The operational memory of the built environment

Published papers, open reference schemas, and notes from deployment. Everything here is citable and free to reuse.

The thesis

Three position papers, deposited on Zenodo under CC-BY and indexed in the European open-science graph. Each stands alone; together they make the case from three angles.

the diagnosis
The Verification Gap
Why the operational record of the built environment cannot, as it stands, be trusted — and why the standard remedies make it worse by attaching consequence to the record rather than to the work.
DOI 10.5281/zenodo.21470076
the stakes
Physical Ground Truth for Agentic AI
Why an irreducible core of physical ground truth remains human even after perception is solved — a witnessed judgment, recorded so an agent can verify it without trusting or surveilling the person who made it.
DOI 10.5281/zenodo.21470256
the category
The Digital Membrane
The infrastructure named: a governed surface where the world's knowledge flows inward and a place's witnessed record is written outward, the two kept distinct by a published constitution.
DOI 10.5281/zenodo.21470464

Governance and schemas

The constitution is public domain. The schemas are open so that others can build interoperably, or hold this one to account.

CC0 · public domain
The Concordat
Twelve articles, ten unamendable prohibitions, three data tiers, and a read-only gate. What is captured, and what is structurally forbidden.
DOI 10.5281/zenodo.21201731
reference schema
Operational Record Model
The append-only, hash-chained witness event: node and record structure, field sets by node kind, and the data tiers that govern retention.
DOI 10.5281/zenodo.21485677
reference schema
Digital Product Passport
A GS1 Digital Link–addressed passport for a physical craft good, carrying an append-only chain of custody recorded by role, never by named person.
DOI 10.5281/zenodo.21485623

From the deployment

Shorter notes, written from what actually happened. Every one points back to the papers.

Written by hand
How fifteen years of running restaurants led to Symbious — the card reader, the QR rails, and the thousand judgments no system was ever there to hold.
More notes will follow from the Song Wat pilot. If you would like them when they appear, write to ping@symbious.io.
