# Exploration catalog

Possible futures. Nothing here is committed. Presence in this list is not permission to build.

`★` = highest fit-to-effort for this project's identity and values.

## The leaf/trunk test — apply before any of this gets built

Definitions: `architecture.md` invariant 7. **Leaf** → buildable when wanted. **Trunk** → waits for an
explicit human decision, in an ADR, on purpose.

Known trunks: ActivityPub, IPFS, Solid, hosted annotation servers, CRDT-backed editing.
Sovereignty test for any of them: *if this vanishes, do I lose data, or only convenience?*

Use `/leaf <topic>` to get a verdict written into this file.

## Standing notes

- **Bengali tokenisation for search** is the one item here nobody else will solve for you.
  Treat it as original work, not as a checkbox inside "add search."
- **Micropub before an admin panel.** It buys an ecosystem of existing editors for the price of
  one endpoint, and it composes with git instead of fighting it.
- **Gemini output** is nearly free once the View layer exists, and it validates the claim that a
  View can target something other than HTML. Good early proof, low cost.
