Completed the FORTH-79 standard-dictionary cross-ISA exerciser campaign: all
9 identities (zuse, rajames/bob, 00-06) x all 3 architectures (amd64,
aarch64, riscv64), 27 legs total. No crashes, no heap corruption across the
full run -- real-world validation that the WIREBIND use-after-free fix
(commit 9142dda, FABRIC-3.md SXIII) holds under genuine multi-cycle load,
not just the synthetic repro used to verify it.
Cross-identity parity is perfect: 0 diffs across all 9 identities on each
architecture. Two real bugs found in double-precision (D.) output, reported
per this project's standing rule (report, don't fix without being asked):
- M* on a negative operand -> D. reports DOUBLE-OVERFLOW, universally
across all three architectures (engine-level bug, not arch-specific).
- D+ on two negative doubles -> D. reports DOUBLE-OVERFLOW on aarch64
only; amd64 and riscv64 both correctly print -2. cell_t width confirmed
64-bit on all three (ruled out as the cause); exact mechanism still open.
Also fixed a test-harness timing issue (run_identities.sh): the retry
budget for USE-after-attach was too tight for boots with several live VMs
already accumulated, causing false "FAILED to USE" verdicts on identities
that actually succeeded a few seconds later. Widened the budget and
switched to smaller per-boot batches (2-3 identities) as the reliable
pattern for this shape of campaign.
