Summary

Surviving OpenCode suggested diffs that remove more than one current-head line still posted as a single-line comment, so GitHub Apply suggestion only replaced the first line.

  • When the suggested_diff removes N>1 lines and every line from the finding through that span sits on the same current-head hunk, set start_line, line, and start_side.
  • A range that would leave the hunk stays single-line so GitHub does not 422.
  • Includes fix(review): turn surviving suggested diffs into GitHub suggestions #972 so this branch can land independently.

#954/#968#972 remain MERGEABLE with auto-merge; they are blocked by the two-approval ruleset, not a current-head code fail.

Test plan

  • pytest tests/test_opencode_inline_comment_fallback.py tests/test_opencode_agent_contract.py — 65 passed
  • coverage run -m pytest tests --ignore=tests/test_strix_quick_gate.sh — 1002 passed, 100% statements/branches, interrogate 100%
  • Current-head required checks on this PR

When GitHub refuses inline review comments, the PR-level fallback now
lists each sanitized current-head finding location instead of a generic
sentence. Suggested diffs stay out of the body.
Rebuild the fallback from gh api stderr after a refused attach so the
OpenCode overview keeps each trusted path:line next to the GitHub 422
phrase instead of a location-only list.
A single invalid path:line 422s the whole comments array. After that
failure, split the payload and retry each comment so surviving hunks
still attach; remaining failures keep the overview receipts.
The publisher moved that phrase out of the workflow YAML, so the
exact-head path-policy harness failed looking in the old file.
When some one-at-a-time inline comments attach and others 422, the
overview must list only the refused locations so attached hunks are
not reported as failed.
Mixed one-at-a-time retries can fail for different reasons. Record
path:line plus that comment's gh api error so the overview does not
reuse one shared sentence for every refused hunk.
Unbounded one-at-a-time retry after a batch 422 can thrash GitHub,
and mixed receipts listed only refused locations. Cap retries at 20,
persist attached path:line beside refused ones, and record leftovers
the cap left untried so the overview shows every outcome.
GitHub 422s review comments that sit outside every current-head @@ hunk.
Filter the payload against git diff --unified=3 first, post only the
on-hunk comments, and persist skipped path:line as overview receipts.
Authors could not one-click apply OpenCode inline repairs because the
payload only posted ```diff fences. Convert + lines from those diffs
into ```suggestion blocks on surviving RIGHT-side hunk comments.
A surviving suggested_diff that removes more than one current-head line
still posted as a single-line comment, so Apply suggestion only replaced
the first line. Set start_line, line, and start_side when the full span
sits on the same hunk; leave off-hunk spans single-line to avoid 422.

@cwl-noema-review Please review the current head. Set start_line/line/start_side on surviving multi-line GitHub suggestions when the full span sits on one current-head hunk.

Review Change Stack

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 91 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

OpenCode 인라인 댓글 처리가 변경되었습니다. 변경 hunk 밖 댓글을 제외하고, 배치 422 오류를 개별 재시도합니다. 각 결과를 receipt로 기록하고 fallback 본문에 반영합니다. GitHub suggestion과 다중 라인 범위도 지원합니다.

Estimated code review effort: 5 (Critical) | ~120 minutes

Mergeability Score: 🟡 Moderate · up to 540db

Multi-line suggestions can still be retried or recorded against the span’s last line instead of the finding’s actual line, and rejected suggestions may provide no usable location to the author. Merge should wait for the anchor and receipt handling to be corrected.

Comment @coderabbitai help to get the list of available commands.

GitHub needs side together with start_line/line/start_side so a
multi-line apply replaces the whole hunk span. A 422 substring in a
SHA or issue number no longer starts one-at-a-time retry.

A multi-line GitHub suggestion that already has start_line/start_side
must keep that range when the batch 422 path retries one comment at a
time. Dropping the range posts a single comment on the last line.
