Development updates and engineering decisions

An AI agent without long-term memory is a stateless function call — powerful in isolation, useless for continuity. When I started building DPO2U's six-agent ecosystem, every agent had the same problem: it couldn't remember what happened yesterday. LEANN changed that, but getting there meant debugging chunk sizes, fixing duplicate indexes, and learning why 256-token chunks turn a 2-hour build into a 16-hour one.
The question I get most often is not "how does zero-knowledge compliance work?" It's "who pays for the AI inference?" The answer is: the agents pay for themselves. Here's how a one-person startup sustains six autonomous agents without external funding, venture capital, or manually topping up API credits.
When I chose Docusaurus 3 for DPO2U's documentation site, the decision wasn't obvious. Here's why I picked it over Nextra, GitBook, and Mintlify — and the configuration decisions that shaped the final result.
The the host chain bboard example stores the owner public key hash on the public ledger. Anyone with an indexer can track who owns which post. We set out to hide it — and learned that Compact's privacy model is more nuanced than a single keyword.
This post documents the implementation of ownership hiding with selective disclosure, including a compiler-enforced lesson about what sealed actually means in Compact 0.21.
