+## Native ABI Evidence Packet Matrix
+
+`scripts/native_abi_evidence_packet.sh --gate` aggregates the
+`native-abi-proof` compiler-output suite into
+`native-abi-evidence.json` and `native-abi-evidence.md`. The packet is the
+representative material type-lowering gate for PRs and release sweeps.
+
+| Gate row | Evidence | Required proof |
+|---|---|---|
+| Native ABI correctness | `tests/test_native_abi_contract.sh` and `tests/test_c_layout_pod_records.sh` retained native-rep artifacts | runtime output passes and required ABI/materialization tokens are present |
+| Native-region artifact chain | retained HIR, LLVM before opt, LLVM after opt analysis, object disassembly, compile plans, and native-rep JSON | artifacts exist, structural safety checks pass, semantic checksum checks pass |
+| Explain-lowering accounting | native-rep rows summarized into boxes, unboxes/coercions, dynamic fallbacks, barrier decisions, typed native records, and runtime counter summaries | typed/control material accounting rows pass |
+| Runtime safety | `perry-runtime native_async` tests | required native async/rooting test names pass and appear in logs |
+| Release/LTO symbols | `scripts/check_runtime_symbols.sh` over the runtime archive | runtime archive defines all sentinel symbols |
+
+The material accounting rows compare
+`native_abi_packet_typed.ts` against `native_abi_packet_control.ts`.
+The gate requires 100% elimination of boxed-number allocations, Buffer
+slow-path helpers, and typed-array/Uint8Array slow-path helpers in the typed
+packet; at least 95% fewer traced allocations and traced write barriers; at
+least 75% fewer static write-barrier helper sites; at least 25% fewer static
+runtime helper call sites; at least 2.0x median wall-time speedup; and at least
+1.5x p95 wall-time speedup. The control packet must keep positive boxed,
+helper, barrier, allocation, and runtime-call baselines, and both packets must
+produce matching semantic checksums so the optimized path and fallback path are
+comparing the same work.
+
 The `hir_fact_rewrite` fixture is the rewrite-insensitivity gate for the HIR
 fact layer. It keeps `const j = helper(i); dst[j] = ...` on the same direct
 buffer path as an inline index expression: inbounds GEPs, bounds assumptions,
