- gate.php : ETag now derived from size+mtime instead of md5_file($zip).
Previously the gate hashed the entire 14 GB ZIP on every HEAD/GET call
(including each of 8 parallel segments) → 30s-5min preparation lag for
clients before the first byte. Now <1ms per request.
- SignManifest : disk-backed cache for SHA-256 keyed by (path,size,mtime).
Re-signing 5×14 GB versions used to take ~25 min, now ~1s when nothing
changed. New "Force re-hash" toggle in admin to ignore the cache.
- versions.php : per-row "🔁 Hash" button to sign a single version, plus
a "⚙ Hash" dropdown to toggle hashAlgorithm:none for builds where the
user accepts skipping client-side verification (manifest stays signed
Ed25519, only the per-ZIP SHA-256 verification is bypassed).
- DownloadUrl.php : signed-URL TTL bumped 1h → 6h to cover slow ADSL users
who need >1h to finish a 14 GB download.
- .gitignore : track server/builds/.htaccess + gate.php (still ignore the
actual ZIP/exe binaries).

OVH mutualisé serves PHP via FastCGI which strips the Authorization
header by default for security. The user's curl test of GET
/api/download-url/{ver} returned 401 even with -H "Authorization:
Bearer <key>" because $_SERVER['HTTP_AUTHORIZATION'] was empty server-side.
Fix on two layers:
1. .htaccess at root re-injects the header into the Apache env so PHP
can read it via the standard $_SERVER variable. The mod_rewrite
one-liner `RewriteRule ^ - [E=HTTP_AUTHORIZATION:%1]` is the de-
facto FastCGI workaround.
2. DownloadUrl.php now reads from any of: $_SERVER['HTTP_AUTHORIZATION'],
$_SERVER['REDIRECT_HTTP_AUTHORIZATION'] (passthrough variant),
apache_request_headers(), getallheaders(). Belt and braces — works
regardless of host config. Falls back to ?key= as before.

Three deliverables shipped together so the next deployment cycle has a
clean distribution story.
(1) Auto-update of the launcher itself
---------------------------------------
- Models: RemoteManifest gains an optional `launcher` section
(LauncherInfo: version, minRequired, download {url,size,sha256},
releaseNotesUrl). Server-side, sign-manifest.php passes it through
unchanged; admins edit versions.json with the new launcher entry +
upload PSLauncher-X.Y.Z.exe to /builds/launcher/.
- Core: ILauncherSelfUpdater compares assembly version against
manifest.launcher.version using the existing SemVer parser, and
reuses DownloadManager (Range/resume/sha256 already proven on the
game ZIPs) to download the new exe into
%LocalAppData%/PSLauncher/selfupdate/.
- New project PSLauncher.Updater (~34 MB self-contained console exe):
spawned by the main app with --target / --source / --pid / --launch.
Waits for the main process to exit (or for the file lock to release),
backs up the current exe to .bak, copies the new file in place, and
restarts. .bak survives the swap so the user can roll back manually.
- App.csproj now declares Version=0.5.0 — currently shipped baseline.
PSLauncher.App.csproj sets a fixed AssemblyVersion so reflection-based
comparison works deterministically.
- MainViewModel.PromptLauncherUpdate: dialog after CheckForUpdates if
the manifest advertises a newer launcher. Download with progress in
the existing footer, then Application.Shutdown() so the Updater can
do its job.
(2) Inno Setup installer
------------------------
installer/PSLauncher.iss + build-installer.ps1 produce a single
PSLauncher-Setup-X.Y.Z.exe (~80 MB) that installs into
Program Files\ASTERION VR\PSLauncher\, drops both PSLauncher.exe and
PSLauncher.Updater.exe side by side (the updater MUST live next to
the target), creates Start Menu + optional Desktop shortcuts, and
registers a clean uninstall entry. The user's %LocalAppData%
(license, logs, cache) is intentionally untouched on uninstall — same
license survives a reinstall.
build-installer.ps1 chains dotnet publish for both projects and ISCC
in one command. README explains the bump-version workflow.
(3) HMAC-signed download URLs
-----------------------------
- New PHP route GET /api/download-url/{version} (Authorization: Bearer
<licenseKey> or ?key=...). Validates the license, checks
download_entitlement_until >= minLicenseDate of the version, and
returns a HMAC-signed URL (path|exp|licId, hash_hmac SHA-256, valid
1 h) + sha256 + sizeBytes for verification.
- /builds/.htaccess routes every *.zip request to gate.php. gate.php
validates exp, lic, sig (constant-time hash_equals), then streams
the file with Range: support so the launcher's resume keeps working.
Audit log gets a download_url_issued entry per request.
- Client-side wired transparently: LicenseService gains
GetSignedDownloadUrlAsync(version) that GETs the endpoint with the
decrypted license key from DPAPI. MainViewModel calls it before
every download; if the endpoint returns 404/401/network-error, the
client falls back to the manifest's plain download.url (graceful
degradation for setups that haven't deployed gate.php yet).
Note on PHP streaming for 14 GB ZIPs: gate.php uses set_time_limit(0)
+ ignore_user_abort(true) + 1 MiB chunked fread with periodic flush.
Works on OVH mutualisé but holds a PHP-FPM slot for the duration. If
parallel downloads scale past a few clients, switch to
mod_xsendfile or migrate /builds/ to Cloudflare R2 with native
S3-presigned URLs and remove the gate entirely.
