Each benchmark uses a dedicated node-db (mainnet-1 through mainnet-4), so there is no conflict. Removing max-parallel: 1 lets all 4 benchmarks run concurrently on separate bench runners.
The time -v measurement included cardano-node child process memory, reporting 11.4 GB when the wallet itself uses only 10-43 MB. Add self-RSS monitoring via /proc/self/status and GHC RTS stats reporting to the benchmark, and label the time -v figure clearly as including cardano-node.

Closes #5172 Closes #5181 Bump [cardano-node 10.5.4](https://github.com/IntersectMBO/cardano-node/releases/tag/10.5.4) runtime and dependencies. > **Note**: cardano-node 10.5.4 requires [libblst 0.3.14](https://github.com/supranational/blst/releases/tag/v0.3.14) when building from source. Our nix flake already pins this version. ### Changes - **cardano-node runtime**: 10.5.3 → 10.5.4 (`flake.nix`, `flake.lock`) - **CHaP index-state**: 2026-01-28 → 2026-02-05 (`cabal.project`) - **MonadEvaluate constraint**: ouroboros-network 0.21 changed `runPeer`/`Stateful.runPeer` to require `MonadEvaluate m` instead of `MonadThrow`/`MonadMask` — updated `Network.Implementation` accordingly - **Cleanup**: removed unused `mapMaybe` import in `FlakyTests.GHA`
Replace -L with --quiet and add --quiet where missing across all CI workflow files. This suppresses verbose nix build logs and warnings that clutter GHA output. Closes #5148, closes #5118
runPeer and Stateful.runPeer now require MonadEvaluate m after the ouroboros-network bump in cardano-node 10.5.4. MonadEvaluate implies MonadThrow and MonadMask, so those become redundant. Also fix: redundant mapMaybe import in FlakyTests.GHA, ambiguous foldl' in UTxOHistory.Model (GHC 9.12 Prelude).

- Rewrite updating-dependencies.md: replace stale Jörmungandr/Buildkite references with cardano-node bump, CHaP-only bump, and GHC bump sections - Add fourmolu migration ADR (2026-02-12) - Replace stylish-haskell with fourmolu in coding-standards.md and building.md - Mark 2023-01-27 CI decision as superseded - Add PR references to GHA migration ADR - Add missing entries to SUMMARY.md Closes #5173, closes #5174
## Summary - Remove `.buildkite/` pipeline configs - Remove `lib/buildkite/` Haskell package and references in `cabal.project` / `nix/project-package-list.nix` - Remove dead scripts: `scripts/buildkite/admin/`, `scripts/buildkite/windows/`, `cabal-ci.sh`, `hls-ci.sh` - Remove `windows-tls-diagnostic.yml` workflow (one-off diagnostic) - Remove `.claude/skills/buildkite/` skill - Clean up `.gitignore` buildkite comment Scripts still in use by GHA workflows (`scripts/buildkite/main/`, `check-haskell-nix-cabal.sh`) are kept. Closes #5175
Closes #5171 Closes #5176
## Summary - Replace stylish-haskell with fourmolu in CI script, justfile, and nix dev shells - Upgrade fourmolu to 0.19 (from nixpkgs-recent) for `import-grouping` support - Configure `import-grouping: by-qualified` in `fourmolu.yaml` - Reformat entire codebase (832 files) - Add `.git-blame-ignore-revs` for the reformat commit - Update contributor docs (coding-standards.md, building.md) - Fix contradictory `NoNumericUnderscores`/`NumericUnderscores` pragmas in SurplusSpec.hs Closes #5145
## Summary - Adds `LedgerDB.Backend: V1LMDB` to mainnet node config - Fixes Docker boot sync by setting `working_dir: /data` for the node container - Adds container log dumping on Docker boot sync failure for debugging ## Context V1LMDB is the recommended backend for edge nodes (wallets, explorers) — uses ~8GB RAM vs ~24GB for V2InMemory. Required for Mithril snapshot ledger states which use LMDB format. The Docker boot sync was failing because V1LMDB creates its database directory (`mainnet/db/lmdb/tables`) relative to CWD, which in the container pointed to a read-only path. Setting `working_dir: /data` ensures LMDB writes to the mounted data volume. ## CI All checks pass: https://github.com/cardano-foundation/cardano-wallet/actions/runs/21954112236
Without this, Docker boot sync failures are opaque — we only see "timeout" with no indication of why the node or wallet didn't start.
