Core Functionality

1. Query Parsing & Suggestion Engine

   • When a user types a query and pauses > 500 ms, the backend returns 0‑5 filter suggestions.
   • Each suggestion includes:
     • Filter type (date, numeric, enum, tag, custom)
     • Human‑readable label (e.g., “Date: Last 30 days”)
     • Estimated result count (rounded to nearest 10).
   • Suggestions must be relevant to ≥ 80 % of a random sample of 100 queries (measured in an internal QA script).

2. Automatic Application

   • Clicking a suggestion applies the filter instantly.
   • The UI shows a temporary banner: “Filter “Date: Last 30 days” applied – [Undo]”. The banner disappears after 8 seconds or on Undo.

3. Undo Flow

   • Undo restores the previous filter state (including any manual filters the user had set).
   • Undo is a client‑side operation with no additional server round‑trip.

4. Saved Smart‑Searches

   • Users can click “Save” on any active query+filter combo.
   • Saved searches appear in a dropdown under the search bar, with a star icon.
   • Deleting a saved search removes it from the user’s profile (soft‑delete for audit).

5. Feature Flag

   • Controlled by a LaunchDarkly flag smart-search.enabled.
   • The flag can be scoped per‑organization.

4. User Stories (ordered by priority)

| # | As a … | I want … | So that … | |---|--------|----------|-----------| | US‑01 | Product marketer | A “New Notification” wizard that asks for channel, audience filter, schedule (date‑time or recurring), and message template | I can launch a campaign without developer help | | US‑02 | Product marketer | Time‑zone aware scheduling (auto‑detect from user profile) | Recipients receive the message at a sensible local hour | | US‑03 | Product marketer | Dynamic token insertion (first_name, plan_type, last_login) | Messages feel personal, driving higher CTR | | US‑04 | Product marketer | Delivery throttling (max 3 per user per 24 h, 10 per week) | We avoid spamming and stay under compliance limits | | US‑05 | Customer Success | Audit log showing who created/modified a schedule, timestamps, and version diff | We can investigate any delivery issues or compliance queries | | US‑06 | Data Engineer | Metrics endpoint (/notifications/metrics) exposing sent, delivered, opened, click‑through counts per schedule | We can monitor campaign health in our dashboard | | US‑07 | QA Engineer | Test harness to simulate time‑zone based deliveries & throttling | Automated regression coverage | SONE-071

6️⃣ Roadmap to Market

| Timeline | Milestone | |--------------|---------------| | 2024 Q4 | Scale‑up pilot production (10 kg batches) at DOE’s Oak Ridge National Laboratory (ORNL). | | 2025 H1 | First‑partner demonstration with Fluence Energy (grid‑storage prototype, 1 MWh). | | 2025 H3 | Automotive pilot with Rivian (prototype EV pack, 120 kWh). | | 2026 Q2 | Submission of US Patent 12,345,678 (solid‑state Na‑NASICON electrolyte). | | 2026 Q4 | Start of large‑scale roll‑to‑roll sintering line (≥ 1 ton/month). | | 2027–2028 | Commercial launch, targeting $30–$45 kWh⁻¹ for stationary systems. |

6. Non‑Functional Requirements

| NFR # | Requirement | |-------|-------------| | NFR‑01 | Scalability – Scheduler must support up to 500k active schedules and 10 M deliveries per day. Use partitioned tables + sharded Redis for throttling counters. | | NFR‑02 | Availability – 99.9 % SLA for the Scheduler API (5 xx errors < 0.1 %). Deploy across two AZs. | | NFR‑03 | Latency – API response < 200 ms for CRUD ops; delivery worker latency < 5 s from scheduled time to provider call. | | NFR‑04 | Security – Data at rest encrypted (AES‑256); transport TLS 1.2+. Auditable actions stored immutably (WORM). | | NFR‑05 | Compliance – Support GDPR “right to be forgotten”: deleting a user must also purge any pending scheduled notifications for that user. | | NFR‑06 | Observability – Structured logs (JSON) with correlation IDs; tracing via OpenTelemetry. | | NFR‑07 | Testing – 80 % unit coverage, 70 % integration coverage, end‑to‑end UI tests with Cypress. | | NFR‑08 | Performance – Bulk audience resolution (≤ 10 k users per batch) must complete in < 2 s. | Core Functionality

Technical Execution and Direction

S1 deploys its usual high-grade technical team here:

• Cinematography: The lighting is moody but not dark, using high-contrast shadows to emphasize Ogawa’s facial expressions. The camera lingers on her hands—clenching, unclenching—as much as on the physical action.
• Sound Design: Diegetic sounds (rustling clothes, footsteps, a buzzing phone) are amplified, while the non-diegetic score is minimal, creating a sense of oppressive intimacy.
• Pacing: The director uses long, uninterrupted takes during the initial confrontation scenes, allowing Ogawa to build tension naturally. The more explicit content, when it arrives, feels like an inevitable culmination of the narrative pressure, not a disconnected sequence.
