Weekly Development Snapshot

QRL 2.0 Testnet V3 checklist from that update:

qrysm

Improved fork-choice and block-import recovery, preserving votes, finalization and execution validation across partial failures, cancellations and reorganizations
Fixed handling of skipped-slot checkpoints, duplicate blocks and state recovery when blocks disappear during reads
Improved state snapshot isolation and cache consistency, and released detached validator references to avoid retaining unused memory
Hardened deposit processing and execution RPC handling against malformed responses, failed batches and timeouts
Corrected SSZ encoding bounds and Merkle proof construction, and preserved signatures, deposit commitments and proposer slashings during copying and conversion
Fixed voluntary exits to load custom chain configuration, so exits use the correct network’s signing parameters
Added regression coverage for the fixes

qrl-tests

Added automated consensus and staking test suite, covering deposits, validator activation, attestations, voluntary exits and withdrawals on a live test network
Added the suite to nightly testing, with deposit waits derived from the live chain configuration and exits signed through the validator keymanager API

go-qrllib

Added an additional Falcon-1024 tests, covering randomized encoding and FFT operations, sampling, key derivation and signing
Included checks for architecture-sensitive key derivation; the upstream Falcon-1024 integration remains in review
Updated the upstream Codecov CI action to v7.1.1

rust-qrllib

Added ML-DSA tests confirming that signing fails after secret-key zeroization, repeated zeroization is safe, and the public key can still verify earlier signatures
Refreshed Rust crates, demo dependencies and CI action pins

qrypto.js

Updated development dependencies and CI action pins, including Mocha 12 and refreshed linting, formatting, build and browser-test tooling

QRL

qryptonight / qrandomx

Switched Linux builds to portable CPU targets, improving compatibility across x86-64 and ARM64 hardware
Preserved optimized Argon2 runtime selection in qrandomx while using the portable build baseline
Fixed source-distribution builds and version metadata; published pyqryptonight 0.99.13 and pyqrandomx 0.3.4

qrl-docker / qrl-docker-ci

Documented the portable CPU baseline and how operators can verify their images
Removed temporary compiler-wrapper workarounds from the Bionic and Focal images after the mining-library fixes became available
Added Clang 18 to the Noble CI image for ThreadSanitizer testing

qrl-v1-docker-cluster

Added a tool for running disposable QRL 1.x test networks across multiple Docker images
Checks node health, mining, agreement on block hashes, wallet persistence and CPU instruction compatibility, then saves a report and logs
