- Around line 303-311: Update the native-lane enforcement description to reflect
the current contract: `passthrough-dispatch.ts` computes
`undeclaredToolGuardActive` once, and `passthrough-delivery.ts` uses that flag
rather than reading `inboundWire`. Clarify that Responses refuses with any
readable catalog, while deferred wires refuse only when the catalog is
explicitly empty.

When a Chat or Messages request with explicit tools: [] uses the native Chat/Anthropic fast path or a translated adapter delivery instead of the openai-responses passthrough, this new fact is never enforced: the native handlers return before these options are set, while run-turn-execution.ts:645 and adapter-delivery.ts:186,270 still disable declared-name enforcement solely from inboundWire. In those common provider configurations an upstream Write call is therefore relayed as a successful tool call rather than the newly documented undeclared_tool_call refusal; carry the explicit-empty flag into the native, run-turn, and adapter delivery guards as well.
Useful? React with 👍 / 👎.

Security review at 75e0e79. Native Responses enforcement is unchanged (inboundWire defaults to responses); Chat/Messages previously never refused on this lane and now gain a deny-all for explicit tools: [] while keeping default.* normalization; undeclared_tool_call keeps its code across buffered/SSE/Messages so Anthropic clients no longer see a retryable overload; refusal still precedes continuation storage. Focused guard/passthrough/test-layout suites pass 152/0 on a merge with current dev; typecheck clean; CI green. Pushed a doc correction for the CodeRabbit finding (native-lane activation wording) within the 600-line budget.

Reject guarded calls before saving continuation state.undeclared_tool_callin streaming and JSON envelopes. Messages returns the deterministic refusal asapi_error, rather than a retryable overload.Verification
