How can I continue?After more reviews become available, a review can be triggered using the 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.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head3e3fff0811d1d80c74b815f8cd9acb5f959d8960. -

RED: preserve only the focused upload-normalization regression on current protected main. The new contract requires one canonical basename helper and verifies that every converter source remains inside its request-scoped root.

정리 성공 후 작업 레코드를 삭제하세요.
cleanup_temp_dir()는 shutil.rmtree(..., ignore_errors=True)로 삭제 오류를 무시합니다. _cleanup_job()은 그 전에 store.delete(job_id)를 호출하므로, 디렉터리 삭제에 실패해도 레코드가 사라져 재시도할 수 없습니다. 삭제 성공 여부를 반환하거나 오류를 전달하고, 성공한 경우에만 store.delete(job_id)를 호출하세요.

실패한 정리 작업이 요청 처리와 작업 실행을 막지 않도록 분리하세요.
현재 정리 작업이 잘못된 요청에도 등록되고 _run_job보다 먼저 실행됩니다. _get_job_store(), list_jobs(), 또는 _now()에서 예외가 발생하면 후속 _run_job이 실행되지 않아 작업이 queued 상태로 남을 수 있습니다. 유효한 요청에만 정리를 등록하고 _run_job을 먼저 예약하거나, 정리 예외를 격리해 작업 실행을 보장하세요.

Problem
Upload filenames can contain Windows-style separators even when Codec Carver runs on POSIX. POSIX
Path(...).nametreats backslashes as ordinary characters, so a name such as..\\..\\etc\\passwdwas retained as one path-like filename instead of being normalized to the intended basename. Downstream code does not reinterpret those backslashes, so the prior behavior is not evidence of an escape frominput_dir; the defect is inconsistent, non-canonical filename handling across host platforms.Change
\\to/before applyingPath(...).namein single and batch upload paths;., and..names;Test-first evidence
The original branch added focused single and batch regressions. Review then identified that basename-only assertions could miss a future containment regression. Exact head
2abeab6c786ab4e4f4e4cd879859ce0acc13d53cnow assertssource.resolve().is_relative_to(root.resolve())as well as the expectedpasswdbasename, and corrects the security note.Acceptance boundary
Merge only after CI, fuzz, SAST, Security Scan, current-head automated review, zero valid unresolved threads, and live repository policy all apply to this unchanged head. Queued or predecessor evidence is not success.
