// Interop smoke test: a single project sent/received through both the hgweb and

// store files the other last wrote. Verifies the two front the same repo
// consistently across protocols.
//
// Note: this does NOT guard the hgweb/hgresume file-ownership issue behind PR #2590.
// Freshly-created repos get setgid, group-shared (660) store files owned by the
// shared www-data group, so it doesn't matter whether hgresume runs as root or
// www-data — either server can write the other's files. Reproducing that bug needs
// a repo without group-shared perms, which a new project never has.

// Create a fresh project and push it to the server via the first protocol.

Compare tip hashes instead of commit dates.

GetProjectLastCommit uses Unix-second precision, so commits in the same second can make BeAfter fail. Read the tip node and assert that it changes after each send/receive, as in SendReceiveAfterProjectReset (Lines 118–119 and 126–127).

In `@backend/Testing/SyncReverseProxy/SendReceiveServiceTests.cs` around lines 118
- 119, Update the assertions around GetProjectLastCommit in
SendReceiveServiceTests to compare the returned tip node/hash rather than commit
timestamps. Follow the existing SendReceiveAfterProjectReset pattern and assert
that the tip node changes after each send/receive, avoiding Unix-second
precision issues while preserving the intended commit-advance checks.

// Modify again and push via the first protocol, so it in turn appends to the files
// the second protocol just wrote — completing the round trip.

var lastCommitAfterThird = await _adminApiTester.GetProjectLastCommit(projectConfig.Code);
lastCommitAfterThird.Should().BeAfter(lastCommitAfterSecond!.Value);
