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 4e8447d15d iter 24.tidy: close 5 actionable drift items from audit-24
Documents the three iter-24.3 strengthenings as load-bearing
invariants and tightens two error-handling sites:

T1: DESIGN.md gains new subsection §Cross-module references in
synthesised bodies (between Resolution-and-monomorphisation and
Defaults-and-superclasses) documenting three invariants installed
in iter 24.3 — (1) MonoTarget::FreeFn::type_args carries canonical
types post-collection via normalize_type_for_lookup; (2) post-mono
synthesised body cross-module refs may bypass the source template's
import_map (codegen falls back to module_user_fns / module_def_ail_types);
(3) FreeFnCall synth pushes one ResidualConstraint per declared
forall-constraint with rigid vars substituted by fresh metavars.

T2: codegen_import_map_fallback_pin.rs (integration test) asserts
the synthesised prelude.print__<IntBox> body references
show_user_adt.show__<IntBox> AND prelude module's imports do not
contain show_user_adt — proving the cross-module ref bypasses
import_map at codegen.

T3: polyfn_dot_qualified_branch_pin.rs (integration test) asserts
bare-name print f (f : Int -> Int) fires exactly one no-instance
diagnostic at typecheck with zero unknown-variable diagnostics —
proving the bare-name resolution reaches the dot-qualified synth
branch where the constraint-residual push fires.

T4: check/lib.rs:2858 unwrap_or_default() replaced with .expect()
carrying the registry-coherence message — class_methods index
drift now surfaces explicitly rather than rendering NoInstance
with an empty method name.

T5: mono.rs gains apply_subst_and_normalize helper (Option<Type>
return) extracted from two byte-identical call sites at
collect_mono_targets and collect_residuals_ordered. Each call site
retains its own rigid-var / unit-default policy in the None arm
(site 1: rigid → has_rigid+break, unbound → Type::unit; site 2:
non-concrete → Type::unit). Byte-identity invariant on mono-symbol
hashes enforced by construction.

Tests: 558 passed (was 556 + 2 new pins). No production semantic
change — pure documentation + test pin + error-handling tightening
+ helper refactor. bench/cross_lang exit 0; bench/compile_check +
bench/check exit 0 this run (latency.implicit_at_rc / latency.explicit_at_rc /
bench_list_sum.bump_s noise envelope unobserved, lineage continues
at 10th consecutive observation without firing this run).
