+\section{Methodology}
+
+
+\subsection{Problem Formalization}
+
+Mathematical formalization of agent-induced pricing distortions. Formal definition of potential loss mechanisms $\alpha D$
+
+We consider a business across time during which we have an evolving vector $p_t \in \Re^N$ where $N$ is the number of products in our catalogue. our price vector is directly dependent on a demand function $q_t$ which we define as a linear method of a price elasticity matrix $B_t$. This is the same setup that Microsoft created in their research.
+
+We gether interaction data from users interacting with a sample platform simulating a hotel/airline which generates interaction distributions $I_t = \{(p_t, q_t^\text{obs}, \pi_t)\}_{t=1}^T$
+
+
+\subsection{Cost of Information Framework}
+
+Mathematical demonstration and validation of the COI and citation backed evidence, and framework overview + show harm to user via other cost distortions. Maybe split into 3.2.1 (COI Theory) and 3.2.2 (Framework Design)

 - /components/ is gonna have ui/ which defines things like Button, Card, DatePicker with generic definitions and any tracking or observation code. We then define feats/airline/ and feats/hotel/ as children of components with specific components like AirlineHero and HotelCard.
 - in /styles/ we define airline.css and hotel.css to tailor accents and styling for each.

+## How to Run
+
+```sh
+# install deps
+npm install
+
+# set store mode (hotel or airline)
+export STORE_MODE=hotel
+
+# run dev server
+npm run dev
+```
+
+Server runs on `http://localhost:3000`
+
+## Environment Variables
+
+| Variable | Description | Default | Example |
+|----------|-------------|---------|---------|
+| `HOSTNAME` | Server hostname | `localhost` | `localhost` |
+| `STORE_MODE` | Mode switch for platform | `hotel` | `hotel` or `airline` |
+| `NEXT_PUBLIC_API_BASE` | Public API base URL | `http://localhost:3000` | `http://localhost:3000` |
+| `NEXT_PUBLIC_APP_ENV` | Application environment | `dev` | `dev`, `prod` |
+| `NEXT_PUBLIC_HOVER_THRESHOLD` | Hover dwell threshold (ms) | `1200` | `1200` |
+| `BACKEND_URL` | Backend service URL | `http://localhost:5000` | `http://localhost:5000` |
+
+## Routes
+
+### Public Pages
+- `/` — Landing page (mode-aware root)
+- `/hotel` — Hotel mode landing
+- `/hotel/products` — Hotel catalog
+- `/airline` — Airline mode landing
+- `/airline/products` — Flight catalog
+- `/admin/experiments` — Experiment management UI
+
+### API Routes
+- `GET /api/session` — Fetch or create session, sets httpOnly cookie

+- `POST /api/ingest` — Ingest event to Kafka via backend
+- `GET /api/admin/experiments` — List all experiments
+- `POST /api/admin/experiments/start` — Start new experiment for session
+- `POST /api/admin/experiments/stop` — Stop experiment by ID
+
+## Event Catalog
+
+All events are ingested via `POST /api/ingest` and follow the `EventBase` schema. Below are the 17 canonical events:
+
+| Event Name | Category | Payload Example |
+|------------|----------|-----------------|

+## Architecture
+
+### Route Groups
+- `(hotel)` — Hotel mode pages
+- `(airline)` — Airline mode pages
+- `api/*` — API routes (session, pricing, ingest, admin)
+
+### Middleware Flow
+1. Request arrives at Next.js
+2. Session middleware checks for `phantom_session_id` cookie
+3. If missing, `/api/session` mints new session + sets cookie
+4. Store mode (`STORE_MODE` env) determines rendered page variant
+5. Client-side components fetch pricing via `/api/pricing`
+6. User interactions emit events to `/api/ingest` → Kafka
