Brummel 2ee97943bd iter loop-recur.tidy GREEN: reject lambda-captures-loop-binder at check + milestone-close audit resolution
GREEN side of the RED audit-trail commit 39380d3. The loop/recur
milestone-close audit found a [high] correctness defect — a lambda
capturing a loop binder passed `ail check` then panicked
unreachable!() at codegen (crates/ailang-codegen/src/lambda.rs:102)
on type-correct input. Fixed symmetrically to mut.4-tidy: new
CheckError::LoopBinderCapturedByLambda (code
loop-binder-captured-by-lambda, bracket-free F2 Display), the
Term::Lam escape guard gained a parallel loop_stack pass. Minimal
mechanism: loop_stack element Vec<Type> -> Vec<(String,Type)> so
the already-threaded per-loop frame carries binder names; recur
still reads .1 by position (Boss-call-2 positional invariant
preserved verbatim — the name is a second field for the escape
guard only, a consumer iter-2 did not anticipate). Codegen
byte-unchanged (typecheck-only fix). carve_out 17->18 + ct1-F2 +
DESIGN.md note lockstep.

Folded in (Boss-side, audit resolution): the two [medium]
doc-honesty edits the audit surfaced (mut_var_allocas rustdoc now
states its mut-var+loop-binder dual use; Term::Loop doc-comment
now describes the real shipped state, not iter-1's stale
"per-binder phi" forward-look) + a [low] P2 roadmap todo
(plan-recon undercount countermeasure, pairs with planner Step-5
items 7+8). Bench gate: all 3 scripts exit 0, 25 metrics 0
regressed — pristine, carry-on (no baseline/ratify).

cargo test --workspace 619 -> 622 / 0 red (Boss-reran
independently, hash_pin 11/0). The loop/recur milestone is
audit-clean; fieldtest is the only remaining step before close.

Brummel 1566ce0b29 iter loop-recur.2: typecheck semantics — binder typing, recur checks, verify_loop_body
Second of three iterations of the standalone loop/recur milestone
(plan 5ac57fe). Replaces the iter-1 synth CheckError::Internal stub
for Term::Loop/Term::Recur with real binder typing + positional
recur arity/type checking via a new loop_stack: &mut Vec<Vec<Type>>
frame threaded as mut.2's mut_scope_stack, a new private
verify_loop_body tail-position pass (sibling of the byte-frozen
verify_tail_positions — 0 deletions there), and the four Recur*
diagnostics firing point-exactly on four negative fixtures. The
iter-1 loop_sum_to.ail fixture now also typechecks clean; an
infinite loop typechecks (no termination claim). NO codegen (the
iter-1 lower_term stub stays — iter 3); NO Diverge/guardedness
(spec boundary).

Three Boss design calls implemented verbatim and journalled:
RecurTypeMismatch is an Assign-style structural pre-check (not a
unify-propagate); loop_stack is positional Vec<Type> (binder names
via ordinary locals); diagnostic-code precedence is by pass
ordering (no explicit logic).

Two DONE_WITH_CONCERNS, both journalled: a plan-ordering defect
(Task 2's compile gate forced the check_fn threading the plan
deferred to Task 4 — resolved byte-identically, only resequenced)
and the recurring mut.2-class recon-undercount of cross-module
synth callers (resolved via the plan's compile-sweep oracle).

Boss systemic fix folded in: planner SKILL.md Step-5 gains item 7
(compile-gate vs. deferred-caller ordering) so the plan-ordering
defect class is scrubbed at plan time. cargo test --workspace
608 -> 616 / 0 red (Boss-reran independently).

Brummel 1ff7e811af fix: mut-local diagnostics doubled the [code] prefix in human stderr (fieldtest F2)
The four mut-local CheckError variants (MutAssignOutOfScope,
AssignTypeMismatch, UnsupportedMutVarType, MutVarCapturedByLambda)
embedded the bracketed kebab code in their thiserror Display body,
while the non-JSON CLI formatter independently prepends [code] from
CheckError::code() — doubling it. Non-mut variants never embedded
the bracket; this brings the four in line with that convention.

RED-first via the debug skill: ct1_check_cli.rs pins the observable
property (code appears exactly once in the rendered human
diagnostic). GREEN was a trivial four-string mechanical edit.

Tests 598 -> 599.

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 0eb33235eb iter mq.1: class-ref canonical-form extension + workspace-internal class-name qualification
Three schema fields move bare → canonical (bare for same-module,
<module>.<Class> for cross-module): InstanceDef.class,
Constraint.class, SuperclassRef.class. Symmetric to ct.1's
Type::Con.name rule. ClassDef.name stays bare.

validate_canonical_type_names gains three field-walks via new
check_class_ref helper + two sibling diagnostics
BareCrossModuleClassRef / BadCrossModuleClassRef.
check_class_name_fields narrowed to ClassDef.name-only.

Workspace-internal class-name keys all qualified:
class_def_module, class_by_name, registry entries.0,
ClassMethodEntry.class_name, class_superclasses, mono's
class_index, Origin::Class.class_name. New qualify_class_ref
helper at workspace.rs scope plus sibling
qualify_class_ref_in_check in ailang-check.

Two new positive on-disk fixtures (mq1_xmod_constraint_class{,_dep})
exercise the qualified Constraint.class shape.

Recon claim that all existing fixtures' class-refs are intra-module
was empirically wrong — 10 fixtures required minimal canonical-form
migration. Duplicate-instance test architecturally restructured:
post-mq.1 orphan-freedom makes two-modules-on-same-(class,type)
structurally impossible; new test_22b1_dup_same_module fixture
lands both instances in the class's module.

Plan defects fixed inline: Origin::Class.class_name single
construction site (plan recon off-by-one); build_class_index in
mono.rs needed qualifying; build_module_globals needed Def::Instance
carve-out; check_fn declared-constraint matching needed inline
canonical-form lifting; NoInstance Float-aware message arm needed
prelude.Eq/prelude.Ord match; coherence type-leg needed qualified-
head split-and-lookup. Tasks 3-6 ran as one coherent fix.

7/7 tasks, 520 tests green. bench/compile_check.py + cross_lang.py
exit 0; bench/check.py exit 1 (4 improvements-beyond-tolerance,
audit-ratifiable, not a regression).

MethodNameCollision + dispatch path unchanged; iters mq.2 + mq.3
land them.

Brummel 79cc78507b iter ext-cli.1: CLI accepts .ail (Form A) sources alongside .ail.json
Closes the loop opened by this morning's .ailx → .ail rename. Every
path-taking ail subcommand (check, build, run, manifest, render,
prose, merge-prose, describe, emit-ir, diff, workspace, deps) now
accepts a .ail (Form A) input as well as .ail.json (Form B). For
.ail paths the subcommand parses through ailang_surface::parse
in-line and proceeds with the same loaded Module value .ail.json
would have produced; binary semantics are extension-agnostic.

Architecture: a new ailang_surface::{load_module, load_workspace}
pair dispatches on file extension. A new injection point
ailang_core::workspace::load_workspace_with<F> lets the surface
crate plug in an extension-aware loader without core having to
import surface (which would close a crate cycle). Import resolution
in workspace::visit now prefers a .ail sibling over a .ail.json
sibling. The CLI binary's 18 callsites switched to the surface
loaders. Surface parse failures route through
workspace_error_to_diagnostic as a new SurfaceParse variant of
WorkspaceLoadError, so `ail check --json foo.ail` on a malformed
.ail returns a parseable JSON diagnostic with code
surface-parse-error instead of the misleading
`json: expected value at line 1 column 1` fall-through.

Boss pre-commit correction: the implementer followed the plan
verbatim and used snake_case `surface_parse_error`, but every
existing diagnostic code in the codebase is kebab-case (verified
via `git grep` over crates/ailang-check/src and crates/ail/src);
realigned to `surface-parse-error` at three sites (the diagnostic
arm + two ct1 test strings). Journal Concerns section records
the correction.

Tests: cargo test --workspace 487 green (+7 from this iter:
1 core unit, 4 surface integration, 1 ail E2E pair, 1 ct1 CLI
diagnostic-shape). bench/check.py, compile_check.py, cross_lang.py
clean on re-run; the latency.{explicit,implicit}_at_rc tail
cluster occasionally flagged on first runs is the same
nondeterministic cluster the previous two audits documented;
baseline left pristine for the third consecutive iter.

Roadmap follow-up "ail check/build/run accept .ail extension" (P2)
removed.

DESIGN.md §Decision 6 / "CLI" bullet gained the symmetric upward
sentence: both .ail and .ail.json are first-class CLI inputs.

Brummel c1783e01bc iter ct.1.8: E2E coverage for canonical-form diagnostic surface + happy path
Five tests in crates/ail/tests/ct1_check_cli.rs, each pinning one named property:

- check_json_emits_bare_cross_module_type_ref: --json mode surfaces
  `bare-cross-module-type-ref` with non-zero exit on the
  test_ct1_bare_xmod_rejected fixture.
- check_json_emits_bad_cross_module_type_ref: same for
  `bad-cross-module-type-ref`.
- check_json_emits_qualified_class_name: same for `qualified-class-name`.
- check_human_mode_emits_actionable_message_to_stderr: human (non-JSON)
  mode prints both the offending type name and the migration-command
  hint to stderr — this path goes through the anyhow/thiserror Display
  impl, not workspace_error_to_diagnostic, so it needs its own pin.
- check_ordering_match_post_migration_is_clean: post-migration
  ordering_match.ail.json typechecks via the CLI with zero diagnostics,
  guarding against revert of the ct.1.5 migration or a regression in
  Registry::normalize_type_for_lookup that would reject the canonical form.
