PR #3422 ('allow OpenAI usage-only empty choices chunks') reintroduced the
assistant-content injection '[OmniRoute] Upstream returned an empty response.
Please retry.' for empty `choices: []` chunks that carry no valid usage. Clients
(Goose/opencode) feed that text back as a turn and spin in a retry loop -- the
exact regression #3400 had fixed by dropping the chunk.
Restore the drop behavior for the no-usage case while preserving #3422's
standards-compliant forwarding of usage-only `include_usage` final chunks.
Realign the mislabeled stream-utils test (it asserted the injection) and add a
dedicated regression guard.

Add generated quality gate reports, metrics files, and local setup prompt
artifacts to .gitignore to prevent committing environment-specific or
temporary files.
Codex's model-catalog refresh (codex_models_manager) does
GET /v1/models?client_version=<v> and decodes a JSON object with a
TOP-LEVEL `models` array. OmniRoute answers in the OpenAI-standard
`{object,data}` shape, so codex fails with "missing field `models`"
and logs "failed to refresh available models" on every startup.
Detect codex clients via the `originator` / `user-agent` = `codex_*`
headers they send and add an EMPTY top-level `models: []` so the decode
succeeds. Non-codex OpenAI clients keep the byte-identical `{object,data}`
response.
The array is intentionally empty: codex replaces its built-in per-model
agent prompt (`base_instructions`, ~21k chars) with whatever a populated
entry carries for the selected model, so emitting our catalog would drop
the agent prompt to nothing and break codex's agent behaviour (verified
empirically against codex 0.137). An empty list keeps codex on its
built-in model info — same inference as before, minus the error.
Validated end-to-end with the real handler against codex 0.137:
"failed to refresh available models" → 0 occurrences, instructions
preserved (built-in Codex agent prompt, not empty).

PR #3435's branch shipped a corrupted index.ts that never built — the npm
publish-opencode-plugin job failed on DTS errors. Root causes:
- Duplicate apiFormat block (ensureV1Suffix/DEFAULT_ANTHROPIC_PREFIXES/
resolveApiBlock) — kept the canonical #3420 copy (anthropic url WITHOUT /v1),
removed the duplicate that wrongly appended /v1 to the Anthropic SDK base.
- Duplicate debug-logging block (DebugLogEntry + debugLog* + createDebugLoggingFetch)
with mid-file imports — kept the canonical copy using top-of-file imports.
- Local normaliseFreeLabel def superseded by the naming.ts extraction —
removed it, routed the lone caller to the imported _normaliseFreeLabel.
- sdkBaseURL → resolvedBaseURL (undefined identifier in the auth loader).
- featuresSchema missing startupDebug + logLevel (referenced but never declared).
- shortProviderLabel dropped the prefix on long displayName + no alias; now
keeps the long label, matching the test intent.
Plugin builds (DTS clean) and all 254 tests pass.
fumadocs-mdx requires a YAML title in every .md file and does not support
nested object entries in meta.json pages arrays — both were introduced by
PR #3438 and broke the webpack build.
#3462 added a process.env.COMMAND_CODE_VERSION read but did not document it,
tripping the env-doc-sync gate on the release branch (PR-merges bypass the
pre-commit check-docs-sync hook). Add the var to .env.example + ENVIRONMENT.md.

The custom-models loop in getUnifiedModelsResponse gated every model through hasEligibleConnectionForModel(getConnectionsForProvider(...)). no-auth providers (theoldllm, etc.) never create DB connection rows, so that returned [] and the gate dropped every imported/custom model for them — the Playground dropdown showed nothing for imported models while built-in/custom models on auth providers worked. Built-in models survived because they go through providerSupportsModel(), which already has a no-auth bypass (#2798).
The custom-model gate now applies the same no-auth bypass, keeping the eligibility check (with parentProviderType) intact for auth providers.

Claude Code -> claude-opus-4-8 turns intermittently died with 'tool call could not be parsed (retry also failed)'. OmniRoute's claude identity cloak rebuilt the anthropic-beta header from scratch and unconditionally forced interleaved-thinking-2025-05-14 (+ advanced-tool-use / effort for heavy agents), even when the client never negotiated them. The forced interleaved-thinking conflicts with tool_choice-forced turns, producing malformed opus tool_use streams (and sibling 400 'Thinking may not be enabled when tool_choice forces tool use').
selectBetaFlags now takes the client's inbound anthropic-beta: when present, thinking/effort betas are only emitted if the client requested them. Opaque clients (no header — the OAuth cloak path) keep the full set unchanged, so existing behavior and the #2454 model-tier gating are preserved.

Vertex AI's FunctionCall/FunctionResponse protos have no id field; emitting it made Vertex reject tool calls with 400 'Unknown name id'. The id is now stripped only when the routed provider is vertex/vertex-partner (threaded via credentials._provider), preserving it for the public Gemini API where Gemini 3+ uses it for signature matching.
