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 18g tidy follow-up RED-test fixture: a let-binder whose
|
|
; value is a Term::Var referencing a non-Own fn-param must
|
|
; inherit the param's mode for codegen's drop-emission gates.
|
|
;
|
|
; The carve-out documented in 18d.4's Iter A fix: the gate
|
|
; checks `scrutinee_is_owned` against `current_param_modes`,
|
|
; but only fn-params are recorded there. A let-binder aliasing
|
|
; an Implicit-mode fn-param passes the gate (its lookup
|
|
; misses, default = owned), so the arm-close drop fires on
|
|
; memory the caller still references.
|
|
;
|
|
; Pattern: `pin_aliased` takes `t` as Implicit-mode (default,
|
|
; no annotation); aliases it via `(let a t ...)`; matches `a`.
|
|
; In the TNode arm the pattern-bindings `l` / `r` would be
|
|
; dec'd at arm close because `a` looks owned to the gate —
|
|
; corrupting the caller's tree.
|
|
;
|
|
; Pre-fix under --alloc=rc: refcount underflow at the second
|
|
; iteration of `loop`, where the recursive call into
|
|
; `pin_aliased(t)` re-loads cells the previous iteration
|
|
; freed.
|
|
; Post-fix: clean exit, output `0`. Stats are not the focus
|
|
; here (the caller's tree leaks under the Implicit-mode
|
|
; back-compat lane); the test asserts only correctness.
