- `runtime.js` — registers `GET /api/dictation/status`,
`POST /api/dictation/models/:modelId/download`, and the
`/api/dictation/ws` WebSocket endpoint (auth-gated the same way as the
terminal WS: UI session token or `oc_url_token`, plus origin check).
Created from the startup pipeline (`startup-pipeline-runtime.js`) before
the generic OpenCode proxy so routes are not shadowed.
- `stream-manager.js``DictationStreamManager`, one per WS connection.
Chunk reordering by `seq` + ack, resampling to the provider rate,
auto-commit every ~15 s of audio, silence suppression by PCM peak,
partial-transcript concatenation, adaptive finalization timeout.
- `service.js` — provider resolution and readiness. Providers:
- `local` (default): sherpa-onnx Parakeet TDT in a forked worker process.
Models auto-download in the background on first use; while missing, the
stream fails with `reasonCode: 'model_download_in_progress'` and the
status route reports per-model install/download state.
- `openai-compatible`: buffered per-segment transcription against any
OpenAI-compatible `/v1/audio/transcriptions` endpoint
(`openai-compatible-session.js`, reuses `../tts/stt.js`).
- `local/` — worker process + client (IPC, idle shutdown TTL), sherpa
recognizer engine and realtime session (throttled re-decode for partials),
model catalog and downloader. The native `sherpa-onnx-node` addon is only
ever loaded inside the worker process.
- `audio.js` — PCM16 helpers: format parsing, peak, WAV wrapping, streaming
linear resampler.
## WebSocket protocol (JSON text frames)
Client → server: `start {dictationId, format, options}`,
`chunk {dictationId, seq, audio}`, `finish {dictationId, finalSeq}`,
`cancel {dictationId}`, `ping`.
Server → client: `ready`, `ack {ackSeq}`, `partial {text}`,
`finish_accepted {timeoutMs}`, `final {text}`,
`error {error, retryable, reasonCode?}`, `pong`.
`options` in `start` carries the client-selected provider config:
`{ provider: 'local' | 'openai-compatible', language?, localModel?,
openaiCompatible?: { baseUrl, model, apiKey } }`.
## Invariants
- Never load `sherpa-onnx-node` in the main server process.
- The stream manager acks only the highest contiguous seq; the client is
expected to retain unacked segments for retry/replay.
- Silence-only segments (peak < 300) are cleared, never committed, so
Whisper-style providers do not hallucinate on silence.
- Model files live under `~/.config/openchamber/speech-models`.

- The global hub keeps a bounded replay buffer keyed by SSE `eventId` so reconnecting browser clients can receive buffered events after their requested `Last-Event-ID`.
- Directory WS clients still attach one upstream `/event?directory=...` SSE reader per connection because directory streams are scoped.
- If an upstream SSE stream stalls after the browser WS is already ready, the reader aborts that upstream fetch and reconnects upstream with `Last-Event-ID`, keeping the browser WS alive when recovery is fast.
- When the shared global upstream reconnects after it was previously ready, the global WS bridge sends a fresh `ready` frame to already-ready browser clients. The browser treats this as a reconnect edge and can run scoped state repair without requiring the browser WS to close.
- Health checks are reserved for initial upstream connect failures and explicit upstream-unavailable responses, not for ordinary stall recovery on an already-established stream.
- Global synthetic events such as `openchamber:session-status`, `openchamber:session-activity`, `openchamber:notification`, and `openchamber:heartbeat` are preserved on the WS path, but heartbeat frames are emitted only while an upstream SSE stream is actively attached.
- Global UI broadcasts are fan-out capable across both SSE and WS clients.

## Notes for contributors
- Keep filesystem policy (workspace root checks, error mapping, exec timeout behavior) inside this module, not in the composition root.
- Filesystem `EPERM`/`EACCES` failures use the stable `reason: "os-permission"` response marker. Policy denials such as workspace-boundary or missing-grant failures must not use that marker because a native folder picker cannot remediate them.
- Read-only routes authorize the requested path against the workspace before resolving symlinks. A symlink reached through the workspace may therefore target a file outside it, while a directly requested outside path still requires an exact-path grant. Write routes keep canonical-target boundary checks.
- If adding new `/api/fs/*` endpoints, add them in `routes.js` and extend this document.
- `GET /api/fs/list` may resolve symlinks with `realpath` to read directory contents, but the response `path` and each entry `path` must stay in the caller's requested path space (`path.join(requestedPath, name)`). Returning real paths breaks file-tree expansion for directories reached through workspace symlinks.
- `POST /api/fs/upload` accepts one `application/octet-stream` body with `path` and optional `overwrite=true` query parameters. The body streams into a same-directory temp file with a 100 MiB default cap configurable through `OPENCHAMBER_FS_UPLOAD_MAX_BYTES`; failed and oversized uploads clean up that temp file. New files commit through an atomic no-replace link, existing files return `409` unless overwrite is explicit, directory targets are rejected, and the destination parent resolves before writing so uploads cannot escape through workspace symlinks.

### Status and Diff Operations
- `getStatus(directory)`: Get comprehensive Git status including current branch, tracking, ahead/behind, file changes, diff stats, merge/rebase state.
- `getDiff(directory, { path, staged, contextLines })`: Get diff output for files or entire working tree.
- `getRangeDiff(directory, { base, head, path, contextLines })`: Get diff between two refs.
- `getDiff(directory, { path, staged, contextLines })`: Get diff output for files or entire working tree. Untracked symbolic links are represented as link entries without following their targets.
- `getRangeDiff(directory, { base, head, path, contextLines })`: Get diff between two refs. Uses three-dot `base...head` semantics, so work merged into `head` from `base` is excluded and only the branch's own changes are returned. Prefers `origin/<base>` when that remote-tracking ref exists, so a stale local base branch does not resurface already-merged commits. Exposed as `GET /api/git/range-diff` (`path` optional; omit it for the whole range).
- `getRangeFiles(directory, { base, head })`: Get list of changed files between two refs.
- `getFileDiff(directory, { path, staged })`: Get original and modified file contents for a single file (handles images as data URLs).
- `getFileDiff(directory, { path, staged })`: Get original and modified file contents for a single file (handles images as data URLs and symbolic links as their link-target text).
- `listUntrackedPaths(directory)`: List individual untracked file paths honoring ignore rules. Much cheaper than `getStatus` when that is all a caller needs. Deliberately not `--directory`: collapsed directory entries end in a slash and are rejected by the per-file diff helpers, so a caller would silently lose every file inside a new directory.
- `getUntrackedDiffs(directory, filePaths, { concurrency, contextLines })`: Diffs for untracked files against an empty tree. Resolves the repository context once instead of per file (`getDiff` re-resolves every call, costing an extra `rev-parse` each time) and bounds how many diff processes run at once. Returns one entry per input path in order; unreadable paths yield `''` rather than failing the batch.
- `collectDiffs(directory, files)`: Collect diff output for multiple files.
- `revertFile(directory, filePath, options)`: Revert a file. Default scope `all` discards staged and working-tree changes; scope `working` discards only unstaged/working-tree changes.
- `stageFile(directory, filePath)`: Add one file path to the index.
@@ -46,10 +48,18 @@ The following functions are exported and used by the web server:
### Worktree Operations
- `getWorktrees(directory)`: List all git worktrees for a repository.
- `validateWorktreeCreate(directory, input)`: Validate worktree creation parameters (mode, branchName, startRef, upstream config).
- `createWorktree(directory, input)`: Create a new worktree (supports 'new' and 'existing' modes, upstream setup).
- `createWorktree(directory, input)`: Create a new worktree (supports 'new' and 'existing' modes, upstream setup). After populating the worktree, the repository's `post-checkout` hook runs once with git's standard arguments (null ref as previous HEAD, the checked-out HEAD, and flag `1`) from the worktree directory, mirroring `git worktree add` without `--no-checkout`; a missing or non-executable hook is skipped and a failing hook is logged as a warning, never failing worktree creation or the session bootstrap.
- `removeWorktree(directory, input)`: Remove a worktree (optionally delete local branch).
- `isLinkedWorktree(directory)`: Check if directory is a linked worktree (not primary).
### Worktree creation from a GitHub pull request
The UI provisions `pr-<owner>` via `ensureRemoteName`/`ensureRemoteUrl`
(HTTPS clone URL preferred over SSH) and checks out
`remotes/pr-<owner>/<head>`. A missing head URL or unreachable fork fails with
a clear error before a worktree is kept. If upstream fetch fails during
bootstrap, tracking is left unset rather than writing `branch.*.remote` /
`branch.*.merge` for a ref that was never fetched.
### Commit and Remote Operations
- `commit(directory, message, options)`: Create a commit from the current index. `options.stageFiles` may be provided with `options.files` by older callers to stage only selected unstaged rows before committing, but the shared Git panel now stages/unstages explicitly before commit.
- `pull(directory, options)`: Pull changes from remote.

- `resolveCandidateDirectory(...)`: Generate unique worktree directory candidates.
- `resolveBranchForExistingMode(...)`: Resolve branch for existing-mode worktree creation.
- `applyUpstreamConfiguration(...)`: Set upstream tracking for new branches.
- `runPostCheckoutHook(directory)`: Invoke the worktree's `post-checkout` hook after population, because `git worktree add --no-checkout` and the bootstrap's `git reset --hard` never run git hooks. Runs with git's standard arguments and the worktree as cwd; skips missing/non-executable hooks and never throws on hook failure.

## Response Contracts
@@ -109,6 +120,15 @@ The following functions are internal helpers used by exported functions:
- `mergeInProgress`: Object with `{ head, message }` if merge in progress.
- `rebaseInProgress`: Object with `{ headName, onto }` if rebase in progress.
### Branches Response
- `all`: Local branches plus remote-tracking branches that still exist on their remote. A remote that fails to answer keeps its branches in the list: "we could not ask" must not be reported as "these branches are gone", because callers use this list to decide whether a base branch exists at all.
- `current`: Current branch name.
- `branches`: Per-branch detail keyed by branch name, as reported by `git branch`.
- `defaultBranches`: Each remote's default branch, keyed by remote name. Read from the local `remotes/<name>/HEAD` symbolic ref; for a remote that has none — clone writes it, a hand-added remote may not — the remote itself is asked once with `ls-remote --symref`. A remote that answers neither is absent rather than guessed, and consumers fall back to conventional branch names. Omitted entirely by runtimes that do not provide this Git metadata.

- `GET /api/git/range-diff` is served by the OpenChamber web server, so it is available to web, desktop, and mobile clients. The shared `GitAPI.getGitRangeDiff` is therefore optional: web supplies the HTTP implementation, and VS Code does not implement it because the extension host serves Git through its own bridge rather than these routes. Features built on range diffs (currently the AI diff walkthrough) are not offered in VS Code.
### Staged and unstaged change handling
- `status.files` exposes both `index` and `working_dir` codes. Shared UI uses these as separate scopes: staged rows are derived from non-empty `index` statuses, while unstaged rows are derived from `working_dir` statuses and untracked files.
- A file with both staged and unstaged changes can appear in both UI sections. Staged rows request diffs with `staged: true`; unstaged rows request normal working-tree diffs.

- `path`: Absolute path to worktree directory.
- `directoryCreated`: Present when create returned after the target directory exists while background Git/bootstrap work continues.
- `bootstrapStatus`: Background setup status, with `pending`, `ready`, or `failed`.
- `bootstrapStatus`: Background setup state. The legacy `status` remains `pending`, `ready`, or `failed`, while `phase` reports `directory-created`, `git-ready`, or `setup-ready`. Fast create starts at `pending`/`directory-created`; population and upstream Git completion advances to `pending`/`git-ready` before setup/start scripts; completed setup is `ready`/`setup-ready`. A missing in-memory state falls back to `ready`/`setup-ready`; clients continue to accept legacy status responses that omit `phase`.
- Fast-create background failures remove OpenCode sandbox metadata for directories that never became Git worktrees, and remove the pre-created directory only if it is still empty. User-created files are never recursively deleted by this cleanup.
- Worktree removal waits for any active create/bootstrap task for that directory before deleting it, preventing a background Git or setup task from restoring removed state or racing filesystem cleanup.
- Worktree bootstrap retries transient `index.lock` conflicts. If the lock remains byte-for-byte and metadata-identical across the retry window, it is treated as stale, removed, and population continues automatically; changing locks are left untouched and reported as failures.
- Worktree population enables Git `core.longpaths` (local repo config plus `-c core.longpaths=true` on `git reset --hard`) so deeply nested checkouts under the managed data-dir worktree root do not fail on Windows MAX_PATH with "Filename too long". Path-component limits that the filesystem itself rejects still fail bootstrap, with a clearer path-length guidance message.

- SSH_AUTH_SOCK is automatically resolved via `resolveSshAuthSock` (checks GPG agent, gpgconf).
### Working directory (simple-git)
- Repository operations always pass an explicit `baseDir` (the opened project/directory path) into simple-git. Omitting `baseDir` would default to `process.cwd()`, which breaks when the server was launched from a neutral directory (e.g. `$HOME`) while the opened project lives elsewhere.
- Global identity reads use the user home directory as `baseDir` (they do not need a repository).
- A `GitError` / non-repository result from status or check must not abort project/session enumeration: routes return a soft non-repo payload and log a warning.
### Worktree Naming
- Worktree names are slugified via `slugWorktreeName`.
- Random names use adjectives/nouns from `OPENCODE_ADJECTIVES` and `OPENCODE_NOUNS` lists.

- It resolves those remotes into GitHub repos.
- It expands each repo through `parent` and `source` so PRs in upstream repos can still be found.

- It first searches for **open** PRs by likely source owner plus exact head branch.
- If that fails, it falls back to broader GitHub search for open PRs on the branch name.
- An **open PR from any candidate repo always wins** over a closed/merged one, so a merged fork PR can never hide an open upstream PR for the same head.
- Only when no target has an open PR does it return the branch's newest closed/merged PR, as history.
- History is looked up **only for the ranked-first remote and the branch's own name** — the repo it actually pushes to. Live status is worth searching the whole fork network for; history is not, and asking every target for it multiplies serial GitHub calls until the route hits its `12s` resolve timeout and returns no status at all.
- The history answer is remembered per repo+branch so discovery polls do not re-query it: a found closed/merged record for `6h`, and "no history yet" for `10m`. A found record only changes if a second PR appears on the same head, and while that one is open the open-PR path wins without ever reading this cache.
- Creating, merging, or closing a PR invalidates both the shared repo pull list and that remembered history.
- The route skips the checks summary and the merge-permission lookup for a closed/merged PR: neither is actionable, and both cost extra GitHub calls.
- `403` and `404` during repo lookups are treated as expected gaps, not hard errors.

- Open PR with pending checks -> refresh about every `1m`.
- Open PR with non-pending checks -> refresh about every `5m`.
- Open PR without a stable checks signal -> refresh about every `2m`.
- Closed or merged PR -> stop regular polling.
- Closed or merged PR -> discovery refresh every `5m` (do not permanently stop polling).
- Hidden tab -> skip polling.
- Non-forced refreshes use a `90s` TTL.
- Failed non-forced attempts also observe the `90s` TTL so transient server or rate-limit failures cannot retry on every sidebar update. Forced user/action refreshes bypass this guard.
## Persistence notes for terminal PRs
- Closed/merged branch associations are persisted like open ones, so a reload still shows that the branch's PR was merged.
- Hydrate resets `lastDiscoveryPollAt` for them, so restored history revalidates on the first watcher tick instead of waiting out a discovery interval.

# Markdown Image Grants
## Purpose
This module lets the Markdown image gallery display images that an assistant
explicitly referenced from OpenCode's temporary directory when the UI is on a
different machine.
## Contract
- Chat Markdown rendering is independent: assistant image syntax renders as an
icon and filename, while the gallery only reads finalized Markdown to collect
image candidates.
- `POST /api/openchamber/sessions/:sessionId/markdown-image-grants` prepares up to 12
local images in one message-level request. The server fetches the assistant
message once and verifies every exact image source before reading files.
- Authorization recognizes the same common inline and reference-style image
destinations collected by the UI, including balanced parentheses, while
excluding fenced and inline code.
- Relative and workspace-contained absolute paths resolve against the active
directory. Other absolute paths are accepted only inside
`os.tmpdir()/opencode` after `realpath` resolution.
- PNG, JPEG, GIF, and WebP files are signature-checked and limited to 10 MiB.
- Prepare requests inspect only file metadata and signatures. Workspace images
reuse the existing authenticated `/api/fs/raw` asset route directly. Images
under `os.tmpdir()/opencode` receive the existing path-bound `raw`
`outsideFileGrant`; this module does not add another asset lifetime, copy, or
storage layer. Missing files return per-source results so the gallery can
remove only those items.
The routes are OpenChamber-owned and must be registered before the generic
OpenCode proxy. Web, Electron, hosted mobile, and Capacitor use the shared
server implementation. VS Code does not call this route for workspace images;
those use its local filesystem bridge. If called, the grant route returns an
explicit unsupported response because OpenCode temporary images are not
supported there.

# APNs remote push — signed relay mode
Native iOS background push (notifications even when the app is **suspended or killed**) is
delivered via APNs through a **central relay**, so no user configures an Apple key. Each server
signs its relay requests with an auto-generated keypair, and tokens are bound to the server that
registered them — so a leaked device token alone can't be used to push.
## How it works
1. The app registers its APNs device token with **its own server** (`POST /api/push/apns-token`,
`useNativePushRegistration`). PWA/desktop never register — only the native Capacitor app.
2. The server **binds the token on the relay**: it POSTs `{ token, publicKeyJwk, ts, sig }` to
`POST /v1/push/register-token`, signed with its auto-generated ECDSA P-256 key
(`getOrCreateRelayKeypair`, persisted in settings like the VAPID keys). The relay records
`token → serverId` where `serverId = SHA-256(publicKey)`.
3. On a trigger (ready/error/question/permission), the server composes **generic, content-free**
text — a fixed scenario title ("Agent response is ready" / "Agent needs your input" / "Agent
needs permission" / "Agent hit an error") + the **session name** as the body, no model/project/
message content — plus a **`badge`** count (see below) — and POSTs `{ tokens, title, body,
badge, env, data:{sessionId}, publicKeyJwk, ts, sig }` to `POST /v1/push/send`
(`apns-runtime.js``sendViaRelay`). It does **not** gate on UI visibility (see below).
4. The **relay** (`openchamber-website/apps/api`, Cloudflare Worker) verifies the signature +
`ts` freshness, derives `serverId`, and only delivers to tokens bound to that server. It holds
the single project APNs `.p8` key, signs an ES256 JWT with `crypto.subtle`, and sends each
token to APNs over HTTP/2, returning per-token results; the server drops tokens flagged `drop`
(410 / BadDeviceToken). The relay stores no secret — only `token → serverId` hashes.
5. Tapping a push deep-links to its session via the forwarded `sessionId`.
## Foreground suppression
APNs is **not** gated on UI visibility. A backgrounded WKWebView can't reliably report "hidden"
before iOS suspends it, so a server-side visibility gate dropped background push for short
responses. Instead the server always sends, and **iOS** suppresses the foreground banner
(`PushNotifications.presentationOptions: []` in `capacitor.config`) — so there is no notification
while the app is active, with no race. APNs is the native app's **only** channel; local
notifications were removed (a WKWebView can't tell foreground from background — `document.hasFocus()`
is unreliable — so they leaked while the app was open). Cloudflare is touched only when a native
app with notifications on has a registered token and a trigger fires.
## App-icon badge
Each push carries an **absolute** `aps.badge` = the number of **distinct collapse-ids (`tag`)
pushed since the app was last foregrounded**. It mirrors the lock-screen banner stack.
The count is a `Set<tag>` (`pendingPushTags`) in the trigger runtime (`runtime.js`):
`toApnsGenericPayload` adds the push `tag` and returns the set size as the badge. We key by **`tag`,
not sessionId**, because the tag *is* the banner identity — iOS uses it as `apns-collapse-id`, so
same-tag pushes replace one banner while different tags are distinct banners. One session can raise
several banners (`ready-<id>`, `question-<id>`, `permission-<requestKey>` are different tags), so
counting sessionIds both over- and under-counts the stack; counting tags matches it.
It is deliberately **not** derived from the live attention snapshot (`needsAttention`/`isViewed`):
that machinery drives in-app indicators on *connected* clients, where a backgrounded client stays
"viewing" and `needsAttention` is set by a separate `session.status` event that races the push
trigger. The set self-clears via `clearPendingPushBadge` on any signal that the user is engaging
with the app: the visibility beacon (`updateUiVisibility` wrapper, `visible:true`), **plus** opening
a session (`POST /api/sessions/:id/view`) and sending a message (`POST /api/sessions/:id/
message-sent`). The latter two need no auth and fire reliably on the native app when it foregrounds,
so they are the dependable reset — the visibility beacon alone proved unreliable in WKWebView. This
mirrors the device zeroing its icon badge on `sceneDidBecomeActive` (`AppDelegate.swift`), keeping
server and device in sync.
The value flows `runtime.js` (`toApnsGenericPayload`) → `apns-runtime.js` (`sendViaRelay` body /
direct-mode `aps.badge`) → relay (`pushSendSchema.badge``aps.badge`). It is **not** signed (like
`body`/`data`); the relay still only delivers to bound tokens. The set is server-global, so every
device token of a server sees the same badge.
## Modes
- **Relay (default):** server has no Apple key; `OPENCHAMBER_PUSH_RELAY_URL` defaults to
`https://api.openchamber.dev/v1/push/send` (register URL is derived as `…/register-token`).
- **Direct (fallback):** set `OPENCHAMBER_PUSH_RELAY_DISABLED=true` + `OPENCHAMBER_APNS_KEY_ID/
TEAM_ID/P8` to sign+send from the server itself (HTTP/2 + ES256 JWT); no relay binding needed.
## Config
Server (`apns-runtime.js`):
- `OPENCHAMBER_PUSH_RELAY_URL` (default the public relay), `OPENCHAMBER_APNS_ENVIRONMENT`
(optional override forcing every send to `sandbox` or `production`; normally unset — each
token is delivered to the environment it registered with: the iOS shell reads the
`aps-environment` entitlement from the embedded provisioning profile and reports it at
registration, so Xcode dev builds go to sandbox and TestFlight/App Store to production).
The signing keypair is auto-generated — nothing to set.
- Direct fallback: `OPENCHAMBER_APNS_KEY_ID`, `OPENCHAMBER_APNS_TEAM_ID`, `OPENCHAMBER_APNS_P8`
(or `_P8_PATH`), `OPENCHAMBER_APNS_BUNDLE_ID`, `OPENCHAMBER_PUSH_RELAY_DISABLED=true`.
Relay (Cloudflare Worker secrets via `wrangler secret put` / GitHub Actions): `APNS_P8`,
`APNS_KEY_ID`, `APNS_TEAM_ID`, optional `APNS_BUNDLE_ID` / `APNS_DEFAULT_ENV`. The `push_tokens`
binding table is created by `migrations/0002_push_tokens.sql` (applied on deploy).
## Apple setup (one-time)
1. Apple **Keys** (not Certificates) → create an **APNs Auth Key** (`.p8`) → Key ID + Team ID;
enable **Push Notifications** on App ID `com.openchamber.app`.
2. In the **openchamber-website** repo → Actions secrets: `APNS_P8` (PEM), `APNS_KEY_ID`,
`APNS_TEAM_ID`. Push to `main` → relay deploys, secrets sync, D1 migrations apply.
3. Xcode: confirm the Push Notifications capability; Clean Build Folder; run on device.
## Security posture
- The device token is a per-install secret, but no longer the *only* defence: every relay request
is signed by the server's private key, and the relay only delivers to a token from its bound
`serverId`. A leaked token alone is useless — an attacker has neither the private key nor a
matching binding.
- `serverId` self-certifies (`SHA-256(publicKey)`), so the relay holds no secret; a D1 leak
exposes only `token → serverId` hashes. The signed `ts` (±5 min window) blocks replay.
- Residual: trust-on-first-bind (whoever registers a token first owns it) — acceptable, since
registering already requires possessing the token. Cloudflare rate limiting is defence-in-depth.
## Data confidentiality (what the relay / Apple can see)
The push payload is **not** application-encrypted, so there is no decryption step. The text is
sent in plaintext, protected only by **TLS in transit** (HTTPS to the relay, TLS from the relay
to APNs). The request **signature is authentication, not encryption** — the relay *verifies* it
(valid / invalid), it does not hide anything.
Who can read the alert text:
- **Network hops:** nothing (TLS).
- **The relay (Cloudflare):** the generic title + body (session name), the device token, and
`sessionId`. It stores only `token → serverId` hashes (no text, no payload).
- **Apple APNs:** the alert text too — APNs always reads the alert payload of an `alert` push.
- **The device:** displays it.
This is acceptable **because the text is deliberately content-free**: a fixed scenario title +
the session name only — no model, project, or message content (`runtime.js`
`toApnsGenericPayload`). The session name is the single semi-personal field that crosses the
relay/Apple. To hide even that from Apple would require an end-to-end **encrypted payload**
(`mutable-content` + a Notification Service Extension that decrypts on-device with a key never
sent to the relay) — not implemented, and unnecessary for generic text.
## Android (FCM) note
The Android equivalent is **FCM** (not implemented): the same relay would forward to FCM with a
server key, and the client would register an FCM token (same store/routes + signing).

# OpenChamber Control Service
## Purpose
This module owns the typed control contract shared by the OpenChamber CLI and
the managed OpenCode `openchamber` tool. Both adapters delegate to
`createOpenChamberControlService()`; neither adapter may call or spawn the
other.
## Boundaries
- `service.js` validates and executes the fixed project, model, session, and
scheduled-task action allowlist. `actions.js` marks CLI-only actions with
`agentExposed: false` (currently `schedule.status`); the agent tool consumes
the filtered `OPENCHAMBER_AGENT_TOOL_*` exports. `schedule.toggle` requires
the `disabled` boolean and replaces separate enable/disable actions;
`schedule.list` also returns scheduler status as `scheduler`.
- `routes.js` is the authenticated CLI HTTP adapter. It forwards one action,
preserves service status and partial-result details, and propagates request
cancellation.
- `../agent-tool/runtime.js` is the managed-tool adapter. It wraps service
results in the versioned native-tool envelope and uses a separate ephemeral
loopback credential.
- `../openchamber-sessions/routes.js` and `../scheduled-tasks/service.js` own
their domain operations and are composed into this service.
## Invariants
- Session status and messages come from official directory-scoped OpenCode
APIs. Message output includes only ordered `text` parts.
- Wait never treats an initial idle response as completion after dispatch. It
requires observed activity or a newly completed assistant message.
- Timeout and cancellation are failures, never authoritative idle results.
- Validation that protects side effects runs before session creation or
dispatch. An explicitly requested model, agent, or variant is checked against
the directory's own OpenCode agent and provider lists before any session,
worktree, or goal is created, because `prompt_async` accepts an unusable
selection and then fails only on the event stream. A failed or empty lookup
never turns a valid selection into a rejection.
- `promptDispatched` reports an observed dispatch, never an accepted request.
After `prompt_async` the service confirms a new user message reached the
session; when it does not, the result reports `promptDispatched: false` with
`promptError` instead of claiming success.
- Send and fork dispatches without an explicit model/agent/variant reuse the
target session's last user-message selection before falling back to the
configured defaults; only session creation resolves defaults directly.
- Usage errors name the missing or conflicting input so CLI and agent-tool
callers can correct an invalid request without an upfront usage manual.
- Explicit `projectId` or `directory` scope takes precedence over the managed
tool's current-session directory fallback; the fallback never creates a
conflicting second scope.
- One failed directory status lookup produces `unknown` for only that
directory and does not erase other session results.
- Destructive session/worktree deletion and project-path registration are not
part of the action contract.
- `browser.capture` writes its image on the server, into
`.openchamber/screenshots/` under the scoped project directory, and returns
the project-relative path rather than the image bytes. The client that took
the picture may be on a different machine than the repository, and a path is
what an answer, a commit, or a review can use; base64 in a tool result cannot
be any of those. The agent's label is reduced to a filename fragment, never
used as a path. The result also states how to present the image, because chat
renders the image paths written in a finished answer below that message —
saving the file is not what shows it to anyone.
