Isolation tools added: Cleanroom (Buildkite), container-use (Dagger),
Docker sbx, Anthropic srt.
Governance/pre-action layers added as a separate section: Microsoft
Agent Governance Toolkit (per-agent DID + YAML policy + trust score),
Open Agent Passport (declarative policy + cryptographic audit).
Comparison table: 14 → 14 columns; new Agent-tailored policy row added.
Second addendum covers competitive position on role-tailoring, Docker
sbx as new DX-class competitor, and borrowable ideas (trust-score decay,
live network TUI, cryptographic audit chain).
Discourse note: adds Per-agent role tailoring to "What it covers well"
with competitive comparison table across 9 tools.
