chore(release): cut 0.1.100

* fix(claude): stop probing context usage after turns

Use Claude stream/result usage for parent context tracking, and update the meter from compact boundary post tokens. Subagent usage reports stay out of the parent context meter.

* fix(claude): clear compact context fallback between turns

 Archived subagents disappear from the track, by design.

That same archive shows the subagent leave the track on every connected client.

Model B keeps these distinct: they share everything the directory determines, but nothing the workspace owns. The right-sidebar surfaces split cleanly along this line, and the split is enforced purely by **what each piece of state is keyed by**.

+`diff-pane.tsx` is the canonical wiring site: it passes `{ serverId, cwd }` to the git queries and `{ serverId, workspaceId, cwd }` to the draft/override/attachment scope keys.
+
+**Do not "fix" the sharing away.** Re-keying a directory-backed query by `workspaceId` makes same-`cwd` workspaces diverge (two windows onto the same git tree showing different diffs). Re-keying owned state (drafts, expanded paths) by `cwd` makes them leak between distinct workspaces on the same folder. The `workspaceId`-keyed builders carry a `// workspaceId is opaque; do not parse this key back into a path.` comment — the opaque-id fallback to `cwd` exists only for old payloads without a `workspaceId`, not as a content-sharing mechanism.
+
+One deliberate non-violation: `AgentFileExplorerState.directories`/`files` cache directory listings inside the `workspaceId`-keyed explorer map. Same-`cwd` workspaces therefore keep duplicate caches, but they can never diverge — both fetch the identical directory via `listDirectory(workspaceRoot, …)`. This is duplication, not leakage, and is left as-is.

+## Runtime-only Terminal Sessions
+
+Terminals are live daemon state, not persisted JSON records. A terminal carries a `workspaceId` while it is running; workspace-scoped terminal lists include only terminals with the matching `workspaceId`. Legacy live terminals without an owner remain visible to unscoped terminal reads but contribute to no workspace status.
+
+Terminal activity contributes to the workspace status bucket **per `workspaceId`**: a working terminal drives `running` onto the workspace it carries only. Same-`cwd` siblings are untouched; terminal visibility is likewise `workspaceId`-scoped.

+layout, register `h/[serverId]`; do not register host leaf routes such as
+`h/[serverId]/workspace/[workspaceId]`, `h/[serverId]/open-project`, or
+`h/[serverId]/index` there. The `h/[serverId]/_layout.tsx` file owns those leaf
+routes with its own nested stack and relative screen names:
+`workspace/[workspaceId]/index`, `open-project`, `index`, and so on. Expo Router
+warns with `[Layout children]: No route named ...` when a layout registers
+grandchildren. Treat that warning as a route-tree bug: on native, this shape can
+leave a nested index route mounted without its local dynamic params and render a
+blank screen.
+
+Do not paper over missing required route params by reading global params in the
+leaf. Required dynamic params belong to the matched route. If
+`useLocalSearchParams()` misses one, fix the layout ownership.
+
+Keep non-route modules out of `src/app`. Expo Router treats ordinary `.ts` and
+`.tsx` files there as routes, which produces `missing the required default
+export` warnings and pollutes the route tree. Put shared route policy in
+`src/navigation`, `src/utils`, or another non-route directory.
+
+Treat `/h/[serverId]` as the host home route. It resolves to the last remembered
+workspace for that host after the workspace-selection store hydrates unless the
+host's hydrated workspace list proves that workspace is gone; hosts without a
+remembered workspace go to `open-project`.

 OMP is a built-in Pi-compatible provider, disabled by default. It uses the `omp` command and imports terminal-started sessions from `~/.omp/agent/sessions` when enabled. Other Pi-compatible forks can still be custom providers that extend `pi`, override `command`, and set `params.sessionDir` to their JSONL session directory.
 
+Pi and OMP currently use different RPC names for slash-command discovery. The Pi package accepts `get_commands`; OMP accepts `get_available_commands`. Keep this as an explicit adapter setting for the built-in provider instead of probing with a fallback, because both packages return unknown-command errors without the request `id`, which otherwise turns a fast mismatch into the normal RPC timeout.
+
 Pi RPC extension UI dialog requests (`select`, `input`, `editor`, `confirm`) are bridged into Paseo question permissions and answered with `extension_ui_response`. Pi extensions such as `ask_user` may chain dialogs: for example, a `select` can be followed by an optional-comment `input`. When an `ask_user` tool call declares `allowComment: true`, Paseo presents the selection and optional comment as one question permission, answers Pi's initial `select` immediately, then auto-answers the follow-up optional `input` with the comment the user already supplied (or an empty string). Preserve placeholders and optional/skip semantics for standalone optional inputs so the app can still distinguish "skip this optional input" from "cancel the whole dialog." Fire-and-forget extension UI requests such as notifications are intentionally ignored by the provider adapter unless Paseo grows first-class UI for them.
 
 OpenCode MCP injection is dynamic and session-scoped. Call OpenCode's `mcp.add` endpoint with the MCP server config and do not follow it with `mcp.connect`; `connect` only toggles MCP servers already present in OpenCode's own config. New OpenCode versions return `McpServerNotFoundError`/404 for `connect` after a dynamic add because the server is not config-backed, while older versions silently swallowed the same missing-config path.

+Draft metadata lookups should avoid creating provider sessions when the upstream provider has top-level APIs for that metadata. Prefer `AgentClient.fetchCatalog`, `listCommands`, or `listFeatures` over creating a scratch `AgentSession`; scratch sessions can show up as empty native sessions in provider import/history UIs. `fetchCatalog` is the single discovery API for models and modes — provider implementations may use one process, separate upstream calls, or static data internally, but callers outside the provider do not get separate runtime model/mode probes.
 
 Provider session import has its own contract. The picker calls `listImportableSessions` and receives rows only: provider handle, cwd, title, prompt previews, and last activity. Import calls `importSession({ providerHandleId, cwd })` for the selected row and must not call listing again. The provider returns the resumed session, storage config, persistence handle, and hydrated timeline for that one native session; `AgentManager.importProviderSession` seeds the daemon timeline and publishes the Paseo agent only after it is ready.
 
+## Provider Helper Processes
+
+Provider-owned helper processes that can outlive an individual agent session must be recorded in the daemon's managed-process registry. Store provider/kind metadata, the PID, launch command/args, and process identity captured from the platform process table. Remove the record on normal exit or shutdown.
+
+If a helper process has a readiness phase, the provider's lifecycle model must own the process immediately after `spawn`, before readiness succeeds. Startup timeout, startup exit, and daemon shutdown must all clean up through that owned generation. Do not keep a spawned helper only inside a readiness promise; that creates a live process outside the manager/reaper contract.
+
+Daemon bootstrap reconciles that ledger in the background, without blocking startup: dead PIDs are deleted, PID identity mismatches are deleted without killing anything, only positively matched Paseo-owned leftovers are terminated, and a record whose process cannot be inspected is left in place for the next reconcile rather than deleted. Do not add broad process-name sweepers for provider cleanup; cleanup starts from records Paseo previously wrote.

+Provider plan usage is fetch-on-demand, not a daemon push subscription. The app calls `provider.usage.list.request` through React Query when the usage tooltip or Host Usage settings screen is shown, and the daemon returns the normalized `ProviderUsage` list directly.
+
+To add plan usage for a provider, add `packages/server/src/services/quota-fetcher/providers/<provider>.ts` and register it in `packages/server/src/services/quota-fetcher/manifest.ts`. The provider file exports only its fetcher class; provider auth, endpoint constants, API schemas, and normalization helpers stay private in that file. A fetcher owns provider auth/API parsing and returns the generic shape:
+
+- `providerId`, `displayName`, `status`, and optional `planLabel`
+- any number of `windows` such as Session, Weekly, or Biweekly
+- optional `balances` for credits, USD, requests, or tokens
+- optional `details` for provider-specific rows
+
+Keep the protocol shape provider-agnostic. Do not add provider-specific renderers for new limit windows; labels and generic bars should carry the UI. API responses should be parsed and normalized with Zod inside the fetcher, while the protocol boundary stays strict so old/new client compatibility is explicit.

Two quirks preserved verbatim: schedule/\* is reached via the chat dispatcher's OWN `default` arm (2183), not the top-level `??`; and `start_workspace_script_request` (a workspace type) is special-cased before terminal delegation (2150).

+# Terminal Activity Indicators
+
+Paseo surfaces terminal activity as a tab indicator (the same "running" dot used by agents).
+
+## Current state
+
+Terminal activity is source-agnostic plumbing. `TerminalActivityTracker` holds the current per-terminal state and emits transitions to the manager, worker protocol, websocket subscription, app buckets, dots, and notifications.
+
+The tracker defaults to unknown (`null`). Activity production lives outside terminal stream parsing: agent hook commands report coarse activity to the daemon's local `/api/terminal-activity` endpoint.
+
+## Architecture
+
+```
+TerminalSession
+  ├── TerminalActivityTracker               one per session
+  │     ├── set(state)                      records the latest state
+  │     └── onChange(snapshot, previous)    fires only on resolved-state transitions
+  │
+  └── onActivityChange({ activity, previous })   subscribed in TerminalManager
+        ├── emits terminalsChanged          terminal list/tab indicators only
+        └── subscribeTerminalActivity       per-transition stream for notification policy
+        └── subscribeTerminalWorkspaceContributionChanged  workspace status rollup only
+```
+
+`TerminalActivityTracker` is the single stateful object per session. It holds `{ state, changedAt }`, starts at unknown (`null`), and fires `onChange` only when the state actually changes.
+
+Terminal directory snapshots (`terminalsChanged`) and workspace contribution changes are separate concerns. A title-only change produces a terminal list snapshot but never touches workspace descriptors. A transition that changes the derived workspace bucket (e.g. idle -> working, working -> idle, attention cleared) emits both a terminal list snapshot and a server-internal `TerminalWorkspaceContributionChanged` event, which Session consumes to invalidate every active workspace sharing the owning workspace's `cwd`.
+
+### Transitions carry their own history
+
+Each `onChange` delivers both the new snapshot and the `previous` one (`{ state, changedAt }`). The transition flows unchanged up through `TerminalSession.onActivityChange` (as `{ activity, previous }`), the worker protocol's `terminalActivityChange` event, and the manager-level `subscribeTerminalActivity(listener)` stream (`{ terminalId, name, cwd, activity, previous }`).
+
+The daemon consumes these transitions, not snapshots. When a transition moves from `working` to `idle`, the tracker records finished attention, so the terminal shows the same green finished dot as an idle agent that needs review. The websocket layer also fires a "Terminal finished" attention notification. A terminal that exits while still working emits no turn-end notification.
+
+Terminal list visibility is `workspaceId`-scoped: a terminal belongs to the workspace that created it, and same-`cwd` sibling workspaces do not see it in their terminal lists. Terminal status routing starts from that owning workspace, uses the owning workspace's `cwd`, then fans the status bucket out to every active workspace with the same `cwd`.
+
+Path-prefix routing is only a legacy fallback for unowned terminal activity contribution. If a live terminal has no `workspaceId`, the daemon resolves the deepest active parent workspace from the terminal `cwd`, then fans status out to active same-`cwd` siblings of that owner. That fallback contributes status, but it does not make the terminal visible in workspace-scoped terminal lists.
+
+## Hook reporting
+
+Terminals receive four environment variables when the daemon creates the shell:
+
+- `PASEO_TERMINAL_ID`
+- `PASEO_ACTIVITY_TOKEN`
+- `PASEO_TERMINAL_ACTIVITY_URL`
+- `PASEO_HOOK_CLI` — absolute path to the current `paseo` CLI executable.
+
+The generated shell command uses `PASEO_HOOK_CLI` to run the current CLI. `paseo hooks <agent> <event>` then reads the terminal id, token, and activity URL, asks the agent hook provider registry to resolve the event to a coarse activity state, and silently posts `{ terminalId, token, state }` to the activity URL. Missing env, unsupported agents/events, malformed hook input, and daemon/network failures are no-ops so agent hooks never break the user's terminal session.
+
+Claude hook mapping:
+
+- `UserPromptSubmit` → `running`
+- `Stop`, `StopFailure`, `SessionEnd` → `idle`
+- `Notification` with `reason` or `matcher` equal to `idle_prompt` → `needs-input`
+
+Codex hook mapping:
+
+- `UserPromptSubmit` → `running`
+- `PreToolUse`, `PostToolUse` → `running`
+- `PermissionRequest` → `needs-input`
+- `Stop` → `idle`
+
+OpenCode uses a server plugin instead of command hooks. The plugin listens to OpenCode bus events and emits these Paseo hook events:
+
+- `session.status` with `busy` or `retry` → `running`
+- `session.status` with `idle` → `idle`
+- `permission.asked` → `needs-input`
+- `permission.replied` → `running`
+
+The daemon maps hook states onto terminal activity like an agent lifecycle plus unread attention: `running` → `state: working`, `idle` → `state: idle`, and `needs-input` → `state: idle` with `attentionReason: needs_input`. A `working` → `idle` transition records `state: idle` with `attentionReason: finished` until the user focuses that terminal; plain idle terminals still contribute no workspace status.
+
+## Focus clearing
+
+Client heartbeats include the focused terminal id. When a visible client focuses a terminal with an `attentionReason`, the daemon clears the attention and leaves the terminal idle. Plain idle terminal activity does not contribute to workspace status, so a workspace whose only attention source was that terminal rolls up from `needs_input` or `attention` back to `done`.
+
+### Agent hook installation
+
+Installing hooks edits the user's real agent config files, so it is opt-in. The daemon setting
+`enableTerminalAgentHooks` (persisted under `daemon.enableTerminalAgentHooks`, default `false`)
+gates installation. It is surfaced in the app under a host's **Terminals** settings as "Enable
+terminal agent hooks" — "Get notifications and status from terminal agents. This installs hooks in
+your agent config files." `applyTerminalAgentHookSetting` reconciles the installed hooks with the
+setting: at startup it installs only when enabled; toggling the setting live installs on enable and
+removes Paseo's marker-matched hooks on disable. `paseo hooks` keeps working regardless — the gate
+only controls whether the daemon writes hooks into agent configs, not whether the CLI can post
+activity when the env is present.
+
+When enabled, Paseo installs provider hooks globally:
+
+- Claude hooks are written to `~/.claude/settings.json` (or `CLAUDE_CONFIG_DIR/settings.json` when that override is set).
+- Codex hooks are written to `~/.codex/hooks.json` (or `CODEX_HOME/hooks.json` when that override is set). Codex supports a native `commandWindows`, so each Paseo hook includes both POSIX and Windows commands. Non-managed Codex hooks are trust-gated by Codex; users may see Codex's hook review prompt before the hook runs.
+- OpenCode gets a self-contained plugin at `$XDG_CONFIG_HOME/opencode/plugins/paseo-terminal-activity.js` (or `~/.config/opencode/plugins/paseo-terminal-activity.js` when XDG is unset; `OPENCODE_CONFIG_DIR` still wins when set).
+
+Installation is marker-based/idempotent for config hooks and exact-file/idempotent for the OpenCode plugin. Paseo preserves user hooks, removes only its own marker-matched command hooks, and leaves hooks installed across daemon shutdown. Outside a Paseo terminal they are inert because the command or plugin is gated on `PASEO_TERMINAL_ID`.
+
+Provider variation lives in `AGENT_HOOK_PROVIDERS`: provider id, installed events, config install metadata, and runtime event-to-activity resolution. The daemon calls `installRegisteredAgentHooks()` once; the CLI calls `resolveHookActivity(provider, event, input)`. Adding a provider should add one provider entry and register it in `AGENT_HOOK_PROVIDERS`, without editing the generic CLI command or daemon bootstrap.
+
+The installed hook command keeps the config portable and resolves the CLI at runtime:
+
+```sh
+[ -n "$PASEO_TERMINAL_ID" ] && "${PASEO_HOOK_CLI:-paseo}" hooks claude <event>
+```
+
+Codex also receives the Windows equivalent:
+
+```bat
+if defined PASEO_TERMINAL_ID (if defined PASEO_HOOK_CLI ("%PASEO_HOOK_CLI%" hooks codex <event>) else (paseo hooks codex <event>))
+```
+
+Paseo injects `PASEO_HOOK_CLI` so Codex's hook shell cannot pick up a stale global `paseo` before the current one. The command still falls back to bare `paseo` if the env is missing, and it still no-ops outside Paseo terminals because the `PASEO_TERMINAL_ID` gate remains first. Paseo also prepends the CLI binary directory to each terminal `PATH` as a secondary fallback. All other behavior lives in `paseo hooks`: read the env, map the event, POST activity, and no-op/fail-open when anything is missing or unavailable.
+
+If config installation fails, daemon startup and terminal spawn continue without terminal activity hooks.

+# Terminal performance
+
+How terminal output stays low-latency, what the invariants are, and how to measure before/after any change to the pipeline. Read this before touching anything under `packages/server/src/terminal/` or `packages/app/src/terminal/runtime/`.
+
+## The pipeline
+
+```
+pty (node-pty, forked worker process)
+  → headless xterm parse (worker, snapshot fidelity)
+  → TerminalOutputCoalescer (worker, ≤1 IPC message per 5ms per terminal)
+  → process.send IPC → daemon main process
+  → TerminalOutputCoalescer (per client stream, terminal-session-controller.ts)
+  → binary ws frame (2-byte header + raw bytes)
+  → client decode (daemon-client.ts) → stream router → emulator runtime
+  → xterm.write (back-to-back; xterm batches internally)
+```
+
+Terminal frames share the daemon main event loop with all agent traffic. The `eventLoopDelay` block in the `ws_runtime_metrics` log line (every 30s in `daemon.log`) is the ground truth for "the daemon is busy" — p99/max there directly bound worst-case terminal frame delay.
+
+## Invariants (the easy-to-break ones)
+
+- **Coalescers are leading+trailing throttles.** The first chunk after an idle window flushes immediately (synchronously); only sustained bursts wait for the trailing timer. Reverting to trailing-only adds a full window (~5ms) to every keystroke echo.
+- **Output coalescing happens in the worker, before IPC.** One `process.send` per pty chunk was a main-loop flood under build output. Non-output messages (snapshot/snapshotReady/titleChange/exit) must flush the coalescer first so ordering is preserved.
+- **Coalesced output carries the LAST chunk's revision.** Snapshot replay dedup (`replayTerminalOutputAfterSnapshot`) skips buffered output with `revision <= replayRevision`; a merged batch with a lower revision would be wrongly skipped (lost output).
+- **The input-mode tracker runs once per process boundary, not per hop.** The worker owns the authoritative tracker; the daemon caches the replay preamble from `getTerminalState` responses and `snapshotReady` messages. Do not reintroduce a per-chunk `feed()` on the daemon main loop.
+- **Snapshot catch-up is backpressure-gated.** A stream falls back to a full snapshot only when `outputBytesSinceSnapshot > MAX_TERMINAL_OUTPUT_FRAME_BYTES` (256KB) **and** the client transport reports `bufferedAmount > MAX_CLIENT_BUFFERED_BYTES` (4MB). A client that keeps draining streams continuously, no matter how much output is produced. Before this gate existed, every 256KB of build output dropped a frame and forced a full JSON cell-grid snapshot (~200k objects across IPC) — the historical source of spiky lag and GC hitches.
+- **Client output writes are not serialized per frame.** The emulator runtime drains contiguous plain writes straight into xterm (which buffers internally). Only barrier ops (`clear`, `snapshot`, `suppressInput` writes) wait — behind a zero-length sentinel write — so resets can't interleave with in-flight output.
+
+## Measuring
+
+- **Node-only benchmark (fast iteration, server pipeline):** `npx tsx scripts/benchmark-terminal-latency.ts`. Boots an isolated daemon (fresh `PASEO_HOME`, random port — never 6767), measures echo latency percentiles, burst jitter, and snapshot counts under ramped mock-agent load. Writes JSON to `/tmp/paseo-terminal-bench/`. Healthy numbers (2026-06): echo p50 ~2.3ms, p95 ~3.3ms, a 2MB burst fully streamed with `snap=0`.
+- **Browser perf specs (user-perceived path):** gated behind `PASEO_TERMINAL_PERF_E2E=1` —
+  `packages/app/e2e/terminal-performance.spec.ts` and `packages/app/e2e/terminal-keystroke-stress.spec.ts` (per-stage keydown→xterm-commit breakdown under mock-agent load). Healthy: keydown→commit p50 ~18ms under 600-key burst.
+- **Production:** grep `daemon.log` for `ws_runtime_metrics` and read `eventLoopDelay` + `bufferedAmount`.
+
+## Known remaining contention (follow-up candidates)
+
+- A single large `agent_stream` message (e.g. a 250KB diff payload) measurably delays terminal echo (~100ms-class dips) — cost is split between daemon serialization and app-side parse/render on the shared browser main thread.
+- Relay-attached clients pay pure-JS tweetnacl encryption + base64 per frame on the daemon main loop (`packages/relay/src/encrypted-channel.ts`).
+- `sendToClient` re-stringifies session messages per socket; only matters for multi-socket connections.
