python3 -c "
import os, re
from collections import defaultdict

VAULT = '/var/lib/hermes/workspace/m3ta-brain'
md_files = []
for root, dirs, files in os.walk(VAULT):
    if '.git' in root or '.obsidian' in root: continue
    for f in files:
        if f.endswith('.md'):
            md_files.append(os.path.relpath(os.path.join(root, f), VAULT))

# Build index
paths = set(md_files)
broken = []
for f in md_files:
    with open(os.path.join(VAULT, f)) as fh:
        for i, line in enumerate(fh, 1):
            for m in re.finditer(r'\[([^\]]+)\]\(([^)]+\.md)\)', line):
                target = m.group(2)
                if target.startswith('http'): continue
                resolved = os.path.normpath(os.path.join(os.path.dirname(f), target))
                if resolved not in paths:
                    broken.append((f, i, target))
print(f'Broken links: {len(broken)}')
