Custom Model Endpoint Profiles (#393) let a session point its CLI at a
custom OpenAI-compatible endpoint by injecting env vars or a config file
and restarting the CLI in place. Review of the apply path found four
things, two of them destructive. This lands all four plus the smaller
items from the same review.
1. Clearing a selection did not clear it. The injected vars reach the CLI
via `tmux setenv`, which persists at the tmux-session level and is
inherited by `respawn-pane` (measured: `setenv FOO bar` survived two
successive `respawn-pane -k`), so deleting the keys from the session's
envOverrides relaunched the CLI still pointed at the old endpoint, and
for the configDir kinds at a HOME/CODEX_HOME/GROK_HOME that had just
been deleted. `Session.setCustomModel()` now reports the removed keys,
queues them (`_pendingEnvUnsets`), and `RespawnPaneOptions.unsetEnvKeys`
carries them into `applyEnvOverrides()`, which `setenv -u`s them before
re-applying the live overrides, on the same path that already unsets
the legacy CLAUDE_CODE_EFFORT_LEVEL. Verified on a private tmux socket
that `setenv -u HOME` hands the next respawn the global HOME back.
2. Applying a model to a local claude session killed the pane. The
relaunch was `claude --session-id <id>` and Claude refuses an id that
already has a transcript, and unlike the dead-pane respawn this one
kills a working pane first. `restartCli()` now pins the live
conversation id as the resume id for that respawn when the CLI's launch
declares a `fallback` chain, which renders the same
`--resume <id> || --session-id <id>` shape the docker and remote pane
commands use. Gated on the registry shape, not the CLI id: an entry
whose resume id is minted by the CLI itself never declares that chain.
3. pi, omp and grok wrote their config file and then launched without the
`--model` that selects it, so the file was ignored. The registry entry
now declares `customModelInjection.launchModel` (`custom/{modelId}` for
pi and omp, grok's `[model.codeman-custom]` block name), the builder
renders it, and `_withCustomModelLaunchModel()` applies it onto the
respawn options through `legacyConfigField`, leaving the stored
<Mode>Config untouched so a clear falls back to the user's own model.
A model id the CLI's `model` token pattern cannot carry is refused
with a 400 rather than silently dropped by the argv engine.
4. Remote (SSH) and Docker sessions reported `restarted: true` and changed
nothing: their `restartCli()` reattaches the durable tmux rather than
relaunching the agent, and the env lands on the local pane. Both are
refused with a 400 until those paths are plumbed.
Smaller items from the same review:
- The selection survives a Codeman restart as the disk-only `__customModel`
bookkeeping (endpoint, model, injected key NAMES, config dir, launch
model; never the values, which carry the API key). Recovery re-derives
the values from the endpoint store through the same apply path the route
uses and keeps the bookkeeping even when the endpoint is gone, so a
later clear still has keys to unset.
- Discovery goes through `webviewFetch()`, so the RESOLVED address is
judged by the same egress guard the web-tab proxy uses, and `baseUrl`
reuses `webviewUrlSchema` (http(s) only, no embedded credentials,
link-local and cloud-metadata addresses refused). undici's `fetch failed`
wrapper is unwrapped so the user sees the ECONNREFUSED underneath.
- `custom-model-hosts.json` is written 0600 via tmp+rename, the per-session
config dir 0700/0600 (pi and omp embed the key literally), and that dir
is removed with the session.
- `PR.md` is gone from the repo root and the design doc moved to
`docs/custom-model-endpoints-plan.md` with the LAN address and the
personal name scrubbed; every reference follows. The guide's `authStyle`
text matches the shipped schema (`bearer | api-key`, default `bearer`)
and says that `customModelEndpointsEnabled` is read by nothing until
the picker lands.
- `config/tsconfig.scripts.json` typechecks `scripts/test-local-llm-harnesses.ts`
(four real type errors fixed). It is not yet wired into `npm run typecheck`
because that line differs on master; adding `&& tsc -p config/tsconfig.scripts.json`
there is the one-line follow-up.
Tests: `test/session-custom-model-restart.test.ts` drives a real Session and
fails on the unfixed code for items 1 to 3; the route suite covers item 4
and the pattern refusal; `test/tmux-manager.test.ts` pins that the unsets
run before the overrides and that a shell-metachar key never reaches tmux.

Resolved conflict in src/web/public/session-ui.js by keeping this
PR's buildEnvOverrides() helper — it already covers both
CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS (this PR) and
CLAUDE_CODE_EFFORT_LEVEL (added in #73), so the master-side inline
block is fully replaced.
Also fixed test/session-manager.test.ts MockSession to add a
getEnvOverridesForPersist() stub — without it,
SessionManager.updateSessionState's new call breaks 19 tests with
"TypeError: session.getEnvOverridesForPersist is not a function".
Verified: typecheck, lint, format:check, build, and
test/{session-manager,session-state,tmux-manager,tmux-restart-recovery}.test.ts
all pass.
