1. Scope & Deliverables

R1. Build 20 Worktree Isolation & Lineage Anchoring

• Worktree established on rdmsm4x: /Users/richh/dev/_worktrees/tyrell-build20-supervisor-approvals-20260903.
• Branch agy/tyrell-build20-supervisor-approvals-20260903 anchored strictly to Build 19 commit c7093025efefce3560719c01660a75db1f8991ad.
• Merge base configured via git config branch.agy/tyrell-build20-supervisor-approvals-20260903.gh-merge-base c7093025efefce3560719c01660a75db1f8991ad.
• Canonical main at rdmsm4x:~/dev/apps/Tyrell remains clean and completely untouched at 79e30341b235d1be52a72671938c2da82d5230c4.

R2. Supervisor Approval Queue & Interactive Permission Policy Engine (FEAT-20260903-03)

• Sources/TyrellCore/Approvals/ApprovalModels.swift: Implemented 4 permission modes (supervised, autoEdits, auto, fullAccess), 5 decision actions (acceptOnce, acceptForSession, acceptAlways, declineWithFeedback, cancelTurn), priority levels, status types, and audit records.
• Sources/TyrellCore/Approvals/ApprovalQueueActor.swift: Thread-safe Swift 6 actor managing priority queueing, timeout auto-expiration, in-memory session allowlists, and persistent SQLite WAL storage via ecs0lib.ECSSQLite (projection_pending_approvals).
• Sources/tyrelld/ApprovalRoutes.swift & Daemon.swift: Daemon REST endpoints GET /api/approvals (with status filtering and priority sorting) and POST /api/approvals/{id}/decision with JSON validation and audit logging.
• Sources/tyrell-app/ApprovalsDestination.swift: Liquid Glass UI (SignalGlassTheme) with interactive approval cards, syntax-highlighted diff viewers, command inspector, and 1-click decision action buttons.
• Adversarial defect caught and remediated: Handled unquoted SQL string literal bug in crash recovery.

R3. Real-Time Control Surface & Token Streaming (FEAT-20260903-05)

• Sources/TyrellCore/ChatModels.swift: Implemented ChatStreamChunk, ChatStreamChunkKind, ChatStreamParser, and ChatDualDeliveryBuffer actor with MAX_BUFFERED_CHARS = 24,000 and the Strict Immediate Flush Invariant upon boundary events (toolStart, toolFinish, approvalRequested, finish).
• Sources/TyrellCore/Safety/ProcessSafetyActor.swift: Implemented cancelTurn(pid:) dispatching Darwin kill(pid, SIGINT) for turn cancellation.
• Sources/tyrelld/ChatStreamRoutes.swift: Implemented Server-Sent Events (SSE) route GET /api/chat/conversations/{id}/stream delivering live tokens, tool boundaries, and human approval events.
• Sources/TyrellAppSupport/ChatTransport.swift: Added streamConversation(_ id: String) -> AsyncStream<ChatStreamChunk> on ChatTransport protocol and TyrellDaemonChatTransport using URLSession.bytes(for: request) with zero dropped tokens.
• Sources/tyrell-app/AgentsPanel.swift: Fixed 3-line card subagent roster integrated into FleetChatView.swift with 5-tier stacked token gauges (Total, Input, Cached Read, Output, Thinking), live elapsed timers, semantic status tones, and 1-click turn cancellation via SIGINT.

R4. Test Verification & Fleet Coordination

• Zero warnings and zero errors under Swift 6 strict concurrency (0 errors, 0 warnings).
• Independent test execution verified 478 tests passed with 0 failures:
  • TyrellCoreTests: 385 tests (355 Swift Testing + 30 XCTest).
  • TyrellAppSupportTests: 93 tests (82 Swift Testing + 11 XCTest).
• Fleet tickets FEAT-20260903-03 and FEAT-20260903-05 closed as resolved on canonical ticket store.
• Fleet coordination messages sent and synced across all 6 hosts via agent_msg.zsh sync.

2. Evidence & Verification

• Release Commit: 116f7ea5f9889004ddda5cd6aa1e65fed5e62619 on rdmsm4x.
• Working tree: clean (nothing to commit, working tree clean).
• Independent Post-Victory Auditor: 01a7d2c1-1f9d-4be5-a6a5-0e5d8796cb3a — VERDICT: VICTORY CONFIRMED.
