# SCHEMA — SES light novel source files

Source-file contract for the SES pipeline. Files in `novoyuuparosk-wiki/ses-light-novel` must follow this contract to be picked up by the auto-publisher.

The schema lives entirely in the YAML frontmatter block at the top of each `.md` file. The body below the frontmatter is plain markdown, rendered to MediaWiki wikitext by Pandoc.

## File layout

```markdown
---
title: Wakkanai
type: story
wiki:
  publish: true
---

## Section 1
### The coast or the shore

... body markdown ...
```

The renderer parses the frontmatter, validates required fields, then hands the body to Pandoc. The first-line `# Heading` is preserved — use it if you want an h1 on the rendered page.

## Fields

### Required

#### `title` (string)

The MediaWiki page name, without the `SES:` prefix — the pipeline prepends it automatically. MediaWiki capitalises the first letter; lowercase input is fine.

Example: `title: Wakkanai` → wiki page `SES:Wakkanai` at URL `/wiki/SES:Wakkanai`.

#### `wiki.publish` (boolean)

Publishing gate. `true` means the pipeline writes this file to the wiki. `false` means the file is ignored.

`wiki` must be a YAML mapping, not a list:

```yaml
# correct
wiki:
  publish: true

# wrong — will be silently skipped
wiki:
  - publish: true
```

### Optional

#### `type` (string)

The page type. Drives `[[Category:SES:<type>]]` injection. If omitted, the pipeline falls back to the file's immediate parent directory name (`stories`, `people`, `places`, etc.).

Example: `type: story` → `[[Category:SES:story]]`.

If neither `type` nor a meaningful directory name is available (file sits at the repo root), the fallback is `uncategorized`.

#### `categories` (list of strings)

Additional wiki categories to inject beyond the automatic `SES` and `SES:<type>` ones. Each entry becomes `[[Category:<value>]]`.

```yaml
categories:
  - Featured
```

## Body

Plain markdown. The body is passed through Pandoc as-is — the first-line `# Heading` is not stripped, so you can use h1 elements freely. Do not embed raw wikitext (`{{Template}}`, raw `[[Wikilinks]]`, etc.) unless you intend the literal output.

## Renderer behaviour

For each `.md` with `wiki.publish: true`:

1. Parse and validate frontmatter.
2. Pipe the body through `pandoc -f markdown -t mediawiki`.
4. Prepend the auto-generated banner: `{{Auto-generated|source=<source URL>|commit=<sha>}}`.
5. Append category tags: `[[Category:SES]]`, `[[Category:SES:<type>]]`, and any entries from `categories`.
6. Read the current wiki page content via the MediaWiki API; if identical to the generated output, skip the write (idempotency).
7. If the page exists and does not start with `{{Auto-generated`, skip with a warning (manual page protection).
8. Otherwise, write the page with an edit summary referencing the source commit.

## Implemented scope

- Frontmatter parsing and validation
- `SES:` title prefix
- Pandoc-based markdown → wikitext body rendering (h1 elements preserved)
- Banner template injection
- `Category:SES` + `Category:SES:<type>` injection (type from frontmatter, fallback to parent directory)
- Additional categories via `categories` list
- Idempotent writes (no-op skip when content matches)
- Manual-page protection (skip pages without auto-gen banner)
- Files without `wiki.publish: true` silently skipped

## Not in scope (intentional)

- Sibling/cross-page link resolution — write wikilinks directly in the body
- Separate upload of companion files (no LRC equivalent)

## Examples

### A story chapter

```yaml
---
title: Wakkanai
type: story
wiki:
  publish: true
---
```

Wiki page: `SES:Wakkanai`. Categories: `SES`, `SES:story`.

### A world entry (type from directory)

```yaml
---
title: Emms White
wiki:
  publish: true
---
```

File at `world/people/emms_white.md`. Type falls back to `people`.
Wiki page: `SES:Emms White`. Categories: `SES`, `SES:people`.

### A draft (not published)

```yaml
---
title: Helsinki
type: place
wiki:
  publish: false
---
```

## Validation errors the renderer must produce

Files without `wiki.publish: true` are silently skipped. The pipeline fails fast only on opted-in files with invalid data:

- Missing or empty `title` on a file with `wiki.publish: true`
- `wiki.publish` present but not a boolean
- `categories` (if present) is not a list
- Two publishable source files resolve to the same wiki title
