Walkthrough

The external RPC workflow now supports labeled pull-request runs, conditional Forest builds, ARM runners, configurable Forest images, and native ARM RPC checks.

Changes

External RPC checks

Layer / File(s) Summary
Workflow triggers and ARM build
.github/workflows/external-rpc-checks.yml
The workflow cancels superseded runs, responds to eligible pull-request labels, builds Forest when required, transfers artifacts, uses ARM runners, and builds the test image for linux/arm64.
RPC image selection and native ARM checks
.github/workflows/external-rpc-checks.yml, scripts/tests/external-rpc-checks/.env, scripts/tests/external-rpc-checks/docker-compose.yaml
The workflow configures FOREST_IMAGE. Docker Compose uses the configured image and removes amd64 platform overrides from the verification services.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 6b4a9

This workflow change adds manual and label-triggered RPC checks, but manual runs cannot select the required published Forest image, the built image omits required proof parameters, and unlabeled pull requests skip the check without the expected no-op behavior. The PR is not merge-ready until these workflow behaviors are corrected or explicitly accepted.

Disable persisted checkout credentials for PR code.

Both workspaces later execute PR-controlled code through mise run install and ./setup.sh. actions/checkout persists its token in local Git configuration by default. Set persist-credentials: false unless a later step requires authenticated Git access.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Add a dispatch input for the published Forest image.

workflow_dispatch has no input for FOREST_IMAGE. Line 24 therefore always builds the selected ref. A manual run cannot select a specific published image without changing the checked-out .env file.

Add an optional image input. Skip build when that input is set. Export the selected value to FOREST_IMAGE in rpc-checks.

Keep the required fat-image contents in the built-image path.

This step overrides FOREST_IMAGE with forest-under-test:ci. scripts/devnet/forest_ci.dockerfile creates that image from Ubuntu and copied binaries only. It does not include the pre-downloaded Filecoin proof parameters required by scripts/tests/external-rpc-checks/.env.

Build the test image from a fat base, or provision the required proof parameters before ./setup.sh runs. Otherwise labeled and dispatch runs can fail or download the parameters during the check.

Add the required no-op path for unlabelled pull requests.

rpc-checks is skipped when a pull request has neither RPC nor Release. This workflow has no separate no-op job. Add the required successful no-op job, or keep the required check job running and disable only its check steps.

I don't quite get the dance around the platforms; this should be invisible. If there are some limitations, let's just publish a multi-arch image of the checker, it should be trivial and cheap to do (it's just a ruby script).
