…gas (#191) * fix: close reth 2.5.2 upgrade gaps in engine validator and intrinsic gas Follow-ups to the v2.4.0 -> v2.5.2 upgrade, found while auditing that diff against the upstream sources. Forward `EngineValidator::on_canonical_head_changed`. reth 2.5.0 added this method with an empty default body, so `MorphTreeEngineValidator` — a wrapper that must delegate every method to `inner` — silently replaced `BasicEngineValidator`'s implementation (txpool prewarming, opt-in via `--engine.txpool-prewarming`) with the no-op default instead of failing to compile. Document that forwarding contract on the type so the next upgrade re-checks it: a method with a default body is exactly the case the compiler cannot catch. Derive the EIP-2780 intrinsic-gas info in `validate_initial_tx_gas` from `Cfg::is_amsterdam_eip2780_enabled()` the way revm's own handler does, instead of hardcoding the new `None` argument. `CfgEnv::with_spec_and_mainnet_gas_params` (used by `MorphEvmConfig`) derives that flag from the spec, so a hardcoded `None` would silently diverge from upstream intrinsic gas if a Morph hardfork ever mapped to AMSTERDAM. Behaviour is unchanged today: every Morph hardfork maps below AMSTERDAM. Extend `test_morph_hardforks_do_not_enable_amsterdam_state_gas` to assert the EIP-2780 flag stays off for every Morph hardfork, with a positive control at AMSTERDAM so the guard cannot become vacuous if the flag stops being spec-derived. Restore the intent of `test_eip7702_refund_stays_regular_for_morph_specs`. revm 42 removed `tx_eip7702_state_refund` / `tx_eip7702_auth_refund`, so the test had been reduced to a duplicate of the state-gas assertion above it while keeping a message about refunds, plus a hardcoded 12500. It now asserts the surviving equivalent — the full per-auth refund equals `PER_EMPTY_ACCOUNT_COST - PER_AUTH_BASE_COST` — against revm's constants. Drop `reth-trie-db`: it lost its last use when the `ChangesetCache` parameter was replaced by `OverlayManager`. Also record why `evm_call` hands a fresh journal checkpoint to `Handler::execution` and why its `None` arm is unreachable for Morph. * refactor(revm): drop custom SLOAD/SSTORE overrides in favour of native instructions (#194) `sload_morph` and `sstore_morph` existed to undo an `original_value` clobber in revm, not to express any Morph rule. `sstore_morph` in particular re-implemented the whole upstream SSTORE lifecycle — static-call check, reentrancy sentry, Berlin cold loading, dynamic gas and refund accounting — to insert one repair in the middle of it. Why they were needed: token fee deduction leaves the caller's fee-token slot with the DB-committed `original_value`, the fee-deducted `present_value` and `is_cold = true`. That is the same triple morph-geth has, where the EIP-2200 committed value (`GetCommittedState`) and the EIP-2929 access list are independent. revm <= 41 conflated them in `EvmStorageSlot::mark_warm_with_transaction_id`, re-baselining `original_value = present_value` whenever a slot was cold — including a slot marked cold within the same transaction. EIP-2200 then saw a clean slot and charged `SSTORE_RESET` (2900) instead of the dirty-slot 100, diverging from morph-geth by 2800 gas per write. Why they are no longer needed: bluealloy/revm#3746 (released in revm-state 42.0.0, still present in 43) keys that re-baseline on the transaction boundary instead of on the cold flag, so the committed value survives an explicit `mark_cold()`. The native instructions now produce geth-equivalent gas on their own. Verified as a controlled comparison against the golden e2e test: revm 41 + overrides 48_128 (previous state) revm 41 - overrides 50_928 (+2800: the divergence these overrides hid) revm 42 - overrides 48_128 (this commit) The middle row also confirms `morph_tx_v0_token_fee_transfer_to_fee_token_contract_gas_regression` is a real tripwire rather than a permanently green assertion, so it is left untouched as the gate for this change. Removing the copies also retires three drifts that had already accumulated in them: - the EIP-8037 branch of upstream `sstore_default_gas_accounting` (`state_gas!` plus `refill_reservoir`) was never mirrored; dormant only because every Morph hardfork maps below AMSTERDAM. - the SSTORE cold-load skip threshold stayed at revm 41's `cold_storage_additional_cost()` (2000) after upstream 42 moved it to `cold_storage_cost()` (2100); unreachable because the Istanbul reentrancy sentry already requires `remaining > call_stipend` (2300). - the `original_value` repair ran for every cold slot, including slots of an account created within the same transaction, where revm reports `ZERO` while the DB may still hold residual storage. `blockhash_morph` (0x40) and the disabled SELFDESTRUCT / BLOBHASH / BLOBBASEFEE opcodes stay: those are genuine Morph semantics, unrelated to revm's version. Closes #187
Exercise Emerald and Jade with normal and tight gas limits. Assert block and receipt gas, transfer logs, balances, and exact token fee settlement. The access-list case fails on the PR base with 53,228 gas instead of 50,428.

LGTM. Reviewed every Morph-specific adaptation against upstream reth v2.5.2 and revm 42.0.1 sources; CI is fully green (Build, Clippy, Run/Doc/E2E Tests, cargo-deny all pass).
Key invariants verified intact:
- EngineValidator wrapper: all 7 v2.5.2 trait methods forwarded — critically
on_canonical_head_changed(new 2.5.0 default-body method) is explicitly delegated, not silently defaulted, so txpool prewarming isn't disabled.payload_builder_resourcescorrectly replacescache_for/payload_state_root_handle_for. - L1 zero-refund:
post_execution::refundnon-L1 path is byte-identical to upstream default; L1-message branch keepsset_refund(0). - eip7702/GasTracker:
validate_initial_tx_gasreproduces upstream's eip2780 derivation while keeping the L1-message intrinsic-gas fallback. - MorphStateRootStrategy: added provider bounds exactly match
DefaultStateRootStrategy; pre-Jade trusted-root behavior preserved. - convert_log: identity
Ok(log)correct (no RPC-layer log transform). - Removal of custom sload/sstore opcodes: correct — revm-state 42.0.0
mark_warm_with_transaction_idnow re-baselines original_value only on tx-id mismatch (bluealloy/revm#3746), making the hand-written opcodes redundant. The 2800-gas tripwire test is kept and a new access-list gas regression test added (50,428 gas, arithmetic checked).
Clean migration — no leftover references to removed APIs. Nit: apply_eip7702_auth_list uses evm.ctx() where upstream uses ctx_mut(); both compile, cosmetic.
