-// Repro: letrec sibling bindings nil after perform/resume in browser kernel
-//
-// Bug: After a CEK IO suspension (perform / hs-wait) resumes in the
-// WASM browser kernel, calling a sibling letrec binding could return
-// nil, with the error surfaced as `[sx] resume: Not callable: nil`.
-//
-// Root cause: cek-run / cek_run_iterative raised
-// `"IO suspension in non-IO context"` when a tree-walked eval_expr
-// (sf_letrec init exprs / non-last body, macro body, qq unquote, scope
-// body, provide body, dynamic-wind) hit a perform. The CEK suspension
-// was created correctly but never propagated through the OCaml-side
-// _cek_io_suspend_hook, so the outer driver never saw VmSuspended.
-//
-// Fix: cek_run / cek_run_iterative now invoke _cek_io_suspend_hook on
-// suspension (raising VmSuspended for the outer driver). When the hook
-// is unset (pure-CEK harness), they fall back to the legacy error.
-//
-// This test exercises the WASM kernel through K.callFn — the path that
-// browser event handlers use. Suspension surfaces as a JS object with
-// {suspended, request, resume(result)} that the test drives synchronously.
-//
-// Companion: spec/tests/test-letrec-resume-treewalk.sx tests the
-// CEK-only path through the OCaml test runner.

-⍝ Conway's Game of Life — toroidal one-liner
-⍝
-⍝ The classic Roger Hui formulation:
-⍝   life ← {⊃1 ⍵ ∨.∧ 3 4 = +/ +/ ¯1 0 1 ∘.⊖ ¯1 0 1 ⌽¨ ⊂⍵}
-⍝
-⍝ Read right-to-left:

-⍝   ¯1 0 1 ⌽¨ ⊂⍵      : produce 3 horizontally-shifted copies
-⍝   ¯1 0 1 ∘.⊖ …      : outer-product with vertical shifts → 3×3 = 9 shifts
-⍝   +/ +/ …           : sum the 9 boards element-wise → neighbor-count + self
-⍝   3 4 = …           : boolean — count is exactly 3 or exactly 4

-⍝   - all else → dies

-⍝
-⍝ For complex c, the Mandelbrot set is { c : |z_n| stays bounded } where
-⍝   z_0 = 0, z_{n+1} = z_n² + c.
-⍝ Restricting c (and z) to ℝ gives the segment c ∈ [-2, 1/4]
-⍝ where the iteration stays bounded.

-⍝ Rank-polymorphic batched-iteration form:

-⍝     count ← count + alive                  ⍝ tally surviving iters

-⍝   c=-1     : 100  (cycles 0,-1,0,-1,...)
-⍝   c=-2     : 100  (settles at 2 — boundary)

-; APL transpile / AST evaluator
-;
-; Walks parsed AST nodes and evaluates against the runtime.
-; Entry points:
-;   apl-eval-ast    : node × env → value
-;   apl-eval-stmts  : stmt-list × env → value (handles guards, locals, ⍺← default)
-;   apl-call-dfn    : dfn-ast × ⍺ × ⍵ → value   (dyadic)
-;   apl-call-dfn-m  : dfn-ast × ⍵ → value       (monadic)
-;
-; Env is a dict; ⍺ stored under "alpha", ⍵ under "omega",
-; the dfn-ast itself under "nabla" (for ∇ recursion),
-; user names under their literal name.

-# lib/guest/conformance.sh — shared, config-driven conformance driver.
-#
-# Usage:
-#   bash lib/guest/conformance.sh <conf-file>
-#
-# The conf file is a bash file that sets:
-#   LANG_NAME           e.g. prolog
-#   PRELOADS=( ... )    .sx files to load before any suite (path from repo root)
-#   SUITES=( ... )      colon-separated entries; format depends on MODE
-#   MODE                "dict" or "counters"
-#   COUNTERS_PASS       (counters mode) global symbol for the pass counter
-#   COUNTERS_FAIL       (counters mode) global symbol for the fail counter
-#   TIMEOUT_PER_SUITE   (optional, counters mode) seconds per suite, default 120
-#   SCOREBOARD_DIR      (optional) defaults to lib/$LANG_NAME
-#
-# It may override the bash functions emit_scoreboard_json / emit_scoreboard_md
-# to produce the per-language scoreboard schema. Defaults are provided.
-#
-# Suite formats:
-#   MODE=dict       — "name:test-file:(runner-fn)"
-#                     The runner expression is evaluated and is expected to
-#                     return a dict with :passed/:failed/:total.
-#   MODE=counters   — "name:test-file"
-#                     Each suite is run in a fresh sx_server session: preloads
-#                     are loaded, then the test file, then counters are read.
-#                     The suite is treated as starting from counters (0, 0).
-#
-# Output:
-#   Writes $SCOREBOARD_DIR/scoreboard.json and $SCOREBOARD_DIR/scoreboard.md.
-#   Exits 0 if every suite is green, 1 otherwise.
