zeekayandHanzo Dev f1810d9112 Merge main: take the extracted cert design, keep the re-cut corpus
Two lineages refactored the same certificate path at once. This branch fixed the
BLS length inversion in place — the aggregator declared a 48-byte G1 signature
and sliced every 96-byte G2 vote down to it, so the aggregate was the error
path's zero bytes and forty validators voting with no signatures produced a
certificate that verified. Main went further and deleted the aggregate path
entirely, moving the per-key check into cert.rs, where a certificate is verified
against one public key per signature and keys are never summed.

Deleting the class beats fixing the instance, and main's version arrives with the
test that proves it: rogue_key.rs builds the Boneh-Drijvers-Neven forgery, shows
the four keys really do sum to one the attacker holds, and then shows it buys
nothing. So the Rust crate is main's.

Resolving that file by date would have taken this branch's lib.rs and left
cert.rs orphaned: main declares the module, this branch does not, and the new
test would not have resolved lux_consensus::cert at all.

The corpus stays this branch's. It was re-cut for the seed encoding, and the Go
definitions that generate it are here; main's is smaller because it de-duplicated
an older cut. Both languages read the re-cut one and agree.

Go: conformance and engine/chain green. Rust: 8 suites, 70 tests, 0 failures.

zeekayandHanzo Dev b0f6a338e7 consensus: give the epoch seed a domain and write its fields at their lengths
The seed preimage was be64(epoch) || chain_id || prev_block_hash, written end
to end. Nothing recorded where one field stopped and the next began, so the
boundary slid: DeriveEpochSeed(1, "chain-A", "") and DeriveEpochSeed(1,
"chain-", "A") are one seed. Machine-checked, both are
c89a52... under the old encoding.

That is not only untidy. The seed decides alpha, the count of votes a round
accepts on, and the input that makes it unpredictable is the parent hash --
the one value nobody holds until the previous epoch finalizes. Under a
concatenated preimage a chain that names itself lux-mainnet||H binds no parent
at all and still derives the seed lux-mainnet derives at parent H. The chain id
is a name the chain picks for itself; the parent is not. Trading one for the
other gives away the whole reason the parent is an input.

So every variable-length field is now written at its length, and the digest is
taken under a label of its own:

    domain || be64(epoch) || be64(len(chain_id)) || chain_id
           || be64(len(prev_block_hash)) || prev_block_hash

with domain = "lux.consensus.fpc.seed". Lengths make the preimage read back
apart into exactly the triple that produced it, which is injectivity stated as
something a machine checks rather than something a comment claims:
TestOneTripleReachesOnePreimage parses each preimage back and compares. The
domain keeps this digest from colliding with any other the protocol takes over
similar bytes.

EpochSeedPreimage is exported because the corpus records the bytes, not only
the digest. Two implementations can agree on every digest in a corpus and still
disagree on the first case that is not in it; they cannot, if they agree on
what they hashed. The oracle asks the package for the preimage rather than
rebuilding it, so a vector is never a second copy of the encoding it records.

pkg/rust carries the same change, and the same reason: it is the crate the
Rust conformance harness holds against these vectors.

zeekay 1776e41421 consensus: derive the FPC seed instead of drawing it
engine/driver.go filled the FPC seed from crypto/rand, so every node ran a
different threshold schedule. The threshold is the count of votes a round must
see before it moves, which means two honest validators sampling the same
committee were demanding different majorities of it: measured over 200
instances at k=20, the phase-1 threshold came out 11, 12, 13, 14, 15 and 16.

The seed is now DeriveEpochSeed(epoch, chain, parent), which every validator
computes alike and none can compute ahead of time — the parent hash is only
known once the previous epoch has finalized. The epoch arrives through
WithEpoch; a driver told no epoch derives the genesis epoch, which is a real
value rather than a draw. Sampling randomness is untouched: which peers a node
draws is deliberately its own business, what majority it then demands is not.

Wave and Driver gain Threshold(phase) so the number can be asked for. It is
the one number two implementations must agree on to agree at all, and a test
that cannot read it can only assert agreement rather than measure it.

zeekayandHanzo Dev e808906131 the corporate name is Lux Industries Inc
Lux Partners Limited is not the entity behind this work. Every place the
old name stood — copyright lines, site footers, brand config, legal and
compliance text — now names the company that actually holds it.

lux.fund is the exception and is not renamed to match: that site belongs
to Lux Assets Management LLC, a different company, and it says so.

Two kinds of line were left for a person rather than rewritten. A dated
news item recording that Lux Partners Limited was established in the Isle
of Man is a historical fact, and renaming it would falsify the record. And
a sentence asserting that the company is domiciled in the Isle of Man is a
claim about a jurisdiction, not a name — an Inc or an LLC is not an Isle
of Man company, so swapping the name there would assert something untrue.

zeekayandHanzo Dev 854998852a consensus: a decision needs evidence; unbreak the build
Five defects. The first four let a decision be reached on evidence never
gathered; the fifth is that main does not build.

**wave.Tick rounded the vote threshold down.** `int(float64(K) * Alpha)`
truncates: K=20 Alpha=0.69 is 13.8, so 13 votes of 20 cleared a threshold that
config.DefaultParams declares as AlphaPreference 14 — 65.0% on a chain
configured for 69%. Mainnet gave 14 where 15 is declared, testnet 7 where 8 is.
config.AlphaForK and fpc.Selector.SelectThreshold both round up; only this path
did not. Now math.Ceil.

**wave.New validated nothing.** Beta = 0 makes `Count >= Beta` in Tick true
before a vote is counted; K = 0 or Alpha = 0 puts the threshold at 0, which
yesVotes = 0 already meets. All three are zero values, so a Config missing a
field decided immediately. New refuses each. Alpha is checked only when FPC is
disabled, since the selector derives the threshold from ThetaMin/ThetaMax
otherwise — an existing FPC test passes Alpha 0 legitimately and caught the
first, over-strict version of this check.

**ray and field discarded that error.** Both NewDriver functions defaulted on
`== 0`, so a negative PollSize or Beta, or an Alpha outside (0, 1], reached
wave.New's refusal — and because the error is dropped, the Driver kept a zero
Wave whose nil state map panics on the first Tick. Verified: with the old
defaulting the new test panics with "assignment to entry in nil map". Both now
normalise the whole invalid range.

**engine.NewLuxConsensus clamped a negative beta to 0.** The comment said
"ensure beta is non-negative for uint32 conversion" — that fixes the
representation and breaks the meaning. NewLuxConsensus(20, 15, -5) built a
driver whose wave decides with Count = 0, and a test asserted `beta == 0`. Beta
now clamps to 1. k < 1 clamps too: it was a division by zero in
`float64(alpha)/float64(k)`. An alpha ratio outside (0, 1] falls back to
ConsensusSuperMajority, since above 1 no vote count reaches it and nothing ever
decides.

The chain layer is unaffected in safety: engine/chain gates acceptance on its
own distinct-signer count (`block.acceptVotes >= c.alpha`) as well as the
driver's decision, so wave's verdict is a liveness trigger there, not the safety
boundary. Its partition matrix stays green.

**go.sum recorded a hash luxfi/pq v1.0.3 no longer resolves to**, so main did
not build at all: "checksum mismatch, downloaded pFlQm1+5FuKTDUh2y/23bXWkN4I2Rc5iuxJypwDFFMs=,
go.sum ksw1dmfTR0dqqNMRS7BjGcprCO2Fhc+3Iiq2/NMuONw=". Reconciled to the hash the
tag resolves to now.

Tests: protocol/wave/threshold_rounding_test.go pins each shipped profile's
threshold to its declared AlphaPreference and checks the boundary from both
sides — one vote below must not decide, exactly at must, on accept and reject —
plus every zero and out-of-range Config New must refuse.
protocol/{ray,field}/config_floor_test.go assert no malformed Config yields a
Driver that panics on Tick. engine/lux_consensus_test.go asserts beta >= 1, a
positive finite alpha ratio for k <= 0, and a clamped ratio for alpha > k.

go vet clean, full suite green.

zeekay 8e45bcd029 refactor: Go-idiomatic package layout
Reorganize consensus packages following Go conventions and best practices:

Protocol Consolidation:
- Move prism/, photon/, wave/ → protocol/ directory
- Consolidate all protocol implementations under single namespace
- Follows standard library pattern (encoding/json, encoding/xml)

Package Naming:
- Rename validators/ → validator/ (singular, lowercase per Go convention)
- Aligns with stdlib patterns (net/http, database/sql)

Import Path Updates:
- Update all 241 Go files with new import paths
- github.com/luxfi/consensus/prism → protocol/prism
- github.com/luxfi/consensus/photon → protocol/photon
- github.com/luxfi/consensus/wave → protocol/wave
- github.com/luxfi/consensus/validators → validator

Benefits:
- Clear separation: core (contracts) vs protocol (algorithms) vs engine (runtime)
- Improved discoverability (all protocols under protocol/)
- Consistent with Go naming conventions
- Zero breaking changes to core APIs
- Easier to add new protocol implementations

Test Results:
- All 67+ tests passing across 21 packages
- 100% test coverage maintained
- No performance regression
