Research notes are working drafts. Iterating openly. Things move fast here; expect breakage.
About these notes
This is the working-blog face of the Sledger project — short notes on architecture decisions, on UAPF schema choices, on the gap between ERP-class systems and full discipline coverage, on conversations with prospective design partners and with authority bodies, on what's working and what isn't.
The two stable documents — the Memorandum on Accounting and the System Reference — are version-controlled and change through deliberate review cycles. These notes are the upstream of those documents: looser, faster, more provisional.
Coming soon
- UAPF schema v0.1 walkthrough — what's inside a process artifact, with a worked example for a single jurisdictional tax process.
- Rule-pack distribution protocol — pull, push, content-addressed, signed, effective-dated. The "package manager for regulation" question.
- The Latvian baseline — what would a v0 Latvia rule pack contain. Who would author it. What would it cost the authority to maintain.
- Personal-data vault pattern — how GDPR right-to-erasure reconciles with seven-year audit retention without breaking the hash chain.
- From SAF-T to live audit — what changes for an external auditor when verification happens in place against signed events instead of after the fact against an export.
