rdmpw3275m-changelog-20260921-1645-tyrellbar-orchestrator-surfaces-feat-20260905-11

Implemented orchestrator telemetry surfaces in tyrellbar (FocusPanel & NSStatusItem) for host pressure levels, active holds with live countdown, and conflicts needing human intervention.

Scope

• Hosts: rdmpw3275m (worker), rdmsm4x (canonical hub)
• Project: apps/Tyrell (Targets: TyrellCore, tyrelld, TyrellBarSupport, tyrellbar)
• Ticket: FEAT-20260905-11 (Parent: EPIC-20260905-01)

Exact Files Touched

• Sources/TyrellCore/Telemetry/HostPressureEvaluator.swift (New): Evaluates local host load ratio and thermal state on 0..4 scale (Nominal..Critical) and cross-references peer fleet load guard cache.
• Sources/TyrellCore/Approvals/ApprovalModels.swift: Added SessionHoldDiskStorage.loadActiveHolds(dir:now:) for synchronous, lock-free hold reads.
• Sources/tyrelld/ControlServer.swift: Exposed GET /api/orchestrator/holds and GET /api/orchestrator/pressure on port 43118.
• Sources/tyrelld/ApprovalRoutes.swift: Added GET /api/orchestrator/pressure on port 43117.
• Sources/TyrellBarSupport/OrchestratorModels.swift (New): ActiveHoldPresentation, HumanConflictPresentation, OrchestratorSnapshot.
• Sources/TyrellBarSupport/OrchestratorEndpointClient.swift (New): Pure HTTP client polling /api/orchestrator/pressure, /api/orchestrator/holds, and /api/conflicts.
• Sources/TyrellBarSupport/FocusPanelState.swift: Added .orchestrator section to FocusPanelSection.
• Sources/tyrellbar/OrchestratorSection.swift (New): SwiftUI section rendering host pressure cards, active holds with live TimelineView countdowns, and conflicts needing human arbitration.
• Sources/tyrellbar/FleetSection.swift: Integrated host pressure badges into FleetHostDisclosure.
• Sources/tyrellbar/OverviewSection.swift: Added OrchestratorAttentionBanner surfacing active holds and high/critical pressure.
• Sources/tyrellbar/StatusFeed.swift: Added orchestrator: OrchestratorSnapshot and 2-second background polling task.
• Sources/tyrellbar/StatusItemController.swift: Integrated orchestrator critical alerts into StatusMeterPlanner.plan.
• Tests/TyrellBarSupportTests/OrchestratorModelsTests.swift (New): Unit tests for active hold countdown calculations, host pressure level evaluation, and snapshot alerts.
• Tests/TyrellBarSupportTests/FocusPanelStateTests.swift: Updated for .orchestrator section.
• Tests/TyrellCoreTests/HostPressureEvaluatorTests.swift (New): Unit tests for HostPressureEvaluator.

Verification Evidence

• swift build --target tyrellbar --target tyrelld --target TyrellBarSupport: Succeeded with 0 errors.
• swift test --filter TyrellBarSupportTests: 46 tests passed (0 failures).
• swift test --filter HostPressureEvaluatorTests: 2 tests passed (0 failures).
• swift test --filter SessionHoldDiskStorageTests: 2 tests passed (0 failures).
• swift test --filter ConflictDetectionTests: 15 tests passed (0 failures).
• Commit a8f25f6 merged via fast-forward on rdmsm4x:~/dev/apps/Tyrell and pushed to fleet (git.ecs0.net:git/apps/Tyrell.git) and backup (github.com/richhdoty/rdmsm4x-dev-apps-tyrell.git).

Compliance & Architecture

• AD-1 Decoupling: Zero direct references to TyrellCore actor singletons in tyrellbar. All telemetry fetched over localhost HTTP.
• Zero frame-rate degradation in the menu bar row: StatusMeterPlanner.plan uses pure in-memory projections.
• Resolved ticket FEAT-20260905-11 in fleet ticket database and broadcast via agent_msg.zsh.
