Predecessor provenance โ€” canonical source moved to #1612

  • protected base: develop@042b0c70531b229af3acbd0421a2f23098d848b3
  • latest observed predecessor head: 87310729796190c954f1d55bab24ddf62aa3bcf4 (CI ๋Œ€๊ธฐ 15)
  • lifecycle: Draft predecessor / do not use for new source writes or merge evidence
  • canonical stable successor: fix(security): stabilize exception-redaction successorย #1612 codex/sentinel-exception-logging-successor@b3a51ab1a16f24ed20597861f65ada2aea2f229f

Complete succession evidence

b3a51ab1... is the last source-valid commit before the repeated wait-only commits. The predecessor then advanced through CI ๋Œ€๊ธฐ 11โ€“15 while keeping the same tree f73ef52...; comparisons from the source-valid point through the latest observed head have zero effective file delta. #1612 therefore inherits the complete current security/source/test tree without dropping any valid delta.

The valid contract now owned by #1612 is the exception/logging leak repair: redaction-aware traceback handling, bounded propagated errors, bounded fixture-import failure logging, the focused secret-bearing exception/fixture failure regressions, and .jules/sentinel.md guidance against raw exc_info=True as a redaction mechanism.

Why this predecessor stays open

A repeated external writer kept creating no-op commits only to wait for CI, including CI ๋Œ€๊ธฐ 15 after this PR had already been explicitly instructed not to mutate the head while checks/review were pending. Repository search found no checked-in CI ๋Œ€๊ธฐ or --allow-empty implementation to repair locally. Chasing this moving SHA would continue invalidating exact-head evidence without changing the product.

Do not create more source or no-op commits on this predecessor. Fresh hosted checks and independent review belong on #1612's stable exact head.

Do not close #1591 yet. Close only after #1612 normally integrates into protected develop, or another verified successor fully inherits every valid source/test/fixture/contract/evidence delta and protected-tree equivalence is audited. No force push, destructive rebase, dummy commit, self-approval, synthetic status, review dismissal/fabrication, admin bypass, or gate weakening.

๐Ÿ“ Walkthrough

Walkthrough

Changes

The change adds redaction-aware exception logging across API, LLM, fixture-import, IMAP, and POP3 paths. It removes sensitive exception messages from logs and propagated errors while preserving traceback frames and existing failure behavior. Regression tests cover these boundaries.

Exception logging and error handling

Layer / File(s) Summary
Redaction helper and validation
backend/core/safe_logging.py, backend/tests/test_safe_logging.py, backend/tests/test_exception_logging_boundaries.py
redacted_exception_info preserves traceback frames and replaces exception details with a fixed marker. Tests verify that secret values are absent from formatted logs while traceback function names remain present.
API and LLM error handling
backend/api/emails.py, backend/api/prompts.py, backend/services/llm_service.py, backend/tests/test_exception_logging_boundaries.py, backend/tests/test_email_exception_context.py
API and LLM handlers use redacted exception metadata or generic messages. Generic HTTP and service errors suppress exception chaining.
Fixture import and mail worker logging
backend/import_fixtures.py, backend/scripts/import_fixtures.py, backend/services/imap_worker.py, backend/services/pop3_worker.py, backend/tests/test_exception_logging_boundaries.py
Fixture paths use bounded log messages. IMAP and POP3 paths use redacted exception metadata. Rollback, return, synchronization, and data construction behavior remain unchanged.
Exception disclosure guidance
.jules/sentinel.md
The security note recommends redacted_exception_info(e), explains that raw exc_info=True does not redact messages, and prohibits exception interpolation in propagated messages.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: โšช Minimal ยท up to b3a51

This change redacts exception details while retaining traceback frames and returns generic errors for affected API and service failures. The supplied current-head coverage supports the intended behavior, with no actionable merge-blocking risk identified.

In `@backend/api/emails.py`:
- Line 776: Make exception logging redaction-aware for the email handler at
backend/api/emails.py:776, prompt handler at backend/api/prompts.py:119, and LLM
handlers at backend/services/llm_service.py:84, 150, 192, and 214 by applying
the projectโ€™s configured exception-redaction policy while preserving traceback
details. Add a regression test using a secret-bearing exception to verify
secrets are absent from logged output, and update .jules/sentinel.md:144 to
document that exc_info=True retains exception details and requires redaction.

In `@backend/import_fixtures.py`:
- Line 41: Replace exc_info=True with bounded, non-sensitive error logging in
every affected handler: backend/import_fixtures.py lines 41-41, 59-59, 97-100,
and 107-107, plus backend/scripts/import_fixtures.py lines 46-46 and 74-75.
Update the exception handling around the fixture import and parsing flows to log
only a concise safe error summary, without raw tracebacks, file paths, OS
errors, or provider details.
- Line 41: Add regression tests for the failure paths in the fixture import flow
covering parse, body embedding, attachment embedding, and commit failures.
Assert each pathโ€™s return value, attachment handling, rollback behavior, and
that the corresponding changed logger.error call records exc_info=True.

@seonghobae Reviewed 03e0f480479fbf6cdb73f7c2d9dd5335b68513ce against 042b0c70531b229af3acbd0421a2f23098d848b3.

I found no new review findings.

The .jules/sentinel.md correction from 3d8efcd... is retained. It correctly requires core.safe_logging.redacted_exception_info(e) and rejects raw exc_info=True as a redaction method.

The reviewed head does not reintroduce exception chaining of secret-bearing provider errors. The new LLMServiceError and prompt HTTPException paths use from None.

The fixture-import failure logs use bounded generic messages. They do not include fixture paths, attachment filenames, message IDs, or exception text.

The prompt error path has no sensitive prompt-context logging regression.

No focused tests were deleted. The range adds backend/tests/test_exception_logging_boundaries.py and backend/tests/test_safe_logging.py, including regression coverage for redaction, exception chaining, and fixture-import logging.

This verdict is independent of predecessor review verdicts.

Learning: In ContextualWisdomLab/naruon PR `#1591`, `.jules/sentinel.md` must not describe raw Python logging `exc_info=True` as secure redaction. Raw `exc_info=True` formats the exception value. Documentation must require `core.safe_logging.redacted_exception_info(exc)` or the configured equivalent when traceback frames are retained.

Learning: In `backend/import_fixtures.py` and `backend/scripts/import_fixtures.py`, fixture-import failure logging must emit bounded generic operation messages only. Do not use `exc_info=True`, raw tracebacks, exception text, fixture paths, attachment filenames, OS errors, or provider details because the default logger has no redaction boundary. Regression tests for parse, body-embedding, attachment-embedding, and commit failures must preserve existing return, attachment, and rollback behavior while proving secret-bearing and path-bearing exception text is absent from log records.

Timestamp: 2026-09-07T14:59:37.305Z
Learning: In this repository, `AGENTS.md` forbids secret-derived values in log output and raised exception text. Python logging with `exc_info=True` formats the exception value and is not a redaction mechanism. Exception handlers must use `core.safe_logging.redacted_exception_info()` or the configured equivalent when preserving traceback frames.

@seonghobae Reviewed exact head 89158d6e8ccbfa6c138c1e9bb7a2b56e0d85e9e0 against protected base 042b0c70531b229af3acbd0421a2f23098d848b3.

I found no new review findings.

Git ancestry confirms that 03e0f480479fbf6cdb73f7c2d9dd5335b68513ce is the direct parent of the requested head. The descendant-only diff removes the unused base64 import from backend/tests/test_safe_logging.py. The redaction regression test remains unchanged in behavior.

The requested head retains the .jules/sentinel.md correction. It requires core.safe_logging.redacted_exception_info(...) and states that raw exc_info=True does not redact exception messages.

The reviewed LLM and prompt error paths use redacted traceback logging. They raise bounded errors with from None. The fixture-import paths retain bounded generic failure logs and preserve attachment, rollback, and return behavior.

This result is based on an independent source review of the specified base and exact head. It does not transfer predecessor approval or hosted evidence.

No predecessor review verdict should be transferred.

I have verified that the current exact head 03e0f480479fbf6cdb73f7c2d9dd5335b68513ce retains the .jules/sentinel.md correction and successfully restores the missing tests in backend/tests/test_exception_logging_boundaries.py. The regressions involving exception-chaining (e.g. raise LLMServiceError(...) from e), concrete fixture identifiers, and prompt contexts are fully resolved and absent. All 72 localized exception boundary and integration tests pass cleanly, confirming that no sensitive strings or file paths leak into logs or propagated exceptions.

@seonghobae Reviewed exact head 4d6e2b869fd51da96cb565408caf0e920263e57b against protected base 042b0c70531b229af3acbd0421a2f23098d848b3.

I found one security issue.

P1 โ€” Suppress the exception chain in the email endpoint.
backend/api/emails.py Line 778 raises HTTPException from within except Exception as e without from None. Python retains e as HTTPException.__context__. If an error formatter or reporting integration renders the chain, it can disclose the original exception text after the redacted log entry.

Use from None for this propagated generic error:

raise HTTPException(
    status_code=500,
    detail="An internal error occurred while sending the email",
) from None

The requested head retains the valid .jules/sentinel.md correction. It correctly states that raw exc_info=True does not redact exception values. The redacted traceback helper preserves traceback frames and replaces the exception value with "Exception details redacted".

The LLM and prompt failure paths use generic errors with from None. The fixture-import failure paths retain bounded generic messages. The focused security tests remain present. backend/tests/test_safe_logging.py has the same blob as the reviewed 89158d6e8ccbfa6c138c1e9bb7a2b56e0d85e9e0 head, so the temporary base64 import regression is absent.

Learning: In ContextualWisdomLab/naruon PR `#1591`, `.jules/sentinel.md` must not describe raw Python logging `exc_info=True` as secure redaction. Raw `exc_info=True` formats the exception value. Documentation must require `core.safe_logging.redacted_exception_info(exc)` or the configured equivalent when traceback frames are retained.

Learning: In `backend/import_fixtures.py` and `backend/scripts/import_fixtures.py`, fixture-import failure logging must emit bounded generic operation messages only. Do not use `exc_info=True`, raw tracebacks, exception text, fixture paths, attachment filenames, OS errors, or provider details because the default logger has no redaction boundary. Regression tests for parse, body-embedding, attachment-embedding, and commit failures must preserve existing return, attachment, and rollback behavior while proving secret-bearing and path-bearing exception text is absent from log records.

Timestamp: 2026-09-07T14:59:37.305Z
Learning: In this repository, `AGENTS.md` forbids secret-derived values in log output and raised exception text. Python logging with `exc_info=True` formats the exception value and is not a redaction mechanism. Exception handlers must use `core.safe_logging.redacted_exception_info()` or the configured equivalent when preserving traceback frames.

@seonghobae Reviewed exact head b3a51ab1a16f24ed20597861f65ada2aea2f229f against protected base 042b0c70531b229af3acbd0421a2f23098d848b3.

I found no new review findings.

backend/api/emails.py restores the required exception-context boundary. The generic handler logs with redacted_exception_info(e) and raises the bounded HTTPException with from None. The new backend/tests/test_email_exception_context.py verifies __suppress_context__, no explicit cause, and no sensitive provider text in rendered exception output.

backend/core/safe_logging.py retains traceback frames and replaces the logged exception value with the stable redacted marker. The prompt and LLM error paths retain bounded errors with from None. The fixture-import paths retain bounded generic failure messages without exception text, fixture paths, attachment filenames, or message identifiers.

.jules/sentinel.md retains the correct guidance that raw exc_info=True does not redact exception values.

This result uses an independent source review of the requested head. It does not use predecessor approvals, CI-wait commits, or hosted-check evidence. I used the repository guidance on redacted exception logging and bounded fixture-import logs.

Learning: In ContextualWisdomLab/naruon PR `#1591`, `.jules/sentinel.md` must not describe raw Python logging `exc_info=True` as secure redaction. Raw `exc_info=True` formats the exception value. Documentation must require `core.safe_logging.redacted_exception_info(exc)` or the configured equivalent when traceback frames are retained.

Learning: In `backend/import_fixtures.py` and `backend/scripts/import_fixtures.py`, fixture-import failure logging must emit bounded generic operation messages only. Do not use `exc_info=True`, raw tracebacks, exception text, fixture paths, attachment filenames, OS errors, or provider details because the default logger has no redaction boundary. Regression tests for parse, body-embedding, attachment-embedding, and commit failures must preserve existing return, attachment, and rollback behavior while proving secret-bearing and path-bearing exception text is absent from log records.

Learning: In this repository, `AGENTS.md` forbids secret-derived values in log output and raised exception text. Python logging with `exc_info=True` formats the exception value and is not a redaction mechanism. Exception handlers must use `core.safe_logging.redacted_exception_info()` or the configured equivalent when preserving traceback frames.
