# Glossary

> Terms used across this hub, in plain language.

## Hub

A user's public URL on mdfy. Lives at `mdfy.app/hub/{slug}`. Contains: a concept index, all the user's bundles, optional curated content. The hub is the unit that AI tools paste in as their persistent context source.

## Bundle

A topical grouping of documents. Has its own URL (`mdfy.app/b/{id}`). Carries pre-computed analysis (themes, insights, connections, document summaries, reading order). The bundle is the unit for per-project context — drop a bundle URL in AGENTS.md or .cursor/rules and the AI loads everything in the bundle.

## Doc

A single markdown document. Lives at `mdfy.app/d/{id}`. The atomic unit. Everything else is built out of docs.

## Concept index

The auto-derived list of every distinct concept the AI extracted from your hub's documents. Each concept links to the docs it appears in. Updated by the capture pipeline.

## Concept relations

Edges between concepts. "Hub-shaped memory" is_a "Memory architecture"; "Cross-AI portability" requires "Markdown URLs". The relations are what makes the index a graph instead of a list.

## graph_data

The JSON blob attached to each bundle. Contains nodes, edges, themes, insights, document summaries, reading order, key takeaways, gaps. Generated by an LLM analysis pass. Inlined in the bundle's URL response so any AI fetching the URL inherits the analysis without a second call.

## Capture

The act of moving content from somewhere else (a chat, a file, a webpage) into mdfy. Multiple capture surfaces: Chrome extension, MCP tools, paste-anywhere, file import.

## Recall

The query side of the hub. `POST /api/hub/{slug}/recall` runs a hybrid (BM25 + vector) retrieval, optionally reranks with Anthropic Haiku, returns the top-k matching chunks.

## Deploy

The act of *using* an mdfy URL as context. "Deploy this hub" = "paste the hub URL into your AI tool of choice." There's no actual deployment in the infra sense — the URL is just a URL.

## Edit token

A token that grants write access to a specific doc or bundle. Generated on creation. Can be regenerated. Not an OAuth session — just a string that the API checks.

## Owner

The user_id that owns a doc or bundle. Authenticated via Supabase Auth. Owner ≠ edit-token-holder; either path grants write.

## Restricted

A permission state where a doc is non-public AND has at least one entry in `allowed_emails`. Only owners + listed emails can view.

## Private

A permission state where a doc has `is_draft = true`. Only the owner can view. (The legacy name "Draft" was changed to "Private" in v6 because "Draft" read as "incomplete," which wasn't the intent.)

## Concepts in this document
- **graph_data** _(entity)_
  JSON blob containing LLM-generated analysis (themes, insights, connections, summaries) attached to bundles for zero-latency AI retrieval.
- **Concept index** _(concept)_
  The map layer that shows which concepts appear across documents, enabling strategic fetching before committing to prose.
- **Bundle** _(concept)_
  mdfy's payload format containing canvas analysis, themes, insights, and concept relations for a project.
- **Capture** _(concept)_
  The ingestion mechanism that moves content from external sources into mdfy across multiple surfaces.
- **Edit token** _(concept)_
  API credential granting write access to a specific doc or bundle independent of OAuth authentication.
- **Hub** _(entity)_
  The foundational public unit in mdfy—a user's persistent context source combining concept index, bundles, and curated content.
- **Doc** _(entity)_
  The atomic unit in mdfy—a single markdown document that forms the building block for all larger structures.
- **Permissions model** _(concept)_
  Access control system distinguishing between owners, edit-token holders, restricted email lists, and private/draft states.
- **Concept relations** _(concept)_
  Edges between concepts that transform the index from a flat list into a queryable graph structure.
- **Recall** _(concept)_
  Query-side retrieval using hybrid search (BM25 + vector) with optional reranking to return relevant chunks from a hub.
- **Deploy** _(concept)_
  The practice of embedding an mdfy URL as context in AI tools to grant them access to a hub's knowledge.
