closes#60
The fixture-corpus filter (NON_PARSEABLE_FIXTURES + list_ail_fixtures)
was copy-pasted across three test crates and drifted out of sync as
new reject fixtures landed; the examples_dir / workspace_root path
walk was reimplemented ~30 more times across the suite, under two
spellings (workspace_root / ws_root).
Introduce crates/ailang-test-support — a zero-dependency, dev-only
leaf crate — as the single home for these helpers:
- NON_PARSEABLE_FIXTURES, list_ail_fixtures
- workspace_root, examples_dir
- canonical_workspace_root (symlink-resolved variant, for the tsan/
race tests that feed the root into native build steps)
All integration-test copies across ailang-core, ailang-surface,
ailang-prose, ailang-check, and ail now import from the shared crate;
the local definitions and their now-orphaned path imports are removed.
Path helpers resolve via the support crate's own CARGO_MANIFEST_DIR,
so they return the correct absolute paths from any caller.
ail_bin helpers are intentionally left in place: they depend on
env!("CARGO_BIN_EXE_ail"), which Cargo only defines when compiling the
ail crate's own integration tests, so they cannot move to a shared
crate.
Behaviour-identical: same paths, same fixture lists; full workspace
test suite green. Net -177 LOC.
Restores the Decision-5 IR-readability affordance for main-free
kernels: ail emit-ir gains --emit=staticlib, symmetric with
ail build, reusing the M1-audited Target::StaticLib path via a new
one-line lower_workspace_staticlib convenience. Zero-export guard
byte-identical to build_staticlib's. DESIGN.md widened (not
narrowed) + a pre-existing M1 synopsis omission corrected. 3 new
E2E tests; no fixture minted, no doc pin (E2E is the coverage).
Plan 03493c9.
