    // EquipmentTagsDarkBatch4 was RETIRED (2026-07-28) once its own unblock condition was examined. It read
    // "dark until Batch 4"; Batch 4 shipped as v3.0 and RETIRED the equipment-tag plan set rather than
    // lighting it, so every test wearing this reason was waiting on something that had already happened and
    // gone the other way. Each was resolved on its merits rather than left to read as pending work:
    //   - revived onto the raw/UNS shape that replaced the subject (the real-SDK dual-namespace
    //     materialisation E2E in AddressSpaceApplierHierarchyTests; the cluster-scoping rebuild and the
    //     four primary-gate write/alarm cases in Runtime.Tests),
    //   - folded into a live parity test whose corpus was widened to cover them (array + native-alarm
    //     intent, now in DeploymentArtifactRawUnsParityTests),
    //   - or deleted, where the subject itself is retired (equipment-namespace EquipmentTags, the
    //     dot-joint {{equip}}.X token — superseded by the slash-joint form in
    //     DeploymentArtifactEquipRefParityTests).

    // DiscoveryInjectionDormantV3 was removed with the injection path itself (§8.2, Gitea #507). The 18
    // tests it skipped were v2 characterization tests — they asserted an equipment-rooted graft
    // (EquipmentRootNodeId == "EQ-1") that v3 cannot produce, so they were deleted rather than unskipped.
    // Discovered raw tags are authored through the /raw browse-commit flow; IRediscoverable now surfaces a
    // re-browse prompt instead (DriverInstanceActorRediscoverySignalTests).
