## Ops

| Method | Path | What |
|--------|------|------|
| GET | `/v1/health` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/health` | Liveness. Does not increment download KV. |
| GET | `/v1/doctor` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/doctor` | Richer liveness: hash-commitment attest, refuse list. Does not increment download KV. |
| POST | `/v1/commit` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/commit` | SHA-256 commitment of salt+witness. Witness is not returned. Not a SNARK. |
| POST | `/v1/attest` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/attest` | Bind a public statement to a commitment. Refuses a posted witness. |
| POST | `/v1/open` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/open` | Check a commitment opening the caller already holds. Reveals; not a ZK proof. |
| POST | `/v1/verify` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/verify` | Recompute a public attest receipt hash. Does not recover a witness. |
| GET | `/v1/limitation` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/limitation` | Honesty labels: REAL hash commitment; SLOT for Groth16/SNARK. |
| GET | `/v1/skill` · `https://aziel-runtime.vibelock.workers.dev/p/zkattest/skill` | Return ZKAttest skill markdown. Does not increment download KV. |
