You completed 67 included PR reviews in the past 7 days; at that activity level, included reviews refill at 1 review per hour. Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. 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.

WalkthroughAdds the ChangesFilesystem durability
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR adds native filesystem publication and expands CI and release-policy validation, but workflow checks can currently miss required jobs or suppressed command failures, Python 3.10 test collection can fail despite being supported, and containerized Linux probes may reject common filesystems; these issues should be fixed or explicitly accepted before merge.

In `@crates/graphforge-filesystem/src/lib.rs`:
- Around line 349-359: Update the Windows install_new_file_platform flow and its
delegated windows::install_new_file implementation to use an atomic Windows
no-replace rename API, preventing replacement of a destination created
concurrently. Remove the TOCTOU-based precheck if it is only used for this
guarantee, and revise the adjacent comment to describe the API-enforced
no-replace behavior.
In `@crates/graphforge-storage/src/filesystem_admission.rs`:
- Around line 274-291: Update native_probe_is_bounded_content_free_and_cleans_up
and every_injected_phase_is_typed_and_never_mutates_target to detect unsupported
filesystem classes and skip instead of asserting success when
classify_supported_local_volume_platform returns filesystem_class_unproven;
preserve assertions for supported filesystems.
- Around line 401-415: Update the Windows directory durability handling around
open_directory_handle so it does not use sync_all or FlushFileBuffers as
evidence that directory metadata is durable. Use a supported Windows mechanism
that explicitly provides directory durability, or mark directory durability
unsupported and propagate that result through the callers.
In `@scripts/ci/test-binding-release-candidate.py`:
- Around line 167-200: In scripts/ci/test-binding-release-candidate.py:167-200,
update job_needs to recognize only active job-level needs fields and update
job_runs_command to parse active run scalar content before matching complete
commands, excluding comments, nested content, and unrelated text. In
scripts/ci/test-ci-storage-policy.py:594-609, validate active runs-on fields and
bind both platform result expressions to the actual require-gates.sh invocation
rather than searching arbitrary job text.

624-641: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winConfirm the buffer size covers the full
FILE_RENAME_INFOstruct for short names.
buffer_bytesisoffset_of!(FILE_RENAME_INFO, FileName) + name_bytes.FileNameis declared as[u16; 1], so for a one-code-unit target name the buffer is exactlysize_of::<FILE_RENAME_INFO>(), and for an empty name it is smaller than the struct. The code then writes through a*mut FILE_RENAME_INFO. Callers validate component names today, so an empty name is not reachable, but the invariant is implicit.Add a lower bound to make the allocation always cover the struct.
