# Retry Handling Task

Task kind: bug
Goal (one primary outcome): Fix transient retry handling
Current behavior and evidence: A focused transport test reproduces two retries after a successful response.
Acceptance criteria:
- The retry loop stops after the first successful response.
- The existing output and exit behavior remain unchanged.
In scope (packages/files/surfaces): internal/transport retry implementation and tests
Out of scope: Authentication and endpoint discovery
Compatibility constraints: Preserve existing flags, JSON output, and exit codes
Interface impact (commands/flags/output/errors/exit codes/Schema): None
Safety or data-mutation constraints: No live service calls or external writes
Expected validation: Focused transport tests, race test, formatting, and full Go test suite
Known environment limitations: Live DingTalk service is intentionally not used
