v1.0.1 — X Quantum Dublin demo build

Hotfix rebuild — 2026-05-29. Same v1.0.1, fresh APK with the on-device fixes below. Install over the existing v1.0.1 (same signing key, data preserved).

Hotfix — 2026-05-29

• Privy embedded-wallet recovery & signing fixed — PrivyElements is now mounted so the embedded wallet's UI/unlock can render; signMessage no longer hangs on user-signer:sign. The deterministic note-seed is persisted in SecureStore, so recovery runs offline on every boot instead of re-hitting the remote wallet WebView.
• Transaction serialization fixed — the @noble/curves v2 migration had broken Transaction.serialize() (every on-chain op threw undefined is not a function); the Hermes shims now point at the real v2 module paths.
• C3 merkle_path STARK verifier fixed — verify_constraints_merkle_path treated the 32 padding rows (480–511) as active Poseidon rounds, rejecting valid V3 unshield proofs with InvalidProof (deterministic per note). Verifier rebuilt and redeployed on devnet (DGY37k…, slot 465731409).
• Resilience — transient RPC network retry + ephemeral crash-sweep with fresh balance.
• Build — pnpm 10 monorepo Android autolinking workaround.

Verified end-to-end on device (devnet): shield, emergency unshield + sweep, private merchant subscribe, and the classic local-keypair flow.

Dublin demo build, submitted to the X Quantum hackathon (Dogs Patch, 2026-05-24).

Highlights

• p01_quantum_wallet scaffold (Phase A) — first cut of the post-quantum smart-contract wallet program (STARK-authorized), groundwork for the full PQ end-to-end plan.
• Mobile quantum wallet UX layer (Phase B) — boot scaffold + WalletSigner abstraction so the wallet path is keypair / Privy agnostic.
• Real-time progress bars across subscribe / shield / unshield / confidential / cancel.
• License key card on the subscription detail screen.

Fixes (Dublin)

• stark gen_proof JSON output: commitment now quoted as a string (avoids JS number-precision truncation on the mobile side).
• STARK proof generation timeout bumped 60s → 180s for slower Android devices.
