Overview

Ghost Signal is a public-record + entropy-science project hosted entirely on Cloudflare Workers. It exposes a single GQ EMF-390 sensor (wired into Home Assistant) through a free, rate-limited, edge-cached API; a Claude-powered AI chat; a Twilio voice hotline at (601) 666-6602; a transmissions archive of every call; and a multimedia dossier of unexplained life events.

The project ships three pillars:

Pillar	What it is	Why it exists
Public sensor	GQ EMF-390 streaming EMF / EF / RF readings via Home Assistant → Worker → Cache	Anyone can poll, graph, audit, or build on real environmental EM data
Entropy AI	True random numbers harvested from a living electromagnetic field	Entropy no algorithm can fake — fit for CS, physics, and AI experiments
Public record	Multimedia dossier + AI hotline + transmission archive	Disclosure on the operator's terms — facts that would surface anyway

Ghost Signal is intended for:

1. Researchers who want a free, rate-limited, OpenAPI-documented public EMF feed
2. Cryptographers and ML engineers who need entropy that no algorithm can fake
3. Journalists and skeptics who want the raw, unfiltered record of an unusual life
4. Anyone with a story who wants their own pattern of phenomena added to the file
5. Builders who appreciate a working reference for Workers + Hono + D1 + KV + Twilio + Claude

Why This Exists

The operator (Brian Zalewski, B.S. Aerospace Engineering / Applied Sciences, Rutgers '11) has spent more than a decade as a senior software architect and another decade documenting an unrelenting pattern of phenomena: orbs, cellular SSIDs renamed to taunt research subjects, time-traveler-grade coincidences, possessions, exorcisms, EMF spikes that map to events, and a hotline of voicemails that should not exist. Rather than keep the file private, the file ships as a website, a public API, and a phone number.

Every reading, transcript, and entropy byte is permanent public record. If something is happening, the data is part of the case file. If nothing is happening, that's a case file too.

Quick Start

No keys. No accounts. Sixty requests per minute per IP.

Cache Strategy

Endpoint	TTL	Why
/api/v1/current	2 s	Real-time enough for charts; cheap on misses
/api/v1/sensors	2 s	Fan-out across families needs to stay fresh
/api/v1/history	15 s	Bucketed series tolerates short staleness
/api/v1/entropy	15 s	Recomputed against latest 15s of readings
/api/v1/random	0 s	Never cache — defeats true-randomness
/api/v1/timeline	300 s	Curated content, rarely changes

Bindings

Binding	Type	Purpose
ASSETS	Cloudflare Assets	Static public/ directory
EMF_DB	D1	Snapshot history, transcripts, newsletter, debate logs
RATE_LIMIT_KV	KV	Per-IP sliding-window counters + entropy seed
AI	Workers AI	Claude Haiku fallback for chat persona

Local Development

# Install
pnpm install

# Configure
cp .dev.vars.example .dev.vars

# Type-check + start dev server (auto-reload on save)
pnpm check
pnpm dev

The dev server runs at http://127.0.0.1:8787/. The Worker reads from a local mock unless EMF_SENSOR_HASS_URL and EMF_SENSOR_HASS_TOKEN are set in .dev.vars.

Environment Variables

Variable	Description	Default
EMF_SENSOR_HASS_URL	Home Assistant base URL	unset (mock mode)
EMF_SENSOR_HASS_TOKEN	Home Assistant long-lived access token	unset
EMF_SENSOR_ENTITY_ID	EMF magnitude entity in Home Assistant	sensor.gq_emf390_emf_mg

PUBLIC_API_RATE_LIMIT_PER_MINUTE	Per-IP request budget	60
ANTHROPIC_API_KEY	Claude key for chat / hotline	unset (uses Workers AI fallback)
TWILIO_AUTH_TOKEN	Twilio webhook signature secret	unset
RESEND_API_KEY	Newsletter sender	unset

Testing

# Full Playwright E2E suite (multi-feature flows, 6 breakpoints)
pnpm test:e2e

# Headed run
pnpm test:e2e:headed

# Open last HTML report
pnpm test:e2e:report

Local E2E uses a committed mock env at .dev.vars.playwright, runs the Worker in deterministic mock-sensor mode, enables dev-only __test/seed + __test/reset helpers, and writes state to .wrangler/state/e2e. Tests are stateful and accumulate — never deleted, only appended.

Suite	Coverage	Breakpoints
journey.spec.ts	Full homepage walkthrough — click, type, scroll, chat	375, 390, 768, 1024, 1280, 1920
api.spec.ts	Every documented endpoint + error envelope shape	n/a
hotline.spec.ts	TwiML round-trip via mock Twilio webhook	n/a
entropy.spec.ts	Distribution sanity checks on /random	n/a

Deploying

# Deploy to production (custom domain ghost.megabyte.space)
pnpm deploy

# Roll back the last deployment
pnpm wrangler rollback

# Tail live production logs
pnpm wrangler tail --env production --format=json

Cache purge after content changes:

curl -X POST \
  "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/purge_cache" \
  -H "X-Auth-Email: $CF_EMAIL" \
  -H "X-Auth-Key: $CF_KEY" \
  -H "Content-Type: application/json" \
  --data '{"purge_everything":true}'

See DEPLOY.md for the full runbook, secrets handling, and rollback playbook.

The Hotline

Call (601) 666-6602 from any phone. The call is answered by an AI persona running on Claude Haiku, recorded, transcribed, and published as a permanent transmission at /transmissions. By calling, you consent to all of that.

Step	What happens
1	Twilio answers and POSTs to /api/v1/twilio/voice
2	Worker streams a TwiML <Gather input="speech">
3	Caller's audio is transcribed by Twilio
4	Transcript is sent to Claude Haiku for the response
5	TwiML <Say> plays the AI reply, then re-gathers
6	On hangup, /api/v1/twilio/status finalizes the record + writes D1 + sends notification

The Dossier

Every section on the homepage is part of a public file. The dossier currently covers:

• The first 280 mG alarm at a Rutgers nanostructures lab
• "Radiation TDR" / "Radiation TDS" cellular SSIDs broadcast by nearby cell towers
• Celestial hallucinations — orbs, parted clouds, the Atlanta layover
• The 666 rock at the lake
• Father Mark and the rejected exorcism
• St. John's Soup Kitchen — reality editing in real time
• Jungle Habitat — the dead battery in the haunted safari
• The Volume Hack and the middle-finger cursor
• Time-traveler encounters and the high-order angel saying, "Tell your story"
• The Hobbits — a monthly gathering of geniuses with 4 GONDOR plates
• Funny Books — suspected MIB dispersal location

If you have your own pattern of phenomena, the hotline takes calls.

Contributing

Contributions, issues, and feature requests are welcome. Open an issue first if the change is non-trivial. The project follows the Emdash OS v6.0 workflow — TDD, real-user E2E, deploy-then-purge, no console errors, no shortcuts. Stale docs are bugs. PRs that fix doc rot are loved.

Sponsorship

Dear Awesome Person,

I create open source projects out of love. Although I have a job, shelter, and as much fast food as I can handle, it would still be pretty cool to be appreciated by the community for something I have spent a lot of time and money on. Please consider sponsoring me. Who knows? Maybe I'll be able to quit my job and publish open source full time.

Sincerely,

Brian Zalewski
