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 211b872335 feat(custom-model): skip Claude Code's first-run wizard on custom-model launches
A fresh, isolated CLAUDE_CONFIG_DIR (used to keep an injected API key
away from a stored claude.ai OAuth login) looks like a brand-new Claude
Code profile to the CLI, so it replays its ENTIRE first-run sequence on
every single launch: the theme picker, the security-notes screen, the
per-project "trust this folder?" dialog, and (running with
--dangerously-skip-permissions) a one-time bypass-permissions warning —
confirmed live, none of which a real, already-onboarded profile shows
again.

- New registry-declared env-kind field `skipFirstRunPrompts` (alongside
  apiKeyTrustFile, which it reuses) — claude's entry only, carried
  through buildCustomModelInjection (pure) into
  applyCustomModelInjection (IO).
- seedFirstRunOnboardingState(): merges hasCompletedOnboarding: true and
  this session's own projects[workingDir].hasTrustDialogAccepted: true
  into the same <configDir>/.claude.json the API-key trust file already
  writes to — other projects and other fields on this session's own
  entry are left untouched.
- seedSkipBypassPermissionsPrompt(): merges
  skipDangerousModePermissionPrompt: true into <configDir>/settings.json,
  a separate file, same corrupt-tolerant merge behavior.
- applyCustomModelInjection() gains an optional workingDir parameter,
  threaded from session.workingDir (dedicated apply route) /
  resolvedCasePath (quick-start route) — boot recovery omits it
  (a dialog already answered once needs no re-seed on the same,
  persisted isolated directory).

Tests added at the pure-builder, IO-wrapper (including merge-preserves-
other-fields and corrupt-file-tolerance cases), and existing directory-
listing assertions updated for the new settings.json file. Typecheck/
lint/format clean; full suite shows no new regressions (baseline
pre-existing Windows-environment failures unchanged, 8 more passing
tests than before — the ones added here).

DevvynandClaude Sonnet 5 97464bfa27 fix(custom-model): pre-approve the injected API key in the isolated Claude config dir
The CLAUDE_CONFIG_DIR isolation from the previous commit fixed the cosmetic
auth warning but introduced a real regression: an otherwise-empty config
directory has none of a real profile's prior custom-API-key approvals, so
Claude Code stops at an interactive 'Detected a custom API key - use it?'
prompt on every single launch. Confirmed live. With nobody at a TTY to
answer, the prompt's own default ('No') silently refuses the very key this
feature just injected, which looks like the endpoint being ignored.

Adds apiKeyTrustFile to the env-kind customModelInjection capability shape
({relPath, shape: 'claude-api-key-responses'}), set on claude's entry to
{relPath: '.claude.json', shape: 'claude-api-key-responses'}. The apply step
merges customApiKeyResponses.approved: [apiKey] into
<isolatedConfigDir>/.claude.json - the exact field a real answered prompt
itself writes to (confirmed against a real ~/.claude.json after answering by
hand once), so this answers the prompt in advance rather than bypassing it.
Merges onto whatever the CLI already wrote into that file on an earlier
launch in the same isolated directory rather than overwriting it; a missing
or corrupt file is treated as empty rather than failing the apply.

DevvynandClaude Sonnet 5 0e8b1981af fix(custom-model): isolate Claude config dir and inject real context length
Addresses two live-validation findings on the Run-menu custom-model picker:

1. Both claude.ai and ANTHROPIC_API_KEY set warning. Claude Code still
   coexists an OAuth login with an injected ANTHROPIC_API_KEY in the same
   config directory and warns about it (confirmed cosmetic - the API key
   wins for actual requests, verified via a real session's own API Usage
   Billing line). A custom-model claude session now gets an isolated
   CLAUDE_CONFIG_DIR (registry-declared via a new configDirVar field, empty,
   no files written into it) so there is nothing to conflict with. projects
   is symlinked (junction on Windows) back into the real config dir so the
   response viewer, subagent windows and Read My Mind keep working for that
   session, best-effort.

2. Context-window overflow. Claude Code assumes a large default context
   window for a model id it doesn't recognise and never compacts, so a
   custom endpoint's real, much smaller context (verified live: a 400
   exceeding a 16384-token llama-swap model with a stock ~33.7K-token system
   prompt) silently overflows. Discovery now also learns each model's real
   context length from llama.cpp/llama-swap's GET /props?model=<id> (n_ctx),
   but ONLY for a model llama-swap's own /v1/models response already marks
   status.value === 'loaded' - never an unloaded one, since llama-swap
   treats ?model= as a routing hint and probing an unloaded model risks
   triggering an actual, slow, GPU-swapping load as a side effect of
   read-only discovery. A server with no status field at all gets no
   enrichment rather than a guess; a model not probed this round keeps its
   previously-learned value until it disappears from the list entirely.
   Stored per model (CustomModelHost.modelContextLengths) and applied via a
   new contextLengthVar registry field, set to
   CLAUDE_CODE_MAX_CONTEXT_TOKENS for claude.

Both new fields live on the existing env-kind customModelInjection
capability shape, declared only on claude's registry entry - every other
CLI's injection is unaffected (pinned by test).

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 61779745aa test(custom-model): make the harness smoke test dynamic, verify all 9 CLIs end-to-end
Rewrites scripts/test-local-llm-harnesses.mjs -> .ts to read the live CLI
registry (enabledClis()) and call the real production
buildCustomModelInjection()/applyConfigDirInjection() instead of keeping a
second hand-maintained copy of every CLI's env/config shape. A future
registry change (new CLI, edited env var, fixed config template) is now
picked up automatically with zero edits to this script; only the one-shot
invocation flags (info the registry genuinely doesn't model) stay in a
small hand-maintained ONE_SHOT table, and a registry CLI with no entry
there reports UNKNOWN rather than being silently skipped.

Extracted src/custom-model-injection-apply.ts (applyConfigDirInjection/
removeConfigDir) so the production route and this script share one
implementation instead of two.

Full end-to-end run against a real llama-swap server, inside a
codeman/agent:llm-test Docker image with all 9 CLI binaries:

- claude, opencode, pi, grok, omp: PASS, real "hello world" replies
- codex: confirmed FAIL for a real protocol reason, not a bug — it only
  speaks the Responses API since Feb 2026, which llama.cpp/llama-swap
  don't implement
- gemini: confirmed FAIL, unresolved after real investigation — an
  undocumented GATEWAY AuthType gemini-cli selects once
  GOOGLE_GEMINI_BASE_URL is set rejects every auth-key format/override
  tried
- deepseek: reaches the server (env vars are read) but gets a consistent
  HTTP_404; root cause not identified, documented as best-effort/unknown
- antigravity: SKIP, no known mechanism (unchanged)

Two real bugs found and fixed along the way (grok, pi/omp registry
entries in stock.ts): grok's original recipe (env vars) was flat-out
wrong, not just unverified — the real mechanism is a config.toml
[model.<name>] block redirected via GROK_HOME. pi/omp's PI_CONFIG_DIR
does nothing for either (grepped pi's entire bundled source — the string
appears nowhere); the real redirect is the child process's own HOME, and
both need `models` as an array of {id} objects, not an object keyed by
id (silently loaded zero models otherwise).

deployment_plan.md, PR.md, docs/custom-model-endpoints.md, and CLAUDE.md
updated with the final confidence table reflecting all of the above.

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.
