Mar 2026 19:30:23 +0200 Subject: [PATCH 05/53] fix: implement CodeRabbit review feedback for DescriptionDiffAlignmentCondition - Extend AlignmentVerdict to standard agent output schema with decision, confidence, reasoning, recommendations, and strategy_used fields - Add _truncate_text() helper to sanitize inputs (max 2000 chars for description/diff, 200 for title) preventing prompt injection - Check provider.supports_structured_output before invoking to handle providers without function calling capability - Implement exponential backoff retry loop (3 attempts: 2s, 4s, 8s waits) with structured logging including latency_ms and attempt count - Add human-in-the-loop gating: confidence < 0.5 flags for manual review - Add comprehensive test coverage for truncation, retry logic, low confidence fallback, malformed output, and unsupported provider - Update docs/concepts/overview.md to clarify LLM use is opt-in and LLM-assisted conditions gracefully degrade on failure - Fix stale

Changes: - Add hidden HTML marker to violation comments with content hash () - Compute stable hash of violations based on rule_description, message, and severity (sorted for consistency) - Check existing PR comments before posting and skip if identical comment already exists - Fail open on duplicate check errors to avoid blocking legitimate posts - Add structured logging for duplicate detection Tests: - Hash computation stability (order-independent) - Hash uniqueness for different violations - Duplicate detection via hidden marker - Fail-open behavior on API errors - Skip posting when duplicate exists - Post proceeds when no duplicate found - Formatter includes/excludes marker based on content_hash parameter Fixes the issue seen in PR #62 where 3 identical back-to-back comments were posted due to webhook redeliveries with different X-GitHub-Delivery headers.

Recommended reviewers are automatically + assigned to the PR via the GitHub API. +- **PR risk assessment** -- `/risk` slash command posts a detailed risk + breakdown (size, sensitive paths, test coverage, contributor history, revert + detection, dependency changes, breaking changes, and matched Watchflow rule + severity).
