Description
CA rotation propagates to gRPC OTLP only via forced reconnect (internal/telemetry/exporters.go:729-744); with tls CA file watching enabled and no grpc_reconnection_period set, a rotated CA silently never applies. Add a Warnings() advisory for that combination.
Acceptance Criteria
- #1 The combination produces a startup warning naming the fix
- #2 Covered by a config warnings test
Definition of Done
- #1 just check passes (the full gate; it is what CI enforces)
- #2 just gen leaves no diff (only if a generated artifact’s inputs changed)
- #3 just –fmt –check passes and every new recipe has a # doc comment and a [group(…)]
Implementation Plan
Lane H adds the gRPC CA-rotation-without-reconnection advisory without changing existing valid behavior.
Final Summary
Added the actionable startup warning for gRPC export with CA rotation but no reconnection period, with focused config warning coverage. Implementation SHA f35b6ab. Final integrated just check passed at 5b55617; exact-head CI run 33354208183 completed success.
