Replace .map(|f| f.build()) with .map(FileBuilder::build) at line 78 of diff_builder.rs to eliminate Clippy redundant_closure warning. Issue: #458
Document the HunkLine enum variants to clarify their role in unified diff format (Context=unchanged, Add=added, Remove=removed). This is the only undocumented item in diff_builder.rs — all public items were already properly documented by prior work.
…Option<PathBuf> to Option<&PathBuf> Use idiomatic Rust Option<&PathBuf> instead of &Option<PathBuf> for optional reference parameter. Call site updated to use config_path.as_ref() to convert Option<PathBuf> to Option<&PathBuf>. Work item: work-1ab603e1
Work item: work-a59eb6b6 Fixes: GitHub issue #472 - Add escape_md function to diffguard-types/src/lib.rs as pub fn - Update diffguard-core/src/render.rs to import escape_md from diffguard_types - Update diffguard/src/main.rs to import escape_md from diffguard_types - Remove duplicate escape_md implementations from both consumer crates The escape_md function escapes special Markdown characters (|, `, #, *, _, [, ], >) and line endings (\r, \n) for safe table cell inclusion. The diffguard-types version uses CRLF-first handling for correctness.
…iveEntry Extracted the inline field-merging logic from merge_false_positive_baselines into a dedicated fill_from method on FalsePositiveEntry. This improves: - Encapsulation: the field-merging behavior is now co-located with the data - Reusability: the method can be used in other contexts if needed - Readability: the merge function now reads more clearly at a higher level All 24 tests pass after this change.

HARDENED Gate: pr-maintainer-vision-agentIssue: checkstyle.rs:51: Severity::Info maps to 'warning' same as Warn — semantic bug What This Change DoesThis branch applies focused refactoring improvements to the Checkstyle XML renderer: extracting magic strings as named constants (, ), improving doc comments for clarity, and using inline format args. The core bug (Severity::Info → 'warning') was already fixed in commit b31d836 on main via PR #460. Vision AlignmentThe implementation approach matches the ADR's stated goals. The severity mapping fix is already on main, and the current refactorings align with the codebase's architectural direction: self-documenting code through named constants, modern Rust idioms (inline format args), and clear documentation. The codebase consistently uses this pattern in similar modules (sarif.rs, junit.rs). Scope FidelityNo scope changes — implementation stays focused on crates/diffguard-core/src/checkstyle.rs. Pure refactoring: constants, docs, inline args. No new features, no public API changes. Long-Term ImpactPositive. Named constants improve maintainability (easier to update XML version/declaration), clearer docs help future maintainers understand error_element's purpose, and inline format args align with modern Rust style and pass clippy. No technical debt introduced. PrecedentsSets a good precedent: fix the bug first (already done on main), then improve code quality separately. Behavior-preserving refactoring with focused commits. This is the right pattern. Confidence Assessmenthigh — Changes are focused and behavior-preserving, aligned with codebase conventions, and the severity fix itself was already reviewed and merged via PR #460. Verdictapproved — The refactoring improvements are sound and follow maintainer instincts for clean, self-documenting code. No scope creep. The one documentation concern (module doc example shows severity=warning) is low-severity. This is the last gate check before INTEGRATED. |

LEARNED Gate: devlt-tracker — work-c63431f3What This Work Item TrackedIssue #443 reported that Key Lessons LearnedThe bug was pre-fixed. The most significant finding from this run is that the conveyor created a work item for an issue that was already resolved. This caused 83 API calls and ~3.6M tokens of effort for a work item that required no implementation. The fix ( HARDENED was the longest gate at ~4 days. The CI failures on PR #884 were driven by scope creep — the PR accumulated 35 files (1,385 insertions, 119 deletions) including unrelated diff parser tests, LSP changes, and analytics changes. Only the DESIGNED was misapplied. The gate expects ADR, specs, and task list artifacts for a code change. When the code change is already merged, these artifacts are governance overhead with no software value. No meaningful ADR can be written for a decision that was already made and verified.
