perf(app): row-grained replica cache persistence (#3755 )

* feat(hub): guide starter setup (#3651) * feat(hub): guide setup with provider IDs * fix(hub): preserve login setup state * feat(hub): select starter agent runtime Use the connected daemon's provider snapshot so generated Hub bundles only contain complete provider, model, and mode combinations. * fix(hub): stage starter runtime choices Keep providers with valid modes selectable when the daemon has no default mode, so users explicitly choose the complete runtime. * fix(hub): scope runtime choices to workspace Provider capabilities can vary by repository, so request the snapshot for the bundle directory that guided setup will deploy. * fix(server): stop short start gates from undercutting provider startup budgets (#3621) * fix(server): stop short start gates from undercutting provider startup budgets Agent creation still failed on contended cold starts after #3578, because two shorter gates on the same path fire before the event-stream readiness budget can apply. A traced creation reached session.create twelve seconds in, past the 10s session.create gate, and the agent was then killed by a bare "timeout" at fifteen seconds from AGENT_RUN_START_TIMEOUT_MS while the SSE connect was still running. A run-start bound of 15s wraps a path that is deliberately allowed 30s, so the outer gate always wins and the inner budget is unreachable. Give session.create the shared OPENCODE_SERVER_STARTUP_TIMEOUT_MS budget, since creating the first session for a directory is part of OpenCode coming up, and derive its error message from the constant instead of hardcoding "10s". Raise AGENT_RUN_START_TIMEOUT_MS to 60s with a comment recording that it must stay above the slowest provider startup budget; it stays a literal because that module is provider-agnostic. Related to #3571. * test(server): drive the run start budget through a real AgentManager The run start boundary tests replaced AgentManager.waitForAgentRunStart with a bare timer, so they never exercised the production run-state transition or the agent_state subscription the real wait depends on. That path could regress while the tests stayed green. Build the scenario on a real AgentManager with a provider session that holds its turn start open for a configurable span, so pendingRun.started, the lifecycle change to "running", and the agent_state notification are what the wait actually observes. Budgets stay independent literals and the settled-before/after assertions are unchanged. * fix(server): describe agent run start timeouts --------- Co-authored-by: Mohamed Boudra <boudra.moha@gmail.com> * fix(relay): validate handshake keys (#3669) * fix(files): keep large source previews responsive (#3665) Large read-only files bypassed the editor's virtualization and eagerly mounted every highlighted token, which could stall the renderer for seconds and consume gigabytes of memory. Route source previews through bounded platform renderers and reject reads above their display budgets before accumulation. * fix(hub): make guided setup choices actionable (#3677) Show a concise login success state, scope starter choices to available Hub connections, wait for daemon capabilities, and avoid partial starter bundles when setup cannot proceed. * Keep released agent SDK versions reproducible (#3678) Pin the validated provider and protocol SDK dependency pair so fresh installs cannot silently float after a Paseo release. Refresh the Nix npm dependency hash for the resulting lockfile. * feat(app): refine agent profile creation (#3680) Keep profiles as the richer primitive while restoring the familiar star cue and clearer guidance for agent selection. Account for borders in shared field geometry so controls preserve their declared heights across form consumers. * fix(app): restore native composer auto-growth (#3681) Native multiline inputs were always scrollable, which kept iOS content-size measurement pinned to one line. Keep native sizing intrinsic below the cap and enable internal scrolling only after the composer reaches it. * docs(hub): document zero-friction onboarding (#3657) Lead with the browser-to-CLI onboarding journey, document the generated starter bundle, and align guided setup with available Hub connections and daemon-reported runtime defaults. * Surface workspace changes from agent panes (#3682) * feat(app): refine workspace pane actions Prioritize Changes when available, keep Files useful before a selection, and reserve desktop diff clicks for selection so comments require the explicit affordance. Move the Changes shortcut to Shift+G to avoid consuming a likely copy variant. * feat(app): improve access to workspace changes * Expand workspace panel actions and keyboard navigation (#3685) * fix(app): keep file navigation in place Retargeting a File tab allocated a new tab identity, causing the tab track to unmount and remount during navigation. Preserve the identity for File-to-File changes while retaining new instances for cross-kind replacements. * feat(app): expand workspace panel actions Keep the Command Center aligned with workspace tab and pane primitives. Add explicit panel placement, focused open behavior, keyboard navigation for empty panes, and a Changes pill that toggles the visible Side panel without closing its tab. * Restore compact and stable chat timelines (#3716) Restore compact message and footer spacing, reserve independent composer-pill clearance for transcript content and floating controls, and keep visible web tool-call expansion from shifting the reading position. * perf(app): defer replica persistence until user inactivity Whole-replica capture and serialization blocked the JS thread during navigation and streaming. Defer that work until the user has been inactive while allowing long-running streams to persist without becoming the idle signal. * Give every pane a browser-style New tab (#3715) * feat(app): replace empty panes with New tabs Give every retained pane an independently identified New tab, replace it in place when a destination is chosen, and preserve split close and move invariants. Keep existing workspace startup and compact explorer routing explicit, with focused unit and browser regression coverage. * test(app): count content tabs in subagent integration * fix(app): preserve workspace shortcut ownership * fix(app): keep compact model options scrollable The compact model sheet had no sheet-aware scroll owner when profiles filled its viewport, leaving the controls below them unreachable. Keep the root provider view inside Gorhom's scroll container so native sheet gestures work on both platforms. * fix(app): order new tab launcher actions by workflow * fix(app): show the New agent shortcut The command center resolved New agent through the New tab binding, so it advertised Cmd+T despite creating an agent. Resolve the target-agent binding instead and cover the mapping. * fix(app): prioritize side panel launcher actions Lead with supporting workspace tools when the launcher is in the Side panel, while ordinary panes continue to lead with agent creation. * fix(app): align terminal profiles header * docs: add 0.5.0-beta.5 changelog * test(app): align new tab launcher expectations * chore(release): cut 0.5.0-beta.5 * fix: update lockfile signatures and Nix hash [skip ci] * fix(app): make compact git actions menu-only Keep compact toolbars narrow and require users to choose potentially consequential Git and workspace actions from the menu. * fix(app): keep pinned project actions reachable (#3722) * fix(app): keep pinned project actions reachable Preserve an empty project shell after its final workspace is hoisted into the pinned section so project-scoped workspace creation remains available. Co-authored-by: Agent Op <agentop718@gmail.com> * test(app): verify pinned project workspace context --------- Co-authored-by: Agent Op <agentop718@gmail.com> Co-authored-by: Mohamed Boudra <boudra.moha@gmail.com> * fix(app): stop a string SVG transform from crashing the app (#3711) * fix(app): stop a string SVG transform from crashing the app A root <Svg> is a real React Native view, so react-native-svg rewrites a *string* `transform` into RN style syntax in `extractTransformSvgView`, using a PEG parser whose grammar only accepts SVG transform functions. Upstream lets that parser's SyntaxError escape, so any string it does not understand takes the whole app down during render: SyntaxError: Expected transform functions but "n" found. "found": "n", "location": { "start": { "offset": 0 } } `none` reproduces that message character for character; so does any other CSS value (`rotate(-90deg)`, `translate(10px, 0)`). Every sibling extractor in that file already catches the same error and degrades, so the asymmetry is the bug: a string that is merely ignored on a <Path> crashes on an <Svg>. We feed that path untrusted input. The daemon scans a project for favicon.svg / icon.svg / logo.svg (packages/server/src/utils/project-icon.ts) and ships it to the client, where ProjectIconImage hands it to SvgCss. Running the library's own XML parser over `<svg style="transform:none">` yields exactly `transform: "none"` on the root, which is why the crash starts once a host connects and the project icons render, with no terminal involved. Note this is *not* reachable from an RN-style array transform: the extractor returns arrays untouched and only parses strings, so `style={{ transform: [{ rotate: "-90deg" }] }}` (the context window meter and the checks ring) was never a factor. Patch the three builds a consumer can resolve - Metro takes the package's `react-native` field (src/*.ts), Node and Vitest take main/module - and register react-native-svg with the postinstall patch runner so the patch actually applies. The new test pins all three. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EDwfsMWoSFfPm2cFXe5noQ * test(app): cover parsed root SVG transforms Exercise the dependency patch with root props produced by the library's XML and CSS parsers, including embedded style rules that can arrive through project icons. Keep dependency-patch documentation focused on the reusable install and resolution constraints. --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Mohamed Boudra <boudra.moha@gmail.com> * fix(pairing): warn that pairing links grant daemon access (#3734) A pairing offer remains valid across daemon restarts, so remove the incorrect rotation guidance and warn users where the durable credential is displayed. * fix(app): preserve timeline retry backoff (#3736) Equivalent visibility publications were acting as implicit retry commands, so unrelated tab and layout changes could restart failed timeline work. Keep visibility identity stable and reserve immediate retries for explicit user action. * Open the tab chooser beside the pointer (#3735) * feat(app): open the tab chooser beside the pointer Keep keyboard-created and empty-pane New tabs as persistent launcher surfaces, while giving pointer users an anchored chooser at the pane-local plus button. Both presentations resolve the same launch catalogue so future ordering and customization cannot drift. * test(app): follow the anchored tab chooser The browser helpers still searched inside the pane for persistent-launcher controls after clicking the portalled menu trigger. Exercise the menu through its own roles and stable catalogue IDs. * fix(app): restore composer height lifecycle (#3740) Native Fabric can omit the initial content-size callback and retain stale size after deletion. Keep the common composer surface free of platform branches while native and web adapters own their measurement mechanisms. * fix(server): stop quota fetcher from writing provider credentials (#3442) * fix(server): recover already-settled interrupts (#3742) * fix(server): recover already-settled interrupts Provider state can drift from Paseo’s tracked run. Treat an authoritative already-idle interrupt as settled and retire the captured run token so retrying can start new work without weakening ambiguous-cancellation protection. * fix(codex): fence interruption during turn startup Reserve foreground-start ownership before asynchronous provider setup. An interrupt can now cancel preflight before turn/start or wait for an issued start to become interruptible, preventing acknowledged cancellation from leaving unmanaged work. * docs(changelog): prepare 0.5.0 stable release * chore(release): cut 0.5.0 * fix: update lockfile signatures and Nix hash [skip ci] * fix(app): stabilize native composer resizing JavaScript height state competed with native intrinsic layout across draft and agent ownership transitions. Let native inputs own sizing and scrolling while preserving DOM measurement on web. * docs(changelog): prepare 0.5.1 stable release * chore(release): cut 0.5.1 * fix: update lockfile signatures and Nix hash [skip ci] * perf(app): move replica cache validation to restore Add an observational live measurement harness for the row-store migration baseline. Trust already-shaped cache values on persist while retaining full schema validation at the restore boundary. * feat(app): add replica cache row store Ship the platform storage engines behind a dark interface so the cache migration can wire them separately. Both engines share a contract, including atomic writes and destructive schema-version resets. * feat(app): switch replica cache to row storage Persist only changed replica entities so steady-state writes scale with the update rather than the complete cached world. Restore remains an all-or-nothing validated boundary, with whole-host byte-budget eviction. * fix(app): harden replica row persistence Serialize pending batches at write execution time so retries cannot overwrite newer rows or resurrect removed hosts. Reject oversized hosts before storage writes and preserve unchanged directory identities so routine reconciliation stays row-grained. --------- Co-authored-by: BrianAguilarWasco <146237330+BrianAguilarWasco@users.noreply.github.com> Co-authored-by: paseo-ai[bot] <266920839+paseo-ai[bot]@users.noreply.github.com> Co-authored-by: Yuri Gui <yugui923@users.noreply.github.com> Co-authored-by: Agent Op <agentop718@gmail.com> Co-authored-by: Omer Cohen <639682+omercnet@users.noreply.github.com> Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Dan Berindei <dan.berindei@gmail.com>

 ### Cancellation

-Cancellation changes lifecycle state only after the provider acknowledges the interrupt or emits a terminal turn event. If the interrupt is rejected or times out, the agent remains `running` with its active foreground turn intact. Follow-up actions such as replacement, reload, rewind, and Stop must report that failure instead of accepting work they cannot perform. Synthesizing a local cancellation without provider acknowledgment creates a split-brain session: Paseo accepts a new prompt while the provider still owns the previous foreground turn.
+Provider interruption is idempotent at the `AgentSession` boundary. It resolves when the prior
+foreground turn can no longer run, including when the provider reports that it is already idle. It
+rejects only when the provider may still own the turn. Provider adapters translate native errors
+into that contract; lifecycle callers do not interpret provider-specific errors.
+
+After an acknowledged interrupt, the manager settles the captured run even when no terminal event
+arrives or the run was still waiting for its provider turn id. The captured run token prevents an
+older cancellation from settling a newer turn. If interruption is rejected or times out, the agent
+keeps its active foreground turn and replacement, reload, rewind, and Stop report the failure.
+Accepting new work after an ambiguous interruption would create a split-brain session.

 - **Subagents** — exist as part of the creating agent's work, appear in that agent's subagent track, and are archived with it.
 - **Detached agents** — stand on their own after an explicit detach transition, do not appear in the former parent's subagent track, and are not archived with it.

+Parent archive detaches a subagent instead of archiving it when either condition holds:
+
+- The child belongs to another workspace.
+- The child is currently open in an agent tab.
+
+All other children archive with the parent. After the workspace layout hydrates, the client marks
+every managed subagent present in its tabs with `paseo.open-agent-tab.<client-id>=true` through the
+generic agent metadata update. This includes background and restored tabs; navigation does not own
+the marker. Closing a tab sets that client's label to `false`. Any `true` client label keeps the child
+open. Detach clears the parent and every open-tab label. The surviving child therefore becomes a
+normal root agent immediately, and closing its still-open tab archives it.
+
 Runtime ownership is resolved from explicit workspace ID and caller context, never from `cwd`. Workspace creation is a separate operation with `local | worktree` isolation; agent creation only selects an existing workspace.

-Users can also detach an existing subagent from the subagents track. Detach is deliberately a manual lifecycle gesture, not an agent-facing MCP tool. It removes the `paseo.parent-agent-id` label only: it does not stop, archive, move, or restart the agent. The agent keeps its current `cwd` and `workspaceId`, leaves the former parent's track, and behaves like a root agent for tab close, workspace activity, and future parent archive.

 `notifyOnFinish` defaults to `true` for agent-scoped creation and background prompt follow-ups because most delegated work needs to report back to the creating agent. Set it to `false` only for truly fire-and-forget agents or prompts.
+Permission requests are notification checkpoints, not the end of that subscription. The caller is notified again after a permission response when the child finishes, errors, or requests another permission.
+The permission notification includes the normalized request plus the child and request IDs, so the caller can inspect it and respond without fetching agent status.
+A watched child that closes before its finish event also notifies the caller so delegated work cannot disappear silently during archive or workspace teardown.

+
+How assistant text gets from a provider to the screen, and why it is paced on the way. Read this before changing `packages/server/src/server/agent/agent-stream-coalescer.ts`, the reducer queue in `packages/app/src/timeline/session-stream-reducers.ts`, or the reveal in `packages/app/src/hooks/use-revealed-text.ts`.
+
+For terminal output, which is a separate pipeline with separate budgets, see [terminal-performance.md](terminal-performance.md).
+
+## The pipeline
+
+```
+provider deltas (every provider streams incrementally)
+  → AgentStreamCoalescer (daemon, leading + trailing, ≤1 message per 60ms per agent)
+  → recordTimeline: one canonical row per flushed item
+  → agent_stream ws message
+  → reducer queue (app, one commit per frame) → session store
+  → paced reveal (app, per assistant/reasoning item) → markdown blocks → paint
+```
+
+Every provider delivers incremental text, so there is no provider that needs special handling: Claude via `includePartialMessages`, Codex via `agent_message_delta`, ACP agents via `agent_message_chunk`, Pi and OMP via `text_delta`.
+
+## Why the reveal is paced
+
+Arrival is lumpy and there is no fixing that at the source. A 60ms coalescing window carries however many characters the model produced in those 60ms, which swings by an order of magnitude within a single turn. Painting each delta as it lands makes the size of those lumps visible, and that is what reads as jagged.
+
+So arrival sets a _target_ and the reveal rate is derived from the backlog instead. A burst makes the text catch up faster; it does not make the text jump. Shrinking the coalescing window does not fix this — it makes the lumps smaller and more frequent, at the cost of message rate on a daemon loop that already contends with terminal frames and per-message relay encryption.
+
+## Invariants
+
+- **The coalescer is leading + trailing.** The first delta after an idle window flushes synchronously; only the rest of the burst waits for the trailing timer. Reverting to trailing-only adds a full window to the first character of every turn. Same shape and the same reason as `TerminalOutputCoalescer`.
+- **The leading flush adds a canonical row, and that is fine.** A burst's first chunk lands as its own timeline row. `mergeAssistantChunks` / `mergeReasoningChunks` in `timeline-projection.ts` join contiguous same-turn rows, and clients read the projected timeline, so history is unaffected. Tests that assert on raw rows have to account for the extra row; tests that assert on what a client sees do not.
+- **The store holds the full text; only the rendered slice is paced.** Copy, selection, the chat outline, and scroll geometry all read the same string the user can see. Pacing the store instead would leave the bottom anchor chasing a content height that is ahead of the reveal.
+- **First sight of a text is revealed whole.** Only growth is paced. This is what makes history hydration, timeline replay, a virtualized row remounting on scroll, and an already-finished message all render complete on first paint without a special case for each.
+- **Leaving `phase: "streaming"` snaps the reveal.** A completed turn must never be left holding characters. `layoutStream` sets the phase, so anything outside the live head with an active turn is already complete.
+- **The reducer queue commits on a frame, with a timer as the ceiling.** A frame callback never fires in a hidden tab, so a timer races it and wins when nothing is painting — the store has to keep advancing either way.
+
+## Measuring
+
+- **Smoothness (user-perceived):** `packages/app/e2e/browser/agent-stream-smoothness.spec.ts`, gated behind `PASEO_AGENT_STREAM_PERF_E2E=1`. Drives the mock provider's `bursty-stream` model and reports coefficient of variation of characters painted per frame (smoothness) plus p95 gap between visible updates (stalls). Both numbers are needed: a stalled stream is perfectly smooth.
+- **Reproducing bursty arrival:** the `bursty-stream` model in `mock-load-test-agent.ts` emits uneven runs of tokens separated by idle gaps. Burst sizes come from a seeded generator, so a run repeats exactly.
+- **Rate policy in isolation:** `computeRevealStep` in `packages/app/src/agent-stream/text-reveal.ts` is pure; `text-reveal.test.ts` covers convergence and burst flattening without a renderer.
+
+Healthy numbers (2026-08, Expo web against a local dev daemon, real Claude Haiku agent, ~8.5s samples during active streaming). Setting `TEXT_REVEAL_HORIZON_MS` to 0 makes the reveal paint on arrival, which is how the baseline column was taken:
+
+|                                  | paint on arrival | paced |
+| -------------------------------- | ---------------- | ----- |
+| frames that advanced the text    | 6%               | 87%   |
+| chars-per-frame CV               | 4.11             | 1.86  |
+| gap between visible updates, p50 | 317ms            | 17ms  |
+| gap between visible updates, p95 | 383ms            | 17ms  |
+
+Total characters painted is roughly the same either way — the reveal changes when they land, not how many arrive.
+
+Measure the **total** length across every `assistant-message` element, not the last one. A turn emits many assistant messages, so the tail element keeps changing identity and its length is not monotonic; sampling only the tail reads those handovers as resets and reports almost no growth. `sampleStreamFrames` does this correctly.

 - Expo Router navigation (`/h/[serverId]/workspace/[workspaceId]`, `/h/[serverId]/agent/[agentId]`, etc.). The `workspaceId` URL segment is an opaque workspace id, not a directly meaningful filesystem path.
 - `HostRuntimeController` manages saved host connections, reconnection, and per-host runtime state
- `runtime/replica-cache` keeps a non-authoritative per-host display replica in AsyncStorage: only the last focused agent, its workspace, and a short timeline tail. It restores before navigation becomes ready, leaves remote hydration flags false, and is atomically replaced by the normal snapshot-plus-delta synchronization path.
+- `runtime/replica-cache` keeps the complete project, workspace, and active-agent directory plus one short focused timeline tail in a row store. It restores before navigation becomes ready and leaves remote hydration flags false.
+- `runtime/directory-sync` owns directory reconciliation. On reconnect it passes the persisted per-entity cursor through `project.list`, `fetch_workspaces`, and `fetch_agents`; the daemon returns each entity's latest projection when its sequence is newer, plus tombstones.
+- `workspace-labels` owns one sequenced catalog replica per connected host, the deterministic cross-host projection that surfaces spanning hosts use (the filter page, the manager), and the per-host resolution a workspace row's chips use. Two hosts may give one name different colors, so a row resolves against its own host's catalog and a merged answer would be wrong there. Catalogs never synchronize between hosts; assignment creates a missing definition only on the target host. On the daemon, catalog and assignment rewrites share a journaled commit boundary. Startup recovery completes that commit before workspace or catalog publication.
 - `SessionContext` wraps the daemon client for the active session
 - Composer UI and submit/draft behavior live in `packages/app/src/composer/`; screens and panels should integrate it from there instead of dropping composer internals into `components/`, `hooks/`, or `screens/workspace/`
 - Timeline reducers in `timeline/session-stream-reducers.ts` handle compaction, gap detection, sequence-based deduplication
 - Timeline sync correctness is documented in [docs/timeline-sync.md](timeline-sync.md): live streams are for immediacy, `fetch_agent_timeline_request` is authoritative, and catch-up is paged but complete.
 - Voice features: dictation (STT) and voice agent (realtime)

+Pending permission requests are not restored from it. The row store is not encrypted, so the cached
+timeline tail may contain source code, prompts, and tool output; encrypted-at-rest storage is a
+separate product/security decision. Agents, workspaces, and projects have individual rows; the
+focused timeline tail and directory checkpoint each have one row per host. Writes serialize only
+rows whose in-memory identities changed. Restore validates every row before hydration; one invalid
+row clears the cache and starts cold. The 32 MiB byte budget is tracked incrementally from row
+payload lengths and evicts whole hosts in least-recently-written order. After restart, that order is
+an approximation rebuilt from the row store's `readAll()` order. Browser and Electron builds use
+IndexedDB. Native builds use expo-sqlite.
+
+The three directory entity types have independent monotonic sequences and share one daemon
+generation. The daemon retains only the latest projection per entity and bounded tombstones, not an
+event log. A missing, expired, or previous-generation cursor receives a full snapshot. Projects are
+independent records; a project with no workspaces does not need a workspace placeholder.
+
+Workspace label definitions use a separate, explicitly subscribed sequence. The list request both
+fetches and grants live updates for that session. A current cursor receives an empty correlated
+catch-up response when nothing changed; idle sessions and unsubscribed sessions receive no label
+traffic. Workspace assignments stay on the workspace directory sequence.

 **Multi-window (hybrid land-on model).** `createWindow()` in `main.ts` is reusable: `⌘⇧N`/File→New Window, relaunching the app (`second-instance`), and the sidebar "Open in new window" action each open a fresh `BrowserWindow`. Every window shows the full sidebar — there is no per-window project ownership or filtering. "Land on a project" is delivered by a per-`webContents` `PendingOpenProjectStore`: each window pulls its own pending project path on mount (`paseo:get-pending-open-project`) and runs the normal open-project flow, identical to a CLI `paseo <path>` launch.

 > **Window-state v1 limitation:** only the _first_ window of a session restores and persists saved geometry (size/position/maximized). Windows opened via ⌘⇧N / second-instance / "Open in new window" open at the default size, OS-cascaded, and do not persist — this avoids every window stacking on the same restored bounds and fighting over the single window-state store. Lifting this needs per-window state keys.

 Paseo supports configuring custom agent providers through `config.json` (located at `$PASEO_HOME/config.json`, typically `~/.paseo/config.json`).

 All fields are optional with sensible defaults.

+### Profile lists
+
+`terminalProfiles` and `agentProfiles` are both whole-list fields: a config patch replaces the
+array, never merges entries, so a client sends the complete next list on every add, edit, reorder
+and remove. List order is the display order.
+
+Absent and empty mean different things for terminal profiles — omitting the key falls back to
+`DEFAULT_TERMINAL_PROFILES`, while `[]` means the user removed them all. Agent profiles have no
+defaults, so both mean none.
+
+`PersistedConfigSchema` parses strictly, so a daemon that predates a field drops it on write
+rather than storing something it cannot describe. That is why the client gates the agent profiles
+UI on `server_info.features.agentProfiles` instead of letting a save appear to succeed against an
+older daemon.

 > **Opaque-ID invariant:** `workspaceId` is opaque identity, never a filesystem path. Filesystem and git operations take `cwd`/`workspaceDirectory` only — never the id. A compatibility-only first-materialization bootstrap still groups pre-registry agent records by path and Git remote so existing installs retain their legacy records. That grouping never runs against a live registry, and its keys are not runtime project or workspace identity.

+### Workspace label catalog
+
+**Path:** `$PASEO_HOME/projects/workspace-labels.json`
+
+The catalog is shared by every workspace on one host. A definition contains a display name and one
+of the ten identity colour names (`WORKSPACE_LABEL_COLORS` in
+`packages/protocol/src/workspace-labels.ts`); trimmed, collapsed, case-insensitive name identity is
+unique within that file. Definitions have no portable ID or principal owner and remain after their
+last assignment. Editing a label takes a new name, a new colour, or both in one commit, so the two
+fields cannot land half-applied. Workspaces store label names, so a rename and a delete rewrite

+Hierarchy is conveyed through weight and color, not size. Most interface text is `fontSize.base`; compact metadata and hints use `fontSize.sm`. The distinction between a row's primary line and its secondary line is `foreground` versus `foregroundMuted`.
+
+The authored interface ramp uses a 14px base. New native installs default to 15px; web and desktop default to 14px. The Appearance **Interface size** setting is the rendered `fontSize.base` value and scales the rest of the UI ramp proportionally. Primary readable content has its own `fontSize.content`, which defaults to 15px on every platform. It owns message bodies, composer input, Markdown, and PR prose. Controls, navigation, metadata, tool chrome, code, diffs, editors, and terminals stay on their interface or code tokens. **Code size** remains independent.

 Weight has three tiers, applied by role:

- **Screen titles** — the title at the top of a screen — use `<ScreenTitle>` (`packages/app/src/components/headers/screen-title.tsx`), which renders `fontSize.base` at weight `400` on compact and `300` on desktop. Top-of-screen titles are lighter on desktop, not heavier. The workspace screen header follows the same rule (`packages/app/src/screens/workspace/workspace-screen.tsx`).
+- **Screen titles** — the title in app chrome — use `<ScreenTitle>` (`packages/app/src/components/headers/screen-title.tsx`), which renders `fontSize.base` at weight `400` on compact and `300` on desktop. The New workspace hero is the only larger product title; it uses `fontSize["2xl"]` (`packages/app/src/screens/new-workspace-screen.tsx`).
 - **Structural labels** use `fontWeight.medium`. This applies to section labels above a stack of rows (`packages/app/src/components/agent-list.tsx:519-523`, `packages/app/src/components/keyboard-shortcuts-dialog.tsx:63-67`), form field labels above an input inside a modal (`packages/app/src/components/add-host-modal.tsx:19-23`, `packages/app/src/components/pair-link-modal.tsx:24-28`), the title at the top of a modal/sheet/dialog (`packages/app/src/components/adaptive-modal-sheet.tsx:90-94`, `packages/app/src/components/ui/combobox.tsx:1607-1611`, `packages/app/src/components/welcome-screen.tsx:48-53`), action button labels in tight components such as the sidebar callout actions (`packages/app/src/components/sidebar-callout.tsx:218-221`), and inline data emphasis on dense metadata rows (`packages/app/src/components/git-diff-pane.tsx:2322-2327`, `packages/app/src/components/file-explorer-pane.tsx:1115-1122`).

 There is exactly one token per status signal — `statusSuccess`, `statusDanger`, `statusWarning`, `statusMerged` — and every status surface uses it: PR state icons, CI check icons and pies, diff stats, file-change icons, status pills, usage bars. A surface does not get a quieter or louder variant because of where it sits. If a dense list feels loud, that is a density or weight problem; fix the density, not the color. The tokens are generated, not hand-picked — see the rule in `packages/app/src/styles/theme.ts` and regenerate rather than nudging one value.

Lightness is set by hue separation rather than by distance from the surface: at 6pt four dark hues on a light surface all read as one dark blob no matter how much contrast they have. So the light band runs as bright as the contrast floor allows at L=0.62, the last step where all four clear 3:1 against the sidebar's `surface2`; the dark band sits at L=0.72, where danger turns pink above. All four move together; regenerate the set, never one hue.

-Status pills are the status token as foreground on a 10%-alpha tint of the same token (`${token}1a`), with a 20% border (`${token}33`). The `<StatusBadge>` primitive (`packages/app/src/components/ui/status-badge.tsx`) is canonical; a pill never reaches into `palette`.
+Status pills use the status token for text on the shared `surface3` and `border` shell. The neutral shell keeps the signal legible without manufacturing translucent colors outside the theme. The `<StatusBadge>` primitive (`packages/app/src/components/ui/status-badge.tsx`) is canonical; a pill never reaches into `palette`.

 Status dots — the small filled circles next to a host or agent name — are `borderRadius.full` filled with the status token. Which token a given agent state maps to is owned by `getStatusDotColor` (`packages/app/src/utils/status-dot-color.ts`); a row, a group header, and a project icon all call it rather than restating the mapping. They sit in the trailing slot of a sidebar row or as a leading marker on a status pill.

 Identity badges — the project icon, the sidebar host badge, and the PR-panel participant avatar — do not use the theme palette. They draw from the fixed ten-color identity table in `packages/app/src/styles/identity-colors.ts`, whose hexes are held to one contrast band so a color identifies rather than ranks. Project icons and PR avatars use it as a fill with a white letter — that is `identityColor`, one theme-independent hex per identity. Host badges use it as a _foreground_ on both the glyph and the label, which is a different contrast problem that the fill table cannot solve: no single hex clears 4.5:1 against both a near-white and a dark sidebar. Foregrounds therefore come from `identityForeground(name, colorScheme)`, one set per scheme, hue unchanged. That set is generated on the **status family's** lightness and chroma fraction, because a meta row puts a host badge beside a CI check and a diff stat, and two families at different lightness make the brighter one shout. Change the status band and this one changes with it. A host with no color assigned falls back to `foregroundMuted`. The table is theme-independent by design; do not fork it per theme, and do not add hexes to it without recomputing the band.

+Use `packages/server/src/server/file-observer` for recursive filesystem observation. Create one observer service at the owning service boundary, subscribe roots through it, and close it during owner shutdown. Keep platform watchers, directory discovery, exclusion reconciliation, event batching, failure cleanup, diagnostics, and teardown inside the module. A consumer supplies a root and excluded subtrees; it must not branch on the platform or manage child watchers.
+
+Do not replace the Linux implementation with `fs.watch({ recursive: true })`. Node 22 implements Linux recursion in JavaScript by walking the tree and watching every file and directory. Paseo's directory-only Linux watcher already exhausted resources before ignored-tree pruning and a watcher cap were added in [#794](https://github.com/getpaseo/paseo/pull/794).
+
+Closing an observation must remain safe after its root is renamed or removed. Workspace archive removes owned worktrees while releasing observation references, so teardown cannot assume the watched path still exists.
+
+`unsubscribe()` is an awaited barrier. Once it resolves, no scan, reconciliation, queued event, native handle, or callback may remain. `updateIgnore()` is the equivalent barrier for excluded paths: events queued below a newly excluded root cannot be delivered after it resolves. Treat path disappearance while scanning, attaching, or receiving a watcher error as rename/archive churn. Surface permission and resource errors so WorkspaceGit can enter bounded polling.
+
+Linux topology repair is trailing-debounced and scoped to the renamed path. A file rename needs one classification stat; a new or moved directory scans only its subtree. Full-tree scans are reserved for startup and ignore-set replacement. The initial Linux scan conservatively emits existing files discovered before their directory watcher was installed; WorkspaceGit batches these into one refresh. Benchmark this startup cost with pre-populated trees.
+
+Windows and macOS use one native recursive watcher plus an ignored-pruned, directory-indexed inventory. Native events deliver immediately. Named events trigger serialized shallow scans of their parent directories; known directory events also reconcile that subtree. This recovers concrete create and delete paths omitted by coalescing without walking the whole root for each edit. Startup and exclusion changes use an awaited full inventory barrier. Activity arms a full safety audit 30 seconds after it settles, with a 30-second minimum interval and a five-minute starvation bound; pathless native events also trigger an immediate shallow root scan. Observation fails into polling rather than retaining more than 250,000 file and directory entries per root.
+
+Read aggregate health from the owning observer service. Runtime metrics include active observations, native handles, tracked native files, pending events and immediate reconciliation work, scoped and full reconciliation activity and latency, and failure counts. Delayed safety audits do not count as pending work. Closing the service releases every subscription and clears its diagnostics. Do not add path lists, watcher handles, or platform-specific controls to this interface.
+
+Git owns Git-ignore evaluation. The observer accepts absolute excluded roots and applies updates without replacing the observation or exposing its watcher topology. This keeps tracked files inside otherwise ignored directories observable and keeps Git policy out of the filesystem module.
+
+Workspace Git verifies each repository metadata subscription with a one-shot canary inside the Git directory. If the event does not round-trip through the subscription callback, treat the watcher as unavailable and enter degraded polling.

 - **Service** — A workspace script of type `service`: long-running, may bind a port, and carries `health` of `healthy | unhealthy | null` once the daemon has observed it. The only type a sidebar workspace row reports, because a running plain script says nothing about whether the workspace is up; the row names the service and turns danger when its health fails, and where several run the failing one takes the row's single slot.

Two targets, one surface, one RPC (`agent.fork_context`, gated on the `agentForkContext` host feature). UI: the fork menu lives in the assistant turn footer and offers "Fork in a new tab" / "Fork in a new workspace". On a **completed** turn it sits beside the copy button and pins a boundary to that turn, so the fork stops where the turn ended. On the **in-flight** turn it sits beside the progress loader and elapsed timer, and omits the boundary entirely — `selectForkContextRows` projects the whole timeline when no boundary is given, so the fork captures everything **up to now**, including the response still streaming.

+# Local plugins
+
+Local plugins contribute daemon RPCs, native app surfaces, workspace panels, Command Center items,
+app themes, and composer attachment sources from one `index.ts`. Paseo executes the server contribution in a
+subprocess and evaluates the client contribution in the app runtime. Plugin code is trusted code;
+this first slice does not sandbox it.
+
+## Install a directory source
+
+Create a typecheckable plugin project, install its development dependencies, then install it into
+the daemon. `init` only writes the project files; it does not run the package manager.
+
+```bash
+paseo plugin init /absolute/path/to/my-plugin
+cd /absolute/path/to/my-plugin
+npm install
+npm run typecheck
+paseo plugin install /absolute/path/to/my-plugin
+paseo plugin install /absolute/path/to/my-plugin --id another-runtime-id
+paseo plugin ls
+```
+
+The daemon stores directory sources under the root `plugins` object:
+
+```json
+{
+  "pluginsEnabled": true,
+  "plugins": {
+    "my-plugin": {
+      "source": "directory",
+      "path": "/absolute/path/to/my-plugin",
+      "enabled": true
+    }
+  }
+}
+```
+
+The plugin system is disabled unless `pluginsEnabled` is `true`. Changing that root field is
+runtime-safe: run `paseo reload` after editing `config.json`. Enabling starts every configured,
+enabled plugin; disabling tears them all down without restarting the daemon. Plugin source entries
+remain lifecycle-owned and do not reload from manual config edits.
+
+The directory contains an identity-only manifest, one entry point, and local typechecking support:
+
+```text
+my-plugin/
+  paseo-plugin.json
+  index.ts
+  main.client.tsx
+  paseo-plugin.d.ts
+  package.json
+  tsconfig.json
+```
+
+Paseo compiles TypeScript and TSX when loading the plugin, so these packages are development dependencies only.
+The generated declaration file supplies `@getpaseo/plugin` and `@getpaseo/plugin/server` types until the
+SDK is distributed as a public package. Regenerate new plugins with the matching Paseo CLI when the
+SDK contract changes.
+
+```json
+{
+  "id": "my-plugin"
+}
+```
+
+The config key is the runtime plugin ID. The manifest ID is the default selected during install;
+`--id` overrides it. Existing configuration is not renamed when the manifest changes, and the
+runtime does not compare the two IDs. The same directory can be installed under several config
+keys.
+
+Never enable plugins on a user's behalf without explicit permission. Before asking, check the
+target daemon's current `pluginsEnabled` value. State that plugins are trusted, unsandboxed code:
+backend code can access the daemon machine, while client contributions run inside the Paseo app.
+
+Source changes are explicit. Run `paseo plugin reload <id>` to stop and fully tear down the old
+plugin before compiling and starting from disk. A failed reload stays failed; Paseo does not restore
+the old code. Use `enable`, `disable`, and `remove` to manage one plugin. Remove deletes only its
+configuration, never its source directory. The global `pluginsEnabled` switch remains available.
+
+Server contributions can write to stdout and stderr with normal Node logging. Paseo adds `[paseo]`
+entries for loading, ready, stopping, and stopped transitions. Compilation and load failures are
+recorded as stderr entries before a subprocess exists. Inspect the recent in-memory
+tail from the host plugin settings or with `paseo plugin logs <id>`. Reload, disable, and process
+failure retain the tail; removing the plugin clears it. Daemon restarts do not retain the tail, but
+structured copies remain in `$PASEO_HOME/daemon.log`. Plugin output can contain secrets, so do not
+log credentials or tokens.
+

+code lives behind filename boundaries:

+
+Shared files import contracts from `@getpaseo/plugin/server`. Client files import hooks from
+`@getpaseo/plugin`. Plugin UI runs on desktop and mobile across multiple themes: color every
+`Text` from `theme.colors.foreground` or `theme.colors.foregroundMuted`, and size layout from
+`layout.compact`. See `public-docs/plugins/reference.md`.

+```
+
+The contribution function must return cleanup. Server cleanup may be async; Paseo waits for it when
+the plugin is reloaded, disabled, removed, disconnected, or shut down. Cleanup is for resources
+created by plugin code. Paseo removes registered contributions, unmounts surfaces, clears query
+state, rejects pending RPCs, closes the plugin's daemon session, and stops the subprocess. Cleanup
+errors are logged and do not interrupt host teardown.
+
+Paseo owns the route, screen header, Lucide icon validation, close action, theme DTO, layout facts,
+and render error boundary. The contributed component owns the complete body below the header.
+
+RPC contracts validate inputs and outputs in both the app and plugin subprocess. `useRpc` returns a
+typed async function. Use the host-provided `@tanstack/react-query` for request state and caching;
+Paseo gives each plugin installation its own query client.
+
+`usePaseo()` and the handler's `{ paseo }` context expose the same `PaseoApi`: workspaces, agents,
+providers, and daemon config. They do not expose connection lifecycle. A surface borrows the
+selected host's existing connection; switching the screen's host changes both `usePaseo()` and
+`useRpc()` to that host. An offline selected host fails there and never falls through to another
+installation. A server handler owns an IPC-backed daemon session for the life of its subprocess.
+Use plugin RPC for plugin-specific backend behavior that is not a normal Paseo operation.
+
+Each subprocess gets an exclusively owned `plugin:<id>` session. That identity is reserved from
+normal clients, never resumes another session, and is cleaned immediately on exit without reconnect
+grace. During daemon startup, plugin sessions may connect while application WebSockets remain
+paused; the daemon accepts clients only after configured plugins have settled and the initial
+catalog is complete.
+
+When the same plugin contribution exists on multiple hosts, Paseo shows it once in the sidebar and
+adds a host picker to the screen header. The selected host supplies the bundle, RPC transport, and
+query cache. Plugin code cannot address another host.
+
+Workspace panels and Command Center items remain client contributions. The daemon transports their
+compiled bundle without interpreting placement or callbacks. Panel props contain workspace and agent
+IDs. Required-selector hooks read normalized client state synchronously and use shallow equality, so a
+panel does not subscribe to fields it does not render. Command callbacks materialize their snapshots
+only when invoked. Contribution discovery and panel opening never fetch active context through plugin
+RPC. Snapshot DTOs are deeply readonly and frozen at runtime so plugin code cannot mutate normalized
+app state or a memoized selection. Panels use one persisted
+`plugin` workspace-tab target, so reload, disable, removal, and restoration resolve through the
+current installed-plugin catalog. A missing contribution renders unavailable inside the tab.
+
+Command Center callbacks use the selected host's existing `PaseoApi` for normal Paseo operations.
+They use typed plugin RPC only for plugin-specific backend work. Navigation is limited to the
+plugin's registered global surfaces and workspace panels; plugins do not receive Expo Router or
+workspace-layout store access.
+
+## Contribute composer attachments
+
+Register a declarative attachment source backed by a plugin RPC. Paseo owns the attachment menu,
+search picker, drafts, selected pill, and submission. The plugin returns complete text snapshots;
+credentials and vendor API calls stay in the daemon handler.
+
+```ts
+import type { PluginContext } from "@getpaseo/plugin";
+import { search } from "./issues.server";
+import { issues, searchIssues } from "./issues.shared";
+
+export default function contribute(plugin: PluginContext) {
+  plugin.handle(searchIssues, search);
+  plugin.addAttachmentSource(issues);
+  return () => {};
+}
+```
+
+Attachment sources stay scoped to the composer's host. Unlike sidebar contributions, equal sources
+on several hosts are not coalesced. The selected snapshot submits as a text attachment with neutral
+external-resource presentation, so it remains readable if the plugin is removed or an older peer
+drops the optional presentation fields.
+
+## Contribute a theme
+
+`addTheme` takes a small light or dark palette and a display name. Paseo expands it through the
+same semantic builders as the built-in themes, so plugins do not depend on the complete app token
+contract. Unistyles needs every theme name at `StyleSheet.configure` time, so
+`packages/app/src/styles/theme.ts` reserves one light and one dark plugin slot. The appearance
+provider rewrites the matching slot when the selection changes. See [unistyles.md](unistyles.md)
+for the runtime-patching rules the appearance settings share.
+
+`addTheme` is a client registration, so the compiler strips it from the backend bundle. A daemon
+that predates it does not, and the plugin fails to start there. Daemons advertise
+`features.pluginThemes` in `server_info`; the plugin theme catalog is the one place the app reads it, and
+a host without it contributes no themes.
+
+The selection persists as `theme: "plugin"` plus a `pluginThemeId` of `<pluginId>/theme/<themeId>`,
+so equal themes on several hosts coalesce the way sidebar contributions do. Two hosts can answer
+that id with different palettes, so picking a theme records its host through
+`rememberPluginContributionHost` and resolution prefers it; a peer connecting or dropping then does
+not repaint the app. Without a preference the sorted registry snapshot decides, so the result is
+stable rather than arrival-ordered. The app resolves that id
+against the installed catalog on every change; an id nothing contributes falls back to the default
+preference instead of painting the reserved slot's placeholder colors.
+
+See `plugin-examples/local-plugin` for a native surface, `plugin-examples/linear` for a complete
+attachment-source example, and `plugin-examples/catppuccin` for a theme.

 This guide walks through adding a new agent provider end-to-end. There are two integration patterns, and this doc covers both.

+## Provider-native session options
+
+`AgentSessionConfig.providerOptions` carries JSON-safe configuration for the selected provider. The
+names and nesting are the provider's native contract; options are not portable between providers.
+Paseo validates the object with the selected provider's strict schema before constructing a session.
+Unknown keys fail with their `providerOptions.*` path. Paseo-owned controls such as cwd, model,
+prompt, environment, session identity, MCP transport, callbacks, and hooks cannot be passed here.
+
+This Paseo version accepts these keys:
+
+- **Codex:** `approval_policy`, `sandbox_mode`,
+  `sandbox_workspace_write.{writable_roots,network_access,exclude_slash_tmp,exclude_tmpdir_env_var}`,
+  `web_search`, `features.multi_agent_v2`, and `features.network_proxy`. A network proxy object may
+  contain `enabled`, `proxy_url`, `socks_url`, `enable_socks5`, `enable_socks5_udp`,
+  `allow_local_binding`, `allow_upstream_proxy`, `dangerously_allow_all_unix_sockets`,
+  `dangerously_allow_non_loopback_proxy`, `domains`, and `unix_sockets`. See the
+  [Codex configuration reference](https://developers.openai.com/codex/config-reference).
+- **Claude:** `allowedTools`, `disallowedTools`, `additionalDirectories`, `sandbox`, and `settings`.
+  The accepted sandbox fields cover enablement, fail-if-unavailable behavior, excluded and
+  unsandboxed commands, filesystem read/write rules, network domain/socket/local-binding rules,
+  weaker nested sandboxing, ignored violations, and the ripgrep command. `settings` accepts native
+  `permissions.{allow,ask,deny}` and sandbox settings. See the
+  [Claude Agent SDK TypeScript reference](https://platform.claude.com/docs/en/agent-sdk/typescript)
+  and [Claude settings reference](https://code.claude.com/docs/en/settings).
+- **OpenCode:** `permission`, either one `ask`/`allow`/`deny` action or the native per-tool rule
+  object. Supported entries are `read`, `edit`, `glob`, `grep`, `list`, `bash`, `task`,
+  `external_directory`, `todowrite`, `question`, `webfetch`, `websearch`, `codesearch`,
+  `repo_clone`, `repo_overview`, `lsp`, `doom_loop`, and `skill`. See the
+  [OpenCode permissions reference](https://opencode.ai/docs/permissions/). OpenCode permissions are
+  application policy, not an OS sandbox.
+
+Each provider definition owns its option schema and exact MCP preapproval mapping. A new provider
+must fail closed for Hub unattended execution until it can approve one exact injected MCP server
+and tool identity without approving native tools.

 ## Two Integration Patterns

 ### ACP (Agent Client Protocol) -- recommended
@@ -46,10 +81,18 @@ OpenCode owns user message IDs. Do not pass Paseo-generated IDs to OpenCode prom

 `AgentManager` owns the one canonical timeline row for a foreground prompt carrying a Paseo `clientMessageId`. It records that row when `startTurn` accepts, with the wire `messageId` set to the same value. Provider adapters still emit their native user-message echo with the same `clientMessageId` when available; the manager records its provider identity on the internal row without changing or redispatching the wire item. If an adapter emits the echo before `startTurn` resolves, the manager records the provider identity with the row at acceptance. Provider adapters continue to own externally initiated user rows that have no Paseo client identity. Do not perform global transcript text dedupe.

+Active-turn steering is an optional `AgentSession.steerActiveTurn` operation. The manager owns admission against its exact foreground turn, canonical user-message creation, echo reconciliation, and falls back to the normal interrupt-and-replace path only when the adapter reports `unavailable`. An adapter error leaves the steer's fate ambiguous and must surface without an interrupt or retry. Codex calls `turn/steer` with the native expected turn and Paseo client user-message ID. Claude pushes an admitted steer into the exact active SDK query input; isolated control commands remain unavailable. OpenCode calls `session/prompt_async` with an OpenCode-generated message ID; the server queues the prompt while busy and the next LLM call in the same Paseo turn includes it. A missing session reports `unavailable` and uses the normal interrupt fallback.
+
+A steering adapter also owes its interrupt: stopping a turn must discard the steers the provider has not read yet, or one of them resumes the turn the user just stopped. Codex clears pending input when it aborts a turn; Claude does not, so its adapter cancels the SDK messages it queued before calling `query.interrupt()`.
+
+`SteerActiveTurnOptions.clearPendingPermissions` makes permission release part of the provider contract. A provider that accepts such a steer queues it first, denies permissions blocking its delivery, and stops once the steer is read. Steers without the flag leave permissions open. A denied plan remains in the timeline because the pending card was the only other copy of its text.
+
 Rewind accepts the canonical wire `messageId` and resolves it to the provider identity before calling the adapter. A submitted prompt cannot be rewound until its provider echo supplies that identity.

 Submitted user-message wire items carry the same Paseo ID in `messageId` and `clientMessageId`. Provider adapters attach `clientMessageId` only to the echo for that foreground submission; provider history and externally initiated user rows do not have a Paseo client ID.

+Provider adapters must terminalize every transient timeline row before emitting the turn's terminal event. Codex may omit the completed `contextCompaction` item when a turn ends during compaction, so its adapter closes any pending root compaction before forwarding `turn_completed`, `turn_failed`, or `turn_canceled`. A terminal turn must never leave the client showing an operation as still loading.
+
 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. Draft command listing and scratch-session feature listing require an explicit draft model. Do not resolve a default model through catalog discovery. A client-level `listFeatures` implementation may return features from an incomplete, model-less draft and owns which features are valid in that state.

 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.

 The daemon keeps provider snapshots per resolved working directory, with a separate semantic global scope for settings/provider management and requests that do not carry a cwd. Provider catalog probes receive a discriminated `FetchCatalogOptions`: `{ scope: "global", force }` for global catalog refreshes, or `{ scope: "workspace", cwd, force }` for project-scoped refreshes. Providers decide what global means for their runtime; do not infer global by comparing a cwd to the user's home directory.

+`ProviderSnapshotManager` owns one refresh deadline per provider. The deadline starts before the
+availability check and covers that check plus the complete catalog probe. Providers that make
+multiple catalog requests must not apply this deadline separately to each request. The manager
+aborts the shared refresh signal at the deadline. Providers name active catalog operations and
+finish subprocess, server, or session cleanup before rejecting. Timeout errors list the operations
+that were still active when the deadline expired.
+
 Snapshot reads may probe providers only while the requested cwd scope is cold. Once an entry is warm, its `ready`, `error`, or `unavailable` state stays cached until an explicit refresh. Do not add TTL revalidation, focus-triggered refreshes, selector-open refreshes, or config-reload refreshes. Selector-open refetches may read an already-loading or stale React Query, but they must not force provider probing on their own.

 Capable clients receive a compact, content-addressed snapshot. Model rows derive their provider from the containing entry and reference snapshot-level thinking sets. The app persists that compact shape per server and cwd, then sends its hash on the next pull; an unchanged response carries no catalog body. Keep the legacy encoding for clients without the capability. The hash covers the complete client-visible compact snapshot, including status and `fetchedAt`, so explicit refreshes invalidate it even when the discovered catalog is otherwise equal.

The Slice-3 observer entanglement the table fears is already resolved: #1644 moved the status/diff read side into CheckoutSession, so the workspace observer delegates today and this no longer blocks on the WorkspaceController split.

 ### Why this is safe at the dispatch seam (verified)

-`dispatchInboundMessage` builds `a() ?? b() ?? ... ?? dispatchMiscMessage()` and short-circuits on the first non-`undefined` **Promise object** (not its resolved value). Message-type spaces are **disjoint** (no duplicate `case` labels across switches), so at most one dispatcher matches any message — collapsing to delegation cannot change which handler runs. `dispatchTerminalMessage` (2150-2153) already proves this. 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).

+## Release completion and heartbeat

-The user rarely opens the Expo dashboard. A failed EAS build or submit/review job can sit silently until users complain about a stale version. After every stable release, set up a long-delay babysit that re-checks GitHub Actions, EAS builds, and the EAS `Release Mobile` workflow for the release tag. If any build is `ERRORED`/`CANCELED`, any workflow is `FAILURE`, or any required submit/review job fails, surface it immediately. If all builds are `FINISHED` and all required submit/review jobs are `SUCCESS`, confirm and stop.

+store submission passes the completion checklist.

-**Use `create_heartbeat`, never `create_schedule`, for release babysitting.** Babysitting fires back into the current conversation as a wake-up prompt. `create_schedule` starts a fresh agent the user has to find and read; `create_heartbeat` surfaces the build status inline in the conversation that owns the release, where it is impossible to miss. If you find yourself reaching for `create_schedule` for a release babysit, you are about to ship a status report into a void.

+Each heartbeat checks the release tag commit, all GitHub Actions runs for the
+release branch and tag, npm dist-tags, the GitHub Release body and assets,
+desktop updater manifests, the published Docker image, and the applicable EAS
+workflow. Inspect the GitHub Release itself and confirm that the macOS, Linux,
+Windows, and Android APK assets are present along with the channel manifests
+(`latest-mac.yml`, `latest-linux.yml`, and `latest.yml` for stable;

+The changelog is shown on the Paseo homepage. Each bullet is a compact factual record of
+product behavior that changed.

- **Frame everything from the user's perspective.** Describe what changed in the app, not what changed in the code. Users care that "workspaces load instantly" — not that a component no longer remounts.
- **Never mention component names, internal modules, or implementation details.** No `WorkingIndicator`, no `accumulatedUsage`, no `reconcileAndEmitWorkspaceUpdates`. Also no "virtualized lists", no "remount", no "memoization", no "debounced", no "fuzzy ranking", no "controlled input", no "uncontrolled input" — these are implementation words masquerading as user-facing copy.
- **Concrete WRONG → RIGHT examples** (real mistakes from past releases):
+- **Name the exact change.** Prefer `Added <capability>`, `Removed <behavior>`,
+  `Changed <behavior>`, or `Fixed <failure> when <condition>`.
+- **Keep the scope exact.** A conditional bug is not a general reliability problem. Do not
+  broaden one failure into claims that Paseo is now faster, smoother, responsive, or reliable.
+- **Use concrete product and runtime terms.** Git polling, persisted cache, provider catalog,
+  and WebSocket reconnects can identify the affected behavior. Component names, internal
+  modules, code symbols, and implementation techniques cannot: omit `WorkingIndicator`,
+  `reconcileAndEmitWorkspaceUpdates`, remounts, memoization, and controlled inputs.
+- **State the consequence only when the change itself is unclear.** Keep the condition that
+  makes the consequence true. Do not replace a precise change with a broad benefit claim.
+- **Do not invent context.** Mention an upgrade, platform, workload, or user action only when
+  the PR or linked issue establishes that scope.

-  - **Common trap:** when drafting from `git log`, every commit looks like a separate bullet — including the "fix X" commits that landed on top of a brand-new feature in the same release window. Before listing a Fixed entry, check whether the thing being fixed was itself added in this same release. If so, drop the fix and fold it into the feature bullet.
-  - **Example:** if the release adds an in-app browser and also contains a commit "fix: browser pane keyboard handling no longer steals shortcuts", do **not** list the keyboard fix under Fixed. The browser is shipping for the first time, so users will only ever see the working version. The Added entry covers it.
+- **Use the entry's release scope.** Include changes within the matching range in **Changelog scope**.

+The companion surface beside the user's work: Changes, Files, the pull request, and
+anything an agent asks to show alongside its output.
+
+Everything that opens, reveals, hides, or asks about it goes through
+`packages/app/src/workspace-tabs/side-panel.ts`. Nothing else branches on which
+surface the current layout uses.
+
+## Three renderings, two facts
+
+| Layout                 | Rendering                                       |
+| ---------------------- | ----------------------------------------------- |
+| compact                | slide-over overlay, owned by the panel store    |
+| non-compact + splits   | dedicated right pane, owned by the layout store |
+| non-compact, no splits | ordinary tabs in the focused pane               |
+
+The third case is the one that bites. A native tablet renders one pane at a time and
+the tab row only lists the focused pane's tabs, so anything routed into a separate
+side panel pane there disappears with no way back.
+
+## Placement
+
+Where a tab lands is an intent the caller declares, not something the store infers
+from a `paneId` that happens to be in scope. `WorkspaceTabPlacement`
+(`packages/app/src/stores/workspace-layout-actions.ts`) has four modes, and the
+difference between them only shows up when the tab is already open somewhere:
+
+| Mode      | New tab           | Tab already open             |
+| --------- | ----------------- | ---------------------------- |
+| `pane`    | opens in the pane | **moves** to the pane        |
+| `prefer`  | opens in the pane | stays where the user left it |
+| `focused` | focused pane      | focuses it in place          |
+| `ambient` | focused pane      | focuses it in place          |
+
+`pane` is a pane-local affordance — that pane's `+` menu, its empty-state launcher.
+The user is placing the tab and expects it to arrive.
+
+`prefer` is an implicit supporting open — an agent's file link or a failed workspace
+setup. It has an opinion about new tabs only. Yanking a tab out of the pane the user
+deliberately moved it to is the failure this mode exists to prevent.
+
+`ambient` differs from `focused` in one rule: reconciliation opens tabs with nobody
+behind the click, and the side panel can hold focus from an earlier reveal, so an
+ambient open of something the user works _in_ (an agent, a terminal, a browser) is
+pushed out of the side panel. A `focused` open honours the focused pane whatever it
+is, because the user is standing in it.
+
+Deduplication lives in `openTabInLayoutFocused`, so it obeys the placement intent for
+every caller. Do not re-place a tab after opening it.
+
+## Lifecycle
+
+The side panel lives in the ordinary split tree, so it is a pane like any other until
+it empties or the user dismisses it:
+
+- **Close pane** on the side panel **hides** it; its tabs are waiting on the next reveal.
+- **Close pane** on any other pane **removes** it.
+- Closing the Side panel's final tab hides the pane. Revealing it returns the empty launcher.
+  This is close-only: claiming or dragging that tab to another pane leaves the empty Side panel
+  visible.
+- Nothing takes the last visible pane away. `closePane` will not remove it, and
+  neither `closePane` nor `hideSidePanel` will hide it — including the header toggle
+  reaching `hideSidePanel` after every other pane is gone. The gate is one check in
+  `setPaneHiddenInLayout`; do not add a second one upstream.
+
+`closePane` in the layout store owns that distinction. React renders the button and
+does not decide what it means.
+
+Dragging a pane's last tab into another pane collapses the source pane — except the
+side panel, which the user summons and expects to find again, split size and all.
+
+## What the side panel never does
+
+It does not seed itself. Revealing it opens an empty pane with the launcher; the user
+picks what goes in. Detecting a pull request makes the launcher's card available and
+opens nothing. A failed workspace setup adds a background tab to the main pane.
+Running and successful setup never seed tabs.
+
+## Routing preference
+
+**Settings → General → Open supporting tabs in the Side panel**, on by default,
+persisted in client app settings as `openSupportingTabsInSidePanel`. Off means new
+supporting tabs land in the focused pane instead. Mobile ignores it. Explicit actions
+— the header toggle, a pane's `+` menu, the empty-state launcher — are never subject
+to it. The Changes keyboard shortcut and the diff-stat pill above an agent composer are
+supporting opens: they follow the preference and focus an existing Changes tab wherever
+the user left it. When Changes is already visible in the Side panel, the diff-stat pill
+hides the panel without closing the tab. A different visible Side panel tab switches to
+Changes instead.
+
+## The name
+
+The product surface is the **Side panel**. **File Explorer** is still the name of the
+Files view inside it. Persisted identifiers keep their pre-rename spelling: the pane
+id is the literal string `"explorer"` (`SIDE_PANEL_PANE_ID`) and the persisted layout
+key is `explorerPaneIdByWorkspace`. The persisted state schema is strict, so renaming
+either would fail every saved blob and wipe the layout it describes.

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.
+- **Plugin daemon sessions report IPC queue bytes.** Their virtual socket increments `bufferedAmount` before `process.send` and decrements it only in the send callback. Text and binary frames share that ordered queue, so the normal snapshot catch-up and physical high-water gates remain valid for server-side plugin SDK traffic.
 - **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.
+- **Retained terminal tabs in the focused workspace keep their streams.** Hidden mounted terminals continue applying output, so switching tabs does not resubscribe or request a fresh snapshot. The retained-panel LRU bounds the number of live streams; terminals in an unfocused workspace detach.
 - **Terminal size has one daemon-owned claimant.** Focus and direct interaction send a `claim`; later geometry changes from that connection send `update`. A claim transfers ownership even when the dimensions are unchanged, while an update from any other connection is ignored.

 ## Runtime Theme Patching For User Preferences

-Appearance settings (UI/mono font family, font sizes, syntax-highlight theme) are applied by patching every registered theme at runtime with `UnistylesRuntime.updateTheme(name, updater)` — not by threading preference reads through components. `applyAppearance` in `packages/app/src/screens/settings/appearance/apply-appearance.ts` runs from a `ProvidersWrapper` effect on settings load/change and loops all six theme keys, returning `{ ...theme, fontFamily, fontSize, lineHeight, colors.syntax }`.
+Appearance settings (theme, UI/mono font family, font sizes, syntax-highlight theme) are owned by `packages/app/src/appearance`. Its provider subscribes once and synchronizes Unistyles when settings or plugin contributions change. `applyAppearance` patches every key in `REGISTERED_THEMES`, returning `{ ...theme, fontFamily, fontSize, lineHeight, colors.syntax }`.

 This works without `useUnistyles()` because every consumer already reads these tokens through `StyleSheet.create((theme) => …)` (or the `withUnistyles`/`uniProps` path for the markdown renderer), so patching the theme repaints tracked views through the native ShadowRegistry with no React re-render.

 Gotchas:

 - **Patch all themes, not just the active one.** The active theme can change and adaptive mode can flip light/dark; patching every key keeps the active key current and makes ordering vs `setTheme`/`setAdaptiveThemes` irrelevant. The effect depends on the settings values (not on `theme`), so it cannot loop.
+- **The reserved plugin keys are the exception to that ordering.** A plugin-contributed theme is rebuilt from its palette, which discards the appearance patch, so the appearance provider writes the matching light or dark slot before applying font and syntax preferences. See [plugins.md](plugins.md).
 - **Narrow the discriminated union before spreading.** `updateTheme`'s updater returns the theme union; spreading the union widens `colorScheme` to `"light" | "dark"`, which is assignable to neither concrete member. Branch on `t.colorScheme` so each branch spreads a single narrowed theme type (no `as`).
- **`lineHeight.diff` is the code/diff line-height axis** — it is coupled to the code-font-size control (≈ `codeFontSize * 1.5`). Do NOT use it for prose. Markdown body line-height scales with the UI ramp (`Math.round(theme.fontSize.base * 1.4)`); routing prose through `lineHeight.diff` clips text at small code sizes.
+- **`lineHeight.diff` is the code/diff line-height axis** — it is coupled to the code-font-size control (≈ `codeFontSize * 1.5`). Do NOT use it for prose. Markdown body line-height scales with content size (`Math.round(theme.fontSize.content * 1.4)`); routing prose through `lineHeight.diff` clips text at small code sizes.
 - **High-churn draft values** (live-while-typing in the appearance preview) bypass the theme: apply them as inline styles marked with `inlineUnistylesStyle` so per-keystroke values don't grow the `#unistyles-web` CSS registry.
- **Mounted parsed content uses `AppearanceStyleBoundary`.** Markdown, syntax-highlighted code, and tool-call detail bodies can contain memoized/custom renderer trees that do not naturally re-run when runtime-patched appearance tokens change. Wrap the parsed surface once with `packages/app/src/components/appearance-style-boundary.tsx`; do not add local "appearance key" props at each callsite.
+- **The app shell uses one `AppearanceStyleBoundary`.** Runtime-patched numeric theme values are baked into Unistyles web classes rather than CSS variables, while parsed/memoized content also does not naturally re-run when appearance tokens change. The boundary sits below stable runtime providers in `app/_layout.tsx` and remounts the visual shell once. `applyAppearance` patches the active theme before inactive registry entries so its subscribers receive the committed values in the same update. Do not add local appearance keys or nested boundaries.
 - **Dynamic font tokens stay widened.** `fontFamily`, `fontSize`, and `lineHeight` on `commonTheme` are annotated `string`/`number` (not narrowed by `as const`) so the updater's return assigns; the platform default stacks live in `DEFAULT_UI_FONT_STACK` / `DEFAULT_MONO_FONT_STACK`.
