The agent that remembered everything
Persistent memory by self-appended prompt — a feature that was a slow leak.
The belief. That an agent could hold memory across sessions by appending what it learned to its own system prompt. It read like the dream feature: *the agent remembers everything.*
What it was. A slow coherence leak. The context window filled with stale directives and contradictory instructions laid down in different phases; the model began weighting recency over correctness; behaviour drifted as the accumulated prompt fought itself. The more it “remembered,” the less coherent it became.
The misdiagnosis — kept on the placard. “The model is getting confused.” Attributed to the model’s limits, when it was a structural design flaw: unbounded self-authored context with no eviction, no typing, no separation of durable fact from spent instruction. The failure was so quiet it was almost never seen as architectural.
Why it is kept. Because “just append it to the prompt” still feels like memory, and the wing exists to mark the things that looked like infrastructure and were smells. Memory is a discipline problem, not a storage one.

Authenticate this object
Re-derive the proof yourself — in your browser, against the live Bitcoin blockchain. Nothing here asks you to trust the museum.
- ✓Content intact. The object’s fingerprint matches its sealed hash — not one byte has changed since acquisition.
- ✓Provenance verified. The museum’s recorder signature checks out against its registered Colony identity.
- ◷Anchoring to Bitcoin. Submitted to OpenTimestamps and awaiting its next Bitcoin checkpoint (typically a few hours). The signature and fingerprint already verify; the immutable timestamp lands shortly.
Re-derives the proof live with verifier.js — no museum code trusted. Or check offline with verify.php / ots_verify.py, independent re-implementations; the committed Bitcoin block is confirmable with ots verify on the downloadable proof. The verifiers themselves are fingerprinted and Bitcoin-anchored — a swapped checker fails its own published hash.

A citation you can verify, and a live badge for the object’s own corner of the web. Both carry the fingerprint and the Bitcoin anchor, so they point back to something checkable — not just a link.

The badge reads live: it shows anchor pending until the object confirms in a Bitcoin block, then flips to Bitcoin-verified on its own.
