WARNING: Unguarded receipt-field access can abort a launch that the documented invariant says must never block on receipts.
The JSON parse immediately above is wrapped defensively, but CompareExecutable(receipt.Executable, report) and the foreach (... in receipt.ArchiveRoots) below it are not. A corrupt or tampered receipt that still parses successfully — e.g. "Executable": null, "ArchiveRoots": null, or a null archive-root entry — produces an unhandled NullReferenceException here; an uncaught SecurityException or transient IO error from FileInfo inside CompareExecutable has the same effect. RevalidateAsync is awaited on the launch path (RevalidateLaunchReceiptAsync -> LaunchProfileAsync), so the exception propagates and fails the launch, contradicting the stated guarantee that receipt and drift issues never block a launch. Wrap this block in the same try/catch used for the parse, or null-guard the receipt fields before use.

WARNING: Null EnvironmentVariableHashes dereference can still abort the launch.
This foreach dereferences receipt.EnvironmentVariableHashes with no null guard. A receipt that parses but deserializes with "EnvironmentVariableHashes": null (a tampered or corrupt file) reaches CompareEnvironment through CompareUpcomingLaunch on the launch path, where the iteration throws NullReferenceException; LaunchProfileAsync's catch-all then turns that into a launch failure. That is the same corrupt-receipt outcome the new RevalidateAsync guard (lines 136-159) and the RevalidateAsync_WithNullReceiptFields_ReportsDriftWithoutThrowing test were added to prevent, so the tolerance added on the read path is not extended to the comparison path and a null-field receipt still blocks a launch.

SUGGESTION: A null recorded Executable silently skips executable drift rather than reporting it.
When receipt.Executable is null (a corrupt or tampered receipt that deserializes with "Executable": null) but upcoming.ExecutablePath is set, this if is false and no drift line is added. The sibling CompareArchiveRootConfiguration handles the analogous case by reporting "newly configured" when the recorded root is null but an upcoming root exists (lines 308-312). Note that the surrounding try/catch would otherwise have turned a null dereference into a generic "Receipt could not be compared" drift line, so this guard actually leaves the executable field as the one comparison that reports nothing for a null recorded value. For consistency, consider reporting the executable as newly/differently configured here too (e.g. Executable path changed from (none) to {upcoming.ExecutablePath}).

[WARNING]: Schema version is written but never checked on read
LaunchReceipt.SchemaVersion is stamped on record (default LaunchReceiptConstants.CurrentSchemaVersion = 2) but RevalidateAsync never inspects it after deserializing. The schema has already moved once (v1 receipts carried EnvironmentVariableHashes, which no longer binds), and a future field rename turns old receipts into a mostly-empty model with HasReceipt = true and zero drift lines - silently reporting no drift for a receipt the code cannot actually interpret. A cheap version check that adds a drift line (or rewrites the receipt) would make version skew visible instead of invisible.

[WARNING]: Test never asserts the drift it exists to guarantee
CompareUpcomingLaunch always returns a non-null report, so Assert.NotNull(report) can never fail. The fixture deliberately carries null Executable and null ArchiveRoots, and the service contract says malformed fields must degrade to a drift line, never to an exception - this test only pins the never-throws half. A regression that silently reports no drift for null fields would keep it green. Assert report.HasDrift (and ideally a specific field, e.g. the executable-path drift line).

[WARNING]: CancellationToken.None contract of RecordLaunchAsync is not pinned
GameLauncher.RecordLaunchReceiptAsync deliberately passes CancellationToken.None (remarks at GameLauncher.cs:1730-1736: forwarding the launch token would abandon a half-done receipt write after the child process spawned, or surface an OCE that reports a running game as a failed launch). This verify accepts It.IsAny<CancellationToken>(), so a regression that forwards the caller's token - exactly the bug the remarks warn about - would pass. Assert It.Is<CancellationToken>(t => t == CancellationToken.None) (the RevalidateAsync verify legitimately keeps It.IsAny, since production forwards the caller's token there).

[WARNING]: Receipt path unconstrained; the feature can die silently with all tests green
Production revalidates at Path.Combine(dynamicWorkspacePath, profile.Id) (GameLauncher.cs:844) but records to workspaceInfo.WorkspacePath - the two coincide only because every workspace strategy builds its path as Path.Combine(WorkspaceRootPath, Id) with Id = profile.Id. Since this test (and the E2E test) mock ILaunchReceiptService, nothing verifies the receipt is read from the directory it was written to. If a strategy ever derives the folder differently, revalidation reports no receipt - success by design - and drift detection is permanently dead with zero failing tests. Assert the expected path in the matcher, e.g. It.Is<string>(p => p == Path.Combine(workspacePath, profile.Id)).

[SUGGESTION]: Magic strings in a PR that adds a constants class
receiptPath + ".tmp" hardcodes the temp suffix, and NameOrNone (lines 234-235) hardcodes the display placeholder "(none)", while this same PR adds LaunchReceiptConstants and FileTypes.LaunchReceiptFileName for exactly this purpose (precedent: CsvConstants.TemporaryCacheFileExtension = ".tmp"). Centralizing both avoids literal drift. Additionally, a failed write or File.Move leaves an orphaned launch-receipt.json.tmp in the workspace (no cleanup path), and the deterministic temp name means two concurrent recordings for the same workspace would scribble on the same .tmp - latent today because the launcher serializes per profile, but a try/finally delete or unique suffix would close both holes.

[SUGGESTION]: Loose substring assertion for the success path
Assert.Contains("launched successfully", vm.StatusMessage) (same at line 738) passes even if process-ID reporting or profile-name resolution in the status line regressed. The notification verifications are precise; consider asserting the full {name} launched successfully (Process ID: 123) shape for symmetry.

[SUGGESTION]: Setup calls never assert that recording succeeded
Roughly twenty tests use RecordLaunchAsync as unasserted setup (80-81, 109, 125, 144, 162, 182, 204, 221, 238, 297, 314, 331, 347, 363, 381, 406, 429, 448, 504, 530, 547), unlike the repo convention in GameLauncherTests (Assert.True(result.Success, result.FirstError)). If recording silently regressed, these tests would fail with confusing secondary effects (missing receipt file, HasReceipt == false) instead of a clear message. One assert per setup call - or a shared record-and-assert helper - keeps CI failures self-explanatory.

[SUGGESTION]: The drops-legacy-fingerprints assertions are trivially true
The model has no EnvironmentHashSalt/EnvironmentVariableHashes members, so System.Text.Json skips them at deserialize and the re-serialized receipt can never contain legacy-key/legacy-digest - lines 464-465 pass regardless of any service behavior. Only the rewrite assertions (466-470) do real work. Worth a comment clarifying that the guard is schema-level (against re-introducing the properties), so nobody mistakes these lines for service-logic coverage.

[SUGGESTION]: Failure-path test never verifies recording was attempted
Assert.True(result.Success) proves the flow reached the final return, not that RecordLaunchAsync was actually called on this path. A regression that skips receipt recording when revalidation reported drift would keep this test green (the happy-path test only covers a drift-free launch). Add a Times.Once verification for RecordLaunchAsync so the test name matches what is enforced.

[SUGGESTION]: New registration unasserted by the module's own DI test
GameProfileModuleTests.AddLaunchingServices_ShouldRegisterAllExpectedServices (line 71) still asserts only ILaunchRegistry and does not cover ILaunchReceiptService. Asserting it would also catch missing transitive dependencies - LaunchReceiptService needs IFileHashProvider, which production supplies via ContentPipelineModule - before runtime resolution fails.

The repo's enforced naming rule (.editorconfig async_methods_must_end_with_async, AGENTS.md CS-R1005) requires every Task-returning method to end with Async. All pre-existing async tests in this file follow it, and the sibling new test at line 1372 does too — but this one and LaunchProfileAsync_WithPreviousReceipt_ComparesUpcomingConfiguration (1426), LaunchProfileAsync_WhenReceiptRecordingFails_StillSucceeds (1482) and LaunchProfileAsync_WhenReceiptRecordingThrows_StillSucceeds (1526) don't, so DeepSource CS-R1005 will flag the new lines.

The ViewModels tests in this same PR extracted exactly this shape into CreateProfileItem/CreateLauncherViewModel, and LaunchReceiptServiceTests reuses CreateContext/RecordSuccessfullyAsync; a shared private helper returning (workspaceInfo, processInfo) would remove ~70 lines and reduce SonarCloud new-code duplication.

[WARNING]: New user-facing drift line is hardcoded English
"Previous launch receipt could not be revalidated" flows into GameLaunchInfo.ReceiptDriftWarnings and is rendered verbatim inside the drift toast by GameProfileLauncherViewModel.BuildReceiptDriftNotice, so Arabic/Russian users get an English sentence inside an otherwise localized notification. This same commit localized the toast's wrapper strings (GameProfiles.Notification.LaunchChanged.Title/Message/More with 1:1 ar/ru parity) but not this new body line. The sibling DriftedFields strings share the gap as a pre-existing pattern, but this one is introduced here; a resx key resolved at the ViewModel boundary (the service has no ILocalizationService) would close it, with the literal assertion at GameLauncherTests.cs:1417 moving alongside.

[SUGGESTION]: Drift message renders raw booleans and mislabels a manifest-shape change as a "selection" change
HasVariants records whether the game-client manifest declares variants at all (set from gameClientManifest.Variants.Count > 0 in GameLauncher.ResolveVariantIdentity), not which variant was selected — the selection is already covered by the VariantRuntimeIdentifiers comparison below. When a manifest update adds or drops its variants block the user now gets two toast lines for one underlying change, and this one reads "Manifest variant selection changed from True to False" in the drift notification — capitalized CLR booleans are developer rendering, not user text, and nothing was actually "selected". Consider a state description (e.g. "Game client manifest now declares platform variants" / "no longer declares platform variants") or folding the signal into the identifiers check.

[SUGGESTION]: Windows: a profile-set CNC_* override is now invisible to every drift check
On Windows this method starts from an empty dictionary, so a profile's CNC_GENERALS_INSTALLPATH/CNC_ZH_INSTALLPATH override lands only in EnvironmentVariables (the child env) and never in ArchiveRoots; CompareEnvironment then excludes those names via IsArchiveRootVariable while CompareArchiveRootConfiguration compares installation-derived roots. Changing such an override on Windows therefore produces no drift line at all — the previous env-based comparison flagged it. Since Windows engines read the registry the silence is arguably correct, but it is the one profile-edit category that went from reported to fully silent, and LaunchReceipt.ArchiveRoots' doc ("keyed by the environment variable that carried each root") no longer describes Windows records. Worth a comment stating the intent, or filtering IsArchiveRootVariable only when the name is present in ArchiveRoots.

[SUGGESTION]: null! for the settings ViewModel deviates from this file's existing factories
Both pre-existing factories (CreateViewModelWithMockDependencies, CreateViewModelWithLauncherFacade) construct a real GameProfileSettingsViewModel for this parameter; this new helper passes null!. It is unreachable on the launch paths these tests exercise, but a future test reusing the helper for the edit/create flows that do use the settings ViewModel would fail with a confusing NRE. Wiring the same construction the neighboring factories use keeps the helpers consistent.

[SUGGESTION]: Re-record assertion is a one-bit check
After clearing the environment and recording again, Assert.NotEmpty(...ArchiveRoots) would still pass if the second recording wrote the wrong root under the wrong key. The first half of the test pins the discriminating behavior precisely (recorded path equals context.ArchiveRoots[CNC_ZH_INSTALLPATH], not the env-carried ignored path); re-asserting receipt.ArchiveRoots[RetailArchiveConstants.ZeroHourInstallPathVariable].Path equals the fixture root — and/or that the ignored env path is absent — makes the re-record half do real work too.

[SUGGESTION]: Russian "...and {0} more" is missing its noun
"...и ещё {0};" reads as "…and 3 more;" with no object — every comparable Russian count string in this file names the noun (e.g. "{0} элементов", "{0} файл(ов)…"). A phrasing like "...и другие изменения ({0}); полные сведения см. в журнале." stays grammatical for any count, since Russian numeral agreement makes a bare "{0} изменений" wrong for 1 and 2; alternatively add the noun with the same hedge style used elsewhere in the file.

[SUGGESTION]: Doc claim doesn't match workspace preparation for non-GameClient manifests
"that is the legacy fallback, which resolves the executable by filename search with no variant machinery involved" — WorkspaceStrategyBase.ResolveWorkspaceExecutablePath (lines 610-620) still runs ManifestVariantResolver.ResolveEntryPoint on an Executable/entry-point-bearing manifest when no GameClient manifest exists, so variant machinery does participate in exactly this case; the receipt just records Variant = null for it. Either extend ResolveVariantIdentity to capture that resolution as well, or soften the claim, so future readers don't trust "no variant machinery involved" when reasoning about entry-point drift.

SUGGESTION: Hand-maintained key allowlist couples this notice builder to every future localized drift entry
ReceiptDriftWarnings now mixes English prose entries from LaunchReceiptService's drift comparisons with resx keys, and this is pattern must enumerate every localizable key by hand. The service can emit new drift entries at any time; the next one added as a key but omitted from this pattern will render its raw identifier (e.g. GameProfiles.Notification.LaunchChanged.NewKey) verbatim in the user's notification. localization.TryGetString(warning, out var localized) ? localized : warning resolves keys and passes prose through unchanged, with no allowlist to keep in sync — and would remove this ~190-character line. Related: LaunchReceiptConstants documents itself as serialization constants but now hosts display-localization keys.

Summary
Record what each successful launch consisted of and cheaply compare subsequent launches against that receipt so configuration and filesystem drift is visible.

Testing
dotnet test GenHub/GenHub.sln -c Release— 1,476 tests passed.Risks and rollback
Routine revalidation deliberately avoids content hashing, so a same-size replacement with a deliberately preserved timestamp is not detected. Receipt persistence is best-effort and does not fail an otherwise successful launch. Reverting this PR removes receipt recording and drift notifications.

Greptile Summary
This PR adds versioned launch receipts and drift reporting.
Confidence Score: 4/5
This PR should not merge until launch receipts stop exposing an offline verification oracle for profile environment secrets.
Profile-defined environment values are transformed into HMACs, but the receipt serializes the HMAC key alongside those hashes, allowing anyone who obtains the file to test likely values and recover low-entropy credentials.
Files Needing Attention: GenHub/GenHub/Features/Launching/LaunchReceiptService.cs; GenHub/GenHub.Core/Models/Launching/LaunchReceipt.cs
Security Review
The revised environment hashing still permits offline recovery of low-entropy secrets because each receipt stores both the keyed hashes and the key required to verify guesses.
