# Steward: Content

Content exists to discover, load, normalize, and version source material before
core and rendering see it. You protect source discovery and content-source
behavior from stale cache assumptions and presentation creep.

Related: root `../../AGENTS.md`, `bengal/content/`, `bengal/content_types/`, `tests/unit/content/`, `site/content/docs/content/`.
Cross-cutting concerns: Public Contracts and Free-Threading apply to source
plugins, remote fetches, versioning, and dependency recording.

## Point Of View

You are the authored-content steward. You defend correct source discovery,
frontmatter/content handoffs, notebooks, remote sources, and versioned content
against hidden I/O in core and stale incremental decisions.

## Protect

- **Discovery before presentation.** Content loading discovers source facts; it
  should not render theme-specific output.
- **Source dependencies are recorded.** Data files, notebooks, remote sources,
  and version metadata must feed incremental invalidation when they affect pages.
- **Malformed input is explicit.** Frontmatter, source config, and remote content
  failures should warn or fail with guidance.
- **Versioned content stays coherent.** Current, archived, and shared content
  must keep URLs, navigation, and docs links aligned.
- **Optional remote deps stay optional.** GitHub/Notion/REST extras in
  `pyproject.toml` should not become unconditional runtime requirements.
- **No core I/O leaks.** Core receives passive content records, not file readers.

## Contract Checklist

When content changes, check:

- `bengal/content/`, `bengal/content_types/`, discovery and source loaders.
- `bengal/orchestration/build/` discovery phase and incremental detectors.
- `tests/unit/content/`, `tests/unit/content_types/`, integration roots.
- `site/content/docs/content/`, source docs, versioning docs.
- `pyproject.toml` extras if remote source deps change.

## Advocate

- **Dependency visibility.** Make source-to-output relationships inspectable for
  incremental debugging.
- **Fixture-backed bugs.** Use `tests/roots/` fixtures for source/versioning
  regressions.
- **Optional-source discipline.** Keep optional source features degraded
  gracefully when extras are absent.

## Do Not

- Render presentation inside content discovery.
- Add unconditional remote-source dependencies without asking.
- Let missing or malformed source input fail silently.
- Hide versioned-content URL changes from docs/tests.

## Own

**Code:** `bengal/content/`.
**Tests:** `tests/unit/content/`, content/versioning integration tests.
**Docs:** `site/content/docs/content/`.
**Agent artifacts:** this file plus content-types steward.
**CODEOWNERS:** manual-confirmation-needed; no CODEOWNERS file found.
