a call to rt.new_k / rt.recycle_leaf with a constant class, or to rt.own,
does its class-list pop or push (or owner store) inline and goes on after
the call; an empty list, memdebug, a held range, a block outside memory, a
translated word or a type/class mismatch takes the ordinary call. in a
region this replaces the o3_invoke round trip. o3 frees of leaf objects now
use recycle_leaf too (new_k stamps the type inside o3 since b86db60).
ZYNOFASTALLOC=1 turns it off; ZYPERFMAP=1 writes a perf map of translated code.
tests/programs/o3_freelist.zc: reuse, zeroing, an empty list, untyped
neighbours, memdebug; jit vs ZYNOFASTALLOC vs ZYO3INTERP.
prover: do not restore length facts after a call-loop2026-10-15T01:55:58+00:00zinczinc@downsta.ir2026-10-15T01:55:58+00:00urn:sha1:a6e52065bb7eaee3bbef5a1c3f879c616e3d24bc
Restoring undirtied lafacts when the body might free was wrong: push can
grow an array without dirtying its name, so a[99] after push warned against
a stale length 0. Keep the old lafact_keep rule; reorder explain_prover so
the constant/affine cases run before the touch() loops.
prover: len/cross-array/fixed-new/affine proofs; keep facts past call loops2026-10-15T01:53:36+00:00zinczinc@downsta.ir2026-10-15T01:53:36+00:00urn:sha1:fe43cc41876ffdb3e714de8efc8a2907d456b5db
Rebased the prover WIP onto main. lafact_keep restores undirtied allocation
facts even when the loop body might free (so a later touch() no longer drops
every length fact). proven_p uses ptr_still so an outer call keeps the check.
entry_fact still supplies the size for the "might free" explain reason.
bounds_prover.zc and explain_prover.zc land with test.sh coverage.
wip: prover gaps (inline len bound, cross-array, rt.new depth, fixed new, affine i*n+k); unbuilt and untested2026-10-15T01:47:02+00:00zinczinc@downsta.ir2026-10-14T17:16:17+00:00urn:sha1:a1d546cc74a72abc4973bf96f72bbd529320d711
