Add Signer CI

Add Fork Signer to CI

Prepare CI workflows for a new signer being added via a fork PR. This is a two-phase process because fork PRs can't use repository secrets, so fork-external-live-manual.yml (which runs from main's YAML) must be updated on main first.

If any of these are unknown, ask the user for: signer display name, Rust feature name, Rust integration test function name, TypeScript package name (if any), and required environment variable names.

Phase 1 — Our Preparatory PR (merged to main)

This is what YOU do. Read each file first, then make edits matching existing patterns exactly.

1. .github/workflows/fork-external-live-manual.yml

a) Rust test step env vars (Run Rust external live integration tests → env block): Add the signer's env vars after the last existing signer's env vars, before SOLANA_RPC_URL.

b) Rust test step tests array (same step → tests=() bash array): Add the Rust integration test function name to the array.

c) TypeScript test step env vars (Run TypeScript external live integration tests → env block): Add the signer's env vars (if the signer has a TypeScript package).

d) TypeScript test step packages array (same step → packages=() bash array): Add the TypeScript package name (if applicable).

2. .github/workflows/ci.yml — env vars ONLY

Integration test env vars (rust-integration-test job → env block): Add the signer's env vars after the last existing signer's env vars, before SOLANA_RPC_URL.

DO NOT add to the backend matrix or test matrix. The Rust feature and test don't exist on main yet — adding them would break CI. Those go in Phase 2.

Phase 2 — Fork Contributor Adds to Their PR

Tell the fork contributor (in a PR comment or issue) to add these to their branch alongside the signer code:

1. .github/workflows/ci.yml

a) Unit test backend matrix (rust-test job → strategy.matrix.backend): Add the Rust feature name to the backend array, before all.

b) Integration test matrix (rust-integration-test job → strategy.matrix.test): Add the integration test function name to the test array.

2. .github/workflows/typescript-ci.yml (if TS package exists)

a) Unit test matrix (typescript-test-unit job → strategy.matrix.package): Add the TypeScript package name.

b) Integration test matrix (typescript-test-integration job → strategy.matrix.package): Add the TypeScript package name.

c) Integration test env vars (integration test step → env block): Add a comment header and the signer's env vars.

3. .github/workflows/typescript-publish.yml (if TS package exists)

a) PUBLISH_PACKAGES env list: Add the package name in dependency order (before keychain umbrella).

b) GitHub Release packages array (in the actions/github-script step): Add @solana/keychain-<name> to the array.

c) Publish summary table: Add a row for the new package.

Merge Order

1. Merge Phase 1 PR → main is ready with secrets wired up
2. Trigger Fork External Live Tests workflow with the fork PR number → integration tests run with secrets
3. Merge the fork PR (Phase 2 changes included alongside the code)

GitHub Secrets Reminder

After updating CI files, the following secrets must be configured:

• Repository level (Settings → Secrets → Actions): for ci.yml workflows
• external-live-tests environment (Settings → Environments → external-live-tests → Secrets): for fork-external-live-manual.yml

Both locations need the same secret names configured.

Verification

After making Phase 1 changes:

1. Confirm fork-external-live-manual.yml has the new env vars and test entries (Rust and TS if applicable)
2. Confirm ci.yml has the new env vars but NOT the matrix additions
3. Confirm CI passes (no references to nonexistent features)
