The Field Guide — Privacy

The trust-graph work behind the Hitchhikers Field Guide — a walking AR client that needed real one-hop trust, met by the ToIP DTG trust-graph work, which had it and had never been near a street. Built 2026-08-13 → 16 on the field farm (privacy.fieldguide), served to the team from the embassy Pis, and merged here 2026-08-17 as the federation's thirteenth site.

What this is

A counter-spec built as evidence rather than argued as prose: eight suites, 124 properties, every ruling anchored to a test that fails if the ruling is broken.

Start at Field Guide Trust Overlay — it indexes everything else.

The rulings

• The Meet Rite — how an edge is made, in a street, between two phones
• Audience Is Granted Not Computed — why two hops is nothing, not half
• The Pairwise Peer Reference — the leak that nearly undid all of it
• A Wiki Fork Is Not An Audience — publication is not a rung on the ladder
• Erosion Is A Rate Not A Cliff — a meet from four years ago is not a meet from Tuesday
• Shared Quest Is Not Consent — where the reply disagrees with something already shipped
• The Rejection Register — every way the model says no
• Rounding Is Not A Detail — two correct implementations, one pin, opposite sides of the street

Answering the pack directly

• The Question Map — all twenty questions in the ARWorld documents, each anchored to a property that runs
• Phase 0 Acceptance — the five acceptance criteria, executable
• The Overlay Ranking — the score-terms table, made mechanical
• The ARWorld Pack — the source documents themselves
• OASIS And The Cred Spec · The DTG Credentials Core Specification · The DTG ZKP Task Force · Could This Be Zero Knowledge — the lab side of the reflection

The record

I will show you where I stood.
I will not tell the world I stood anywhere.

Nine of them in Proverbs Of The Trust Overlay, each with the property that would fail if it were broken.

The two days, with the runtime traces beside them: 2026-08-15 The Predicate Walks To Islington · 2026-08-16 The Checklist Answers Back.

Run it yourself

The assets lane carries the workbench — the model, both sides' documents, the conformance vectors, and a captured run report. The Working Files indexes it. Node and Python standard libraries only; nothing to install, nothing to log into.

Lineage

~/field_guide_privacymage is the working directory — the build source of this wiki lane, not a repo. The durable research substance is folded into the corpus: the counter-spec, both checked maps, the notes and the runtimes live at agentprivacy-docs/research/fieldguide/; the lab-side filing is exploration X11 in the DTG workbench; the chronicle, the tome act and the graph weave sit in their own repos. Sister copies of this wiki serve the team from the embassy Pis over the tailnet (mitch.private.fish · fieldguide.pi4.private.fish), pushed as FedWiki forks naming their source, so every copy's journal says where it came from.
