Summary

Introduces the Replay Manager CRC mapping infrastructure and binary .rep header parser to resolve gameclient compatibility for replays. Replays embed exeCRC and iniCRC values which are matched against a centrally maintained GitHub Gist catalog of gameclient releases.

Closes #295

Motivation

Replays in C&C Generals and Zero Hour require matching gameclient versions and data files. Because versionString (e.g. "1.04") is hardcoded across third-party builds, the executable CRC (exeCRC) and configuration CRC (iniCRC) stored in the replay header serve as the authoritative version identifiers.

Changes

  • Core Models & Enums:
    • Added ReplayCompatibilityStatus enum (Compatible, Downloadable, Orphaned, Unknown).
    • Added CrcMappingEntry and CrcCatalog domain models.
    • Extended ReplayMetadata with CRC fields, formatted hex strings, and build timestamp strings.
    • Extended ReplayFile with CompatibilityStatus and MatchedClient.
    • Added centralized constants in ReplayManagerConstants for Gist URL, header magic (GENREP), cache keys, and offline persistence.
  • Interfaces & Services:
    • Implemented IReplayHeaderParser and ReplayHeaderParser for binary .rep files.
    • Implemented ICrcMappingRegistry and CrcMappingRegistry with thread-safe normalized lookups.
    • Implemented CrcCatalogUpdateService inheriting ContentUpdateServiceBase for 24h Gist polling, in-memory caching via IDynamicContentCache, and local fallback snapshots.
    • Integrated header parsing and compatibility resolution into ReplayDirectoryService.
    • Wired services and typed HTTP clients in ReplayManagerModule.
  • GameClient CRC Catalog (GitHub Gist):
  • Unit Tests:
    • Added ReplayHeaderParserTests, CrcMappingRegistryTests, and CrcCatalogUpdateServiceTests.

Verification

  • All 2,205 unit tests in GenHub.Tests.Core passing cleanly with zero warnings.
  • Solution builds with zero compiler/StyleCop warnings.
  • Verified binary header parsing and CRC resolution against SAGE engine specification.

High-Level Assessment

The following are alternative approaches to this PR:

1. Unified gameclient identity registry
  • ➕ Combines CRC, SHA-256, manifest, and installed-client state in one source of truth.
  • ➕ Avoids parallel replay-specific and gameclient hash registries as compatibility expands.
  • ➖ Requires broader changes to existing gameclient detection and installation services.
  • ➖ Couples initial replay parsing delivery to a larger identity-model migration.
2. Bundle a versioned catalog
  • ➕ Provides deterministic mappings without network or Gist availability concerns.
  • ➕ Allows catalog changes to follow normal repository review and release controls.
  • ➖ New client mappings require an application release.
  • ➖ Cannot respond quickly to third-party client builds.

Recommendation: The separate parser, registry, and refresh service is appropriate for an isolated first delivery and supports rapid catalog updates with offline resilience. As compatibility matures, route status resolution through an installation-aware gameclient identity service rather than treating CDN availability as an installed-client signal.

Grey Divider


Action required

1. Mismatched INI CRC accepted ✓ Resolved 🐞 Bug ≡ Correctness
Description
TryGetEntry falls back to an executable-only match whenever the exact CRC pair is absent, so a
replay with the same executable CRC but an unknown or different INI CRC is assigned a known client.
This defeats the pair lookup contract and can label incompatible data files as compatible or
downloadable.
Code

GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcMappingRegistry.cs[R30-34]

+        // Fallback: match by exeCRC alone if exact pair not found
+        if (TryGetEntryByExeCrc(exeCrc, out var exeFound))
+        {
+            entry = exeFound;
+            return true;
Relevance

●●● Strong

The implementation contradicts the pair-lookup contract; recent accepted findings favor correcting
compatibility identity mismatches.

PR-#419

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The interface describes TryGetEntry as lookup for the executable and INI CRC pair, and the
registry first checks that pair but then returns an executable-only entry on any miss. The directory
resolver treats that fallback as a successful compatibility match.

## Issue description
Pair lookup accepts an executable-only fallback even when the supplied INI CRC does not match the catalog entry.

## Issue Context
Replay compatibility depends on both executable and configuration CRCs. Keep executable-only lookup available through its dedicated API, but do not use it to satisfy `TryGetEntry(exeCrc, iniCrc, ...)`.

2. Short stream reads reject replays ✓ Resolved 🐞 Bug ≡ Correctness
Description
ParseHeaderAsync(Stream) performs a single ReadAsync and treats that count as the complete
header. Streams may legally return fewer requested bytes while more data remains, causing valid
replays to fail truncation checks or lose later metadata.
Code

GenHub/GenHub/Features/Tools/ReplayManager/Services/ReplayHeaderParser.cs[R57-58]

+            var buffer = new byte[16384];
+            var bytesRead = await stream.ReadAsync(buffer.AsMemory(0, buffer.Length), cancellationToken);
Relevance

●●● Strong

Single-read parsing is a deterministic stream correctness bug; recent parser/import feedback
supports robust handling of partial operations.

PR-#385

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
Only one read populates the buffer, and its returned count controls the initial size check, every
fixed-field check, and all null-terminated string scans. The file overload delegates directly to
this implementation.

3. Catalog startup marks replays orphaned 🐞 Bug ≡ Correctness
Description
ResolveCompatibility marks every unmatched CRC as Orphaned, but the hosted catalog service
intentionally waits 30 seconds before loading the initially empty singleton registry. Replays loaded
before that point remain falsely orphaned because the later catalog load does not re-resolve
existing ReplayFile instances.
Code

GenHub/GenHub/Features/Tools/ReplayManager/Services/ReplayDirectoryService.cs[R176-178]

+        else
+        {
+            replay.CompatibilityStatus = ReplayCompatibilityStatus.Orphaned;

●●● Strong

This is a concrete lifecycle race producing stale user-visible status; recent accepted findings
address stale state and refresh consistency.

PR-#393
PR-#417

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The registry starts with empty dictionaries, replay loading immediately resolves misses as orphaned,
and the hosted service does not attempt its first load until after a 30-second delay. The ViewModel
retains the returned objects and contains no catalog-change re-resolution path.

GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcMappingRegistry.cs[16-18]

## Issue description
Replay compatibility is resolved before the CRC registry is guaranteed to be initialized, causing known replays opened during startup to be permanently labeled `Orphaned`.

4. Compatible ignores installed clients ✓ Resolved 🐞 Bug ≡ Correctness
Description
ResolveCompatibility derives Compatible solely from an absent CDN URL and never checks whether
the matched client is installed. A catalog entry with no download URL is therefore reported as
installed and ready even when that client is unavailable locally.
Code

GenHub/GenHub/Features/Tools/ReplayManager/Services/ReplayDirectoryService.cs[R172-174]

+            replay.CompatibilityStatus = string.IsNullOrWhiteSpace(match.CdnUrl)

+                : ReplayCompatibilityStatus.Downloadable;

●● Moderate

The enum wording supports the concern, but installation-state integration is architectural and lacks
a close precedent.

PR-#419
PR-#414

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The enum defines Compatible in terms of an installed client and Downloadable in terms of a
non-installed client, but the resolver only queries the CRC catalog and branches on CdnUrl; the
mapping model has no installation state.

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Compatibility status is inferred from CDN metadata rather than actual installed-client state.

## Issue Context
`Compatible` is explicitly defined as installed and ready, while `CrcMappingEntry` contains catalog metadata only. Integrate the installed game-client source when resolving a match; use CDN availability only after confirming that no matching installation exists.

5. Catalog replacement is non-atomic ✓ Resolved 🐞 Bug ☼ Reliability
Description
LoadCatalog clears three shared dictionaries independently and then repopulates them entry by
entry. Concurrent replay lookups can observe an empty, partial, or cross-index-inconsistent catalog
during every refresh and produce incorrect orphaned or fallback matches.
Code

GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcMappingRegistry.cs[R86-89]

+        _entriesByCrcPair.Clear();
+        _entriesByExeCrc.Clear();
+        _entriesBySha256.Clear();

Recent accepted concurrency/state-consistency fixes show reviewers accept findings preventing stale
or inconsistent shared state.

PR-#393

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The registry maintains three independent shared indexes, clears each separately, and invokes
RegisterEntry repeatedly to rebuild them. The background update service calls this replacement
while the singleton directory service can issue lookups.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Catalog refresh exposes partially replaced state to concurrent readers.

## Issue Context
`ConcurrentDictionary` only makes individual operations safe; it does not make clearing and rebuilding three indexes atomic. Build all indexes off to the side and publish one immutable state snapshot with a single atomic reference swap.

6. Fallback writes destroy valid cache ✓ Resolved 🐞 Bug ☼ Reliability
Description
SaveLocalFallbackAsync uses File.Create on the live fallback path, truncating the previous valid
catalog before serialization succeeds. An I/O failure or cancellation can therefore leave an empty
or partial file and eliminate offline recovery on the next update attempt.
Code

GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcCatalogUpdateService.cs[R134-136]

+            var filePath = Path.Combine(appDataPath, ReplayManagerConstants.CrcCatalogLocalFileName);
+            await using var stream = File.Create(filePath);
+            await JsonSerializer.SerializeAsync(stream, catalog, JsonOptions, cancellationToken);
Relevance

●●● Strong

Recent accepted reliability feedback favors preserving durable state and propagating cancellation;
atomic fallback replacement is a clear recovery fix.

PR-#385

ⓘ Recommendations generated based on similar findings in past PRs

Evidence
The save path is opened directly with File.Create before asynchronous serialization, while
ordinary failures are only logged and cancellation is allowed to propagate. Later offline loading
reads this same path and rejects invalid or empty content, so a failed save destroys the prior
recovery copy.

## Issue description
Saving a refreshed catalog truncates the last valid offline fallback before the replacement is complete.

## Issue Context
Serialize to a temporary file in the same directory, flush and close it, then atomically replace/move it over the live fallback. Clean up the temporary file on failure or cancellation while preserving the previous catalog.

Changes

Replay compatibility flow

Layer / File(s) Summary
Replay contracts and metadata
GenHub/GenHub.Core/Constants/..., GenHub/GenHub.Core/Interfaces/Tools/ReplayManager/..., GenHub/GenHub.Core/Models/...
Adds replay header, CRC catalog, mapping, compatibility, profile-operation, and launch-message contracts. ReplayFile and ReplayMetadata expose parsed and displayable compatibility data.
Replay parsing and CRC catalog runtime
GenHub/GenHub/Features/Tools/ReplayManager/Services/..., GenHub/GenHub/Resources/crc-mapping.json, GenHub/GenHub/GenHub.csproj, GenHub/GenHub.Tests/.../Services/...
Parses GENREP headers, indexes CRC mappings, refreshes catalogs from remote, cache, and local sources, embeds catalog data, and tests parser, registry, and fallback behavior.
Compatibility resolution and replay actions
GenHub/GenHub/Features/Tools/ReplayManager/Services/ReplayDirectoryService.cs, GenHub/GenHub/Infrastructure/DependencyInjection/ReplayManagerModule.cs, GenHub/GenHub/Features/Info/Services/MockToolServices.cs, GenHub/GenHub.Tests/.../ReplayDirectoryServiceTests.cs
Resolves replay compatibility, creates matching profiles, acquires required content, launches profiles, registers services, and updates mock implementations and service tests.
Launch state and installation behavior
GenHub/GenHub/Features/GameProfiles/..., GenHub/GenHub/Features/Launching/..., GenHub/GenHub/Features/GameInstallations/..., GenHub/GenHub.Tests/...
Adds profile launch and stop messages, synchronizes launcher state, improves manifest and installation resolution, and updates Steam backup preparation and cleanup behavior with tests.
Replay Manager actions and display
GenHub/GenHub/Features/Tools/ReplayManager/ViewModels/..., GenHub/GenHub/Features/Tools/ReplayManager/Views/..., GenHub/GenHub/Features/Tools/Views/ToolIcons.axaml
Adds profile and launch commands, replay metadata columns, compatibility badges, status-specific controls, and vector action icons.
CRC catalog generation tooling
scripts/generate_crc_catalog.py
Adds release crawling, archive inspection, checksum calculation, catalog merging, validation, and command-line output generation.

Project presentation conventions

Layer / File(s) Summary
Emoji-free presentation rules and updates
AGENTS.md, coding-style.md, docs/dev/ui-styling.md, GenHub/GenHub/Features/...
Prohibits Unicode emojis in project presentation and replaces existing UI, status, log, and map-tool icon usage with semantic text or resource-based icons.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 967da

This PR lets replay metadata select, download, persist, and launch game clients, but the current logic can substitute same-publisher or cross-game content, misclassify retail installations, and trust a mutable remote catalog without authenticity binding. Users could receive the wrong client or patch and launch an incompatible or unintended game setup, so the PR is not merge-ready until exact identity and trust-boundary checks are fixed.

A rabbit checks the replay trail,
CRCs align without fail.
Profiles bloom, and badges sing,
Clean icons mark each useful thing.
The catalog hops from cache to cloud.

Inline comments:
In
`@GenHub/GenHub.Tests/GenHub.Tests.Core/Features/Tools/Services/ReplayDirectoryServiceTests.cs`:
- Around line 30-38: Add tests in ReplayDirectoryServiceTests that configure
_mockManifestPool.GetAllManifestsAsync and drive GetReplaysAsync with stubbed
IReplayHeaderParser and ICrcMappingRegistry results, asserting the compatibility
status for Compatible, RequiresProfile, Downloadable, Orphaned, and Unknown
branches.

In
`@GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcCatalogUpdateService.cs`:
- Line 37: Replace the hardcoded ServiceName in
GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcCatalogUpdateService.cs:37
with ReplayManagerConstants.CrcCatalogCacheKey; in
GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcMappingRegistry.cs:202-203,
use ReplayManagerConstants.CrcCatalogLocalFileName for the embedded-resource
suffix; in
GenHub/GenHub.Tests/GenHub.Tests.Core/Features/Tools/Services/CrcMappingRegistryTests.cs:45,
remove the unused inline URL or replace it with an existing centralized test
constant.

In `@GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcMappingRegistry.cs`:
- Around line 117-119: Update RegisterEntry so replacing an existing ManifestId
removes all of that entry’s previous keys from PairMap, ExeMap, and ShaMap
before adding the replacement keys. Build the next immutable state consistently
with the updated AllEntries collection, ensuring old CRC pair, executable, and
SHA-256 lookups no longer return the replaced entry.
- Around line 52-53: The TryGetEntry fallback currently permits executable-only
matches; require both iniCrc and exeCrc to be present and return false when
either is absent. Update ResolveCompatibility to map this failed lookup to
Unknown rather than Orphaned, while leaving TryGetEntryByExeCrc available only
for explicit heuristic callers.

In
`@GenHub/GenHub/Features/Tools/ReplayManager/Services/ReplayDirectoryService.cs`:
- Around line 341-346: Update FetchAcquiredManifestIdsAndProfilesAsync to return
whether manifest/profile retrieval succeeded, preserving false on exceptions
instead of treating failed data as empty. In the caller, initialize the
compatibility status to ReplayCompatibilityStatus.Unknown and skip
ResolveCompatibility when retrieval is unresolved; only resolve statuses from
acquiredIds and existingProfiles when the result is successful.

In `@GenHub/GenHub/Features/Tools/ReplayManager/Services/ReplayHeaderParser.cs`:
- Line 63: Move the replay header layout values used by ReplayHeaderParser into
ReplayManagerConstants: define constants for the 16384-byte buffer, 28-byte
minimum header size, and the 6-byte magic plus 22-byte fixed-field sizing, then
replace the inline literals in ReplayHeaderParser with those centralized
constants while reusing the existing ReplayHeaderMagic and MaxReplaySizeBytes
definitions.
- Line 212: Update the player-name parsing around playerName to remove exactly
the single slot-type prefix character from parts[0], rather than trimming all
consecutive leading H, C, X, or O characters; preserve the remainder of the name
unchanged.

In `@GenHub/GenHub/Features/Tools/ReplayManager/Views/ReplayManagerView.axaml`:
- Around line 83-84: Update the compatibility badge Border near the
CompatibilityTooltip binding to set its Background from the status-driven
compatibility state, using the existing status-to-color resource or converter if
available. Preserve the current layout and tooltip behavior while ensuring each
compatibility status renders with its intended badge color.

In `@GenHub/GenHub/Resources/crc-mapping.json`:
- Around line 7-29: Resolve the duplicate authoritative CRC pair
0x401D89EA:0x76B251A3 without last-entry-wins behavior: in
GenHub/GenHub/Resources/crc-mapping.json lines 7-29, either remove the ambiguous
duplicate or represent Steam and EA as compatible manifest aliases in one
mapping; in
GenHub/GenHub/Features/Tools/ReplayManager/Services/CrcMappingRegistry.cs lines
167-168, update catalog loading to reject duplicates or preserve all aliases so
ReplayDirectoryService.ResolveCompatibility can select a matching acquired
manifest or profile.

In `@scripts/generate_crc_catalog.py`:
- Line 414: Update the output-directory creation logic in the catalog generation
flow to handle filename-only values such as crc-mapping.json without calling
os.makedirs with an empty path; create the directory only when
os.path.dirname(output_path) is non-empty, while preserving directory creation
for paths that include a parent directory.
- Around line 377-380: Update validate_catalog so every entry requires both
exeCrc and iniCrc, validating each against the existing eight-digit hexadecimal
CRC format and reporting missing or malformed values as validation errors.
Preserve the authoritative (exeCrc, iniCrc) pair requirement used by replay
lookup.

…move emojis

- Register base GameInstallation and GameClient manifests in manifest pool before creating replay profiles, ensuring profile launch validation succeeds.
- Populate EnabledContentIds with both GameInstallation and GameClient manifest IDs and resolve retail replays against the active installation client.
- Acquire missing third-party game clients and MapPacks (e.g. GeneralsOnline) via IContentOrchestrator before profile materialization.
- Remove all unicode emojis across views, ViewModels, logs, and plugins, replacing with vector StreamGeometry PathIcon controls.

382-382: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Copy UseSteamLaunch into CreateProfileRequest.

GameProfileSettingsViewModel.Commands.cs passes GameSettingsViewModel.GetProfileSettings() to GameSettingsMapper.PopulateRequest(CreateProfileRequest, UpdateProfileRequest). This overload omits UseSteamLaunch, so the create request leaves the selected setting unset. Add the adjacent mapping and a regression test.

762-765: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

A manifest or profile lookup failure still downgrades every compatibility status.

FetchAcquiredManifestIdsAndProfilesAsync catches the failure, logs a warning, and returns an empty acquiredIds set with an empty profile list. ResolveCompatibility then evaluates every replay against empty data, so IsClientManifestInstalled returns false at line 424 and DetermineUnconfiguredStatus reports Downloadable or Orphaned for content the user already installed. The badge shows "Download Required" for an installed client.

Return the retrieval outcome and leave CompatibilityStatus at Unknown when the data could not be read. Unknown already means the state is not determined.

🐛 Proposed fix to distinguish "not installed" from "unknown"
-    private async Task<(HashSet<string> AcquiredIds, List<GameProfile> Profiles)> FetchAcquiredManifestIdsAndProfilesAsync(CancellationToken ct)
+    private async Task<(bool Resolved, HashSet<string> AcquiredIds, List<GameProfile> Profiles)> FetchAcquiredManifestIdsAndProfilesAsync(CancellationToken ct)
     {
         var acquiredIds = new HashSet<string>(StringComparer.OrdinalIgnoreCase);
         var existingProfiles = new List<GameProfile>();
+        var resolved = true;
@@
         catch (Exception ex) when (ex is not OperationCanceledException)
         {
             logger.LogWarning(ex, "Failed to retrieve acquired manifests or profiles for replay compatibility matching.");
+            resolved = false;
         }
 
-        return (acquiredIds, existingProfiles);
+        return (resolved, acquiredIds, existingProfiles);
     }

Then skip ResolveCompatibility in ProcessReplayFileAsync when Resolved is false, leaving the status at Unknown.

Preserve mappings that share a manifest ID.

Line 467 uses manifestId as the only merge key. Lines 28-58 define two valid mappings with 1.104.retail.gameclient.zerohour but different iniCrc values. A merge keeps only the later mapping. A second generation against the same output removes the 0xDA2B4B18 / 0xFEAAE3F3 replay identifier.

Key merge state by a composite identity that preserves manifestId, exeCrc, and iniCrc. This also preserves catalog entries that share a CRC pair but map to distinct manifests. The PR objective declares the CRC pair authoritative.

[WARNING]: Companion manifest scan enables every publisher Patch/MapPack with no TargetGame or version filter

AddThirdPartyCompanionManifestsAsync enrolls every pooled manifest of the publisher with ContentType == Patch || MapPack. ContentManifest.TargetGame exists and replay.GameVersion is available at the call site (line 228), but neither filters the query. Consequences with the current provider landscape:

  • TheSuperHackers publishes patches for both Generals and Zero Hour (the manifest factory handles multi-game releases), so a Zero Hour replay profile can get the Generals patch enabled, and vice versa.
  • GeneralsOnline emits one patch.gamedata manifest per release; once two releases are pooled, both are enabled simultaneously in one profile, producing overlapping/conflicting content overlays in the materialized workspace.

Filter by m.TargetGame == replay.GameVersion and pin to the matched client's version (or the explicit DataPatchManifestId already handled at line 231) instead of blanket-enabling by publisher.

[WARNING]: Fallback silently substitutes a different client manifest for the replay's exact version

When the replay's exact ManifestId is absent from the pool (acquisition failed, user offline, provider delisted that build), this resolves to FirstOrDefault of any GameClient manifest of the publisher — no TargetGame and no version check. A Zero Hour replay can be bound to the Generals client of the same publisher, or to a different weekly build, while the constructed GameClient.Version still reports the replay's version — internally inconsistent profile metadata that is persisted via CreateProfileRequest and later launched, desyncing the replay. The previous code used replay.MatchedClient.ManifestId verbatim. Note that CreateProfileForReplayAsync_WhenGeneralsOnlineClient_AddsCompanionManifestsAsync enshrines this behavior: the replay declares 1.0605260.generalsonline.gameclient.zerohour but the assertion expects GameClientId == "1.82826.generalsonline.gameclient.60hz" (ReplayDirectoryServiceTests.cs:618). At minimum filter by TargetGame and surface the substitution to the user rather than doing it silently.

[WARNING]: Publisher fallback marks any same-publisher profile Compatible without a client-version check

IsProfileMatchingThirdParty now accepts a profile when only the publisher matches (PublisherType == publisher or any enabled ID containing ".<publisher>."). The data patch must match exactly (line 379), but the client version does not: with ~30 TheSuperHackers weekly builds in the CRC catalog plus per-release GeneralsOnline clients, a replay recorded on the 2026-06-05 weekly is reported Compatible — and launched — through a profile pinned to the 2026-08-21 weekly. That is precisely the in-game CRC/desync mismatch this feature exists to prevent, now presented behind a ready-to-play status. The previous code required an exact manifest-ID match. This fallback is also what launders the wrong-version substitution from ResolveThirdPartyClientManifestIdAsync into a Compatible status.

[SUGGESTION]: Case-sensitive List<string>.Contains amid otherwise case-insensitive ID comparisons

enabledContentIds is a plain List<string>, so this dedupe (and the DataPatchManifestId check at line 232) compares IDs ordinally case-sensitive, while every other ID comparison in the new code uses OrdinalIgnoreCase (lines 358-359, 366, 379, and the acquiredIds set built with StringComparer.OrdinalIgnoreCase at line 733). The substring filters at lines 510 and 540 (m.Id.Value.Contains("." + publisher + ".")) are likewise case-sensitive while their paired PublisherType checks are case-insensitive. If a catalog ID ever differs in case from its pool-normalized form, the same manifest is enabled twice. Use StringComparer.OrdinalIgnoreCase for the list (or a HashSet with that comparer).

[SUGGESTION]: Detection result discarded; call re-hashes executables without populating the installation's clients

DetectGameClientsFromInstallationsAsync returns DetectionResult<GameClient> and does not attach clients to the installation — attachment happens via installation.PopulateGameClients(...) inside GameInstallationService, which GetAllInstallationsAsync at line 179 already ran. As written, the call's only effect is re-registering client manifests in the pool, at the cost of a full re-detection (directory scan plus SHA-256 hashing of every game executable) on each CreateProfileForReplayAsync invocation, with any failure silently ignored. Consume the result (installation.PopulateGameClients(result.Items)), or drop the call since CreateAndRegisterInstallationManifestsAsync at line 194 already guarantees pool registration.

Assert the state changed by Receive(ProfileLaunchedMessage).

Receive(ProfileLaunchedMessage) sets the matching GameProfileItemViewModel properties through Dispatcher.UIThread.InvokeAsync, but this test only asserts Assert.NotNull(vm). Ensure the dispatched action completes, then assert item.IsProcessRunning is true and item.ProcessId is 45678.

Reuse the existing FilesAreEqual implementation instead of duplicating it.

This new static FilesAreEqual duplicates the private instance method already defined in the nested PreparationRollback class (same length check, same SHA256.HashData comparison). Two independent copies of this logic can diverge if one is updated later.

Have PreparationRollback call the new outer static method instead of keeping its own copy, since the nested class already has access to SteamLauncher members.

♻️ Suggested consolidation
