Summary by CodeRabbit

  • New Features
    • Added Curio as an option for local devnet mining and sealing alongside Lotus Miner.
    • Added Curio miner integration tests, with separate commands for running the Lotus Miner and Curio test suites.
    • Improved devnet setup checks to wait for Forest RPC availability and chain validation before continuing.
  • Documentation

Walkthrough

The PR adds a Forest-produced Curio devnet and enables miner integration tests with either Curio or Lotus. It adds shared readiness helpers and updates CI, task definitions, and documentation for both backends.

Changes

Curio devnet and miner integration

Layer / File(s) Summary
Shared devnet configuration and readiness
scripts/devnet/upgrade_heights.env, scripts/devnet/chain_height.sh, scripts/devnet/{check,setup}.sh, scripts/devnet-forest-miner/{.env,check.sh,setup.sh}, scripts/devnet/test_harness.sh
Shared upgrade heights and RPC and chain-height wait helpers are added. Generic and Lotus Miner scripts use the helpers, and the test harness configures miner API access by backend.
Curio devnet build and startup
scripts/devnet-forest-curio/*
The new devnet builds or reuses a Curio image, starts Forest, Curio, and Yugabyte, and waits for Forest RPC and Curio initialization.
Backend-aware miner tests
src/dev/subcommands/devnet_cmd/miner*
Miner tests select Lotus or Curio. Curio helpers create miners, track sector status, and wait for Forest confirmation. Onboarding validation varies by backend.
CI, task, and user-facing integration
.github/workflows/lotus-api-bump.yml, .github/workflows/miner-tests.yml, mise.toml, docs/docs/users/guides/running_with_curio.md, docs/docs/users/reference/cli.md, scripts/devnet-forest-miner/README.md, scripts/devnet-forest-curio/README.md, .config/forest.dic
CI runs onboarding tests against both devnets. Tasks and documentation describe both backends. The Lotus API bump workflow also updates the Curio devnet environment file, and the dictionary adds Curio.

Estimated code review effort: 4 (Complex) | ~60 minutes

Possibly related PRs

  • ChainSafe/forest#7807: This PR extends the Lotus miner test implementation introduced by #7807 with backend selection and Curio support.
  • ChainSafe/forest#7820: Both PRs update the miner test matrix; group selection and Curio backend behavior need to align.
  • ChainSafe/forest#7802: Both PRs replace ChainHead polling in devnet scripts with different shared readiness mechanisms.

Merge Risk: Low · up to 908aa

The Curio guide may tell users to configure a value that the stack replaces automatically. Clarify the setup guidance; this bounded documentation risk does not otherwise block merging.

- Line 8: Replace the relative destination in the `scripts/devnet-forest-curio`
link with its absolute GitHub repository URL, keeping the link text and
surrounding sentence unchanged.

Review comments at @scripts/devnet-forest-curio/setup.sh:
- Around line 32-45: Bound the `.init.ready` wait loop with an elapsed-time
limit that allows a slow first boot to finish, and report the timeout and
container logs before exiting when the limit expires. Keep the existing
container-status check so failed containers still stop the wait early.

Forest’s admin token in token.jwt and configures FULLNODE_API_INFO with that
token and Forest’s RPC address; retain the instruction to keep the miner worker
