Fluxheim 1.8.2

Fluxheim 1.8.2 Release Notes

Fluxheim 1.8.2 completes unsigned Windows portable parity on native x86_64
MSVC while preserving the same seven public profiles used by Linux and Apple
Silicon macOS. Windows ARM64 is deferred until sustainable native build and
test infrastructure is available.

Windows Portable Release

• Build and execute unsigned .zip previews for full, wasm, cache,
  proxy, load-balancer, php, and config-tester with the native MSVC
  toolchain and deny Windows-target compiler warnings.
• Run the complete workspace suite plus live static, proxy, downstream and
  verified upstream TLS, memory and persistent storage-bin cache,
  load-balancer, integrity-authenticated snapshot create/list/rollback and
  doctor verification, admin, metrics, ACME storage, crash-restart recovery,
  CTRL_BREAK shutdown, and packaged-Wasm tests.
• Replace Unix-only filesystem, path, locking, shutdown, and
  certificate-storage assumptions with reviewed Windows-native behavior while
  retaining fail-closed owner, ACL, reparse-point, and exclusive-writer checks.
• Keep the Windows php profile on the shared FastCGI request path with
  external TCP pools. Managed PHP-FPM supervision remains Unix-only and is
  rejected during Windows configuration validation and runtime construction;
  a native Windows TCP FastCGI responder regression proves the supported path.
• Enforce confidential Windows ACLs for TLS, ACME, admin, metrics, snapshot,
  cache-encryption, peer-fill, and discovery credentials; new private files and
  directories receive protected DACLs before secret bytes are written.
• Open Windows static response files through retained directory handles with
  reparse traversal disabled, and reject untrusted writable cache, state,
  logging, configuration, ACME, and PHP-spool ancestors.
• Preserve Windows cache purge/refresh semantics with delete-sharing, bound
  cache reads across concurrent growth, make snapshot/ACME/cache directory
  flushes real, and use delete-on-close request-body spool files.
• Pin and record the manual review evidence for the exact
  windows-permissions dependency checksum and isolate first-party unsafe
  Windows path traversal in the narrowly scoped
  fluxheim-windows-security crate.
• Evaluate Windows trust policy against retained target and ancestor handles,
  and create cache object and encryption-state temporary files relative to a
  validated parent before writing bytes.
• Make dedicated builder SSH provisioning global and account-scoped even when
  the vendor configuration ends in a Match block, and reject non-SSH, mixed,
  or duplicate tag signature formats before allowed-signers verification.
• Bootstrap disposable Windows Server 2025 Desktop Experience builders from a
  trusted Linux release host, install the required native toolchain, transition
  to a dedicated non-administrator SSH account, and verify Administrator SSH
  is no longer accepted. Fresh-host provisioning handles empty OpenSSH groups,
  refreshes newly installed prerequisite paths without exposing mutable Rust
  tools machine-wide, and validates the global policy around the stock
  administrator Match block.
• Run the verified-upstream-TLS smoke against a second native Fluxheim/Rustls
  process so it remains reliable under public-key-only OpenSSH sessions without
  granting access to the machine-wide Windows private-key store.
• Flush the load-balancer state file and containing directory after atomic
  replacement on Windows.
• Roll back newly created Windows files after a retained-parent ACL rejection
  through delete-capable handles, and surface any rollback failure explicitly.
• Bind the Windows filesystem-security audit to the complete reviewed
  first-party source boundary as well as the pinned ACL dependency checksum.
• Make the focused Wolfi, Alpine, Debian, and SUSE BCI PHP images
  self-contained managed
  PHP-FPM runtimes with one smoke-verified application extension contract,
  including MySQLi and its required MySQLnd module. The PHP image smoke rejects
  extension load warnings and executes a real request through each image.
• Replace php-suse-micro with php-suse-bci. The dedicated SUSE BCI PHP base
  provides an official PHP repository and matching PHP-FPM stack, while the
  pinned SL Micro base does not. Other SUSE Micro profiles remain supported,
  and Windows PHP continues to use external TCP FastCGI as documented.
• Replace the yanked transitive wnaf 0.14.0 dependency with 0.14.1.
• Add an opt-in off-host Windows ingress smoke that runs the packaged php
  profile against a checksum-pinned official PHP NTS FastCGI process and
  verifies real PHP output, request-body forwarding, and CGI TLS context over
  public HTTP and certificate-validated HTTPS.
• Normalize canonical Win32 verbatim roots to ordinary DOS or UNC paths before
  sending SCRIPT_FILENAME, DOCUMENT_ROOT, or PATH_TRANSLATED to an
  external Windows FastCGI process. This fixes real php-cgi.exe requests that
  previously returned No input file specified.
• Add a separate opt-in Windows ACME lifecycle smoke that performs an isolated
  Let's Encrypt staging HTTP-01 issuance, activates the installed certificate,
  and verifies its hostname and fingerprint from an off-host client.
• Add an opt-in off-host packaged-profile matrix that verifies public HTTP and
  certificate-validated HTTPS through the Windows proxy, load-balancer,
  cache, and full ZIPs. It proves two-origin selection and failover, memory
  cache reuse, and persistent storage-bin recovery with the origin offline.
• Refresh the pinned Rust toolchain and container builders to 1.98.1, update
  compatible workspace dependencies, and move sanitization, base64-ng,
  Brotli, Zstandard, MaxMindDB, AWS-LC, Rustls, Wasmtime, and the QEMU setup
  action to their current reviewed releases.
• Keep the dedicated Windows build account's mutable Rust toolchain out of the
  machine-wide executable search path, clean obsolete machine environment
  entries, and make the release runner fail closed when invoked with an
  administrator token.
• Move the Windows release compiler into an Administrator-provisioned,
  recursively read-only tree with a verified file inventory. Official evidence
  requires a builder provisioned within 24 hours, a fresh per-run Cargo home,
  allowlisted build environment, and protected Cargo working directory.
• Authenticate admin HTTP requests before they can trigger or observe an
  expired self-healing rollback.
• Return failed expired-validation rollbacks directly to authenticated admin
  clients so confirmation and successful health reports cannot overwrite the
  preserved retryable recovery state.
• Create private Windows directories relative to a retained parent handle and
  apply their protected ACL atomically, preventing junction replacement between
  validation and creation.
• Validate fresh builders against the standard Windows volume-root ACL without
  weakening replacement, ownership, or ACL protections; remove unused Rustup
  proxy links before sealing future toolchain inventories and correctly record
  the native compiler host without colliding with PowerShell's reserved
  $Host variable.
• Stage privileged bootstrap scripts only in a newly created directory inside
  the protected Administrator profile. Provisioning rejects any pre-existing
  object instead of attempting to repair its ACL. Official evidence remains
  limited to fresh, single-tenant disposable hosts.
• Align Windows release production with Linux ARM and macOS: reproduce the
  default release binary in two clean target directories, build each of the
  seven profile archives once, and aggregate native test evidence and checksums
  through the repository-owned Linux helper.
• Build Windows MSVC executables with deterministic PE timestamps and CodeView
  identifiers, proving byte-identical default binaries across clean target
  directories on the native release host.
• Derive Unix O_NOFOLLOW from each target ABI instead of using an x86 Linux
  literal, restoring symlink rejection on Linux ARM for configuration, ACME,
  Wasm, GeoIP, observability CA, upstream TLS, and static-file inputs.
• Run the complete Linux x86_64 and aarch64 archive matrices, the native
  Windows runtime and seven-ZIP matrix, and the Apple Silicon seven-profile
  archive validation before release preparation.

Exact-Tag Publication Gate

• Produce exact-tag architecture, checksum, test, and reproducibility evidence
  from a dedicated native x86_64 Windows builder. Evidence records the
  Windows edition and build, and every executable in all seven ZIP profiles
  must launch and report the expected version. Planning-only output and the
  normal x86_64 CI result are not substitutes for exact-tag release evidence.
• Verify the default release binary is reproducible across two clean target
  directories, collect the seven checked ZIP profiles, and destroy the
  disposable builder.

The Unix/OpenSSL FIPS support shim remains excluded as an independent Windows
workspace package while staying covered by the dedicated Linux OpenSSL-FIPS
profiles.

These archives remain unsigned previews. Authenticode and installer work stays
deferred until company-backed publisher credentials are available.
