fizzgig__auth_flow_trace

traces every protected route back to its auth check + verifies webhooks.

heuristic auth-flow audit. Flags protected-shaped routes (/admin, /dashboard, /account, /api/admin, /api/private) without detectable auth gating — pass files with `// path`-style markers and it names the exact unprotected handler files (per-file attribution) rather than a blanket verdict; webhook routes without signature verification (stripe constructEvent / crypto.createHmac / svix); auth library drift (mixing next-auth + clerk + supabase + auth0 + iron-session + lucia in one source).

caught a policy that would have leaked every user's comments. shipped a fix in 4 minutes.

works great. one false positive on a join table — easy to ignore.
