# QUANTUMANCY

*an instrument for speaking with the dead bandwidth*

Quantumancy is a self-hosted séance. Point a browser at it and real sensing
channels — your microphone, your phone's motion sensors and magnetometer, an
RTL-SDR dongle, your own network's jitter, a paired ESP32 sensor node, or
just a text box — feed real anomaly detection into a locally-run LLM that
invents a spirit on the spot: a name, an epithet, a persona, a coherent
voice, hidden traits, a rarity tier, and a small immortality in a shared
registry called **the Codex**. A local Piper TTS then gives that spirit an
actual voice, degraded through a hand-built static-and-echo effects chain
until it sounds like it's coming through a dying radio.

And the physical world genuinely participates: every summon carries entropy
harvested from your room's own noise floors, tonight's **real moon phase**
skews who answers, NOAA's **measured geomagnetic K-index** thins the veil,
and unprompted speech is token-sampled with a seed derived from the room —
the room literally selects the words.

**This is an interactive horror art installation, not a paranormal claim.**
Every "entity" is fiction generated by a language model on your own
hardware — the system prompts are explicit about this (see
`backend/app/llm/prompts.py`). But every *measurement* is real: FFT power
spectra, magnetometer microtesla, `/proc/net/dev` counters, BLE signal
attenuation, published lunar ephemerides, NOAA space-weather data. The rule
(see `docs/CHANNELS.md`): the fiction may interpret a measurement however it
likes; it may never fabricate one. Nothing leaves your network except a
courteous 10-minute poll of NOAA's public Kp feed — no cloud LLM, no
analytics. If the LLM box goes dark mid-séance, a procedural fallback keeps
every mode answering so a summoning never visibly fails.

## The Séance: 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 — either
re-contacting a Codex entry whose signature matches (a real draw, not a
guarantee — see *The Room Decides*), or minting someone new.

| Mode | Vessel | What actually happens |
|---|---|---|
| **Wire Ghost** | Nothing — works for everyone | Real, non-content network telemetry from the host: byte-counter jitter (`/proc/net/dev`), TCP connect-latency variance, DNS timing, against a rolling baseline. Payloads are never inspected — a hard privacy boundary. Passive listening lets the line murmur on its own. |
| **EVP Listening** | Microphone (`getUserMedia`) | A Web Audio `AnalyserNode` watches the voice band (~300 Hz–3.4 kHz) for deviations ≥ 8 dB over the room's rolling noise floor — live spectrum scope, audible anomalies, and every frame feeds the entropy pool. Works everywhere, including iPhone. |
| **Spirit Radio** | RTL-SDR dongle (WebUSB, Chromium only) | The browser drives the dongle directly, sweeping FM 88–108 MHz, computing power spectra against a rolling floor. Every USB call is time-boxed (`withTimeout`) so a sulking dongle errors instead of hanging silently. |
| **Ouija / Direct Contact** | The shared front door | A canvas planchette wanders the full board, brushes letters, visits YES/NO, and rests on GOODBYE every few minutes; questions stream back token by token while it spells. |
| **EMF / Field Meter** | A phone | Where the Generic Sensor API exists (Chromium/Android), the **actual magnetometer** in microtesla — a true EMF meter, baseline-subtracting Earth's constant field. Everywhere else (including iOS), the motion-fusion fallback: acceleration deviation + orientation angular velocity. Both are real physics; `lib/baseline.ts` gives them one shared rolling-EMA core. |
| **The Vessel** | ESP32-P4 sensor node (LAN) | Paired hardware POSTs temperature/pressure/mic/radar readings; the Cold Spot Detector and the séance's DeviceWhisper panel render them live, and hardware anomalies can trigger a summon in an open séance. Firmware in `firmware/` — written and reviewed, **never yet flashed to a real board**. |

`lib/bluetooth.ts` (BLE RSSI as a presence field — bodies absorb 2.4 GHz)
is implemented and tested but not yet wired into a séance panel.

## The Room Decides

`backend/app/entropy.py` · `frontend/src/lib/entropy.ts` ·
`backend/app/celestial.py` · `backend/app/geomagnetic.py`

- **Physical entropy.** The client harvests noise from live sensor frames
  (mic and RF noise floors), Von Neumann–debiases it, SHA-256–conditions
  it, and sends it with every summon. The server treats it as untrusted by
  construction: every draw is `HMAC(fresh server secret, contribution ||
  context)`, so a hostile client can only ever *add* unpredictability,
  never steer an outcome. Whether a channel's familiar spirit answers again
  (`RETURN_CHANCE`) is one of these draws.
- **Real astronomy.** Moon phase from orbital mechanics (validated against
  published ephemeris dates, not against itself) and true solar midnight
  from the seeker's longitude (only the longitude is kept, never a full
  coordinate). A full moon roughly **triples** rare/mythic mint odds — a
  skew, never a gate — nudges hidden traits stronger and stranger, and
  erodes a familiar spirit's claim on its channel so strangers push
  through on thin nights.
- **Real space weather.** NOAA SWPC's planetary K-index, cached 10 minutes,
  never blocking: a geomagnetic storm measurably thins the veil, and the
  entity is told `Kp 6.33 — moderate geomagnetic storm` as a fact of its
  room.
- **Generation from nothing.** `SpiritService.manifest()` produces
  unprompted speech: the prompt contains no seeker input at all — only
  measured room state — and Ollama's sampling `seed` derives from the
  room's entropy. Change the noise, get different words. Rendered in the
  transcript as an intrusion (violet edge), not a reply.

## Rituals, Judgment, and the Reliquary

Every minted entity carries **hidden traits** (alignment / power /
volatility / deceptiveness) — signature-seeded ground truth the persona
prompt never sees, so the LLM cannot leak it. The séance offers:

- **The ritual** — a 4-sigil hold-to-charge rite; success reveals the
  entity's true traits, failure reveals nothing. Judgment is never gated on
  it: you may always judge blind.
- **Judgment** — trust / banish / test / cross over. Correct calls pay
  essence and favor; wrongly trusting a demon sharpens the haunting,
  wrongly banishing a benevolent spirit wounds it, and a correctly-judged
  stuck spirit **crosses over**: at peace, permanently retired from its
  channel, its signature freed for someone new.
- **The Reliquary** — essence (earned, never bought), item drops on
  milestone moments, purchasable unlocks, and hand-drawn sigils.
  `/shop` remains a waitlist for the **Ultimate Quantum Box** hardware —
  email capture only, no payment taken, and the page says so.

A **Ghost Log** HUD whispers entity tells app-wide, and `/log` is the
recallable record: your last séances with entity, counts, and echo lines.

## Coming In From the Cold

- **Guests:** `POST /auth/guest` mints a real `wanderer-xxxx` account and a
  normal session — the front door (`/enter`) offers it as *"slip through as
  a wanderer"*, and the séance nudges wanderers to claim a name so their
  codex outlives the mist.
- **Conditions:** `GET /api/conditions` (and the séance's side-column
  strip) surfaces tonight's moon, veil thinness, and geomagnetic state.
- **First contact:** each mode shows one in-fiction hint if its sensor sits
  unused, dismissible forever; error copy redirects instead of dead-ending
  (no mic? "the board needs no ear").
- **PWA:** a `manifest.webmanifest` makes it installable to a home screen
  (standalone, no service worker — an offline séance is meaningless).
- **Phones:** dedicated ≤560px and ≤380px layouts, 44px touch targets,
  16px inputs (so iOS Safari doesn't zoom-and-stick).

## Architecture

Two machines on the LAN, no containers anywhere:

```

- **App CT** — FastAPI serves the built Vite/React SPA, the REST API, the
  `/ws/session` séance and `/ws/device-feed` sockets, and `/audio/*` spirit
  WAVs. Postgres holds accounts, sessions, transcripts, the Codex, traits,
  essence/favor, inventory, sigils, devices, and the waitlist. Piper TTS is
  degraded through a numpy chain (rate → pitch → bitcrush → echo → static);
  eight **voice archetypes** (elder/young/child/drowned/burned/distant…)
  covary pitch/rate/noise/echo so two spirits sound like two different dead
  people, not two settings.
- **Ollama box** — two model tiers behind a bounded-concurrency queue; a
  full queue rejects with a themed `veil_crowded` error rather than hanging.
- **Cloudflare Tunnel** — terminates HTTPS; its secure context is what
  unlocks mic, WebUSB, and motion/magnetometer permissions.
- **systemd** — `Restart=always`, no start-limit surrender, wants Postgres:
  the veil survives reboots and crash bursts without a human.

## Quickstart

Prereqs on the App CT: Python 3.11+, Node 18+, Postgres (`apt`), and an
Ollama box on the LAN with the two model tiers pulled.

**1. Postgres** (one-time):

```bash
sudo apt-get update && sudo apt-get install -y postgresql
sudo -u postgres psql -c "CREATE ROLE quantumancy WITH LOGIN PASSWORD 'quantumancy';"
sudo -u postgres psql -c "CREATE DATABASE quantumancy OWNER quantumancy ENCODING 'UTF8' TEMPLATE template0;"
sudo -u postgres psql -c "CREATE DATABASE quantumancy_test OWNER quantumancy ENCODING 'UTF8' TEMPLATE template0;"
```

> `quantumancy_test` is dropped and recreated by every test run. Never point
> the app's own `DATABASE_URL` at it.

**2. Configuration:**

```bash
cp .env.example .env
# edit .env: confirm DATABASE_URL and OLLAMA_BASE_URL
```

**3. Backend:**

```bash
cd backend
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```

**4. Piper voices.** `backend/voices/` is gitignored; download each `.onnx`
plus its `.onnx.json` from
[rhasspy/piper-voices](https://huggingface.co/rhasspy/piper-voices):

| id | file | language | character |
|---|---|---|---|
| `lessac` | `en_US-lessac-low.onnx` | en | a measured American woman (default) |
| `amy` | `en_US-amy-low.onnx` | en | a soft American woman |
| `ryan` | `en_US-ryan-low.onnx` | en | a deep American man |
| `alan` | `en_GB-alan-low.onnx` | en | a low British man |
| `hfc_male` | `en_US-hfc_male-medium.onnx` | en | a worn male voice |
| `hfc_female` | `en_US-hfc_female-medium.onnx` | en | a worn female voice |
| `davefx` | `es_ES-davefx-medium.onnx` | es | una voz masculina grave (ES default) |
| `ald` | `es_MX-ald-medium.onnx` | es | una voz masculina seca |

**5. Frontend:**

```bash
cd frontend
npm install
npm run build        # produces frontend/dist/, served by the backend
```

**6. Run.** By hand:

```bash
cd backend
set -a && source ../.env && set +a
venv/bin/uvicorn app.main:app --host 0.0.0.0 --port 7777
```

or as a service (recommended). The shipped unit
(`deploy/quantumancy.service`) hardcodes `/root/quantumancy` — edit the two
paths first if your checkout lives elsewhere. A production install should
also add the persistence drop-in (`Restart=always`,
`StartLimitIntervalSec=0`, `Wants=postgresql.service`):

```bash
sudo cp deploy/quantumancy.service /etc/systemd/system/
sudo systemctl enable --now quantumancy
```

Then visit `http://<host>:7777` — or your Cloudflare Tunnel hostname for the
secure context that mic, WebUSB, and motion/magnetometer all require.

**7. Ollama models** (on the Ollama box, one-time):

```bash
ollama pull granite4.1:3b        # fast tier: fragments, ambient whispers
ollama pull minicpm-v4.5:latest  # chat tier: direct contact, minting, manifest
```

Any Ollama tag works — override with `OLLAMA_FAST_MODEL` / `OLLAMA_CHAT_MODEL`.

## Configuration

All settings live in `backend/app/config.py`, read from the environment or
`.env`. Required: `DATABASE_URL`, `OLLAMA_BASE_URL`.

| Env var | Default | Purpose |
|---|---|---|
| `DATABASE_URL` | — (required) | asyncpg connection string |
| `OLLAMA_BASE_URL` | — (required) | Ollama REST endpoint |
| `PORT` | `7777` | HTTP listen port |
| `OLLAMA_FAST_MODEL` | `granite4.1:3b` | fast tier |
| `OLLAMA_CHAT_MODEL` | `minicpm-v4.5:latest` | chat tier (replies, minting, manifest) |
| `LLM_MAX_CONCURRENCY` | `2` | simultaneous Ollama calls |
| `LLM_MAX_QUEUE_DEPTH` | `8` | queued calls before themed rejection |
| `LLM_COOLDOWN_SECONDS` | `8.0` | min gap between ambient whispers |
| `PIPER_VOICES_DIR` | `voices` | voice models (relative to `backend/`) |
| `DATA_DIR` | `data` | generated audio, served at `/audio/` |

## The Séance Protocol

One WebSocket per contact session: `/ws/session`, authenticated by the
`qm_session` cookie (close code `4401` otherwise). JSON frames both ways.

**Client → server:**

| Frame | Payload | Notes |
|---|---|---|
| `ping` | — | `pong` |
| `set_mode` | `mode: wire\|evp\|radio\|ouija\|emf` | persisted on the session |
| `language` | `en\|es` | switches LLM language + Piper voice |
| `summon` | optional `entropy` (conditioned room noise), optional `longitude` | rate-limited 4/min/user; the sky + entropy shape who answers |
| `anomaly` | `source`, `frequency`, `magnitude` | auto-summons at ≥3; then fragments (30/min/user) |
| `question` | `text` ≤500 | streamed reply (6/min/user) |
| `passive` | `enabled` | ambient Wire Ghost loop |
| `ritual_start` / `ritual_step` | `step` | 4 steps complete an attempt (6/min/user) |
| `judgment` | `verdict: trust\|banish\|test\|cross_over` | 10/min/user |

**Server → client** (single sender task; frames never interleave):

| Frame | Meaning |
|---|---|
| `session`, `pong`, `mode`, `passive` | plumbing |
| `status` | `attuning\|summoning\|gathering`; summoning carries `entropy_bits`, `sky` (moon/thinness), `geomagnetic` |
| `entity` | matched or minted (public fields only — hidden traits never leave the server unearned) |
| `anomaly_ack` / `anomaly` | counts; server-detected events |
| `utterance` | `kind: greeting\|fragment\|ambient\|reply\|manifest` — manifest is unprompted speech |
| `audio` | TTS + effects finished for an utterance |
| `reply_start/token/end` | streamed Direct Contact |
| `telemetry` | live Wire Ghost vitals |
| `tell` | a trait-shaped whisper for the Ghost Log |
| `ritual_complete` | `success`, `revealed` traits on success |
| `judgment_result` | `correct`, deltas, `at_peace`, `consequence` |
| `item_drop` | a relic falls |
| `error` | `rate_limited` / `veil_crowded`, themed |

**REST** (session-cookie auth where noted):

| Endpoint | Auth | Purpose |
|---|---|---|
| `POST /auth/register` · `login` · `logout` · `GET /auth/me` | — | argon2 + `qm_session` cookie |
| `POST /auth/guest` | public, 5/hr/IP | mint a `wanderer-` account |
| `GET /api/codex[?rarity,sort,limit]` · `GET /api/codex/{id}` | public | the shared registry / full dossier |
| `GET /api/stats` | public | live veil counters |
| `GET /api/conditions[?lon]` | public | moon, veil thinness, geomagnetic |
| `GET /api/seances/recent` | auth | the Ghost Log: last 12 sessions + echoes |
| `GET/POST /api/device` · `POST /api/device/telemetry` · WS `/ws/device-feed` | auth / device token | ESP32 pairing + live readings |
| `GET /api/inventory/{unlocks,items,sigils}` · `POST /api/inventory/unlocks/{key}` · `POST /api/inventory/sigils` | auth | the Reliquary |
| `POST /api/shop/waitlist` | public, 5/hr/IP | hardware waitlist |
| `GET /healthz` | — | `{"status": "ok"}` |

## Testing

**Backend** — pytest, **328 tests**. Requires `quantumancy_test` (dropped
and recreated every run — never run two suites concurrently against it; the
autouse drop/create fixture will fight itself):

```bash
cd backend && source venv/bin/activate
DATABASE_URL=postgresql+asyncpg://quantumancy:quantumancy@localhost:5432/quantumancy_test \
OLLAMA_BASE_URL=http://10.30.20.107:11434 \
python -m pytest -q
```

**Frontend** — Vitest + Testing Library, **366 tests**, plus a hard i18n
en/es parity gate (`npm run pretest`):

```bash
cd frontend && npm test
```

**Hardware-in-the-loop** (cannot be unit tested): the RTL-SDR sweep, mic
permissions, phone sensors, and everything in `firmware/` need real
hardware passes. `docs/CHANNELS.md` tracks exactly what has and hasn't had
one.

## Current State & Known Gaps

Honestly, in order of confidence:

- **Solid, verified live.** Auth (incl. guests), the Codex, Wire Ghost,
  EVP + spectrum scope + sonification, TTS + archetype voices, entropy,
  astronomy (validated against published ephemerides), the NOAA feed
  (verified against the live endpoint), rituals/judgment/essence, the
  Ghost Log, conditions, PWA manifest, phone layouts, the haunting layer.
  328 + 366 tests pass.
- **Should work, unverified on hardware.** `lib/sdr.ts` (WebUSB RTL-SDR) is
  written from librtlsdr register docs and has never met a real dongle;
  every entry point is time-boxed and fails soft. The magnetometer EMF
  path needs an Android device pass. All of `firmware/` compiles-by-eye:
  reviewed twice, never flashed.
- **Built but not yet reachable.** `lib/bluetooth.ts` (BLE presence field)
  has no séance panel yet.
- **Known drift.** The landing page's marketing grid still shows four modes
  (`MODE_ORDER` in `LandingPage.tsx`) — EMF and everything since aren't in
  the showcase.
- **Cosmetic.** One ~930 KB JS chunk; code-splitting would help first paint.
- **Intentionally unfinished.** The Ultimate Quantum Box is a waitlist —
  no hardware ships, no payment is taken, and the page says so.

## The Veil's Honesty Policy

- All LLM system prompts frame the entity as **a horror-fiction persona in
  an interactive art installation** — never a genuine paranormal claim.
- Every number shown to a seeker is a real measurement. The fiction
  interprets; it never fabricates. (`docs/CHANNELS.md` is the ledger.)
- Wire Ghost telemetry reads counters and timings only; packet payloads are
  never inspected. Only a longitude is ever kept from a location grant.
- Client entropy is untrusted by construction — it can add unpredictability
  to a draw, never steer one.
- If the Ollama box is dark, every channel degrades to procedural fallbacks
  — a summoning never visibly fails.
