- Add faucet_accounts support to cluster.toml for pre-funded test accounts
- Update init.sh to inject faucet accounts into genesis.json
- Fix start.sh process check to work on macOS (use kill -0 instead of /proc)
- Update MANUAL.md with prerequisites, build instructions, and benchmarking guide
- Add default faucet account to single_node and four_validator cluster configs

These changes enable running gravity_bench against local clusters without
manual genesis modification.
- Split single test job into 5 parallel jobs: test-core, test-consensus,
  test-aptos, test-dependencies, test-binaries
- Run heavyweight jobs (clippy, build, tests) in Docker containers for
  cleaner environment and better disk space management
- Add intermediate cleanup steps (cargo clean) between large test runs
- Run memory-intensive tests serially (--test-threads=1)
- Add rust-ci.Dockerfile for custom CI image (clang, llvm, Rust 1.88.0)
- Add build-ci-image.yml workflow for auto-building CI image
- Temporarily use rust:1.88.0-bookworm until custom image is published

- Remove container to run directly on runner
- Clean up .NET, Android SDK, CodeQL, Docker images before build
- Install Rust 1.88.0 directly on runner

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove container usage for all jobs
- Add disk cleanup step (remove .NET, Android, GHC, CodeQL, Docker images)
- Use rustup default 1.88.0 instead of container

Split the 1h+ test-aptos job into parallel jobs:
- test-aptos-consensus-types (11 tests)
- test-aptos-safety-rules (10 tests)
- test-aptos-mempool (1 test)
- test-aptos-dag-network (23 tests)

This allows tests to run in parallel, reducing total CI time.

- rust-ci.yml: Switch all tests to --release mode for faster builds
- nightly-tests.yml: New workflow running debug mode tests daily at 2AM UTC

Release mode benefits:
- Smaller build artifacts = better cache hit rate
- Faster test execution
- Closer to production behavior

- Merge 6 separate test jobs into 1 unified job to avoid redundant compilation
- Update rust-ci.Dockerfile to pre-compile dependencies in image
- Update build-ci-image.yml to trigger on Cargo.lock/Cargo.toml changes
- Remove migrated-tests.yml (merged into rust-ci.yml)

Benefits:
- Compile once, run all tests (vs compile per job before)
- Pre-compiled deps in Docker image speeds up builds
- rust-cache preserves target/ between runs for incremental builds

CI Improvements:
- Merge test jobs into single unified job to avoid redundant compilation
- Add pre-compiled Docker image for faster builds
- Update build-ci-image.yml to trigger on Cargo.lock changes

Test Fixes:
- Fix 45 aptos consensus tests (DAG, safety-rules, network tests)

The pre-built Docker image ghcr.io/galxe/gravity-sdk/rust-ci:latest
doesn't exist yet. Fall back to rust:1.88.0-bookworm with manual
dependency installation.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Update rust-ci.yml to use ghcr.io/${{ github.repository }}/rust-ci:latest
so each fork can build and test its own pre-compiled image.

Next steps:
1. Manually trigger "Build CI Docker Image" workflow
2. After image is built, CI jobs will use the pre-compiled image

The external/gravity_chain_core_contracts/genesis-tool/ directory
is not tracked in git, causing Docker build to fail.

Cargo.toml references benches/safety_rules.rs which needs to exist
for cargo fetch to work.

Remove pre-compilation from Docker image due to GitHub Actions runner
disk space constraints. The image now only:
- Installs system build dependencies (clang, llvm, etc.)
- Sets up Rust environment with nightly rustfmt

Pre-compiled artifacts will be cached between CI runs using the
rust-cache action instead of baking them into the Docker image.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove container usage from clippy, build, test jobs
- Add disk cleanup step to free ~20-30GB (remove .NET, Android SDK, etc.)
- Install system dependencies directly on runner
- Keep rust-cache for compilation caching

This approach avoids disk space issues without needing a pre-compiled
Docker image.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Stage 1 (builder):
- Compile all dependencies in release mode
- Aggressive cleanup: remove incremental cache, fingerprints, etc.
- Keep only .rlib files

Stage 2 (final):
- Copy cargo registry (downloaded sources)
- Copy cleaned release deps (~small)

This should fit within disk limits while providing pre-compiled deps.

Remove references to files that don't exist in the repo:
- crates/gravity-storage/Cargo.toml
- crates/gravity-primitives/Cargo.toml
- crates/api-types/Cargo.toml
- dependencies/gaptos/Cargo.toml

Docker image names must be lowercase. Hardcode the image path to avoid
case sensitivity issues with github.repository variable.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Changes:
- rust-ci.yml: Use pre-built Docker image (ghcr.io/galxe/gravity-sdk/rust-ci)
  - Merge all test jobs into single job to avoid redundant compilation
  - Use rust-cache for compilation caching
  - Only test packages that exist in workspace

- build-ci-image.yml: Use lowercase image name (Docker requirement)

- rust-ci.Dockerfile: Simplify to basic CI environment
  - Rust 1.88.0 + nightly rustfmt
  - System dependencies (clang, llvm, etc.)
  - Note: Actual image pushed manually from local build

- Delete migrated-tests.yml (merged into rust-ci.yml)

- Run daily at 00:00 UTC instead of on push
- Always build from main branch
- Add date-based tag (YYYYMMDD) for versioning
- Keep manual trigger option

- Use `docker run` instead of `container:` to enable host disk cleanup
- Pre-fetch cargo registry (~1.7GB) and git deps (~828MB) in Docker image
- Free ~20GB disk space before compilation (dotnet, android, ghc, etc.)
- Use CI profile for tests (reduced debug info, smaller artifacts)
- Clean incremental artifacts after build to save space

Docker image: ghcr.io/galxe/gravity-sdk/rust-ci:latest (5.56GB)

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Add --profile ci to clippy for faster builds
- Pre-compile all dependencies in Docker image (/opt/target-cache)
- Copy pre-compiled cache before cargo commands in CI
- Delete source files after compilation to reduce image size
- Use -j 2 to limit parallel jobs and reduce memory usage
- Use richard1048576 image registry for testing

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Disable GitHub Actions cache to ensure pre-compilation step runs
- Update Dockerfile to clone from Richard1048576/gravity-sdk for testing

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove Swatinem/rust-cache from Docker jobs (Docker image has deps)
- Add aggressive disk cleanup (~25GB) for build and clippy jobs
- This should fix "No space left on device" errors

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The git checkouts directory is needed at runtime when cargo resolves
git dependencies. Removing it caused "No space left on device" errors
when cargo tried to re-checkout dependencies.

Split serial test job into 4 parallel matrix groups (core, consensus,
gaptos, binaries) for both rust-ci and nightly-tests workflows. Switch
nightly tests from rust-cache to Docker image. Remove nightly schedule.

- Install sccache in Docker image with RUSTC_WRAPPER
- Add mozilla-actions/sccache-action to clippy, build, and test jobs
- Pass SCCACHE_GHA_ENABLED and Actions cache env vars to Docker

This enables cross-CI-run compilation caching via GitHub Actions Cache,
expected to reduce incremental build times from ~43m to ~10-20m.
RUSTC_WRAPPER in Dockerfile caused sccache to start before
GHA cache authentication was ready, failing with 400 error.

Now RUSTC_WRAPPER is set in each docker run command after
sccache-action has configured the cache credentials.
sccache cannot access GitHub Actions Cache API from inside Docker
container due to networking/auth issues. Reverting to simpler
approach using pre-compiled dependencies in Docker image.

Removed sccache-action and related env vars from all jobs.
- Add new build-tests job that compiles all tests once (~15m)
- Upload compiled artifacts using actions/upload-artifact
- Test jobs now download pre-built artifacts and skip compilation
- Expected to save ~60m total (6 jobs x 15m each -> 1 job x 15m)

This significantly reduces redundant compilation across test matrix.
Docker runs as root, creating files that runner user cannot read.
Added sudo chown to fix ownership before upload.
Also removed target/ci/build directory to reduce artifact size.
…compilation

- Keep target/ci/.fingerprint and target/ci/build directories
- Touch all files in target/ci to update timestamps before upload
- In test jobs, set source file timestamps to past date so Cargo
  sees compiled artifacts as newer than source, preventing rebuild

This should eliminate the redundant recompilation in test jobs.
…t runs

Major CI optimization:
- Install cargo-nextest in Docker image
- Build-tests job now uses 'cargo nextest archive' to create tar.zst
- Test jobs run 'cargo nextest run --archive-file' directly from archive
- No Cargo fingerprint checking or recompilation in test jobs

Expected improvement:
- Archive size: ~500MB vs 4.7GB target directory
- Download time: ~30s vs 4 minutes
- Run tests step: ~5min vs 40min (no recompilation)
- Total CI time: ~40min vs 78min
Add --cargo-build-jobs 4 to prevent runner memory exhaustion during test compilation.
Previous run failed with exit code 137 (OOM killed).
Also add CARGO_BUILD_JOBS=4 environment variable as backup.
Previous attempt with CARGO_BUILD_JOBS=4 still OOM'd (exit 137).
GitHub runners have ~7GB RAM which is insufficient for 4 parallel rustc processes.
Previous run failed with 'profile ci not found' error.
Added .config/nextest.toml with ci profile settings.
- core: use api, gravity-sdk, build-info (removed non-existent gravity-primitives, gravity-storage, api-types)
- consensus-core: safety-rules → aptos-safety-rules
- gaptos → executor: use aptos-executor, aptos-executor-types (gaptos package doesn't exist)
- Remove executor group: aptos-executor/aptos-executor-types have no tests
- Remove binaries group: gravity_node/gravity_cli have no tests
- Exclude test_dag_e2e from consensus-dag: panics with 'not yet implemented'
Translated from the internal Chinese doc and added to book/docs/ as
grafana.md. Covers:
- Docker Compose stack (Prometheus + Grafana + node-exporter)
- Prometheus scrape config for Gravity/Reth nodes
- Grafana provisioning for automatic data source and dashboard loading
- Reth dashboard import (manual and provisioning methods)
- Troubleshooting table and security/ops tips

Also updated book/docs/index.md to list the new page under Observability.
