Agent Surety

Post a surety bond behind an agent's promises. principal is a positive integer in minor units; expires_at is the ISO-8601 coverage window end. The bond fee (2% default) is computed and frozen at post.

Mark a POSTED bond ACTIVE (idempotent). funding_ref links the payment rail transaction that funded the stake.

File a claim against an ACTIVE bond. Claims pay out ONLY when an arbitration ruling upholds them (see slash_bond).

Execute an arbitration ruling against a claim. Requires the ruling's case id + content hash from agent-arbitration — no ruling, no slash; a given ruling pays at most once. Payout caps at the bond's available balance (over-claims exhaust the bond).

Release the remaining stake to the principal after the coverage window elapses — refused while any claim is still open.

Current record for a bond (state, balances, claims, audit head).

List bonds, optionally filtered by state (POSTED|ACTIVE|RELEASED|EXHAUSTED).

Validate the tamper-evident audit hash chain for a bond.

Underwrite a surety bond: deterministic actuarial premium quote from a counterparty's track record (attestations, notarized deliveries, completed bonds lower the rate; slashes raise it or decline outright). Integer-only model uw-v1; the returned quote_hash lets any party recompute and ve
