sovereign tool · in one pipeline.
Paste a question. Watch five-angle research run. Watch claims get refuted by a three-vote adversarial panel. Watch a sovereign HTML get built from the confirmed evidence, verified against the spec, shipped to Pages, and signed into an audit chain — end-to-end.
Output · FallSection21 v1.0
A sovereign single-file tool · 11 features built · 11/11 verified · ~5KB · MIT.
A factory that researches itself.
The factory of factories was the prototype. The substrate is the destination. fall-substrate doesn't just generate a tool from a spec — it generates the spec FROM research, then verifies the result against the original research, then ships it. End-to-end, sovereign, cited.
Plausibility ≠ truth.
In our deep-research test 52% of LLM-generated claims were refuted. Adversarial verification is a first-class primitive here, not an afterthought.
Sovereignty ≠ regression.
Single-file tools that run on the user's device beat cloud platforms when the data is sensitive, the cost is constant, and the surface is auditable.
Specs from research, not vibes.
A tool spec generated from 23 cited sources outperforms a spec dreamt up by a single LLM in one pass. Every feature traces to its evidence.
Audit ≠ trust.
Every output traceable to inputs. Every claim sourced. Every transformation Ed25519-signed across prevHash → docHash → configVersion.
Seven primitives. One mesh.
Each product stands alone. Together they compose. fall-substrate is the flagship — but every sibling product is a callable primitive of the same SDK. Read the architecture doctrine.

Your key. Your data. Your audit chain.
Everything below is stored in your browser's IndexedDB only · never sent to a server · never leaves the device. To wipe it, clear site data in your browser.
Anthropic API key (BYO)
Key is stored in IndexedDB fall-substrate / settings store. Never sent to any server. The live demo above does not consume your key — it plays a scripted pipeline.
GitHub push (optional)
In sovereign mode, push is performed by the gh CLI on your machine — paste no token. In pro mode, the substrate uses this token to create the repo and enable Pages for you.
