# DocForge

DocForge is a project-scoped documentation graph for people and AI agents. It validates canonical
documentation, builds a disposable search and relationship index, compiles bounded context, renders
declared manuals, visualizes project structure, and manages reviewable documentation changesets.

## What it does

- Validates stable Markdown/TOML nodes and typed relationships.
- Builds a deterministic SQLite search and graph index.
- Exposes project-bound CLI and MCP query surfaces.
- Creates, validates, diffs, and previews isolated changesets.
- Applies one explicitly approved changeset hash through CLI or gated MCP.
- Supports opt-in incremental adapters with reverse-dependency invalidation and full-build
  equivalence checks.
- Keeps function-scoped control-flow projections separate from the primary architecture graph.
- Runs a managed loopback graph browser with neighborhood, semantic Flow, convergence Web,
  function-scoped Logic, source inspection, and branch-aware node hiding.
- Supports generic documentation projects and project-owned source adapters.

DocForge never treats indexed text as instructions. It does not run shell commands, mutate Git,
build applications, deploy, publish, or select projects globally.

## Release 1

DocForge 1.0.0 is the first stable product release. It combines the project-scoped graph, CLI and
MCP query surfaces, reviewable hash-approved changesets, generic and project-owned adapters,
declared rendering, and the complete Nodes/Flow/Web visualization model in one supported release.

The post-1.0 incremental compiler is a backward-compatible, optional enhancement. Existing Release
1 adapters that implement only `load_projection()` continue to use the original complete-projection
path without modification. Adapters gain incremental performance only when they additionally
implement the source manifest and extraction methods. Incremental adapters must retain
`load_projection()` as their clean-rebuild fallback and equivalence oracle.

## Graph views

The browser presents the primary architecture graph through three complementary views and loads a
fourth function-scoped view only when requested:

- **Nodes** shows a bounded, relation-neutral neighborhood around the focus. It is the broad
  inspection view for seeing stored incoming and outgoing relationships without changing their
  direction. Semantic cards distinguish structure, behavior, dependencies, execution, data,
  evidence, context, and other relationships.
- **Flow** shows semantic origin-to-destination paths that terminate at the focus. DocForge
  reverses prerequisite-style relationships for presentation, so imports, dependencies, reads,
  inheritance, definitions, and tests flow toward the thing they help create or exercise.
- **Web** shows the larger convergence picture: Flow contributors plus contextual relationships,
  callers, containers, and direct members or execution dependencies owned by the focus.
- **Logic** shows the possible static control paths inside a focused Python, JavaScript, or C++
  function or method. Entry, decisions, actions, loops, convergence points, returns, and
  exceptions connect through explicit
  `TRUE`, `FALSE`, `NEXT`, `CASE`, `LOOP`, `RETURN`, and `RAISE` paths. Logic is stored separately
  and does not add statement-level noise to Nodes, Flow, Web, or search.

Graph cards show the node's readable leaf name and kind without clipping either value. The full
qualified identity remains available in the tooltip, compact descriptor, and full inspector.
The left browser panel can combine text, family, node-kind, language, and capability filters.
Quick presets expose Logic-ready nodes, Python callables, tests, routes, and documentation without
requiring users to know stable IDs. Selecting a canvas node emphasizes its directly connected
neighbors and edges while muting unrelated paths.

**Hide node** removes noise without changing the index. In Flow and Web, hiding a contributor also
removes upstream ancestors that no longer have a path to the focus. Nodes between the hidden
contributor and the focus stay visible, and alternate ancestor paths remain intact. In Logic,
hiding a step inserts an explicit omitted-path bridge so downstream control flow remains readable.
**Restore hidden** restores the presentation.

## Five-minute start

Requirements are Python 3.12+, `uv`, and Node.js/npm.

```bash
git clone forgejo@repo.andraxion.net:administrator/DocForge.git /absolute/path/DocForge
cd /absolute/path/DocForge
uv sync --group dev
npm ci

PROJECT=/absolute/path/MyProject
.venv/bin/docforge --project-root "$PROJECT" validate
.venv/bin/docforge --project-root "$PROJECT" reindex
.venv/bin/docforge --project-root "$PROJECT" visualize
```

Install the persistent per-user graph viewer once:

```bash
.venv/bin/docforge-viewer-manager install-user-service
```

Start an MCP server for one project:

```bash
.venv/bin/docforge-mcp \
  --project-root "$PROJECT" \
  --proposal-writer project-editor
```

Add `--canonical-applier project-editor` only when that MCP integration should expose the
hash-bound `docforge_apply_changeset` tool.
