From 2e3570ed34e5227cad78383dfb7ac5bd19cdcf25 Mon Sep 17 00:00:00 2001 From: maclane Date: Fri, 7 Aug 2026 16:32:07 -0400 Subject: [PATCH 001/101] feat(tbtc): UTXO reservation wallet-side foundations Companion of the tbtc-v2 UTXO reservation draft (threshold-network/ tbtc-v2#1088). A reservation is a deposit the wallet anchors -- spends in a 1-input-1-output transaction into a fresh wallet-controlled output with no refund path -- instead of sweeping, so the reserved coins never commingle with the pooled supply and are redeemable in-kind. Adds the wallet-side foundations: - wallet action types for the four reservation lifecycle actions (anchor, reserved redemption, re-anchor, dissolution), appended after the existing enum values to preserve serialized compatibility, - coordination proposal types with marshaling and factory registration (JSON-based for now; switching to protobuf once the reservation message types are added to the coordination proto definition), - Chain interface extensions for reading reservations and parameters and validating the four proposal kinds via WalletProposalValidator, - unsigned transaction assembly for all four lifecycle shapes, enforcing the 1-input-1-output lineage (dissolution additionally spends the wallet main UTXO as its second input, per the Bridge rules), - tests for action parsing, proposal marshaling roundtrips, and assembler input validation. The Ethereum chain implementation stubs the new interface methods with descriptive errors: the contract bindings can only be regenerated once the reservation Bridge API is published with the @keep-network/tbtc-v2 package. Coordination executor wiring and tbtcpg proposal generation follow in the same step. --- pkg/chain/ethereum/tbtc.go | 80 +++++++ pkg/tbtc/chain.go | 44 ++++ pkg/tbtc/chain_test.go | 42 ++++ pkg/tbtc/marshaling.go | 16 +- pkg/tbtc/reservation.go | 440 +++++++++++++++++++++++++++++++++++ pkg/tbtc/reservation_test.go | 141 +++++++++++ pkg/tbtc/wallet.go | 20 ++ pkg/tbtc/wallet_test.go | 20 +- 8 files changed, 795 insertions(+), 8 deletions(-) create mode 100644 pkg/tbtc/reservation.go create mode 100644 pkg/tbtc/reservation_test.go diff --git a/pkg/chain/ethereum/tbtc.go b/pkg/chain/ethereum/tbtc.go index 50e42be20e..cf84de27b1 100644 --- a/pkg/chain/ethereum/tbtc.go +++ b/pkg/chain/ethereum/tbtc.go @@ -2408,3 +2408,83 @@ func (tc *TbtcChain) GetRedemptionDelay( func (tc *TbtcChain) GetDepositMinAge() (uint32, error) { return tc.walletProposalValidator.DEPOSITMINAGE() } + +// GetReservation is not yet supported by the Ethereum chain implementation: +// the reservation contract bindings will be regenerated once the reservation +// Bridge API is published with the @keep-network/tbtc-v2 package. +func (tc *TbtcChain) GetReservation( + reservationKey *big.Int, +) (*tbtc.Reservation, error) { + return nil, fmt.Errorf( + "reservations not supported yet by the Ethereum chain implementation", + ) +} + +// ReservationParameters is not yet supported by the Ethereum chain +// implementation: the reservation contract bindings will be regenerated once +// the reservation Bridge API is published with the @keep-network/tbtc-v2 +// package. +func (tc *TbtcChain) ReservationParameters() ( + *tbtc.ReservationParameters, + error, +) { + return nil, fmt.Errorf( + "reservations not supported yet by the Ethereum chain implementation", + ) +} + +// ValidateReservationAnchorProposal is not yet supported by the Ethereum +// chain implementation: the reservation contract bindings will be +// regenerated once the reservation Bridge API is published with the +// @keep-network/tbtc-v2 package. +func (tc *TbtcChain) ValidateReservationAnchorProposal( + walletPublicKeyHash [20]byte, + proposal *tbtc.ReservationAnchorProposal, + depositExtraInfo struct { + *tbtc.Deposit + FundingTx *bitcoin.Transaction + }, +) error { + return fmt.Errorf( + "reservations not supported yet by the Ethereum chain implementation", + ) +} + +// ValidateReservedRedemptionProposal is not yet supported by the Ethereum +// chain implementation: the reservation contract bindings will be +// regenerated once the reservation Bridge API is published with the +// @keep-network/tbtc-v2 package. +func (tc *TbtcChain) ValidateReservedRedemptionProposal( + walletPublicKeyHash [20]byte, + proposal *tbtc.ReservedRedemptionProposal, +) error { + return fmt.Errorf( + "reservations not supported yet by the Ethereum chain implementation", + ) +} + +// ValidateReservationReanchorProposal is not yet supported by the Ethereum +// chain implementation: the reservation contract bindings will be +// regenerated once the reservation Bridge API is published with the +// @keep-network/tbtc-v2 package. +func (tc *TbtcChain) ValidateReservationReanchorProposal( + sourceWalletPublicKeyHash [20]byte, + proposal *tbtc.ReservationReanchorProposal, +) error { + return fmt.Errorf( + "reservations not supported yet by the Ethereum chain implementation", + ) +} + +// ValidateReservationDissolutionProposal is not yet supported by the +// Ethereum chain implementation: the reservation contract bindings will be +// regenerated once the reservation Bridge API is published with the +// @keep-network/tbtc-v2 package. +func (tc *TbtcChain) ValidateReservationDissolutionProposal( + walletPublicKeyHash [20]byte, + proposal *tbtc.ReservationDissolutionProposal, +) error { + return fmt.Errorf( + "reservations not supported yet by the Ethereum chain implementation", + ) +} diff --git a/pkg/tbtc/chain.go b/pkg/tbtc/chain.go index a58599f273..1bf1fbf2de 100644 --- a/pkg/tbtc/chain.go +++ b/pkg/tbtc/chain.go @@ -427,6 +427,50 @@ type WalletProposalValidatorChain interface { }, ) error + // GetReservation gets the on-chain reservation record for the given + // reservation key.

The new abi/Bridge.go surface carries the reservation selectors exposed on the Bridge itself -- isReservedDeposit, setReservationRouter, and getReservationRouter -- in addition to the existing Bridge API; the regenerated MaintainerProxy, WalletProposalValidator, RedemptionWatchtower, and Relay bindings reflect minor ABI surface additions that landed in the same bridge-integration commit. The abi/ReservationRouter.go binding is the encoding source for the six read/validate methods filled in on the next commit; its call site is the Bridge address (Bridge.fallback routes the router selector via delegatecall), so all reads, writes, and event/log filters must target the Bridge address, not the router's own deployment address. --- pkg/chain/ethereum/tbtc/gen/Makefile | 28 +- .../tbtc/gen/_address/ReservationRouter | 0 pkg/chain/ethereum/tbtc/gen/abi/Bridge.go | 614 +- pkg/chain/ethereum/tbtc/gen/abi/LightRelay.go | 5 +- .../tbtc/gen/abi/LightRelayMaintainerProxy.go | 5 +- .../ethereum/tbtc/gen/abi/MaintainerProxy.go | 5 +- .../tbtc/gen/abi/RedemptionWatchtower.go | 33 +- .../tbtc/gen/abi/ReservationRouter.go | 3270 +++++++++++ .../tbtc/gen/abi/WalletProposalValidator.go | 79 +- pkg/chain/ethereum/tbtc/gen/cmd/Bridge.go | 367 ++ .../tbtc/gen/cmd/RedemptionWatchtower.go | 35 + .../tbtc/gen/cmd/ReservationRouter.go | 1331 +++++ .../tbtc/gen/cmd/WalletProposalValidator.go | 88 + .../ethereum/tbtc/gen/contract/Bridge.go | 1257 +++- .../tbtc/gen/contract/RedemptionWatchtower.go | 37 + .../tbtc/gen/contract/ReservationRouter.go | 5187 +++++++++++++++++ .../gen/contract/WalletProposalValidator.go | 91 + 17 files changed, 12396 insertions(+), 36 deletions(-) create mode 100644 pkg/chain/ethereum/tbtc/gen/_address/ReservationRouter create mode 100644 pkg/chain/ethereum/tbtc/gen/abi/ReservationRouter.go create mode 100644 pkg/chain/ethereum/tbtc/gen/cmd/ReservationRouter.go create mode 100644 pkg/chain/ethereum/tbtc/gen/contract/ReservationRouter.go diff --git a/pkg/chain/ethereum/tbtc/gen/Makefile b/pkg/chain/ethereum/tbtc/gen/Makefile index 2229760f03..1bdbdea328 100644 --- a/pkg/chain/ethereum/tbtc/gen/Makefile +++ b/pkg/chain/ethereum/tbtc/gen/Makefile @@ -1,7 +1,7 @@ npm_package_name=@keep-network/tbtc-v2 # Contracts for which the bindings should be generated. -required_contracts := Bridge MaintainerProxy LightRelay LightRelayMaintainerProxy WalletProposalValidator RedemptionWatchtower +required_contracts := Bridge MaintainerProxy LightRelay LightRelayMaintainerProxy WalletProposalValidator RedemptionWatchtower ReservationRouter # There is a bug in the currently used abigen version (v1.10.19) that makes it # re-declaring structs used by multiple contracts @@ -22,6 +22,7 @@ define after_abi_hook $(eval type := $(1)) $(if $(filter $(type),WalletProposalValidator),$(call fix_wallet_proposal_validator_collision)) $(if $(filter $(type),MaintainerProxy),$(call fix_maintainer_proxy_collision)) + $(if $(filter $(type),ReservationRouter),$(call fix_reservation_router_collision)) endef define fix_wallet_proposal_validator_collision @perl -pi -e s,BitcoinTxInfo,BitcoinTxInfo2,g ./abi/WalletProposalValidator.go @@ -32,12 +33,26 @@ define fix_maintainer_proxy_collision @perl -pi -e s,BitcoinTxProof,BitcoinTxProof2,g ./abi/MaintainerProxy.go @perl -pi -e s,BitcoinTxInfo,BitcoinTxInfo3,g ./abi/MaintainerProxy.go endef +# ReservationRouter introduces its own copies of the BitcoinTx.* structs +# (BitcoinTxInfo, BitcoinTxProof, BitcoinTxUTXO) used by submitReservationProof. +# These names already collide with Bridge's (BitcoinTxInfo/BitcoinTxProof/BitcoinTxUTXO), +# WalletProposalValidator's (BitcoinTxInfo2/BitcoinTxUTXO3), and MaintainerProxy's +# (BitcoinTxInfo3/BitcoinTxProof2/BitcoinTxUTXO2).

reservation read/validate methods against real bindings Replaces the seven reservation read/validate stubs in tbtc.go (those declared today in pkg/tbtc/chain.go:430-480, previously returning "reservations not supported yet" errors) with real implementations backed by the regenerated abigen bindings. Three view reads (GetReservation, GetReservationAction, ReservationParameters) are reached through tc.reservationRouter, a new binding constructed against the Bridge address -- the router code only executes via Bridge.fallback's delegatecall, so binding the ReservationRouter ABI at the Bridge address is the only configuration that gives the operator a live read path (the deployed router address holds empty storage). Two on-chain proposal validators (ValidateReservationAnchorProposal, ValidateReservationReanchorProposal) are reached through the existing tc.walletProposalValidator handle against the regenerated WalletProposalValidatorReservation*Proposal ABI structs. Two further validators (ValidateReservedRedemptionProposal, ValidateReservationDissolutionProposal) remain unsupported on this milestone's bridge-integration surface -- the WalletProposalValidator contract does not expose those entry points -- so their bodies return an explicit "validator not exposed on the m1 bridge-integration surface" error. The chain.go interface declarations are satisfied so the package compiles; downstream tasks can replace these bodies once the missing validators land on the contract side. Thin field-by-field abigen-to-Go converters are added for the three view structs (convertReservationFromAbiType, convertReservationActionFromAbiType, convertReservationParametersFromAbiType), plus three small parsers (parseReservationState, parseReservationActionType, parseReservationActionState) that mirror the on-chain enum layouts. The reservationRouter field is constructed in newTbtcChain via the reservationRouterBinding helper, which makes the storage/address rationale explicit at the call site rather than burying it in the struct field comment. --- pkg/chain/ethereum/tbtc.go | 449 +++++++++++++++++++++++++++++++++---- 1 file changed, 408 insertions(+), 41 deletions(-) diff --git a/pkg/chain/ethereum/tbtc.go b/pkg/chain/ethereum/tbtc.go index 83c9629fef..e2835bc579 100644 --- a/pkg/chain/ethereum/tbtc.go +++ b/pkg/chain/ethereum/tbtc.go @@ -64,6 +64,17 @@ type TbtcChain struct { sortitionPool *ecdsacontract.EcdsaSortitionPool walletProposalValidator *tbtccontract.WalletProposalValidator redemptionWatchtower *tbtccontract.RedemptionWatchtower + // reservationRouter is the abigen binding for ReservationRouter.sol's ABI + // (functions, events, errors).

Submission pattern mirrors the existing SubmitRedemptionProofWithReimbursement flow: GasEstimate + 20% margin + ethutil.TransactionOptions. * Twelve additional read/view methods (ReservationCaps, WalletReservationsAmount, WalletReservationsCount, WalletReservations, ReservationByAnchorUtxo, ReservedDepositWallet, PendingReservedDeposits, Reservations, ReservationActions, ActiveReservationsCount, ReservationRouter, IsReservedDeposit), plus ReservationParametersFull as an alias of ReservationParameters. IsReservedDeposit and ReservationRouter read via the Bridge binding because they map to Bridge state. * New Go types ReservationRequest, ReservationActionRecord, BitcoinTxInfo, BitcoinTxProof, BitcoinTxUTXO mirror the on-chain ReservationRouter view structs verbatim. * Thirteen event subscriptions and twelve filter structs for every reservation event listed in the brief, filtering against the Bridge address (delegatecall preserves the caller's address context so router-emitted events carry the Bridge address). * localChain mocks for all of the above so the interface stays satisfiable by the test double. The reservationRouter binding remains bound to the Bridge address (invariant 3 of ReservationRouter.sol) - no second binding against the router's standalone address is constructed. --- pkg/chain/ethereum/tbtc.go | 1143 ++++++++++++++++++++++++++++++++++++ pkg/tbtc/chain.go | 517 +++++++++++++++- pkg/tbtc/chain_test.go | 225 +++++++ 3 files changed, 1882 insertions(+), 3 deletions(-) diff --git a/pkg/chain/ethereum/tbtc.go b/pkg/chain/ethereum/tbtc.go index e2835bc579..3aaf5a6d1d 100644 --- a/pkg/chain/ethereum/tbtc.go +++ b/pkg/chain/ethereum/tbtc.go @@ -2868,3 +2868,1146 @@ func parseReservationActionState(value uint8) (tbtc.ReservationActionState, erro return 0, fmt.Errorf("unexpected reservation action state value: [%d]", value) } } + +// RequestReservationAcceptance asks the Bridge (via its ReservationRouter +// delegatecall target) to start a new reservation acceptance action generation +// for the given reservation.

getUnprovenReservationReanchorTransactions discovers unproven re-anchor Bitcoin transactions by walking ReservationReanchorRequested events, skipping settled/timed-out action generations, and matching candidate transactions against the still-registered anchor outpoint via ReservationByAnchorUtxo. - reservationReanchorTransactionProofSubmitter re-derives the (reservationKey, requestNonce) pair the generic proof-loop signature cannot carry, then submits via the existing SubmitReservationReanchorProof path. Extends the spv.Chain interface with PastReservationReanchorRequestedEvents and ReservationByAnchorUtxo (already present on TbtcChain); adds matching localChain test fakes. Reservation acceptance proof submission remains a documented placeholder pending its own watcher integration - out of scope here. Covers the discovery precision paths (shape mismatch, anchor mismatch, settled-action skip) and the submitter's nonce/key derivation with new unit tests. --- pkg/maintainer/spv/chain.go | 16 + pkg/maintainer/spv/chain_test.go | 85 ++++- .../spv/reservation_reanchor_proof.go | 237 ++++++++++++ .../spv/reservation_reanchor_proof_test.go | 358 ++++++++++++++++++ pkg/maintainer/spv/spv.go | 57 +-- 5 files changed, 700 insertions(+), 53 deletions(-) diff --git a/pkg/maintainer/spv/chain.go b/pkg/maintainer/spv/chain.go index 71acc042de..31b4497e2a 100644 --- a/pkg/maintainer/spv/chain.go +++ b/pkg/maintainer/spv/chain.go @@ -206,4 +206,20 @@ type Chain interface { PastReservationActionTimedOutEvents( filter *tbtc.ReservationActionTimedOutEventFilter, ) ([]*tbtc.ReservationActionTimedOutEvent, error) + + // PastReservationReanchorRequestedEvents fetches past + // ReservationReanchorRequested events according to the provided filter + // or unfiltered if the filter is nil.

Each iteration walks each watched wallet's reservations (WalletReservations) and calls the existing CheckReservationActionTimeouts per reservation. A failure checking one wallet is logged and does not abort the iteration or stop the loop. - startActionTimeoutRun (reservation_wiring.go) now threads ctx into Run(ctx) instead of discarding it; context.Canceled is treated as the expected shutdown path, not a failure to log. Run's signature changes from Run() to Run(ctx context.Context); the only call site (startActionTimeoutRun) is updated. Wallet discovery (who calls WatchWallet with which wallets) remains a separate, pre-existing gap shared by all three reservation watchers - see the 'PR H placeholder' comments on subscribeReservationWalletClosed and subscribeReservationActionTimedOut - and is out of scope here. Covers WatchWallet dedup, all three Run precondition guards, and an end-to-end test that Run notifies a timed-out action on its first (immediate) iteration and returns promptly on ctx cancellation. --- .../spv/reservation_action_timeout_watch.go | 111 +++++++++++--- .../reservation_action_timeout_watch_test.go | 142 ++++++++++++++++++ pkg/maintainer/spv/reservation_wiring.go | 9 +- 3 files changed, 240 insertions(+), 22 deletions(-) diff --git a/pkg/maintainer/spv/reservation_action_timeout_watch.go b/pkg/maintainer/spv/reservation_action_timeout_watch.go index 270e7f8a3c..1b3fa2a34e 100644 --- a/pkg/maintainer/spv/reservation_action_timeout_watch.go +++ b/pkg/maintainer/spv/reservation_action_timeout_watch.go @@ -1,8 +1,10 @@ package spv import ( + "context" "fmt" "math/big" + "sync" "time" "github.com/keep-network/keep-core/pkg/tbtc" @@ -43,6 +45,9 @@ type ReservationActionTimeoutWatcher struct { // to look up operator addresses (the SPV maintainer chain interface // does not expose GetOperatorID today). membersResolver WalletMembersResolver + + walletsMutex sync.Mutex + watchedWallets map[[20]byte]struct{} } // WalletMembersResolver maps a wallet public key hash to the operator IDs @@ -117,6 +122,7 @@ func NewReservationActionTimeoutWatcher( nowFn: defaultActionTimeoutNowFn, interval: pollInterval, membersResolver: membersResolver, + watchedWallets: make(map[[20]byte]struct{}), } } @@ -126,24 +132,47 @@ func defaultActionTimeoutNowFn() uint32 { return uint32(time.Now().Unix()) } -// Run starts the background poll loop.

That field tracks the reservation's live action generation, which can have moved on since the discovered transaction was built - e.g. the original re-anchor action times out and a new, unrelated action generation becomes current while the SPV maintainer is still waiting out requiredConfirmations on the old transaction. Submitting the live nonce in that case pairs a stale, unrelated transaction with the wrong action generation. Fix: before submitting, fetch the action generation at the reservation's current nonce and require it to still be a Pending Reanchor action targeting the exact wallet the discovered transaction actually pays. Any mismatch is reported as an error so the proof loop treats the transaction as not-yet-submittable instead of silently misattributing the proof. Adds two regression tests: one for the action-no-longer-pending case, one for the pending-but-different-target-wallet case. --- .../spv/reservation_reanchor_proof.go | 61 ++++- .../spv/reservation_reanchor_proof_test.go | 241 +++++++++++++++++- 2 files changed, 292 insertions(+), 10 deletions(-) diff --git a/pkg/maintainer/spv/reservation_reanchor_proof.go b/pkg/maintainer/spv/reservation_reanchor_proof.go index 5353b05707..c6bd4035e1 100644 --- a/pkg/maintainer/spv/reservation_reanchor_proof.go +++ b/pkg/maintainer/spv/reservation_reanchor_proof.go @@ -413,10 +413,23 @@ func reservationReanchorTransactionProofSubmitter( // signature only carries the transaction hash, so this function looks up // which reservation is still registered against the transaction's spent // anchor outpoint (ReservationByAnchorUtxo - the Bridge only clears that -// registration once the proof is accepted, so a match here is conclusive), -// then reads that reservation's current request nonce (the nonce of its -// in-flight action generation, since m1 allows at most one pending action -// per reservation at a time). +// registration once the proof is accepted, so a match on the outpoint is +// conclusive that this reservation's re-anchor has not yet landed). +// +// Deriving the request nonce is not as simple as reading the reservation's +// current RequestNonce: that field tracks the reservation's live action +// generation, which can have moved on since this transaction was discovered +// (e.g. the original re-anchor action timed out and a new action generation, +// possibly with a different target wallet, was requested while this +// function's caller was waiting out requiredConfirmations).

If that assumption is false, getUnprovenReservation- ReanchorTransactions' per-event Pending check would keep returning the same transaction and both branches would log the same warning every tick.

Both now call through to the real check/notify and proof-assembly paths. cmd/start.go now wires the reservation watchers directly against the Chain handle instead of threading them through tbtc.Initialize via the now-removed ReservationWatchersWirer callback type, since cmd/start.go already imports both tbtc and spv and there is no import-cycle reason for the indirection. clientinfo.NewPerformanceMetrics now takes the reservations-enabled flag so reservation action metrics are only registered when the feature is on. Also: - guard empty WalletMembersResolverFunc results before notifying watchers - fix nonce walk start in the action-timeout watcher - align nonce-base convention across SPV watchers (1-based) - fail-safe hasPendingAction on RPC error instead of assuming no action - remove dead depositToReservationKey identity-copy indirection - fix Errorf missing err argument in the stranding watcher - delete duplicate ReservationParametersFull declarations - add chain-error passthrough, notifier-error resilience, exact-timeout- boundary, and nil-notifier coverage for the stranding and stale-deposit watchers --- cmd/start.go | 40 +- config/config_test.go | 4 + pkg/maintainer/spv/chain.go | 27 + pkg/maintainer/spv/chain_test.go | 246 +++++++--- pkg/maintainer/spv/config.go | 16 +- .../spv/reservation_acceptance_proof.go | 192 +++++++- .../spv/reservation_action_timeout_watch.go | 287 +++++++---- .../reservation_action_timeout_watch_test.go | 78 +-- pkg/maintainer/spv/reservation_proof_loop.go | 463 ++++++++++++++++++ .../spv/reservation_reanchor_proof.go | 9 + .../spv/reservation_stale_deposit_watch.go | 47 +- .../reservation_stale_deposit_watch_test.go | 174 ++++++- .../spv/reservation_stranding_watch.go | 1 + .../spv/reservation_stranding_watch_test.go | 72 +++ pkg/maintainer/spv/reservation_wiring.go | 315 ++++++++---- pkg/maintainer/spv/spv.go | 86 +--- pkg/tbtc/chain.go | 23 - pkg/tbtc/chain_test.go | 4 - pkg/tbtc/coordination.go | 21 + pkg/tbtc/coordination_test.go | 1 + pkg/tbtc/node.go | 8 + pkg/tbtc/node_executors.go | 1 + pkg/tbtc/tbtc.go | 54 +- test/config.json | 5 +- test/config.toml | 3 + test/config.yaml | 2 + 26 files changed, 1714 insertions(+), 465 deletions(-) create mode 100644 pkg/maintainer/spv/reservation_proof_loop.go diff --git a/cmd/start.go b/cmd/start.go index 41b33cab7c..a938fefc1b 100644 --- a/cmd/start.go +++ b/cmd/start.go @@ -93,7 +93,11 @@ func start(cmd *cobra.Command) error { // Wire performance metrics into network provider if available var perfMetrics *clientinfo.PerformanceMetrics if clientInfoRegistry != nil { - perfMetrics = clientinfo.NewPerformanceMetrics(ctx, clientInfoRegistry) + perfMetrics = clientinfo.NewPerformanceMetrics( + ctx, + clientInfoRegistry, + clientConfig.Tbtc.Reservations.Enabled, + ) // Type assert to libp2p provider to set metrics recorder // The provider struct is not exported, so we use interface assertion if setter, ok := netProvider.(interface { @@ -164,18 +168,6 @@ func start(cmd *cobra.Command) error { clientConfig.Tbtc.Reservations.Enabled, ) - // PR H: when reservations are enabled, hand tbtc.Initialize a - // wiring callback that constructs the reservation watchers in the - // spv package and subscribes them to the chain.

=?UTF-8?q?Piotr=20Ros=C5=82aniec?= Date: Tue, 1 Sep 2026 14:39:02 +0000 Subject: [PATCH 024/101] fix(tbtcpg): reservation acceptance/re-anchor correctness fixes and coverage Correctness: - populate BlindingFactor/RefundPublicKeyHash/RefundLocktime in the acceptance deposit instead of leaving them zeroed - set RequestNonce in proposeReservationAcceptance - compute the anchor/re-anchor fee dynamically (applyWalletTxFeeFloor) instead of a hardcoded constant - compare the net (post-fee) deposit amount against ReservationMinAmount - guard the pendingReservedDeposits check with MaxTotalAmount>0, then remove it entirely once the guard made it a strict, unreachable subset of the preceding global-cap check - fix the WalletReservationsAmount map-key bug and the fillBigInt16 truncation in the shared LocalChain test double; switch reservation map keys from truncated fixed-byte keys to the big.Int's full base-16 text so distinct keys can never collide - fix the AnchorUtxo nil-check to a value-based check, since the Go-side chain adapter always allocates a non-nil struct - add a bounds check in parseReservationReanchorTransactionInput - bound findTargetWallet's wallet-registration scan and findReservationAcceptanceCandidate's deposit re-scan to a look-back window with a per-wallet cursor instead of an unbounded eth_getLogs scan on every coordination window - add reservation action types to getActionsChecklist - remove dead reservationAcceptanceCandidate fields and the ReservationWatchersWirer indirection's tbtcpg-side leftovers Test coverage: - add scenario fixtures for the 4 previously-untested eligibility rejection branches (wallet reservations count cap, single-deposit cap, wallet aggregate cap, global total cap) plus the re-anchor task's no-live-wallet-target, non-Active-state skip, empty-reservations, and minimum-fee-floor branches - add TestNewProposalGenerator_ReservationsEnabled proving the reservationsEnabled constructor flag actually wires (or omits) the reservation tasks, closing the gap where a regression that always or never appended them would go undetected - replace the reservation acceptance/re-anchor proposal comparisons' reliance on deep.Equal, which silently reports no difference between any two distinct *big.Int values because big.Int's representation is entirely unexported, with explicit field-by-field comparators using .Cmp(); this also caught and fixes two pre-existing wrong expected ReanchorTxFee fixture values (1015 instead of the real computed 550) and adds RequestNonce to the acceptance comparison, which was silently never checked --- pkg/tbtcpg/chain_test.go | 15 +- .../internal/test/reservation_acceptance.go | 2 + .../reservation_acceptance_scenario_0.json | 3 +-

ReservationAnchorProposal, ReservedRedemptionProposal, ReservationReanchorProposal, and ReservationDissolutionProposal previously used a JSON Marshal/Unmarshal placeholder, unlike every other CoordinationProposal type in this package (Heartbeat, DepositSweep, Redemption, MovingFunds, MovedFundsSweep), which all marshal via pkg/tbtc/gen/pb. Added the four missing message types to message.proto and regenerated message.pb.go (protoc 3.21.12 installed for this). Moved the four proposals' Marshal/Unmarshal from reservation.go's JSON stubs into marshaling.go, matching the existing proto-based implementations' structure and field-encoding conventions (big.Int fees via .Bytes()/SetBytes(), fixed-size hashes/pubkey-hashes via byte-slice copy with a length check). Preserved the original JSON stubs' validation intent under proto3's zero-value-is-absence semantics: a request nonce of 0, or empty fee/reservation-key/hash bytes, are rejected the same way an explicitly-missing JSON field was. The original '== nil' checks on *big.Int fields don't carry over as-is - SetBytes never returns nil - so they're now byte-length checks on the wire field instead, which is the pattern every other proto-based proposal in this file already uses. Testing: extended the existing table-driven TestCoordinationMessage_MarshalingRoundtrip with the four new types (exact field-for-field equality through the wire, matching the existing test's own precision, not just the fuzz-style tests already covering every sibling type) plus four new TestFuzzCoordinationMessage_MarshalingRoundtrip_WithProposal crash-safety tests, matching the one-per-type convention. Rewrote the pre-existing TestReservationProposals_UnmarshalRejectsMissingIntegers (now TestReservationProposals_UnmarshalRejectsInvalidFields) to construct real protobuf payloads instead of JSON string literals, porting every original missing-field case plus two new structural cases (invalid hash/pubkey-hash length) that fall out of the new wire format. go test ./pkg/tbtc/...: 15/15 new/changed tests pass, full package suite passes (146s), -race clean (156s). gofmt/vet clean on all 6 changed files. --- pkg/tbtc/gen/pb/message.pb.go | 397 ++++++++++++++++++++++++++++++++-- pkg/tbtc/gen/pb/message.proto | 26 +++ pkg/tbtc/marshaling.go | 180 +++++++++++++++ pkg/tbtc/marshaling_test.go | 146 +++++++++++++ pkg/tbtc/reservation.go | 114 ---------- pkg/tbtc/reservation_test.go | 121 ++++++++--- 6 files changed, 823 insertions(+), 161 deletions(-) diff --git a/pkg/tbtc/gen/pb/message.pb.go b/pkg/tbtc/gen/pb/message.pb.go index 7496ad009d..41a7f348df 100644 --- a/pkg/tbtc/gen/pb/message.pb.go +++ b/pkg/tbtc/gen/pb/message.pb.go @@ -1,7 +1,7 @@ // Code generated by protoc-gen-go.

it never iterates pg.tasks directly. NewReservationAcceptanceTask and NewReservationReanchorTask are registered when config.Reservations.Enabled=true (tbtcpg.go:88-92), but with no checklist entry, Generate's per-window loop never selected them. Both tasks were structurally unreachable in production regardless of PR #4276/#4277's fixes. Every existing unit test for these tasks (reservation_acceptance_test.go, reservation_reanchor_test.go) calls task.Run(request) directly, bypassing getActionsChecklist/Generate entirely - which is why this was never caught by any prior PR's test suite. Fix: ActionReservationAnchor and ActionReservationReanchor are now appended unconditionally, checked on every coordination window like ActionRedemption (both are custody-critical - an unaccepted reservation or a stale re-anchor risks stranding, not just reduced throughput - unlike the frequency-gated sweep/moving-funds actions). A node with reservations disabled safely no-ops on these: Generate already treats a checklist action with no matching registered task as 'unsupported' and skips it without error (tbtcpg.go:131-135), the same mechanism that already gates every other optional per-node task. Testing: - Updated TestCoordinationExecutor_GetActionsChecklist and its _PostActivation sibling: every non-nil expected checklist now includes both new actions right after ActionRedemption, matching the real append order. Extended assertChecklistOrdering's priority map accordingly (Redemption=0, ReservationAnchor=1, ReservationReanchor=2, then the existing sweep/moving-funds/ heartbeat priorities shifted). - Added TestCoordinationExecutor_GetActionsChecklist_ReservationActionsAlwaysPresent, a dedicated regression guard asserting both actions are present across pre/post-activation and 4th/non-4th windows, decoupled from the large table-driven test - would fail on its own if this wiring regresses. - go test ./pkg/tbtc/... ./pkg/tbtcpg/...: 476/476 pass. - go build ./... && go test ./...: full repo, 49 packages, zero FAIL. - gofmt/vet clean on both changed files. --- pkg/tbtc/coordination.go | 16 ++++- pkg/tbtc/coordination_test.go | 117 ++++++++++++++++++++++++++++------ 2 files changed, 112 insertions(+), 21 deletions(-) diff --git a/pkg/tbtc/coordination.go b/pkg/tbtc/coordination.go index 2dd75e9614..8eeb63e53a 100644 --- a/pkg/tbtc/coordination.go +++ b/pkg/tbtc/coordination.go @@ -591,9 +591,21 @@ func (ce *coordinationExecutor) getActionsChecklist( var actions []WalletActionType - // Redemption action is a priority action and should be checked on every - // coordination window. + // Redemption, reservation anchor, and reservation reanchor are priority + // actions and should be checked on every coordination window: like + // Redemption, they are custody-critical (an unaccepted reservation or a + // stale re-anchor risks reservation stranding, not just throughput), not + // throughput-heavy scans like the sweep/moving-funds actions gated below. + // + // A node that has not enabled the reservation feature + // (config.Reservations.Enabled=false) never registers a matching + // ProposalTask for these action types; pkg/tbtcpg.ProposalGenerator. + // Generate already treats a checklist action with no registered task as + // "unsupported" and skips it, so listing these unconditionally here is + // safe on non-reservation deployments. actions = append(actions, ActionRedemption) + actions = append(actions, ActionReservationAnchor) + actions = append(actions, ActionReservationReanchor) // Other actions should be checked with a lower frequency.

Scales TestCoordinationExecutor_Coordinate's existing 3-operator harness - deterministic keypairs, real per-operator localChain fakes, a real shared netlocal.BroadcastChannel, one goroutine per operator running coordinationExecutor.coordinate concurrently - to ReservationAnchorProposal and ReservationReanchorProposal. This exercises the real leader/follower coordination round-trip (checklist generation -> leader election -> broadcast -> follower validation -> convergence) that no mocked pkg/tbtcpg unit test can cover, since those call task.Run(request) directly and never go through coordinationExecutor.coordinate. It also exercises PR #4277's protobuf marshaling of both proposal types over a real wire round-trip, since every follower unmarshals the leader's broadcast coordinationMessage. Depends on PR #4278 (this branch's parent): before that fix, ActionReservationAnchor/ActionReservationReanchor never appeared in getActionsChecklist's output, so every operator's checklist search in these tests would fall through to NoopProposal and fail - confirmed by temporarily reverting the checklist fix and re-running (both new tests failed with the expected NoopProposal mismatch), then restoring it. Found and fixed one bug in this test's own harness during verification: both new tests initially shared one netlocal broadcast channel name. getBroadcastChannel's registry is keyed by name and never releases old channels, so under -race (which changed goroutine/channel-delivery timing enough to surface it in ~every run), the reanchor test's follower sometimes received a stale broadcast left over from the anchor test's leader. Fixed by giving each test its own channel name; re-verified stable across 10 repeated -race runs plus the full non-race and race suites.

add EndBlock to every AddPastDepositRevealedEvent call site so bounded look-back scans don't silently include events past the intended range. - Fix TestReservationAcceptanceTask_GetWalletError and TestReservationAcceptanceTask_DepositNotReserved fixtures to exercise the reachable code paths (matching EndBlock, correct wallet chain data seeding) instead of failing before reaching GetWallet. - Factor a shared estimateReservationFixedSizeTxFee helper used by both the acceptance and reanchor fee estimators; parameterize the exceeds-max error message per caller. - Add reservation_reanchor_scenario_8/9.json covering the dust-migration eligibility gate and a live wallet without a main UTXO re-anchor case. - Strengthen TestNewProposalGenerator_ReservationsEnabled to assert both reservation action types are dispatched independently, not just that Generate returns a non-nil error. --- pkg/tbtcpg/bitcoin_chain_test.go | 20 +- pkg/tbtcpg/chain.go | 13 - pkg/tbtcpg/chain_test.go | 28 +- pkg/tbtcpg/fee.go | 40 +++ .../reservation_reanchor_scenario_8.json | 34 +++ .../reservation_reanchor_scenario_9.json | 17 ++ pkg/tbtcpg/reservation_acceptance.go | 250 +++++++----------- pkg/tbtcpg/reservation_acceptance_test.go | 113 +++++++- pkg/tbtcpg/reservation_reanchor.go | 53 ++-- pkg/tbtcpg/reservation_reanchor_test.go | 40 ++- pkg/tbtcpg/tbtcpg_test.go | 17 +- 11 files changed, 393 insertions(+), 232 deletions(-) create mode 100644 pkg/tbtcpg/internal/test/testdata/reservation_reanchor_scenario_8.json create mode 100644 pkg/tbtcpg/internal/test/testdata/reservation_reanchor_scenario_9.json diff --git a/pkg/tbtcpg/bitcoin_chain_test.go b/pkg/tbtcpg/bitcoin_chain_test.go index e5cd80cf67..7832bf7a0e 100644 --- a/pkg/tbtcpg/bitcoin_chain_test.go +++ b/pkg/tbtcpg/bitcoin_chain_test.go @@ -14,6 +14,7 @@ type LocalBitcoinChain struct { transactions map[bitcoin.Hash]*bitcoin.Transaction transactionsConfirmations map[bitcoin.Hash]uint satPerVByteFeeEstimation map[uint32]int64 + txHashesByPublicKeyHash map[[20]byte][]bitcoin.Hash } func NewLocalBitcoinChain() *LocalBitcoinChain { @@ -21,6 +22,7 @@ func NewLocalBitcoinChain() *LocalBitcoinChain { transactions: make(map[bitcoin.Hash]*bitcoin.Transaction), transactionsConfirmations: make(map[bitcoin.Hash]uint), satPerVByteFeeEstimation: make(map[uint32]int64), + txHashesByPublicKeyHash: make(map[[20]byte][]bitcoin.Hash), } } @@ -104,7 +106,23 @@ func (lbc *LocalBitcoinChain) GetTransactionsForPublicKeyHash( func (lbc *LocalBitcoinChain) GetTxHashesForPublicKeyHash( publicKeyHash [20]byte, ) ([]bitcoin.Hash, error) { - panic("unsupported") + lbc.mutex.Lock() + defer lbc.mutex.Unlock() + + return lbc.txHashesByPublicKeyHash[publicKeyHash], nil +} + +// SetTxHashesForPublicKeyHash wires the wallet's transaction history for +// GetTxHashesForPublicKeyHash, used by tbtc.DetermineWalletMainUtxo to +// locate the wallet's main UTXO among its past transactions. +func (lbc *LocalBitcoinChain) SetTxHashesForPublicKeyHash( + publicKeyHash [20]byte, + hashes []bitcoin.Hash, +) { + lbc.mutex.Lock() + defer lbc.mutex.Unlock() + + lbc.txHashesByPublicKeyHash[publicKeyHash] = hashes } func (lbc *LocalBitcoinChain) GetMempoolForPublicKeyHash( diff --git a/pkg/tbtcpg/chain.go b/pkg/tbtcpg/chain.go index c6fd10029a..fa804cdaac 100644 --- a/pkg/tbtcpg/chain.go +++ b/pkg/tbtcpg/chain.go @@ -248,19 +248,6 @@ type Chain interface { // have been revealed to the Bridge but not yet accepted by a wallet.

give ReservationsActivationBlock its own independent constant instead of aliasing DepositSweepEveryWindowActivationBlock - node_coordination.go: add missing routing tests for the reservation anchor/reanchor dispatch cases - reservation.go: add TargetWalletPublicKeyHash guards to both live execute() paths and to ReservationReanchorProposal.Unmarshal; add ActionType/State pending guards before assembling anchor/reanchor transactions; bound the anchor action's deposit-revealed event scan; add real execute()-path tests using localChain/localBitcoinChain test doubles; remove the reserved-redemption and reservation- dissolution proposal/marshaling/assembly scaffolding that ships with no producer, dispatch case, or wired validator in this milestone - marshaling.go: migrate the two surviving reservation proposal types (anchor, re-anchor) from encoding/json to protobuf, matching every other coordination proposal type; restore the required-field validation the migration had dropped - wallet.go: remove the two now-unused WalletActionType values, preserving their wire-format numeric slots - chain.go: remove 17 ReservationChain interface members with zero production callers (unused on-chain event subscriptions and reads) - node.go/node_executors.go/tbtc.go: remove the reservationsEnabled field threaded from config into coordinationExecutor - it stopped being read once the checklist gate above was fixed to depend only on the activation block, and task-registration gating already happens independently via tbtcpg.NewProposalGenerator --- pkg/tbtc/chain.go | 130 ------ pkg/tbtc/chain_test.go | 157 ++----- pkg/tbtc/coordination.go | 17 +- pkg/tbtc/coordination_test.go | 73 +-- pkg/tbtc/gen/pb/message.pb.go | 222 ++++++++- pkg/tbtc/gen/pb/message.proto | 14 + pkg/tbtc/marshaling.go | 97 +++- pkg/tbtc/node.go | 26 +- pkg/tbtc/node_executors.go | 1 - pkg/tbtc/node_test.go | 65 +++ pkg/tbtc/reservation.go | 429 +---------------- pkg/tbtc/reservation_test.go | 858 ++++++++++++++-------------------- pkg/tbtc/tbtc.go | 18 +- pkg/tbtc/wallet.go | 19 +- pkg/tbtc/wallet_test.go | 29 +- 15 files changed, 874 insertions(+), 1281 deletions(-) diff --git a/pkg/tbtc/chain.go b/pkg/tbtc/chain.go index 36f1e57116..09e6b75868 100644 --- a/pkg/tbtc/chain.go +++ b/pkg/tbtc/chain.go @@ -446,14 +446,6 @@ type WalletProposalValidatorChain interface { }, ) error - // ValidateReservedRedemptionProposal validates the given reserved - // redemption proposal against the chain.

evict closed/terminated wallets from the discovery set instead of scanning an ever-growing history; scan from block 0 on the first pass so wallets registered before the look-back window are found; fix doc/behavior mismatches; add a Run-loop test driving two ticks - reservation_stale_deposit_watch.go: stop collapsing a transient RPC error into the same fallback path as a genuine unknown-action state; cache reveal timestamps instead of rescanning from genesis on every poll; keep tracking a pending acceptance on a Live wallet instead of dropping it, so a stuck anchor is still caught; fix doc mismatches - reservation_stranding_watch.go: invert the notification filter to an allow-list (State == Active only) so closed/pending/already-stranded reservations are no longer re-notified; fix constructor doc drift - reservation_wiring.go: wire a real WalletMembersResolver from the node instead of a permanent-error stub (the watcher and the node share the same process, contrary to the stub's standalone-process justification); return real errors instead of only logging; advance the stale-deposit scan cursor only when the whole batch classifies without error; track a notified marker so a deposit isn't re- notified every tick; fix stale doc references - reservation_acceptance_proof.go/reservation_reanchor_proof.go: unify the acceptance/re-anchor input parsers into one helper; fix the truncated doc comment and the dual-purpose UTXO doc; fix the SubmitReservationProof call's argument order to match the actual interface signature; add negative-path test coverage for the metrics recorder and the unreachable key/nonce guards - reservation_proof_loop.go: replace the full-window rescan on every pass with an incremental event cursor and pending-action set, and reuse the generic wallet-hash dedup helper instead of a duplicate;

Fixes stale deposit snapshots, a cursor that never advanced on the no-candidate path, and unbounded candidate retention with no eviction rule. Also: derive the acceptance RequestNonce from chain state instead of a hardcoded 1 (a hardcoded nonce stalls the deposit forever after a timed-out retry bumps the on-chain nonce); guard against re-requesting acceptance for an already-accepted/settled reservation by checking past request events (fail-closed on RPC error) and reservation state; make the below-minimum check retryable since the minimum is a live chain parameter, and remove its now-duplicated dead copy. --- pkg/tbtcpg/reservation_acceptance.go | 371 +++++----- pkg/tbtcpg/reservation_acceptance_test.go | 798 +++++++++++++++++++++- 2 files changed, 945 insertions(+), 224 deletions(-) diff --git a/pkg/tbtcpg/reservation_acceptance.go b/pkg/tbtcpg/reservation_acceptance.go index b44978c192..62818009f1 100644 --- a/pkg/tbtcpg/reservation_acceptance.go +++ b/pkg/tbtcpg/reservation_acceptance.go @@ -4,8 +4,8 @@ import ( "context" "fmt" "math/big" + "sort" "strings" - "sync" "time" "github.com/ipfs/go-log/v2" @@ -21,24 +21,6 @@ import ( // sweep look-back window: 30 days at 12 seconds per block. const ReservationAcceptanceLookBackBlocks = uint64(216000) -// reservationAcceptanceRequestNonce is the acceptance action generation -// nonce.

Remove the cache and resolve the target wallet once per Run instead of once per reservation. Drop the unreachable hasPendingAction call already covered by the preceding Active-state check. --- pkg/tbtcpg/reservation_reanchor.go | 61 ++--- pkg/tbtcpg/reservation_reanchor_test.go | 299

Rewrite the comment to state the guard's real purpose: distinguishing an expected, benign skip (Warn-logged, deliberately not counted as a failed submission attempt) from a genuine error. Fix the skip Warnf to report the actually observed action type/state (via the new String() methods) instead of only the caller-supplied expected type formatted with bare %v. Fix a false-success log: a guard skip inside the submit closure returned nil, so proveReservationTransaction always logged 'successfully submitted proof' even when nothing was submitted. Add a sentinel error (errReservationActionNoLongerProvable) so the skip path is distinguishable from both a real submission and a real failure. Extract the two submit closures into named submitReservationAcceptanceActionProof / submitReservationReanchorActionProof functions so the re-anchor closure's wallet-field selection (event.TargetWalletPublicKeyHash, not SourceWalletPublicKeyHash) can be unit-tested directly, without going through Bitcoin transaction discovery (this package's local chain test double can only discover a transaction via the source wallet's outputs, which forces source and target to coincide in any end-to-end test and so can't catch a field swap between them). Test changes: - Fix TestVerifyReservationActionStillProvable_WrongActionType's fixture leaving TargetWalletPublicKeyHash at its zero value, which let the wallet-mismatch branch mask the action-type branch under test. - Consolidate the five near-duplicate TestVerifyReservationActionStillProvable_* tests into one table-driven TestVerifyReservationActionStillProvable, add a case for a genuine chain-read error (via the new localChain.getReservationActionErr injection field, instead of relying on 'no action installed' as an implicit error trigger) and a case for an absent/zero-value action (matching what the real chain adapter actually returns for a never-set entry). - Remove stale/inaccurate doc comments (dangling references to a 'prior design' and 'generic-loop adapter' that don't exist in this repo; a claim that a propagated error would abort the whole proving pass, when call sites always log-and-continue per event). - Add loop-level regression cases to TestProveReservationAcceptanceActions / TestProveReservationReanchorActions asserting zero submissions when the action is no longer pending at submission time. - Add TestSubmitReservationReanchorActionProof_UsesTargetWallet, which calls the extracted function directly (bypassing discovery) with a genuinely distinct source/target wallet, to catch a regression that swaps the two fields at the call site. --- pkg/maintainer/spv/chain_test.go | 5 + pkg/maintainer/spv/reservation_proof_loop.go | 167 +++-- .../spv/reservation_proof_loop_test.go | 643 ++++++++++++++---- 3 files changed, 613 insertions(+), 202 deletions(-) diff --git a/pkg/maintainer/spv/chain_test.go b/pkg/maintainer/spv/chain_test.go index 33cf5485a9..4e4027dd9f 100644 --- a/pkg/maintainer/spv/chain_test.go +++ b/pkg/maintainer/spv/chain_test.go @@ -106,6 +106,7 @@ type localChain struct { // Error-injection fields for the reservation watcher chain-error // passthrough tests: nil (the default) means the corresponding method // falls through to its normal, table-driven behavior. + getReservationActionErr error walletReservationsErr error isReservedDepositErr error reservedDepositWalletErr error @@ -952,6 +953,10 @@ func (lc *localChain) GetReservationAction( lc.mutex.Lock() defer lc.mutex.Unlock() + if lc.getReservationActionErr != nil { + return nil, lc.getReservationActionErr + } + key := buildReservationActionKey(reservationKey, requestNonce) action, ok := lc.reservationActions[key] if !ok { diff --git a/pkg/maintainer/spv/reservation_proof_loop.go b/pkg/maintainer/spv/reservation_proof_loop.go index f09ec36169..9dbaf0a4f7 100644 --- a/pkg/maintainer/spv/reservation_proof_loop.go +++ b/pkg/maintainer/spv/reservation_proof_loop.go @@ -2,6 +2,7 @@ package spv import ( "context" + "errors" "fmt" "math/big" "time" @@ -11,6 +12,13 @@ import ( "github.com/keep-network/keep-core/pkg/tbtc" ) +// errReservationActionNoLongerProvable is returned when a discovered +// transaction's action generation is no longer provable at submission time. +// This is an expected, benign skip rather than a submission failure. +var errReservationActionNoLongerProvable = errors.New( + "reservation action generation is no longer provable", +) + // reservationProofLookBackBlocks bounds the pending-action-request event // scan performed on the very first pass, before an incremental cursor // exists.

ReservationAnchorProposal, ReservedRedemptionProposal, ReservationReanchorProposal, and ReservationDissolutionProposal previously used a JSON Marshal/Unmarshal placeholder, unlike every other CoordinationProposal type in this package (Heartbeat, DepositSweep, Redemption, MovingFunds, MovedFundsSweep), which all marshal via pkg/tbtc/gen/pb. Added the four missing message types to message.proto and regenerated message.pb.go (protoc 3.21.12 installed for this). Moved the four proposals' Marshal/Unmarshal from reservation.go's JSON stubs into marshaling.go, matching the existing proto-based implementations' structure and field-encoding conventions (big.Int fees via .Bytes()/SetBytes(), fixed-size hashes/pubkey-hashes via byte-slice copy with a length check). Preserved the original JSON stubs' validation intent under proto3's zero-value-is-absence semantics: a request nonce of 0, or empty fee/reservation-key/hash bytes, are rejected the same way an explicitly-missing JSON field was. The original '== nil' checks on *big.Int fields don't carry over as-is - SetBytes never returns nil - so they're now byte-length checks on the wire field instead, which is the pattern every other proto-based proposal in this file already uses. Testing: extended the existing table-driven TestCoordinationMessage_MarshalingRoundtrip with the four new types (exact field-for-field equality through the wire, matching the existing test's own precision, not just the fuzz-style tests already covering every sibling type) plus four new TestFuzzCoordinationMessage_MarshalingRoundtrip_WithProposal crash-safety tests, matching the one-per-type convention. Rewrote the pre-existing TestReservationProposals_UnmarshalRejectsMissingIntegers (now TestReservationProposals_UnmarshalRejectsInvalidFields) to construct real protobuf payloads instead of JSON string literals, porting every original missing-field case plus two new structural cases (invalid hash/pubkey-hash length) that fall out of the new wire format. go test ./pkg/tbtc/...: 15/15 new/changed tests pass, full package suite passes (146s), -race clean (156s). gofmt/vet clean on all 6 changed files. --- pkg/tbtc/marshaling_test.go | 74 +++++++++++++++++++++++++++++++++++++ 1 file changed, 74 insertions(+) diff --git a/pkg/tbtc/marshaling_test.go b/pkg/tbtc/marshaling_test.go index 32b6977f0a..5fa3692918 100644 --- a/pkg/tbtc/marshaling_test.go +++ b/pkg/tbtc/marshaling_test.go @@ -231,6 +231,22 @@ func TestCoordinationMessage_MarshalingRoundtrip(t *testing.T) { SweepTxFee: big.NewInt(8000), }, }, + "with reservation anchor proposal": { + proposal: &ReservationAnchorProposal{ + DepositFundingTxHash: parseHash("709b55bd3da0f5a838125bd0ee20c5bfdd7caba173912d4281cae816b79a201b"), + DepositFundingOutputIndex: 2, + RequestNonce: 7, + AnchorTxFee: big.NewInt(1500), + }, + }, + "with reservation reanchor proposal": { + proposal: &ReservationReanchorProposal{ + ReservationKey: big.NewInt(424242), + RequestNonce: 4, + TargetWalletPublicKeyHash: toByte20("f87eb7ec3b15a3fdd7b57754d765694b3e0b4bf4"), + ReanchorTxFee: big.NewInt(1200), + }, + }, } walletPublicKeyHash := toByte20("aa768412ceed10bd423c025542ca90071f9fb62d") @@ -402,6 +418,64 @@ func TestFuzzCoordinationMessage_MarshalingRoundtrip_WithMovedFundsSweepProposal } } +func TestFuzzCoordinationMessage_MarshalingRoundtrip_WithReservationAnchorProposal(t *testing.T) { + for i := 0;

The original '== nil' checks on *big.Int fields don't carry over as-is - SetBytes never returns nil - so they're now byte-length checks on the wire field instead, which is the pattern every other proto-based proposal in this file already uses. Testing: extended the existing table-driven TestCoordinationMessage_MarshalingRoundtrip with the four new types (exact field-for-field equality through the wire, matching the existing test's own precision, not just the fuzz-style tests already covering every sibling type) plus four new TestFuzzCoordinationMessage_MarshalingRoundtrip_WithProposal crash-safety tests, matching the one-per-type convention. Rewrote the pre-existing TestReservationProposals_UnmarshalRejectsMissingIntegers (now TestReservationProposals_UnmarshalRejectsInvalidFields) to construct real protobuf payloads instead of JSON string literals, porting every original missing-field case plus two new structural cases (invalid hash/pubkey-hash length) that fall out of the new wire format. go test ./pkg/tbtc/...: 15/15 new/changed tests pass, full package suite passes (146s), -race clean (156s). gofmt/vet clean on all 6 changed files. --- pkg/tbtc/gen/pb/message.pb.go | 2 +- pkg/tbtc/reservation.go | 5 +---- pkg/tbtc/reservation_test.go | 9 +++++++-- 3 files changed, 9 insertions(+), 7 deletions(-) diff --git a/pkg/tbtc/gen/pb/message.pb.go b/pkg/tbtc/gen/pb/message.pb.go index 10ffa49071..3d5037d7a4 100644 --- a/pkg/tbtc/gen/pb/message.pb.go +++ b/pkg/tbtc/gen/pb/message.pb.go @@ -1,7 +1,7 @@ // Code generated by protoc-gen-go.

Scales TestCoordinationExecutor_Coordinate's existing 3-operator harness - deterministic keypairs, real per-operator localChain fakes, a real shared netlocal.BroadcastChannel, one goroutine per operator running coordinationExecutor.coordinate concurrently - to ReservationAnchorProposal and ReservationReanchorProposal. This exercises the real leader/follower coordination round-trip (checklist generation -> leader election -> broadcast -> follower validation -> convergence) that no mocked pkg/tbtcpg unit test can cover, since those call task.Run(request) directly and never go through coordinationExecutor.coordinate. It also exercises PR #4277's protobuf marshaling of both proposal types over a real wire round-trip, since every follower unmarshals the leader's broadcast coordinationMessage. Depends on PR #4278 (this branch's parent): before that fix, ActionReservationAnchor/ActionReservationReanchor never appeared in getActionsChecklist's output, so every operator's checklist search in these tests would fall through to NoopProposal and fail - confirmed by temporarily reverting the checklist fix and re-running (both new tests failed with the expected NoopProposal mismatch), then restoring it. Found and fixed one bug in this test's own harness during verification: both new tests initially shared one netlocal broadcast channel name. getBroadcastChannel's registry is keyed by name and never releases old channels, so under -race (which changed goroutine/channel-delivery timing enough to surface it in ~every run), the reanchor test's follower sometimes received a stale broadcast left over from the anchor test's leader. Fixed by giving each test its own channel name; re-verified stable across 10 repeated -race runs plus the full non-race and race suites.

Bound runReservationCoordinationRound's report wait with a 30s timeout instead of an unbounded channel receive: at coordinationBlock=24562800, coordinate()'s only cancel path takes ~28 simulated days to fire, so any follower-rejects-proposal regression would hang the goroutine and the test forever, killing every other pkg/tbtc test via the package-wide go test timeout. - Derive each test's broadcast channel name from t.Name() plus a per-invocation nonce instead of a hardcoded literal: the coordination leader intentionally keeps retransmitting for the active phase's duration, so a hardcoded name risks an earlier invocation's leader retransmitting into a later invocation's followers under -count=N or a future test reusing the name. - Migrate TestCoordinationExecutor_Coordinate onto the shared reservation-coordination helpers instead of its own duplicated inline fixture/report/sort logic, and collapse TestCoordinationExecutor_Coordinate_ReservationAnchor/Reanchor into one table-driven TestCoordinationExecutor_Coordinate_ReservationProposals. - Drop the now-unused sort in runReservationCoordinationRound (no assertion depended on report order) and the tautological reports-count assertions. - Stop aliasing the mock generator's returned pointer as the expected result in assertions, so the leader-side comparison isn't a vacuous pointer-identity check. - Correct four doc comments that overclaimed shared-state absence, stale branch provenance, and reanchor test chronology; add the missing public-key-hash comment in newReservationCoordinationWallet. Verified: go build ./..., go vet ./pkg/tbtc/..., gofmt clean, go test ./pkg/tbtc/... (145s, all pass), and the three affected tests under -race -count=10 (clean). --- pkg/tbtc/coordination_test.go | 608 +++++++++++----------------------- 1 file changed, 199 insertions(+), 409 deletions(-) diff --git a/pkg/tbtc/coordination_test.go b/pkg/tbtc/coordination_test.go index 38d2236ff3..1ffa1b8fa5 100644 --- a/pkg/tbtc/coordination_test.go +++ b/pkg/tbtc/coordination_test.go @@ -173,273 +173,6 @@ func TestWatchCoordinationWindows(t *testing.T) { expectWindow(1800) } -func TestCoordinationExecutor_Coordinate(t *testing.T) { - // Uncompressed public key corresponding to the 20-byte public key hash: - // aa768412ceed10bd423c025542ca90071f9fb62d. - publicKeyHex, err := hex.DecodeString( - "0471e30bca60f6548d7b42582a478ea37ada63b402af7b3ddd57f0c95bb6843175" + - "aa0d2053a91a050a6797d85c38f2909cb7027f2344a01986aa2f9f8ca7a0c289", - ) - if err != nil { - t.Fatal(err) - } - - // 20-byte public key hash corresponding to the public key above. - buffer, err := hex.DecodeString("aa768412ceed10bd423c025542ca90071f9fb62d") - if err != nil { - t.Fatal(err) - } - var publicKeyHash [20]byte - copy(publicKeyHash[:], buffer) - - parseScript := func(script string) bitcoin.Script { - parsed, err := hex.DecodeString(script) - if err != nil { - t.Fatal(err) - } - - return parsed - } - - coordinationBlock := uint64(900) - - type operatorFixture struct { - chain Chain - address chain.Address - channel net.BroadcastChannel - waitForBlockHeight func(ctx context.Context, blockHeight uint64) error - } - - generateOperator := func(privateKey int64) *operatorFixture { - // Generate operators with deterministic addresses that don't change - // between test runs.

A later test/invocation reusing a channel name would keep receiving an earlier invocation's stale, still- retransmitting messages for the lifetime of the test binary - three pre-existing tests (ExecuteLeaderRoutine, ExecuteFollowerRoutine, ExecuteFollowerRoutine_WithIdleLeader) still hardcode "test"/"test-idle" and were never covered by the minimum fix. - pkg/net/local/broadcast_channel_manager.go: give each channel a cancellable context instead of context.Background(), track the cancel funcs, and add ResetForTesting() to cancel every outstanding ticker and clear the registry. - pkg/tbtc/coordination_test.go: wire t.Cleanup(netlocal.ResetForTesting) into all four broadcast-channel-creation sites in this file (the shared reservation-coordination helper plus the three pre-existing hardcoded-name tests), so every test starts from an empty registry regardless of channel-name convention - removing the need for the per-invocation-nonce workaround to be the only safeguard.

Eviction now rewinds the cursor behind the lost event's block so the next pass re-fetches and rediscovers it, applied symmetrically to both the acceptance and re-anchor paths. The stale-deposit watcher's deriveTimeoutFromReveal re-ran a full 216,000-block eth_getLogs scan every poll tick for every deposit with no requested action yet, with no memoization of the derived, immutable timeout. Added a per-deposit-key memoization map so subsequent ticks skip straight to the timeout comparison. Also completes the reanchor-proof submission counters (2 of 10 return paths in submitReservationActionProof were still uncounted) and adds TestIsReservedDeposit_PointerIdentity, pinning the fix for this PR's own historical pointer-identity map-key bug. Several P2/P3 findings in this cluster (M-7 nonce-aware timeout check, WalletMembersResolver architecture, dead-code cluster removal, tautological guard removal, unused alias, startStaleDepositPoll testability) remain deferred - see spv-cluster-followups.md.

Bounded the scan to ReservationAcceptanceLookBackBlocks, matching every other event scan in the diff. - Added a vault-not-configured guard against the actual zero-address hex string the chain.Address converter produces (the prior check compared against "", which the converter never returns). - RequestNonce is predicted client-side before the on-chain write and was never reconciled by re-reading the reservation afterward; a follower would hard-fail GetReservationAction forever if the Bridge assigned a different nonce. Added hasPendingAction, a re-read-and- compare guard against duplicate in-flight requests, shared by both the acceptance and re-anchor paths. - maxActiveReservations==0 (the global circuit-breaker cap) was treated as unlimited instead of failing closed; added boundary tests at the exact ==cap/==cap+1 edge for all three amount-based caps. - Fixed the typed-nil interface return on the below-minimum path. Reservation re-anchor (M-27, resolved via tbtc-v2 source): the below-dust trigger requested a re-anchor from the client's ordinary operator key even though tbtc-v2's on-chain requestReservationReanchor caps that path to privileged callers, making the trigger dead code as shipped. Removed the privileged-caller trigger; wired NotifyMovingFundsBelowDust (permissionless, already present in the Bridge ABI but never called from this client) so a wallet whose reservations have already fully drained closes once its last reservation's own re-anchor completes and its main UTXO computes below the moving-funds dust threshold. Added a pre-check (AssembleReservationReanchorTransaction, build-and-discard) before requesting re-anchor, mirroring the acceptance path's existing pre-check. Moved hasPendingAction to reservation_acceptance.go, its only real caller, and corrected its doc comment.

add error-injection coverage. - Assert AnchorTransactionAssembly's returned proposal fields against the task-derived candidate, not just a hand-built fixture object; make the fixture's ValidateReservationAnchorProposal genuinely check the funding outpoint instead of always returning nil. - Delete the fixture's shadow ReservationParameters override/field; route through the base LocalChain's already-correct value-copy setter/getter instead. - Fix a test comment overclaiming exclusion is "strictly attributable" to one filter when multiple fixture gaps independently cause it. - Make the freshness-control test's RequestReservationAcceptance override actually record an event, so the dedup guard it's meant to exercise engages for real. - Pin RequestNonce==1 for the documented GetReservation fail-open path. - Make BoundaryChecks' three cap fields pointer-typed so a row can express production's real "0 = unlimited" semantic; add rows proving it. - Delete the dead reservedDeposits field/IsReservedDeposit override (zero production readers). - Add TestReservationAcceptanceTask_ValidateProposalError covering the previously-unexercised validateErr wrapping path. - Fix two misleading comments (wrong function attribution for the ReservationMinAmount gate; wrong description of the GetWallet error contract). - Add testReservationVaultAddress const, replacing 30+ inline literal duplicates. - Extract newBoundaryTestChain helper, replacing a ~13-line setup block duplicated across 16 call sites. pkg/tbtcpg/chain_test.go: - Fix binary.BigEndian.PutUint64 writing EndBlock bytes into the startBlock buffer instead of endBlock across 5 call sites, so EndBlock actually contributes to the event-filter cache key. pkg/chain/ethereum/tbtc_test.go: - Replace a stale tbtc.go line-range doc citation with a symbol reference. - Fold TestConvertReservationFromAbiType_DropsCumulativeReanchorFee into TestConvertReservationFromAbiType as a subtest, matching this file's one-test-per-converter convention. pkg/chain/ethereum/tbtc.go: - Add an in-tree TODO marking ValidateReservationAnchorProposal's deferred test coverage, since the docs describing that deferral don't exist in this checkout. --- pkg/chain/ethereum/tbtc.go | 4 + pkg/chain/ethereum/tbtc_test.go | 125 ++-- pkg/tbtcpg/chain_test.go | 10 +- pkg/tbtcpg/reservation_acceptance_test.go | 864 ++++++++++------------ 4 files changed, 480 insertions(+), 523 deletions(-) diff --git a/pkg/chain/ethereum/tbtc.go b/pkg/chain/ethereum/tbtc.go index 5f02098d1b..18a0407fe4 100644 --- a/pkg/chain/ethereum/tbtc.go +++ b/pkg/chain/ethereum/tbtc.go @@ -2525,6 +2525,10 @@ func (tc *TbtcChain) ReservationParameters() ( return convertReservationParametersFromAbiType(abiParameters), nil } +// TODO(test-coverage): ValidateReservationAnchorProposal has no direct unit +// test coverage.

Errors are now logged and the event stays pending until a successful read shows a terminal state. - Delete the unused wallet-event adapter types and their test-only production wrapper functions; retarget their tests at the candidate-map/predicate logic actually used in production. - Enforce the same fee<=TxMaxFee bound in the acceptance matcher's not-found branch as the found branch, instead of only OutputValue>0. --- pkg/maintainer/spv/reservation_proof_loop.go | 198 +------ .../spv/reservation_proof_loop_test.go | 552 +++--------------- 2 files changed, 95 insertions(+), 655 deletions(-) diff --git a/pkg/maintainer/spv/reservation_proof_loop.go b/pkg/maintainer/spv/reservation_proof_loop.go index 065c8941cb..8d29221100 100644 --- a/pkg/maintainer/spv/reservation_proof_loop.go +++ b/pkg/maintainer/spv/reservation_proof_loop.go @@ -171,52 +171,6 @@ func submitReservationReanchorActionProof( ) } -// reservationAcceptanceWalletEvent adapts -// *tbtc.ReservationAcceptanceRequestedEvent to the walletEvent interface -// (see spv.go) so uniqueWalletPublicKeyHashes can be reused here instead of -// a reservation-specific duplicate of the same dedup logic. -type reservationAcceptanceWalletEvent struct { - *tbtc.ReservationAcceptanceRequestedEvent -} - -// GetWalletPublicKeyHash implements walletEvent. -func (e reservationAcceptanceWalletEvent) GetWalletPublicKeyHash() [20]byte { - return e.WalletPublicKeyHash -} - -// reservationReanchorWalletEvent adapts -// *tbtc.ReservationReanchorRequestedEvent to the walletEvent interface (see -// spv.go) so uniqueWalletPublicKeyHashes can be reused here instead of a -// reservation-specific duplicate of the same dedup logic. -type reservationReanchorWalletEvent struct { - *tbtc.ReservationReanchorRequestedEvent -} - -// GetWalletPublicKeyHash implements walletEvent. -func (e reservationReanchorWalletEvent) GetWalletPublicKeyHash() [20]byte { - return e.SourceWalletPublicKeyHash -} - -func wrapReservationAcceptanceEvents( - events []*tbtc.ReservationAcceptanceRequestedEvent, -) []reservationAcceptanceWalletEvent { - wrapped := make([]reservationAcceptanceWalletEvent, len(events)) - for i, event := range events { - wrapped[i] = reservationAcceptanceWalletEvent{event} - } - return wrapped -} - -func wrapReservationReanchorEvents( - events []*tbtc.ReservationReanchorRequestedEvent, -) []reservationReanchorWalletEvent { - wrapped := make([]reservationReanchorWalletEvent, len(events)) - for i, event := range events { - wrapped[i] = reservationReanchorWalletEvent{event} - } - return wrapped -} - // reservationProofScanState persists the incremental event-scan cursor and // the set of still-pending action-request events across successive passes // of runReservationProofLoop, so proveReservationAcceptanceActions and @@ -227,28 +181,18 @@ func wrapReservationReanchorEvents( type reservationProofScanState struct { acceptanceLastScannedBlock uint64 pendingAcceptanceEvents map[string]*tbtc.ReservationAcceptanceRequestedEvent - acceptanceRetries map[string]uint reanchorLastScannedBlock uint64 pendingReanchorEvents map[string]*tbtc.ReservationReanchorRequestedEvent - reanchorRetries map[string]uint } func newReservationProofScanState() *reservationProofScanState { return &reservationProofScanState{ pendingAcceptanceEvents: make(map[string]*tbtc.ReservationAcceptanceRequestedEvent), - acceptanceRetries: make(map[string]uint), pendingReanchorEvents: make(map[string]*tbtc.ReservationReanchorRequestedEvent), - reanchorRetries: make(map[string]uint), } } -// maxReservationActionLoadRetries is the maximum number of consecutive -// passes GetReservationAction may fail for a tracked pending event before -// the event is evicted from the pending map to avoid unbounded map growth -// and log spam on unrecoverable RPC/chain errors. -const maxReservationActionLoadRetries = 3 - // reservationEventKey identifies one reservation action generation, unique // across both the acceptance and re-anchor pending-event maps. func reservationEventKey(reservationKey *big.Int, requestNonce uint64) string { @@ -425,9 +369,6 @@ func proveReservationAcceptanceActions( // Re-check every tracked event's on-chain action state, evict settled/stale // ones, and group still-pending events by wallet public key hash. - // nextScannedBlock starts at currentBlock but is pulled back by any - // eviction below, so a rewind survives the final cursor update. - nextScannedBlock := currentBlock walletEvents := make(map[[20]byte][]*tbtc.ReservationAcceptanceRequestedEvent) for key, event := range state.pendingAcceptanceEvents { action, err := spvChain.GetReservationAction( @@ -435,47 +376,15 @@ func proveReservationAcceptanceActions( event.RequestNonce, ) if err != nil { - state.acceptanceRetries[key]++ - if state.acceptanceRetries[key] >= maxReservationActionLoadRetries { - // Eviction is non-lossy: rewind the cursor behind the - // lost event's block so the next pass re-fetches the - // range and rediscovers the event.
