Problem: when a wrapper or another package manager provides Pi (mise, a
`PNPM_HOME` wrapper such as nub, Nix), `pi update` cannot update it and
prints "pi cannot self-update this installation." Users with several
machines have to remember which tool updates Pi on which machine.
Example:
```sh
export PI_SELF_UPDATE_COMMAND="mise use -g npm:{packageName}@{version}"
pi update
# Updating pi with mise use -g npm:@earendil-works/pi-coding-agent@1.4.0...
# Updated pi from 1.3.0 to 1.4.0
```
or in `~/.pi/agent/settings.json`:
```json
{ "selfUpdateCommand": ["nix", "profile", "upgrade", "pi"] }
```
Behavior:
- `pi update` still checks pi.dev first. The command runs only when a
newer release exists, or with `--force`, and the release note prints
first.
- Placeholders come from that release: `{packageName}`, `{version}`,
`{installSpec}` (`<packageName>@<version>`). A package rename announced
by pi.dev flows into them.
- `PI_SELF_UPDATE_COMMAND` takes precedence and is split on whitespace
(no quoting). The setting is argv, for arguments with spaces, and is
read only from global settings, so a project's `.pi/settings.json`
cannot inject a command.
- The configured command replaces Pi's own update logic for every
install method, including installer-managed installs: it is explicit
user intent.
- Exit code 0 does not prove an update. Pi reports "Updated pi from X to
Y" when its own `package.json` now shows Y (in-place updates) or when
`pi --version` from PATH reports Y (wrappers such as mise or Nix that
install each version into a new directory). Otherwise it warns: ``Ran
<cmd>, but `pi --version` reports X, not Y.``
- "cannot self-update this installation" now mentions the env var and
setting.
Docs: `docs/cli.md` (new "Custom update command" section),
`docs/settings.md`, `docs/environment-variables.md`, `--help` env list,
regenerated `schemas/settings.schema.json`.
Tests: unit tests for argv resolution and placeholders in
`test/config.test.ts`; CLI tests in `test/package-command-paths.test.ts`
for env precedence over the setting and the managed install, global-only
setting gated by the version check, and command failure. `npm run check`
passes.
Manual end-to-end check with real mise 2026.10.23 in a sandboxed HOME,
running this branch as the mise-installed 1.3.0 (`PI_PACKAGE_DIR`
pointing at mise's install):
| Scenario | Result |
|---|---|
| `mise use -g npm:{packageName}@{version}` | mise installs 1.4.0;
`Updated pi from 1.3.0 to 1.4.0` |
| Already 1.4.0 | `pi is already up to date (v1.4.0)`, mise not run |
| In-place `npm install -g --prefix <dir> {installSpec}` via the setting
| `Updated pi from 1.3.0 to 1.4.0` |
| Command `true` (exit 0, installs nothing) | ``Ran true, but `pi
--version` reports 1.3.0, not 1.4.0.`` |
This PR is AI-generated.
Fix docs and `--help` drift: update the provider checklist to the
`src/api` layout, fix broken MCP anchors, and document `/mcp`, `pi mcp
add|remove`, `PI_CLEAR_ON_SHRINK`, and `"disabled"` timeouts.

Scripts wait in arrival order for a free worker instead of failing
immediately. The wait counts toward timeout_ms, honours abort, and is
capped at 60 seconds. PI_CODEMODE_MAX_WORKERS raises the process-wide
limit of two workers for hosts running many sessions in one process.

Sends copied text to the terminal with OSC 52 after the local clipboard
write, as over SSH, for remote clients without SSH variables such as
multiplexer attaches and remote IDE daemons.

Chord: README rewritten for the new runtime; notes.md and requests.md removed, their open limits and
decisions folded into spec.md section 12; guide and spec status lines updated. Durable: drops the
pico-v5 handoff and delta findings, renames the Pico spec, and uses current Chord terms. Delta README,
issue categories, and PI_RADIUS_GATEWAY updated.
Report idle, working, blocked, done, and error to terminals that support
the Program Status Protocol. ProcessTerminal sends the support query with
the keyboard query and reports only after the terminal answers before DA1;
PI_PROGRAM_STATUS=1|0 overrides detection. Interactive mode reports runs,
compaction, extension dialogs, and logins. agent_settled now carries
aborted so cancelled runs report idle.

Separate stable and development entrypoints, exclude remote harness code from distributions, and verify isolated consumer installs before release. Fixes#9132.
Split StdinBuffer's incomplete-sequence wait from the lone-ESC wait so SSH and PI_TUI_ESC_TIMEOUT can reassemble split Alt+Enter without delaying Escape or mouse/CSI buffering.
* fix(tui): prevent split Alt+Enter from interrupting
Increase the escape-sequence timeout over SSH and allow high-latency terminals to override it with PI_TUI_ESC_TIMEOUT.
Fixes#7876
* docs(coding-agent): shorten escape timeout description
