Codeman maintainer 02b0e27898 fix: merge-time follow-ups for #400, #401, #362 and #388
Each item is from the pre-merge review of the PR it names, applied on master
rather than by pushing to a contributor branch.

#400 (response viewer, shenlvkang-collab)
- The brief view opened at `scrollTop = 0`, right when it was a single card
  holding the last row. Now that it renders the whole turn, the top is the
  turn's first narration line and the answer can be screens below it, while
  loadFullContext already scrolls to the bottom of the same turn. A multi-row
  turn now opens at its newest text; a single card still opens at the top.

#401 (loopback links as web tabs, shenlvkang-collab)
- Drop `*.localhost` from the auto-route set. Every other member is an address
  literal that can only mean this box; a `*.localhost` DNS name is not one, and
  a resolver with a search domain retries `evil.localhost` as
  `evil.localhost.<search domain>`. The link source is agent-written terminal
  output, so that set is the whole confinement on a tap that makes Codeman
  fetch a URL server-side and persist it. The page-side test stays broader
  (`isOnBoxHostname`), where a false positive only declines to proxy.
- A link to the origin root navigated nothing: the path was flattened to '',
  which openWebview reads as "no deep link", leaving an open frame where it was.
- `this.webviews` being set does not mean it is loaded. initWebviews() assigns a
  truthy empty map and only then awaits the list, so a tap during page load
  found nothing to reuse and POSTed a duplicate record. Join the in-flight
  refresh instead.
- One dashboard per dev server rather than per host spelling, which is what the
  method's own comment already promised.
- Toast on the auto-create: it writes webviews.json, broadcasts over SSE and
  adds a Run-dropdown row on every signed-in device, with a new tab as its only
  previous signal.

#362 (remote omp continuation, timkjr)
- Accept the allowlisted `mode === 'omp'` arm as-is; a blanket registry render
  would hand deepseek a locally-resolved --profile and bypass claude's own
  overlay. A registry-declared switch is the follow-up if a third mode needs it.
- Revert the whole-file Prettier reformat of docs/remote-sessions.md (docs/ is
  hand-formatted and outside `npm run format`), keeping only the two new
  sections.
- Correct three stale passages: architecture-invariants' `exec claude
  --dangerously-skip-permissions`, the `exec <cli>` paragraph (claude and omp
  now have their own arms, and the claude pane's PID is the login shell), and
  omp-integration's `-c 'omp'`. RemoteCommandMode gains deepseek and omp.
- Add the missing `_maybeCaptureOmpSessionId` remote-guard test; the sibling
  guard in `_pinOmpRespawnId` had one and this path runs earlier, on the first
  idle turn.

#388 (keyCode 229 recovery, aakhter)
- Gate notifyCanonicalData on shouldSuppressTerminalQueryResponse and
  isTerminalFocusOrMouseReport. onData also carries the DA/DSR/CPR/OSC replies
  xterm answers during Ink redraws and its SGR mouse and focus reports; any of
  those landing between the keydown and the candidate's resolution was read as
  "xterm spoke for this keystroke", standing the recovery down and leaving the
  character dropped, worst on a busy agent pane. Reached through
  window.CodemanTerminalInput: the predicates live in a module IIFE that closes
  long before this call site, so bare references would throw into the
  surrounding try/catch and stop the notify from ever running.

Every fix has a test that fails without it (verified by reverting each).
Full gate green on the combined tree: 358 files, 6849 tests.

# 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 "$SHELL" -i -l -c 'omp'`), because sshd's remote-command PATH does not
include `~/.local/bin`. Per-session config and `envOverrides` do not cross ssh and are
rejected rather than silently ignored; use the per-host command override instead.
⚠️ A **respawn or reattach** of a remote omp session runs `omp --continue`, not a
bare `omp`, so it lands back in the same conversation. It is deliberately
`--continue` rather than the exact `--resume <id>` the local and docker paths
pin: `omp-session-resolver.ts` only ever reads THIS host's `~/.omp/agent/sessions/`,
and a remote conversation's session file lives on the remote host under the
remote user's home, so resolving locally would pin a stranger's id. See
[Respawn / reattach continuation](remote-sessions.md#respawn--reattach-continuation).
## Known gaps
- **No idle/completion hook.** Idle detection falls back to output-stabilization
like every other external CLI. If omp ever ships a hooks system, a Codeman hook
POSTing to `/api/hook-event` would be the highest-value follow-up.
- **Killing a pane mid-turn loses the conversation for real.** `tmux kill-session`
before an in-TUI `/exit` beats omp's own session-file flush — confirmed by direct
testing (kill after a clean `/exit` resumes correctly; kill without `/exit` first
does not). This is not something Codeman can compensate for from outside the
process; it would need an upstream omp fix (e.g. flush-on-SIGTERM).
- **Unverified: `$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.
