…H-MATCH-001 (SPEC §86.6 closure) Codifies the INV-INIT-ARCH-MATCH-001 invariant authored as runtime code in PR #1760 (`validate_init_arch_matches_tensor_evidence` in aprender-train::train::pretrain_real). Adds: - FALSIFY-INIT-ARCH-MATCH-001: integration falsifier bound to the unit-test family `cargo test -p aprender-train --lib inv_init_arch_match_001` (7 tests covering: canonical §86 reject, inverse reject, matching qwen2 accept, matching llama accept, None metadata skip, unmappable metadata skip, GGUF-unknown tensor skip). - INV-INIT-ARCH-MATCH-001 proof_obligation: safety invariant — when both metadata.architecture and tensor-name-inferred family resolve to concrete distinct slugs, gate MUST fail-fast before any training step. No false-positive when either side returns "unknown". ## Salvage path The error message includes an inline `apr stamp` recipe (PR #1757): ``` apr stamp <pre-p0k.apr> --architecture qwen2 --hf-architecture Qwen2ForCausalLM \ -o <stamped.apr> apr pretrain --init <stamped.apr> ... ``` ## Refs - PR #1742 (PMAT-690 P0-K base — producer-side stamping) - PR #1750 (P3-A `apr inspect --quality` — surfaces hf_identity=0/20 pre-stamp) - PR #1754 (SPEC §85 P2-E findings — context) - PR #1757 (apr stamp HF identity extension — salvage path) - PR #1758 (SPEC §86 amendment — defect specification this contract closes) - PR #1760 (INV-INIT-ARCH-MATCH-001 runtime implementation) - memory/feedback_upstream_metadata_masquerade.md (methodology #33) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
