| FR # | Description | Acceptance Criteria | |------|-------------|----------------------| | FR‑01 | Device‑bound key pair generation – When a user enrolls, a public/private key pair is generated on the device (Secure Enclave / TPM). | • Private key never leaves the device.
• Public key stored in the user profile (encrypted at rest). | | FR‑02 | Session token issuance – Every API request while in exclusive mode must include a JWT signed with the device private key, containing a nonce and timestamp. | • Server validates signature, nonce freshness (< 30 s).
• Rejected requests return 401 – Spoof Attempt. | | FR‑03 | Replay protection – Nonces are stored in a short‑lived cache (e.g., Redis) per user. | • Duplicate nonce → request denied.
• Cache TTL = 5 min. | | FR‑04 | Biometric + hardware verification – Activation requires biometric (FaceID/TouchID) and hardware attestation (SafetyNet/Apple DeviceCheck). | • Both factors must succeed; otherwise activation fails. | | FR‑05 | Audit log – Every exclusive‑mode action is logged with: user ID, device ID, signed token, operation, outcome. Logs are immutable (append‑only, signed). | • Logs can be exported in CSV/JSON.
• Log entries are tamper‑evident (hash chain). | | FR‑06 | UI – “Exclusive Mode” toggle – Accessible from the Settings page for premium users only. | • Toggle shows green “Active” state with timer countdown.
• Inactive state shows grey with “Upgrade to Premium”. | | FR‑07 | Grace period & re‑authentication – After 30 min of inactivity, the mode auto‑locks and requires re‑authentication. | • Timer visible in UI.
• On lock, user sees “Re‑authenticate to continue”. | | FR‑08 | Feature flag – Controlled via our LaunchDarkly/FeatureHub system. | • Can enable per‑region, per‑user segment. | | FR‑09 | Fallback – If device cannot generate keys (old OS), show a friendly error with upgrade guidance. | • No silent failures. | sechexspoofy156 exclusive

| NFR # | Category | Requirement | |-------|----------|-------------| | NFR‑01 | Security | All keys use at least 256‑bit ECC (e.g., P‑256). Private keys are stored in hardware‑backed keystore. | | NFR‑02 | Performance | Token validation < 5 ms; end‑to‑end request latency ≤ 250 ms. | | NFR‑03 | Scalability | System must handle 10 k concurrent exclusive sessions per region. | | NFR‑04 | Reliability | 99.9 % availability of the validation service (redundant instances behind load balancer). | | NFR‑05 | Compliance | Data‑in‑transit encrypted TLS 1.3; data‑at‑rest encrypted with AES‑256. | | NFR‑06 | Observability | Metrics: activation count, failure reasons, latency, replay‑attempt rate. Exported to Prometheus + Grafana. | | NFR‑07 | Usability | Activation flow ≤ 2 clicks; total time ≤ 5 seconds on modern devices. | | NFR‑08 | Internationalization | UI strings localizable (i18n). | | Item | Description | |------|-------------| | Feature
