Michael GrundbergandClaude Opus 5 1cb0441bd8 fix(session): degrade the resume pin to the session id, not to nothing
A single pin that failed its transcript gate returned the options untouched,
so `resumeSessionId` fell back to `_resumeSessionId` — undefined for an
ordinary session — and the renderer emitted the bare
`claude --dangerously-skip-permissions --session-id "<this.id>"`. Every
session prompted before its first `/clear` owns a transcript under that id,
so the dropped pin handed back exactly the refusal this branch removes, with
no `||` branch to catch it. It was also a regression against master on the
`restartCli()` path, which pinned `_claudeSessionId ?? this.id` and, since the
constructor seeds that field, could never land unpinned.

The pin now walks three candidates in priority order — the conversation
chain's tail, the launch seed, then the session's own id — and takes the first
one a transcript backs. A candidate that misses is passed over rather than
ending the walk.

Falling off the end pins nothing, which also settles the second half of the
problem: the old code skipped the transcript check whenever the pin was the
session's own id, so a genuinely new pane rendered the two-branch form after
all. That costs a brand-new session claude's "No conversation found" line in
its scrollback, and `wrapWithNice()` prefixes only the first branch of the
rendered `a || b`, so the branch that actually runs loses its priority for the
life of the session. With no transcript anywhere the bare `--session-id` is
the correct command, so the comment claiming an unchanged shape is now true.

The transcript lookup reads the server process's own `CLAUDE_CONFIG_DIR` when
a session declares none. A pane inherits the server environment through tmux,
so on an install that exports it the CLI writes its transcripts there and
every lookup under `~/.claude` was a false negative — which under the old code
meant the colliding command. `claudeCredentialsPath()` and
`realClaudeConfigDir()` resolve the same directory the same way. The header
sentence calling a skipped resume "the safe direction" described the opposite
of what happens at this call site, and says so now.

The create-path fallback writes `_resumeSessionId` alongside the create
options. That branch leaves `isRestored` false, so `_claudeSessionId` is
recomputed from the launch fields and settled on `this.id` while the CLI
resumed the chain tail; the response viewer, Read My Mind and the unified-list
alias map read that field until the next first-hand hook.

Four new tests: a chain tail with no transcript while the session id has one,
no transcript anywhere, the create path's alias, and the process-env lookup.
All four fail against the previous commit. Two existing tests move with the
gate — the guess-refusal test now backs the session's own id, and the
custom-model restart test gives its working pane the transcript that makes
`--session-id` collide in the first place, alongside a new one pinning the
no-transcript case.

CLAUDE.md described the pin as a `restartCli()`-only thing sourced from the
live conversation id. All three halves of that moved here.

Codeman maintainer 942bf37e48 fix(custom-model): unset injected env on clear, resume on restart, select the model for pi/omp/grok
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.
