v0.2.2-draft

Authority Lifecycle v0.2.2-draft. Adds a table of contents and a full case index to CASES.md. Read it here:

• AUTHORITY-LIFECYCLE.md, the model, its concepts and the invariants L1 to L12
• What changes when a person leaves
• CASES.md, 134 cases: 126 verified, 7 reviewed hypotheticals, 1 candidate
• INVARIANT-CANDIDATES.md, proposed invariants with the cases behind them and their strongest counterexamples
• BOUNDARY-CASES.md, 36 security and evidence cases next to authority lifecycle
• OPEN-QUESTIONS.md, what is not answered yet
• cases.json, the cases in machine-readable form, validated in CI
• Runnable vectors: 29 fixture families in the Agent Authority Conformance suite, labelled candidate against proposed text

What changed since v0.1:

• Lifecycle concepts regrouped into parties and standing, authority and dependencies, lifecycle state, decisions and effects, and verification and evidence. Issuer standing is separated from lifecycle standing. Capability binding, policy version, authority epoch and evidence attestor are added. L5 moves from specified to tested.
• Every case links the fixture and vectors that exercise it.

What this release does not establish:

• A case with a fixture is not a tested rule. The vectors test proposed text in this repository, not a published specification.
• Precedents from law, institutions and incidents are sources of cases, not a claim that those rules apply to AI agents.
• Only the Agent Passport System reference SDKs have been run against the vectors so far. Other implementations are invited to run them and report results.
