be26f77410 apl: Phase 3 reshape ⍴ / transpose ⍉ — 27/27 structural tests green
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Has been cancelled
Details 
Add apl-reshape (dyadic ⍴, cycling), apl-transpose (monadic ⍉, reverse
axes), apl-transpose-dyadic (dyadic ⍉, permutation), plus helpers
apl-strides / apl-flat->multi / apl-multi->flat.

lib/apl/tests/structural.sx: 27 new tests covering ravel, reshape,
monadic/dyadic transpose across scalar/vector/matrix/3-D cases.

test.sh now runs structural.sx via its own inline framework (skips
stale tests/runtime.sx which targeted a pre-Phase-2 list-based API).

912de5a274 phase-22 APL: runtime.sx vectors/bitwise/sets/reduce/format
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 34s
Details 
lib/apl/runtime.sx (60 forms):
- Core: apl-iota (1..N), apl-rho (shape), apl-at (1-indexed access).
- Rank-polymorphic apl-dyadic/apl-monadic helpers: scalar×scalar,
  scalar×vector, vector×vector all supported uniformly.
- Arithmetic: add/sub/mul/div/mod/pow/max/min, neg/abs/floor/ceil/sqrt.
- Comparison: eq/neq/lt/le/gt/ge → 0/1 result vectors.
- Boolean: and/or/not on 0/1 values, element-wise.
- Bitwise: bitand/bitor/bitxor/bitnot/lshift/rshift — element-wise.
- Reduction: reduce-add/mul/max/min/and/or; scan-add/mul.
- Vector ops: reverse, cat (scalar/vector catenate), take (±N), drop (±N),
  rotate, compress (boolean mask), index (multi-index).
- Set ops: member (∊, → 0/1), nub (∪, unique preserve-order),
  union, intersect (∩), without (~). All use SX make-set internally.
- Format (⍕): vector → space-separated string, scalar → str.

lib/apl/tests/runtime.sx + lib/apl/test.sh: 73/73 pass.

4f4b735958 apl: array model + scalar primitives Phase 2 (+82 tests) 
Implement lib/apl/runtime.sx — APL array model and scalar primitive library:
- make-array/apl-scalar/apl-vector/enclose/disclose constructors
- array-rank/scalar?/array-ref accessors; apl-io=1 (⎕IO default)
- broadcast-monadic/broadcast-dyadic engine (scalar↔scalar, scalar↔array, array↔array)
- Arithmetic: + - × ÷ ⌈ ⌊ * ⍟ | ! ○ (all monadic+dyadic per APL convention)
- Comparison: < ≤ = ≥ > ≠ (return 0/1)
- Logical: ~ ∧ ∨ ⍱ ⍲
- Shape: ⍴ (apl-shape), , (apl-ravel), ≢ (apl-tally), ≡ (apl-depth)
- ⍳ (apl-iota) with ⎕IO=1 — vector 1..n

82 tests in lib/apl/tests/scalar.sx covering all primitive groups;
includes lists-eq helper for ListRef-aware comparison.

da8ba104a6 apl: right-to-left parser + 44 tests (Phase 1, step 2)
Some checks failed
Test, Build, and Deploy / test-build-deploy (push) Failing after 17s
Details 
Implement lib/apl/parser.sx — APL expression parser:
- Segment-based algorithm: scan L→R collecting {fn,val} segments
- build-tree constructs AST with leftmost-fn = root (right-to-left semantics)
- Handles: monadic/dyadic fns, strands (:vec), assignment (:assign)
- Operators: derived-fn (:derived-fn op fn), inner product (:derived-fn2)
- Outer product ∘.f (:outer), dfns {:dfn stmt...}, guards (:guard cond expr)
- split-statements is bracket-aware (depth tracking prevents splitting inside {})

44 new parser tests + 46 existing tokenizer = 90/90 green.
