rdmbair15m5-changelog-20260916-1358-updateroo-peer-bottle-exchange

Summary: Implemented peer-to-peer Homebrew bottle exchange in updateRoo across Bonjour and Tailscale (FEAT-20260901-47), enabling Intel Macs to resolve and install unbottled binaries from peer nodes without compiling.

Scope

• Hosts: rdmsm4x (canonical dev root), rdmpw3275m, rdmpw3265m, rdmbair15m5
• Repositories:
  • apps/updateRoo (commit fe26d29)
  • issues (commit 4db6ab8)

Files Touched

1. apps/updateRoo/Sources/UpdateRooCore/Fleet/PeerBottleExchangeCoordinator.swift (New actor managing discovery across Bonjour/Tailscale, binary compatibility matching for Cascade Lake / x86_64 / arm64, SHA256 cryptographic verification, and bottle download/installation).
2. apps/updateRoo/Sources/UpdateRooCore/Scanners/HomebrewScanner.swift (Integrated peer bottle resolution into applyUpdates to resolve unbottled formulae directly from peer hosts prior to triggering source builds or safety guard deferrals).
3. apps/updateRoo/Tests/UpdateRooTests/PeerBottleExchangeTests.swift (Added 7 unit tests covering Cascade Lake / x86_64 / arm64 compatibility checking, SHA256 checksum hashing, error descriptions, and peer discovery).
4. issues/resolved/FEAT-20260901-47-updateroo-peer-bottle-exchange-over-exis.md (Resolved ticket with full empirical evidence).
