 ### 🔧 Bug Fixes
 
+- **fix(executor):** Llama / OpenAI-compat base URL normalization — a `baseURL` without a path (e.g. `llama.example.foo`) or with a non-`/v1` path (e.g. `bar.example.com/foo`) now correctly gets `/v1/chat/completions` appended, fixing the 404 on message sends while `GET /model` still worked. ([#3519](https://github.com/diegosouzapw/OmniRoute/pull/3519) — thanks @hartmark)
+- **fix(sse):** empty-choices chunks without usage are dropped instead of injecting retry text — a streamed chunk carrying an empty `choices` array and no `usage` is now silently skipped rather than emitting placeholder retry text into the stream, eliminating spurious content for clients that send such keepalive-style frames. ([#3513](https://github.com/diegosouzapw/OmniRoute/pull/3513) — thanks @diegosouzapw)
+- **fix(opencode-plugin):** repaired the corrupted `index.ts` that broke the npm `publish-opencode-plugin` build (introduced by the #3435 branch) — removed two duplicated code blocks (apiFormat + debug-logging), dropped the local `normaliseFreeLabel` superseded by the `naming.ts` extraction, fixed an undefined `sdkBaseURL` reference, declared the missing `startupDebug` / `logLevel` feature-schema fields, and fixed `shortProviderLabel` dropping the prefix on a long displayName with no alias. Plugin now builds (DTS clean) with all 254 tests green. ([#3435](https://github.com/diegosouzapw/OmniRoute/pull/3435) — thanks @diegosouzapw)
 - **fix(catalog):** Codex CLI model-catalog refresh no longer errors — `GET /v1/models` now returns a top-level `models: []` array for Codex clients (detected via the `originator` / `user-agent` = `codex_*` headers it sends on `GET /v1/models?client_version=...`), so `codex_models_manager` stops failing to decode the OpenAI-standard response and no longer logs `failed to refresh available models` on every startup. 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 break Codex's agent behaviour — an empty list keeps Codex on its built-in model info (same inference as before, minus the error). Non-Codex OpenAI clients receive the unchanged `{object,data}` response. ([#3481](https://github.com/diegosouzapw/OmniRoute/pull/3481) — thanks @diegosouzapw)
 - **fix(provider):** Cursor's Responses-API-shaped bodies on `/chat/completions` are detected and handled — a body with `input` but no `messages` is now classified as `openai-responses` (instead of forcing `openai` and building from undefined `messages` → upstream 400); standard OpenAI clients are unaffected by the `messages===undefined` guard. ([#3490](https://github.com/diegosouzapw/OmniRoute/pull/3490) — thanks @borodulin)
 - **fix(sse):** numeric provider IDs normalized to strings across 4 more surfaces — extends #3427 to the Responses-API SSE passthrough (`response_id`/`item_id`/`call_id`), the buffered/flush path in `stream.ts`, the dedup-key builders, and `sseParser.ts`, preventing `undefined` lookups when IDs arrive as numbers. ([#3451](https://github.com/diegosouzapw/OmniRoute/pull/3451) — thanks @disafronov)

 ### 📝 Maintenance
 
 - **feat(docs):** doc-accuracy gate — new `npm run check:fabricated-docs` (`scripts/check/check-fabricated-docs.mjs`) indexes the codebase (api routes, env vars, CLI commands) and flags API-path/env-var/CLI/hook/file-ref claims in `docs/**` + `AGENTS.md` that don't exist in source (soft-fail by default, `--strict` for CI; wired into `check:docs-all`). Also refreshes the AGENTS.md live counts against source. ([#3510](https://github.com/diegosouzapw/OmniRoute/pull/3510) — thanks @oyi77)
+- **chore:** ignore local quality reports and prompt artifacts (`quality-metrics.json`, `PLANO-/RELATORIO-QUALITY-GATES.md`, stray prompt `.txt` files) so they no longer surface in `git status`. (thanks @diegosouzapw)
