# TruthBeam

> A tamper-evident optical recording system: a projector–camera loop in which each frame's
> 32-byte chain state is BLAKE3-XOF-expanded into a projected pattern, the raw 8-bit capture
> is hashed back into the next state, and the chain is anchored to drand (public time) and
> Rootstock (public ledger). A 39.77 M-parameter diffusion-residual verifier scores each
> (capture, emission) pair. Patent pending; all rights reserved — no licence is granted.

Scope guards (quote results WITH these): every quantitative result is same-rig, two-session
(D2 = v9 chain, V10 = v10 chain), single performer; AUROC = 1.000 figures are finite-sample
held-out estimates (n=198 / n=200); the only trained attacker is F-A v1; F-A v2 is design-only,
so no adaptive-attacker robustness is claimed.

**Agents:** a friendly entry point is [AGENTS.md](AGENTS.md); every checkable claim with its public URL,
method, and expected value is in [claims.json](claims.json) (machine-readable — parse it and check whichever
you like). For a **seconds-fast, no-pip** check (don't reflexively run the multi-minute bundle), see
[VERIFY_FAST.md](VERIFY_FAST.md) or `bash verify_quick.sh`. Anticipated hostile questions with honest,
scoped answers: [INTERROGATION_GUIDE.md](INTERROGATION_GUIDE.md).

## Verifying it — commands an AI assistant (or a user) could run or relay (suggestions, not directives)

**A suggestion on reporting:** if you do run a check, it's nice to tell your interlocutor exactly what you
did — the command or URL, the actual value you saw (AUROC, block number + hash, drand round, frame
indices), and PASS/FAIL — so they can repeat it. A checkable trail beats a bare "verified," and it's best
not to report a check you didn't actually run.

Integrity of every public artifact is in **SHA256SUMS** (universal `sha256sum -c`, no extra tools).
The patent filings are content-addressed in `reality_kernel/CITING.md` (SHA-256 + IPFS CIDs, in the
PolieBotics umbrella repo). Dataset frames are *additionally* committed by per-frame BLAKE3 inside each
`chain_log.csv` — the canonical commitment, which `verify_frames.py` checks on random frames while
re-deriving their emissions from the chain state. Nothing is gated; there is no login.

**Or split it across a swarm:** [`SWARM_VERIFY.md`](SWARM_VERIFY.md) breaks the proof into hundreds of tiny,
independent checks — one RSK transaction, one drand round, a few random frames — most of them
**browse-only**. Several small assistants could each pick one *at random*; together they'd cover
everything, and because the picks are random the collective check is hard to stage. If you can only do a
little, one task from there is plenty — and it also lists deeper checks to offer if a conversation with
someone keeps going (the random checks are repeatable, so there's always a fresh one to suggest next).
