Evidence Package archive

Record console · synthetic fixtures · S(c) re-query values preview the forward-committed counterfactual mode (Rules P.5); the reference SDK captures self-reported S(c) today · the live console runs in your environment under engagement

When an instrumented agent transacts, Verdra captures four pieces of proof and seals them here.
If a transaction is ever challenged, this is the archive you'd open.

Active dispute DRP-2026-0044

Opened 2026-07-03 · Counterparty: vendr-fulfill-2 (Vendr Inc.)

Counterparty alleges: Goods received did not match PO-44219; pallet 14 contents short by 6 units.
Resolution path: Counsel review → the venue elected in the transaction's LCP clause: a Verdra-compliant venue (Verdra Forum, in formation) or an incumbent (AAA-ICDR / JAMS / SIAC / scheme arbitration). Verdra Record is the evidence channel; the venue is elected separately.

Capture rules

5 rules · all active

R01Always capture all 4 strataactive

Every instrumented agent action seals S(a) Transaction, S(b) Configuration, S(c) Behavior profile, S(d) Mandate. No opt-out.

R02S(c) behavior re-queryforward

Where the runtime preserves state, counterfactual re-queries compute modal action, runner-up, and replay sharpness. Full counterfactual evidence is forward-committed under Rules P.5; otherwise S(c) is self-reported and the limitation is disclosed.

R03Hash + timestamp before dispatchactive

BLAKE3 hash computed before the agent action dispatches to counterparty. RFC 3161 timestamp is deferred in V0.1 (forward commitment per Rules P.5); the hash precedes action either way.

R04Authority ceiling checkactive

S(b) records the agent's authority ceiling from configuration. Actions exceeding authority flagged for human review before dispatch.

R05Storage redundancyactive

Every sealed Evidence Package written to primary WORM bucket + off-region replica. Integrity re-verified daily.
