B=$B
C=$Z

$ varlock load
main:
  💥 [varlock] varlock stopped before the command finished 💥

here:
  B   - Item cannot have dependency on itself
  C   - ref(): invalid dependency: Z

each line alone gives its proper error on main. together they give neither.

cause:

finishLoad():
  process every item
  if (any item has an error) return      // C=$Z has one
  mark items that are on a cycle         // never reached, so B is unmarked

resolveEnvValues():
  B waits for B                          // forever

fix: mark cycles before that early return.

context: found by a fuzzer that compares varlock against a small reference implementation of the schema language, part of the same exploration as #469.

test: cycle-with-schema-error.test.ts. on main it never finishes.

✅ No new issues found.

Reviewed changes: Reviewed cycle detection ordering, error propagation, and the regression test; all 129 focused tests passed.

• Cycle diagnostics: Marks dependency cycles before returning for other schema errors, preventing resolution from waiting indefinitely.
• Regression coverage and release note: Tests a self-reference alongside a missing reference and records the fix for a patch release.
