ANS Forth conformance tests — vendored from
https://github.com/gerryjackson/forth2012-test-suite (master, commit-locked
on first fetch: 2026-04-24).

Files in this directory are pristine copies of upstream — do not edit them.
They are consumed by the conformance runner in `lib/forth/conformance.sh`.

- `tester.fr` — John Hayes' test harness (`T{ ... -> ... }T`). (C) 1995
  Johns Hopkins APL, distributable under its notice.
- `core.fr` — Core word set tests (Hayes, ~1000 lines).
- `coreexttest.fth` — Core Extension tests (Gerry Jackson).

Only `core.fr` is expected to run green end-to-end for Phase 3; the others
stay parked until later phases.
