Brummel 7ae92d3e60 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.

Brummel 76b21c00eb 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 (dfdc65f) introduced — it shipped red on that
commit. Resolver taught the dual-link form, mirroring its sibling.

Verification: cargo test --workspace = 731 passed, 0 failed (twice,
stable); e2e 102 passed, no binary exits non-zero (corpus crash-free);
grep-clean for Implicit/fn_implicit/mode_eq across crates; every drop
fix confirmed via emitted IR + AILANG_RC_STATS balance on the head==K,
head!=K, and Nil paths. Three BLOCKEDs en route (the unsound first
husk-dec attempt, the over-strict derivation premise, the leg-B fix
direction) were each treated as a real design/spec gap and rediagnosed,
not patched over.

Supersedes #54 (return-position-only leak patch). Precondition #57
(linearity hardening) was already met. Spec docs/specs/0062, plan
docs/plans/0121.

closes #55

Brummel 9339279181 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.

Brummel 078c39a76a iter prep.2-term-new-construct (DONE 4/4): Term::New AST + Form-A surface + checker + drift — closes #32
Second iteration of the kernel-extension-mechanics milestone. Ships
the `new` Form-A keyword + `Term::New { type_name, args: Vec<NewArg> }`
AST variant + `NewArg::Type|Value` enum end-to-end through schema /
surface / checker, with two new diagnostics
(`NewTypeNotConstructible`, `NewArgKindMismatch`), a new arm in
prep.1's workspace-wide normalisation pre-pass `qualify_workspace_term`
that rewrites bare `Term::New.type_name` to qualified form
(symmetric to the existing `Term::Ctor` arm), and the data-model.md
+ form_a.md anchor additions. Codegen out of scope per spec; codegen
sites get `CodegenError::Internal` arms naming the raw-buf milestone
as the carrier.

Verification:

- `cargo test --workspace`: 654 tests passing, 0 failed.
- 3 new in-source checker tests pin the elaboration paths:
  `new_resolves_via_type_scope` (the spec's worked Counter example
  checks cleanly), `new_type_not_constructible` (missing `new` def
  in home module fires the new diagnostic), `new_arg_kind_mismatch_value_where_type`
  (kind-mismatch detection).
- 2 new schema-drift pins (`term_new_round_trips`,
  `term_new_type_arg_round_trips`) ratify the JSON byte shape:
  `{"t": "new", "type": "<TypeName>", "args": [{"kind": "type"|"value",
  "value": ...}]}`.
- 1 new surface round-trip pin exercises mixed-kind args through
  Form-A → JSON → Form-A.
- 44+ exhaustive Term-match sites across 24 files extended with
  `Term::New` arms — workspace-wide cargo build clean.

Concerns documented inline:

- `crates/ailang-core/tests/schema_coverage.rs` deliberately does
  NOT register `VariantTag::TermNew` in the `EXPECTED_VARIANTS`
  set. The coverage test asserts every declared variant is
  observed in the .ail fixture corpus; no .ail fixture in the
  current tree emits `"t": "new"` (codegen-runnable Term::New
  programs require the raw-buf milestone's plugin registry).
  Registering would fail the coverage check. The `visit_term` arm
  IS extended (compile-forced); only the enum registration is
  deferred. Inline rationale in the source. Future milestone that
  ships a Term::New fixture extends both sides.
- `crates/ailang-surface/src/print.rs` `write_term` Term::New arm
  was added in Task 1 (not Task 2 as planned), because without it
  ailang-core's tests fail to compile (the surface crate is in
  the dependency graph of ailang-core's test binaries). Task 2's
  round-trip pin verified the arm's correctness.
- Task 3 (synth elaboration) needed one implementer re-loop: the
  first attempt over-qualified within-module type-references via
  `qualify_local_types` on `new`'s signature when the home module
  was the calling module itself. Fixed by skipping qualification
  when `home_module == env.current_module`.

Architectural composition with prep.1: `Term::New` joins
`Term::Ctor` as a `type_name`-bearing site that goes through
`qualify_workspace_term`'s bare→qualified rewrite before the
checker sees it. The checker's `synth` arm for `Term::New`
therefore receives an already-qualified `type_name` (or a local
bare name for same-module construction).

Milestone status: kernel-extension-mechanics (Gitea #6) advances
2/3 iters. Next: prep.3 (kernel-tier modules + param-in), issue #33.

Brummel 832375f2ac convention: counter-prefix file naming across docs/specs/, docs/plans/, design/contracts/, design/models/
All 176 files in the four accumulating directories now use a
zero-padded 4-digit counter prefix that reflects creation order
(`NNNN-slug.md`). The counter is assigned per directory in strict
git-log creation order; ties broken alphabetically by original name.
The old `YYYY-MM-DD-` prefix on docs/specs/ and docs/plans/ files is
dropped — the date is recoverable from git log and the counter
carries the ordering.

A file's counter is stable for the life of the file: never reassigned,
never reused, never compacted. Deleted files retire their counter;
subsequent files do not fill the gap. This is the property that lets
cross-references stay literal — refs use the full filename including
the counter (`design/contracts/0007-honesty-rule.md`) so they grep
cleanly and resolve directly without a glob step.

313 cross-references updated across .md/.rs/.toml/.c/.json files
(test pins, include_str! paths, design-INDEX entries, baseline notes,
runtime C comments, inter-contract markdown links incl. bare basename
and `../models/foo.md` forms).

CLAUDE.md gets a new "File-naming convention" section spelling out
the rule and rationale. skills/brainstorm/SKILL.md and
skills/planner/SKILL.md updated so new spec/plan creation produces
counter-prefixed names from the start.

The full test suite (cargo test --workspace) passes.

Brummel 176821c2e7 iter design-md-rolesplit.1 (DONE 9/9): DESIGN.md -> design/ ledger role-split
The 3020-line docs/DESIGN.md is replaced by the design/ ledger:
design/INDEX.md (sole addressable spine, typed Contracts+Models tables,
polymorphic links — prose file OR authoritative source //!), 14
design/contracts/*.md test-linked invariants + 3 source-link-only
contracts (mangling/env-construction/qualified-xref, no prose file —
code is SoT), 5 design/models/*.md whitepapers, and
docs/journals/2026-05-19-design-decision-records.md (the
relitigation-guard archive — every why/rejected/does-not-do/rollback/
empirical ### moved out at ###-granularity). Clean cut: git rm
docs/DESIGN.md, no stub.

RED-first crates/ailang-core/tests/design_index_pin.rs — the 4-clause
anti-regrowth spine (DESIGN.md-gone / every-INDEX-link-resolves /
every-contract-names-a-resolvable-ratifier /
contracts-carry-no-decision-record-prose) — demonstrably RED before,
GREEN after. Build-atomic by task ordering: design_schema_drift.rs's
include_str! (the only compile-time consumer) retargeted to
design/contracts/data-model.md BEFORE the deletion; its
## Data model/## Pipeline slicer dropped (a simplification the split
enables). 2 NoInstance diagnostics + 2 lockstep E2Es retargeted to
design/contracts/{float-semantics,typeclasses}.md. ~12 agent reading
lists + 5 SKILL bodies + CLAUDE.md + skills/README.md + ~25
code/C/.ail/spec comment xrefs retargeted; OQ7 dangling 'Iter 13b'
cite deleted (no forward target — a pointer would be fiction).
honesty-rule.md rewritten so the rule names the new home
(rationale->journals), resolving the recon-found internal
contradiction; the two docs_honesty_pin.rs:70,72 pinned phrases kept
verbatim+contiguous.

Brummel e809f45e67 iter form-a.tidy: form_a.md class/instance/constraints + 3 documentary drift items
Six-task post-fieldtest documentary tidy. No production-code behaviour
changes; 559 tests green at every per-task gate.

T1-T3: form_a.md additions
- §Definitions intro "Three kinds" -> "Five kinds".
- New `### Class — (class ...)` subsection: EBNF carries optional
  superclass (0 or 1 per ClassDef.superclass schema), method
  signatures with optional defaults; anchored to
  examples/test_22c_user_class_e2e.ail (ok 24/2).
- New `### Instance — (instance ...)` subsection: EBNF carries the
  (method NAME (body LAM-TERM))* shape; canonical-form CLASS-REF
  rule explicitly stated (bare same-module / qualified cross-module);
  two examples — same-module abbreviated from
  mq3_class_eq_vs_fn_eq_classmod.ail and cross-module qualified
  from show_user_adt.ail; bare-cross-module-class-ref diagnostic
  named inline.
- §Types `(forall ...)` line extended with optional `(constraints
  (constraint CLASS-REF TYPE)+)?` clause; explanatory paragraph
  added with no-instance diagnostic anchor; fifth example added
  to the Examples block anchored to cmp_max_smoke.ail.

T4: docs/specs/2026-05-13-form-a-default-authoring.md "seven
carve-outs" → "eight carve-outs" at 6 sites contradicting the
§C4(b) compile-time-embed amendment (commit 9fcda8b). Sites:
preamble line 11, §C1 line 170, §C2 line 191, §C3 line 218,
§"Data flow" lines 363 + 374. Post-edit grep returns 4 surviving
"seven" lines (233, 238, 463, 469), all correctly §C4(a)-scope
or arithmetic/future-state.

T5: crates/ailang-core/src/hash.rs:50-57 — delete empty
`#[cfg(test)] mod tests {}` placeholder + 6-line relocation
comment. Tests live in crates/ailang-core/tests/hash_pin.rs
since form-a.1 T5; placeholder served no purpose. hash_pin.rs
still 10/10 passing.

T6: crates/ailang-surface/tests/round_trip.rs — module-level
`//!` and inner `///` docstrings rewritten to the post-T10
four-property framing (parse-determinism / idempotency /
CLI-pipeline-idempotency / carve-out-anchor) instead of the
retired Direction-1/Direction-2 language. Sibling-crate
breadcrumbs added pointing at the other two enforcement points
(roundtrip_cli.rs, carve_out_inventory.rs).

Drift item B2 (audit-form-a "plan file two sites") dropped per
recon verification: docs/plans/2026-05-13-iter-form-a.1.md
contains zero defective "seven" sites; all four hits are
internally scoped to §C4(a), arithmetic, or future-state.

Brummel 9fdc4cacff 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.

INDEX.md appended with the full iter summary covering T1-T12 (the
T1-5 commit at 77b28ad deferred the INDEX line to full-iter close).

Milestone [Form-A as the default authoring surface] structurally
closed. The compile-time-embed carve-out (prelude.ail.json) is
the subject of the queued follow-up milestone [Prelude embed:
Form-A as compile-time source]. audit-form-a runs as the next
dispatch.

Brummel 77b28ad64d 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.

Brummel 72e54f4fd3 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.

Brummel 44c6e56a0a audit-rt: milestone close — Direction-2 5th test + roadmap entry retired + wording sync
Milestone-close audit found three drift items (architect) plus
two carry-on items; bench all-green.

Fixes (rt.tidy, boss-direct):
- 5th test parse_then_print_then_parse_is_idempotent_on_every_ailx_fixture
  enforces Direction 2 of the Roundtrip Invariant directly. The
  DESIGN.md enforcement list grows from four to five tests.
- docs/roadmap.md P1 'Round-trip completeness invariant' entry
  retired with one-line journal mirror per roadmap convention.
- DESIGN.md wording sync: <16-hex> → <16-lowercase-hex> for the
  Float-bits-hex spelling in the new section (matches §Data model).

Milestone closed clean; five workspace-wide tests anchor the
.ail.json ↔ .ailx bijection plus AST-variant coverage.

Brummel 098fa7e9be 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.

Brummel 057784934a iter 22b.1.3: registry coherence-check fixtures + tests
Adds seven fixtures under examples/test_22b1_* exercising the
workspace-load coherence checks plus four positive/negative tests in
ailang-core/src/workspace.rs:

- iter22b1_instance_in_class_module_loads_clean: positive case;
  test_22b1_orphan_class.ail.json declares Show + instance Show Int
  in the same module (the class's). Registry has one entry.
- iter22b1_orphan_instance_fires_diagnostic: declares Show in
  test_22b1_orphan_third_classmod, declares instance Show Int in
  test_22b1_orphan_third (a third module). Fires OrphanInstance.
- iter22b1_duplicate_instance_fires_diagnostic: per the JOURNAL hint,
  module A defines class Show + instance Show MyInt (legal, A is
  class's module), module B defines type MyInt + instance Show MyInt
  (legal, B is type's module). Entry imports both. Fires
  DuplicateInstance with first/second_module distinct.
- iter22b1_missing_method_fires_diagnostic: class Eq with two
  non-default methods (eq, ne), instance Eq Int specifies only ne.
  Fires MissingMethod { method: "eq" }.

The surface round-trip gate (ailang-surface/tests/round_trip.rs)
filters out test_22b1_* fixtures because the Form-B parser arms for
ClassDef/InstanceDef are deferred to 22b.4. Without the filter, every
fixture's printed text would re-parse-fail on the unknown `class` /
`instance` head.

Test count: 291 → 295 (4 new workspace tests, all green).

Brummel 706f90bacd Iter 14c: ailang-surface ships — form (A) parser + pretty-printer
Strictly additive new crate per Decision 6 architectural pin.
JSON-AST stays the source of truth; ailang-surface is one
producer/consumer of ailang_core::ast::Module values. ailang-check
and ailang-codegen unchanged.

Crate contents:
- src/lex.rs (~264 LOC): 3-rule lexical core. Whitespace and parens
  delimit tokens; semicolon to EOL is comment; first-character
  classifier (digit -> int, " -> string, else -> ident).
- src/parse.rs (~1041 LOC): hand-written recursive descent. One Rust
  fn per EBNF production. No parser-combinator dep.
- src/print.rs (~371 LOC): deterministic pretty-printer. Round-trip
  contract with parse() is the surface's correctness gate.
- tests/round_trip.rs (~128 LOC): integration test runs every
  examples/*.ail.json fixture through print -> parse -> canonical
  JSON, asserts canonical-byte equality with the original.

Two AST-driven form widenings beyond the 14b sketch (both folded
into DESIGN.md Decision 6):
- lam-term carries (typed name type) params, ret type, and
  optional effects (Term::Lam has parallel param_tys/ret_ty/
  effects fields).
- import-clause admits (import name (as alias)?) (Import.alias
  is Option<String>).

Production count ~28, under 30-rule budget. Constraint 1
(formalisable for foreign LLM) intact.

Verification:
- cargo build --workspace green.
- cargo test --workspace: 76 tests green (was 64; +9 surface unit,
  +2 round-trip integration). All 17 fixtures round-trip
  byte-identical at canonical level. 3 hand-written .ailx
  exhibits parse to canonical JSON identical to their .ail.json
  siblings.
- cargo doc --no-deps zero warnings (DESIGN.md item 6 invariant).

Manual smoke test (ail parse → ail run): hello, box,
list_map_poly all produce expected output through the form-(A)
authoring lane end-to-end.

CLI: ail parse <file.ailx> [-o <file.ail.json>]. .ail.json
remains a first-class input to every existing subcommand.

Plan 14d: stdlib (std_list.ailx with length/filter/fold/concat/
reverse/head/tail), authored in form (A) from day one.
