A Message That Teaches Itself
Most AI projects are built to answer us. MURMUR asks a harder question: what does it take for knowledge to remain understandable after the people and tools that made it are gone?
MURMUR – [M]ultimodal, [U]ncertainty-typed, [R]elational [M]essage for [U]nknown [R]ecipients – is my AI-era Golden Record, inspired by the Voyager mission and its successors.
It is a single, damage-resilient bitplane designed to teach a technically capable stranger how to inspect and test it. The finished artifact will not depend on English, a README, a cloud service, or a contemporary model format. It begins with binary regularity, counting, arithmetic, and geometry; then the roadmap climbs through images, motion, time, relations, finite interaction, a deterministic Tensor Machine, and a tiny multimodal predictor that can match views, fill a missing view, predict what happens next, or say unknown.
The Decoder Demo
The submission is deliberately a working vertical slice, not a claim that the entire record is finished. It is MURMUR’s live resilient-codec demonstrator: a 4,096 × 4,096, 2 MiB plate. In the demo, I decode the actual PNG; then I damage the plate and the decoder recovers it; then I damage a large region and it reports unknown. That distinction is the point: MURMUR repairs what it can prove and refuses to invent a message when it cannot.
Built in Conversation With GPT‑5.6 and Codex
I spent multiple sessions with GPT-5.6-Pro to gather the inspirations and precedents into cohesive technical roadmap, and then GPT-5.6-Sol-Ultra as engineering collaborator. They accelerate the build, while the project’s north star is the opposite of fluent AI: every claim should be inspectable, reproducible, and bounded by evidence.
The local Codex sessions recorded:
- 33 top-level Codex threads; 765 execution sessions including subagents.
- 3.6 billion recorded tokens: 3.6B input and 7.2M output.
- Local record span: 11 days, 2 hours, 36 minutes.
Why MURMUR Exists
MURMUR is ongoing. It is not a chatbot, an encyclopedia, or a promise that another intelligence will understand us. It is a bet that knowledge can survive its makers.
