`33445470664` concluded `cancelled` at `2026-08-31T23:11:19Z`, with 13
successful jobs, one failed macOS job, and one cancelled Windows job. The macOS
runner filesystem rejected creation of the
raw-C1 filename fixture with `EILSEQ`. The hosted Windows job stalled in `make
check`; a MinGW/Wine reproduction isolated the cause to
`test --password-prompt ... </dev/null` entering `_getch`, and the remaining
native job was cancelled.
The 5.2.8 fixture treats that creation refusal as an explicit `SKIP`; on a
filesystem that accepts the byte, the scanner must still reject the compiled
magic and render the path without emitting the raw C1 byte. No result from the
immutable tag transfers automatically to 5.2.8. The Windows prompt correction
rejects a redirected/non-console standard input before entering `_getch` and
adds a native EOF regression; it also requires fresh exact-candidate evidence.
## 5.2.8 CodeQL High path-race corrections
CodeQL High #5 identified SDK key-copy publication that reopened the output
path and then applied `chmod` to that mutable name. The copy now uses the core
atomic publisher, sets POSIX mode on the open temporary descriptor, checks
read/close/publication failures, and replaces only the destination directory
entry. `sdk-test` covers symlink and hardlink sentinels and expected key modes.
CodeQL High #6 identified the POSIX disk-restore `lstat`-then-`open` sequence.
Restore now opens once with `O_NOFOLLOW` and without truncation, classifies that
descriptor with `fstat`, and retains the same raw-device descriptor through
capacity checks and writes. Regular-file destinations retain the existing
atomic publisher.
CodeQL High #7 identified benchmark cleanup's `lstat`-then-recursive-path
sequence. POSIX cleanup now pins each component with `openat` and removes leaves
with `unlinkat`; Windows pins ancestors/children, opens reparse points without
following them, recurses only into a plain directory held against rename, and
after emptying a directory reopens it relative to the pinned parent, verifies
its volume and file index against the traversal handle, and marks only that
identity-checked handle for deletion. The live-workspace
regression injects a directory symlink and verifies that its external sentinel
survives. These are reviewed fixes and regression coverage,
not independent certification or proof that a 5.2.8 hosted gate passed.
The exact 5.2.8 candidate must repeat the required suite. Native Windows and

# ZUPT Changelog # ZUPT Changelog
## [5.2.8] — 2026-08-31 — Path-race hardening and native-fixture correction
Corrective successor to the immutable, unpromoted `v5.2.7` candidate.
Exact-tag GitHub Actions run `33445470664` reached a macOS failure because the
runner filesystem rejected creation of the raw-C1 filename fixture with
`EILSEQ`. The workflow concluded `cancelled` at `2026-08-31T23:11:19Z`, with
13 successful jobs, one failed macOS job, and one cancelled Windows job.
The hosted Windows job stalled in `make check`; a MinGW/Wine reproduction
isolated the cause to `test --password-prompt ... </dev/null` entering
`_getch` despite redirected standard input. The tag and its evidence remain
unchanged.
- Close CodeQL High #5 in SDK key saving by copying into the core atomic
publisher's already-open private object, applying POSIX key permissions with
`fchmod` on that descriptor, checking read/close/publication failures, and
replacing only the requested directory entry. Symlink and hardlink target
sentinels and private/public key modes are covered by the SDK regression.
- Close CodeQL High #6 in POSIX disk restore by opening the target once without
truncation or final-symlink following, classifying that descriptor with
`fstat`, and retaining the same device descriptor through capacity checks and
writes. Regular-file restores continue to use atomic publication.
- Close CodeQL High #7 in benchmark cleanup by resolving POSIX components with
`openat(..., O_NOFOLLOW)`, deleting relative to pinned descriptors with
`unlinkat`, and using pinned, reparse-point-aware handles for Windows
traversal. The regression injects a directory symlink into a live workspace
and verifies that cleanup does not visit its target.
- Treat inability to create the raw-C1 scanner filename as an explicit fixture
skip on filesystems that reject the byte; when creation succeeds, the unsafe
diagnostic-escaping assertions still run unchanged.
- Reject redirected or otherwise non-console Windows password prompts before
entering `_getch`, handle console EOF as an error, and cover the native
redirected-input path so it cannot hang a release gate.
- Run `sdk-test` from both `release-check` and the hosted GCC/Clang Linux job so
the atomic key-save regression cannot silently fall outside release gates.
- Carry the v5.2.7 archive format, cryptography, bundled codec release, and SDK
ABI forward unchanged. These are implementation and test-integration
corrections, not a wire-format or API change.
- Realign current code, package, workflow, artifact, and documentation
references to 5.2.8. AUR/Homebrew SHA-256 and Guix content pins remain
pending until the final reproducible archive is generated.
- Require fresh exact-`v5.2.8` source, checksum, hosted CI, native-platform,
package, OBS, and promotion evidence. This entry does not claim those gates
passed, and no v5.2.7 result transfers automatically.

rejected creation of the raw-C1 scanner fixture
with `EILSEQ`; the hosted Windows job stalled in `make check`, and a MinGW/Wine
reproduction isolated the cause to a redirected password prompt entering
`_getch`. Version 5.2.8 makes those test

* Close CodeQL High path-race findings in SDK key publication,
descriptor-first disk restore, and benchmark workspace cleanup.
* Make the raw-C1 scanner fixture explicitly skip filesystems that reject
the byte with EILSEQ, reject redirected Windows prompts before _getch, and
add sdk-test to release/hosted Linux gates.
* Preserve immutable, unpromoted v5.2.7 run 33445470664: 13 jobs succeeded,
