# AGENTS.md — Triad

**Three data layers for a personal knowledge system. Now extending toward v2 (four layers).**

## Identity

The triad is the **streamlines phase** of a WaterStorage-mapped personal knowledge system. With v2 feedback received, it's becoming a **four-layer system**: local / cloud / cookieblob / **liminal** (transpiration).

## Layers (current v0.2 → v2 beta)

| Layer | Path | Phase state | Physics |
|---|---|---|---|
| **Local** | `Triad/local/` | lake / reservoir | yours-only, instant |
| **Cloud** | `zo.pub/tenchi/triad` | evaporation | public, version-stable |
| **Cookieblob** | `Triad/local/triad-room-waterstorage.html` (and others) | soil surface | client-side, per-visitor |
| **Liminal** *(v2)* | conversation/scratchpad | transpiration | non-persistent by default; commits to local or cloud by choice |

## Streamlines (v0.2 + v2 additions)

- **Local → Cloud:** `seeds/triad-push.py` (diff + manifest)
- **Cloud → Cookieblob:** static HTML hydration
- **Cookieblob → Local:** JSON export + import
- **Liminal → Local:** "save this" (commit with timestamp)
- **Liminal → Cloud:** "share this" (push + sync)
- **Local → Liminal:** "bring [file] in" (working memory)
- **Cloud → Liminal:** "pull [coll] in" (synthesis)

## Rain (v2 + visitor flow)

Visitors arriving at a cookieblob room add **rain**. Rain is quarantined in **delta streams** until passing through the **Infiltration Filter** (see `infiltration-filter-spec.md`) before touching local bedrock.

## Lethe (the decay manifest)

- Cookieblob state decays if not exported.
- Local has a `.triad-decay.json` manifest: entries >30 days old marked for optional deletion. Deletion is manual but visible.
- Cloud never deletes; can be *deprecated* with a note.
- Liminal doesn't persist unless explicitly saved.
