From 6c28f103c59ee3a460ff596e9a1c266b3c3b0532 Mon Sep 17 00:00:00 2001 From: Pulkit Pareek Date: Fri, 29 May 2026 16:22:40 +0530 Subject: [PATCH 1/6] wire real Groth16 prover + camera scan + smoke runbook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three pieces that together move the ADR 0023 registration ceremony from "plumbing demo" to "drive end-to-end against a real phone": 1) RealRegistrationProver.kt — implements ProofGenerator using the existing IsolatedMobileProver (snarkjs in the sandboxed :prover process per ADR 0010). Builds a RegistrationUnlockedCredential from the per-install 32-byte secret with: biometricSecret = secret as decimal field element salt = 0 (reserved for StrongBox salt per ADR 0018) commitment = Poseidon(secret, salt) didHash = Poseidon(commitment) single-arg, binds DID to commitment in the proof's hash chain The prover runs against the same identity_proof v1.2 circuit as the W3 sign-in flow — no circuit change needed. publicSignals[1] is NOT bound to the issued challenge_nonce at the circuit layer (V1 limitation per ADR 0023); replay defence remains the single- use verify_code chain + 15-min TTL + per-IP rate-limit. Circuit v1.3 in Phase 1 Sprint 4 will bind the challenge in the public inputs. Wired in RegistrationScreen's viewModelFactory so production uses the real prover. StubProofGenerator stays as a test seam. 2) RegistrationQrCamera.kt — lean CameraX + ML Kit composable focused on registration deeplinks (zeroauth://reg?...). Handles the permission_pending / permission_denied / scanning states. First non-empty barcode latches and calls onResult; subsequent frames are dropped. Wired into RegistrationScreen as a "Scan with camera" button next to the existing paste field — the operator picks either input mode. The composable is intentionally NOT a refactor of ScanScreen.kt — that one carries the W3 proof-pairing state machine and isn't trivially reusable. The duplication is ~150 lines and compartmentalises the regression risk. 3) docs/operations/three-qr-signup-deployment.md + scripts/smoke-registration.sh — runbook + executable smoke test that validates the four documented HTTP round-trips against a deployed backend in <10s. The smoke checks: - POST /v1/registrations issues a well-shaped pair_code - pair-device returns next.step=enroll + valid enroll_code - submit-commitment returns next.step=verify + 32-hex challenge - complete with stub proof correctly surfaces 404 verify_failed (server's verifier rejected — plumbing reaches the verifier) The script is documented as pilot-grade — the real-proof verify step requires a real phone running the APK with the camera flow from item (2) above. Verify: - Bash syntax check: bash -n scripts/smoke-registration.sh OK - Android compile + emulator smoke run on CI for items 1 + 2. - Backend tests are unchanged (this commit only adds Android + docs + a bash script). --- .../android/ui/reg/RealRegistrationProver.kt | 139 +++++++++++ .../android/ui/reg/RegistrationQrCamera.kt | 227 ++++++++++++++++++ .../android/ui/reg/RegistrationScreen.kt | 69 ++++-- docs/operations/three-qr-signup-deployment.md | 200 +++++++++++++++ scripts/smoke-registration.sh | 165 +++++++++++++ 5 files changed, 782 insertions(+), 18 deletions(-) create mode 100644 android/app/src/main/java/dev/zeroauth/android/ui/reg/RealRegistrationProver.kt create mode 100644 android/app/src/main/java/dev/zeroauth/android/ui/reg/RegistrationQrCamera.kt create mode 100644 docs/operations/three-qr-signup-deployment.md create mode 100755 scripts/smoke-registration.sh diff --git a/android/app/src/main/java/dev/zeroauth/android/ui/reg/RealRegistrationProver.kt b/android/app/src/main/java/dev/zeroauth/android/ui/reg/RealRegistrationProver.kt new file mode 100644 index 0000000..de03c15 --- /dev/null +++ b/android/app/src/main/java/dev/zeroauth/android/ui/reg/RealRegistrationProver.kt @@ -0,0 +1,139 @@ +package dev.zeroauth.android.ui.reg + +import android.content.Context +import dev.zeroauth.android.prover.Groth16Proof +import dev.zeroauth.android.prover.GenerateInput +import dev.zeroauth.android.prover.IsolatedMobileProver +import dev.zeroauth.android.sec.Poseidon +import dev.zeroauth.android.sec.UnlockedCredential +import dev.zeroauth.android.ui.reg.RegistrationViewModel.ProofGenerator +import java.math.BigInteger + +/** + * Real Groth16 prover wiring for the ADR 0023 verify step. + * + * Builds a [RegistrationUnlockedCredential] from the per-install + * 32-byte secret + zero salt + commitment + DID, then hands it to + * the existing [IsolatedMobileProver] which runs snarkjs inside the + * isolated `:prover` process per ADR 0010. + * + * The witness shape matches what the W3 proof-pairing flow uses, so + * the same `identity_proof.circom` v1.2 circuit verifies registration + * proofs without any circuit changes: + * + * biometricSecret = secret as field element + * salt = 0 (we don't use a salt in V1; the slot is + * reserved for a future StrongBox-backed salt + * per ADR 0018) + * commitment = Poseidon(secret, salt) + * didHash = Poseidon(commitment) — single-arg Poseidon + * so the DID is bound to the commitment in the + * proof's hash chain + * sessionNonceHex = challenge_nonce from QR3 + * + * The prover computes: + * didHashSession = Poseidon(didHash, sessionNonce) + * identityBinding = Poseidon(secret, didHashSession) + * publicSignals = [commitment, didHashSession, identityBinding] + * + * The server's verifyProofOffChain runs snarkjs.groth16.verify + * against the boot-pinned vkey; on success the row flips to + * `completed`.

The tenant's signup page (or the dashboard's `/demo/registration`) calls `POST /v1/registrations` to open a session and gets back a one-time `pair_code`. The phone scans QR1 (encoding `zeroauth://reg?step=pair&session=…&code=ZA-XXXX-XXXX`), POSTs to `/v1/registrations/pair-device` with the code + a hardware fingerprint, and the server flips the row to `awaiting_commitment`. The phone captures the biometric locally, computes a Poseidon commitment, scans QR2, and POSTs to `/v1/registrations/submit-commitment` with the (did, commitment) pair — the biometric never leaves the phone. The server then mints `verify_code` + a 128-bit challenge nonce baked into QR3. The phone re-captures the biometric, produces a Groth16 proof using `IsolatedMobileProver` (the snarkjs WebView per ADR 0010), and POSTs to `/v1/registrations/complete`. The server runs `verifyProofOffChain`, asserts `publicSignals[0]` equals the stored commitment, creates a `tenant_user` row, and the ceremony terminates `completed`. Every state transition writes a hash-chained audit row. + +## Step 1 — Backend (already deployed) + +Already live at `https://zeroauth.dev`. To confirm: + +```bash +curl -fsS https://zeroauth.dev/api/health +# expect: { "status": "ok", ... } + +curl -fsS -X POST https://zeroauth.dev/v1/registrations \ + -H "Authorization: Bearer za_live_" \ + -H "Content-Type: application/json" \ + -d '{"profile":{"name":"Smoke Test","email":"smoke@example.com"}}' \ + | jq . +# expect: { "session": { "id": "...", "state": "awaiting_device", ... }, +# "pair": { "code": "ZA-XXXX-XXXX", "expires_at": "...", "deeplink": "zeroauth://reg?..." } } +``` + +If the POST returns a 401 the tenant API key is wrong.
