Deletion Log

2026-03-03 feature polish

Scope: backend/src/v1/agent/* and backend/tests/unit/v1/agent/* only.
Candidate review source: scoped refactor-cleaner run for the directories above.

Merged duplicated newline validation logic in backend/src/v1/agent/service.py.
- Before: duplicated checks in prepare_resume, stream_run, stream_resume.
- After: centralized _validate_no_newlines helper.
- Behavior impact: none (same validation semantics).
Merged duplicated SSE event string formatting in backend/src/v1/agent/service.py.
- Before: repeated f"data: {json.dumps(...)}\n\n" fragments.
- After: centralized _sse_data helper.
- Behavior impact: none (same payload format).

backend/src/v1/agent/crewai_flow.py
- Reason: candidate report suggested possible dead code, but no deletion was done in this polish pass because cross-module usage certainty was insufficient.
Legacy run() path in backend/src/v1/agent/service.py
- Reason: potentially still relied on by non-scope code paths; deletion deferred.
