Problem

persistAttemptLogs cloned potentially large request and response bodies even when the API key had no_log=1. saveCallLog discarded those clones later, so no-log traffic paid the allocation/GC cost with no persisted detail.

Change

• Short-circuit the two bounded-clone paths for noLogEnabled before traversing payloads.
• Keep the existing counters, audit handling, and normal (non-no-log) detailed logging unchanged.
• Add focused regression coverage with a no-log payload that throws if cloned.

Production evidence

An observed Nov 1 pressure incident involved 59 successive 50K–174K-token OpenAI Responses requests from a single no-log API key. The Node process entered pressure with ~1.2 GiB V8 heapUsed. This change removes a demonstrably redundant copy step; it does not claim to resolve every source of heap growth.

No production deployment included in this contribution.

Summary

Summary by CodeRabbit

• Bug Fixes
  • When request and response logging is disabled, call logs now omit both bodies while retaining call status, detail state, and token counts. This also prevents disabled request-body logging from accessing the body.
  • Call-log saves continue to emit lifecycle events asynchronously.

When noLogEnabled is true, attempt logging stores null request and response bodies. A new test checks that the saved call-log row retains its status and input-token usage.

Changes: Attempt logging

Layer / File(s)	Summary
No-log body persistence open-sse/handlers/chatCore/attemptLogging.ts, tests/unit/chatcore-attempt-logging.test.ts	When noLogEnabled is true, request and response bodies are stored as null. The test checks that the saved row retains status 200, detail state none, and 125,000 input tokens.

Merge Risk: Moderate · previous review 8f0ac

The no-log optimization is sound, but the added regression test asserts a field that does not exist on the returned rows and will fail, so the unit suite will not pass as submitted. No-log responses also lose some reasoning-related metadata. Fix the test assertion before merging; the metadata gap is a minor follow-up.

Security architecture risk: Minimal · up to 8f0ac

The existing no-log protection remains enforced, and the change removes redundant payload preparation without introducing a new endpoint or additional authority. Usage counters and persistence ordering remain intact. Some response-derived reasoning diagnostics can disappear for no-log calls.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The change affects existing no-log traffic through the shared attempt logger. It removes two payload-copy paths, reducing allocation work in the serving process without adding a network entrypoint, credential capability or cross-key access path.

Trust Boundaries and Controls

• observed — The caller derives noLogEnabled from API-key metadata and passes it alongside the key identity. The sink enforces no-log when either the supplied flag or its key-policy lookup requires it; the new early omission does not replace that independent control.

PASS. Both commits contain only human-authored subjects and standard author/committer fields. Neither commit has a Co-Authored-By trailer or an AI-generated footer. The PR body contains no Co-Authored-By trailer naming an AI assistant or bot and no “Generated with <AI tool>” footer.

Full details: Description check

Explanation

The description explains the problem, change, regression coverage, incident context, and deployment scope. It does not follow the required template because it omits the Summary, Related Issues, Target Branch, Validation, Tests Added Or Updated, Coverage Notes, and Reviewer Notes sections.

Resolution

Rewrite the description using all required template headings. Add the related issue status, target-branch checklist, validation results, changed test file, coverage notes, and reviewer notes. Retain the existing problem, change, production evidence, and deployment information under the appropriate sections.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Line 611: Update persistAttemptLogs so the successful non-streaming path
computes scalar reasoning observations from the response before noLogEnabled
suppresses responseBody, then passes those observations through the existing
metadata path used by buildCallLogRow. Preserve opaque-reasoning detection and
readable-character counts without cloning or persisting the response payload;
keep usage-derived reasoning unchanged.

Review comments at @tests/unit/chatcore-attempt-logging.test.ts:
- Line 337: Update the assertion in the getCallLogs test to read the input token
count from the returned tokens.in field instead of tokensIn, while preserving
the expected value.
