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.

; Iter 18d.3 — move-aware pattern bindings: let-close emits an
|
|
; inlined per-field dec sequence that skips moved slots and dec's
|
|
; non-moved (wildcarded) pointer-typed slots.
|
|
;
|
|
; Fixture shape:
|
|
; - Pair carries two `IntList` fields (both pointer-typed).
|
|
; - main builds a Pair, pattern-matches it binding only the FIRST
|
|
; field, wildcarding the SECOND.
|
|
; - The matched binding `a` is consumed by `sum_list`. The
|
|
; wildcarded slot is logically retained by `p` (no binder owns
|
|
; it), so at p's let-close it must be dec'd.
|
|
;
|
|
; Expected IR shape under --alloc=rc at p's let-close:
|
|
; - NO `call void @drop_pat_extract_partial_drop_Pair(ptr <p>)`
|
|
; (the uniform drop fn is replaced by inline partial drop)
|
|
; - YES a `getelementptr ... ptr <p>, i64 16` + `load ptr` +
|
|
; `call void @drop_pat_extract_partial_drop_IntList(ptr <slot1_v>)`
|
|
; (slot 1 was NOT moved → emit per-field dec)
|
|
; - YES `call void @ailang_rc_dec(ptr <p>)` (outer cell)
|
|
; - NO load+dec for slot 0 (moved → skipped)
|
|
;
|
|
; Expected stdout: 6 (1 + 2 + 3 = 6, sum of the first list).
