Codeman maintainer 4205f6930f fix(release): the seven findings from the pre-release review of the whole tree
A full review of the release tree found seven things, and four of them were mine.

**The gate was red, and I put it there.** Splitting `confirmed` into `confirmedContext`
and `confirmedSwap` changed the wire field without moving three assertions that check
it: `custom-model-one-shot-launch.test.ts` and two in `custom-model-run-menu-ui.test.ts`
(the swap modal and the context modal, each of which already receives exactly the right
per-question flag). Moved, with the titles.

**Worse, my own tests for the split never ran.** The four cases in
`session-custom-model.test.ts` that exist specifically to pin it call `mockRunning()`,
which was declared inside a sibling `describe`, so they threw a ReferenceError during
setup. The split would have shipped with no passing server-side coverage while the gate
reported the failure as four broken tests rather than as four tests that were never
written. `mockRunning` is hoisted to the outer describe.

**The submit verifier pressed Enter into shell panes.** `#455`'s SubmitVerifier resolved
its composer glyph as `promptGlyph ?? '❯'`, and only claude and codex declare one, so
the other eight modes fell back to claude's `❯`. That is also starship's default shell
prompt, and pure's, and spaceship's, and p10k lean's. On such a shell the line
`❯ npm run build` sits on screen for as long as the command runs, the verifier reads it
as an unsubmitted prompt, and re-presses Enter into the running program's stdin up to
nine times on its 2s..60s schedule. Mostly a stray newline; not harmless against a y/N
prompt, `read -p`, an installer or a pager, where it takes the default. The module's own
fileoverview already stated the rule this broke. Now `?? ''`, which
`promptStillInComposer()` already treats as inert, so the verifier runs only for a CLI
that actually declares a composer.

**My #451 dedent removal left a count behind**: "Two rules keep it honest" introducing
three numbered rules.

The rest is documentation the split outran. `confirmedContext`/`confirmedSwap` appeared
in no doc at all, while `docs/api-reference.md` (the SemVer-covered contract) still told
an integrator to retry with `confirmed: true` for both questions, which is precisely the
thing the split exists to stop. Documented there, in `docs/custom-model-endpoints.md`
and in CLAUDE.md. The custom-model changeset gained the split and the `CLAUDE_CONFIG_DIR`
multi-user consequence, both user-visible and both previously absent, and #454's gained
the one exception to its own claim: a Custom Endpoints launch ignores the Instance count
stepper and always starts one session.

Codeman maintainer fe3bd0074c fix(custom-model): split the two confirmation questions, and seed the API key the way claude reads it
Two findings from the review of 5fc391a4, both fixed here rather than sent back.

**The API-key trust seed never matched a real key.** `seedApiKeyTrustFile()` wrote the
key verbatim into `customApiKeyResponses.approved`, but Claude Code stores and compares
only the last 20 characters (`key.trim().slice(-20)`, applied on both the write and the
lookup). For any real key the seed missed, so claude stopped at the interactive
"Detected a custom API key in your environment" prompt, whose default is
"No (recommended)": the launch hangs, or silently refuses the key this feature just
injected and falls through to an OAuth login the isolated config dir does not have. It
survived review because a keyless llama.cpp/llama-swap endpoint uses DEFAULT_API_KEY
('local-dummy-key', 15 chars), where slice(-20) returns the whole string and the seed
matches by accident, and every test used a key shorter than that. Now truncated through
`truncateApiKeyForTrustFile()`, with a test using a 57-character key that also asserts
the full credential never reaches that second file.

**One `confirmed` flag answered two different questions.** The context-floor warning
("this model's window is below what this CLI needs") and the swap-conflict warning
("loading this unloads the model another session is using") shared it, and the context
check runs first, so a user clicking "launch anyway" past the context warning silently
consented to evicting someone else's model. They are about different people, so an
answer to one is not consent to the other. Both routes now read `confirmedContext` and
`confirmedSwap` independently; the legacy `confirmed` still means both, because it
shipped in this feature's HTTP-API-only cut and an existing caller must keep working.
The frontend answers each question with its own flag and accumulates them, on the
one-shot path, the restart path and the batch carry-forward alike.

Also from the same review: the swap-confirm dialog no longer renders " are currently
using ..." when multi-user scoping leaves the affected-session list empty (the swap is
blocked regardless of ownership; only the NAMES are scoped), and the per-endpoint
llama-swap log tails are closed in `WebServer.stop()` instead of only by the idle sweep
whose interval that same teardown disposes.

DevvynandClaude Sonnet 5 5fc391a47c fix(custom-model): address fourth pre-merge review + merge upstream master (Ark0N)
Merged upstream/master (22 commits: reboot-restore recovery feature,
terminal keycode229 recovery work, install.sh/CLI-catalog generator
changes, CHANGELOG/version bump to 1.30.0) into this branch. No
conflicts; git auto-merged every overlapping file (CLAUDE.md,
docs/api-reference.md, app.js, index.html, styles.css, routes/index.ts,
session-routes.ts, schemas.ts, server.ts).

Two required fixes from the latest review:

1. privilegedEnvKeys widening (stock.ts) changes behaviour outside this
   feature. The reviewer decided to keep both CLAUDE_CODE_MAX_CONTEXT_TOKENS
   and CLAUDE_CONFIG_DIR listed (types.ts's rule that every traffic-
   redirecting var this feature introduces must appear there stays
   literally true), and asked for the real consequences documented
   instead of hidden:
   - Corrected session-env-clamp.ts's fileoverview, which stated the
     opposite of what the code now does (reboot-restore's clamp call
     used to be able to strip nothing for claude; it now strips a
     persisted CLAUDE_CONFIG_DIR for a non-granted owner).
   - Corrected the rationale comments in stock.ts: privilegedEnvKeys
     has exactly one consumer (ownerClampedEnvKeys, feeding the
     generic envOverrides clamp on create/quick-start/reboot-restore),
     not the custom-model routes.
   - Added a CLAUDE.md line to the CLAUDE_CONFIG_DIR gotcha covering
     the admin-only-in-multi-user-mode and reboot-restore-strips-it
     consequences.
   - Added a "Claude multi-user clamp" test next to the existing
     DeepSeek/OMP ones, pinning the new stripping behaviour.

2. GET .../running-status (custom-model-routes.ts) no longer passes
   the raw llama-swap `cmd` field (the literal launch line, which can
   carry model paths and --api-key) to the browser -- the frontend
   only ever reads model/state, cmd exists solely for server-side
   parseCtxFromCmd() during discovery. Added a test asserting the
   response never contains cmd or a planted secret.

Also regenerated config/clis.stock.json and install.sh's catalogue
block (npm run generate:cli-catalog) to clear drift introduced by the
upstream merge, since it was failing the sync check.

Left to the reviewer, as they said they'd take at merge: the two
"comments pointing at removed code" cleanups, the two stale CLAUDE.md
counts, and the small items list (mode==='claude' frontend branch,
isCliAvailable() unknown-id gap, shared confirmed flag ordering,
one-shot cancel toast severity, pumpLlamaSwapLogTail buffer cap).

DevvynandClaude Sonnet 5 afb6754453 fix(custom-model): address third pre-merge review (Ark0N)
Blocker 1: the loading banner hides itself ~200ms after it reopens.

- _showCenterStatus reuses one shared DOM node; dismiss() scheduled
  el.hidden = true 200ms later with nothing to cancel it. On the
  Claude path, switchingToast.dismiss() is followed by one same-
  origin request (5-30ms locally) before _watchLlamaSwapLoading opens
  the new banner -- well inside that window -- so the stale timer
  fired against the shared node and hid the fresh banner, leaving the
  whole model-load wait with no progress text, no log line and no
  reachable Cancel button.
- Fixed by parking the pending timeout on the element and clearing it
  at the top of _showCenterStatus. Added a regression test that
  reproduces the exact repro (open, dismiss, reopen 20ms later,
  advance past 200ms) alongside the existing Cancel-button DOM tests;
  confirmed it fails without the fix and passes with it.

Blocker 2: the swap-conflict warning named other users' sessions.

- Both affectedSessions scans (POST .../custom-model and quick-start)
  walked the whole session map with no ownership filter, so in multi-
  user mode a non-admin pointing their own session at a shared
  endpoint learned another user's session name and id -- which with
  autoNameSessions on is that user's own prompt.
- The swap is still blocked pending confirmation regardless of
  ownership (a foreign session is just as real a disruption); only
  which ones get NAMED back to the caller is scoped, via the
  already-imported canAccessOwned. Added a two-owner test to
  test/routes/session-custom-model.test.ts covering both the
  foreign-owner (blocked, not named) and same-owner (named) cases.

Smaller ride-along fixes:

- server.ts boot recovery now passes contextLength into
  applyCustomModelInjection, so CLAUDE_CODE_MAX_CONTEXT_TOKENS is
  correctly rebuilt into _envOverrides after a restart instead of
  surviving only because tmux retains the old setenv.
- pumpLlamaSwapLogTail's finally now deletes by IDENTITY, not just by
  key, so an aborted pump finishing after a newer entry was created
  for the same endpoint can no longer delete that newer entry and
  orphan its connection.
- docs/custom-model-endpoints.md now notes that clearing a custom
  model removes injected keys by name, including CLAUDE_CONFIG_DIR --
  so a session that also had CLAUDE_CONFIG_DIR set via envOverrides
  (the per-client-account case) silently falls back to the default
  account on clear.

Left for later, as flagged in the review itself: the quick-start
case-scaffolding/cancel ordering (real behavioural reordering across
a large handler, too risky to make without a live re-test), and
retiring runCustomModelEntry's mode === 'claude' branch behind a
launchStrategy registry field (explicitly deferred by the reviewer to
"the next one").

DevvynandClaude Sonnet 5 b45a96358e feat(custom-model): warn before launching Claude on a model too small for its own overhead
Claude Code's own fixed per-turn overhead (system prompt + tool schemas,
~36.4K tokens measured live) can exceed a small local model's entire real
context before any conversation history exists to compact — confirmed
live twice as an in:0 out:0 failure on the very first message sent.
CLAUDE_CODE_MAX_CONTEXT_TOKENS cannot fix this: it only governs when
history gets compacted, and there is none on message one.

- exceedsSafeContextFloor() (custom-model-routes.ts): true when a CLI's
  registry entry declares contextLengthVar (currently only claude) and
  the model's discovered context is below CLAUDE_MIN_SAFE_CONTEXT_TOKENS
  (40000). A no-op for every other CLI by construction.
- Both apply routes (POST /api/sessions/:id/custom-model and the
  quick-start customModel path) check this before the swap-conflict
  check and before launching/restarting anything, returning
  {requiresContextWarning, modelId, contextLength, minSafeContextTokens}
  — skipped when confirmed:true.
- Frontend: #customModelContextWarningModal + _confirmContextWarning/
  _resolveContextWarningConfirm (session-ui.js), wired into both
  _quickStartWithCustomModelConfirm and _runCustomModelEntryViaRestart
  (the path Claude actually uses) ahead of the swap-confirmation check.
  Explains the fix in-modal: give the model an explicit larger -c/
  --ctx-size in llama-swap instead of relying on --fit-ctx, which
  optimizes for the biggest model that fits rather than the biggest
  context.

Tests added for the route-level warning/confirm/skip cases and the
frontend modal + launch-flow wiring. Docs updated (custom-model-
endpoints.md, wiki/Custom-Model-Endpoints.md) and the PR's running
changeset extended.

DevvynandClaude Sonnet 5 0929694012 fix(custom-model): actually trigger the llama-swap load, not just watch for it
Root cause of "it doesn't look like llama-swap is actually switching the
model" (confirmed live: no load_model line in llama-swap's own logs after
applying a selection). llama-swap has no "switch model" admin endpoint - the
ONLY thing that starts a swap is a real inference request naming the model.
Every previous fix (the conflict check, the loading banner) assumed a swap
would start on its own; nothing ever actually asked llama-swap to load
anything until the launched CLI's first real prompt did, which could be
much later than "applying the selection" implied.

Adds triggerLlamaSwapLoad() (custom-model-routes.ts): sends the smallest
real request that will start a load - POST <baseUrl>/v1/chat/completions,
max_tokens: 1, one throwaway message - fire-and-forget (never awaited by
the caller; the frontend's own running-status polling is what actually
confirms readiness). Wired into both apply paths (the dedicated restart
route and the one-shot quick-start route), fired whenever the target model
isn't already the one loaded and ready - a broader condition than the
existing swapNeeded (which only gates the "this will evict another
session's model" confirmation ask and deliberately stays narrow to that).
modelSwapInProgress in both routes' responses now reflects this same
broader condition too, so the frontend's loading banner actually correlates
with a real in-flight load rather than only firing when something else
happened to be loaded already.

DevvynandClaude Sonnet 5 bcebc81fcd feat(custom-model): detect llama-swap model conflicts before switching
Root-caused the user's earlier confusion ('the terminal says opus even though
something is waiting for llama to load'): llama.cpp runs exactly one model at
a time, and llama-swap unloads/reloads it on demand - a swap can take
anywhere from a few seconds to well over a minute, during which a session
looks indistinguishable from one still on the native backend.

1. Feature-detects llama-swap (vs. plain llama.cpp/any OpenAI-compatible
   server) via its own GET /running, which plain llama.cpp has no concept of
   at all. New GET /api/model-endpoints/:id/running-status route exposes this
   read-only, for the frontend's polling loop below.

2. Before applying a selection, POST /api/sessions/:id/custom-model now checks
   what llama-swap currently has loaded. If it differs from the requested
   model AND another live session's own customModel selection is actively
   using that loaded model, the apply is refused with a
   {requiresConfirmation, currentlyLoadedModel, affectedSessions} payload
   instead of silently switching. A "confirmed: true" field on the retry
   skips the check. Switching with nothing else affected proceeds
   immediately, no confirmation asked, only ever when there is something to
   warn about.

3. The frontend (runCustomModelEntry) shows a native confirm() naming the
   affected session(s) and the model they'd lose, matching this codebase's
   existing convention for this class of decision (delete case, kill
   session, etc.) rather than a new modal. On a successful apply the response
   also carries modelSwapInProgress; when true, a new _watchLlamaSwapLoading
   poll shows a sticky "Loading <model>..." toast via the new running-status
   route until llama-swap reports the target model ready (bounded at 2
   minutes), so a prompt sent mid-swap reads as "loading", never as silence
   or an answer from whatever was loaded a moment before.

Checks are read-only against llama-swap's own /running - never /props, which
takes a ?model= and can itself trigger a load as a side effect of asking.

DevvynandClaude Sonnet 5 25f22b9839 test(custom-model): update session-custom-model route test for CLAUDE_CONFIG_DIR isolation
Fixes the CI failure on the last two commits: this route test asserted an
exact envKeys list for a claude-mode apply that predates the
CLAUDE_CONFIG_DIR isolation fix, so it failed on the new CLAUDE_CONFIG_DIR
entry it correctly started appending. Updates the expected list and adds
assertions for the isolated config dir path and the pre-seeded
.claude.json trust-approval file, matching the behavior added in the two
prior commits rather than just tolerating it.

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.

DevvynandClaude Sonnet 5 41416566aa feat(custom-model): Custom Model Endpoint Profiles (local or cloud, all harnesses)
Point any Codeman-supported harness (Claude, opencode, Codex, Gemini, Pi,
Grok, DeepSeek, OMP) at a custom OpenAI-compatible endpoint instead of its
native cloud backend, for a given session. Covers local hardware (llama.cpp,
Ollama, vLLM, DGX Spark, Strix Halo) and cloud (Azure AI Foundry, OpenRouter).
Off by default (customModelEndpointsEnabled, synced, default OFF).

- Registry: capabilities.customModelInjection per CLI entry (env /
  configContentEnv / configDir / unsupported kinds)
- Pure injection builder (custom-model-injection.ts) turning an endpoint +
  model id into the real env vars / config content per CLI
- Endpoint store + CRUD routes (custom-model-hosts.ts,
  custom-model-routes.ts), discovery via GET /v1/models, SSRF-guarded
- Session integration: Session.setCustomModel()/restartCli()
  (POST /api/sessions/:id/custom-model), reusing the existing
  respawn-pane -k primitive to restart the CLI process with new env
- Multi-user hardening: every new redirect-capable env var added to its
  CLI's privilegedEnvKeys, closing a pre-existing gap where several were
  already reachable via the generic envOverrides field's prefix allowlist
- Standalone scripts/test-local-llm-harnesses.mjs: spawns real CLI binaries
  against a real endpoint outside the web UI, independent of tmux/sessions
- Mock-server contract tests (test/fixtures/mock-openai-server.ts) replaying
  every CLI's injected values through a real HTTP shape

Real end-to-end validation against a live llama-swap server (inside a
codeman/agent:llm-test Docker image with all 9 CLI binaries) found and
fixed three real bugs before they shipped:
- Codex's config.toml schema was wrong ([model].default table instead of
  a top-level model string + [model_providers.custom]); fixing it then
  surfaced a genuine, documented protocol incompatibility (Codex only
  speaks the Responses API since Feb 2026, which llama.cpp/llama-swap
  don't implement)
- Claude Code's async session-title-generation call validates
  ANTHROPIC_DEFAULT_HAIKU_MODEL against its own internal model list and
  hangs the whole -p invocation on an unrecognized name; documented for
  chunk 6, worked around in the standalone script only (--bare is NOT
  safe for a real interactive session, which needs hooks)
- The discovery route's authStyle: 'both' option (send both Authorization
  and api-key headers) reliably hung a real server; removed the option
  entirely rather than just changing the default

Status: draft. Chunk 6 (frontend toolbar/settings UI) not yet built — see
PR.md and deployment_plan.md for the full chunk breakdown and confidence
table.
