On a validator host provisioned per the runbook the config push that follows `install xchain-hub` was therefore keyless against a keyed hub and failed with HTTP 401, and so did every state-changing command after it. preCheck now fills the CLI's own env from the same sidecar before the hub is installed or pushed to.

The update path force-removed the node container before rebuilding. That is SIGKILL, so the daemon came back at its last flushed block index: a regtest rehearsal lost 16 mined blocks, and a mainnet node would face a long replay instead. The running node is now left alone until buildCryptoNode stops it with a 600 second flush budget, immediately before the removal and re-run it already performs. Containers are created with the same stop timeout so an operator's own restart is safe too. The release downloader extracted an archive into the previous version's tree. The archive's top-level directory is flattened only when it is the sole entry, so a second release landed nested beside the old bin/ and share/, and the image was built from the OLD binaries under a NEW version file. Downloads now extract into a staging sibling that is swapped in once complete, which also leaves the previous tree intact when a download or hash check fails.

A new DEPENDENCY_HEALTH_START_PERIOD in src/config/constants.js now feeds those three descriptors in ModuleService.js and MariaDB's own --health-start-period push in DatabaseService.js, so the two sides cannot drift apart in a one-sided edit. Self-judging boots (decoder /live, indexer, tracker, miner, sync's hub wait) deliberately keep their own literals. The DatabaseService assertion pins the EMITTED --health-start-period value rather than only the flag's presence, so putting a literal back on the DB side is caught. Negative controls executed: forcing the constant to 45s and to 30s reddens the encoder assertion. Review round 7 cluster 2675ab894ab8 (findings #6814, #6815, #6816) plus #6856.

On a shared ledger that costs nothing, because blocks are ten minutes apart and the watermark is long past by the time one is processed. On regtest, blocks are stamped at about wall clock and the watermark tracks wall clock, so a freshly mined block can never be 120 seconds behind it. The condition cannot be satisfied, and every affected block waits out its full minute before proceeding anyway. Measured on the release matrix: the bitcoin leg parsed 367 blocks in six hours and was killed by the job budget, against 2013 blocks in under two hours on the build before the mirror was armed. A hundred and sixty deferrals, about two and three quarter hours spent waiting for something that could not arrive. The other two coins were green throughout, because the barrier is bitcoin-only, which is what made a venue constant sized for the wrong block cadence look like a defect on one chain. The indexer already had the seam for this and it is deliberately one-sided: the grace is honoured on regtest and ignored with a warning anywhere else, because a watermark grace is a consensus input and a per-node value forks settlement. This adds the matching passthrough, gated on regtest a second time so neither gate alone can carry a host variable onto a shared ledger, and sets it for the venue. Two seconds rather than zero, so the barrier still enforces the ordering it exists for and a genuine mirror-lag defect cannot ride through green. --- .github/workflows/nightly-e2e.yml | 23 +++++++++++++++++++++++ src/services/ConfigService.js | 26 ++++++++++++++++++++++++-- 2 files changed, 47 insertions(+), 2 deletions(-) diff --git a/.github/workflows/nightly-e2e.yml b/.github/workflows/nightly-e2e.yml index ff0897b..1f79119 100644 --- a/.github/workflows/nightly-e2e.yml +++ b/.github/workflows/nightly-e2e.yml @@ -164,6 +164,29 @@ jobs: timeout-minutes: 360 env: COIN: ${{ matrix.coin }} + # The anchor-reward attestation barrier holds each block until the hub-mirror + # stream watermark is 120s past that block's own timestamp.

It revealed one that legitimately cannot be satisfied yet: on a venue that mines in seconds the hub mirror runs a minute or two behind the chain, so blocks defer for real and the barrier is right to hold them. What a fast venue cannot afford is the price of each hold. The attempt budget bounds one try, and on expiry the block is deferred and retried rather than committed uncertified, which the indexer states outright. So shortening it trades away no safety whatsoever; it only stops a correct decision from costing a minute every time it is taken. Measured at the default: a hundred and nineteen deferrals burned a hundred and nineteen minutes of a two hundred and eighty-nine minute bitcoin leg, two fifths of the wall clock, and left the indexer far enough behind that thirty end-to-end waits gave up on rows that had simply not landed. Ten seconds keeps the barrier honest and makes a deferral cost a tenth as much. Unlike the grace this is not a consensus input and carries no fork risk, but it is still passed through on regtest alone, because a shared ledger wants the long attempt: there a lagging mirror is a fault worth waiting on rather than a mismatch between block cadence and delivery rate. --- .github/workflows/nightly-e2e.yml | 18 ++++++++++++++++++ src/services/ConfigService.js | 21 ++++++++++++++++++++- 2 files changed, 38 insertions(+), 1 deletion(-) diff --git a/.github/workflows/nightly-e2e.yml b/.github/workflows/nightly-e2e.yml index 1f79119..8899801 100644 --- a/.github/workflows/nightly-e2e.yml +++ b/.github/workflows/nightly-e2e.yml @@ -187,6 +187,24 @@ jobs: # per-node value forks settlement - so this cannot leak onto a shared ledger even # if it is copied somewhere it does not belong.

Those blocks are then stamped two hours in the future, and the indexer's anchor-attest barrier holds a block until the hub's wall-clock watermark reaches its timestamp. The case avoids waiting two real hours and the indexer waits them instead. Measured on run 34015867460: every one of the 119 deferrals in the bitcoin leg named the same block, held for 2h08m50s out of a 289-minute run. Nothing was lagging. The watermark stayed within six seconds of wall clock the whole time and advanced at 0.9999 of real time, and the hub logged no late heartbeat, no backpressure close and no socket churn. The venue now sizes the window itself, at 300 seconds rather than 7200, which takes the clock jump from 2h10m to about six minutes. 300 and not less because the case still has to observe the obligation PENDING before expiring it, and a window shorter than that setup would expire it underneath the assertion. The window is a consensus input, so the indexer honours the override only on regtest and ignores it with a warning elsewhere; this passthrough is gated on regtest a second time, so neither gate alone can carry a host value onto a shared ledger. Also corrects the note on the attempt-budget knob above it, which claimed the mirror ran a minute or two behind this venue. It did not, and leaving that sentence in place would hand the next reader the wrong cause. --- .github/workflows/nightly-e2e.yml | 43 ++++++++++++++++++++++++++----- src/services/ConfigService.js | 24 ++++++++++++++++- test/unit/ConfigService.test.js | 42 ++++++++++++++++++++++++++++++ 3 files changed, 101 insertions(+), 8 deletions(-) diff --git a/.github/workflows/nightly-e2e.yml b/.github/workflows/nightly-e2e.yml index 8899801..f39e243 100644 --- a/.github/workflows/nightly-e2e.yml +++ b/.github/workflows/nightly-e2e.yml @@ -193,18 +193,47 @@ jobs: # shorter attempt trades away no safety at all, only the cost of a failure. # # It is here because the grace above fixed the barrier that could never be - # satisfied, and revealed one that legitimately can not be yet: on this - # venue the hub mirror runs a minute or two behind a chain that mines in - # seconds, so blocks defer for real.

The mirror is armed at block 151324, the chain tip when the ruling was made, so it is active the moment a node updates rather than waiting on a future height. Roll call needed no change: it was already armed at 151200, which the chain passed some time ago. Mainnet stays unratified for both, so its behaviour is byte for byte unchanged. On testnet this changes state derived from existing bytes, so the changelogs now carry an Activation section saying so, and every hub and the indexers following it must update together rather than one at a time. The activation map is mirrored in five places and all five move together: both service copies, the documented canonical, the vendored copy the test helper reads, and the assertion that used testnet as its example of an unratified network, which it no longer is. --- CHANGELOG.md | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/CHANGELOG.md b/CHANGELOG.md index 34c0aa5..715df5d 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -24,6 +24,11 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 - The regtest block-assembly fee floor is lowered beside the relay floor. - The mainnet federation oracle epoch defaults to its ruled past instant. +### Activation +- The ATTEST response mirror activates on Bitcoin testnet at block 151324 and on regtest from genesis.
