Post-fieldtest documentary tidy. Six tasks: T1-3 add three new
sections to crates/ailang-core/specs/form_a.md (Class, Instance,
Constraints on polymorphic fns) anchored against the live corpus
(test_22c_user_class_e2e for class-decl, show_user_adt +
mq3_class_eq_vs_fn_eq_classmod for instance, cmp_max_smoke for
constraints), each with EBNF + canonical-form-rule paragraph +
verified example. T4 fixes 5 contradictory "seven carve-outs"
sites in docs/specs/2026-05-13-form-a-default-authoring.md (the
audit-form-a journal flagged 3 sections; recon expanded to 5
total). T5 deletes the empty mod tests {} placeholder + its
6-line explanatory comment in crates/ailang-core/src/hash.rs
(form-a.1 T5 relocated the unit tests; placeholder serves no
purpose). T6 rewrites round_trip.rs module + inner test
docstrings to use the post-T10 four-property framing
(parse-determinism + idempotency + CLI-pipeline-idempotency +
carve-out-anchor) instead of retired Direction-1/Direction-2
language.
Drift item B2 (plan-file "seven carve-outs") dropped from this
iter per recon: the docs/plans/2026-05-13-iter-form-a.1.md file
contains zero defective sites; all four "seven" mentions are
internally scoped to §C4(a), arithmetic, or future-state. The
audit-form-a journal "two sites" claim does not match what is
in the plan file at HEAD.
All tasks are pure docs/comment changes. cargo test --workspace
stays at 559 green at every task boundary.
