Issues

• F32 NaN payload and sign canonicalize to 0x7FC00000 on the interpreter and JS lanes; C preserves bits (F32.bits of bit-flipped ±inf: 0x7F800001/0xFF800001 vs 0x7FC00000 for both) — #797 persists + interpreter

• One term, two types, all gates green: presentation-dependent double typing from the #1190 shared-cell merge (v2.0.36)

• v2.0.36 --verdict certifies a different program than it checked/ran (let-convoy, incl. new nested shapes; #1368 fix unreleased)

• An Array of a concrete function type (Array<(U32 -> U32)>) checks and runs on the interpreter but stops both emitters with "an open Array element type" (follow-on to #1130)

• A Nat match with N literal-numeral rows costs ~quadratic checker memory: 2000 rows → 1.4 GB, 3000 → 3.6 GB (a valid program that runs); succ-pattern rows cost 83 MB

• bend f.bend -o <binary> leaks one empty /tmp/bend-XXXXXX directory per failed emission (missing foreign import, or no main to run)

• bend <page>.html -o <dir> exits 0 with a 0-byte JS chunk when the page's .bend import is missing or check-failing (the loader never runs)

• Metal: one ! over a two-leaf fork tree (a 365-fork spine beside a 3-fork spine) faults; each leaf alone, a balanced 365+365, and --gpu off all pass
