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.
Tasks 1-5 GREEN. T1 baseline pins (re-point annotation + @ailang_rc_alloc
heap-box byte-pin: size=8+n*8, tag@0, fields@8/16). T2 export gate widened
(is_c_scalar -> two-level is_c_abi_type: single-ctor all-Int/Float record;
multi-ctor/Str/List/nested still RED; gate suite 10/10; M1 adt-ret must-fail
re-pointed to multi-ctor+Str Reading). T3 codegen forwarder widened
(llvm_scalar record Type::Con -> ptr; M2 forwarder body byte-unchanged;
3/3 staticlib pins). T4/T5 E2E record round-trip own+borrow, global
leak-freedom.
Boss spec-consistency repair (M2.1-precedent class): orchestrator
correctly BLOCKED Task 5 on a genuine spec defect -- the single-ctx-readback
allocs==frees proof model is unsatisfiable for borrow (and only
coincidentally passes for own) because M2's TLS-ctx is bound only during
the synchronous forwarder call, so host-side decs land on g_rc_*, not ctx.
Boss-verified globally leak-free + value-correct both modes. Spec + plan +
harness amended to the stronger global model (sum all ailang_rc_stats:
lines; the M2-TLS cross-attribution documented as correct behaviour). No
fresh grounding-check (removes an over-strong measurement assumption).
Tasks 6 (DESIGN.md frozen-layout SSOT + lockstep pointers + freeze wording
+ enforceability demo) and 7 (workspace-green gate) re-dispatched on the
amended plan. Bench/architect milestone-close is audit-owned.
