 # runner, with corepack pinning pnpm 10.24 in eas.json, local == build.
 #
-# Every merge to main that touches the mobile app reconciles, per platform:
-#   1. Store builds: when no production build matches the current native
-#      fingerprint, or the latest build's version differs from app.config.ts,
-#      cut a new build and submit it (TestFlight + Play internal track). Native
-#      changes therefore ship a binary on merge, and bumping `version` is all
-#      it takes to start the next release train — the first build of a version enters
-#      external-TestFlight beta review immediately, and later builds of the
-#      same version auto-approve until that version is released. After App
-#      Store approval, Apple closes the release train and `version` must be
-#      bumped before another iOS build can be submitted. Releasing to the App
-#      Store stays a manual App Store Connect step.
-#   2. OTA: publish a production-channel update for each platform where at
-#      least one finished production build matches the current native
-#      fingerprint. Older binaries of the same major version with a matching
-#      fingerprint receive it too; the major version is part of the
-#      fingerprint (apps/mobile/fingerprint.config.js), so a new major never
-#      reaches the previous major's store binaries over the air. Until a
-#      build for the new fingerprint finishes, the OTA is skipped rather than
-#      published into the void.
+# Every merge reconciles native fingerprints and publishes matching OTAs.
+# iOS prereleases use the testflight profile (3.0.0); App Store binaries use
+# production and the committed app version, built manually. Both receive OTAs
+# for their own major version. Android continues using production automatically.
+# TestFlight beta review may still be required for subsequent builds.
 # Hold native-change PRs (the "📱 Native Change" label) and merge them as a
 # batch to avoid a store build per PR.
 # workflow_dispatch remains as a manual override for both modes (e.g. to
 # retry an errored build or force an OTA).
-# Manual v2-preview builds keep the production app identity and disable OTA.
-# They auto-submit to TestFlight and the Google Play closed testing track v2.

 - Server features are services; transports stay thin. A `ws.ts` RPC handler, HTTP route, or MCP tool decodes input, calls one service method, and maps errors. See [Effect services](docs/internals/effect-services.md).
 - `apps/web/src/components/ui` exports own their look. Pick a `variant` or `size`; do not restyle one with `className`. If none fits and the look is a generic concept, add a variant to the component; a look that belongs to one feature stays in that feature's own component, not in `components/ui`. Layout classes (width, flex, margin, position) belong on the parent. `shadcn/no-restyle` fails lint on violations. See [Web UI](docs/internals/web-ui.md).
 - Inferred types over annotations. `any` is the enemy.
-- Comments describe how a thing is used, and move when the code moves. To be used mostly to describe functions, not to annotate every line of behavior.
+- Comments say why: a constraint, an external quirk, or an invariant the code can't show. Don't restate names or signatures, narrate steps, or record history. `t3code/no-low-value-comments` catches the mechanical cases.
 - Our users drive agents all day and notice a dropped frame, a lying spinner, and a stale label. No continuously repainting animations; they peg the GPU on high-refresh displays.
 - If a rule here fights the task in front of you, say so loudly and get a human sign-off before breaking it.

-// Pool registry for multiple backend processes. This file is the entry
-// point for the concurrent-Windows+WSL-backend feature; see the design
-// notes below before extending it.
-//
-// Current state:
-//   - `DesktopBackendManager.ts` exposes a per-instance factory
-//     (`makeBackendInstance(spec)`); the pool calls it once for the
-//     Windows primary at startup, and `DesktopWslBackend.reconcile`
-//     calls it through `pool.register` to bring up the WSL instance
-//     when the user enables it.
-//   - The primary spec wires `configResolve` to
-//     `DesktopBackendConfiguration.resolvePrimary` and the
-//     `onReady`/`onShutdown` callbacks to the window service. WSL
-//     instances wire `configResolve: configuration.resolveWsl(...)`
-//     and skip onReady/onShutdown — the window only follows the primary.
-//   - The pool exposes `register(spec)` and `unregister(id)`. Each
-//     registered instance gets its own child scope, so unregister can
-//     stop it cleanly without tearing down the pool. The primary's id
-//     refuses unregister.
-//   - Settings: `wslBackendEnabled: boolean` + `wslDistro: string | null`.
-//     The legacy `wslMode: "local" | "wsl"` swap setting is migrated on
-//     load. IPC surface is `setWslBackendEnabled(boolean)` +
-//     `setWslDistro(string | null)`; both persist and then call the
-//     orchestrator's reconcile. No swap, no rollback, primary stays up.
-//   - `getLocalEnvironmentBootstraps()` (plural) returns one entry per
-//     pool instance currently registered with bootstrap info. The
-//     primary keeps the "primary" id; WSL instances are "wsl:default"
-//     or "wsl:<distro>".
-//   - `pickFolder` accepts an optional `targetEnvironmentId`. Omitting
-//     it gives the Windows picker — what every existing caller gets,
-//     and what non-WSL users see. WSL targets route to the wsl helpers.
-//   - Web settings UX: a plain toggle for "WSL backend" plus a distro
-//     picker that shows up when the toggle is on. Default-off, so
-//     users who never opted in see the same surface as before.
-//
-// Renderer-side wiring (apps/web/src/environments/local/):
-//   - reconcileLocalSecondaryEnvironments() runs at app boot and after
-//     WSL settings changes. It reads getLocalEnvironmentBootstraps(),
-//     skips the primary (which the existing primary/ runtime owns),
-//     and for every other entry POSTs the shared bootstrap token to
-//     /api/auth/bootstrap/bearer on that backend's URL, fetches the
-//     descriptor, builds a SavedEnvironmentRecord marked desktopLocal,
-//     writes the bearer to the secret store, and opens a connection
-//     through the same saved-env path remote envs use.
-//   - The desktopLocal marker filters records out of saved-env
-//     persistence, so toggling WSL off or switching distros doesn't
-//     pollute the user's settings file. The sidebar, CommandPalette,
-//     env switcher, and project-id routing all read the saved-env
-//     registry, so the WSL backend shows up there without any
-//     per-surface changes.
-//
-// Browser validation (2026-05-17, dev:desktop with wslBackendEnabled=true,
-// wslDistro="Ubuntu"):
-//   - Two backends listening on distinct loopback ports
-//     (server.log: 13773 primary, 13774 wsl).
-//   - Per-instance log files: server-child.log + server-child-wsl_Ubuntu.log.
-//   - Distinct environment ids reported by each backend's
-//     /.well-known/t3/environment (Windows vs Linux platform).
-//   - Renderer completes the bearer-token bootstrap against the WSL
-//     backend (POST /api/auth/bootstrap/bearer 200), obtains a
-//     ws-token (POST /api/auth/ws-token 200), and holds an
-//     ESTABLISHED WebSocket connection to both ports (netstat).
-//
-// Migration history (commits):
-//   1. Reshape `DesktopBackendManager` into an instance factory and route
-//      consumers through the pool. Pool held a single instance. (a8fc7845)
-//   2. Drop `DesktopState.backendReady`. The window owns its own
-//      readiness latch via onReady / onShutdown callbacks. (425c7d0b)
-//   3. Per-instance log routing via DesktopBackendOutputLogFactory. (563820ed)
-//   4. Add register/unregister to the pool. (a0eaf560)
-//   5. Wire WSL through the pool: settings rename, BackendConfiguration
-//      split, DesktopWslBackend orchestrator, new IPC, web compat.
-//      (b1622191 + 31ce3add + 627c80cb)
-//   6. Widen getLocalEnvironmentBootstrap to *Bootstraps (plural). (bad66041)
-//   7. pickFolder takes optional targetEnvironmentId. (5d80468d)
-//   8. Settings UX: toggle + distro picker, no swap dialog. (eb5a03ea)
-//   9. Register WSL backend as desktop-local saved env via
-//      reconcileLocalSecondaryEnvironments. (1c7e7873 + c17897bd)
-//   10. CommandPalette enables file-manager picker for desktop-local

- *   apps.
  * - `sandbox=true`: keeps the OS-level renderer sandbox enabled. Critical
  *   when paired with `contextIsolation=false` — without sandbox, the preload
  *   has full Node access (`require`, `fs`, `child_process`, ...) and that
  *   `require` would land on the page's shared `globalThis`, giving any

- *   `contextIsolation="no"` is truthy → contextIsolation stays ENABLED →
- *   react-grab can't see the React DevTools hook.
- *
- * Defense in depth: `apps/desktop/src/main.ts` also runs a

- *    generic file). A cycle can hide behind platform resolution: a `.tsx`

  *    Dynamic `import("...")` calls are excluded from this rule on purpose:
  *    they are the deliberate async escape hatch (e.g. composer-draft cleanup
  *    reaching `lib/attachmentUpload`), and Metro resolves them after both
  *    modules have initialized, so they cannot create an initialization cycle.
- *
- * 2. Cross-layer edges are ceilinged, not yet banned. `state`, `lib`,
- *    `native`, and `components` still reach upward into `features` at known
- *    sites (the app composition root `lib/runtime.ts` legitimately wires
- *    feature layers). Ceilings count unique `from -> to` module pairs across
- *    all platforms, including dynamic imports, and may only shrink: when you
- *    remove one of these imports, lower the constant in the same PR.
- *

- * Detects markdown that the renderer draws as a block requiring a definite

- * lists, and blockquotes when requested by the caller.
- *
- * Fenced code blocks and tables report an intrinsic width equal to their
- * widest line, which is effectively unbounded. A user bubble sizes itself
- * from its content
- * (`maxWidth` with no `width`), so Android lays the bubble's children out
- * during the unclamped intrinsic pass — where the surrounding paragraphs
- * collapse to a single line — and never repositions them once the width is
- * clamped back to `maxWidth`. The result is siblings drawn on top of each
- * other inside an over-tall bubble. Pinning the bubble's width removes the
- * intrinsic pass entirely, which is the same reason review-comment bubbles
- * already carry an explicit width.
- *
- * Ordered lists hit the same Android layout bug because each item contains a
- * flexing content column inside a shrink-to-fit row.
- *
- * A four-space ordered marker is only treated as a list when the preceding
- * non-empty line is a less-indented list item. This keeps standalone indented
- * code out of the heuristic while covering nested lists.

- * Rebuild an isolated dev database from a pruned snapshot of the real
- * ~/.t3 database, then run this checkout's migrations against it.
- *
- * `vp run migrate-dev-db` from a worktree:
- *   1. Nukes `<worktree>/.t3/userdata/statev2.sqlite`.
- *   2. Copies a slice of the real db (`~/.t3/userdata/statev2.sqlite`,
- *      attached read-only): the schema, and every row except those of
- *      deleted, archived, and settled threads, which are nearly all of a
- *      long-lived database. It then prunes that to the most recently updated
- *      projects and, per project, the most recent threads that have fully
- *      stopped, with
- *      their forks and subagents. Working, settled, and archived threads, and
- *      threads with pending recovery, are skipped, and scheduled tasks and
- *      queued effects are dropped, so the dev server never adopts live work.
- *      Auth sessions, pairing links, command receipts, and provider
- *      runtime rows are dropped — pair a fresh browser against dev.
- *   3. Runs migrations on the result. Because the clone carries the real
- *      `effect_sql_migrations` table, this proves a new migration applies
- *      on top of the real applied set, and the slot check below catches
- *      the silent failure where two branches claim the same
- *      `Migrations/NNN_` id (the second one's CREATE TABLE is skipped).
- *
- * The event log (`orchestration_events`) is pruned per stream while
- * `sqlite_sequence` and the projection cursors carry over untouched, so new events keep appending
- * after the old high-water mark and projection cursors never rewind.

- *
- * Only listeners owned by T3 terminal processes and explicitly configured

- *
- * Listening ports are published only after a bounded HTTP(S) probe finds a

- * Positive and negative results are cached briefly by candidate URL and listener identity,
- * limiting repeated requests without leaving stale classifications around.
- *
- * Polling is reference-counted via scoped `retain`. A single layer-scoped fiber
- * polls forever, but each tick is a no-op when the retain count is zero.

- * The registry watches settings; when an instance's config changes (or
- * the entry disappears), the registry tears down the affected instance's
- * scope and rebuilds — that's the entire hot-reload story.
- *
- * What rest-of-server reads from here:
- *   - `getInstance(instanceId)` — for routing turn/session calls.
- *   - `listInstances` — for snapshot aggregation in `ProviderRegistry`.
- *   - `listUnavailable` — `ServerProvider` shadows for instances whose
- *     driver is not registered in this build (rollback / fork tolerance).
- *   - `streamChanges` — coalesced "registry mutated" pings so consumers
- *     can re-pull lists or re-broadcast.
- *
- * The live implementation (`makeProviderInstanceRegistry`, `layer`) also
- * provides its sibling mutator.
- *
- * Materializes every entry in a `ProviderInstanceConfigMap`:
- *
- *   - When the entry's `driver` matches a registered driver, the registry
- *     decodes the opaque `config` envelope through `driver.configSchema`
- *     and calls `driver.create()` inside a fresh child scope. The
- *     resulting `ProviderInstance` is stored keyed by instance id,
- *     alongside its scope so the entry can be torn down independently.
- *   - When the entry's `driver` is unknown to this build (fork, rollback,
- *     in-flight PR branch), the registry emits an `"unavailable"` shadow
- *     `ServerProvider` snapshot instead of failing. This is what makes
- *     downgrades and fork-hopping safe per the
- *     `forward/backward compatibility invariant` in
- *     `packages/contracts/src/providerInstance.ts`.
- *   - When the entry's config fails schema decode, the registry logs and
- *     emits a shadow snapshot with the schema detail — same bucket as an
- *     unknown driver.
- *
- * Unlike the pre-Slice-D layer, the registry now holds mutable state
- * (`Ref`s + `PubSub`) and exposes an internal mutator
- * (`ProviderInstanceRegistryMutator`) whose `reconcile` method diffs a
- * fresh config map against the live state, tearing down removed instances
- * and building new ones without disturbing unaffected instances.
- *
- * Every live instance runs inside its own child `Scope`. The registry's
- * own scope owns all child scopes via finalizers, so closing the registry
- * tears every instance down in reverse order; closing a single instance
- * (via `reconcile` removing it) leaves the rest untouched.

- * ProviderRegistry - Provider snapshot service.

- * The live layer aggregates per-instance snapshot streams into a

- *
- * Historically this Layer composed four per-kind Live Layers
- * (`CodexProviderLive`, `ClaudeProviderLive`, …) that each exposed a
- * `ManagedServerProvider`. Those Lives were deleted during the driver /
- * instance refactor — every driver now carries its `snapshot: ManagedServerProvider`
- * bundled onto the `ProviderInstance` the registry produces.
- *
- * Each configured instance (including multi-instance setups like
- * `codex_personal` + `codex_work`) contributes one `ProviderSnapshotSource`,
- * keyed by `instanceId`. Instances whose driver is unavailable or whose
- * config failed to decode are merged from `instanceRegistry.listUnavailable`
- * as shadow snapshots so the UI can render their exact unavailable reason.
- *
- * Cache paths on disk are now keyed by `instanceId`. Because
- * `defaultInstanceIdForDriver(kind) === kind` for built-in kinds, existing
- * `<kind>.json` files remain the on-disk location for that driver's default
- * instance. Identity-less legacy cache contents are ignored and replaced by
- * the first live refresh.

- * Minimal React hook shim for tests that call components as plain functions
- * instead of mounting a renderer. Slots are keyed by call order, mirroring
- * React's own rules-of-hooks contract, and `useMemoCache` emulates the React
- * Compiler runtime so compiled components can execute unmodified.
- *
- * This module must stay free of runtime `react` imports: it is loaded from
- * inside `vi.mock("react", ...)` factories, and a value import would recurse
- * into the in-progress mock. Wire it up in each test file (mock calls cannot
- * live here because vitest hoists them per test module):
- *
- * ```ts
- * import { reactHookHarness } from "~/test/reactHookHarness";
- *
- * vi.mock("react", async (importOriginal) => {
- *   const actual = await importOriginal<typeof import("react")>();
- *   const { reactHookHarness } = await import("~/test/reactHookHarness");
- *   return {
- *     ...actual,
- *     useCallback: reactHookHarness.useCallback,
- *     useMemo: reactHookHarness.useMemo,
- *     useRef: reactHookHarness.useRef,
- *     useState: reactHookHarness.useState,
- *   };
- * });
- * vi.mock("react/compiler-runtime", async () => {
- *   const { reactHookHarness } = await import("~/test/reactHookHarness");
- *   return { c: reactHookHarness.useMemoCache };
- * });
- * ```
- *
- * Call `beginRender()` before each component invocation and `reset()` in
- * `beforeEach` to drop persisted state between tests.

+## Measuring renders
+
+[`render-counter.ts`](../../apps/mobile/src/features/development/render-counter.ts) counts the
+components React rendered in each commit and why: a changed state slot, changed props, or
+context. It wraps the DevTools hook from the first import in `index.ts` and loads only when
+`__DEV__` and `EXPO_PUBLIC_T3_RENDER_COUNTER=1`, so release bundles never contain it. The walk
+skips subtrees React bailed out of. A probe that checks `flags & 1` on every fiber reports
+renders that never happened, because bailed-out fibers keep flags from older commits.
+
+[`measure-renders.mts`](../../apps/mobile/scripts/measure-renders.mts) drives a measurement from
+outside the app. It evaluates the counter's globals through Metro's Hermes inspector proxy, which
+works the same for iOS simulators and Android emulators and needs no taps, `simctl`, or `adb`. It
+starts a real provider turn through the server, opens the thread with an app link, records a window
+mid-stream, and prints the median renders, commits, top components and top causes. Expo drops inspector sockets whose `Origin` is not the URL Metro advertises, so
+pass that URL (the LAN address with `--lan`) as `--metro`.
+
+```bash
+EXPO_PUBLIC_T3_RENDER_COUNTER=1 vp run dev:client   # in apps/mobile, then pair the app
+node apps/server/src/bin.ts auth session issue --base-dir <base-dir> --token-only
+node apps/mobile/scripts/measure-renders.mts --server <server-origin> --token <token> \
+  --metro http://<metro-lan-host>:8081 --project-root <scratch-dir>
+```
+
+`--route /settings/usage` instead reloads the app, opens that path from Home and records a 6 s window over
+mount and data settling, with no provider turn and no `--server`, `--token` or `--project-root`.
+With `--server` as well, the app reloads, opens that path (`/` stays on Home) and the reply streams in a
+new thread the app never shows, which measures what streaming elsewhere costs the screen in front.
+
+Compare before and after on the same base, on the same device, with the median of three runs.
+Provider output varies run to run, so a single run or a comparison across bases is noise.
+
+## React Compiler
+
+Metro runs the compiler only because `experiments.reactCompiler` is set in `app.config.ts`. Expo
+then passes `supportsReactCompiler` to `babel-preset-expo`, which owns the plugin options; there is
+no `babel.config.js` entry to look for. Release bundles use `panicThreshold: "NONE"`, so a function
+the compiler can't prove safe ships unmemoized with no build error.
+[`reactCompilerCoverage.test.ts`](../../apps/mobile/src/reactCompilerCoverage.test.ts) runs the
+same preset over every source file. It fails on a new bailout, and on a file in `KNOWN_BAILOUTS`
+that now compiles, so the list only shrinks. When you fix a listed file, delete its entry and its
+manual `useMemo`/`useCallback`/`memo` in the same change. Most mobile bailouts are `try` without
+`catch` or with `finally`, and refs read during render; see [Web UI](web-ui.md#react-compiler)
+for the usual rewrites. Mobile runs `t3code/no-manual-memo` with `allowMemoHooks`, so memo
+directives are errors but the hooks stay legal until `KNOWN_BAILOUTS` is empty.
+`t3code/no-hookless-use-function` rejects a `use*` function that calls no hook, since the compiler
+leaves it uncached. A platform stub of a real hook, such as an `.android.ts` file, keeps the hook
+name and suppresses the rule with a reason.

 - Builds a self-contained CLI archive per platform (`t3-<version>-<platform>-<arch>.tar.gz`, `.zip` on Windows) in the same job as that target's desktop artifact and attaches them to the GitHub Release with a `SHA256SUMS` file, on every channel, for five targets: macOS arm64, Linux x64 and arm64, Windows x64 and arm64.

+## Reclaim database space
+
+T3 Code removes superseded internal history on its own while it runs; your
+conversations are kept. Databases created before this shrank automatically
+still hold the freed space on disk until a one-time offline repair returns it
+and turns on automatic shrinking. Settings > Storage (web and desktop) or
+Settings > Maintenance (mobile) suggests the repair when at least 1 GiB can be
+reclaimed.
+
+Run `t3 doctor` on the machine that hosts the environment. It reports the
+database size and the space it can reclaim, then asks which repairs to run;
+pass `--fix` to run the recommended ones without a prompt (for scripts), or
+`--dry-run` to only report. An installed background service for the same data
+directory is stopped for the repair and started again afterwards, also when
+the repair fails. Quit a server you started by hand, or the desktop app, first:
+the repair refuses to touch a database that is in use. Use `--base-dir` for a
+different data directory.
+
+The repair can take several minutes on a large database. It rebuilds the
+database through a temporary copy, so it needs free space of about the
+database's size twice over: once in the system temporary directory (`TMPDIR`
+or `/tmp` on Linux and macOS) and once next to the database for its
+write-ahead log.
+
+If you upgraded from a version before 0.1.0, its database (`state.sqlite`) is
+still kept next to the current one so you can roll back. `t3 doctor` offers to
+delete it, but never selects that repair for you and `--fix` skips it: once it
+is gone, a version before 0.1.0 starts with no threads or settings.

- * Splits the historical "provider kind" concept into two:
- *
- *   - `ProviderDriverKind` is the implementation kind selector (e.g. codex,
- *     claudeAgent, a fork's `ollama`, …). It picks which driver package
- *     handles the protocol, the probe, the adapter, and text generation.
- *
- *   - `ProviderInstanceId` is the routing key (a user-defined slug).
- *     Threads, sessions, runtime events, and persisted bindings reference
- *     instance ids — never driver kinds — so a user can configure multiple
- *     instances of the same driver (e.g. `codex_personal` + `codex_work`),
- *     each with independent driver-specific configuration.
- *
- * Forward/backward compatibility invariant
- * ----------------------------------------
- * `ProviderDriverKind` is intentionally an **open** branded slug, not a closed
- * literal union. The server hosts forks, ships in PRs that add drivers, and
- * users frequently roll between branches and forks. Any of those paths can
- * leave `ServerSettings`, persisted thread state, or session bindings
- * referencing a driver that the currently-running build does not know about.
- *
- * The rule: parsing any of those payloads must always succeed, and the
- * runtime is responsible for marking the unknown driver/instance as
- * "unavailable" rather than crashing. Built-in drivers shipped by the core
- * product happens to register in a given build is not part of the contract
- * layer. Driver availability is discovered through the runtime registry.
- *
- * Driver-specific configuration is similarly opaque at the contracts layer:
- * drivers live in (or will be extracted to) their own packages and own their
- * config schemas. The contracts package only knows the envelope.

 The \`t3-code\` MCP server provides app-owned orchestration. Treat these concepts distinctly:
 
 - A delegated task/subagent is child work owned by the current thread. Use \`orchestrator_capabilities\` to discover the current provider/model IDs from the same live catalog as the composer, including configured custom models. Do not treat a native tool's model list as the full list of available subagent models. Prefer native subagent tools for same-provider work only when they support the chosen model. Use \`delegate_task\` with that provider instance and model when native tools cannot, including for same-provider work. Also use \`delegate_task\` for cross-provider or explicitly T3-owned child tasks. For a child task that needs a separate checkout, use \`delegate_task\` with \`isolation:"worktree"\` across any provider or model. It starts from the parent local commit and runs project setup; uncommitted edits are not copied. Retain each returned \`taskId\`, and use \`task_status\` or \`task_cancel\` to manage it. The returned \`childThreadId\` is backing storage for the subagent, not the target for starting another delegated review round.
 - \`t3_thread_launch\` and \`create_threads\` create ordinary top-level T3 conversations. Use them only when the user explicitly asks for separate/new/top-level threads or conversations. Never use them merely because the user said "subagent" or requested parallel delegated work.
-- For every T3 delegated review round, call \`delegate_task\` again. Include the original brief, prior findings, responses, and unresolved objections in each new task prompt. Track each round by its own \`taskId\`. Use a distinct \`clientRequestId\` per round, stable across retries of that round. Do not use \`t3_thread_send\` on \`childThreadId\` to continue a delegated review.
-- \`schedule_task\` creates persistent recurring work in the app scheduler. Pass \`schedule\` as a structured object, never as JSON text: \`{"type":"interval","everyMs":3600000}\` for an interval, or \`{"type":"fixed_time","timeOfDay":"09:00","weekdays":[1,2,3,4,5]}\` for a wall-clock schedule, or \`{"type":"webhook"}\` to run on each request to the returned \`webhookUrl\` (the run sees the request only through \`{{body.path}}\`-style placeholders in the prompt). By default runs return to the current thread, which suits orchestrating: each trigger arrives here and you delegate or dedupe; set \`bindToCurrentThread=false\` only when the user wants a fresh thread for every run. After scheduling a timer, report the returned cadence and next run time; for a webhook, report its \`webhookUrl\`, or say T3 Connect remote access is needed if it is missing.

 - When you need a secret from the user (a token, API key, or webhook signing secret), call \`request_secret\` so they enter it privately, then pass the returned \`secretRef\` to the tool that needs it, e.g. \`signature.secretRef\` on a webhook task for a sender that signs requests such as GitHub. A \`secretRef\` works once. Never ask for a secret in chat, never invent one, and never repeat one.

 \`t3_thread_launch\` is the single-thread launch tool.

When the T3 tools are absent and \`T3_ACP_MCP_NODE\` is present, call the same tools through the terminal: \`ELECTRON_RUN_AS_NODE=1 "$T3_ACP_MCP_NODE" \${T3_ACP_MCP_ENTRYPOINT:+"$T3_ACP_MCP_ENTRYPOINT"} acp-mcp-call orchestrator_capabilities '{}'\` (\`T3_ACP_MCP_ENTRYPOINT\` is unset when T3 runs as a standalone executable). Delegate with \`acp-mcp-call delegate_task '{"task":"...","target":{"providerInstanceId":"...","model":"..."},"mode":"async","clientRequestId":"..."}'\`.

-/**
- * PiAdapterV2 — orchestrator-v2 adapter for the Pi coding agent
- * (https://pi.dev), driving `pi --mode rpc` over stdio JSONL via `PiRpc.ts`.
- *
- * Design intent: honor the user's Pi customizations. The process is spawned
- * with no `--no-*` flags, so the user's extensions, skills, prompt templates,
- * AGENTS.md / SYSTEM.md context, settings.json, custom models, and auth all
- * load exactly as they do in the `pi` TUI. Sessions are stored by Pi itself
- * (default `~/.pi/agent/sessions/`), and the session file path is the durable
- * `nativeThreadRef`, so a thread started in T3 can be resumed from the TUI
- * and vice versa.
- *
- * Turn lifecycle: `agent_settled` is the only terminal signal. `agent_end`
- * merely closes one low-level run — compaction retries, auto-retries, and
- * queued continuations may still follow it, so the turn stays open until Pi
- * reports the session settled. An extension can start detached compaction as
- * that signal unwinds, so the adapter confirms Pi is idle before terminalizing.
- *
- * Extension UI: Pi extensions raise dialogs through `extension_ui_request`.
- * Dialog methods become v2 runtime requests (`confirm` → approval_request,
- * `select`/`input`/`editor` → user_input_request); answers travel back as
- * `extension_ui_response`. `notify` becomes a completed activity item.
- * Terminal-only decoration such as status, widget, title, and editor-text
- * updates has no matching T3 surface and is ignored.

- * - Mid level: Custom-make the list of segments and call QrCode.encodeSegments().
- * - Low level: Custom-make the array of data codeword bytes (including
- *   segment headers and final padding, excluding error correction codewords),
- *   supply the appropriate version number, and call the QrCode() constructor.

+ * again on clients when they splice appends onto what they hold, so both sides
+ * must reach the same state from the same input.
+ *
+ * It models a small terminal: the last `LIVE_LINES` lines form a window that
+ * cursor movement can rewrite, so `\r` progress bars and multi-line redraws
+ * (docker pull, pnpm, test reporters) keep only their latest frame. Older lines
+ * are fixed text. The model has no width, so lines never wrap.
+ *
+ * - Colours and text attributes (SGR) survive as canonical `ESC[0;…m` codes.
+ *   Every line starts from the default style and resets at its end, so any line
+ *   boundary is a safe place to cut. `terminalOutputSpans` reads them back.
+ * - Cursor moves, line and screen erases, and save/restore are applied. Other
+ *   escape sequences (titles, modes) and control characters are dropped.
+ * - Only the last `maxChars` survive, cut at a line boundary when possible.
+ *
+ * Chunks can split an escape sequence, so the unfinished fragment is carried in
+ * `pending` until the next chunk arrives.

  * A host's rollup is a list of runs, not a list of checks: while a workflow is being re-run — or
  * while a second run of it is already live — the same check arrives twice, and both copies reach
  * the reader as what looks like a duplicate. Nothing in a check carries an id, so the name is what
  * identifies it, qualified by the workflow it belongs to since two workflows are free to name a
  * job the same thing.
- *
- * Within a group the newest run is the one worth showing: a re-run is the answer that replaces the
- * one before it, and a run that never said when it happened loses to one that did. A tie goes to
- * whichever came last, because a host lists a re-run after the run it repeats.
- *
- * The order is the host's own, held at the place each check first appeared, so a re-run landing
- * mid-read replaces a row where it stands instead of reshuffling the list under the reader.
- *
- * Two checks that survive under the same name are then genuinely different ones, since they came
- * from different workflows — each is shown as `workflow / name`, the way GitHub writes it itself.
- * A survivor whose workflow the host did not name keeps its bare name rather than being qualified
- * with nothing.

+A description of a set of changes to a file tree to be made as part of
+a git commit, modeled as zero or more file `additions` and zero or more
+file `deletions`.
+
+Both fields are optional; omitting both will produce a commit with no
+file changes.
+
+`deletions` and `additions` describe changes to files identified
+by their path in the git tree using unix-style path separators, i.e.
+`/`.  The root of a git tree is an empty string, so paths are not
+slash-prefixed.
+
+`path` values must be unique across all `additions` and `deletions`
+provided.  Any duplication will result in a validation error.
+
+### Encoding
+
+File contents must be provided in full for each `FileAddition`.
+
+The `contents` of a `FileAddition` must be encoded using RFC 4648
+compliant base64, i.e. correct padding is required and no characters
+outside the standard alphabet may be used.  Invalid base64
+encoding will be rejected with a validation error.
+
+The encoded contents may be binary.
+
+For text files, no assumptions are made about the character encoding of
+the file contents (after base64 decoding).  No charset transcoding or
+line-ending normalization will be performed; it is the client's
+responsibility to manage the character encoding of files they provide.
+However, for maximum compatibility we recommend using UTF-8 encoding
+and ensuring that all files in a repository use a consistent
+line-ending convention (`\n` or `\r\n`), and that all files end
+with a newline.
+
+### Modeling file changes
+
+Each of the the five types of conceptual changes that can be made in a
+git commit can be described using the `FileChanges` type as follows:
+
+1. New file addition: create file `hello world\n` at path `docs/README.txt`:
+
+       {
+         "additions" [
+           {
+             "path": "docs/README.txt",
+             "contents": base64encode("hello world\n")
+           }
+         ]
+       }
+
+2. Existing file modification: change existing `docs/README.txt` to have new
+   content `new content here\n`:
+
+       {
+         "additions" [
+           {
+             "path": "docs/README.txt",
+             "contents": base64encode("new content here\n")
+           }
+         ]
+       }
+
+3. Existing file deletion: remove existing file `docs/README.txt`.
+   Note that the path is required to exist -- specifying a
+   path that does not exist on the given branch will abort the
+   commit and return an error.
+
+       {
+         "deletions" [
+           {
+             "path": "docs/README.txt"
+           }
+         ]
+       }
+
+
+4. File rename with no changes: rename `docs/README.txt` with
+   previous content `hello world\n` to the same content at
+   `newdocs/README.txt`:
+
+       {
+         "deletions" [
+           {
+             "path": "docs/README.txt",
+           }
+         ],
+         "additions" [
+           {
+             "path": "newdocs/README.txt",
+             "contents": base64encode("hello world\n")
+           }
+         ]
+       }
+
+
+5. File rename with changes: rename `docs/README.txt` with
+   previous content `hello world\n` to a file at path
+   `newdocs/README.txt` with content `new contents\n`:
+
+       {
+         "deletions" [
+           {
+             "path": "docs/README.txt",

+  This must refer to a git branch (i.e.  the fully qualified path must
+  begin with `refs/heads/`, although including this prefix is optional.
+
+  Callers may specify the `branch` to commit to either by its global node
+  ID or by passing both of `repositoryNameWithOwner` and `refName`.  For
+  more details see the documentation for `CommittableBranch`.
+
+  ### Describing Changes
+
+  `fileChanges` are specified as a `FilesChanges` object describing
+  `FileAdditions` and `FileDeletions`.
+
+  Please see the documentation for `FileChanges` for more information on
+  how to use this argument to describe any set of file changes.
+
+  ### Authorship
+
+  Similar to the web commit interface, this mutation does not support
+  specifying the author or committer of the commit and will not add
+  support for this in the future.
+
+  A commit created by a successful execution of this mutation will be
+  authored by the owner of the credential which authenticates the API
+  request.  The committer will be identical to that of commits authored
+  using the web interface.
+
+  If you need full control over author and committer information, please
+  use the Git Database REST API instead.
+
+  ### Commit Signing
+
+  Commits made using this mutation are automatically signed by GitHub if
+  supported and will be marked as verified in the user interface.

- * Turns the per-platform CLI archives of one release into the npm packages
- * behind `npx t3` / `npm i -g t3`: one `@t3code/t3-<platformKey>` package per
- * archive holding the archive's contents verbatim, plus the `t3` launcher
- * that lists them as optionalDependencies and execs the one npm installed.
- * The bytes a user gets from npm are therefore the release archive's, and
- * running them needs neither a Node runtime, npm, nor a native build.
- *
- * Output layout under `--output-dir`:
- *
- *   @t3code/t3-<platformKey>/      archive contents flattened + package.json
- *   @t3code/t3-<platformKey>.tgz   the same tree as an npm tarball
- *   t3/                             launcher: package.json, bin/t3.js, README.md
- *   t3.tgz                          the launcher as an npm tarball
- *
- * The tarballs are what gets published. `npm publish <dir>` always drops
- * `node_modules/` (npm-packlist ignores it whatever `files` says, and
- * bundleDependencies needs an arborist tree these flattened installs are
- * not), whereas `npm publish <tarball>` uploads the bytes as given.
