Engine raven-solana-live-scan@0.1.0 (vocabulary v4) · key
rvk_c2997e90215279c2 · evals /evals.json (30) · latest public blackbox:
2026-06-05, 9 pass 0 fail (keyed, vs production) · 50+ site tests.
Rules: failing eval = build order; new capabilities ship with evals; no
undocumented trust expansion. Engine work only from: measured feedback, beta
users, explicit coverage gaps, eval failures. Known limitations stay listed
in /quality-ledger.json until closed — never hidden.
