Pull request overview

Updates workflow/action pin fixtures and related tests to align with recently updated GitHub Action pins used by the workflow compiler/runtime setup generation.

Changes:

• Updated expected pinned SHAs in runtime_setup_test.go for bun/node/go/haskell setup steps.
• Added new action pin entries in action_pins.json (e.g., github/stale-repos, super-linter).
• Adjusted action_pins_test.go expectations for pin selection and pin counts.

• The semver-preference test names mention preferring v6.2.0 over v6, but action_pins.json currently has no version: "v6" entries for actions/setup-go or actions/setup-node (only v6.2.0). Either add the corresponding v6 pins to make this a real preference test, or rename the cases to avoid implying coverage that isn’t present.

TestGetActionPinsSorting asserts len(pins) == 38, but getActionPins() returns one element per JSON entry in data/action_pins.json, which currently contains 23 entries. This will make the test fail; update the expected count to match the JSON (or compute it from the embedded data instead of hardcoding a number).

Suggested change

	// Verify we got all the pins (38 as of February 2026)
	if len(pins) != 38 {
	t.Errorf("getActionPins() returned %d pins, expected 38", len(pins))
	// Verify we got all the pins (23 as of February 2026)
	if len(pins) != 23 {
	t.Errorf("getActionPins() returned %d pins, expected 23", len(pins))

In TestGetActionPinWithData_SemverPreference, the second setup-go case duplicates the first (both request v6.2.0 and expect v6.2.0), so it no longer exercises the fallback behavior for major tags (e.g. requesting v6 when only v6.2.0 exists). Consider changing this case to request v6, expect the comment to remain # v6, and set shouldFallback accordingly so the semver-compatible fallback path stays covered.

This issue also appears on line 545 of the same file.

See below for a potential fix:

			name:           "fallback to highest semver-compatible version for setup-go when requesting v6 from hardcoded pins",
			repo:           "actions/setup-go",
			requestedVer:   "v6",
			expectedVer:    "v6", // Comment shows requested major version, not the pin's v6.2.0
			strictMode:     false,
			shouldFallback: true,
