Walkthrough

OpenCode Go and OpenCode Zen providers were added with model discovery and protocol-specific completion routing. Completion handling now tracks request ownership, cancels active responses, and isolates stream buffers across requests. Presenter cleanup always stops the completion handler with callbacks skipped.

Changes

OpenCode provider support

Layer / File(s) Summary
Model discovery and protocol adapters
basilisk/provider_engine/opencode_go_engine.py
The OpenCode engine loads and validates model catalogs, applies provider-specific metadata and sampling policies, routes completion processing to protocol adapters, and handles response cancellation.
Provider registration and validation
basilisk/provider.py, README.md, tests/provider_engine/test_opencode_go_engine.py, tests/conftest.py, pyproject.toml, .gitignore
Registers OpenCode Go and OpenCode Zen, documents both providers, and adds tests for discovery, routing, metadata, sampling, client URLs, and cancellation. Test configuration adds an empty YAML source and warning filter. The ignore file adds .firecrawl/.

Completion lifecycle and cancellation

Layer / File(s) Summary
Request ownership and cancellation
basilisk/completion_handler.py, basilisk/provider_engine/base_engine.py
Tracks request state and per-request buffers. Stop handling cancels active responses, and request-aware callbacks prevent stale work from changing current completion state.
Lifecycle callbacks and regression coverage
basilisk/completion_handler.py, basilisk/presenters/conversation_presenter.py, tests/test_completion_handler.py, tests/presenters/test_conversation_presenter.py
Tests cover startup and stop races, stale callbacks, cancellation, and buffer isolation. Presenter cleanup always calls stop with callbacks skipped.

Merge Risk: 🔵 Low · up to b22a9

This change adds the OpenCode Go and OpenCode Zen providers and makes completion stop and cancel behavior track each request. Earlier concerns are fixed: an older completion can no longer clear a newer completion's state, and the documentation and test conventions have been updated. One minor question remains open: whether the new provider display names should be translatable. The names follow the same pattern as existing providers, so the change is mergeable with low risk.

Updated this PR with all six review fixes and a complete OpenCode Go compatibility audit.

Highlights:

  • Fixed Gemini custom-base routing with ResourceScope.COLLECTION.
  • Added translator context, the OpenCode Go label/README update, response-hook typing/docs, and requested test cleanups.
  • Audited all 29 model IDs currently returned by the OpenCode Go endpoint.
  • OpenCode Go kimi-k2.5, kimi-k2.6, kimi-k2.7-code, and kimi-k3 now always send temperature=1.0 and top_p=0.95; their unsupported UI controls remain hidden.
  • gpt-5.6-luna omits unsupported temperature and top_p on the Responses transport.
  • Added complete route and vision classification coverage, while preserving the conservative fallback for future models and keeping OpenCode Zen isolated.
  • Preserved Zen Kimi K3's existing sampling omission policy.

Validation:

  • Focused OpenCode provider tests: 90 passed
  • Full suite: 971 passed, 14 skipped
  • Ruff: clean
  • git diff --check: clean
  • Windows portable build rebuilt, deployed, hash-verified, and smoke-tested

All six CodeRabbit review threads have been resolved after the fixes were pushed.

Follow-up review fixes are now pushed in a258519 and 7452a66.

  • Bound completion response state and queued UI callbacks to request identity, preventing an older worker from clearing or finishing a newer request.
  • Made stream buffering request-owned so cancelled/erroring partial text cannot leak into a restarted completion.
  • Made stopped-completion notification request-owned so an old queued stop callback cannot affect a replacement request.
  • Added deterministic stale-cleanup, stale success/error, stop/restart, error/restart, and queued-stop/replacement tests.
  • Completed the OpenCode cancellation docstring and remaining pytest-mock cleanup.

Final validation:

  • Focused completion/OpenCode tests: 97 passed
  • Full suite: 977 passed, 14 skipped
  • Ruff and git diff --check: clean
  • Portable installation rebuilt from 7452a66, 1,434 files hash-verified, installed markers verified, hidden smoke passed, zero Basilisk processes remain

The two new CodeRabbit threads are resolved after these fixes.

Final completion-lifecycle follow-up is pushed through ffaf0a0.

Additional fixes:

  • Worker creation/assignment/start is atomic before on_completion_start.
  • Provider work, error callbacks, and start-callback failure cleanup honor a request-owned start gate.
  • Stop and provider startup are lock-linearized so cancellation cannot be followed by late progress sound/provider startup.
  • Logical dead-request stops always silence progress audio.
  • Conversation teardown unconditionally performs skip-callback cleanup.
  • Failed Thread.start() rolls back all published lifecycle state.
  • Added deterministic immediate-stop, published blocking-response cancellation, fast failure, callback exception, stop/start barrier, dead-worker sound, presenter cleanup, and retry coverage.

Final validation:

  • Full suite: 987 passed, 14 skipped
  • Focused completion/presenter: 49 passed
  • Focused OpenCode: 90 passed
  • Ruff and git diff --check: clean
  • Portable rebuilt from ffaf0a0; 1,434/1,434 installed hashes match; 25 installed policy markers pass; hidden smoke passed; zero Basilisk processes remain

The final CodeRabbit atomic-start thread is resolved after the fixes were pushed.

Addressed the remaining review threads in b22a982:

  • The start-callback failure path now bounds its worker join (1 s), so a wedged provider cannot hang the UI thread.
  • Removed the write-only _startup_request.
  • The CodeQL unused-local alerts came from None defaults that were never read. The engine and response are now read together through _cancellable_response(), so every default is used.
  • Commented the deliberate ValueError swallow when closing a Gemini stream, and it now logs at debug level.

The suite passes (987 passed, 14 skipped), and ruff check and ruff format --check are clean.
