Consolidation integration: CI repairs for gpu-only builds, checksum guard, and dogfood lane - #173
Conversation
- phase1_admission: drop the simd-only gate from simd_phase2_tail_absence_for; the gpu-region caller compiles under --features gpu without simd and only reads plain admission vectors, so gpu-only and portable,gpu builds failed with E0599. - checksum guard: bind the validator prefixes the 0.5.81 detector families added (glimt-, glptt-, glsoat-, slack app/config, shopify, square, jwt eyJ) to their authoritative detectors; the guard fails closed on any unbound catalog prefix. - dogfood: docs/src/workflows/github-action.md documents exact Action version pins of this public repository, and generic entropy reads a pinned release tag as a credential-shaped token; suppress the file in the normal dogfood lane with a governed reason.

📝 Info: Dead-code exposure on portable release builds
Removing the simd gate makes simd_phase2_tail_absence_for always compile, but its only caller scan_coalesced_phase2_with_admission stays gated to simd/gpu/test. A portable release build without those features leaves it callerless, which can raise a dead_code warning. The scanner crate does not deny(warnings), so no build break, but the CI-repair intent makes it worth confirming the portable lane stays clean.

…npack budget The image-wide --limit-docker-tar-total-bytes guard exists to bound EXTRACTED layer content, but validate_docker_archive_plan charged the container's own blob sizes too, so a layer blob large enough on its own tripped the guard before any layer entry was measured and the refusal named a content digest instead of the offending entry. Whether it tripped depended on how the producing docker version laid out the archive. The outer pass now validates structure and per-entry caps without charging the budget; every layer validation still charges it, so cumulative accounting across layers is unchanged.
…he image budget Refines the outer-pass accounting: manifest.json and other scanned metadata still spend the image-wide budget, while entries under blobs/ are skipped there because a layer blob is re-read and accounted through its extracted entries. Charging the packaged layer size instead tripped the guard on the container before any layer content was measured, which named a digest and defeated the KH-196 contract that the refusal names the entry it stopped at.

📝 Info: Outer pass skips budget pre-check for metadata entries
With charge_image_budget=false, validate_docker_archive_plan at archive.rs skips the cumulative-byte check entirely, yet extract_docker_archive_entries still charges non-blob metadata entries (archive.rs). The validate-before-write guarantee no longer covers those entries, so extraction can write some entries before hitting the budget. Low impact: outer metadata is small and the raw tar has no amplification.

🔍 blobs/ exemption is OCI-layout specific
The exemption at archive.rs only matches layer blobs under blobs/ (OCI layout). Legacy docker save layouts store layers at <layerid>/layer.tar, which are not exempted, so those blobs get charged in the outer pass and again when streamed. This is not a regression since the prior code always charged, but the fix only helps OCI-layout images. A ./-prefixed entry path would also bypass the match.

📝 Info: simd gate removal restores accessor consistency
Removing the simd cfg gate is correct. The caller scan_coalesced_phase2_with_admission is gated #[cfg(any(feature = "simd", feature = "gpu", test))], so a gpu-only build referenced a method that was not compiled. The method reads only plain admission vectors and its sibling accessors (e.g. direct_scan_absence_for) are already ungated.

…ging syncs on Windows The action-e2e lockdown lane failed because every machine with execution packs installed under <cache>/keyhog/execution-packs tripped the past-findings gate: the gate trusts only compiled cache filenames among direct children of the cache root. A directory named execution-packs is now trusted there; any other entry still fails closed. On Windows the pack compiler's staging fsync opened the stage directory in read mode; FlushFileBuffers requires a write-mode handle, which needs FILE_FLAG_BACKUP_SEMANTICS. The Windows branch now opens with that flag.

Microsoft FlushFileBuffers GENERIC_WRITE access directory handle FILE_FLAG_BACKUP_SEMANTICS Rust File sync_all Windows
💡 Result:
On Windows, the FlushFileBuffers function is designed to flush buffered data for a specified file or volume [1][2]. Official Microsoft documentation does not include directory handles in the list of valid handles for FlushFileBuffers [1][3], and attempting to use it on a directory handle typically fails [4][5]. Key Technical Points: 1. Handle Compatibility: While you can open a directory handle using the FILE_FLAG_BACKUP_SEMANTICS flag in CreateFile [6][3], this handle is intended for specific operations like BackupRead, BackupWrite, and retrieving metadata [3]. It is not a supported target for flushing operations via FlushFileBuffers [4][5]. 2. FlushFileBuffers Requirements: This function requires a handle opened with GENERIC_WRITE access [1]. Even if a directory handle is opened with GENERIC_WRITE, calling FlushFileBuffers on it is not guaranteed to work and often results in errors such as ERROR_INVALID_HANDLE or invalid device requests depending on the file system and drive type [1][4]. 3. Rust File::sync_all: In Rust's standard library, the sync_all method on a File object is implemented to sync file content and metadata to disk [7][8]. Because FlushFileBuffers is not a viable mechanism for syncing directory contents on Windows, Rust's std::fs implementation does not (and cannot) perform directory-level syncing via this function [9]. If you need to ensure the durability of file operations (such as renames or creations) within a directory on Windows, simply flushing the directory handle is generally not effective [10][4]. For developers, if your goal is to ensure the durability of file system changes, note that Windows handles file system metadata durability differently than POSIX-based systems [4]. You generally need to ensure the file itself is flushed or opened with FILE_FLAG_WRITE_THROUGH [2][10]. There is no standard, reliable system call to "fsync" a directory on Windows to guarantee the persistence of directory entry changes [4][5].

site:learn.microsoft.com FlushFileBuffers directory handle ERROR_INVALID_HANDLE GENERIC_WRITE
💡 Result:
The FlushFileBuffers function is designed to flush the internal buffers of a file, communication device, or named pipe to the physical medium [1][2]. The function explicitly requires a handle that has been opened with the GENERIC_WRITE access right [1]. While a directory handle can be obtained using CreateFile with the FILE_FLAG_BACKUP_SEMANTICS flag [3], FlushFileBuffers is generally not intended for use with directory handles. When FlushFileBuffers is called on a handle that does not support the operation—such as a console output handle or other handle types where flushing is not defined or applicable—the function returns FALSE and GetLastError typically returns ERROR_INVALID_HANDLE [1]. If you are attempting to ensure that file system metadata changes (such as file creation, renaming, or timestamp updates) are committed to disk, FlushFileBuffers should be called on the specific file handle rather than the directory handle [1][4]. Alternatively, if you need to avoid the performance overhead of manual flushes, you can open files with the FILE_FLAG_WRITE_THROUGH flag, which requests that the system write through any intermediate cache to the disk [5][4].

site:github.com/rust-lang/rust library/std/src/sys/fs/windows.rs sync_all FlushFileBuffers
💡 Result:
In the Rust standard library's Windows implementation, located at library/std/src/sys/fs/windows.rs (or the corresponding location in the current repository structure), the sync_all method is implemented by calling the Windows API function FlushFileBuffers [1][2][3][4]. The implementation is defined as follows: pub fn fsync(&self) -> io::Result<> { cvt(unsafe { c::FlushFileBuffers(self.handle.as_raw_handle) })?; Ok() } pub fn datasync(&self) -> io::Result<> { self.fsync } Key details include: 1. Relationship to Sync: The sync_all method maps directly to fsync, which invokes the Win32 FlushFileBuffers function [1][4]. As seen in the source code, datasync is also implemented by calling the same fsync method [1][4]. 2. FlushFileBuffers: This is a Windows API function that flushes the buffers of a specified file handle to disk, ensuring that all buffered data is written to the physical storage device [5]. 3. Rust's File::flush: It is important to distinguish this from the standard library's File::flush method, which is a no-op (it does nothing) on both Windows and Unix platforms for file types because file handles do not have internal user-space buffers [1][4][6]. The synchronization of data to disk is instead handled by explicit methods like sync_all [6].

Windows NTFS FlushFileBuffers directory handle GENERIC_READ GENERIC_WRITE FILE_FLAG_BACKUP_SEMANTICS works
💡 Result:
Using FlushFileBuffers on a directory handle, even when opened with FILE_FLAG_BACKUP_SEMANTICS, is not supported and does not provide a reliable way to flush directory metadata to disk on Windows [1][2]. While you can successfully obtain a handle to a directory by using CreateFile with the FILE_FLAG_BACKUP_SEMANTICS flag [3][4], passing that handle to FlushFileBuffers generally fails [1]. Official documentation for FlushFileBuffers specifies that it operates on handles to files, communications devices, or the server end of named pipes [5]. Although some users have observed that it may sometimes succeed or appear to flush on specific file systems (such as FAT) as a side effect of how the underlying driver behaves, this is not a documented or guaranteed behavior for NTFS or other modern Windows file systems [6]. On Windows, there is no direct equivalent to the POSIX fsync on a directory handle [1][2]. If you require durability for file system operations, you should: 1. Use FlushFileBuffers on the handle of the specific file you have modified [5][7]. 2. If you need to ensure an entire volume is flushed, FlushFileBuffers can be called on a volume handle, though this requires administrator privileges [6][2]. 3. For kernel-mode operations, the Windows Driver Kit (WDK) provides functions like NtFlushBuffersFileEx, which offer more granular control over flushing file data and metadata, but these are intended for driver development and not standard user-mode applications [8]. In summary, attempting to use FlushFileBuffers on a directory handle is not a standard or reliable practice for ensuring data integrity on NTFS [1][2].

site:github.com directory FlushFileBuffers FILE_FLAG_BACKUP_SEMANTICS GENERIC_WRITE Windows
💡 Result:
On Windows, calling FlushFileBuffers on a handle to a directory is not a supported or reliable way to synchronize directory metadata to disk [1][2][3]. To obtain a handle to a directory, you must call CreateFile with the FILE_FLAG_BACKUP_SEMANTICS flag [4][5]. While it is technically possible to pass a directory handle opened with GENERIC_WRITE access to FlushFileBuffers without the function returning an error, this does not perform a synchronization of the directory's contents or metadata in the way that the POSIX fsync on a directory does on other operating systems [6][2][3]. Key technical observations: 1. Requirement for Handle Access: If you attempt to call FlushFileBuffers on a directory handle that was opened with only GENERIC_READ access, the call will fail with ERROR_ACCESS_DENIED [6]. It requires GENERIC_WRITE access to succeed [6]. 2. Lack of Equivalent Functionality: Unlike POSIX-compliant systems where fsync on a directory can flush directory entries to disk, Windows lacks a direct equivalent API for flushing directory-specific metadata or entry changes [1][2][3]. 3. Recommended Alternatives: Developers encountering this issue in cross-platform applications are generally advised to skip directory synchronization on Windows or to ensure individual files are handled correctly using FILE_FLAG_NO_BUFFERING and FILE_FLAG_WRITE_THROUGH when creating or opening them, rather than relying on flushing a directory handle [1][7][6]. 4. Volume-Level Flushing: For applications requiring true volume-wide synchronization, FlushFileBuffers can be used on a volume handle (e.g., \.\C:), but this requires administrative privileges [8][3].

site:learn.microsoft.com "FlushFileBuffers" "directory" handle
💡 Result:
The FlushFileBuffers function is designed to flush the internal buffers of a specified file, communication device, or pipe to the underlying storage or device [1][2]. Its primary purpose is to ensure that buffered data is written out to disk or the target destination. While you can obtain a handle to a directory by opening it with the FILE_FLAG_BACKUP_SEMANTICS flag [3], the FlushFileBuffers function is not intended for use with directory handles. When called on a handle, the function expects a file handle that supports write access (specifically requiring the GENERIC_WRITE access right) [1]. Using it with a handle to a directory typically does not provide the intended functionality of flushing file system metadata or directory contents to disk. For managing metadata or ensuring changes are committed to disk for directories and files, Windows generally relies on other mechanisms, such as: 1. System-level caching and write-through operations: Using flags like FILE_FLAG_WRITE_THROUGH when opening files can ensure that both data and metadata (such as timestamps or renames) are flushed to persistent media [4][5][6]. 2. File system operations: File system changes are managed by the operating system's cache manager and file system drivers (like NTFS), which handle the consistency of directory structures independently of FlushFileBuffers [4][2]. If you attempt to use FlushFileBuffers on a handle that is not a file, pipe, or communication device, the function will likely fail, returning zero, and you can retrieve the specific error code via GetLastError [1].

Do not call sync_all() on directory handles on Windows.
sync_all() maps to FlushFileBuffers, which requires GENERIC_WRITE, but Windows does not reliably support flushing directory handles. Adding .write(true) only passes the access check and does not make directory synchronization valid. Skip this operation on Windows or use a documented durability mechanism.

Scope the exemption to the main cache root.
keyhog_cache_contains_findings processes both cache roots, but this branch trusts any direct directory named execution-packs. A directory with that name under the matcher-artifacts root is not the signed execution-pack store and is skipped without inspection. Apply the exemption only to the main keyhog cache root, and add a regression test for the matcher-artifacts root.

…ches A --git-staged scan records staged paths matched by the repository's .keyhogignore under the Excluded counter, but both the gap reason and the summary warning claimed user removals are never counted there. That mislabeled a repo-policy skip as a default-policy skip (observed with staged CHANGELOG.md files in pre-commit hook scans). The texts now state the staged-scan attribution.
The outer container validation and extraction now share one spend rule (outer_entry_is_layer_payload): entries under blobs/ (OCI) or named layer.tar (legacy docker save) are exempt because they are re-read and accounted through their extracted inner entries; every other entry, including manifest.json, counts. Entry paths are normalized so a ./ prefix cannot dodge the match, and the validate-before-write guarantee again covers exactly the entries extraction charges.
FlushFileBuffers requires GENERIC_WRITE; FILE_FLAG_BACKUP_SEMANTICS alone lets the handle open but sync_all still fails with Access is denied. Observed on the windows-x86-64 action-e2e runner after the flag fix.
The job's e2e_all action-contract suite outgrew the 30-minute window after the consolidation restored its full test set; the runner cancelled the cargo test step at exactly 30 minutes with every completed test green.

Restrict outer budget exemptions to referenced layer payloads.
outer_entry_is_layer_payload exempts every blobs/... entry and every layer.tar path. The outer unpack still materializes these files, but unreferenced layers are not scanned and config or manifest blobs are read outside DockerUnpackBudget. A large unreferenced payload can therefore bypass the image-wide limit and exhaust disk space.
Build exemptions from manifest/index-listed layer paths. Charge all other outer entries. Add tests for non-layer OCI blobs and unreferenced layer.tar entries.

Resolution of the Devin findings:
|
The lane ran 60 minutes to the second and was cancelled mid-suite after the consolidation restored the full e2e_all set into it.
…adder Each test spawned calibrate-autoroute without the ci-lean fixture sentinels, so every one measured the full production ladder: minutes of CPU per test, eight tests in parallel, which saturated the runner and pushed the Integration (CLI) lane past both its old and raised time budgets. The sentinels select the bounded ladder; the contracts under test (staleness fail-closed and clean regeneration) do not depend on ladder depth.
The daemon isolation contract launched 24 clients although the production admission floor is eight, so low-core runners correctly refused excess scan work. The allocation test's process-global allocator also counted the sibling scaling test when libtest ran both in parallel. Keep the telemetry test within the guaranteed floor and serialize the two allocator measurements. Include the previously verified bounded Row 135 calibration change in the same test-surface chunk.
The e2e category manifest omitted scan_empty_dir_exit_zero. The daemon lifecycle suite also started three real daemons on automatic routing, which now correctly fails closed without calibration; parallel detector compiles then obscured that cause behind readiness timeouts. Wire the orphan, serialize daemon starts, and use the explicit CPU diagnostic route for lifecycle contracts that do not test autoroute.
The newly wired orphan expected an empty target to report clean exit 0, but current product truth rejects zero-byte coverage with exit 13. Rename the contract and assert both the exit and the corrective coverage message instead of weakening the fail-closed behavior.
Five Integration failures on run 32673390549 were stale expectations in newly wired orphan tests, not product defects: - config-path baseline pinned the removed top-level "confidence" field; the report schema carries evidence_score (renamed in the evidence-tier change), so the assertion now pins evidence_score 0.9. - full-prune exclude globs expected clean exit 0; zero-byte coverage is FAIL class, so they expect exit 13 with [] on stdout. - the high severity floor drops the low named finding but the generic entropy fallback resurfaces at review tier (non-blocking, exit 0). - staged-renames guard registers with --no-hook: the installed hook runs keyhog from PATH, absent on CI runners.
Nightly triage against run 32623829013: - reliability exit-contract: the AWS-key fixture lands at review tier under the documented evidence policy (exit 0 with review findings visible), so it can no longer stand in for a blocking finding. Swap to a checksum-confirmed PAT that blocks. - reliability determinism: normalize per-scan volatile fields (scan_id, generated_at/scan_started_at/scan_finished_at, created, duration_ms, written_at_ns) before byte comparison; use the real --create-baseline flag (--baseline compares and never writes) and enable --incremental so --incremental-cache persists the Merkle index. - fuzz scanner target: close the stride-sampled detector subset transitively over relation targets so the plan builder never sees a relation whose target is outside the compiled set (notion-integration-token -> notion-api-key split the sample). - GPU region-batch sharding gate: the CUDA budget assertion required an input-budget-capped result to equal a ceiling above that budget, which no input satisfies; assert both regimes explicitly. Verified locally: reliability_all 1235 passed (default features); gpu_region_batch sharding 13 passed with --features gpu.
The newly wired 'install, guard, and artifact identity' step ran for the first time on 787dc37 and timed the lane out: - four of the five tests run bare `keyhog install`, whose internal calibrate-autoroute measures the full production ladder; four parallel ladders stalled the step past its budget. The installs now carry the same ci-lean fixture sentinels as Row 135, selecting the bounded workload and deterministic timing evidence. - clean_cache_scan_fails_closed_without_installation asserted retired error wording; the uninstalled-scan failure is now the autoroute fail-closed contract (exit 2, names the missing calibrated decision, points installers at install.sh --calibrate / install.ps1 -Calibrate, and states no backend was substituted), so the test pins that. Verified locally under ci-lean: 5 passed in 272s.
…ontracts Product fixes: - Guard watcher reloads [scan].exclude when .keyhog.toml changes. The reload branch sat inside a filename check admitting only .keyhogignore and .gitignore, so config edits left the old matcher active. - Guard watching and keyhog watch no longer drop .cargo events. The directory skip policy listed .cargo in base while the scanner default excludes prune no such component; credentials.toml edits never reached the guard. Test contract updates (orphan suites, first-time execution): - Row 130: rustfmt-canonical assert collapse. - Row 140: relax daemon-active substring to match actual message format. - Row 141: pin scanner-truth parity for .cargo/credentials.toml; images are not watcher-level exclusions (extension denylist feeds the reader). - Row 144: calibrate cloned cache homes; missing-pack pins fail-closed exit 13; developer hatch uses explicit --backend cpu and pins current message format. - Row 145: hook run tests use --backend cpu (hook git-staged workload bucket differs from calibrate-autoroute core ladder); missing-pack pins exit 13 with NEVER SCANNED report. - Row 146: overflow on StalePolicy yields Ignore per product decision. - Row 158: calibrate fresh-state cache for filesystem scan routing. Data: - skip_dirs base=[] (empty); validate_optional_list permits it. - Unit test pins .cargo absence and empty-base loading.
