Merge pull request #357 from dignfei/feat/docker-adopt-existing-container

feat(docker): attach a case to an already-running container

Conflicts came from work that landed after the PR was opened, and each is
resolved onto the newer abstraction rather than by keeping the older code:

- `defaultDockerCommandForMode` is registry-driven since #347, so the PR's
  `runsAsRoot` arm became `overlays.docker.rootCommand` (claude only). Claude
  Code still refuses `--dangerously-skip-permissions` as root in 2.1.261 and the
  refusal is visible only inside the container, so an adopted root container
  otherwise just shows a dead pane. Which flag to drop is a per-CLI fact, and
  `test/cli-registry-no-id-branching.test.ts` forbids expressing it as a branch.

- The probe's mode list and its mode -> binary table both duplicated the
  registry. They now read `enabledCliIds()` / `discovery.binaries[0]`, which is
  also what fixes the merge's silent regression: the hand-written list predates
  `omp`, and the run menu gates every docker case on this probe, so owned
  containers would have lost that mode. `shell` needs no arm — it declares no
  binary, so it is dropped from the lookup and reported available regardless.

- The per-mode `mode === 'claude' && !cliDir` chain in `tmux-manager.ts` is one
  `missingCliMessage(mode)` gate since #347; the PR's docker exemption moved onto
  it. Its test now pins the single gate instead of counting seven arms.

- The create arm keeps #349's swap-limit warning filter, which the adopted arm
  never reaches; the run-mode list gains `omp` from #353.

The reliable sequence is: poll `GET /api/v1/sessions/:id` until `.data.pid` is
non-null, then `wait-output` for the composer's own marker (`bypass`, the status
bar of a CLI spawned in bypass mode) with a short timeout, handling the trust
dialog only as the bounded fallback (`trust` matched → send `\r` → wait for
`bypass` again). Do not probe `trust` first and Enter blindly: the dialog text
stays in the terminal buffer for the life of the session, so a `trust` probe with
`from=buffer` keeps matching on every later run and the Enter lands in a ready
composer. A worked version is in
dialog only as the bounded fallback.
⚠️ **The fallback is not a bare `\r`.** Claude Code 2.1.252 unnumbered the dialog's
options, reversed them and highlights `No, exit`, so an Enter sent blind quits the
CLI and the pane dies seconds after the spawn. Read the `❯` marker off the current
frame (`GET /api/v1/sessions/:id/terminal?full=1`), send `ESC [ B` while it is on
`No, exit`, re-read, and confirm only once it is on `Yes, I trust this folder`.
Reading the current frame is also what keeps this correct on later runs: the dialog
text stays in the terminal buffer for the life of the session, so a `trust` probe
with `from=buffer` keeps matching long after the dialog is gone. A worked version is in
[`extending-codeman.md`](extending-codeman.md#seam-3-http-api-and-cli).

# The CLI registry
Every run mode Codeman can launch — Claude Code, Terminal/Shell, OpenCode, Codex, Gemini, Antigravity, Pi, Grok, DeepSeek Harness and OMP — is a `CliEntry`: a data record describing how to find the binary, how to build its command line, what environment it needs, and what it can do. Code that used to ask "which CLI is this?" asks the entry instead.
## Where it lives
| File | What it holds |
| ------------- | ------------------------------------------------------------------------------------------------- |
| `types.ts` | The `CliEntry` interface and everything under it. Read this first. |
| `stock.ts` | The shipped catalog. **The only file allowed to name a CLI id.** |
| `schema.ts` | Zod validation, including the cross-field checks that reject an incoherent entry at LOAD time. |
| `argv.ts` | The argv engine: the only code that turns typed tokens into a command string. |
| `patterns.ts` | The NAMED value patterns (`model`, `uuid`, `path-segment`, …) and the regex-compilation guard. |
| `profiles.ts` | The names of behaviours that genuinely need code, kept import-free so `schema.ts` can validate one. |
| `registry.ts` | Loading, merging `~/.codeman/clis.json`, and the accessors (`getCli`, `enabledClis`). |
`src/session-cli-registry-bridge.ts` maps the legacy per-mode option bag onto the engine, and `src/utils/cli-resolver.ts` / `src/utils/cli-launcher.ts` do registry-driven binary resolution and launcher-profile dispatch.
## The override file
`~/.codeman/clis.json` (instance-scoped through `dataPath()`) holds overrides and custom entries only, never a copy of the stock catalog: `{ "clis": { "<id>": { ...partial entry... } } }`. Objects merge key-wise onto the stock entry, arrays replace wholesale. **The file must be mode 0600**; the loader refuses any group/world permission bit, read bits included, so a file created with a normal umask (0644) is ignored until you `chmod 600` it. Every reason a file was ignored or an entry dropped is logged once, prefixed `[cli-registry]`, on the first load. A stock entry whose override fails validation falls back to the shipped definition; a custom entry that fails is dropped. The file is read once per process and re-read only on restart.
## The shape of an entry
```ts
interface CliEntry {
id: CliId; // 'codex'
label: string; // 'Codex' — shown in menus
shortBadge: string; // tab badge, e.g. 'CX'
accent: string; // single hex colour
enabled: boolean;
stock: boolean; // set by the loader; a custom entry can never claim it
order: number;
kind: 'agent' | 'shell';
discovery: CliDiscovery; // how to find and prove the binary
launch: CliLaunch; // the structured argv template
env: CliEnv; // exports, tmux setenv keys, the env-override allowlist
capabilities: CliCapabilities; // what every call site reads instead of the id
overlays: CliOverlays; // remote-SSH / Docker pane commands, credential store
}
```
`capabilities` is the important part. It is what `isExternalCliMode()`, `isAltScreenStripMode()`, `hooksAvailableForMode()` and every other former per-mode branch actually read.
### Three capabilities that must stay independent
`external`, `hooks` and `altScreen` describe three different, deliberately unequal sets, and deriving any one from another has already shipped a bug. `shell` has no hooks but is **not** an external CLI, so a hooks predicate written as `!isExternalCliMode()` accepted `until=stop` on a shell session and then blocked the caller for their entire timeout. `deepseek` is the mirror image: it IS external and it DOES have hooks.
`test/cli-capability-predicates.test.ts` asserts that no two of the three are equivalent across the catalog, so collapsing them fails the build rather than a user's session.
## Arg-template safety
The composed command line is interpolated into `bash -c "…"` inside tmux, which makes command construction a security boundary. Four independent layers keep config out of it:
1. **Config contains no shell text.** There is no `command: "..."` field anywhere in the schema. An entry declares a sequence of typed tokens; `argv.ts` is the only place that turns them into a string, and it owns every separator itself — one space between tokens, ` || ` between fallback variants. Neither can originate from config, because config has no field that could hold either.
2. **Every literal is validated at LOAD time** against a safe-word pattern (no space, quote, backtick, `$`, `;`, `&`, `|`, redirection, parens, braces, newline or backslash). A bad literal **rejects the whole entry** rather than being dropped, because a silently dropped flag would change security-relevant behaviour — losing `--no-approve` is not a cosmetic difference.
3. **Values resolve through NAMED patterns.** A value placeholder selects a `TokenPattern` (`model`, `uuid`, `slug`, `path-segment`, `tool-list`, …) from `patterns.ts`; config can never supply its own regex for a value, so a `clis.json` structurally cannot widen its own validation. A value that fails its pattern drops the whole argument, exactly as the hand-written builders did: an invalid `--model` omits `--model`, it never substitutes something else.
4. **Escaping is independent of validation.** `renderToken()` re-checks the resolved value before emitting it unquoted, and single-quotes anything else — so even a value that somehow bypassed validation is quoted, never concatenated raw.
The only config-supplied regexes are `discovery.version.regex` and `discovery.identity.regex`. Both run against **command output** rather than a shell token, both are compiled through `compileVersionRegex()` (length cap, nested-quantifier rejection, never the `g` flag), and the output they see is truncated first.
## Named profiles: the escape hatch
Some differences genuinely need to run code rather than be described. Those are **named profiles**: a capability field holds a profile NAME, and the implementation lives in one place keyed by that name — never by CLI id.
- `discovery.launcherProfile` — for a CLI whose binary is not the agent. `dsh` boots `$DSH_HOME/profiles/<name>`, so "installed" and "runnable" have different answers; the profile answers both, plus why a specifically-named target will not work. Implemented in `utils/cli-launcher.ts`.
- `env.setenvProfile` — per-CLI environment setup that is more than a list of keys, such as DeepSeek's status bridge.
- `capabilities.transcript` — which on-disk history reader understands this CLI (`claude-jsonl`, `codex-rollout`, `deepseek-zstd`, `omp-jsonl`, `none`).
- `capabilities.echo.predictProfile` — the predictive-echo model a composer needs.
The names live in `profiles.ts`, which is kept free of imports so `schema.ts` can validate a name at load time. A profile this build does not implement is a load-time error naming the field, rather than a CLI that silently looks permanently uninstalled.
## DeepSeek: the four assumptions it breaks
DeepSeek is worth reading before assuming an entry looks like its siblings — the schema carries four extensions because of it.
| What it breaks | How the registry expresses it |
| ------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------ |
| `dsh` is a profile LAUNCHER, not the agent, so "installed" is not "runnable". | `discovery.launcherProfile` + `discovery.launcherTargetParam`. |
| Its permission switch is the **`DSH_PERMISSION_MODE` env var**, not a flag — the harness has none. | `env.configSetenv` (so the ordinary `privilegedParams` clamp still reaches it) **and** `capabilities.privilegedEnvKeys`. |
| It is the only non-claude mode with real hook signals, and for it that is a per-SESSION question. | `capabilities.hooks: 'supervised'` — a third state, not a boolean. |
| Its transcript is zstd session files, one frame per write. | `capabilities.transcript: 'deepseek-zstd'`. |
## Identity probes
`discovery.identity` asks the binary whether it is the program we meant, and it runs **before** the version probe, because a version probe cannot tell an impostor from the real thing. Debian ships an unrelated `dsh` (dancer's shell) that answers `--version` perfectly happily, and npm carries squatters for both `pi` and `grok`.
`discovery.version.requireVersionMatch` is the weaker companion: a binary whose version output has the wrong shape counts as ABSENT rather than present-with-unknown-version. That is what a short, generic binary name needs, and it is what keeps `codeman doctor` and the run mode from telling the user opposite things about the same binary — both read the same regex off the same entry.
## The no-id-branching rule
`test/cli-registry-no-id-branching.test.ts` fails the build if a CLI id comparison appears outside the stock catalog. It builds its id list from the live catalog, blanks comment lines before scanning (comments legitimately quote the pattern to explain why a branch was removed, and blanking rather than dropping is what keeps reported line numbers pointing at the real file), and keeps an allowlist in which **every entry carries its reason**.
It matches four shapes, not one: `mode === '<id>'`, `mode !== '<id>'`, `case '<id>':`, and `['<id>', …].includes(mode)`. The first version matched `===` only, and that gap was not academic — the refactor it guards converted the `===` sites and left the negated ones, so 36 `!==` branches survived it, including a seven-mode chain auto-enabling Ralph under a comment asking the next person to keep it in step with a predicate by hand while the sibling code path already read the capability. A guard that sees half the shapes reports a count measured over the half it happens to catch.
The allowlist is not a formality. If a branch is about what a CLI can DO it belongs in `CliCapabilities`; the entries that remain are things that are not CLI-behaviour branches at all — chiefly the legacy per-mode `<Mode>Config` objects on `POST /api/sessions`, which are a fact about the public HTTP API rather than about any CLI, plus a few documented cases where `mode === 'claude'` is genuinely the right question (Read My Mind reads Claude's _own_ transcript, so a capability there would be actively wrong).
## Two namespaces called `param`
`launch.params` keys, `env.configSetenv[].fromParam` and `capabilities.privilegedParams[].param` all name a **launch param**. The **legacy wire field** a param arrives as is a separate namespace, and `launch.legacyConfigAliases` is the only bridge between the two.
This matters because it is invisible when it is wrong. `capabilities.privilegedParams[].param` is the multi-user bypass clamp's only handle on a CLI's privilege switch, and a name from the wrong namespace clamps **nothing**: no load error, no failing test, the clamp simply stops running. Codex is the entry where the two names differ (`bypassApprovals` as the param, `dangerouslyBypassApprovals` on the wire), so it is the one that catches a regression. `schema.ts` rejects any entry naming a param it never declared, on both `configSetenv.fromParam` and `privilegedParams.param`.
## Fields declared for later
`shortBadge`, `accent`, `capabilities.echo`, `capabilities.wheelForward`, `capabilities.keyboardAccessory` and `capabilities.maxFrameBytes` are **declared but not yet read**. They all describe frontend behaviour, and the frontend is deliberately untouched here: `app.js`, `terminal-ui.js` and `styles.css` keep their own hand-authored per-CLI rules, and moving them is its own piece of work verified by a browser/mobile suite the CI gate cannot see.
Treat those values as **transcribed, not authoritative** — nothing enforces that `echo.policy` matches `_updateLocalEchoState`'s fallthrough, or that `accent` matches the gradient CSS paints, so re-measure before wiring one up. A field that is both wrong and unread is worse than an absent one, because the next reader trusts it; `test/cli-registry-no-id-branching.test.ts` pins the list so it cannot quietly grow, and wiring one up makes its line there fail, which is the direction you want.
`overlays.credStore` is in the same category, for a sharper reason: the Docker credential-seeding path still reads its own `CRED_STORES` table, because this shape allows ONE store per CLI and the live table needs two for gemini (`.gemini` for the CLI's own auth plus `.config/gcloud` for Vertex), while deepseek declares none here even though `.dsh` is seeded. Wiring it means making the field an array and correcting those two entries — a change to credential seeding, which is simultaneously the worst thing here to get wrong and the least covered by tests, since every docker IO path is no-op'd under vitest.
Everything else in the interface is live, including `overlays.remote` / `overlays.docker`, which back `defaultRemoteCommandForMode()` and `defaultDockerCommandForMode()` directly. Those two used to be hardcoded `Record<…CommandMode, string>` tables duplicating the registry with nothing keeping the two in step; `test/location-overlay-commands.test.ts` pins every resulting command as a literal string.
## Resolve at call time, never at import
Anything reading the registry must resolve it when it is asked, not when its module is first imported. `sessionModeSchema()`, `allowedEnvPrefixes()`, `dependencyRegistry()` and each resolver's `searchDirs` thunk all re-read the catalog per call.
A module-level const freezes at first import, and the failure is asymmetric: a CLI enabled while the server is running moved the run menu but not the frozen surface, so validation rejected a mode the menu offered, or `codeman doctor` reported a catalog nobody had any more.
## Adding a CLI
1. Add a `CliEntry` to `stock.ts`.
2. Add a golden spawn-command pin to `test/cli-registry-spawn-golden.test.ts`, a row to `test/cli-capability-predicates.test.ts`, and its remote/docker commands to `test/location-overlay-commands.test.ts`.
3. That is usually all. If you find yourself wanting to add an `if` somewhere, the guard test will tell you — and the answer is a capability field, or a named profile if it genuinely needs to run code.

# Docker Compose deployment
This configuration builds the Codeman application image locally from this checkout. It does not download or depend on a pre-built Codeman image.
For the Compose configuration, environment settings, storage migration, and macvlan networking examples, see the [Docker deployment guide](../docker/README.md).
The image includes Claude Code, Codex, Gemini CLI, and OpenCode. Authenticate a CLI from its Codeman session; credentials are never baked into the image.
## Prerequisites
- Docker Engine or Docker Desktop with Docker Compose v2
- A reachable Docker daemon
The application container mounts the Docker daemon socket so Codeman can create and manage its isolated Docker cases. Treat anyone who can administer this Compose project as having Docker-host-equivalent access.
## Start
Copy the environment template, set a strong password, and confirm `CODEMAN_APPDATA_PATH`. The example maps `/mnt/user/appdata/Coding/codeman` on the host to `/home/${CODEMAN_RUNTIME_USER}` in the container, preserving Codeman state and CLI credentials outside Docker-managed volumes.
```sh
cp docker/.env.example docker/.env
```
On PowerShell, use the following command instead.
```powershell
Copy-Item docker/.env.example docker/.env
```
On Linux, run the stack with the start script. It determines `PUID` and `PGID` from the owner of `CODEMAN_APPDATA_PATH`, and `DOCKER_SOCKET_GID` from the configured Docker socket, before invoking Compose. A root-owned application-data directory is rejected so the runtime account cannot become UID 0.
```sh
bash docker/Start-Codeman.sh
```
On other platforms, run Compose directly. `PUID` and `PGID` default to `1000:1000`; set them in `docker/.env` when the application-data directory has a different owner.
```sh
docker compose --env-file docker/.env -f docker/docker-compose.yaml up --build -d
```
Open `http://localhost:3000` and sign in with the username and password from `docker/.env`.
## Operations
The local image is tagged `codeman:local` by default. Change `CODEMAN_IMAGE` in `docker/.env` if a different local tag suits your environment.
```sh
docker compose --env-file docker/.env -f docker/docker-compose.yaml logs -f codeman
bash docker/Start-Codeman.sh
docker compose --env-file docker/.env -f docker/docker-compose.yaml down
```
`CODEMAN_APPDATA_PATH` holds Codeman state and survives container recreation. Remove that host directory only when deliberately resetting the installation.
`CODEMAN_CASES_PATH` must be an absolute path on the Docker host. Compose mounts it at the same path inside Codeman, so the host daemon can bind the managed workspace into isolated Docker cases. Do not set it to `/home/${CODEMAN_RUNTIME_USER}/codeman-cases`.
Compose passes `CODEMAN_APPDATA_PATH` into Codeman as `CODEMAN_DOCKER_HOST_HOME`. Codeman uses that value to translate generated Docker seed, credential and hook-secret bind sources from the container's home path into paths visible to the host Docker daemon.
If `docker info` reports `SwapLimit=false`, set `CODEMAN_DOCKER_DISABLE_SWAP_LIMIT=1`. Isolated cases retain their configured memory limit. Codeman omits the unsupported swap-limit option and filters only the daemon's exact swap-capability warning while retaining every other Docker create error.
If that directory was created by an earlier root-running image, change its ownership to the configured `PUID:PGID` before starting this version. This preserves existing CLI credentials and session state while allowing the unprivileged runtime account to use them.
## Updating
Codeman updates itself from **App Settings → Updates**, as it does on a bare host. The checkout mounted at `/opt/codeman` is the same directory Compose builds from, so the update's `git checkout` and rebuild land on the host and survive container recreation; the restart is the server exiting, which `restart: unless-stopped` turns into a relaunch on the new build.
That applies application code only. A release that changes `docker/server.Dockerfile`, `docker/docker-compose.yaml`, or adds a key to `docker/.env.example` needs the image rebuilt or the container recreated, which a container cannot do to itself. The updater detects each case and refuses with a message naming what changed; run `docker/Start-Codeman.sh` on the host to apply those.
`CODEMAN_REPO_PATH` overrides which checkout is mounted. It defaults to the compose project's parent directory, so it normally needs no setting. Point it at a directory that is not a git checkout and in-app updates are reported as unavailable.
Full detail, including the fingerprint baseline and the troubleshooting table: [`docker-self-update.md`](docker-self-update.md).
## Docker cases
The default socket path is `/var/run/docker.sock`, which works with a standard Linux Docker Engine. The Bash start script detects its numeric group ID. When running Compose directly, set `DOCKER_SOCKET_GID`, for example using `stat -c '%g' /var/run/docker.sock`, so the unprivileged `CODEMAN_RUNTIME_USER` account can create Docker cases. Docker Desktop users should set `DOCKER_SOCKET` in `docker/.env` only when their Docker installation exposes a different compatible socket path.
Codeman Docker cases are sibling containers on the host daemon, not children of the application container. The Compose configuration handles their workspace bind mount through `CODEMAN_CASES_PATH`; the `/home/${CODEMAN_RUNTIME_USER}` application-data mapping is for Codeman state and ordinary in-container sessions, not sibling-case workspaces.

# Self-update in the Docker Compose deployment
Codeman running as a container updates itself from **App Settings → Updates**, the
same place and the same button as a bare-host install. This document explains how
that works, what it deliberately refuses to do, and how to recover when it stops.
The bare-host updater is documented in
[`architecture-invariants.md#self-update`](architecture-invariants.md#self-update);
this file covers only what the container changes.
## The short version
| Change in the release | Applied by |
| -------------------------------- | ------------------------------------------------ |
| Application code | The in-app updater |
| `docker/server.Dockerfile` | `docker/Start-Codeman.sh` on the host |
| `docker/docker-compose.yaml` | `docker/Start-Codeman.sh` on the host |
| New key in `docker/.env.example` | Add it to `docker/.env`, then `Start-Codeman.sh` |
The in-app updater detects all three of the bottom rows itself and refuses with a
message naming what changed, so you never have to work out which case you are in.
## Why the container needs its own path
The bare-host updater does `git checkout <tag> && npm install && npm run build`,
then asks systemd or launchd to restart the service. Two of those assumptions are
false in a container:
1. **There is no init system.** A container's supervisor is the Docker daemon,
which acts on the container, not on processes inside it.
2. **The image is immutable.** A `git pull` into the image's baked `/opt/codeman`
would land in the container's writable layer, survive `docker restart`, and be
silently discarded by the next `docker compose up`.
Both are solved by configuration rather than by a second updater:
- **The checkout is a host bind mount.** `docker-compose.yaml` mounts the repo
(the same directory used as the build context) over `/opt/codeman`, so the
updater's `git checkout` writes to the host filesystem and survives the
container being recreated.
- **The restart is the server exiting.** `restart: unless-stopped` relaunches the
container whenever its main process ends, including on a clean exit — so the
updater's final step is to signal the server, and Docker starts it again on the
freshly built `dist/`.
Everything else — the release-tag channel, the auto-stash, the atomic
`update-status.json` the browser polls across the connection drop, the boot-time
reconcile that flips `restarting` to `completed` — is the existing machinery,
unchanged. The container path is a new `SupervisorKind`, not a new updater.
## What the pieces are
| Piece | Role |
| ---------------------------------------------- | ------------------------------------------------------------------- |
| Repo bind mount at `/opt/codeman` | Makes the pull persistent. Without it, self-update is unavailable. |
| `codeman-node-modules`, `codeman-dist` volumes | Container-owned build artefacts, layered over the bind mount. |
| `CODEMAN_IN_CONTAINER=1` | Tells `detectSupervisor()` to restart by exiting. |
| `restart: unless-stopped` | Turns that exit into a restart. Verified before every update. |
| `CODEMAN_RESTART_BY_EXIT=1` | The Compose file's declaration of that policy, so the updater may exit even with no Docker socket. |
| Toolchain + devDependencies in the image | Lets `npm install` and `npm run build` run inside the container. |
| `docker-env-applied.json` | Fingerprint baseline, written by `Start-Codeman.sh` on every start. |
### Why build artefacts are in named volumes
`node_modules` and `dist` are mounted as named volumes **on top of** the repo bind
mount. Without that, an update's `npm install` would write into the host checkout,
leaving container-compiled native modules (node-pty builds from source here) in a
directory that may also be used to run Codeman natively, and leaving `git status`
permanently noisy.
Docker seeds an empty named volume from the image, so the first start inherits the
image's already-built `node_modules` and `dist` and pays no bootstrap cost.
`docker compose down -v` is the supported reset: the next start re-seeds them.
### Why the runtime image carries a build toolchain
`npm run build` is `tsc` plus `esbuild`, both devDependencies, so the image no
longer runs `npm prune --omit=dev`. And `npm install` may rebuild node-pty, which
ships no Linux prebuild, so `python3`, `make` and `g++` are installed as well.
This is the real cost of in-place updates: a noticeably larger image than a
runtime-only one. It buys an update that takes about a minute instead of a full
image rebuild, and it is why `NODE_ENV=production` is paired with an explicit
`npm install --include=dev` in the updater.
## The environment gate
An in-place update applies **code only**. A restarted container reuses its existing
image and configuration, so a release that changes the environment cannot take
effect that way — and would half-apply: new code against an old environment. The
updater therefore checks the **target release's own files**, read straight out of
git with `git show <tag>:<path>` before anything is checked out.
### 1. `server.Dockerfile` changed, so the image must be rebuilt
Compared by sha256 against the fingerprint `Start-Codeman.sh` recorded when the
running container was built.
### 2. `docker-compose.yaml` changed, so the container must be recreated
Same mechanism. A restart cannot pick up a new mount, port or environment
variable; only recreating the container can.
### 3. `.env.example` gained keys your `.env` has no value for
The check that matters most, because **Compose will not tell you**. An unset
`${VAR}` interpolates to the empty string; Compose prints a warning to a terminal
nobody is watching and starts anyway. A new required setting therefore arrives as
a silently blank environment variable and misbehaves later, far from the cause.
The updater names the missing keys instead.
Commented-out lines in `.env.example` are deliberately *not* keys — that is how
the file marks optional overrides such as `# PUID=1000`, and counting them would
block updates on settings you are meant to leave alone.
### 4. A restart policy that would not bring the container back
Before signalling the server, the updater asks the Docker daemon for its own
container's restart policy. If it is `no`, the update is refused: applying it
would take Codeman down and leave no UI to recover from.
If the policy cannot be read at all (no Docker socket mounted) the update is
still allowed, but the final step changes: the server exits only when the
Compose file declared `CODEMAN_RESTART_BY_EXIT=1` (the shipped one does, because
it is the file that sets `restart: unless-stopped`) or the daemon confirmed an
auto-restart policy. Otherwise the build completes and the panel asks you to
restart the container by hand. A container started by plain `docker run` with no
restart policy therefore gets a staged update, never an outage.
### What the gate deliberately does not do
Every unknown fails **open**:
- A missing fingerprint baseline (a container started before this feature existed)
is not treated as a change, or those installs could never update at all.
- An unreadable `.env`, an unreachable Docker socket, or a target tag whose files
cannot be read all yield "no blocker" rather than a refusal.
The one place an unknown does NOT fail open is the kill itself: with neither the
Compose declaration nor a daemon answer, the updater stages the build and asks
for a manual restart rather than exiting a server nothing may bring back.
The gate catches a specific, detectable class of mistake; it is not a last line of
defence. It is also re-evaluated server-side on `POST /api/system/update`, so
hiding the button in the UI is a courtesy rather than the control.
## The one residual risk
The gate is derived from the diff, so it cannot see a release that needs a newer
environment **without changing any of those files** — for example, code that
depends on newer agent-CLI behaviour.
That is why the four global CLIs in `server.Dockerfile` are **pinned**. Unpinned,
the versions a user ends up with are a function of when their image was built
rather than of any commit, and in-app updates make rebuilds rarer, which makes
that drift worse over time. Pinned, "this release needs a newer CLI" becomes a
Dockerfile change, which check 1 already detects. Bump them deliberately, as part
of a release.
The complementary merge-side guard is `test/docker-compose-env-parity.test.ts`,
which fails CI when a variable is added to `docker-compose.yaml` without an entry
in `.env.example`, or the reverse.
## Sequence of an in-place update
1. **Check** — `GET /api/system/update/check` finds the latest release tag, fetches
that one ref so the gate can read the target's files, and returns any blockers.
2. **Start** — `POST /api/system/update` re-evaluates the gate, writes `queued` to
`update-status.json`, stages `self-update.sh` outside the repo and runs it.
3. **Apply** — stash if dirty, fetch the tag, check it out, `npm install
--include=dev`, `npm run build`. A failure at any step rolls back to the
previous commit, rebuilds it and reports `failed`; the server is never
restarted into a broken build.
4. **Restart** — write the terminal `restarting` marker, then signal the server.
The container exits and Docker restarts it.
5. **Reconcile** — the rebooted server compares its own version against the target
and flips the status to `completed` or `failed`. The browser, still polling,
picks that up.
Step 4 kills the updater script along with the container — unlike the systemd
path, it does not outlive the restart. That is safe only because the terminal
marker is written first, which is why nothing may be appended after the kill.
## Troubleshooting
**"This install can't update itself (unknown)"** — the repo bind mount is missing,
so the container is running the baked image copy. Check `CODEMAN_REPO_PATH` and
confirm the mounted directory really contains `.git`.
**The update fails immediately with a git ownership or permission error** — the
mounted checkout belongs to a different user than the one Codeman runs as
(`PUID`), so git refuses it as "dubious ownership". `Start-Codeman.sh` warns
about this at start; fix it by chowning the checkout to the same account that
owns `CODEMAN_APPDATA_PATH`.
**A rebuild is reported as required every time** — the fingerprint baseline does
not match the checkout. `Start-Codeman.sh` writes it on every start, so start
through that script rather than a bare `docker compose up` after either file
changes.
**Codeman does not come back after an update** — the build succeeded, since the
updater gates the restart on it, so read the container logs with `docker compose
logs codeman`. To roll back, check out the previous tag in the host checkout and
run `docker/Start-Codeman.sh`.
**The update failed during `npm install`** — most likely a native rebuild with no
toolchain, meaning the image predates the toolchain being added. Rebuild once from
the host and the in-app path works from then on.
**Resetting the build artefacts** — `docker compose down -v`, then
`Start-Codeman.sh`. This discards the named volumes and re-seeds them from a fresh
image.
## Disabling it
Set `CODEMAN_DISABLE_SELF_UPDATE=1` in `docker/.env` and pass it through in the
compose file's `environment:` block. The Updates panel then reports that in-app
updates are disabled, and the host-side script is the only way to update.

# OMP (Oh My Pi) sessions
Codeman can drive [OMP](https://github.com/can1357/oh-my-pi) (`omp`, Oh My Pi) as a session
backend, alongside Claude Code, OpenCode, Codex, Gemini, Antigravity, Pi, Grok and
DeepSeek Harness. `omp` is the ninth CLI backend (tenth `SessionMode`, counting
`shell`): its own PTY, its own tmux session, its own tab identity. It is not a
location overlay like Docker or remote-SSH cases, and it is not a web tab.
## Install
```bash
curl -fsSL https://omp.sh/install | sh
```
The installer places the binary in `~/.local/bin` (verified against a real
`--no-cache` Docker build — see `docker/agent.Dockerfile`; an earlier guess of
`~/.omp/bin` was wrong). Codeman resolves the binary via the server PATH and then
the usual install locations (`~/.local/bin` first, then `~/.omp/bin`,
`/usr/local/bin`, `~/.bun/bin`, `~/.npm-global/bin`, `~/bin`).
**`omp` is a short name**, so like `pi` and `grok` the resolver does not trust a PATH
hit on its own: it runs `omp --version` and requires `omp/<semver>`-shaped output
(e.g. `omp/18.0.8`) before accepting a candidate. Check what it resolved:
```bash
curl -s localhost:3000/api/omp/status | jq
# { "available": true, "path": "/home/you/.local/bin", "version": "18.0.8" }
```
## Authenticate
OMP owns its own auth and provider configuration entirely in `~/.omp` — there is
no Codeman-side login flow, API key field, or bypass switch to configure. Run `omp`
directly once outside Codeman to complete whatever onboarding the CLI itself asks
for; every session started through Codeman afterward inherits that config.
## What Codeman wires up
`OmpConfig` (per session, persisted in `state.json`, round-trips through respawn):
| Field | Flag | Notes |
| ------------------ | --------------- | ---------------------------------------------------------- |
| `model` | `--model <v>` | Regex-validated (`[a-zA-Z0-9._-/]+`); `provider/model` forms like `crof/glm-5.2` pass |
| `continueSession` | `--continue` | omp's own "most recent conversation in this directory" heuristic |
| `resumeSessionId` | `--resume <id>` | Ids only, id-regexed; wins over `--continue` when both are present |
Every value is regex-validated and **dropped** (not escaped) if it fails, because the
result is interpolated into the pane's spawn command.
**omp reads its own model routing and hooks from `~/.omp`, so no trust or
permission flags are needed** — unlike every sibling CLI in this family, there is no
bypass-permissions equivalent to wire up, so `buildOmpCommand()` only ever passes
`--model`/`--resume`/`--continue`. ⚠️ That does NOT mean omp is unrestricted: its
documented default `tools.approvalMode` is `yolo`, so an omp pane auto-approves exec
with no flag from Codeman — the CLI's own config, not Codeman, is what would need to
change that.
Env overrides: the `OMP_*` prefix is allowlisted, and per omp's own
`docs/environment-variables.md` it is not the narrow surface it looks like. omp reads
roughly 40 provider keys from the environment (`ANTHROPIC_API_KEY`, `OPENAI_API_KEY`,
`XAI_API_KEY`, `HF_TOKEN`, ...) — pi's 34-key problem in the same shape — which is why
none of those get a dedicated allowlist entry; a session authenticates from `~/.omp`
config or the server process's own env instead, like pi. omp's own documented knobs
are mostly `PI_*`, not `OMP_*` (`PI_CONFIG_DIR`, `PI_CODING_AGENT_DIR`,
`PI_CODING_AGENT_SESSION_DIR`, `PI_SUBPROCESS_CMD`, `PI_SHELL_PREFIX`,
`OMP_PROFILE`/`PI_PROFILE`), and `PI_*` is already allowlisted globally because pi
mode needs it — so an omp session today already accepts all of those. The first three
also move the tree `omp-session-resolver.ts` and `omp-transcript.ts` hardcode
(`resolveOmpHome()` assumes `~/.omp` unconditionally), so pinning and history quietly
stop working under a redirected config root; this is a known gap, not fixed here.
The `OMP_` prefix itself brings in `OMP_AUTH_BROKER_URL` / `OMP_AUTH_BROKER_TOKEN`,
where omp resolves credentials from — the same shape `DEEPSEEK_BASE_URL` is dropped
for in `clampEnvOverridesForOwner()` (session-routes.ts), so both are clamped there
for a non-granted owner in multi-user mode. None of this matters in single-user mode.
## Exact-id pinning: why `--resume`, not just `--continue`
`--continue` alone is ambiguous the moment **any** other omp conversation has
touched the same working directory more recently — it just picks the newest session
file on disk, silently. That happens routinely: a closed-then-resumed Codeman row
plus a still-running duplicate, two Codeman sessions pointed at the same case, or a
plain reattach after a server restart.
`src/utils/omp-session-resolver.ts` resolves and **pins** the exact conversation id
once (`findLatestOmpSessionId()` reads `~/.omp/agent/sessions/<mangled-workingDir>/`,
the newest `.jsonl` file's embedded uuid), then every later respawn reuses that
pinned id via `--resume` instead of re-guessing with `--continue`.
⚠️ **The directory mangling is NOT a straight `/` → `-` replace.** Unlike Claude
Code's `~/.claude/projects/*` convention (which keeps the full path, e.g.
`-home-user-codeman-cases-foo`), omp strips the `$HOME` prefix FIRST and only then
dash-replaces (`/home/user/codeman-cases/foo` → `-codeman-cases-foo`; a path outside
`$HOME`, like `/tmp/...`, is dash-replaced as-is with no stripping). Getting this
wrong doesn't error — `findLatestOmpSessionId()` just silently returns null for
every case under `$HOME` (virtually all real Codeman cases), so pinning quietly
degrades to omp's own ambiguous `--continue`. This was found and fixed 2026-08-27
after months of testing had only ever exercised `/tmp`-based working directories,
where the bug's wrong output happened to coincidentally match the right one.
## Surviving a full session kill
`src/omp-transcript.ts` scans `~/.omp/agent/sessions/**/*.jsonl` directly — a second,
independent history source alongside Codeman's own state. This means an OMP
conversation's history (working directory, first/last prompt, size) is recoverable
in the Past Sessions list even when **both** the Codeman session record and the
underlying tmux pane are gone — verified live against a full OS reboot, not just a
"Kill Tmux" button click.
## Terminal behavior
OMP renders inside tmux like every external CLI (narrow scrollback strip — alt-screen
toggles only, not the full Claude/Codex/Gemini strip). It stays out of the
alt-screen-strip list and lands on the `'buffer'` local-echo policy via the
`_updateLocalEchoState` fallthrough, same as grok and pi.
## Docker cases
The agent image installs omp in its own Dockerfile step (not npm; omp's installer
targets `$HOME/.local/bin` with no `--dir` override, the same shape as grok's
installer). Rebuild with the mandatory `--no-cache`:
```bash
node scripts/build-agent-image.mjs --no-cache
```
⚠️ **`--resume` pinning does not currently reach an in-container omp process.**
Docker panes are built from `defaultDockerCommandForMode`, which never sees
`ompConfig` — `appendResumeFlag()`'s `case 'omp'` keys off the top-level
`resumeSessionId` field, which nothing populates for omp today. Host-side history
recovery still works (the shared `sessions/` mount below), but a respawned
in-container omp pane falls back to its own ambiguous `--continue`, not a pinned
id. Flagged in upstream review, not yet fixed.
Credentials are **mostly seeded**, but `sessions/` is the one exception in this CLI
family: `~/.omp/agent/{config.yml,mcp.json,models.yml,settings.yml}` are seeded
(read-only mount, copied into the container's own `~/.omp/agent` once), so an
in-container omp never writes refreshed config back to the host and `docker commit`
exports stay secret-free. But `~/.omp/agent/sessions/` is **shared (RW)**, not
seeded — the same treatment as codex's `sessions/`, and for the identical reason:
Codeman reads it host-side (`omp-transcript.ts`, `omp-session-resolver.ts`) for
history recovery and `--resume` pinning. Seeding it instead of sharing it would make
an in-container OMP conversation invisible to Codeman's own history/resume logic,
silently breaking Docker support for the kill-survival feature above. The rest of
`~/.omp/agent` (`agent.db`/`history.db`/`models.db` SQLite caches,
`terminal-sessions/`, `blobs/`, `cache/`) stays container-local and is neither
shared nor seeded.
## Remote SSH cases
`omp` mode is routed through an interactive login shell
(`exec "$SHELL" -i -l -c 'omp'`), because sshd's remote-command PATH does not
include `~/.local/bin`. Per-session config and `envOverrides` do not cross ssh and are
rejected rather than silently ignored; use the per-host command override instead.
## Known gaps
- **No idle/completion hook.** Idle detection falls back to output-stabilization
like every other external CLI. If omp ever ships a hooks system, a Codeman hook
POSTing to `/api/hook-event` would be the highest-value follow-up.
- **Killing a pane mid-turn loses the conversation for real.** `tmux kill-session`
before an in-TUI `/exit` beats omp's own session-file flush — confirmed by direct
testing (kill after a clean `/exit` resumes correctly; kill without `/exit` first
does not). This is not something Codeman can compensate for from outside the
process; it would need an upstream omp fix (e.g. flush-on-SIGTERM).
- **Unverified: `$HOME` as a symlink.** The directory-mangling fix above compares
against the literal `homedir()` string, not a `realpath()`-resolved one. Whether
omp itself canonicalizes symlinks before mangling is unconfirmed — this has not
been tested against a symlinked-home setup.
- Ralph, respawn heuristics, token/CLI-info parsing and the `❯` readiness probe are
off for omp, as for every external CLI.
