fix(#2411): post medium+ findings as file-level comments when line is outside diff hunk - #2415
Conversation
… outside diff hunk The review agent was dropping Medium+ severity findings from inline PR comments when their referenced line fell outside a diff hunk, even when the file was in the PR diff. This made the most important findings less visible than Low-severity ones. Changes to findingsToReviewComments() in postreview.go: - Medium+ findings (critical, high, medium) whose file is in the diff but line is outside any hunk now fall back to file-level comments (subject_type: "file") instead of being silently dropped. This uses the GitHub PR review API's file-level comment feature. - Info-severity findings are now filtered from inline comments entirely, per #2287. - Low-severity findings outside diff hunks continue to be dropped as before. Supporting changes: - Added SubjectType field to forge.ReviewComment and wired it through the GitHub API client payload. - Added isMediumPlusSeverity() helper for severity classification. - Added logging for info-filtered and file-level fallback counts. - Added tests for info filtering, file-level fallback, and severity classification. Pre-existing test failures in TestStartFetchService_* (unrelated to this change). Pre-commit could not run due to sandbox network restrictions on shellcheck install. Closes #2411

/fs-fix I think this should do this for all findings, not just medium+. Rather, we shouldn't hardcode special handling for medium+. Instead, we should defer to #2341 where a var will be introduced to control what severity items are surfaced vs not. I like the change here to make sure file-level comments are posted when the line is outside the diff hunk, but don't discriminate amongst the severity levels here. |

…lback Per human feedback on PR #2415: all findings whose line is outside a diff hunk now fall back to file-level comments, not just medium+. Removed isMediumPlusSeverity() helper and info-severity filtering — severity-based filtering will be handled by a separate configuration variable introduced in #2341. Addresses review feedback on #2415
🔧 Fix agent — iteration 1 (human-triggered)Removed all severity-based discrimination from findingsToReviewComments per human instruction. All out-of-hunk findings now fall back to file-level comments. Removed isMediumPlusSeverity() helper and info-severity filtering. Severity filtering deferred to #2341. Fixed (2):

[medium] logic-error
File-level fallback comments lose the original line number. When a finding falls back to a file-level comment (SubjectType="file", Line=0), formatFindingComment(f) renders severity, category, description, and remediation but NOT the original line number. Since file-level comments have no line annotation on the PR, reviewers cannot locate which line the finding refers to.
Suggested fix: In the file-level fallback branch, include the original line number in the comment body, e.g., prepend fmt.Sprintf("Line %d — ", f.Line) to the body.
| // When SubjectType is "file", the comment is attached to the file as a | ||

[medium] architectural-violation
SubjectType field uses GitHub-specific vocabulary ("file" maps to GitHub's subject_type API parameter) in the forge-neutral interface struct. The value is hardcoded in internal/cli/postreview.go, outside the GitHub forge implementation.
Suggested fix: Move subject_type logic into the GitHub client by detecting Line==0 and setting subject_type internally, keeping ReviewComment forge-neutral.

/fs-fix Two things need changes. I've +1'd the bot's inline comments for details.
formatFindingComment doesn't include the original line number. File-level comments have no line annotation in the GitHub UI, so reviewers can't find the issue. Include f.Line in the comment body for file-level fallbacks.
SubjectType on forge.ReviewComment is GitHub-specific vocabulary. The GitHub client can infer subject_type: "file" from Line == 0 internally — keeps the forge struct clean and follows our forge abstraction rules.
Non-blocking: PR title still says "medium+" but the code handles all severities now.

[critical] scope-misalignment
The PR description claims three severity-based behaviors (medium+ file-level fallback, info filtering per #2287, low findings dropped outside hunks) but the implementation applies file-level fallback to ALL severities without any severity check. The isMediumPlusSeverity() helper claimed in the PR body does not exist in the diff or anywhere in the repository. The tests explicitly confirm all severities fall back identically.
Suggested fix: Either add severity-based branching (filter info findings, drop low out-of-hunk findings, file-level fallback only for medium+) or correct the PR title and description to accurately state that all severities now get file-level fallback.
