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`)

iter intrinsic-bodies.2-migration-lock (DONE 4/4): prelude → (intrinsic) + bijection pin (refs #9)
Second and final iteration of the intrinsic-bodies milestone. Migrates
the 13 authored prelude dummy bodies to (intrinsic), rebaselines the two
hash pins that move, and locks the registry to the source with a
bijection. Behaviour-preserving: the codegen intercepts emit identical
IR; the prelude placeholder bodies were already dead (intercepted by
name before lower_term, since raw-buf.1).
What landed (4 tasks):
Task 1 — examples/prelude.ail: 13 authored dummy bodies → (intrinsic).
7 Eq/Ord instance methods (eq Int/Bool/Str/Unit, compare
Int/Bool/Str) keep their lambda shell (params/ret = the method's
local signature, Design X); the inner (body false)/(body true)/
(body (term-ctor Ordering EQ)) becomes (intrinsic). 6 float_* fns
((body false) → (intrinsic) in the fn body slot). The honesty-rule
infraction the milestone exists to fix is now closed: no prelude
body lies about what runs.
Task 2 — hash rebaselines (the prelude bytes changed):
prelude module hash af372f28c726f29f → 2ea61ef21ebc1913
eq__Int 86ed4988438924d3 → cc7b99b63d1e44ae
eq__Bool d62d4d8c51f433f8 → fd0412f127986512
eq__Str 3d32f377c66b03e0 → fa269285754a52da
compare__Int 6d6c20520766368b → 0a02bd9effc9746c
compare__Bool 02b64e8fadc913eb → d0dc108dacf4e543
compare__Str 9645929d53cd3cc9 → d1419595dc52a456
The 4 show__* mono pins did NOT move (Show bodies are real).
Task 3 — intercepts.rs: registry_contains_all_legacy_arms (one-
directional, hardcoded 18-name list) replaced by
intercepts_bijection_with_intrinsic_markers. The in-source test
walks prelude + kernel_stub pre-mono for Term::Intrinsic markers,
recovers each marker's codegen symbol (mono_symbol(method, type) for
instance methods; the fn name for top-level float_*/answer), and
asserts a bijection over the intrinsic-backed class: (A) every
marker resolves to an INTERCEPTS entry, (B) every INTERCEPTS entry
not on the optimisation-only allowlist has a marker, plus a guard
that the allowlist names are themselves registered. The allowlist is
the 5 *__Int icmp-family entries, which intercept the monomorphised
specialisation of the real-bodied polymorphic lt/le/gt/ge/ne — an
optimisation, not a compiler-supplied body, so no marker. The pin
passing independently confirms Task 1 missed no prelude site.
Task 4 — confirmed no codegen path lowers an intercepted body (already
true since raw-buf.1: try_emit_primitive_instance_body matches by
name before f.body is inspected). Refreshed the now-accurate comment
at lib.rs:1310-1319. design/contracts/0007-honesty-rule.md needed NO
edit — it is a general present-tense rule and does not name the
prelude dummies (confirmed by grep), so editing it would have been
invented work.
Verification:
cargo test --workspace → 669 passed, 0 failed (post-.1 baseline held;
one test replaced net-0).
Behaviour-preservation ratifiers GREEN (the safety net):
eq_primitives_smoke_compiles_and_runs,
compare_primitives_smoke_prints_1_2_3_thrice (e2e.rs);
float_compare_smoke_prints_true_true_false (float_compare_smoke_e2e.rs);
eq_ord_polymorphic_runs_end_to_end (eq_ord_e2e.rs).
Bijection pin GREEN. Both hash pins GREEN at the new baselines.
bench/check.py + compile_check.py → 0 regressed.
Plan-text imprecision (no outcome impact, noted for the record): Task 1
Step 5 wrote `--test e2e` for all four ratifiers, but
float_compare_smoke_prints_true_true_false and
eq_ord_polymorphic_runs_end_to_end live in their own test targets
(float_compare_smoke_e2e.rs, eq_ord_e2e.rs). The verification-filter
self-review checked that the fn names exist, not that they sit in the
named target — a sharper form of the filter-zero discipline. The
implementer ran each in its real target; all four green.
Milestone intrinsic-bodies is now feature-complete (.1 mechanism +
.2 migration+lock). Audit + close follow.

iter prep.3-kernel-tier-modules (DONE 9/9): kernel-tier modules + param-in + stub crate — closes #33
Terminal iteration of the kernel-extension-mechanics milestone. Ships
the four language-level mechanisms named in the spec's § Goal:
Module.kernel + TypeDef.param-in schema, their Form-A surface,
flag-driven kernel-tier auto-injection, and generic param-in checker
enforcement with a new diagnostic.
Schema (Tasks 1+2). Module gains a `kernel: bool` field
(skip_serializing_if = is_false), TypeDef gains a
`param_in: BTreeMap<String, BTreeSet<String>>` field
(skip-if-empty, kebab-renamed to "param-in"). Both fields are
strictly additive — every pre-existing fixture's canonical-JSON hash
is bit-stable except `prelude.ail`, which intentionally gains
`(kernel)`. The struct-literal sweep covered ~104 Module sites and
~35 TypeDef sites across the workspace; the additive serde-default
covers JSON deserialise paths, only Rust struct literals broke.
Form-A surface (Tasks 3+4). `(kernel)` is a bare module-header
attribute; `(param-in (a Int Float) (b Str))` is one outer
TypeDef-body clause carrying one or more inner var-lists (OQ1
decision — mirrors `(ctors …)`, one parser arm, deterministic
BTreeMap iteration). Both round-trip Form-A → JSON → Form-A
bit-identical.
Workspace-load migration (Task 5). The hardcoded `&["prelude"]`
literal at loader.rs:108 became a `modules.values().filter(|m|
m.kernel)` derivation; `parse_prelude()` injection stays because
the prelude has no on-disk manifest in user workspaces. Prelude
now carries `(kernel)` in its source, so the new filter picks it
up automatically. Code-path migration only — observable behaviour
is identical (prelude_free_fns.rs stays green). prelude hash
re-pinned (af372f28c726f29f) with Honesty-Rule provenance comment.
WorkspaceLoadError::ReservedModuleName diagnostic prose
repurposed: any built-in kernel module name is reserved
(currently prelude + kernel_stub), not specifically prelude. CLI
mapping at main.rs updated in lockstep.
Stub crate (Task 6). New `crates/ailang-kernel-stub/` is a
zero-dependency leaf crate carrying only `pub const STUB_AIL:
&str` with the Form-A source of the kernel_stub module (one
parametric TypeDef with param-in, one ctor). The parse hop —
`parse_kernel_stub()` — lives in ailang-surface next to
parse_prelude, keeping the crate-dependency graph acyclic
(`ailang-surface → ailang-kernel-stub → ailang-core`, no
back-edge). The stub is injected unconditionally in all builds as
the ratifying fixture for the kernel-extension mechanism; future
base extensions may add more or retire the stub. Drift-pinned by
`kernel_stub_module_round_trips`.
Checker (Task 7). New `CheckError::ParamNotInRestrictedSet`
variant + code() + ctx() arms + enforcement in
`check_type_well_formed`'s Type::Con arm — generic, data-driven
from the TypeDef, mentions no specific extension type. Two
in-source tests pin both the rejection (`Str` outside `{Int,
Float}`) and the acceptance (`Int` inside) paths.
Workspace-load integration tests (Task 8). New
`workspace_kernel.rs` integration-test crate with three tests:
auto-import without explicit `(import …)` declaration, two
kernel-tier modules co-load, explicit-import-overrides-auto-
import precedence preserved. Loader is import-tree-only so the
auto-import tests use a bridge module that brings the kernel
module into the workspace via the import graph — docstring
captures the reachability nuance for future readers.
Doc-state transitions (Task 9). INDEX.md kernel-extensions row
annotation transitions from "design accepted 2026-05-28; impl in
progress" to "mechanisms milestone closed 2026-05-28; raw-buf and
series milestones pending". Whitepaper STATUS + auto-import +
param-in sections transitioned forward→present for shipped
mechanisms; forward-tense survives only in sections describing
the still-pending raw-buf/series milestones (per Honesty-Rule).
data-model contract gains anchor blocks for both new schema
fields.
Side-effect: every binary's IR snapshot now contains ~52 lines
for `drop_kernel_stub_StubT` because the stub is auto-injected
into every workspace load. Snapshots refreshed; e2e expects 4
modules per workspace (prelude + kernel_stub + entry + zero or
more user modules) instead of the previous 3.
Plan defects scrubbed in the implementation (folded back into
the planner template via the planner's self-review checklist
next time): Task 4 sample test src used fictional
`(ctors (MkT a))` list form (project grammar is per-`(ctor MkT
a)`); Task 6 original wiring would have created a cycle
ailang-surface → ailang-kernel-stub → ailang-surface (inverted —
stub crate is zero-dep, parse hop lives in surface); Task 7 in-
source tests referenced a fictional `check_type_in_module`
helper (used the existing Workspace + check_workspace
convention); Task 8 first integration test expected loader to
auto-load kernel modules from disk (loader is import-tree-only;
tests use a bridge module).
Concern-5 fix folded in pre-commit: workspace.rs ReservedModuleName
doc-prose initially said "in test/dev builds" for kernel_stub —
but stub is unconditionally injected in all builds. Doc copy
tightened to present-state per Honesty-Rule.
Stats: 0 spec-review-loops, 0 quality-review-loops, 2 sweep-script
retries on Task 2 (brace-depth bug on nested vec![Ctor{…}],
recovered via per-file checkout + rewritten anchor-on-existing-
field sweep), 1 e2e-snapshot refresh on Task 6.

iter operator-routing-eq-ord.1 (DONE 13/13): drop comparator builtins, route through Eq/Ord
Closes Gitea #1. Realises the "P2 follow-up" called out in examples/prelude.ail:9 — removes the surface comparator names `==` / `!=` / `<` / `<=` / `>` / `>=` from the language entirely, routes the LLM-author's `(app eq …)` / `(app compare …)` / `(app ne|lt|le|gt|ge …)` through prelude.Eq / prelude.Ord class- dispatch, ships six named Float-comparison fns (`float_eq`/`float_ne`/`float_lt`/`float_le`/`float_gt`/`float_ge`) so Float keeps comparability without an Eq/Ord instance, and emits primitive instance bodies with `alwaysinline` so the -O0 IR shape stays at one instruction per comparison. Plan-task journal (13 tasks, single atomic iter per Approach A): Task 1 — Bootstrap: 4 new fixtures (eq_user_adt_smoke.ail, eq_float_must_fail.ail, float_compare_smoke.ail, operator_unbound_check.ail) + 5 new E2E/pin tests as RED starting state. All 5 confirmed RED at start: north-star fixed `NoInstance Eq Unit` (preserved by Unit-eq opening line intentionally added in plan-self-review); float_compare unknown `float_eq`; operator-name typechecked (== still polymorphic); must-fail diagnostic lacked `float_eq`; alwaysinline absent from IR. Task 2 — Codegen alwaysinline + intercept arms: introduced `intercept_emit_wants_alwaysinline` allowlist + appended ` alwaysinline` between `)` and `{` of the `define` line in `emit_fn`; added 9 new intercept arms to `try_emit_primitive_instance_body` — `eq__Int`/`eq__Bool`/ `eq__Unit` + the six `float_*` arms. Task 3 — Prelude reshape: `instance Eq Unit` added; Eq Int/Bool bodies become placeholder-`false` (intercept overrides); six `float_*` free fns added; line-9 P2-follow-up comment removed. Lockstep hash re-pins: prelude_module_hash_pin (3abe0d3fa3c11c99 → new), mono_hash_stability six body-hash literals (eq__Int/Bool/Str + compare__Int/Bool/Str all shifted because placeholder body changes the canonical hash). IR-snapshot regen (hello/list/max3/sum/ws_main) rolled forward into this task at orchestrator's pragmatic call — prelude shift forces the snapshots immediately. Task 4 — Fixture migration: 58 .ail fixtures rewritten (`(app == …)` → `(app eq …)`, etc.; Float-typed operand sites to `(app float_eq …)` / `(app float_lt …)`). eq_ord_user_adt.ail:21 inner `==` → `eq` migration with lockstep eq_ord_e2e.rs:134 body-hash re-pin (3c4cf040cb4e8bb2 → new). Two prose snapshots accepted; deps test + 5 hash_pin literals updated as cascading consequences. Task 5 — Test-scaffold migration: all 8 in-source `#[cfg(test)] mod tests` AST-literal sites threaded (desugar.rs:2414, check/lib.rs:5656/6092/6220, codegen/lib.rs sites). 7 obsolete in-source tests deleted (5 eq_typechecks + 2 lower_eq ADT/Fn rejection — coverage moves to E2E eq_user_adt_smoke + eq_float_must_fail). 2 additional letrec tests deleted (single-module check env can't resolve eq/ge without prelude auto-import; covered by workspace E2E). Task 6 — Lit-pattern desugar: build_eq emits `Term::Var { name: "eq" }` instead of `"=="` at desugar.rs:1109; doc-comment rewritten to describe class-dispatch. Task 7 — Dead-machinery deletion sweep (compile-gated): typchecker builtins (install + list comparator entries deleted); codegen builtin_binop_typed (10 comparator arms deleted from synth.rs, table reduced to arithmetic core); lower_eq fn entirely deleted; `==` short-circuit in lower_app deleted; `is_static_callee` `==` clause deleted; `is_arithmetic_or_comparison_op` renamed to `is_arithmetic_op` + caller-update at codegen/lib.rs:2152 + :2529. Dead `poly_a_a_to_bool` helpers also removed. Workspace build green after compile gate — every caller of the deleted surface was migrated by Tasks 4-6. Task 8 — Float-aware NoInstance diagnostic: check/lib.rs:856-880 addendum extended to name `float_eq` / `float_lt` as the explicit alternative for Eq/Ord at Float; eq_float_noinstance.rs:32-44 assertion extended. Task 9 — IR snapshot regen: subsumed by Task 3 (prelude shift forced immediate snapshot regen; deferring to Task 9 would have left the workspace red between tasks). Task 10 — Prose-projection cleanup: 6 comparator arms deleted from binop_info; 3 in-source mod-tests updated/deleted (comparator-infix rendering would be dishonest now that the operators are no longer language identifiers). Task 11 — Contract updates: 5 design files rewritten to the class-dispatch present — float-semantics.md (arithmetic guarantees retained on +/-/*/; comparison guarantees transferred from ==/!=/< to float_eq/float_ne/float_lt/etc.); prelude-classes.md (Eq Unit added to instance list; new paragraph on six float_* fns; Float-no-Eq/Ord clause gains `→ use float_eq` cross-reference); str-abi.md (clause "REMAIN primitive operators" rewritten to describe class-method dispatch); scope-boundaries.md (multiple operator-name and Pattern::Lit-desugar clauses rewritten); authoring-surface.md (==, <= dropped from operator-example list). Task 12 — Initial acceptance gate: workspace 638/0 GREEN; bench/compile_check + cross_lang 0 regressed; bench/check.py flagged 4 regressions on bench_closure_chain (+29% bump_s, +47% rc_s, +29% bump_rss_kb, +48% rc_rss_kb). Orchestrator initially classified as DONE-with-concerns; Boss reclassified as PARTIAL-via-acceptance-#8-fail after independent re-run, extended iter scope to Task 13. Task 13 — Direct icmp intercept arms (Boss-extension): try_emit_primitive_instance_body gains direct-icmp arms for lt__Int / le__Int / gt__Int / ge__Int / ne__Int, bypassing the compare__Int → Ordering → match indirection that allocated one Ordering ctor per call in tight loops. Each new arm inherits `alwaysinline` via the existing allowlist (extended accordingly). New IR pin test `ord_int_intercept_ir_pin.rs` + smoke fixture `ord_int_intercept_smoke.ail` ratify the optimization — opt -O2 -S confirms zero `call @ail_prelude_lt__Int` in optimized IR; the icmp folds directly at every use site. Bool variants (lt__Bool/etc.) deliberately NOT added — no bench/example calls Ord at Bool; spec-extension permits skipping if unreachable at bench level. Family can be extended symmetrically when first Bool-ordered perf workload appears. Bench-gate post-Task-13: bench_closure_chain bump_s -6.05%, rc_s -2.67%, bump_rss_kb -0.77%, rc_rss_kb +0.46% — all four previously-regressed metrics back inside tolerance. Full bench corpus: 36 metrics, 0 regressed, 0 improved beyond tolerance, 36 stable. bench/check.py exit 0 ✓; bench/compile_check.py exit 0 ✓; bench/cross_lang.py exit 0 ✓. Workspace: 640 passed, 0 failed across all binaries (delta vs. milestone start: +5 new E2E/pin tests added in Task 1 + 1 IR pin added in Task 13 − 9 in-source mod tests deleted as obsolete net ≈ −3). The eq_user_adt_smoke fixture's Unit-opening line was the deliberate RED-first device added in planner self-review so the north-star wouldn't accidentally GREEN at start (user-ADT-Eq on Point with hand-written instance was already operable today; the milestone's actual delivery is operator-name death + Eq Unit + Float-named-fns + cleanup of the two-pathy primitive comparator machinery). Net delta: 96 files changed, 1760 insertions, 1101 deletions; 12 net-new files (6 new fixtures, 5 new E2E/pin tests, 1 stats file). main passes-test-count: 640 (was 633 pre-iter, accounting for the deletions). Spec-vs-acceptance addendum: spec §Testing strategy anticipated the bench-gate-regression case with two recovery paths (`alwaysinline` investigation or "spec needs revisiting toward α"). Task 13 is the third path — direct intercept arms for `lt`/etc. that bypass the compare→match path entirely. The spec's contingency clause was thus generous enough to absorb Task 13 without spec revision, but a future iter that hits a class-method primitive where the body shape introduces a similar codegen cost (Ordering allocation, RC tax, deferred-init) should expect a parallel extension. The pattern is "primitive instance whose canonical body indirects through other class methods that allocate" → add a direct-emit intercept arm + alwaysinline + IR-shape pin. Concerns absorbed: - Codegen lower_app / resolve_top_level_fn gained a prelude-fallback lookup so bare monomorphic prelude fns (`float_eq` etc.) resolve from non-prelude modules without explicit `prelude.float_eq` qualifier. Mirrors the typechecker's implicit prelude import — not in plan but necessary infra for the named-fn surface to be callable. - Recon's "≈10 fixtures" estimate was 6× too low — 58 actual. Mechanical migration; no design impact. - Recon caught 4 in-source AST-literal sites the spec missed (lib.rs:5656 `>=` site + three codegen/lib.rs sites); Task 5 covered all. - Recon caught 2 contract files outside the spec's update set that directly contradicted the milestone (str-abi.md + scope-boundaries.md "REMAIN primitive operators" / "Pattern::Lit desugar to ==" clauses); Task 11 covered all 5.

bugfix: print leak — propagate ret_mode through rigid substitution
`(app print x)` under --alloc=rc leaked the heap-Str allocated by
`show x` in print's body: the let-binder `s` in
`(let s (app show x) (do io/print_str s))` was never flagged
trackable, so the drop site at scope-close emitted no
`ailang_rc_dec(s)`. Minimal repro `(body (app print 42))` produced
`allocs=1 frees=0 live=1`.
Root cause is two-layer:
1. examples/prelude.ail.json declared the Show class method `show`
without an explicit `ret_mode` on the return type, so serde
defaulted to ParamMode::Implicit. Fix: add `"ret_mode": "own"`
on the Show.show method, parallel to how the heap-Str-producing
builtins (int_to_str, bool_to_str, float_to_str, str_clone,
str_concat) declare it. examples/prelude.ail regenerated via
`ail render` to stay parse-isomorphic with the JSON.
2. crates/ailang-check/src/lib.rs `substitute_rigids` was silently
stripping `param_modes` and `ret_mode` whenever it rebuilt a
`Type::Fn`, so even after the prelude fix, the mono-synthesised
`show__Int / Bool / Str / Float` lost the `Own` annotation
during rigid substitution. Fix: preserve both fields through
the substitution.
RED pin: crates/ail/tests/print_no_leak_pin.rs (test
`alloc_rc_print_int_does_not_leak_show_result_str`) + fixture
examples/print_int_no_leak_pin.ail asserts allocs == frees and
live == 0 for `(body (app print 42))` under --alloc=rc.
Ten mono-body hash pins re-recorded (eq__Int/Bool/Str,
compare__Int/Bool/Str, show__Int/Bool/Str/Float, eq__IntBox) —
the bodies are semantically identical; the canonical JSON now
carries the previously-stripped mode metadata, so the body hash
moves. Re-pinning is bookkeeping for the intentional drift, not
a workaround.
Surfaced 2026-05-14 during the rpe.1 BLOCKED orchestrator run
(Cat A). Existed in latent form since iter 24.3 (when Show + print
shipped); only became user-observable when `(app print ...)` joined
the corpus. cargo test --workspace: 565 / 0 / 3.
Open follow-up flagged for next /audit: grep for `Type::Fn { ..., .. }`
field-spread sites — any other shape that drops modes during
rebuild is a latent instance of the same bug class. Out of scope
for this minimal fix.

iter form-a.0: prelude pilot — examples/prelude.ail rendered
First iteration of the form-a-default-authoring milestone. Mechanical: one `ail render examples/prelude.ail.json > examples/prelude.ail` captures the canonical Form-A projection (116 lines / 6386 bytes). No source-code edits, no test edits. The two auto-discovering roundtrip tests in crates/ailang-surface/tests/round_trip.rs pick up the new fixture via read_dir without test changes and both pass: - every_ail_fixture_matches_its_json_counterpart — the .ail parses to canonical bytes byte-equal to prelude.ail.json (gate test). - parse_then_print_then_parse_is_idempotent_on_every_ail_fixture — the Form-A printer is idempotent over prelude. cargo test --workspace green at 558 tests (identical to pre-iter baseline; audit-24 / iter-24.tidy lineage). prelude.ail.json retained per spec §A2 — this is the singular dual-form iter; iter 1 deletes it alongside the bulk test-infra refactor. Zero re-loops, zero review-phase repairs. Recon predictions matched reality exactly (116 lines, 6386 bytes, `(module prelude` header, 558-test baseline). Strong signal that the iter-1+ bulk migration mechanism is sound. |
