DevvynandClaude Sonnet 5 e2034177c5 fix(custom-model): root-cause and fix DeepSeek's HTTP_404 (missing /v1)
DeepSeek Harness's own bundled provider module
(@deepseek-ai/dsh-llm-deepseek) builds its request URL as
`${DEEPSEEK_BASE_URL}/chat/completions` with no `/v1` insertion of its
own (its real public API, https://api.deepseek.com, expects the
caller's base URL to already carry any needed prefix), while
llama-swap/llama.cpp only ever serves the OpenAI-conventional
`/v1/chat/completions`.

Confirmed two ways:
- Installed the real @deepseek-ai/dsh package (all its actual
  published dependencies) into a scratch dir purely to read
  dsh-llm-deepseek's source: `fetch(`${connection.baseURL}/chat/
  completions`, ...)`, baseURL read straight from DEEPSEEK_BASE_URL —
  the same grep-the-real-source bar pi/grok's fixes were held to.
- Live against the test-picker's llama-swap: `POST <baseUrl>/chat/
  completions` -> 404, `POST <baseUrl>/v1/chat/completions` -> 200,
  same endpoint. dsh's own error template ("DeepSeek API error (HTTP
  ${status})") reproduces the originally-reported
  "dsh: HTTP_404: DeepSeek API error (HTTP 404)" exactly.

- New registry field `appendV1Suffix` (env kind only, deepseek's entry
  alone — claude/gemini must NOT get it, since claude was already
  confirmed working against the unmodified baseUrl). When set,
  buildCustomModelInjection runs endpoint.baseUrl through the same
  withV1Suffix() helper configDir-kind CLIs (pi/grok/codex) already
  use, instead of writing it verbatim.

Not yet re-run end-to-end through a real dsh binary — no install
available in this environment (not in PATH, and the test-picker
container doesn't bundle it) — so this is source-confirmed and
live-verified at the HTTP level, not yet promoted to "verified"
alongside claude/opencode/pi/grok/omp. Docs (custom-model-endpoints.md,
the plan doc's confidence table, the wiki page, CLAUDE.md) all updated
to reflect this precisely rather than leaving the old "root cause not
identified" claim in place.

2 new/updated tests for the /v1 suffix (including idempotency against
a baseUrl that already ends in /v1) plus a corrected mock-server
contract test. Typecheck/lint clean; full suite shows no new
regressions.

DevvynandClaude Sonnet 5 8520925e76 docs(custom-model): bring CLAUDE.md and api-reference.md up to date
Full documentation review pass across the branch's 30 commits.
CLAUDE.md's Custom Model Endpoint Profiles entry hadn't been touched
since the initial backend+picker cut (3 early commits) despite 27
follow-up commits adding real behavior — it described restart-in-place
as universal (now claude-only; 7 other CLIs launch one-shot) and
claimed codex's Responses-API gap as a flat protocol break (now
re-verified as a more precise tool-calling gap). Corrected both and
added a new paragraph covering everything landed since: the llama-swap
conflict check, the after-the-fact swap-displacement sweep, the
/running-cmd-based context-length fix, the context-window floor
warning, skipFirstRunPrompts, the real-time /api/events-based log
status, and the countdown-to-Cancel-button change.

docs/api-reference.md's custom-model-endpoints section was missing the
running-status route, the requiresConfirmation/requiresContextWarning
response shapes, and POST /api/quick-start's customModel field
entirely (the primary launch path for 7 of 8 supported CLIs) — added
all three. Also fixed a real markdown bug in custom-model-endpoints.md:
an inline code span (`POST <baseUrl>/v1/chat/completions`) split across
a line break, which CommonMark renders with the line ending collapsed
to a space, so it displayed as ".../v1/chat/ completions" with a
spurious space inside the path.

Verified: origin/master and upstream/master are both already an
ancestor of this branch (identical at bd286bf5, no new commits since
this branch was cut) — nothing to merge, no conflicts.

DevvynandClaude Sonnet 5 470f75b08c docs(custom-model): record live findings on codex's model-metadata warning
Investigated the user's report of "Model metadata for <id> not found.
Defaulting to fallback metadata..." on every custom-endpoint codex
launch, live against the test-picker's llama-swap deployment (codex
0.152.1):

- The warning is cosmetic. `codex exec 'reply with just OK'` against the
  isolated CODEX_HOME still printed the warning and still returned a
  real reply.
- The isolated CODEX_HOME never gets a models_cache.json written into
  it at all, even after extended real use (inspected a live, actively-
  used directory) — codex can't reach OpenAI's own hosted model catalog
  for this session and silently falls back every time, with no local
  file to create or clean up. There is also no config.toml override for
  a model's metadata.
- Fabricating a fake catalog entry to suppress it would mean copying the
  SHAPE of OpenAI's own proprietary models_cache.json schema, including
  real per-model system-prompt content visible in a genuine entry — not
  something to build for a warning confirmed to have no effect.
- More importantly: a real tool-call attempt against the same setup came
  back as agent_message TEXT (the tool-call JSON printed as the answer)
  rather than an executable function_call item, confirmed via
  `codex exec --json`'s raw event stream. Tool execution is what makes
  codex a coding agent, so it remains not usable for real work regardless
  of the metadata warning — a more precise, re-verified update to the
  existing "Responses API protocol gap" finding (which reported a harder
  Reconnecting/high-demand failure on a different llama-swap deployment;
  this one answers /v1/responses for plain chat but still can't execute
  tools).

No code changes — recipe/comment/confidence-table documentation only.

DevvynandClaude Sonnet 5 60e1bd52f7 fix(custom-model): act on the draft review — unparseable onclick, unwrapped envelope, wrong-session apply, missing lock, no tests
Addresses every blocker, both majors, and all but one minor from the
maintainer's review of the draft PR.

Blockers:

1. Every generated inline onclick was unparseable. JSON.stringify's own
   double quotes terminated the double-quoted HTML attribute at the first
   one, leaving btn.onclick null on every picker entry and every Discover/
   Edit/Delete button. Fixed with escapeHtml(JSON.stringify(...)) per
   argument, the same idiom deleteCase's onclick already uses four lines
   away in session-ui.js. This also closes the live-HTML-injection route
   through modelId (server-controlled, from the endpoint's own /v1/models
   reply): with quoting intact, a `>` inside it can no longer terminate the
   <button> tag early.
2. GET /api/model-endpoints wraps its body in the {success,data} envelope
   like every other /api route (server.ts's preSerialization hook applies
   to arrays too), so Array.isArray(hosts) was always false in production
   and the picker/settings panel silently saw nothing. Both call sites now
   go through _apiJson(), which already exists for exactly this.
3. A failed or declined run*() (missing CLI, isBusy, a caught exception)
   returns normally without ever changing activeSessionId, so the apply
   step used to silently re-point and restart whatever session the user was
   already looking at. runCustomModelEntry() now snapshots activeSessionId
   before the launch and requires it to have actually changed.

Majors:

4. Routes the launch through run() itself via a temporary _runMode swap
   (never persisted — setRunMode() would sync it to the server) instead of
   a parallel hardcoded dispatch table, so a custom-model launch now holds
   the same _runInFlight lock every other Run click gets. This also
   resolves the "hardcoded runners map contradicts the PR's own design"
   minor: dispatch is run()'s own, so a CLI whose customModelInjection
   recipe lands later needs no update here.
5. New test/custom-model-run-menu-ui.test.ts drives the real session-ui.js
   against a JSDOM window (runScripts:"dangerously" — this JSDOM only ever
   parses markup this module generated itself) for exactly the DOM-level
   facts the review said needed no Playwright and no tmux: a generated
   button's onclick genuinely compiles and fires, a dangerous modelId never
   produces a live element, the envelope unwrap works, the session-changed
   guard holds, run() actually gets called (proving the in-flight lock
   engages), and _runMode is restored afterward. Confirmed against the
   pre-fix code first (reproduces btn.onclick === null exactly) so this
   isn't a vacuous pass. Plus new tests in custom-model-routes.test.ts and
   render-index-html.test.ts for the other fixes below.

Minors:

- Generated entries now filter through isCliAvailable(), matching
  _refreshRunModeAvailability's own gating of the stock entries.
- The CRUD panel is now gated on customModelEndpointsEnabled
  (applyCustomModelEndpointsVisibility(), wired to the toggle's onchange
  and to settings-modal open) instead of always rendering; the endpoint GET
  no longer fires unconditionally either.
- API keys are never handed back to the browser on GET, POST or PUT —
  redactApiKey() replaces the field with a computed apiKeySet: boolean, and
  a PUT with no apiKey now keeps the stored one server-side
  (applyStoredApiKey()) instead of the client resending a value it was
  never given. New tests cover both directions (kept vs. replaced) by
  observing the actual auth header a subsequent discovery request sends.
- "+ Add endpoint" hides for a non-admin in multi-user mode
  (_applyCustomModelAdminGate(), also wired to admin-ui.js's codeman:me
  event, since the real role can resolve after settings were first opened)
  — endpoint writes were already admin-only server-side, but the button
  used to render for everyone and eat a 403.
- design doc (custom-model-endpoints-plan.md §4) now says up front that its
  toolbar-button design was superseded by the Run-menu picker.
- docs/api-reference.md gained a Custom Model Endpoints section (every
  route, the apiKeySet/defaultModelId contract, the restart mechanics).
- Wiki page now covers un-pointing a session (curl/delete, no UI yet) and
  that the picker is desktop-only for now.
- .set-inline-form uses --control-bg instead of a hardcoded black alpha
  (CLAUDE.md already records that exact literal turning the settings
  preview into a grey slab on light skins), .run-mode-custom-models gets
  the same gap: 2px .run-mode-menu's own flex gap only applies one level
  up, and the index.html comment naming the wrong function is fixed.
- __codemanCustomModelClis's JSON is now escaped against a literal
  </script> (CliEntry.label is user-clis.json-settable, unlike
  __codemanCliAvailable's booleans-only payload) via a new exported
  escapeScriptJson(), pure and unit-tested without needing a WebServer.
- Added defaultModelId + the new /v1/model-endpoints routes to
  docs/api-reference.md; left the "no zh-CN for the new Models-section
  group" minor unaddressed only insofar as the wider Models section (task
  routing, thinking effort, etc.) has never had zh-CN coverage either —
  everything this PR itself introduces (labels, hints, button text, the
  Run-menu's "Custom Endpoints" header) IS translated in i18n.js.

Regression caught while fixing #4: the admin-gate's codeman:me listener is
a module-level document.addEventListener() call, which threw in
run-mode-ui.test.ts's minimal vm-context fake document and failed all 10
of that file's tests. Fixed with optional chaining before it ever reached
the branch this commit lands on; full targeted suite (route tests,
structural guards, every settings-ui.js-loading frontend test) reverified
green afterward.

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.
