preserve(security): route duplicate temporal log-forging finding to #1055 - #1261

Conversation
🚨 Severity: MEDIUM 💡 Vulnerability: Python `logger` statements used immediate f-string interpolation with untrusted input (`path_str`). An attacker could supply a filename with newline characters (`\n`) to inject fake log entries, obscure malicious activity, or break automated log parsers (CWE-117: Improper Output Neutralization for Logs). 🎯 Impact: Attackers can forge logs, making incident response difficult and potentially triggering false positives in monitoring systems. 🔧 Fix: Refactored `logger.info`, `logger.warning`, and `logger.error` statements in `services/analysis-engine/src/bandscope_analysis/temporal/analyzer.py` and `services/analysis-engine/src/bandscope_analysis/cli.py` to use deferred string formatting (`%s`) and wrapped the untrusted `path_str` in `repr()` to escape control characters like newlines safely. ✅ Verification: Ran `cd services/analysis-engine && uv run pytest` and verified all tests pass without regressions.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Remove the generated repr(path)/raw-exception logging implementation from the active diff. Canonical #1055 already owns the stronger path-free log sink and a stronger caplog regression that covers decoder failure without disclosing the selected local path. Keep the generated finding in ancestry for provenance until protected succession satisfies PR-0. Signed-off-by: Seongho Bae <me@seonghobae.me>

Preservation / single-writer status
This generated Sentinel PR found a valid CWE-117 class, but it is not a second TemporalAnalyzer/CLI source owner.

The weaker generated implementation is not canonical:
repr(path_str)prevents raw CR/LF interpolation but still discloses the selected local path, and logging%sfor the caught exception still renders decoder-controlled exception text. Canonical #1055 is deliberately stricter: generic path-free selected-local-audio context plus exception type only, while #1237 separately preserves the broken-__str__/ bounded caller-visible diagnostic evidence.Fresh parallel-writer recurrence and repair

repr(path_str)on load/failure and rendered the caught exception in the failure sink; the CLI also recreated temporal-probe logging. Those deltas are weaker than #1055's path-free/no-temporary-probe orchestration contract, while the formatter delta belongs to #1176.Ordinary descendant

The branch ref advanced withforce=false; all intervening generated history remains ancestry. This lane therefore owns no current temporal, CLI, sentinel-policy, formatter, or product source.Fresh exact-head workflow generation exists but is nonterminal: CodeQL is pending; repository CI, SBOM, build-baseline, Semgrep and Security Scan are queued. No predecessor checks/reviews transfer across the source movement.
PR-0 / closure rule
Keep Open / Draft until #1055 or a verified successor absorbs every still-valid #1211/#1237 diagnostic regression, preserves the path-free sink and no-temporary-CLI-probe contract, obtains fresh exact-head repository/security/SAST/SBOM/CodeQL evidence plus qualifying independent non-author approval, and reaches protected ancestry. Only then may this zero-delta provenance PR be closed unmerged as fully succeeded.
No self-approval, force-push, destructive rebase, raw/escaped path logging, decoder-text logging, duplicate temporal source, copied #1176 formatter source, gate weakening, blind rerun, no-op freshness commit, synthetic status, predecessor-evidence transfer, or premature Close.
