Use the agreed exportSigSetHash sidecar map, not the live ExportSigCollector, as the network-mode ttEXPORT signer snapshot. Preserve export convergence state through RNG onPreBuild cleanup so buildLCL apply can see the gate result, and require a UNLReport-backed validator view before non-standalone Export finalization. Add regression coverage for agreed-vs-live collector mutation and onPreBuild export-state preservation.
A drift review (10-section adversarial pass + skeptical verification) found the design doc had fallen behind two recent code changes: the UNLReport-only gate (8368e12ab) and the F1 active-view alignment filter (fb9e2710c).
- Fallback Semantics: add the second fallback trigger -- a non-UNLReport-backed view mints consensus_fallback regardless of alignment.
- Validator Set And Quorum: note the config-fallback view is !fromUNLReport and forces consensus_fallback entropy.
- Entropy Alignment Rules: state the UNLReport precondition for non-fallback tiers; correct the alignment-count formula to the active-view-filtered count (non-active proposers and a non-active local +1 excluded -- the F1 fix); separate the two distinct counts (the peer-alignment GATE count vs the agreed entropySetMap_ leaf count that drives the tier LABEL); flag the explicit-final unfiltered exception.
- Worked examples: note they assume a UNLReport-anchored view (else all fall back).
- Export Principles: document that export success also requires full observation (peersSeen == txConverged), not just quorum alignment.
- Review Checklist: add items for the UNLReport-anchored-tier and alignment-count-universe (F1) invariants.
Doc-only. Raw drift findings kept in .ai-docs (gitignored).
The explicit-final proposal path counts participants/alignment over the unfiltered trusted-proposer set (ctx.peerPositions) plus an unconditional local +1, not the active validator view -- the same gap the F1 fix closed for the main entropy gate (inspectTxConvergedSidecarPeers). It is default-off/experimental with no robust timing model found (per the existing TBD, may never ship); if it is ever enabled it must apply the same active-view membership filter. Comment-only.
Follow-up to F1 (fb9e2710c).
