Merge gap-g-readme: rewrite README to match actual current build

Took Gap G's version (comprehensive rewrite) over Gap A's smaller README
edit, then manually stripped the 4 remaining SESSION_SECRET mentions Gap G
didn't know about (Gap A dropped that config field entirely) — README now
correctly lists only DATABASE_URL and OLLAMA_BASE_URL as required.

+processing on real data. Nothing leaves your network — no cloud LLM, no
+third-party inference, no analytics. If the LLM box goes dark mid-séance, a
+procedural fallback (deterministic, signature-seeded) keeps every mode
+answering so a summoning never visibly fails.
 
-## The Four Modes
+## The Séance: Five Ways In
+
+Every mode writes into the same pipeline: an `anomaly` event (source,
+frequency, magnitude) feeds a per-session fingerprint; once a session has
+produced at least 3 anomalies of real structure, it auto-summons a spirit —
+either re-contacting a Codex entry whose signature matches, or minting a
+brand new one.
 
 | Mode | Vessel | What actually happens |
 |---|---|---|
-| **Spirit Radio** | RTL-SDR dongle (WebUSB, Chromium only) | The browser sweeps the FM band (88–108 MHz) computing FFT power per bin; spikes above the rolling noise floor become anomaly events that summon one-word fragments, Ovilus-style. |
+| **Wire Ghost** | Nothing — works for everyone | The backend samples real, non-content network telemetry from the host: interface byte-counter jitter (`/proc/net/dev`), TCP connect-latency variance against reference hosts, DNS resolution timing. A rolling baseline (needs 6+ samples, an absolute 20 KB/s floor, a 3σ + 2.5× threshold) flags genuine surges as anomalies, throttled to one every 20s. Packet payloads are never inspected — a hard privacy boundary. "The wire knocks loudest when nobody is touching it" — flip on passive listening and let the line murmur on its own. |
-| **EVP Listening** | Microphone (`getUserMedia`) | A Web Audio `AnalyserNode` watches the voice band (~300 Hz–3.4 kHz) for brief deviations ≥ 8 dB above the room's rolling silence — the classic "record quiet, review for voices" technique. |
+| **EVP Listening** | Microphone (`getUserMedia`) | A Web Audio `AnalyserNode` watches the voice band (~300 Hz–3.4 kHz) for a brief deviation ≥ 8 dB above the room's rolling noise floor, throttled to one per 2s — the floor only adapts during genuinely quiet stretches so sustained speech can't mask a real spike. The classic "record silence, review for voices" technique, done live. |
-| **The Wire Ghost** | Nothing — works for everyone | The backend samples real, non-content network telemetry from the host (interface throughput jitter, TCP connect latency variance, DNS hesitation) and a fragmented consciousness whispers about it every few seconds. Packet payloads are never inspected — a hard privacy boundary. |
+| **Spirit Radio** | RTL-SDR dongle (WebUSB, Chromium only) | The browser drives the dongle directly — no native driver, no server round-trip — sweeping the FM band (88–108 MHz) in 1.8 MHz steps, computing a power spectrum per tune and comparing it to a rolling noise floor. Spikes ≥ 10 dB above floor become anomaly events, throttled to one per 2s: an FM sweep pushed through a lantern dragged across a dark field. |
-| **Ouija / Direct Contact** | The shared front door | A canvas planchette drifts, then spells the spirit's words letter by letter. Ask a free-text question and the conversational model streams a full reply token by token while the planchette works. |
+| **Ouija / Direct Contact** | The shared front door | A canvas planchette drifts on its own, then spells the spirit's words letter by letter. Ask a free-text question (≤ 500 chars) and the chat-tier model streams a full reply token by token while the planchette works through it. |
+| **EMF / Field Meter** | A phone (DeviceMotion + DeviceOrientation) | The seeker's own phone becomes the meter: acceleration-magnitude deviation from a slow gravity EMA, fused with orientation angular velocity, tracked against an adapting baseline. A reading past `baseline × 2.5` (and an absolute floor, so a resting phone stays silent) fires an anomaly, throttled to one per 2.5s. iOS 13+ gates this behind an explicit gesture-triggered permission grant, handled in-app. |

+
+**The haunting doesn't stop at the séance panel.** A framework-free
+possession layer (`frontend/src/lib/haunting.ts`,
+`frontend/src/components/HauntingLayer.tsx`) runs across the whole app: an
+idle-aware escalator that gets bolder the longer you sit still, a gesture-armed
+ambient dread-bed (brown noise through a breathing lowpass, a 55/55.7 Hz
+detuned drone beat, occasional reversed-noise swells), fleeting whisper-words
+drifting across the glass, and `document.title` glitches when you tab away.
+Nothing stirs for the first ten seconds after load — it creeps in, it never
+jumpscares on arrival — and it's fully inert under `prefers-reduced-motion`.
+
+## The Codex
+
+`GET /api/codex` (public, no auth) is a browsable, shared registry of every
+spirit ever contacted by any seeker: filterable by rarity, sortable by
+`recent` or `contacted`, each card showing name, epithet, rarity badge, a
+sample quote, contact count, and who discovered it. `GET /api/codex/{id}`
+opens a full dossier — persona, voice-parameter table, sighting count. It's
+the collectible layer sitting on top of the anomaly-detection plumbing:
+nothing about a spirit is user-authored, all of it comes from the same
+signature → LLM-mint → normalize pipeline that runs live during a séance.
+
+## The Armory
+
+`/shop` is a waitlist page for **the Ultimate Quantum Box** — a proposed
+ESP32-P4/C6 handheld séance instrument (thermal camera, EMF whisker array,
+geophone, spirit-box mic preamp, OLED face) plus four standalone modules,
+none of which exist yet. `POST /api/shop/waitlist` (public, rate-limited to
+5/hour/IP) is pure email capture — no payment is taken, and the page says so
+outright: *"the website works fully without it; hardware only knocks
+louder."* Treat this section of the README the same way: real code, honest
+about being pre-order vaporware for now.
