xchain-e2e-test v0.20.0

xchain-e2e-test v0.20.0, part of the XChain Platform v0.20.0 train.

The suite adds acceptance coverage for the mirror-admission and anchor-attestation
barriers across live, replay, flag-day, parity and second-chain cases, plus end-to-end
token-bridge and policy-inheritance rails for regtest. Each chain uses its own fee
destination, DOGE cross-settle setup follows the disclosed mirror topology, and
bridged-gas drills resolve and wait for the hub relay margin while both chains idle-mine.
Barrier waits are state-based, replay rows containing BigInt values serialize safely, and
the drills follow the relocated writer-leg resolver. Database helpers no longer expose
the unused sqlPath field.

xchain-e2e-test v0.19.0

xchain-e2e-test v0.19.0, part of the XChain Platform v0.19.0 train.

The settle path is drilled across the hub and indexer canonicals, signing with one and
verifying with the other, and the full distribution rail is drilled from a mint through a
lock to an airdrop. Gas is funded off Bitcoin by bridging instead of issuing locally, since
a broadcast gas issue is refused off Bitcoin, and every direct gas mint is routed through a
chain-aware helper with helper ticks lifted above the namespace floor. The full bitcoin leg
of this suite on the release branch is the train's structure-pass proof: its action suites
registered at the measured baseline (273 passing, 32 pending, 0 failing). Restructured
under the platform code-structure standard (feature directories, snake_case files, split
test suites, restored comments).

xchain-e2e-test v0.18.0

xchain-e2e-test v0.18.0, part of the XChain Platform v0.18.0 train.

XChainHubConnector cross-checks the hub-served coin consensus hashes against the
vendored registry and logs any disagreement. The field round-trip golden vectors are
regenerated from the indexer-derived encoding and alias discovery is fixed, clearing three
pre-existing failures.

xchain-e2e-test v0.17.0

xchain-e2e-test v0.17.0, part of the XChain Platform v0.17.0 train.

The AT5 oracle barrier drill grades live blocks against the barrier's own inputs and clock,
aligns verdicts on tx_hash, and stops on verdict comparisons rather than block count. A
federation drill drives a degraded ARCHIVE attestation round across two validators, and
anchor acceptance targets the v0 bundle with the v1 archive head. Every deployed contract
fixture carries meta for the CONTRACT_META_REQUIRED flag day, and the seed contract pin
moves to its new hash.

xchain-e2e-test v0.16.0

xchain-e2e-test v0.16.0, part of the XChain Platform v0.16.0 train.

Drills for the zero-confirmation attestation flip (serve at the tip, re-mine, headroom, applier fall-through, flag day) and a roll-call gates drill that publishes v1 roll calls and checks the rules-aware attestation set; a venue tool that ages a stale roll-call absence out of the streak window; the roll-call venue refuses epochs the DOGE side already holds rows for; npm run stage:siblings stages the sibling SDK and hub checkouts for the SDK suites; native-fee price seeds survive an indexer reset. The staged hub and SDK snapshots record 0.16.0.

v0.15.0

xchain-e2e-test v0.15.0, part of the XChain Platform v0.15.0 train.

This train adds acceptance suites for the two new consensus mechanisms: an ATTEST response-mirror venue running real hubs and mirror-fed indexers through fault injection and a set of admission-cap drills, and a ROLLCALL venue driving eviction, rollback and cooldown re-entry on a shared two-chain regtest network. Fixture stakes are now released when a run ends, and the suite can fail a run that leaves capability or staking keys behind in the shared venue.
