Each iteration rebuilds 1000 map entries between

Inline comments:
In `@pkg/beacon/dkg/marshaling.go`:
- Around line 69-80: Validate pbThresholdSigner.MemberIndex and each memberID in
the group-public-key-shares map against group.MaxMemberIndex before converting
them to group.MemberIndex. Reject out-of-range values, including oversized
values such as 256, so scalar assignments and map keys cannot wrap or collide;
add regression coverage for both oversized scalar and map-key inputs.
In `@pkg/beacon/dkg/result/marshaling_test.go`:
- Around line 52-60: Check and handle the pbutils.RoundTrip error in both fuzz
tests: pkg/beacon/dkg/result/marshaling_test.go lines 52-60 and
pkg/protocol/inactivity/marshaling_test.go lines 51-59. Store the returned error
and fail the corresponding test when it is non-nil, while preserving the
existing valid fuzz-input setup.
In `@pkg/beacon/gjkr/marshaling_test.go`:
- Around line 456-457: Update the key-pair generation in the benchmark,
including both the lines around kp1/kp2 and the later generation around lines
473–474, to capture each error and call b.Fatal immediately before accessing the
resulting key pair. Preserve the existing benchmark flow when generation
succeeds.
In `@pkg/bitcoin/transaction_builder_test.go`:
- Around line 650-672: Update each ComputeSignatureHashes benchmark to call and
validate the result once before b.ResetTimer(), failing the benchmark via
b.Fatalf or equivalent if an error occurs; keep the timed loop focused on
successful computation without discarding errors.
In `@pkg/chain/ethereum/tbtc_dkg.go`:
- Around line 168-175: Update validateMemberIndex to reject chain member indexes
below 1 as well as values above group.MaxMemberIndex, preserving the existing
invalid-value error behavior for both bounds. Keep the valid range 1 through
group.MaxMemberIndex inclusive.
- Around line 495-512: Update parseDkgResultValidationOutcome to return an error
instead of panicking when outcome is a nil pointer, points to a non-struct
value, or points to a struct with no fields. Validate the dereferenced value
before calling Field(0), while preserving the existing boolean-field parsing and
error behavior for unsupported field types.
In `@pkg/chain/ethereum/tbtc_redemption.go`:
- Around line 98-103: Update the pending redemption request error formatting to
avoid double-encoding the redemption key: in the error construction around
redemptionKey.Text(16), use a string-compatible format for the returned text (or
format the big integer directly with hexadecimal). Preserve the existing key and
underlying error details.
- Around line 57-65: Update the RedemptionRequestedEvent conversion to assign
convertedEvent.TxMaxFee from event.TxMaxFee, while leaving TreasuryFee mapped
from event.TreasuryFee.
In `@pkg/chain/ethereum/tbtc_wallet.go`:
- Around line 109-115: Update the missing-wallet error in the wallet lookup flow
to format the requested walletPublicKeyHash instead of the zero-valued wallet
response, while preserving the existing error message and return behavior.
In `@pkg/clientinfo/clientinfo.go`:
- Line 5: Update the pprof setup around Registry.EnableServer so EnablePprof
gates registration and does not rely on the net/http/pprof init-time
registration on http.DefaultServeMux. Use an isolated server mux, explicitly
register the pprof handlers only when EnablePprof is true, and provide that mux
to the server so disabling the option leaves /debug/pprof/ unavailable.
Apply the same fix in `@docs/profiling.md` around lines 5 - 8: The documentation
promises opt-in profiling, so it is covered by the same registration and
exposure fix.
In `@pkg/maintainer/spv/spv.go`:
- Around line 279-303: Add exported clientinfo constants for both proof-skip
counter names, pre-register them in PerformanceMetrics, and update the spv
proof-skip IncrementCounter calls to use those constants instead of string
literals. Ensure the existing metrics endpoint exposes both counters.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
Honor EnablePprof and avoid exposing handlers through the default mux.
Importing net/http/pprof registers handlers on http.DefaultServeMux, and the client-info server serves that mux when no handler is supplied. As a result, /debug/pprof/ remains available even when EnablePprof is false. Register pprof handlers only when enabled and serve them through an isolated mux, or otherwise ensure the disabled setting prevents endpoint exposure.

In `@pkg/beacon/gjkr/marshaling_test.go`:
- Around line 456-457: Update the key-pair generation in the benchmark,

473–474, to capture each error and call b.Fatal immediately before accessing the
resulting key pair. Preserve the existing benchmark flow when generation
succeeds.
In `@pkg/bitcoin/transaction_builder_test.go`:
- Around line 650-672: Update each ComputeSignatureHashes benchmark to call and
validate the result once before b.ResetTimer(), failing the benchmark via
b.Fatalf or equivalent if an error occurs; keep the timed loop focused on
successful computation without discarding errors.
In `@pkg/chain/ethereum/tbtc_dkg.go`:
- Around line 168-175: Update validateMemberIndex to reject chain member indexes
below 1 as well as values above group.MaxMemberIndex, preserving the existing
invalid-value error behavior for both bounds. Keep the valid range 1 through
group.MaxMemberIndex inclusive.
- Around line 495-512: Update parseDkgResultValidationOutcome to return an error
instead of panicking when outcome is a nil pointer, points to a non-struct
value, or points to a struct with no fields. Validate the dereferenced value
before calling Field(0), while preserving the existing boolean-field parsing and
error behavior for unsupported field types.
In `@pkg/chain/ethereum/tbtc_redemption.go`:
- Around line 98-103: Update the pending redemption request error formatting to
avoid double-encoding the redemption key: in the error construction around
redemptionKey.Text(16), use a string-compatible format for the returned text (or
format the big integer directly with hexadecimal). Preserve the existing key and
underlying error details.
- Around line 57-65: Update the RedemptionRequestedEvent conversion to assign
convertedEvent.TxMaxFee from event.TxMaxFee, while leaving TreasuryFee mapped

to format the requested walletPublicKeyHash instead of the zero-valued wallet
response, while preserving the existing error message and return behavior.
In `@pkg/clientinfo/clientinfo.go`:
- Line 5: Update the pprof setup around Registry.EnableServer so EnablePprof
gates registration and does not rely on the net/http/pprof init-time
registration on http.DefaultServeMux. Use an isolated server mux, explicitly
register the pprof handlers only when EnablePprof is true, and provide that mux
to the server so disabling the option leaves /debug/pprof/ unavailable.
Apply the same fix in `@docs/profiling.md` around lines 5 - 8: The documentation
promises opt-in profiling, so it is covered by the same registration and
exposure fix.
In `@pkg/maintainer/spv/spv.go`:
- Around line 279-303: Add exported clientinfo constants for both proof-skip
counter names, pre-register them in PerformanceMetrics, and update the spv
proof-skip IncrementCounter calls to use those constants instead of string
literals. Ensure the existing metrics endpoint exposes both counters.

…gate hardening Confirmed bugs and gate gaps from PR #4256 review (decisions #6/#7 plus four related P1 chores), landed in this PR per the same attribution reasoning as the chain-adapter split: - tbtc_redemption.go: convertedEvent.TxMaxFee was assigned from event.TreasuryFee instead of event.TxMaxFee, so every observed redemption event carried the treasury fee as its max fee. - tbtc_dkg.go: validateMemberIndex only checked the upper bound; add chainMemberIndex.Sign() <= 0 so index 0 and negative values are rejected too. - client.yml: pin benchstat to a fixed pseudo-version (was @latest, meaning CI could start failing with no code change); lower the regression gate from +20% to +12% (benchstat already treats ±10% as noise, so +20% let real regressions in the 12-18% band through); add dev to the top-level push trigger and to client-bench's run condition so merges to dev exercise the integration tests and the benchmark gate instead of only main. - ephemeral.UnmarshalPublicKey, tecdsa/{dkg,signing}/protocol.go: the ECDH-time (deferred) unmarshal error used %v, which drops the error chain. Switch to %w and add ephemeral.ErrInvalidPublicKey as a matchable sentinel, so any future retry-policy code can classify the failure with errors.Is instead of parsing the message string. TestGenerateSymmetricKeys_CorruptEphemeralPublicKeyBytes in both packages now asserts errors.Is(err, ephemeral.ErrInvalidPublicKey).

Fix the branch synchronization instructions.
Do not instruct maintainers to merge every sub-PR into both dev and main. That removes those changes from the cumulative dev → main release diff.
Do not instruct maintainers to fast-forward dev to main. If both branches contain unique commits, fast-forward is impossible. Merge or rebase the latest main into dev, then merge the release-tracking PR into main.

Expand malformed-input coverage for DKG result assembly. Add member indexes 0 and -1 alongside 254, 255, and 256, plus malformed targets for nil pointers, non-struct pointers, and empty-struct pointers. These cases should assert validation errors rather than panics, so removing either the lower-bound or input-shape guard fails the tests.

Return a copy instead of exporting the mutable *big.Int.
Keep the canonical target private. Export a function that returns new(big.Int).Set(canonicalTarget), and update all callers to invoke it. An exported *big.Int allows external packages to mutate or replace the value used by relay validation and SPV classification.

Handle zero MaxProofHeaders before starting the SPV maintainer.
The CLI flag supplies DefaultMaxProofHeaders, but direct or flagless Config construction leaves the field at zero. getProofInfo then returns proofSkipExceededMaxHeaders before reading any header. Normalize zero to DefaultMaxProofHeaders or reject it before startup.

Reject invalid wallet fee policies during initialization.
Negative values are silently ignored, and the CLI flags provide no validation. A configured ratio such as 1/4 is accepted, so tbtcpg.applyWalletTxFeeFloor can reduce a 100 sat/vByte estimate to 25 sat/vByte. Resolve zero values to defaults, require positive effective values, require Numerator >= Denominator, and return the validation error from Initialize before updating the package-level policy variables. Update pkg/tbtc/tbtc_test.go for the new return value.

Correct the maxWalletTxVsize rationale.
The comment states 10,000,000 vbytes is "~2x Bitcoin block weight". A Bitcoin block is capped at 4,000,000 weight units, which is 1,000,000 vbytes. The bound is therefore about 10x the maximum block vsize, not 2x. The value itself is a safe sanity bound; only the stated rationale is wrong.
📝 Proposed comment fix
- maxWalletTxVsize int64 = 10_000_000 // 10M vbytes; ~2x Bitcoin block weight.
+ maxWalletTxVsize int64 = 10_000_000 // 10M vbytes; ~10x the 1M vbyte max block size.
maxWalletTxEstimatedFee int64 = 1_000_000_000 // 1e9 satoshis = 10 BTC.📝 Committable suggestion

## Summary A second, focused batch of low-risk code-quality improvements across the node, continuing the cleanup in #4185. The changes reduce duplication, remove dead code, add missing test coverage, and fix two latent correctness issues found while cleaning up. No feature or protocol behavior changes beyond the two fixes noted below. Targets `dev`. The branch now includes current `dev` while preserving these refactors and the newer proof-skip metrics. Merge this foundation before #4190, then the maintainer follow-ups #4290 and #4291. Refs #3664. ## Fixes (behavior) - **fix(beacon): abort protocol setup when channel filter cannot be set** — `JoinDKGIfEligible` and `GenerateRelayEntry` previously logged and then continued when `SetFilter` failed, running the protocol on an unfiltered broadcast channel that would accept messages from operators outside the group. Both now fail closed and abort before launching the protocol goroutines. - **fix(libp2p): keep SetMetricsRecorder param anonymous for cmd wiring** — `cmd.start` wires the performance metrics recorder into the libp2p provider via a structural assertion against an anonymous interface. Naming that interface would silently break the assertion at runtime (metrics stop being recorded) with no build or test failure. A guard test now pins the contract. ## Refactors (dedup / clarity) - **refactor(spv): dedupe unproven-transaction search and drop dead metrics singleton** — the four `getUnproven*Transactions` functions shared identical search scaffolding, now extracted into `unprovenSearchStartBlock` and `collectUnprovenWalletTransactions`. Also removes an unwired global metrics singleton. - **refactor(tbtcpg): extract shared capped-fee estimation** — moving-funds and moved-funds-sweep fee estimation shared the same size/fee/cap logic, now in `estimateCappedFee`. - **refactor(libp2p): name the repeated metrics-recorder interface** — replaces a repeated inline interface literal with a named type at the sites that can safely use it (see the fix above for the one that must stay anonymous). - **refactor(beacon): extract shared broadcast-channel filter helper** — the set-filter-and-abort logic (see the beacon fix) lived in two places; now in `setBroadcastChannelFilter`. - **refactor(gjkr): drop test-only receivedQualifiedSharesT field** — a member field that was only ever read by tests; coverage preserved by returning the value through the existing test helper. ## Tests - **test(ethereum): cover timestamp-based block search** — new unit tests for `closerBlock` / `GetBlockNumberByTimestamp`, previously only exercised via integration. - **test(spv): cover shared unproven-transaction search helper** — pins the stop-at-first-match branch (both directions) and the error paths of the extracted helper. - **test(beacon): cover broadcast-channel filter abort path** — asserts the fail-closed contract from the beacon fix. - **test(tbtc): synchronize follower routine instead of sleeping** — replaces a `time.Sleep(1s)` in a coordination test with deterministic synchronization. - **style: use idiomatic zero-value and any declarations** — minor, mechanical. ## Verification - Affected test suites pass: `pkg/beacon/...`, `pkg/maintainer/spv`, `pkg/tbtc`, `pkg/tbtcpg`, `pkg/net/libp2p`, `pkg/chain/ethereum`, `pkg/bitcoin/electrum`, and `pkg/clientinfo`. - Vet passes for the affected packages; the diff against `dev` passes `git diff --check`. - Repository-wide vet still reports a pre-existing protobuf lock copy in `pkg/tecdsa/signing/protocol.go:758`, outside this diff. - CI integration tests encountered `electrs-esplora` history/UTXO RPC timeouts ([run](https://github.com/threshold-network/keep-core/actions/runs/34071678452)). The Electrum source diff is only `interface{}` to `any`; the timed-out request paths and integration tests are unchanged. Other completed checks pass.
- add named DepositKey type replacing the anonymous struct used for DepositSweepProposal.DepositsKeys across tbtc, tbtcpg and ethereum - extract movingFundsSafetyMarginChain interface shared by ValidateMovingFundsSafetyMargin and isWalletPendingMovingFundsTarget - switch ParseWalletActionType on WalletActionType iota constants - collapse three identical frequency-window guards into a single guard
- add and register clientinfo deposit-sweep proof-submission metric constants, mirroring the redemption ones, and replace the raw metric name strings in the SPV maintainer with them - remove the getGlobalMetricsRecorder passthrough and call getMetricsRecorder directly - trim variable comments that restated the variable names in parseDepositSweepTransactionInputs, keeping the vault constraint note
The movingFundsSafetyMarginChain interface was inserted between the function's doc comment and its declaration, detaching the doc. Move the interface above the doc comment so it attaches again.
EstimateMovingFundsFee and EstimateMovedFundsSweepFee shared an identical virtual-size, fee-estimate, and cap-check block. Extract it into estimateCappedFee, parameterized by the size estimator, the cap, and the fee-too-high error to return.
…cs singleton - extract unprovenSearchStartBlock and collectUnprovenWalletTransactions, shared by the four getUnproven*Transactions functions - remove the package-level global metrics recorder and its setter/getter, which were never wired in production and always resolved to nil; the proof submission functions retain their metricsRecorder parameter as the DI seam
The receivedQualifiedSharesT (t_ji) map on the member struct was written and deleted on the production path but never read there; only tests consumed it. Remove it from the struct and keep only receivedQualifiedSharesS (s_ji), which is the actual reconstruction state. The share-count assertions now rely on the S map (populated identically), and the accusation tests obtain the t_ji shares from a value returned by the group-initialization helper.
Directly exercise collectUnprovenWalletTransactions, pinning the stop-at-first-match branch in both directions and the chain and predicate error paths that were previously only reached indirectly.
Assert setBroadcastChannelFilter surfaces the SetFilter error so callers abort instead of proceeding on an unfiltered channel that would accept messages from operators outside the group.
unprovenSearchStartBlock returned currentBlock - historyDepth without guarding the subtraction. On short chains where historyDepth exceeds the current tip the unsigned subtraction wraps to a near-maximum block number, silently changing the search range. Clamp to the genesis block instead. This preserves behavior on mainnet, where the tip always dwarfs the configured history depth.
Replace the hand-rolled blockOutOfRangeError struct with a plain errors.New sentinel; it was only ever used as an opaque marker error.
The SPV proof submitters accept an optional metrics recorder, but the maintainer command never built one, so proof-submission counters were never recorded in production (the recorder was always passed as nil). Wire a clientinfo registry and PerformanceMetrics into the maintainer boot path and thread the recorder through maintainer.Initialize into the SPV maintainer, replacing the hardcoded nil at the deposit sweep and redemption submitters. Add ClientInfo to the maintainer config categories so the metrics endpoint port is parsed. Moving funds and moved funds sweep submitters accept the recorder to satisfy the submitter type but are not yet instrumented, as those proof submissions have no metrics counters defined.
…ilure Close review gaps on the SPV proof-submission metrics change: - assert the redemption success-path counters; the success test previously passed a nil recorder and asserted nothing, so a removed/misplaced success increment would go undetected. - cover the assemble-error failed-counter branch for both the deposit sweep and redemption provers (a realistic production failure mode); only the early zero-confirmations reject was asserted before. The on-chain-submit branch shares the same guard idiom but the local chain double cannot be forced to fail that call. - add a cmd test for initializeMaintainerMetrics: a 0 client-info port yields a nil recorder, guarding the sole production metrics on/off gate against an inverted condition.
…ntract - list the six SPV proof-submission counters in performance-metrics.adoc; this change is what makes them observable in production. - reframe the MetricsRecorder doc as an API contract (callers must treat nil as "metrics off" and guard every call) instead of the rot-prone "all call sites guard against it" status claim.
- cmd: add enabled-path test for initializeMaintainerMetrics using an ephemeral port and a stub BlockCounter, guarding against a regression that would silently disable production SPV metrics - spv: cover the parse-input-error metrics branch for deposit sweep and redemption proof submission - spv: add error-injection fields to the localChain test double and cover the previously untestable on-chain-submit failure metrics branch - docs: document that the maintainer command opens the client-info endpoint on all interfaces on port 9601 by default, and how to disable it
Rebasing feat/maintainer-spv-metrics onto the updated chore/code-quality-followups base surfaced several places where automatic conflict resolution dropped or duplicated content that the PR's own commits depend on: - cmd/maintainer.go: pass the whole ClientInfo config struct to clientinfo.Initialize, not just its Port field - pkg/clientinfo/performance.go: de-duplicate the wallet-action counters and restore the SPV proof-skip counters (registration and constants) that the rebase base had stripped along with the proof-submission counters - pkg/clientinfo/performance_test.go: restore the counter-registration tests for the deposit-sweep and SPV proof-skip counters - pkg/maintainer/spv/spv.go: restore the clientinfo import and the metrics-recording calls in the outside-relay-range and exceeded-max-headers skip branches - pkg/maintainer/spv/spv_test.go: restore the recordingMetricsRecorder test double and per-branch counter assertions in TestProveTransactions - trivial blank-line/whitespace fixups left by the merge in deposit_sweep.go, moving_funds.go, ethereum_timestamp_test.go and protocol_accusations_test.go Verified against the pre-rebase branch tip: every remaining diff is a legitimate independent addition from the new base (extra test coverage, the estimateCappedFee relocation to tbtcpg/fee.go). Full build, vet, and test suite pass (89 packages, 1763 tests).
…, added test coverage - cmd/start.go: run rpcHealthChecker.Start(ctx) in a goroutine so a slow or unavailable RPC no longer delays beacon/tbtc initialization, matching the maintainer startup path. - docs/performance-metrics.adoc: document the previously-omitted rpc_eth_response_time_seconds, rpc_btc_response_time_seconds, and rpc_btc_health_check_benign_errors_total metrics; update the documented default check interval to match the code change below; clarify the last-failure-timestamp metric description. - pkg/clientinfo/rpc_health.go: reorder checkBitcoinHealth's doc comment to match execution order; record btcLastCheck at probe completion (completedAt) instead of at start, matching the Ethereum probe; raise the default check interval to 60s so it no longer equals the 30s probe timeout, leaving an idle gap between probes during an outage instead of re-probing back-to-back. - pkg/clientinfo/performance.go: retitle the maintainer health metrics comment block so it no longer implies all seven constants are about discovery/proof-info errors when only two are. - cmd/maintainer_test.go: expand the nil-safety comment to name all three parameters the disabled-path test relies on being nil-safe, not just the block counter. - pkg/maintainer/spv/spv_test.go: update recordingMetricsRecorder's doc comment to reflect that it now captures SetGauge calls too. - pkg/maintainer/spv/health_test.go: cover the IdleBackoffTime > RestartBackoffTime branch of the max-backoff calculation, and cover mid-cycle context cancellation between proof tasks. - pkg/clientinfo/rpc_health_test.go: verify the periodic health-check goroutines actually stop probing after context cancellation.
…spacing - pkg/maintainer/spv/spv.go: proofSkipReason's doc comment now again notes that callers both log and record metrics on skip, matching the IncrementCounter calls in both skip branches (the shorter dev-side wording predates those calls being restored). - docs/performance-metrics.adoc: add the blank line AsciiDoc requires before a section header, dropped when merging the redemption-proposal and SPV proof-submission metrics sections.
The flag is registered with cobra's UintVar, which accepts 0, and nothing validated the parsed value. The 144 default only covers the case where the flag is omitted, so --spv.maxProofHeaders 0 reached the proof assembly loop. getProofInfo compares the running header count against the bound at loop entry, with the count starting at zero, so a zero bound returns proofSkipExceededMaxHeaders on the first iteration for every transaction. That disables SPV proving entirely while logging each transaction as possibly permanently unprovable, which reads as a chain condition rather than a misconfiguration. Reject the value at startup rather than normalizing it to the default, so an explicit instruction is not silently replaced. Validation runs before any chain connection is attempted.
The release process described sub-PRs merging into dev and main before closing. If sub-PRs also landed on main, the aggregation PR's diff would be empty and there would be nothing left to release, contradicting the adjacent text describing that diff as what is queued for the next release. The maxWalletTxVsize comment called 10M vbytes roughly 2x a Bitcoin block weight. A block is capped at 4,000,000 weight units, which is 1,000,000 vbytes, so the bound is about 10x a maximum block's vsize; the original also conflated vbytes with weight units.
Three follow-up fixes to the prior `fix: address validated review findings` commit, addressing findings raised by the post-PR multi-perspective review: - pkg/tbtcpg/fee.go: the bufferedFloorRate overflow guard formatted its error with `tbtc.MinWalletTxSatPerVByteFee` instead of the value that actually triggered the check (`bufferedFloorRate`). Print the correct value so operators diagnosing a huge `WalletTxFeeBufferPercent` see the buffered rate that overflowed rather than the bare floor. - pkg/bitcoin/electrum/electrum.go: drop the redundant raw `strings.Contains(rawURL, "://")` check in `validateServerURL`. The parsed `u.Scheme == ""` switch arm already rejects the same family of malformed URLs with the same error message; the raw check duplicated the work. - solidity/ecdsa/scripts/test-eslint-policy.test.mjs (new) + solidity/ecdsa/package.json: add an automated regression test for the SIGINT/SIGTERM cleanup contract in `test-eslint-policy.mjs`. The script had no test for the signal-handler path; the PR description relied on a manual smoke only. The new file uses Node's built-in test runner to spawn the script as a child process, interrupt it with SIGINT and SIGTERM mid-run, and assert no `policy-fixture-*.ts` files remain. Wired into the existing `lint:eslint-policy` script so it runs as part of `yarn lint`.
The round-trip helper's error was discarded at 38 call sites, which hid three fuzz generators that could never produce a value the marshaler accepts. fuzzEphemeralPublicKey fuzzed X and Y directly, so the point was almost never on secp256k1 and SerializeCompressed emitted keys ParsePubKey rejects. fuzzEphemeralPrivateKey fuzzed the public half and D independently, so the two halves never agreed and IsKeyMatching would reject every key it made. The tbtc DepositSweepProposal generator produced unbounded reveal blocks where Marshal requires IsUint64. Assert the discarded errors, derive both key halves from one normalized scalar, and clamp reveal blocks in a local generator rather than narrowing the shared big.Int generator. Rename FuzzUnmarshaler to AssertUnmarshalDoesNotPanic so its name matches the only thing it checks.
shouldSkipElectrumIntegrationError matched three substrings of err.Error(), so rewording an upstream message silently turned a skipped integration test into a passing one, and an unrelated error whose text merely mentioned a timeout was skipped. Match errors.Is against goelectrum.ErrTimeout, wrappers.ErrRetryTimeout and electrum.ErrFeeEstimateUnavailable. Document both new sentinels on the variable and on the function that returns them, so depending on their identity is a stated promise rather than an accident. Regression tests cover bare, wrapped and doubly wrapped sentinels plus the two negative cases that guard against over-skipping.
Two electrum tests ranged over a fixture map with no presence check, so deleting a fixture made them run zero subtests and pass. The scenario loaders behave the same way: filepath.Walk skips absent files and returns a shorter slice with a nil error, so a consuming test loops zero times and reports success. Add an explicit manifest of required fixtures per directory and a guard that fails when one is absent. Each guard lives in the consuming package, never under testdata, because go test excludes that directory from ./... and a guard placed there would never run.
Several tests passed regardless of the behavior in their own title. TestContextCancelation claimed to verify that goroutines stop on cancellation but only called three methods and asserted nothing; it now runs observeSystemMetrics directly and fails if it does not return. TestLocalSubmitRelayEntry checked only that no error came back, so an implementation that validated its input and discarded it would pass; it now asserts the entry is readable afterwards. Replace 22 sleeps in the scheduler tests with channel synchronization and bounded polling that fails on timeout, cutting the package from 4.6s to 0.8s. Keep a real observation window where the assertion is that nothing happens, since proving a negative needs one. Split the two longest tests, 683 and 677 lines against a repo median of 33, into behavior-named functions with the same case counts.
The repo had no func FuzzXxx(f *testing.F) targets, so every fuzzed input came from a fixed generator and nothing was kept between runs. Add round-trip targets for the two paths whose generators were found broken: ephemeral key marshaling and the deposit sweep proposal. Both assert equality after the round trip rather than mere absence of a panic, which is what makes them able to catch the original bugs. Seeds cover the empty input, small values and the top of each accepted domain.
The two authorization suites each repeated the same two test bodies 25 times under different describe contexts. The repetition was contextually correct, but fixing one assertion meant editing it 14 times. Move the shared bodies into behavior functions invoked per context, passing the fixture through a getter so each test reads the instance created by its own beforeEach rather than a stale reference captured at module load. Test counts are unchanged at 118 and 144.
…appened assertNoValueChange treated any send on tw.iterated as proof the worker had run after being stopped. workerFunc increments the counter and sends on the channel as two separate steps, so a worker that incremented before the stop can deliver its signal after it. At -count=20 this failed while reporting an identical value on both sides of the comparison, which is a false positive. Use the counter as the source of truth and treat the signal only as a reason to re-check early. The package now passes at -count=20 in 16.8s against 30.7s for the original sleep-based version, and at -count=50. Also correct both native fuzz target comments. They claimed to catch the generator bugs that motivated them, but each target builds its own input and never calls FuzzFuncs, so neither would fail if a generator regressed. The comments now name the tests that do guard the generators and state what the targets actually cover.
The `describe.skip` on "when a contract gets upgraded during DKG" carried a two-part rationale and both parts are now stale. The fixture does accept `useAllowlist: false` as an explicit option, and the packaged TokenStaking artifacts do still expose `stake` and `increaseAuthorization`. Removing the skip restores "keeps data of the existing wallet" and "stores data of a new wallet". Both fail when mutated: swapping the expected public key and the expected members hash takes the file from 19 passing to 17 passing and 2 failing. The ecdsa suite is 836 passing with no pending tests and no remaining skips.
Keep Testnet fixtures required through the default manifest test while allowing the integration suite to skip Mainnet and Testnet4 when those networks have no vectors. Restore the justified G404 suppression for non-security backoff jitter.
## Summary Follow-up to #4256 that fixes all 13 confirmed review issue groups: 1. serve client metrics and diagnostics from a private mux so pprof stays disabled unless explicitly enabled 2. restrict the ECDSA workflow token to read-only permissions 3. use one buffered fee-floor invariant for proposal leaders and followers 4. reject a zero SPV proof-header limit whenever the SPV maintainer will run 5. validate every effective Electrum primary and fallback URL before dialing 6. redact Electrum URL credentials from validation errors and every URL-bearing log path 7. reject negative wallet transaction fee settings instead of silently ignoring them 8. guard the redemption per-request fee-cap multiplication against uint64 overflow 9. run the bundled Beacon export freshness check for every package or bundle change 10. construct follower fee-buffer arithmetic with big.Int before addition can overflow 11. give each ESLint policy process unique fixture paths 12. remove ESLint policy fixtures on normal completion, SIGINT, and SIGTERM 13. correct the malformed DKG key recovery comment to describe the former stalled round ## Verification - `go test -timeout 15m ./...` - `go test -race -timeout 3m -count=1 ./pkg/bitcoin/electrum ./config github.com/checksum0/go-electrum/electrum` - `go vet` - `staticcheck -checks=-SA1019 ./...` - `gofmt -l .` - `corepack yarn lint:ts` in `solidity/ecdsa` - `actionlint -ignore 'SC2086' .github/workflows/contracts-ecdsa.yml .github/workflows/contracts-random-beacon.yml` - two concurrent `yarn lint:eslint-policy` runs - SIGINT cleanup smoke: exit 130 with no fixture files left behind
Align the new and changed comments with the code they describe: - internal/testdata/bitcoin/manifest.go: the integration tests now skip (presence check) when a network has no Transactions entry, so the RequiredTransactions doc no longer claims they range the map without a check - pkg/bitcoin/electrum/electrum.go: EstimateSatPerVByteFee and ErrFeeEstimateUnavailable docs now state that the returned error wraps the last target's error, so the sentinel matches only when the last failure was an oracle -1 - solidity/ecdsa/test/Allowlist.test.ts: the two reverting cases are in the initialization group, not below it - drop previously/now diff narration from the wrappers, generator, pbutils, and electrum skip-classifier comments, keeping the durable invariants they document
P1: - add missing permissions block to contracts-random-beacon.yml (F-01) - document redemptions overflow-fallback semantic change (F-03) - declare EnableServer pprof-disabled breaking change in godoc (F-04) P2: - drop redundant Maintainer.Validate() call in maintainer.Initialize since spv.Initialize still validates at the use-site boundary (F-05) - correct Maintainer.Validate() godoc: it validates Spv, not 'all modules' (F-06) - document the dormant net/http/pprof DefaultServeMux side-effect in the clientinfo package doc and point registerPprofHandlers at it (F-07) - remove the redundant double error wrapper in maintainer.Initialize (F-09) P3: - reword DKG malformed-key comment to lead with current behavior rather than past-tense framing (F-10) - rename the redemptions overflow test case to reflect the branch actually exercised (fallback-to-txMaxTotalFee, not wrap-to-zero) (F-12) F-11 (replace sanitizeServerURL with (*url.URL).Redacted()) was reviewed and skipped: Redacted() keeps the username (only masks the password), which leaks more than the manual strip-everything implementation currently in place; the manual version is intentionally more conservative for Electrum server credentials. Kept as-is.

#4342) Follow-up to the merged PR #4338. This addresses all P1, P2, P3 findings raised by the multi-lens validated review of #4338. ## Summary Fixes all valid issues identified by the validated multi-agent review of the original #4338 PR, which covered a defensive security/reliability fix-up. This commit applies the remaining actionable findings that #4338 did not address. ### P1 - F-01: add missing `permissions: contents: read` block to `contracts-random-beacon.yml` (the original #4338 added it only to `contracts-ecdsa.yml`, despite the beacon workflow using the same `secrets.CI_GITHUB_TOKEN` for `notify-workflow-completed` and the same `yarn up` pattern). - F-03: document the new redemptions overflow-fallback semantics in code. When `txMaxFee * requestCount` overflows, the old code wrapped to 0 and rejected every estimate; the new code falls back to `txMaxTotalFee`. This semantic change is intentional (covered by the "huge per-request cap" test) but was not called out in #4338's PR body. - F-04: declare the `EnableServer(port int)` backwards-incompatible breaking change in godoc. The previous implementation implicitly exposed pprof via `http.DefaultServeMux`; the new implementation calls `enableServer(port, false)` and unconditionally disables pprof. No in-repo callers; external consumers would silently lose pprof functionality. ### P2 - F-05: drop the redundant `Maintainer.Validate()` call in `maintainer.Initialize` since `spv.Initialize` still validates at the use-site boundary. Reduces 3 identical validation passes per command to 2. - F-06: correct `Maintainer.Validate()` godoc — it currently validates only Spv, not "all modules" as the docstring claimed. - F-07: document the dormant `net/http/pprof` DefaultServeMux side-effect in the clientinfo package doc and point `registerPprofHandlers` at it. The current code builds a private ServeMux so the registration is dormant, but any future contributor adding a nil-handler `ListenAndServe` call would silently expose pprof. - F-09: remove the redundant double error wrapper in `maintainer.Initialize` ("cannot validate spv maintainer config: cannot validate spv maintainer config: ..."). ### P3 - F-10: reword the DKG malformed-key comment to lead with the current behavior (mark sender inactive so the protocol can continue) rather than past-tense framing. - F-12: rename the "huge per-request cap does not wrap to zero" test case to "huge per-request cap falls back to txMaxTotalFee" — the new code's *skip* branch is what's exercised, not a multiplication overflow that wraps to 0. ### Skipped - F-11 (replace `sanitizeServerURL` with `(*url.URL).Redacted()`) was reviewed and skipped: Go 1.15+ `Redacted()` keeps the username (only masks the password), which leaks more than the manual "strip everything" implementation currently in place. The manual version is intentionally more conservative for Electrum server credentials and was kept. ## Verification - `gofmt -l .` clean - `go vet` clean - `go build ./...` clean - targeted tests pass: - `go test ./pkg/maintainer/...` ok - `go test ./pkg/clientinfo/...` ok - `go test ./pkg/bitcoin/electrum/...` ok - `go test -run TestApplyWalletTxFeePolicy ./pkg/tbtc/...` ok - `go test ./pkg/tbtcpg/...` ok - `go test -run TestGenerateSymmetricKeys ./pkg/tecdsa/dkg/...` ok - `go test ./config/...` ok ## Related - Fixes all remaining actionable findings from the multi-agent-review orchestrator's validated review of #4338 - Original PR: #4338 (merged at commit 847e717)
## Description Automate the client benchmark regression check and make its baseline selection match the event that triggered the workflow. The benchmark job now runs for pull requests, pushes, scheduled runs, and manual dispatches instead of relying on a manually seeded `main` artifact. This also updates the BLS threshold-recovery benchmark to the production random-beacon workload: 33 shares from a 64-member group. It reports measured p50, p95, and p99 latency, with at least 100 observations so p99 is not derived from an undersized sample. No production BLS implementation changes are included. ## Changes - Select benchmark baselines by branch and event: - pull requests use the target branch's latest successful push artifact - scheduled and push runs use the current branch's latest successful push artifact - manual runs use the selected ref's latest successful manual artifact - Search older successful workflow runs until a matching `go-bench` artifact is found. - Skip comparison only when no matching artifact exists; unexpected download or API failures still fail the job. - Report newly introduced benchmark metrics that do not yet have a baseline. - Keep the existing statistically significant regression threshold of greater than 12%. - Run `BenchmarkThresholdVerify` with the production 33-of-64 beacon configuration. - Report p50, p95, and p99 latency from at least 100 per-operation samples. ## Measured BLS baseline Pinned measurement protocol: Go 1.24.1, prebuilt test binary, `GOMAXPROCS=1`, CPU 0, `-test.cpu=1`, ten 2-second repetitions, `schedutil` governor. | Metric | Median | IQR | | --- | ---: | ---: | | `ns/op` | 2.519979 ms | 2.512109-2.528706 ms | | p50 | 2.490060 ms | 2.480262-2.494987 ms | | p95 | 2.679569 ms | 2.658463-2.717255 ms | | p99 | 2.912661 ms | 2.825508-3.053553 ms | | Derived single-worker throughput | 396.83 ops/s | - | | Allocation bytes | 371,453 B/op | 371,453-371,453 B/op | | Allocations | 9,204 allocs/op | 9,204-9,204 allocs/op | The throughput figure is derived from reciprocal latency. It is not a loaded-service throughput measurement. ## Baseline behavior A pull request artifact does not seed its target branch. If the target branch has no successful push artifact yet, the comparison is skipped with a notice. The first successful push run on that branch establishes the baseline. First-seen metric units are also reported and start gating after a qualifying baseline exists. ## Verification - `GOTOOLCHAIN=go1.24.1 go test -timeout 15m ./...` - 60 packages passed - `GOTOOLCHAIN=go1.24.1 go vet ./pkg/bls` - `GOTOOLCHAIN=go1.24.1 go test ./pkg/bls -run '^$' -bench '^BenchmarkThresholdVerify$' -benchmem -benchtime=5x -count=1` - `/home/debian/bin/actionlint -ignore 'SC2086|SC2046' .github/workflows/client.yml` - `promtool check config prometheus.example.yml` - `promtool test rules rules.test.yml` - `git diff --check` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Chores** * Benchmark checks run for scheduled, manual, pull request, and push events, using a relevant prior run as the comparison baseline. * For tag builds, the current commit is used for baseline lookup. If no baseline is available, the check reports that comparison was skipped and still provides benchmark metrics, including latency percentiles. * Existing regression checks continue to flag slowdowns greater than 12%. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
- align validateMaintainerConfig with the library maintainer.Config.Validate conditional rule so a disabled-SPV setup is not rejected on an unrelated zero maxProofHeaders - extend spv.Config.Validate to reject zero/non-positive HistoryDepth, TransactionLimit, and backoff times: the flag defaults only cover omission, and each of these values silently degrades the maintainer at runtime the same way a zero MaxProofHeaders bound did - harden the clientinfo live-server tests: reserve an OS ephemeral port instead of the fixed 9799, following the cmd/maintainer_test.go pattern - add /profile and /trace to the enabled-path pprof endpoint assertions - warn when EnablePprof is set without a Port so the misconfiguration is not silently ignored - cover custom positive maxProofHeaders values through the flag -> config -> validation path - correct the stale DefaultServeMux comment in cmd/maintainer_test.go - document who merges sub-PRs into dev in docs/release-process.md
…4339) Three fixes found while reviewing the cumulative `dev` → `main` diff in #4256. Each was verified against `dev` before being fixed; both behavioral changes have a regression test that fails without the fix. ## pprof exposed while disabled `EnablePprof: false` did not disable profiling. Importing `net/http/pprof` registers `/debug/pprof/*` on `http.DefaultServeMux` from that package's `init`, whether the import is blank or named. `EnableServer` built an `http.Server` with a nil `Handler`, so it served `DefaultServeMux` and exposed the profiling endpoints on the client info port regardless of the setting. Reproduced before fixing: `GET /debug/pprof/` against the existing port-9799 test server returned `200` while profiling was disabled. Impact is bounded by whether the client info port is reachable. Where it is, a caller gets goroutine and runtime introspection plus the expensive `profile` and `trace` endpoints, and an operator who explicitly disabled profiling is silently overridden. To be precise about scope: Go's heap profile reports allocation metadata and stacks, not arbitrary process memory, so this is not a key-material dump. The handler is now built on a mux created per registry, with the pprof handlers registered only when profiling is enabled. That also removes a latent panic: registering the registry's routes on the process-global mux made a second registry fail with a duplicate-pattern conflict. `EnableServer(port int)` keeps its signature and never exposes profiling; `Initialize` calls a private `enableServer(port, cfg.EnablePprof)`. No exported API change. ## `--spv.maxProofHeaders 0` silently disables SPV proving The flag uses cobra's `UintVar`, which accepts `0`, and nothing validated the parsed value — the `144` default only covers omission. `getProofInfo` compares the running header count against the bound at loop entry with the count starting at zero, so a zero bound returns `proofSkipExceededMaxHeaders` on the first iteration for every transaction. SPV proving stops entirely while the logs report each transaction as possibly permanently unprovable, which reads as a chain condition rather than a misconfiguration. Rejected at startup rather than normalized to the default, so an explicit operator instruction is not silently replaced. Validation runs via `validateMaintainerConfig`, the first statement in `maintainers()`, before any chain connection is attempted. ## Documentation corrections `docs/release-process.md` described sub-PRs merging into `dev` *and* `main` before closing. If they also landed on `main`, the aggregation PR's diff would be empty and there would be nothing to release, contradicting the adjacent text describing that diff as what is queued for the next release. The `maxWalletTxVsize` comment called 10M vbytes "~2x Bitcoin block weight". A block is capped at 4,000,000 weight units, which is 1,000,000 vbytes, so the bound is ~10x a maximum block's vsize; the original also conflated vbytes with weight units. The bound itself is unchanged. ## Verification Run locally — not a full-repository suite, and CI has not been observed: - `go build ./...` - `go vet` on `pkg/clientinfo`, `pkg/maintainer/spv`, `pkg/tbtcpg`, `cmd` - `go test` on `pkg/clientinfo`, `cmd`, `pkg/maintainer/...`, `pkg/tbtcpg`, `pkg/tbtc` Tests added: pprof disabled (404 on the real server mux) and enabled (200 via `serverHandler(true)`); `Config.Validate` rejecting zero; and the command-level flag path asserting `--spv.maxProofHeaders 0` parses into config and is then rejected. `pkg/clientinfo` was run serially — its `TestMain` binds a fixed port, so concurrent runs can cross-talk. ## Scope These are the findings confirmed from a partial review of #4256; the review did not cover the whole aggregation diff, so this PR is not evidence that the rest of it is clean. Pre-existing issues unchanged by #4256 (the `latest` tag in `tbtc-v2-monitoring`, `thresholdnetwork` references in `scripts/build.sh` and the docker sample) were deliberately left alone.

* R1 - artifacts split: client-build-artifacts (runtime image,
multi-arch binaries, archive, GCR publish/notify) moved out of the
PR critical path; integration tests and the bench job no longer
wait for it. GCR publish/notify gating unchanged.
* R2 - 2-way shard + merged coverage gate: client-go-tests matrix
with fail-fast:false (shards 1 and 2 each build/load the
go-build-env image and run a deterministic half of the package
list); client-build-test-publish stays the required-check context
and becomes an aggregator that downloads both shard coverage
profiles, merges them (set-union, hosts 'go tool cover -func'
from setup-go@1.24), and enforces the existing 14% total gate.
Required context fails if any shard or the gate fails.
* R3 - rolling per-branch buildx cache: PR runs restore-only via
actions/cache/restore (key prefix per base-ref) so ephemeral PR
refs never save; push/schedule/dispatch save a versioned rolling
key with run_id so concurrent saves never collide. Legacy per-SHA
keys remain in the restore chain.
* R4 - PR-only cancel-in-progress concurrency on client.yml and
contracts-{ecdsa,random-beacon}.yml (per-run-id groups otherwise).
* R5/D4 - client-bench: comparison always runs; the >12% regression
exit is hard on push-to-dev, schedule, and workflow_dispatch,
advisory on pull_request (warning + job summary + PR comment,
check reports success). Push-to-main is not re-gated because the
dev push gate already catches the regression.
* R8 - if:always() aggregator gate job in each affected workflow
(client-gate, contracts-gate-ecdsa, contracts-gate-random-beacon)
closes the fail-open edge in finding 11: it FAILS unless
detect-changes succeeded AND every gated job succeeded, or was
skipped only because the path filter was 'false' on a pull_request.
On non-PR events every gated job must succeed. The required-check
context swap to the gate jobs on protected main is time-gated by
decision D2; the original required contexts stay in place.
## Summary
Implements the keep-core branch of the CI-speed plan on `dev`. Main
promotion and the required-check swap to the gate jobs are time-gated by
decision D2; the security-copy ports of R1/R2/R8 wait for this PR's
validation (plan §"Branch porting").
Public (`threshold-network/keep-core`) `main` is protected with the 7
required contexts listed below; this PR does not change branch
protection or the required-check settings — only `dev` is affected.
## Per-item changes (plan ids)
### R1 — `client-build-artifacts` moved off the PR critical path
`client-build-test-publish` no longer runs the runtime image build,
multi-arch binary build, archive step, GCR publish, or CI notify. They
move into a new `client-build-artifacts` job that consumes the same
`go-build-env-image` artifact and the rolling buildx cache. GCR publish
and CI notify keep their original `workflow_dispatch`-only gating. The
integration tests and the bench job no longer wait for the
binaries/archive, and the artifacts job runs in parallel with the rest
of the test pipeline. A failure here still red-lights the run.
### R2 — 2-way shard `Run Go tests` + merged coverage gate
- New matrix job `client-go-tests` (`fail-fast: false`, `[1, 2]`)
replaces the single in-job `go test ./...` step. Each shard runs a
deterministic half of the sorted package list (`go list ./... | LC_ALL=C
sort`, `sed -n start,end p` by index) in the same `go-build-env` image,
with its own `-coverprofile=/coverage/coverage.out`, and uploads its
profile as `go-coverage-shard-N`.
- `client-build-test-publish` keeps the original required-check name and
becomes an aggregator: it `needs` `client-detect-changes` and the matrix
`client-go-tests`, downloads both shard profiles, merges them into one
`coverage/coverage.merged.out` (set-union; the shards' per-package
blocks do not overlap because the split is disjoint), and runs `go tool
cover -func` on the merged profile. The existing 14% total-coverage gate
is applied to the merged total — same threshold, same logic, host Go
(`actions/setup-go@v5` `go-version-file: go.mod`). The required context
fails if any shard fails or the gate fails.
- Image production is hoisted to a new `client-build-image` job (must
run before the shards; the shards download the `go-build-env-image`
artifact and `docker load` it). This is the version of R2 that avoids
the cycle a pure "run shard 1 + merge" approach would have between
`client-build-test-publish` and shard-2 waiting for the image; explained
in the PR description.
### R3 — Stable per-branch buildx cache, no run_id in the key
- Save key: `<os>-buildx-<ref_name>-<deps-hash>-<sha>` (immutable,
`actions/cache/save@v4`, no `restore-keys`), where `<deps-hash>` is the
first 16 hex chars of `sha256(Dockerfile, go.mod, go.sum,
third_party/**/go.mod, third_party/**/go.sum)` (found recursively —
`third_party/*/go.mod` alone misses the two-levels-deep
`third_party/btcsuite/btcec/go.mod`), computed fresh each run by a
`Compute buildx deps hash` step. GitHub cache entries are immutable, so
`github.sha` is the per-push update suffix on top of the stable
`<ref_name>-<deps-hash>-` prefix — this refreshes the cache on every
source change without reintroducing run_id-per-run churn.
- **Save is the last step in `client-build-image`, placed immediately
after a successful `Move cache`, not combined with restore.** The
restore step (`actions/cache/restore@v4`) runs first, `if: always()`, on
every event. The save step (`actions/cache/save@v4`) runs only `if:
github.event_name == 'push' || github.event_name == 'workflow_dispatch'`
— and, because GitHub Actions implicitly ANDs a custom `if:` with
`success()` unless a status-check function is used, it is also skipped
if any prior step (build, move) failed. This avoids the failure mode of
a combined `actions/cache@v4` step placed *before* the build: that
variant restores at step-start but saves via a post-job hook that fires
regardless of later step outcomes, so a failed build/move could publish
the stale, pre-build restored layers under this run's immutable sha key
— a dead cache entry with no way to correct it afterward, since sha keys
never repeat.
- Restore-keys, most-to-least specific:
`<ref_name-or-base-ref>-<deps-hash>-` → `<ref_name-or-base-ref>-` →
legacy per-SHA `<os>-buildx-<sha>` → generic `<os>-buildx-`. On
`pull_request` the branch component is the PR's **base ref** (so PRs
read the target branch's pool, never their own ephemeral ref); on all
other events it is `github.ref_name`.
- `client-build-artifacts` (the second buildx consumer in a run) is
restore-only on every event using the identical key/restore-keys chain —
exactly one job (`client-build-image`) ever saves.
- **Note on the `push` trigger:** `client.yml`'s `push` trigger
(unchanged by this PR) already includes both `main` and `dev` (see the
`on:` block), so ordinary pushes to `dev` *do* seed/refresh the `dev`
cache pool automatically — no special-casing was needed to cover `dev`
pushes. `workflow_dispatch` is included in the save condition as a
second, manually-triggered writer (e.g. for warming the pool once after
this PR lands, before the first organic `dev` push, or for an on-demand
refresh) — not because `push` excludes `dev`. Run **one manual
`workflow_dispatch` of `Client` on `dev`** after this PR lands to
populate the pool immediately under the new key format rather than
waiting for the next organic push.
### R4 — `concurrency` (PR-only cancel-in-progress)
Workflow-level on `client.yml` and `contracts-ecdsa.yml` /
`contracts-random-beacon.yml`:
```yaml
concurrency:
group: ${{ github.workflow }}-${{ github.event_name == 'pull_request' && github.event.pull_request.number || github.run_id }}
cancel-in-progress: ${{ github.event_name == 'pull_request' }}
```
New pushes on the same PR number cancel the superseded run; main/dev
pushes and the nightly schedule never cancel a concurrent run.
### R5/D4 — `client-bench` is advisory on pull requests
- `Compare benchmarks` (new `id: compare`) always runs whenever a
baseline is found; it parses the benchstat diff and produces the
benchstat output (`benchstat-results.txt`).
- `Fail on benchmark regression` hard-fails only on pushes to `dev`, the
nightly `schedule`, and `workflow_dispatch` runs (`steps.compare.outcome
== 'success'` && event ∈ those). Pushes to `main` are not re-gated
because a regression can only reach `main` after passing the `dev` gate.
- `Report benchmark regression (advisory on pull_request)` only runs on
PRs; on a regression it writes a `::warning::` annotation and appends a
section to `$GITHUB_STEP_SUMMARY` so reviewers see it on the PR page.
The check still reports success.
- `Post benchmark results to PR` keeps its original comment behavior.
### R8 — `if: always()` aggregator gate jobs (closes the fail-open edge)
Added `client-gate`, `contracts-gate-ecdsa`, and
`contracts-gate-random-beacon` jobs. Each:
- `if: always()` — runs even when downstream jobs are skipped, so the
gate verdict is reached.
- `needs: [detect-changes, ...gated jobs]`.
- Shell step:
- `client-detect-changes` must `success` on every event (closes the
dorny/paths-filter fail-open).
- For each gated job, the gate derives the "expected to run" condition
from that job's own `if:` directly: `client-build-test-publish` is
expected to run when `event != 'pull_request' || filter == 'true'`,
`client-scan` / `client-format` are expected to run when `event ==
'push' || filter == 'true'`. An expected-to-run job must be `success`; a
job that was not expected to run is fine as `skipped` (its own `if:` was
false) or `success`.
- Any `failed` result fails the gate regardless of expected-run.
- For the contracts gates the gated jobs (`contracts-build-and-test`,
`contracts-lint`, `contracts-deployment-dry-run`, `contracts-slither`)
all share the same `if:` (`filter == 'true' || event !=
'pull_request'`), so the same per-event rule applies; the contracts gate
already handled the schedule/dispatch case correctly because every gated
job runs on non-PR events.
This is exactly the dorny/paths-filter fail-open described in finding
11. Today the public `main` required checks still pass on the original
job names; the swap of
`client-build-test-publish`/`client-scan`/`client-format` →
`client-gate` and the 4 Solidity contexts to their gate jobs is
**time-gated by decision D2** and is intentionally NOT done in this PR.
Without that swap, this PR still fails closed on direct shard/coverage
failures (via `client-build-test-publish` failing), and R8 is in place
for the D2 swap.
Verified the new gate rule against every (event, path-filter)
combination: schedule and workflow_dispatch correctly accept
`client-scan`/`client-format` skipping; pull_request+filter=false
correctly accepts all three gated jobs skipping;
pull_request+filter=true requires all three to succeed;
`client-detect-changes` failure fails the gate regardless of event.
## Expected effects
Public client workflow p50 (per plan §"Baseline" → §"Top changes"):
- Image build + tests (R1+R2): 16.3m → ~9.5m (binary/runtime off the
chain, shards ~4m in parallel)
- Total wall (R1+R2): 26.9m → ~16-18m p50 (gate adds ~5s,
integration/bench/artifacts parallel)
- Cache churn (R3): stable `<ref_name>-<deps-hash>-<sha>` key, save only
on `push`/`workflow_dispatch` (one writer job); `pull_request` and the
nightly `schedule` are restore-only and never write — eliminates the
~31+ entries/month `schedule` alone was producing under the prior
always-save design.
- Bench (R5/D4): PRs no longer wait on the >12% regression; main pushes
not re-gated (dev gate suffices).
## Safety guardrails preserved
- All 7 required contexts (`client-build-test-publish`, `client-scan`,
`client-format`, `contracts-build-and-test`, `contracts-lint`,
`contracts-deployment-dry-run`, `contracts-slither`) keep their names
and continue to surface on every PR.
- Full suites still run on push to `main`/`dev`, on the nightly
schedule, on `workflow_dispatch`, and on every PR that touches the
relevant paths.
- The dorny/paths-filter stub pattern is preserved (no trigger-level
`paths:` conversion); only the new gate jobs are added.
- The `client-build-test-publish` aggregator fails if either test shard
fails or the merged coverage gate falls below 14% — the required check
is fail-closed against the sharding.
## Time-gated follow-ups (NOT in this PR)
- **D2 (required-check swap)**: on protected `main`, swap the 7 required
contexts to `client-gate` + `contracts-gate-ecdsa` +
`contracts-gate-random-beacon` (and the original jobs can be removed in
the same PR). Admin action; canary on `dev` first.
- **Security-copy ports**: R3/R4 are open on all four
`keep-core-security` branches in PRs #155-#158. R1/R2/R8 still wait for
this public PR's validation and the branch-specific rollout in the plan.
## Verification evidence
- First head: 34 checks passed, 9 skipped, and only `client-bench`
failed. The benchmark comparison itself found no >12% regression; the
advisory report step then raised `NameError: GITHUB_STEP_SUMMARY is not
defined`.
- Fix commit `e89bb6c62` reads `os.environ['GITHUB_STEP_SUMMARY']`. The
exact embedded Python step was smoke-tested with both a no-regression
benchstat and a +30% advisory regression: both exit 0, emit the expected
log/annotation, and write the expected job summary.
- Replacement attempt 1 then passed the benchmark path but exposed one
unchanged timing-sensitive test:
`TestRateLimiter_RequestsPerSecondLimitOnly/test_SubscribeNewHead`
measured 582.03 requests/s against the test's 575 ceiling. The test file
is byte-for-byte unchanged from `origin/dev`. Failed-job rerun attempt 2
passed in 20m19s: Go shards 1/2 and 2/2 finished in 7m19s and 7m24s,
integration in 10m54s, and the advisory benchmark in 11m53s. Final head
result: 35 success, 9 skipped, 0 failures.
- Coverage merge + gate verified locally with synthetic profiles in a
module named `github.com/keep-network/keep-core` (`go tool cover -func
merged.out` returns the expected total).
- `actionlint` on `client.yml` reports only the 8 pre-existing
shellcheck findings; `contracts-ecdsa.yml` /
`contracts-random-beacon.yml` retain their 6 pre-existing findings.
- Structural validation found exactly 2 `actions/cache/restore@v4` steps
and exactly 1 `actions/cache/save@v4`, placed after `Move cache`.
## Agent involvement
- Plan authored by Main.
- Implementation (R1/R2/R3/R4/R5/R8 in this repo, contracts gates,
dev-only branch) by subagent `KeepCorePublicImpl`.
- Validation done locally: YAML parses; matrix/shard strategy verified;
coverage-merge mechanics verified in a real module; cache-save/restore
pattern follows the orchestrator's rolling-key guidance; concurrency
group uses the documented `pull_request.number || run_id` pattern.
# Conflicts: # .github/workflows/client.yml
The Go 1.24 Docker builders reject dependency updates that require Go 1.25.7, including the IPLD update discussed in #3991. Raise the module minimum to 1.25.7 and use Go 1.26.8 for the suggested toolchain, both Docker builders, and CI. Go 1.26 is the older supported release line; Go 1.25 left support when Go 1.27 shipped. The source builder and runtime move to Alpine 3.23. The release builder retains Bullseye's C compiler and glibc 2.31, copying only Go from the official 1.26.8 image. This preserves cgo for native Linux/amd64 releases and compatibility with Debian 11 and Ubuntu 20.04. Both the client and tag-based release workflows now extract the actual Linux release archive and run the binary in both baseline containers before archiving or publishing it. All `setup-go` jobs use v6 and read `go.mod`, including the vendored btcec and manual benchmark jobs; v6 honors the `toolchain` directive. The benchmark job now checks out the repository to read that file. Staticcheck moves to 2026.1 for Go 1.26 support. This targets `dev` and implements the standalone toolchain step of #3991. All module dependency versions and `go.sum` remain unchanged; the issue's separate x/crypto, telemetry, and IPLD/libp2p reviews remain follow-ups. Validation: - The original PR's CI Linux release artifact fails at startup on both Debian 11 and Ubuntu 20.04 with missing `GLIBC_2.32` and `GLIBC_2.34` symbols, confirming that the added check detects the regression. - The updated Linux/amd64 builder reports Go 1.26.8, glibc 2.31, and `CGO_ENABLED=1`. - [CI on the final commit](https://github.com/threshold-network/keep-core/actions/runs/34245079426/job/102124924005) passes the full Go unit suite, coverage gate, Docker runtime build, Linux/macOS release packaging, and startup of the rebuilt Linux archive on both Debian 11 and Ubuntu 20.04. Formatting, vet, Staticcheck, gosec, and vendored btcec verification/tests also pass. - Workflow YAML, the compatibility step's Bash syntax, Go 1.26.8 formatting, and `git diff --check` pass. - The separate client integration job also passes. All applicable CI checks are green on `97b4e1ce5a26a6db467f322e619de059d844b61d`. References: [Go release policy and versions](https://go.dev/doc/devel/release), [Staticcheck 2026.1](https://staticcheck.dev/changes/2026.1/). --- ## Prepared rebase onto `dev` (not pushed yet) This branch conflicts with `dev`. A rebase onto `dev` at `bc4a10e` was prepared and verified locally: range-diff and net-diff were checked against the current head `97b4e1c`, all 3 commits are kept with identical line changes, and nothing from this PR was lost; both workflow YAMLs parse, `go build ./...` and `go mod tidy -diff` passed (actionlint and a Docker build were not run). It has not been pushed; the branch is unchanged. When pushed, the original head will be kept as `backup/codex/go-toolchain-3991-20260926`. **Judgment calls for review:** - Added commit `ci: align Go setup in electrum jobs added on dev`: `electrum-vendor-byte-identity` (setup-go@v5 pinned to 1.24.1) and `electrum-lifecycle` (setup-go@v5) landed on `dev` after this branch was cut. Both now use setup-go@v6 with `go-version-file: go.mod`, like every other job in this PR. They would likely still work without it (GOTOOLCHAIN=auto), so drop the commit if you prefer. - `client-bench` permissions: kept both sides, so the job has `actions: read`, `contents: read` (this PR, for its checkout step) and `pull-requests: write` (from `dev`'s #4340), followed by `dev`'s env block. _Generated by [Claude Code](https://claude.ai/code)_
