refactor(test): hoist duplicated test helpers into ailang-test-support
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. |

feat(lang): eliminate the Implicit ownership default — totality + the drop-soundness it demasks (#55)
Deletes `ParamMode::Implicit`. `ParamMode` is now `{Own, Borrow}`:
every fn-type slot on every signature carries an explicit `own` or
`borrow`, no defaulted position survives anywhere (model 0008 §2,
spec 0062). The parser rejects a bare fn-type slot; `borrow-return`
and `borrow-over-value` reject at the signature; the corpus is
migrated to minimal-ownership modes (consumed ⇒ own, read-only-heap
⇒ borrow, value ⇒ trivial-own). The documented `Implicit`-ret-mode
leak is fixed: an owned heap return now drops exactly once (live=0,
acceptance criterion 5).
This was the easy half. Removing the default ACTIVATED a family of
drop paths that `Implicit` had silently skipped — the pre-cutover
language was leaking (and in places mis-dropping) here rather than
crashing, because an Implicit scrutinee turned the drop off. Making
the modes explicit (Own) turned those paths on and exposed two
latent-bug clusters, all fixed RED-first as part of this cutover:
Drop-soundness family (four legs):
A. lit-sub-pattern double-free — the desugar re-matched the same
owned scrutinee in the lit fall-through; fixed by grouping
consecutive same-ctor arms into one match (bind fields once),
in ailang-core desugar.
B. Cons-husk leak on non-tail arm bodies — the lit-sub-pattern
desugar rebound the owned scrutinee via `Let $mp = xs`, which
bumped consume_count and suppressed the existing fn-return
partial_drop. Fixed by not rebinding a bare-Var scrutinee
(one husk-freeing mechanism, not two).
C. polymorphic `drop_<T>` rc_dec'd monomorphised value fields —
the per-ADT drop fn was emitted once from the polymorphic
TypeDef, defaulting type-var fields to ptr and rc_dec'ing
inline Ints (segfault). Fixed with per-monomorph drop
functions (new ailang-codegen::dropmono): the drop set is
collected from the lowered MIR, value-type fields are skipped,
heap fields still freed once; monomorphic-concrete ADTs keep
their byte-identical un-suffixed drop symbol.
D. static Str literal passed to an `(own Str)` param — the
literal lowers to a header-less rodata constant; the callee's
now-active rc_dec read its length field as a refcount and
freed a static address (segfault). Fixed with the missing
fourth StrRep::Static→Heap promotion in lower_to_mir's App arm,
gated on Own mode (borrow args stay static, no regression).
over-strict-mode lint over-fired: it suggested `(borrow V)` for
value-typed params (which `borrow-over-value` rejects — own is the
only legal mode there) and fired on `(intrinsic)` bodies (whose
consumption the linearity walk cannot observe). Tightened to skip
both; contract 0008 updated to the narrowed firing scope.
Irreversible step — canonical-form hash reset (model 0008 §6,
acceptance criterion 6). Every signature now carries explicit modes,
so the hashable canonical JSON changed for every module. RATIFY:
the corpus-wide hash-pin reset (hash_pin, prelude_module_hash_pin,
mono_hash_stability, eq_ord_e2e, embed_export_hash_stable, the
ct4/iter*/loop_recur schema-extension pins) and the list ir_snapshot
golden were regenerated once, deliberately, as the intended one-time
consequence of removing the mode elision from the canonical form —
not a regression. Each regenerated hash verified deterministic across
two runs.
Also fixes a pre-existing latent failure surfaced by the verification
gate, unrelated to this cutover: the `every_contract_names_a_resolvable_
ratifying_test` resolver (design_index_pin) could not resolve the
" + " dual-link ratifying-test form (`uniqueness.rs + linearity.rs`)
that the #57 audit-close (

iter form-a.1 (Tasks 6-12): milestone close
Second half of the form-a-default-authoring milestone-close iter
(Boss-decided strategy C, big-bang). All seven tasks DONE; cargo
test --workspace green at every per-task boundary.
T6 — Bench-driver suffix flip from .ail.json to .ail across 4
Python scripts + run.sh. compile_check.py + cross_lang.py exit 0.
T7 — Re-author e2e.rs raw-JSON-inspect tests:
- diff_detects_changed_def — derive sum.ail.json on-the-fly via
`ail parse examples/sum.ail` into tempdir, then mutate + diff.
- borrow_own_demo_modes_are_metadata_only — same pattern.
- reuse_as_demo_under_rc_uses_inplace_rewrite — same pattern.
- render_parse_round_trip_canonical — RETIRED (subsumed by T1's
cli_parse_then_render_then_parse_is_idempotent over whole corpus).
- ail_run_accepts_ail_source_with_same_stdout_as_ail_json —
re-authored to derive hello.ail.json in a per-process tempdir
from hello.ail via `ail parse`, then assert dual-form stdout.
T8 — Bulk-delete 156 non-carve-out .ail.json. Inventory:
8 .ail.json (carve-outs, alphabetical: broken_unbound + prelude
+ 3× test_22b2_* + 3× test_ct1_*) + 157 .ail. carve_out_inventory
test un-#[ignore]'d and green. Forward-pulled 20 repairs that the
T1-5 dispatch's recon missed (12 Group-B suffix + 5 Group-A
load_workspace + 3 ail_run sites). Also forward-pulled T9 Step 5
(schema_coverage corpus flip from .ail.json to .ail) to satisfy
T8's green-gate.
T9 — Retire obsolete roundtrip tests:
- print_then_parse_round_trips_every_fixture (round_trip.rs)
- every_ail_fixture_matches_its_json_counterpart (round_trip.rs)
- cli_render_then_parse_preserves_canonical_bytes_on_every_fixture
- Dead helpers: list_json_fixtures ×2, round_trip_one,
strip_trailing_newlines.
Schema-coverage corpus already flipped in T8 (forward-pull).
T10 — DESIGN.md §"Roundtrip Invariant" (lines 2027-2109) restated
with parse-determinism + idempotency + CLI-pipeline-idempotency +
carve-out-anchor framing. Five surviving enforcement tests named.
§"Float literals" and §"Why anchored at top level" preserved.
T11 — §A4 doctrine edits: CLAUDE.md:5-6 + DESIGN.md:465-466.
Canonical form remains JSON-AST; authoring projection is .ail;
build derives JSON-AST in-process via ailang_surface::parse.
T12 — Milestone close:
- WhatsNew entry: user-facing language, lead with the change.
- Roadmap: [milestone] form-a struck [x] with closing note.
- Final inventory verified: 8 .ail.json + 157 .ail.
- Final cargo test --workspace: 557 passed, 0 failed, 3 ignored.
- bench/compile_check.py + bench/cross_lang.py: exit 0.
Test math: pre-iter 558 baseline + 3 new T1 tests = 561, − 1
(T7 retire) − 3 (T9 retire) = 557 final.

iter form-a.1 (Tasks 1-5): additive phase + relocation
First half of the form-a-default-authoring milestone-close iter (Boss-decided strategy C, big-bang). All five tasks DONE; cargo test --workspace green at every per-task boundary. T1 — Add three new tests: - parse_is_deterministic_over_every_ail_fixture (round_trip.rs) - cli_parse_then_render_then_parse_is_idempotent (roundtrip_cli.rs) - carve_out_inventory.rs (new file; #[ignore]'d until T8 deletion) T2 — Bulk-render the 99 missing examples/<stem>.ail files via `ail render`. Corpus 58 .ail (pre-iter) -> 157 .ail. Eight .ail.json carve-outs (7 §C4(a) subject-matter + 1 §C4(b) prelude) preserved. One re-loop triggered: load_workspace prefers .ail siblings since ext-cli.1, so the newly-rendered imports broke seven Group-A entries whose JSON entry-paths now resolved imports to fresh .ail. Repair: pre-emptive forward-pull of five T3 migrations + 4 transient #[ignore]s on workspace.rs mod tests (cleanly relocated in T5). T3 — 14 Group-A test files migrated from ailang_core::load_workspace to ailang_surface::load_workspace + .ail paths. Carve-out lines preserved verbatim (7 sites in typeclass_22b2.rs / typeclass_22b3.rs). T4 — 12 Group-B test files: bulk regex flip on build_and_run / build_and_run_with_alloc / build_and_run_with_rc_stats call sites (~70 e2e.rs invocations + 11 subprocess sites). Four files mis-classified Group-A as Group-B in plan recon (mono_hash_stability, prelude_free_fns, print_mono_body_shape, show_mono_synthesis); two files mis-classified Group-B as Group-A (mono_recursive_fn, mono_xmod_qualified_ref). Migrated per actual shape, not plan label. T5 — Relocated #[cfg(test)] mod tests from production source to integration test crates with ailang-surface dev-dependency: - crates/ailang-core/tests/hash_pin.rs (10 tests from hash.rs) - crates/ailang-core/tests/workspace_pin.rs (10 non-carve-out tests from workspace.rs) - crates/ailang-codegen/tests/eq_primitives_pin.rs (3 tests from codegen/src/lib.rs:3717-3799) - ailang-prose/tests/snapshot.rs migrated (helper + 8 fixtures) to .ail + ailang_surface::load_module Carve-out tests in workspace.rs mod tests preserved in-place (3× 22b2 + 3× ct1 = 6 tests). Tempdir-based loader-mechanism tests (3 sites) also preserved — they don't consume examples/. Tests: 560 passed, 0 failed, 4 ignored (was 558 + 3 T1 new - 1 transit carve_out_inventory #[ignore] = 560 active). Tasks 6-12 (bench-driver suffix flips, e2e diff-test rewrite + 4 additional raw-JSON-inspect handlers, .ail.json deletion, retiring obsolete roundtrip tests + schema_coverage corpus flip, §C3 DESIGN.md restatement, §A4 doctrine edits, WhatsNew + roadmap strike) ship in the next dispatch on this iter ID. Known debt inherited to T6-12: 4 raw-JSON-inspect tests in e2e.rs (borrow_own_demo / reuse_as_demo / render_parse_round_trip_canonical / ail_run_accepts_ail_source_with_same_stdout_as_ail_json dual-form smoke) need rewrite or #[ignore] before T8 deletion; recorded in journal Concerns + Known debt sections. |

iter ext-rename: .ailx → .ail across the live toolchain
The surface-form file extension changes from .ailx to .ail. AILang's
authoring surface now uses the same .ail stem as its canonical JSON
form (.ail.json), giving the language a single coherent extension
family: .ail is the LLM-authored Form A, .ail.json is the canonical
JSON-AST Form B.
Scope (touched):
- 61 example renames examples/**/*.ailx → .ail (git mv)
- 1 rename experiments/.../rendered/ailx.md → ail.md
- 35 content-edited live-toolchain files (crates/, docs/DESIGN.md,
docs/roadmap.md, docs/PROSE_ROUNDTRIP.md, skills/, bench/reference/*.c,
experiment crates under experiments/.../{render,harness,master})
- Experiment-crate cohort rename Cohort::Ailx → Cohort::Ail,
Form::Ailx → Form::Ail, per_cohort/ailx → per_cohort/ail,
{form-only: ailx} → {form-only: ail}, ```ailx → ```ail
Out of scope (deliberately untouched, to preserve honest history):
- docs/journal-archive.md (content-frozen per CLAUDE.md)
- docs/journals/, docs/specs/, docs/plans/, bench/orchestrator-stats/
- experiments/.../runs/ (frozen LLM-output artefacts; models actually
saw .ailx — renaming would falsify the experimental record)
Verification: cargo build/test --workspace green; experiment crate
cargo test green; bench/check.py + compile_check.py + cross_lang.py
all 0-regressed; negative grep for ailx|Ailx|AILX outside the
out-of-scope paths returns zero matches.
Opens immediate follow-up: roadmap.md P2 todo `ail check`/build/run
accept .ail extension — after this rename, .ail is canonical
authoring surface but the CLI still produces a misleading JSON-parse
error on `ail check foo.ail`. That's the next iter.

iter rt.1: roundtrip-invariant audit tests — 3 new tests, all PASS first-shot
Three new reader-only tests pin the .ail.json / .ailx bijection plus AST-variant coverage. All three passed first observation across the current corpus — no roundtrip, schema-coverage, or CLI-drift gaps surfaced. - every_ailx_fixture_matches_its_json_counterpart (replaces the 3-pair handwritten exhibits): 57 paired .ailx fixtures pass. - every_ast_variant_is_observed_in_the_fixture_corpus (new): 34/34 AST variants exercised across 136 fixtures; exhaustive matches without _ wildcard so AST drift fails the build. - cli_render_then_parse_preserves_canonical_bytes_on_every_fixture (new): 136 fixtures round-trip through ail render → tempfile → ail parse with BLAKE3 identity on canonical bytes. No production code, no DESIGN.md changes (those follow in later iterations). Tests are pure readers of the repo per spec acceptance #7 — tempfile crate added as workspace dep for the CLI roundtrip's intermediate file outside the repo. |
