Summary

Re-resolved bitROO FEAT-20260831-51 and XEntropy FEAT-20260831-65 with verified empirical application test and binary evidence, implemented the prerequisite credential risk-tier and blast-radius classification data model for XEntropy (FEAT-20260901-16), and synchronized fleet agent coordination state.

Milestone 1: bitROO Ticket Re-Resolution (FEAT-20260831-51)

• Swift 6 Compilation:
  • swift build executed in /Users/richh/dev/apps/bitROO (0.52s, rc=0).
  • swift build -c release executed (7.54s, rc=0) on Swift 6.4 (swiftlang-6.4.0.33.1).
• Test Suite Pass Count:
  • swift test executed passing 9/9 Swift Testing tests in 0.005s with 0 failures:
    • Test "every host gets a distinct label" passed.
    • Test "genuinely identical names do not crash or hang" passed.
    • Test "a canvas encodes to a GIF small enough to push" passed.
    • Test "labels fit the panel" passed.
    • Test "a single name is left alone" passed.
    • Test "the fleet scene fits inside the panel" passed.
    • Test "the two-column grid shows ALL six hosts, not four" passed.
    • Test "the two adversarial pairs are actually told apart" passed.
    • Test "labels stay distinct at every width the layouts actually use" passed.
• Universal Binary Verification:
  • lipo -archs on build/bitroo, .build/out/Products/Release/bitroo, and build/BitRoo.app/Contents/MacOS/BitRoo verified x86_64 arm64 (Universal2).
• Standalone ECSSystem Linkage:
  • Confirmed standalone library import via commit e52e475 (TASK-20260904-14) and git grep "ECSSystem":
    • Package.swift links ../../lib/ECSSystem
    • Sources/BitRooCore/TidbytAPI.swift imports ECSSystem
• Ticket Resolution:
  • Ticket resolved via ticket resolve FEAT-20260831-51 with empirical verification evidence.
  • Verified ticket show FEAT-20260831-51 reports status: resolved.
  • git status in /Users/richh/dev/apps/bitROO verified clean.

Milestone 2: XEntropy Conformance & Ticket Re-Resolution (FEAT-20260831-65)

• Test Suite Pass Count:
  • Full test suite executed in /Users/richh/dev/apps/Xentropy/app:
    • XEntropyTests: 54 tests executed, 0 failures.
    • XEntropyGatewayTests: 19 tests executed, 0 failures.
    • XEntropyCoreTests: 188 tests executed, 0 failures.

  • Verified ticket show FEAT-20260831-65 reports status: resolved.

Milestone 3: XEntropy Credential Risk-Tier / Blast-Radius Model (FEAT-20260901-16)

• Data Model Implementation:
  • Added CredentialBlastRadius enum (accountWideOrBilling, registrarOrDNS, certificateOrTLS, scopedProject, lowImpactRevocable, unknown).
  • Added explicit classification property on CredentialMetadata and CredentialMetadataProjection strictly defaulting to .unknown.
  • Added setClassification method to CredentialCatalogWriting and SQLiteCredentialCatalog.
  • Enforced strict authorization: non-owner callers (.claude, .localCLI, unprivileged .localApp) are rejected with CatalogStoreError.forbidden.
• Fail-Closed Rotation Planning:
  • Added RotationPlanBlockerKind.classificationUnknown = "classification_unknown".
  • Updated RotationPlanner.blockers(): when record.classification == .unknown, rotation planning is unconditionally blocked with .classificationUnknown and deferred to .ownerAttendedDeferred.
• Unit Tests Added:
  • testCredentialBlastRadiusEnumConformanceAndCases
  • testCredentialMetadataClassificationStrictlyDefaultsToUnknown
  • testCredentialMetadataDecodesDefaultUnknownWhenFieldOmitted
  • testUnclassifiedCredentialUnconditionallyBlocksRotationPlanningViaClassificationUnknown
  • testClassifiedCredentialsAreNotBlockedByClassificationUnknown
  • testCallersWithoutOwnerPrivilegesRejectedWhenSettingClassification
• Full Suite Verification:
  • swift build clean (0 warnings, 0 errors).
  • swift test across all targets passes 326/326 tests with 0 failures and 0 regressions.
