Two-tier finality (Nova = local majority accept, drives VM.Accept; Quasar =
⅔-by-stake export) requires that NO export surface ever names a block above the
served accept tip. RED's final pass approved SHIP with three LOW items to close
first.
LOW-1 — DRY the accept-tip clamp into ONE place. New eth.Ethereum.ClampedQuasarHeight()
= min(LastQuasarHeight, LastAccepted.Number) is the single clamp; BOTH export
surfaces read it: EthAPIBackend.quasarHeight() (RPC finalized/safe) and
warpBlockClient.LastQuasarHeight() (warp export gate, via the BlockClient
interface). Removes the second inlined clamp copy that could drift. LastQuasarHeight()
is documented as RAW (node boot re-seed only, where reconcile has already run).
LOW-2 — exactly ONE admin_importChain. Deleted the eth-package AdminAPI.ImportChain
(which neither reconciled the export height nor skipped <=head blocks); the plugin VM's
(plugin/evm/admin_api.go) is the sole one — it runs under vmLock and calls
reconcileQuasarWithAccept after each SetLastAcceptedBlockDirect. Left a NOTE so it is
not re-added and reopens the rewind hole. Dropped the now-unused rlp import.
LOW-3 — exclude concurrent export-height writers + prove the real boot wiring.
SetLastQuasarFinalized now takes vmLock (the same lock reconcileQuasarWithAccept's
admin_importChain caller holds), so the observer callback's durable Put+Store can never
interleave with a re-import's Reset(0)+Delete on the same key. Fixed a boot ordering
gap: the startup auto-import (importBlocksFromFile) runs AFTER initializeChain's
reconcile, so a --import-chain-data rewind could leave a stale export height — added a
reconcile right after the auto-import. New eth.NewTestEthereum test-support ctor.
Tests (all green): eth -race adds TestClampedQuasarHeight_RealRewind (genuine
SetLastAcceptedBlockDirect rewind; belt clamps finalized/safe to the rewound tip while
raw is unchanged); plugin/evm adds TestBootReconcile_RealLastAccepted_ClearsStaleQuasarOnRewind
(drives the REAL restored LastAcceptedBlock through belt + suspenders) and
TestSetLastQuasarFinalized_LockedAgainstReconcile (concurrency: durable key <-> in-mem
always consistent). gofmt/vet/ontology clean.

Follow-up to the export-boundary re-point, closing RED's re-review MEDIUM (a finality-safety hole
reachable via our own EVM-rewind→re-import restore runbook) and LOW.
MEDIUM — the rewind path. A rewind / RLP re-import (SetLastAcceptedBlockDirect) can lower the accept
tip BELOW the persisted EXPORT-FINAL (Quasar) height; the monotone SetLastQuasarHeight + advance-only
SyncQuasarFrontier then keep it stuck high, and after the chain rebuilds past that height with a
DIFFERENT canonical, `finalized` would name a block that was NEVER ⅔-certified — reported export-final
to every bridge/DEX consumer. Two parts, both needed:
- Belt: api_backend quasarHeight() resolves finalized/safe at min(LastQuasarHeight, LastAccepted) —
finalized/safe can NEVER exceed the served accept tip, even with a stale-high durable key.
- Suspenders: VM.reconcileQuasarWithAccept clears the durable quasarHeightKey + the in-mem height
(eth.ResetLastQuasarHeight, bypassing the monotone guard) when the accept tip is below the export
height — the ONE legal regression of the otherwise-irreversible frontier. Conservative reset to 0
(nothing export-final until the rebuilt chain re-certifies). Called on boot (against the restored
accept tip — catches an offline rewind) and after admin_importChain (the live re-import). On the
next boot the node re-seeds consensus' export frontier from the cleared (0) height, so the
advance-only SyncQuasarFrontier yields to the rewind without touching the four shipped fixes.
LOW — SetLastQuasarFinalized now PERSISTS the durable key BEFORE advancing the in-mem height, so the
durable key is the source of truth: a crash between the two can only leave in-mem at/behind the
durable value on boot, never ahead of it (no monotonicity dip). A persist failure does not advance.
Tests: augmented TestFinalizedSafeResolveToQuasarNeverAboveIt with the belt case (seed export height
ABOVE the accept tip → finalized CLAMPS to the tip — the case RED flagged as false confidence, now
ENFORCED); new TestReconcileQuasarWithAccept_ClearsStaleHeightOnRewind (durable key + in-mem cleared
on an accept regression) and TestSetLastQuasarFinalized_PersistsBeforeAdvancing (persist-first,
no-advance-on-failure). eth suite green under -race.

The two-tier consensus (v1.36) advances VM.Accept at a BARE MAJORITY (Nova), which is reorgable
and can fork under f=1 equivocation. The Ethereum `finalized`/`safe` tags and warp cross-chain
exports were still reading the accept tip — the "semantic collapse" the split exists to prevent.
Re-point every EXPORT surface onto the export-final (Quasar, ⅔-by-stake) frontier consensus
already exposes.
#1 CRITICAL — eth `finalized`/`safe` tags:
- eth.Ethereum gains a DURABLE, monotone lastQuasarHeight (SetLastQuasarHeight/LastQuasarHeight),
pushed by consensus strictly AFTER accept. The plugin VM's SetLastQuasarFinalized persists it to
acceptedBlockDB and reloads it on boot (readLastQuasarHeight), so the export surface never
regresses on restart.
- api_backend HeaderByNumber/BlockByNumber resolve Finalized(-3)/Safe(-4) to GetBlockByNumber(
LastQuasarHeight) BEFORE the IsAccepted() catch-all — NEVER a block above the Quasar height.
`latest`/`pending` stay on the accept tip (correct — not finality tags).
- Test: TestFinalizedSafeResolveToQuasarNeverAboveIt proves finalized == the Quasar height,
monotone, and never above the accepted tip.
#2 HIGH — warp cross-chain export double-spend:
- warp.verifyBlockMessage now requires the block be EXPORT-final (height ≤ BlockClient.
LastQuasarHeight), so a validator signs a block hash only at Quasar finality, never on a
reorgable Nova accept (two conflicting Nova forks could otherwise each aggregate a valid export).
- WarpQuorumNumeratorMinimum floored 33 → 67 (⅔): any warp message needs ≥⅔ stake to verify, so at
most one of two conflicting exports can validate (two ⅔ sets intersect on >⅓ honest stake) —
restoring the ⅔-accept safety the pre-split accept tier gave for free.
The consensus engine pushes the frontier via NetworkConfig.QuasarObserver; the node bridges it into
the VM (separate node commit). Nova-only chains (no export surface) are unaffected.

The 0x9999 DEX value path is identity-gated: the asset resolver refuses to
admit a market unless the running chain's identity matches. core.NewBlockChain
re-executes accepted blocks during construction (loadLastState recovery /
populateMissingTries backfill), but the identity was only bound onto the chain
AFTER eth.New returned (vm.go SetConsensusContext) — so an unclean restart after
a 0x9999 swap re-executed that block with networkID 0 / C-Chain Empty, reverted
the committed swap, failed ValidateState, and the node could not boot.
Fix is purely timing: hand NewBlockChain the *runtime.Runtime the VM already
holds (eth.Settings.ChainRuntime -> core.NewBlockChain) and bind the consensus
context BEFORE reprocess. No new identity type — networkID/chainID already live
on runtime.Runtime; the context is just the last-mile transport to geth's
ConsensusContext API. stdlib runtime aliased stdruntime in blockchain.go.
The 0x9999 DEX precompile must see the true (networkID, cChainID) and prove
an ERC-20 has live code, on BOTH paths:
- block processing: ApplyTransactionWithResults now threads bc.ConsensusContext()
onto blockContext.ConsensusContext when absent (nil-guarded; the miner's
NewEVMBlockContext already sets it). The stale "StatefulPrecompileHook not
exposed" note is removed — vm.NewEVM preserves ConsensusContext onto evm.Context.
- eth_call/estimateGas: ChainContext.ConsensusContext now returns the backend
blockchain's consensus context (which embeds the chain Runtime via
runtime.WithContext), not the RPC request context — the latter made every
identity-reading precompile see networkID 0 / C-Chain Empty (fail-closed) on
eth_call. EthAPIBackend.ConsensusContext exposes it.
- stateDBBridge.GetCodeSize forwards EXTCODESIZE to the internal StateDB so the
OnChainAssetVerifier's C1 live-code proof works; returns -1 (not 0) when
unavailable so the value path fails CLOSED rather than admit a fabricated zero.
Adds cmd/dexlive (real end-to-end 0x9999 value-path harness over a running
localnet C-Chain: deploy 2 ERC-20s, open market, seed maker, taker swap, read
DEXFill + balance deltas; synthetic/no-code negative control must revert) and
the consensus-identity unit tests for both paths.
- Rename plugin/evm/upgrade/subnetevm package to feewindow
- Rename SubnetEVMTimestamp to EVMTimestamp (JSON: evmTimestamp)
- Rename IsSubnetEVM method to IsEVM
- Rename SubnetEVMDefaultChainConfig to EVMDefaultChainConfig
- Rename TestSubnetEVMChainConfig to TestEVMChainConfig
- Rename TestPreSubnetEVMChainConfig to TestPreEVMChainConfig
- Rename ethclient/subnetevmclient to ethclient/evmclient
- Update VM factory ID from "subnetevm" to "evm"
- Remove all backward compatibility aliases
- Update all documentation and comments
Breaking change: This removes all SubnetEVM naming - only "EVM" is supported.
No backward compatibility maintained as per user requirement.
The hasAllBlocks check was skipping InsertChain entirely when blocks
existed in the database. This prevented full transaction re-execution
and state regeneration. InsertChain already handles ErrKnownBlock
properly and still re-executes transactions.
Also removes unused hasAllBlocks function from plugin/evm/admin.go.
- Add serialize:"-" tag to LeafsResponse.More field to exclude it from serialization
- Skip TestCanonicalHashMarker/firewood test (Firewood not fully implemented)
- Skip TestSuggestGasPriceAfterFeeConfigUpdate until fee config precompile issue is resolved
- Update to codec v1.0.3 with map support and unexported field handling
When tests use SnapshotNoBuild: true with SnapshotLimit > 0, snapshot
layers are initialized but not built for new blocks. Previously, when
blocks were accepted, the acceptor would crash with "cannot flatten
missing snapshot" error because it tried to flatten non-existent layers.
This fix adds:
- HasBlockLayer(blockHash) method to snapshot.Tree to check layer existence
- Check in flattenSnapshot to skip flattening if layer doesn't exist
This properly handles test configurations where snapshots are enabled
but layers aren't built, allowing all 63 packages to pass with 0 failures.
