Record Amendments A2 and A3 to the modeling matrix - #77
Merged
Conversation
A2: Joern's propagator and summary categories move to unsupported activation — the first wave-M1 run measured FlowSemantic on the pinned 4.0.610 as additive over the default unmodeled-call pass-through, so a P or O result scores the engine's optimism rather than the model; NilSemantics stays genuinely load-bearing, so category Z remains scored. The preregistration's "no FlowMapping propagates nothing" justification is corrected where it appears. A3: Semgrep's sanitizer-selectivity cell becomes a template-level unsupported override — the mandated taint_assume_safe_functions option itself suppresses flow through the undeclared sanitizer-lookalike, making the cell's positive undecidable by construction; sanitizer-kill stays scored. Partition counts move to Bifrost 2 / Semgrep 5 / Joern 8 / CodeQL 12, with the amendment rationale carried verbatim in the retained unsupported reasons.

Summary
The two amendments surfaced by the first wave-M1 run (Python), recorded per the amendment contract and approved by the maintainer:
FlowSemanticon the pinned 4.0.610 is additive over the default unmodeled-call pass-through (probed: removing the declaration leaves the finding standing; positional mappings don't exclude undeclared positions; summary field-destinations are ignored). A P or O result would score the engine's optimism, not the model. Category Z stays scored —NilSemanticswas demonstrated genuinely load-bearing. The measured-false "no FlowMapping propagates nothing" justification is corrected in docs/adapters.md.taint_assume_safe_functions: true(which keeps propagator models load-bearing) itself suppresses flow through the undeclared sanitizer-lookalike, so sanitizer-selectivity's positive is undecidable by construction in one CE invocation. Sanitizer-kill stays scored.Scored-template counts: Bifrost 2 / Semgrep 5 / Joern 8 / CodeQL 12. The partition code carries both rationales verbatim in the retained unsupported reasons; the count-pinning and Semgrep-set tests updated; a new template-level override mechanism handles A3 (consulted before the category cell, same tag-proof discipline).
Doc-only + partition code; no fixtures, no runs, no corpus changes; no freeze binds any modeling report.
