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.

; Bench fixture: explicit-mode pair of bench_list_sum.
|
|
;
|
|
; Same algorithm and same sizes as bench_list_sum.ail (build a list of
|
|
; 0..N-1, sum it, print) but with full `(borrow)` / `(own)` annotations
|
|
; on every fn-param signature in the hot path. Under --alloc=rc the
|
|
; codegen now emits `inc`/`dec` instructions: each cell allocated by
|
|
; `cons_n_acc` is dec'd as `sum_list_acc` walks the chain.
|
|
;
|
|
; The IntList is `(drop-iterative)` so the param drop on the LCons arm
|
|
; stays O(1) stack regardless of length — without this, dec-ing a
|
|
; 3M-cell chain at scope close would recursive-overflow.
|
|
;
|
|
; This is the "RC-fair" arm of the cross-language bench (21'f);
|
|
; pairs with bench/reference/list_sum_explicit_free.c which adds
|
|
; matching free() calls. Together they answer "what does RC's full
|
|
; alloc+dec cost look like vs C's full malloc+free cost?".
|
|
;
|
|
; Sizes match bench_list_sum exactly:
|
|
; 100_000 * 24 B = 2.4 MB
|
|
; 1_000_000 * 24 B = 24 MB
|
|
; 3_000_000 * 24 B = 72 MB
|
|
;
|
|
; Expected stdout (one int per line):
|
|
; 100_000 -> 4999950000
|
|
; 1_000_000 -> 499999500000
|
|
; 3_000_000 -> 4499998500000
