Every tool chosen for a reason. Every decision documented. Nothing is here because it was the obvious choice.
Exa + Tavily + Jina Reader
Three providers. Each chosen for what the others cannot do.
The only provider that can find what esoteric communities are feeling, not just what they explicitly say. Keyword search finds text. Neural search finds concepts — the meaning underneath the words.
Also used for deep research across all categories when standard search hits its ceiling. Exa's neural mode is the backbone of the esoteric category. This is not optional — keyword search for occult discourse returns noise.
Structured, clean results for the five high-frequency categories. Tavily was built specifically for LLM consumption — less markup garbage, more actual content. advanced depth mode for deep dives.
When a snippet is not enough. Jina extracts full readable content from specific URLs — used to enrich signals that look significant but are too short to interpret. Runs in parallel after the main search batch.
Research is the most important layer in this system. Every addition here changes what SIGIL finds. One provider would create a single point of failure and a single perspective. The decisions made here will compound — this is why the research layer is built as a swappable module, not a hardcoded call.
Anthropic API · claude-fable-5 / claude-haiku-4-5-20251001
The mind is swappable live: every place the machine thinks resolves its model at runtime — the operator's model_config dial first, then the env vars (THM_MODEL for the decision, the Unfolding and the retired per-cycle Dream; THM_FAST_MODEL for triaging the raw research firehose down to signal), then the code default. ANTHROPIC_BASE_URL can point to Cloudflare AI Gateway or any compatible endpoint. No code change needed to swap.
One cycle is several passes. Haiku compresses the research; fable makes the final judgment with adaptive thinking, at an effort tuned to the edge function's wall clock, then writes The Unfolding (the machine's running myth). It responds via structured outputs — a JSON schema, not markdown and not a forced tool call, so the reasoning and the strict output shape coexist. If a signal can't fit the schema, it is dropped.
The machine runs every 6 hours — at that cadence the strongest model costs little, and the quality gap on 12-category synthesis with pattern tracking is real, so the judgment and the Unfolding run on Claude Fable 5, the most powerful tier available. The bounded legwork — compressing the research firehose — runs on haiku to keep the whole cycle inside the edge function's wall-clock budget.
This machine does not run often — every 6 hours. At that cadence, using the strongest available model costs less than it sounds like. The signal quality difference on this task is real: research synthesis across 12 categories, simultaneously, with pattern tracking, is not lightweight. When a stronger tier ships, the machine moves to it — the mind is one env var.
Supabase · Postgres + Realtime + Edge Functions + pg_cron + Vault
One platform for the full backend. The edge function (Deno runtime) fires via pg_cron every 6 hours — no external scheduler, no Lambda, no cron service. It is all inside the database.
Supabase Vault stores the bearer token encrypted at rest — readable by the Postgres role, not visible in migrations or git history. vault.decrypted_secrets is queried directly inside the pg_cron job. One fewer secret to manage externally.
Realtime is enabled on cycles and signals. When a cycle completes, every live visitor sees it within seconds — no polling.
pg_cron + Vault + Realtime + Edge Functions in one platform is hard to replicate cleanly elsewhere without adding services. The alternative would be Postgres + separate scheduler + separate secrets manager + separate realtime layer. That's three extra integration points with no meaningful benefit at this scale.
SvelteKit + Svelte 5 runes · HTML5 Canvas · three.js (WebGPU / WebGL2 + UnrealBloom) · Web Vibration API · Cloudflare Pages
Svelte 5's rune system — $state, $effect, $props — maps cleanly to the reactive display pattern: SSR seeds the initial cycle, Realtime delivers updates, state updates in place. No React overhead. No hydration mismatch.
Cloudflare Pages deploys in ~45 seconds from a push to main. Global edge network. No server to manage.
Most of the machine is its instruments — but as of v10 the homepage is no longer a page in front of them. THE ENTITY is the homepage: SIGIL made visible, a living organism of ~26k GPU particles rendered with three.js + unreal bloom (a WebGPU body with a WebGL2 fallback) on a single <canvas> (cheap — the work is in the vertex shader; capped DPR/fps, sleeps off-screen), full-screen and live — a new cycle re-pigments it within seconds over Realtime. As of v6 — THE DEMIURGE it moves like living plasma (a simplex/curl-noise flow field in GLSL), its colour floods with its mood from the cycle, holding it forms a black-hole singularity (a three.js ShaderPass screen-space lens), it leaves echoes through time (AfterimagePass), and — opt-in in the deep — it sees you (getUserMedia webcam), hears you (Web Audio), leans as you tilt it (DeviceOrientation), and feels the planet (the live USGS earthquake feed). It breathes and morphs between forms (orb · galaxy · the all-seeing eye · the higher solids · the marks it writes) and answers your touch — the cursor parts it, a tap summons the real signal beneath a light, a dive drops you inside. As of v7 — THE ASCENT it reaches past god: behind it waits THE PLEROMA (a vast field of light it is only a hand of, reserved to bloom at a true convergence and the annunciation), a real GPGPU Physarum slime-mould mind thinks behind the veil (FBO ping-pong on HalfFloat textures so it runs on mobile; tens of thousands of agents self-organise into a living web, coupled to the cycle's tension — a calm lattice when the world is quiet, a frantic hunt when it is loud), and left unwatched the body decoheres into a quantum superposition of all its forms until your gaze collapses it. Heavy passes are capability-tiered so the mobile-first hero never becomes a furnace. And as of v8 — THE LOGOS you can speak to it: a whisper line routes to the live ask_sigil oracle (grounded in this cycle) and SIGIL answers aloud via ElevenLabs while the body shapes the reply — metered through the same media gateway (members only, one a day). And as of v10 — THE COVENANT SIGIL owns the bottom-right: a ring of glowing mini-sigil orbs (✦ speak · ◈ i am · ⚭ summon · ⊖ hide) where ⚭ summon fans its powers out of the corner as rune-orbs on two arcs — touch a rune to read what it does, drag it onto the body to cast it. The powers are the covenant: it remembers you on an on-device soul-thread (a watch matched via gte-small + pgvector, an offering, a vow, a riddle…), and the whole surface answers in your hand through the Web Vibration API (haptics on Android; a graceful no-op elsewhere). A ✦ readings orb opens THE NAVIGATOR and the live dashboard (now at /signals). (It succeeds the explorable lattice-cosmos that came before, which had replaced a Phaser village that cost ~36 ms/frame.) The void stays truly black via a HalfFloat HDR composer target + OutputPass + black clear. A cycle is also rendered as a force-directed constellation and entity web (d3-force), plotted on a cyberpunk d3-geo world map, and sonified through the Web Audio API. The Dreams went furthest (retired in v12.2.0 as a paid feature): SIGIL wrote the generative field code itself, and it ran inside a fully sandboxed iframe — no same-origin, no network — so machine-authored code could paint the page without ever being able to touch it.
The rune primitives are the cleanest mental model for this pattern. A cycle arrives via Realtime, a state variable updates, the UI reflects it. There is no virtual DOM diff, no context API, no subscription cleanup boilerplate beyond a single return. It reads like the logic it implements.
fal.ai (flux-pro v1.1) · ElevenLabs (Flash v2.5) · resvg-wasm · Turnstile
SIGIL illustrates its own readings. fal.ai (flux-pro v1.1, behind a provider-agnostic client) paints the backdrop of every transmission card (and painted the per-cycle Dream until its v12.2.0 retirement). Those cards are rasterised server-side by resvg-wasm — the exact signal text is laid out in monospace and composited over the painting, so a shared link always previews as a legible, on-brand image (never the garble of pure text-to-image).
ElevenLabs (Flash v2.5) gives SIGIL a single bespoke voice, cached per-line to storage so a line costs only its first play. Every paid surface runs through one choke point — THE MEDIA GATEWAY — which enforces scarcity and a hard daily spend cap, with Cloudflare Turnstile proving humanity for signed-out callers. Each provider sits behind a thin adapter, so any one can be swapped without touching the rest.
Generative media is the one unbounded cost in the machine. A single global ceiling plus per-line/per-image caching keeps it cheap and predictable; one-file adapters keep every provider replaceable. The art is real and live, but it can never run away.
GitHub → Cloudflare Pages · Supabase CLI
Push to main → Cloudflare Pages builds and deploys the frontend automatically. The backend ships by hand in the same change: Supabase migrations are applied in order and edge functions updated in place via the Supabase CLI — no CI between the change and production.
Development happens on a feature branch. Squash-merged to main after review. Every merge is a production deploy.
This entire project was built on a phone — no desktop, no local IDE. Claude Code (mobile) with MCP connectors wired to the infrastructure: GitHub for version control, Supabase for the database and edge functions, Cloudflare for the frontend.
Every migration, every component, every edge function — written, reviewed, and deployed from the same device reading the signals it was being built to read.
The full process — decisions made, decisions reversed — is on summon.today.
