STEM BIO-AI Local Audit Report

Target: Runchuan-BU/BioClaw Execution Mode: LOCAL_ANALYSIS Calibration Profile: default (ca-policy-1.0, mirror_only, authoritative_release) Calibration Effect: mirror-only in 1.7.8 — selected profile metadata is surfaced in artifacts, but authoritative scan scoring still follows deterministic runtime constants. Preview-only posture changes, including Stage 4 replication emphasis, do not change the formal score until a future read-through phase. Use stem policy simulate to preview governed score deltas and posture changes. Final Score: 60 / 100 Formal Tier: T2 Caution Use Scope: Research reference and supervised non-clinical technical review only.

Audit Freshness

Review After: 45 days Expires On: 2026-07-05 Change-triggered re-audit recommended now: False Current re-audit reasons: none Trigger examples: git_commit_changed, readme_or_docs_claim_surface_changed, dependency_manifest_changed, dataset_or_model_reference_changed

Reasoning Diagnostics

Diagnostic-only heuristic stem-bio-ai-reasoning-v1.3.2 (uncalibrated_initial_priors_pending_benchmark_calibration); lane consistency heuristic_consistent (0.825), uncertainty band low_spread (0.178), risk heuristic within_heuristic_gate (0.4525), confidence envelope 0.537-0.663. This heuristic layer does not override the final score.

Regulatory Traceability Assistant

Regulatory basis note Aligned to: EU AI Act (Regulation (EU) 2024/1689), ICH M15 (Step 4, Jan 2026), AIRI (MIT, 2024), FDA QMSR, FDA AI-enabled device guidance themes, and IMDRF SaMD/GMLP frameworks — as of Jun 2026. This is a traceability aid, not a compliance or clearance determination.

Stage 1

  • EU_AI_ACT_ARTICLE_13 — signal_only (mapping confidence: weak, evidence strength: weak)
    • Boundary, intended-use, and limitation language is relevant to transparency scaffolding only.

Stage 2R

  • IMDRF_CLINICAL_CONTEXT_BOUNDARY_SIGNAL — signal_only (mapping confidence: weak_moderate, evidence strength: weak)
    • Repository-local contradiction and boundary signals are relevant to clinical-context traceability, not clinical validation.

Stage 3

  • EU_AI_ACT_ARTICLE_10 — signal_only (mapping confidence: weak, evidence strength: moderate)
    • Provenance and bias signals are relevant to data-governance review, but do not verify execution quality.

Stage 4

  • EU_AI_ACT_ARTICLE_12 — partially_aligned (mapping confidence: moderate, evidence strength: weak)
    • Reproducibility and trace manifests support record-keeping scaffolding, not operational logging completeness.

Summary: Structural signals partially align with traceability scaffolding. This remains a pre-audit traceability aid, not a compliance determination.

AIRI Coverage

Examples of Covered AIRI Risks
