# Active slice
```text
Slice: DFG-4 deterministic previews and renderer orchestration
Goal: Produce bounded, reproducible previews and configured derived outputs from validated project data without granting arbitrary execution or canonical write authority.
In scope: Preview contracts, renderer declarations, input and output confinement, deterministic render identity, stale detection, atomic derived output replacement, render status, MCP preview and render-status tools, and tests.
Out of scope: Canonical changeset application, arbitrary commands, project-specific adapters, Git mutation, deployment, accounts, HTTP transport, and a web UI.
Done when: The same validated project and renderer version produce the same preview identity; stale or escaped inputs fail closed; failed renders preserve prior derived output; the MCP surface cannot select an undeclared renderer or command.
Owners: Canonical files retain facts. Changesets retain proposals. Preview and renderer owners produce disposable derived artifacts only.
Slice: DFG-5 Worldforge shadow adapter
Goal: Prove that a project-specific adapter can reproduce Worldforge documentation semantics and generated output without changing the live Worldforge workflow.
In scope: Worldforge source mapping, authority and graph validation, active and phase context profiles, render models, parallel index comparisons, and byte-for-byte shadow output checks.
Out of scope: Canonical changeset application, live workflow replacement, public output changes, deployment, arbitrary commands, Git mutation, accounts, HTTP transport, and a web UI.
Done when: The shadow adapter matches current Worldforge nodes, edges, bounded contexts, validation results, and rendered outputs while existing Worldforge manual tests remain green.
Owners: DocForge core retains generic mechanics. The Worldforge adapter owns Worldforge-specific semantics. Existing Worldforge sources and builders remain authoritative during shadow adoption.
Proof: Pending implementation and verification.
```

impersonate another writer. Create, update, move, and delete tools write only isolated JSON
changesets below the configured changeset root.
Projects may also declare render views with confined template, preview, and output paths. The first
built-in renderer converts CommonMark to escaped HTML through strict template tokens. MCP may render
validated changesets only into isolated preview paths. Declared project output is generated through
the explicit local CLI command and is never an MCP operation.

### Next gate
DFG-4: add deterministic previews and confined renderer orchestration without canonical application.
## DFG-4 deterministic previews and renderer orchestration
### Changed
- Added optional project-declared template, preview, view, and derived-output configuration with
strict root confinement, overlap rejection, stable view IDs, and configured size limits.
- Added an explicit renderer protocol backed by a closed built-in registry. Configuration cannot
name commands, modules, executable paths, or undeclared renderers.
- Added the `generic_html` renderer with pinned `markdown-it-py` CommonMark parsing, disabled raw
HTML, fixed safe template tokens, deterministic node ordering, navigation, metadata, content, and
relationship output.
- Added render identities covering canonical and proposal inputs, node and edge identities, view
configuration, template hash, renderer contract, and exact Markdown parser version.
- Added atomic per-view CLI rendering, non-writing render status, and isolated changeset previews.
Input changes detected before replacement preserve prior output.
- Added `docforge_preview_changeset` to MCP and made `docforge_render_status` report configured view
hashes and state. MCP cannot render declared project output or select a renderer or command.
- Split shared configuration validation, render configuration, renderer contract, and orchestration
into focused modules instead of expanding the project loader or MCP translation layer.
### Verification
- Renderer tests prove repeatable identities and bytes, current and stale status, isolated previews,
escaped raw HTML, CommonMark conversion, unchanged canonical and declared output, configured
limits, symbolic-link rejection, and preservation of prior output after invalid or changing input.
- Configuration tests reject command-like fields, unsupported renderer IDs, protected output paths,
undeclared views, oversized templates and output, and unsafe symbolic links.
- CLI tests cover declared render, render status, isolated preview, and structured unknown-view
failure. Protocol tests exercise preview through the official in-memory MCP transport and prove
declared output remains absent.
- Ruff formatting and lint checks, Python compilation, all five JSON schema parses, and the locked
dependency check passed.
- All 35 core, CLI, changeset, concurrency, renderer, in-memory MCP, and real stdio tests passed with
`ResourceWarning` treated as an error.
### Limits
- The first built-in renderer emits one self-contained HTML file per view. Multi-file asset bundles
and project-specific view models remain future adapter work.
- Preview generation validates proposals but does not apply them to canonical documentation.
- Declared project-output rendering is an explicit local CLI integration action, not an MCP tool.
- Worldforge and unrelated-project adapters remain unopened.
### Next gate
DFG-5: reproduce Worldforge semantics and generated output through a shadow-only adapter without
changing the live workflow.

Normal MCP access does not expose canonical application, arbitrary file writes, previews, renderer
execution, shell commands, Git mutation, build commands, deployment, or publication.
## Declared rendering and previews
Render configuration is optional. A configured project declares one template root, one isolated
preview root, and one or more stable view IDs. Each view names a built-in renderer, template,
derived output file, title, and optional family filter. Paths are resolved under the project root
and may not overlap canonical content, authority files, changesets, templates, or previews.
The initial `generic_html` renderer uses pinned CommonMark parsing with raw HTML disabled. Templates
are UTF-8 files with a fixed token vocabulary; they cannot name commands, modules, or executable
renderers. Render identity covers the canonical source hash, optional changeset hash, selected node
and edge identities, view configuration, template hash, renderer contract, and exact parser version.
An explicit CLI render atomically replaces one declared derived output. MCP can render a validated
changeset only to its isolated preview path. Status recomputes expected output without writing and
reports `current`, `stale`, `missing`, `unsafe`, or `oversized`. Input changes detected before atomic
replacement fail without replacing the prior output.
Normal MCP access does not expose canonical application, declared project-output rendering,
arbitrary renderer execution, arbitrary file writes, shell commands, Git mutation, build commands,
