rdmpw3275m-changelog-20260923-1032-tyrell-feat-20260901-03-standalone-architecture

One-line summary: Certified and resolved Tyrell Standalone Zero-Dependency Architecture, Keychain Multi-Account Pool & agy Ingestion (FEAT-20260901-03), verified with 39/39 tests passing across Intel macOS 26.7.1 and Apple Silicon macOS 27.0.

Scope

• Hosts affected: rdmpw3275m (Intel Xeon W-3275M scratch host), rdmsm4x (M4 Max canonical dev hub).
• Projects affected: apps/Tyrell.
• Tickets affected: FEAT-20260901-03 (RESOLVED).

Components Verified

1. Safety Invariants:
   • ProcessSafetyActor: elimination of synchronous Process/NSTask blocking on Thread 0, enforcing strict timeouts and process tree reaping.
   • StorageExclusivityActor: atomic write guarantees and file locking.
   • PowerGovernanceActor: AC-power awareness, thermal throttling guards, and lifecycle refcounting.
2. Standalone Engine:
   • TyrellBootstrap: dynamic Application Support sandbox bootstrapping, SQLite schema generation, and zero external shell script reliance.
3. Multi-Account & agy Ingestion:
   • KeychainCredentialPool: secure multi-account credential storage supporting >= 2 accounts per provider with automatic failover ladder.
   • AntigravityTelemetryEngine: ingestion and decoding of protobuf session streams, SQLite conversation stores, and statusline quota metrics.
4. 6-Persona Audit Panel:
   • PersonaEvaluationSuite: structured automated evaluation across 6 distinct engineering personas (Pro Mac User, Pro Mac/AI Dev, AI Dev, Apple Platform Engineer, OpenAI Developer, and Antigravity Engineer).
