Transaction Science a822ec312d joulehook: conformance/v1 vectors + meter-seam wiring doc
Publish reproducible conformance vectors (every TX standard has conformance/):
decisions.json (the exact per-host decision encoding each gate adapter must emit
for a granted vs ungranted call), deny-receipt.hex (the byte-deterministic sealed
JCR-1 deny receipt — 598 bytes, identical every run under the reference gate's
fixed dev keys), and receipt.json (what it must decode+verify to under the
steward key). Adds the enforcing-meter wiring to INSTALL (point OpenAI-API hosts'
base_url at mesh-openai for measured joules + an enforced ceiling; Claude Code's
Anthropic-shaped front is a documented follow-up).

"`deny_reason: wrong-resource` is the JCP runtime's reason: the action's content-addressed resource did not match any held capability's audience (SPEC §3.3). The gate never asked the model.",
