fix(fees): align Studio with Consensus v0.6 economics - #1748
Merged
Conversation
Mirror cap-priced round quotes, configured ladder semantics, appeal profit reserves, exact 2.5x rewards, typed appeal funding, immutable top-up schedules, live appeal overlay pricing, latest appeal ABIs, decision guards, and surplus refunds. Expose the canonical quote over RPC so cross-stack tests no longer maintain a second Studio formula.
Contributor
📝 WalkthroughWalkthroughThis change aligns Studio with updated protocol transaction flow. It adds fee-aware and lifecycle RPC handling, durable queue ordering, EVM envelope tracking, appeal decision metadata, salted GhostFactory address support, internal-message replay handling, new simulator fee helpers, and matching contract, worker, database, configuration, and UI updates. ChangesProtocol v0.6 lifecycle, ordering, and fee handling
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR changes public transaction admission and fee settlement, but the current implementation can accept an unverified sender identity, which may misattribute transactions and fees; related deployment and recovery paths also contain concrete failure cases. Merge should be blocked until the sender authorization and material runtime/deployment issues are addressed. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

The branch's pin replaced a dead source ref; v0.123-dev has since moved to feat/leader-data-to-genvm:201dc510c together with its vendored leader public data codec (#1747), so the base side is the one the vendored code expects.
The pin inherited from v0.123-dev references the pre-merge feature branch feat/leader-data-to-genvm, whose branch was deleted after squash-merge; the commit is unreachable from any ref, so the source build's clone cannot read it (fatal: unable to read tree). The same work is v0.6-dev head 3c96be6de (feat(manager): carry opaque leader public data, #29), which also contains the previous pin d07f21da. v0.123-dev itself needs the same repin.

Inline comments:
In @.env.example:
- Around line 95-97: Update the Hardhat test around provider initialization and
is_connected() to return or skip immediately when HARDHAT_URL is empty, before
creating the provider, while preserving the existing connectivity check when a
URL is configured.
In `@backend/consensus/worker.py`:
- Around line 334-340: Update _try_claim_work so the finalization-claim path for
repair-eligible transactions also checks _is_in_backoff before claiming,
matching the existing appeal-claim gate. Preserve the existing claim behavior
when the backoff has expired and prevent run() from immediately retrying rows
whose repair attempt was released.
- Around line 456-459: The blocked-descendant check in the appeal query must
ignore stale leases belonging to terminal FINALIZED or CANCELED transactions
while preserving overlap protection for active leases. Update the guard around
the transactions subquery and the corresponding recovery logic near
release_transaction so terminal leases are either bounded by lease staleness or
cleared during recovery.
In `@backend/database_handler/accounts_manager.py`:
- Around line 300-301: Update the refund guard in abort_tx_appeal_admission_once
so rollback and appeal-recovery cleanup are persisted whenever a bond was
removed, including zero-value bonds; only perform the recipient credit when
refund is greater than zero, while retaining the existing early return for
missing recipients.
In
`@backend/database_handler/migration/versions/e4f6a8c0d2b4_add_evm_envelope_ledger.py`:
- Line 64: Update the DISTINCT ON ordering in the migration query to sort
created_at descending with NULLS LAST, preserving the existing ordering by
lower(from_address), nonce, and hash so dated envelope rows are selected ahead
of NULL timestamps.
In `@backend/database_handler/transactions_processor.py`:
- Around line 109-112: Normalize nullable nonce values to 0 before passing them
as the uint256 argument in get_validator_vote_hash, matching the existing
behavior in _process_execution_hash and preserving valid non-null nonce values.
In `@backend/node/genvm/base.py`:
- Line 386: Guard allocation_subtree before child-fee traversal so string values
returned by _emission_allocation_subtree, including the "0x…" undecodable-byte
representation, are preserved for hashing but excluded from list-only
processing. Update the flow around create_child_fee_accounting and
_child_allocations_from_message_subtree to invoke allocation traversal only for
list-shaped subtrees, preventing string characters from reaching
_serializable_message_allocation.
In `@backend/protocol_rpc/endpoints.py`:
- Around line 2087-2157: Extract the duplicated appeal eligibility and
validator-count logic into one shared helper, returning the eligibility result,
validator_count, available_appeal_validators, normal_leader_count, and
leader_timeout_live_seats. Replace the corresponding logic in
estimate_latest_appeal_charge and _handle_appeal_or_top_up_and_submit with calls
to this helper, preserving all status, deadline, fee-accounting,
pool-resolution, validator-bound, and leader-timeout checks identically.
In `@backend/protocol_rpc/ghost_factory.py`:
- Line 63: Update the configuration flow around from_env() and address_for() so
GENLAYER_STUDIO_CREATION_PHASE_ADDRESS either actively overrides the returned
creation-phase address in address_for(), preserving the documented deployment
behavior, or remove the unused creation_phase_address parsing and constructor
field entirely.
In `@backend/protocol_rpc/types.py`:
- Around line 45-47: Update DecodedFinalizeTransactionDataArgs.tx_id to match
the ABI-decoded bytes supplied by TransactionParser, either by changing its type
annotation to bytes or normalizing the value before model construction; keep
expected_decision_id and the existing protocol payload behavior unchanged.
In `@backend/rollup/consensus_service.py`:
- Around line 281-286: Update the return annotation of the transaction method
containing the parameters transaction, from_address, retry, and calldata to
match its existing behavior: annotate it as dict[str, Any] | None because it
returns event details or None. Ensure Any is imported or already available,
without changing the runtime return behavior.
In `@frontend/src/components/Simulator/TransactionItem.vue`:
- Around line 534-535: Align the default value of
finalityWindowAppealFailedReduction with the backend by changing its frontend
default from 0.2 to 0. Keep the existing legacy deadline calculation and
configured environment-variable behavior unchanged.
In `@hardhat/contracts/v2_contracts/ConsensusMain.sol`:
- Around line 374-377: Add an overflow check before computing
txCalldataLengthOffset in the fee-aware transaction decoding flow: validate that
txCalldataOffset is no greater than type(uint256).max minus tupleStart, and
revert with InvalidFeeAwareTransactionEncoding when it would overflow. Keep the
existing bounds and alignment checks and only perform the addition after this
guard.
In `@tests/integration/conftest.py`:
- Line 44: Update the fee-default logic around the kwargs checks to distinguish
an omitted fees argument from an explicit fees=None; use key-presence checks at
both affected locations so defaults are injected only when "fees" is absent,
preserving intentional gasless calls.
- Line 33: Add complete type hints to the changed Python test functions:
annotate use_fee_aware_sdk_defaults and the wrapper functions in
tests/integration/conftest.py at lines 33, 43, and 51; annotate client with a
concrete mapping type in tests/load/test_state_integrity.py:60; add None return
annotations to the functions at
tests/db-sqlalchemy/test_health_orphan_detection.py:711, 748, and 785; and
annotate the listed test functions in tests/unit/test_simulator_sessions.py at
lines 20, 37, 471, 498, 541, 586, 657, 713, 767, 825, and 887, including
monkeypatch parameter types where requested.
Apply the same fix in `@backend/rollup/default_contracts/consensus_main.py` at
line 1541: Covered by the missing return annotation on the changed helper.
Apply the same fix in `@tests/unit/test_transactions_parser.py` at line 39:
Covered by the missing annotations across the new parser tests and helpers.
Apply the same fix in `@tests/unit/consensus/test_decisions_accepted.py` at line
468: Covered by the missing return annotations across the changed consensus
tests.
Apply the same fix in `@tests/unit/test_ghost_factory.py` at line 9: Covered by
the missing fixture, parameter, and return annotations in the listed test
helpers.
In `@third_party/genvm/version`:
- Line 1: Update the default GENVM configuration so the source pin from
third_party/genvm/version is supplied as GENVM_REF when no environment override
is set, ensuring docker-compose.yml and docker/Dockerfile.backend select source
mode and download_genvm.sh accepts the reference.

Treat GenVM v0.3 bucket 0 as the shared execution reservoir, bucket 1 as message fees, and buckets 2/3 as byte counters. Reconstruct the exact GenVM receipt meter to derive Consensus storage/event-write fees, and size recommendations for both chargeable execution and the enforced shared reservoir.

Cover the two topology boundaries behind validator appeals: a five-validator pool is exhausted by the initial committee, while twelve identities provide the full fresh seven-seat first jury and preserve the exact Consensus quote.
gltest owns separate fee argument adapters for deploys and writes. Bridge both so their public None defaults are treated as omitted by the fee-aware integration fixture, while explicit direct SDK fees=None stays gasless. Add a dependency-free regression covering both entry points.

Consensus is authoritative for deployed runtime behavior. The simulator independently checks economics; TLA+ and the written protocol specification supply lifecycle, input-domain, appeal-window, and appeal-selection invariants.
Problem and outcome
Studio had formula, lifecycle, authority, submission, and failure-recovery differences from the Consensus v0.6 train. This PR aligns implemented Studio behavior—not only displayed quotes—with current Consensus economics and closes applicable defects from the Consensus handoff campaign.
The result covers submission, activation, top-up, appeal, execution, settlement, cancellation, expiry, exact committee and rotation ladders, timeout and decision-bound lifecycle, message allocation and replay, contribution ownership and refunds, storage and receipt pricing, funding overlays, and failure recovery.
The leader-timeout appeal bond deliberately retains the configured source-round committee cost. For five validators it is
100 + 5 × 200 = 1,100; removing the timed-out leader changes replay membership, not the independent source-round cost used by the bond quote.Important implementation details
Undeterminedoutcome as Consensus.gen_getTransactionLifecycleandgen_estimateLatestAppealChargeRPCs.status: 0failure semantics and expose the local revert reason as additive receipt metadata. Envelope-only lifecycle calls are also returned byeth_getTransactionByHash, which lets standard viem receipt polling reach the durable receipt.

All 151 unique non-governance findings and controls in the consolidated Consensus handoff #1492 were inspected, including the cross-repository boundary controls from #1527 and #1528. Applicable fee, lifecycle, queue, appeal, message, and identity behavior is implemented and regression-covered. Solidity-only governance, staking, proxy-upgrade, EVM gas-bound pagination, and fixed-width arithmetic findings were classified as non-applicable to Studio rather than copied mechanically.
The Studio release-readiness audit additionally absorbed the applicable fixes from #1735, #1736, #1737, and #1746: zero-stake selection now raises the consensus-domain error, RNG construction is per call, native balance transfers use atomic SQL mutations, and method-call decoding handles complete RLP headers plus both leader-only values. Shared VRF constants and errors were separated to remove the circular import present in the source proposals. The valid error-disclosure half of #1739 is also included: unexpected exceptions are logged server-side and return only a stable generic JSON-RPC error. Wildcard CORS without credentials remains intentional for a public RPC used by arbitrary browser dapps; the proposed mandatory allowlist would break that supported surface.
The final audit added three forward-correctness fixes:
Those three Consensus PRs are expected-red handoffs and are not production fixes in #1526. Studio therefore implements the specified optimal behavior ahead of the currently deployed Solidity path for those cases; this is explicit forward correctness, not an accidental parity claim.
The release-review hardening pass also closes every verified behavioral finding: finalization repair obeys retry backoff; stale terminal leases cannot strand later work; zero-value appeal aborts persist rollback; nullable legacy nonces hash as zero; raw encoded allocation subtrees remain hashable but are not traversed; quote and admission share one appeal-eligibility computation; legacy envelope migration prefers dated rows; explicit integration

Studio currently pins immutable SDK commits so the prerelease can be qualified before coordinated package publication. Replace those pins with coordinated prerelease versions only when they contain these exact behaviors.
The default Studio Docker build now interprets the immutable
branch:commitbinding inthird_party/genvm/versionas source mode. Train images must prepare the sandboxed runner closure for exact source3c96be6defe30fd9843d47bedc0c66bec324d0fa, or explicitly select a separately qualified release withGENVM_TAG.Automatic allocation discovery is exact for root messages observed in the representative execution. Descendant allocations still require a manually supplied nested allocation tree when a caller needs to reserve those budgets explicitly; this is a documented capability boundary, not a formula mismatch.
Highest-risk surfaces are persisted fee accounting, asynchronous recovery, decision identity, and message replay. Rollback is the Studio commit stack on this PR; no external migration has been applied by publishing the branch.
