PTO ISA v0.58.2
PTO ISA v0.58.2 closes the audited decision-to-ASL gaps and publishes the exact merged specification at 652e9b5bbee2ffea8917f9caa8c6e87be99fe05c.
Highlights:
- bit-exact B.FPATR matrix post-processing and TCVT FP16/BF16/FP32 to E8M0 profile semantics
- corrected Tile dtype-family legality, regular TLSU assigned types, integer IndexTile domains, Shared state behavior, and precise memory preflight
- exact numeric-format descriptors and finite decompositions
- refreshed ASL-generated documentation, independent AVS points, traceability, and release evidence
Exact-head release verification succeeded across identity, lightweight contracts, strict normative model, all 8 ASL pages, fail-closed aggregation, and final validation:
