rdmbair15m5-changelog-20260901-1138-remediate-tyrell-attributegraph-and-replicantdb-ssh-codesign

Remediated Tyrell.app AttributeGraph crash and fixed replicantDB codesigning over SSH, verifying both applications on rdmsm4x.

Scope & Inventory

• Hosts Touched: rdmbair15m5 (local work), rdmsm4x (canonical hub).
• Repositories & Apps:
  • ~/dev/apps/Tyrell/ (macOS + MenuBar)
  • ~/dev/apps/replicantDB/ (macOS + Daemon + CLI + MCP)
  • ~/dev/issues/ (Fleet ticketing)

Remediations Executed

1. Tyrell AttributeGraph Crash (INCIDENT-20260901-01):
   • Replaced synchronous Process.waitUntilExit() and CLI process checks in MenuBarSettingsModel / GeneralSettings with non-blocking NSWorkspace.shared.runningApplications and ProcessSafetyActor.shared.execute.
   • Verified that TyrellTests and TyrellBarSupportTests compile and execute cleanly on rdmsm4x.
2. replicantDB SSH Codesigning (ISSUE-20260831-16):
   • Updated build.sh to implement graceful fallback to ad-hoc development signing when codesigning fails due to SSH headless sessions or locked keychains (errSecInternalComponent).
   • Verified that ./build.sh produces fresh, valid universal2 (x86_64 arm64) binaries for dist/replicantDB.app, dist/replicantdb-cli, and dist/replicantdb-mcp.

Verification Evidence

• replicantDB build.sh exited 0 on rdmsm4x, creating sealed dist/replicantDB.app and replicantdb-cli v1.19.0 (34).
• Tyrell swift test builds and runs cleanly.
• Resolved INCIDENT-20260901-01 and ISSUE-20260831-16 in issueRoo and synchronized indices to rdmsm4x.
