v2.0.141

v2.0.141 - tool routing diagnostics

This release does not widen native bridge production defaults.

Tool routing diagnostics

• Added ToolRoute[...] request logs for tool-bearing chat requests. The log
  records requested tools, tool_choice-filtered tools, native mapped/unmapped
  partitions, native bridge decision reason, tool preamble tier, and compact
  routing reasons.
• /v1/responses now drops a forced tool_choice when that choice points at
  an unbridged server-side tool such as file_search, computer_use_preview,
  or mcp. This prevents a translated request from carrying a forced tool that
  no longer exists after flattening.
• README now has a short FAQ explaining how to interpret "no tool calls" and
  why native bridge is not a general local IDE tool fix.

WebFetch trace canaries

• scripts/native-bridge-smoke.mjs now summarizes redacted
  webFetchTrace.state values from proto trace JSONL files. Gated WebFetch
  canaries can now report whether the LS reached pending_permission,
  completed_web_document, error, or another known branch without manually
  inspecting trace records.
• The trace summary is diagnostic only and does not change smoke pass/fail
  criteria.

Validation

• Added regression coverage for Responses server-side tool_choice pruning,
  tool routing diagnostics, and smoke WebFetch trace summaries.
