Four ways the tally could be reached by something that is not a quorum.
A peer that is not a validator could vote. The signed path never had to ask:
VerifyVote resolves the voter's key out of the set at the block's epoch, so an
id that is not in the set has no key and its vote dies there. The
transport-authenticated path has no signature to resolve and the tallies are
keyed by NodeID, so it counted distinct PEERS. A peer need not be a validator to
connect, and its NodeID is a hash of a certificate it makes for itself, so
distinct peers are free to mint. Worst on the reject road, which has no cert in
front of it and commits inline.
One node could vote repeatedly. The engine behind consensus.NewChain appended
votes to a slice and compared its length to alpha, so a single node reached
quorum alone. Votes are now keyed by voter: a second vote from a node replaces
its first. The Config comment called alpha "the number of votes", which is the
same mistake written as prose.
A cert for one block could finalize another. The outer envelope ids are the one
part of a position no signature covers — the signed identity is the inner
canonical — so the id we looked the block up by proves nothing. Re-point it at a
sibling at the same height and a genuine cert asks us to accept a block it does
not name. The arm that finds a wrapper now checks the canonical, which the arm
that finds none already did.
And a node could go silent on a block it still holds. Abandonment stops
re-soliciting peers who cannot vote; the slot sweep read it as "do not vote
either", so the settle pass never offered the slot and the height was never
signed while the block sat pending and undecided. It is also a per-node clock
decision, so it dropped nodes out of the tally at different times. One meaning
now, and no flag to select the other.
Also: a seed below the node's own applied head is refused rather than planting
the certified frontier under it, and the phantom-floor reconcile is deleted —
a repair for a bug already fixed, called by nothing, that asked an operator to
verify a fleet-wide height by hand before it would prune the equivocation
bindings.

PQ mode is binary. The profile registry is collapsed to three
canonical bundles:
0x01 ProfileStrictPQ ("STRICT") — production PQ chains
0x02 ProfilePermissive ("PERMISSIVE") — testnet / devnet
0x03 ProfileFIPS ("FIPS") — FIPS-aligned superset
Removed pseudo-profiles: HybridProfile, ClassicalProfile, BLSProfile,
ZooStrictPQProfile, HanzoStrictPQProfile, QuasarStrictPQProfile,
AnnulusStrictPQProfile. Chains that need classical primitives pin
ForkClassicalCompatUnsafeProfile (0x80) at the byte layer and own
the audit consequence.
(*ChainSecurityProfile).IsPQ() is the single canonical predicate.
Profile string surface tracks the byte registry exactly: "strict",
"permissive", "fips".
Cross-brand scrub: dropped "Hanzo mesh" doc-comments in pq_mode.go
+ pq_mode_test.go + witness_floor_test.go in favor of "Lux mesh".
Dropped Lux/Zoo/Hanzo enumeration in account_id.go. account_id_test.go
uses fork byte (0x80) instead of zoo/hanzo profile IDs. qblock.go
references LP-0079 instead of cross-org HIP path.

Complete removal of Avalanche Snow* family and replacement with Lux-native
consensus using Photon → Wave → Focus → Prism → Quasar flow.
Breaking Changes:
- Removed: All Snowball/Avalanche consensus references (policy violation)
- Added: LuxConsensus using Wave, Focus, Prism protocols
- Fixed: RecordPoll to use independent polls (reset votes each round)
- Fixed: Confidence tracking for all processing blocks, not just voted
New Files:
- engine/lux_consensus.go - Core Lux consensus implementation
- engine/chain/consensus_real.go - Real chain consensus
- engine/dag/consensus_real.go - Real DAG consensus
- engine/dag/vertex.go - DAG vertex implementation
- engine/pq/crypto.go - Post-quantum cryptography
Test Results:
- Chain: 28/29 tests PASS (1 pre-existing flaky test)
- DAG: 16/16 tests PASS
- PQ: 15/15 tests PASS
- Wave: 18/18 tests PASS
Note: TestRecordPollTransitiveVotingTest is flaky due to Go map iteration
randomness (predates this change). All other tests pass consistently.
Zero Snowball references remain. All consensus now uses Lux protocols.
