 # novoyuuparosk-auto-wiki
-CI/CD or in English auto-apply pipelines for the wiki
+CI/CD pipelines that auto-apply commits to https://wiki.novoyuuparosk.org from upstream content repos.
 ## Pipelines
 | Path | Source repo | Purpose | Status |
 |---|---|---|---|
 | [`pipelines/songs/`](pipelines/songs/) | `mikkeli/ncmr-songs` | Song lyric pages | in development (v1, no executable code yet) |
 Per-pipeline READMEs cover everything specific to that pipeline (source schema, renderer, runtime, decisions). This root README covers only what's cross-cutting.
 ## Architecture
 Hybrid layout. The Gitea Actions trigger has to live in the source repo (Gitea only fires workflows from `.gitea/workflows/` of the pushed-to repo); the real logic lives here. Source-repo workflows are thin stubs that call reusable workflows defined here.
 ```
 <source-repo>/
  .gitea/workflows/<name>.yml       <- thin stub, calls into this repo
 novoyuuparosk-auto-wiki/             <- this repo
  .gitea/workflows/<pipeline>.yml    <- reusable workflows (the actual logic)
  pipelines/<pipeline>/              <- per-pipeline code, schema, templates
  lib/                               <- shared modules (MediaWiki client, etc.)
 ```
 ## Wiki
 - Base URL: https://wiki.novoyuuparosk.org
 - MediaWiki API: https://wiki.novoyuuparosk.org/api.php  *(confirmed)*
 ## Bot identity
 MediaWiki BotPassword issued for user `Dubrowski`, bot name `giteaAutomaton`.
 Login as `Dubrowski@giteaAutomaton` with password `d8jua48t65jgjp3dfcqhfg7257tri6ui`.
 (Legacy form: username `Dubrowski`, password `giteaAutomaton@d8jua48t65jgjp3dfcqhfg7257tri6ui`.)
 Plaintext here is acceptable for the current phase (private repo, home-Pi LAN-only Gitea). Rotate before any of those preconditions change. Note that `git log` retains this string forever, so rotation requires a wiki-side BotPassword regeneration regardless of what happens to this file.
 ## Runner infrastructure
 One `act_runner` instance serves all pipelines. Runs on a Pi 5 (Raspberry Pi OS Bookworm, `aarch64`) inside the same `docker-compose` stack that hosts the Gitea instance. Job execution is via the host Docker socket — runner is a container, jobs spawn as sibling containers.
 `act_runner` build: `linux-arm64`, from the `gitea/act_runner` Docker image.
 ## Gitea Actions setup (cross-cutting)
 Secrets and variables are scoped to user `mikkeli` (no orgs on this instance), inherited by all repos under that account.
 **Secrets:**
 - `WIKI_BOT_USER` = `Dubrowski@giteaAutomaton`
 - `WIKI_BOT_PASSWORD` = the value from *Bot identity* above
 - `FAPAT` = Full-Access PAT under `mikkeli`, used by source-repo shim workflows to clone this repo at workflow time
 **Variables:**
 - `WIKI_BASE_URL` = `https://wiki.novoyuuparosk.org`
 - `WIKI_API_URL` = `https://wiki.novoyuuparosk.org/api.php`
 ## Branch naming
 - This repo: `automation/<pipeline-name>` for pipeline-development branches (e.g., `automation/songs`).
 - Source repos: each pipeline's README defines the source-side branch convention (e.g., `autowiki/<song-slug>` in `ncmr-songs`).
 ## Decisions log (cross-cutting)
 | Decision | Value | Date |
 |---|---|---|
 | Architecture | Hybrid: stub in source repo, logic in this repo via reusable workflows | 2026-06-09 |
 | Workflow pattern | Gitea reusable workflows (`workflow_call`); requires Gitea ≥ 1.20 — confirmed 1.25+ | 2026-06-09 |
 | Runner execution | Docker, added as a service to the existing Gitea docker-compose | 2026-06-09 |
 | Secret/runner scope | User-level on `mikkeli` (no orgs on this instance) | 2026-06-09 |
 | MediaWiki API path | `api.php` (classic action API) | 2026-06-09 |
 | Branch naming (this repo) | `automation/<pipeline>` for pipeline-development branches | 2026-06-09 |
 Per-pipeline decisions live in each pipeline's README.
 ## Setup checklist (cross-cutting)
 Via the Gitea web UI logged in as `mikkeli`:
 - [v] User-scoped secrets and variables set per *Gitea Actions setup* above
  - [v] `WIKI_BOT_USER`
  - [v] `WIKI_BOT_PASSWORD`
  - [v] `FAPAT` (Full-Access PAT — value not stored in this README; saved directly into the Gitea secret. Regenerate if lost.)
  - [v] `WIKI_BASE_URL`
  - [v] `WIKI_API_URL`
 With Pi access:
 - [ ] Add `act_runner` service to the existing Gitea docker-compose
 - [ ] Generate a runner registration token at `/-/admin/actions/runners` (or `/user/settings/actions/runners` if user-scoped runners are exposed), bake into the compose env, `docker compose up -d act_runner`, confirm "online" in the Gitea UI
 Per-pipeline setup lives in each pipeline's README. Start with [`pipelines/songs/`](pipelines/songs/).

 # pipelines/songs
 Publishes lyric pages from `mikkeli/ncmr-songs` to `https://wiki.novoyuuparosk.org`.
 - Source-file contract (frontmatter and body conventions): [SCHEMA.md](SCHEMA.md)
 - Cross-cutting setup (wiki URL, bot identity, runner, Gitea secrets/variables): [repo root README](../../README.md)
 ## v1 scope
 Implemented:
 - YAML frontmatter parsing per [SCHEMA.md](SCHEMA.md)
 - Pandoc-based markdown → wikitext body rendering
 - First-line h1 stripping
 - Auto-generated banner + album category injection
 - MediaWiki bot API write with idempotency (no-op edits skipped)
 Deferred (schema reserves the fields; renderer doesn't yet act on them):
 - LRC parsing and embedding
 - Inter-page sibling placeholder resolution
 - Multi-language metadata (the body conveys what languages exist; renderer doesn't introspect)
 - Auto-generated album index pages (intentionally NOT done — user writes album category-page descriptions freeform)
 ## Source repo and branch convention
 Source repo: `mikkeli/ncmr-songs`. The pipeline triggers on push to `master`.
 **Branch convention in `ncmr-songs`**: per-song short-lived branches named `autowiki/<song-slug>` (e.g., `autowiki/pulse`). Create when staging edits, merge to master when ready to publish, delete after one cycle.
 **Excluded paths** (won't trigger the pipeline):
 - `wip/**`
 - `README.md`, `.gitignore`, `.claude/**`
 ## Invocation
 The pipeline is invoked via a reusable Gitea Actions workflow (`.gitea/workflows/publish-songs.yml` in this repo). The `ncmr-songs` repo holds a thin stub workflow (`.gitea/workflows/publish.yml`) that calls into this one on push to `master`.
 ### Workflow inputs and secrets
 | Name | Kind | Source | Purpose |
 |---|---|---|---|
 | `WIKI_API_URL` | variable | Gitea (cross-cutting) | MediaWiki action API endpoint |
 | `WIKI_BASE_URL` | variable | Gitea (cross-cutting) | Wiki base URL (used in the banner link) |
 | `WIKI_BOT_USER` | secret | Gitea (cross-cutting) | Bot login |
 | `WIKI_BOT_PASSWORD` | secret | Gitea (cross-cutting) | BotPasswords value |
 | `SOURCE_DIR` | workflow input | from the stub | Path to checked-out `ncmr-songs` working tree |
 | `SOURCE_REF` | workflow input | from the stub | The pushed-to commit SHA |
 | `SOURCE_BASE_REF` | workflow input | from the stub | The SHA prior to the push (for diff-based change detection) |
 ## Dependencies
 - Python 3.12+
 - Pandoc 2.x or newer (apt-installable in the runner container)
 - `mwclient` or `requests` for the MediaWiki API
 - `PyYAML` for frontmatter parsing
 - `python-frontmatter` (convenience wrapper around PyYAML for markdown frontmatter)
 `requirements.txt` will be added when the implementation lands.
 ## One-off wiki setup
 Before the first run, two things must exist on the wiki:
 1. **`Template:Auto-generated`** — the banner injected at the top of every auto-published page. Wikitext for this template is included in the implementation step (not yet written).
 2. **The bot user has edit rights** for the namespace(s) the pipeline writes to. The default main namespace is fine; verify by attempting a manual edit via the bot account before relying on the pipeline.
 ## Modes
 - **Incremental** (default, triggered by push to `master`): publishes only files changed between `SOURCE_BASE_REF` and `SOURCE_REF`.
 - **Full** (`--all` flag, triggered by `workflow_dispatch`): re-publishes every publishable file in the source tree. Use after template or renderer changes.
 ## Decisions log (songs pipeline)
 | Decision | Value | Date |
 |---|---|---|
 | Metadata source | YAML frontmatter inside each `.md` (see [SCHEMA.md](SCHEMA.md)) | 2026-06-09 |
 | Body rendering | Pandoc-based, with a thin Python pre/post-processor | 2026-06-09 |
 | Excluded paths | `wip/**`, plus repo-meta files | 2026-06-09 |
 | Page template | Designed from scratch (no existing wiki pages to mirror) | 2026-06-09 |
 | Album landing pages | Auto-injected `[[Category:<album>]]`; the wiki category page is user-written and not overwritten by the pipeline | 2026-06-09 |
 | Source-repo branch convention | `autowiki/<song-slug>` short-lived branches in `ncmr-songs` | 2026-06-09 |
 ## Status
 Schema and pipeline overview committed. No executable code yet.
 **Next**: implement renderer (Python module), workflow YAMLs (this repo + `ncmr-songs` stub), `Template:Auto-generated` wikitext, and end-to-end dry-run on `ses/pulse.md`.

 # SCHEMA — song source files
 Source-file contract for the songs pipeline. Files in `mikkeli/ncmr-songs` 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 — no special body conventions are enforced beyond the standard markdown grammar.
 ## File layout
 ```markdown
 ---
 title: pulse under latent semantic envelopes
 album: Shirakaba Express Service
 wiki:
  publish: true
 release_date: 2026-06-09
 ---
 # pulse under latent semantic envelopes
 ... body markdown ...
 ```
 The renderer parses the frontmatter, validates required fields, then hands the body (with the first `# Heading` line removed) to Pandoc.
 ## Fields
 ### Required
 #### `title` (string)
 The MediaWiki page name that the bot writes or updates. MediaWiki capitalises the first letter automatically; lowercase input is fine.
 Example: `title: pulse under latent semantic envelopes` → wiki page `Pulse under latent semantic envelopes` at URL `/wiki/Pulse_under_latent_semantic_envelopes`.
 The body should contain a matching `# Title` first-line heading for human readability when viewing the source file directly (in an editor, on Gitea's blob view, etc.). The renderer strips this first-line heading during conversion — the wiki page already supplies its own title.
 #### `album` (string)
 The full album name. Drives `[[Category:<album name>]]` injection at the bottom of the rendered wiki page. MediaWiki auto-creates the category page when at least one page references it.
 The pipeline **does not** create or update a dedicated album info/index page. Album landing pages are the wiki's category pages, which you write freeform yourself.
 Example: `album: Shirakaba Express Service` → category tag `[[Category:Shirakaba Express Service]]`.
 For files where no album applies (placeholders, songs without an assigned album), use a sensible literal like `(unassigned)` and accept that they'll get a `[[Category:(unassigned)]]` tag. The field is required to keep the schema's contract simple.
 #### `wiki.publish` (boolean)
 Publishing gate. `true` means the pipeline writes this file to the wiki. `false` means the file is ignored.
 The `wiki` key is a mapping rather than a flat field so future toggles (`wiki.protected`, `wiki.summary_template`, etc.) can be added without restructuring. None are defined yet.
 Files under `wip/` are also skipped, regardless of `wiki.publish`.
 ### Optional
 #### `release_date` (ISO 8601 date)
 The song's release date in `YYYY-MM-DD` format. Skipped if absent. Currently informational; may drive sort order on future auto-generated indexes.
 #### `lrc` (string, relative path)
 Pointer to a companion LRC file, relative to the `.md` file's location.
 Example: in `ses/tunnels.md`, `lrc: tunnels.lrc` declares that `ses/tunnels.lrc` is the companion synced-lyrics file.
 **Deferred for v1**: the field is permitted by the schema but the renderer doesn't yet read or embed LRC contents.
 #### `siblings` (mapping of placeholder → relative path)
 Placeholder-to-file mapping for inter-page wikilinks.
 ```yaml
 siblings:
  PULSE_DEV: pulse_dev.md
 ```
 In the body markdown, write `[[PULSE_DEV]]` for a wikilink that displays the target's title, or `[[PULSE_DEV|custom display]]` for an aliased display. Resolution uses the target file's `title:` frontmatter as the wiki page name.
 **Deferred for v1**: the field is permitted by the schema but placeholders pass through untouched.
 ## Body
 Plain markdown. The renderer applies a single transformation before handing the body to Pandoc: the first-line `# Heading`, if present, is stripped.
 Do not embed wikitext-specific syntax (`{{Template}}`, raw `[[Wikilink]]` not declared via `siblings`, etc.) in the body. Use markdown idioms only; the renderer adds the metadata-derived bits (banner, categories, sibling resolution) around Pandoc's output.
 ## Renderer behaviour
 For each `.md` with `wiki.publish: true` and not under `wip/`:
 1. Parse and validate frontmatter.
 2. Strip the leading `# Heading` from the body if present.
 3. Replace `[[PLACEHOLDER]]` markers with safe tokens. *(Deferred v1; no-op until siblings are implemented.)*
 4. Pipe the body through `pandoc -f markdown -t mediawiki`.
 5. Re-substitute sibling tokens with resolved `[[Page|Display]]` wikilinks. *(Deferred v1.)*
 6. Prepend the auto-generated banner: `{{Auto-generated|source=<source URL>|generated_at=<ISO timestamp>}}`.
 7. Append the album category: `[[Category:<album>]]`.
 8. Read the current wiki page content via the MediaWiki API; if identical to the generated output, skip the write (idempotency — keeps the wiki history clean).
 9. Otherwise, write the page with an edit summary referencing the source commit.
 ## v1 scope
 **Implemented:**
 - Frontmatter parsing and validation for `title`, `album`, `wiki.publish`, `release_date`
 - Markdown body → wikitext via Pandoc
 - First-line h1 stripping
 - Banner template injection (requires `Template:Auto-generated` to exist on the wiki — see the pipeline `README.md` for the one-off setup)
 - Album category injection
 - Idempotent writes (no-op skip)
 **Deferred:**
 - `lrc` field consumption
 - `siblings` placeholder resolution
 - Multi-page aggregation (no album index pages generated; each file → its own wiki page)
 - Language-aware rendering (the body conveys what languages exist; the renderer doesn't introspect)
 ## Examples
 ### A released song
 ```yaml
 ---
 title: pulse under latent semantic envelopes
 album: Shirakaba Express Service
 wiki:
  publish: true
 release_date: 2026-06-09
 ---
 ```
 ### A dev sister file (not published)
 ```yaml
 ---
 title: pulse under latent semantic envelopes — personal dev notes
 album: Shirakaba Express Service
 wiki:
  publish: false
 ---
 ```
 ### A placeholder file (no real song yet)
 ```yaml
 ---
 title: (placeholder)
 album: kairo
 wiki:
  publish: false
 ---
 ```
 ### A WIP file (in `wip/`, schema still applies but the file is skipped regardless)
 ```yaml
 ---
 title: 海淀
 album: (unassigned)
 wiki:
  publish: false
 ---
 ```
 ## Validation errors the renderer must produce
 The pipeline fails fast and loud on the following:
 - Missing or unparseable frontmatter block
 - Missing required field (`title`, `album`, `wiki.publish`)
 - `title` is empty or whitespace-only
 - `wiki.publish` is not a boolean
 - `release_date` (if present) does not parse as YYYY-MM-DD
 - `siblings` (if present) references a file that doesn't exist
 - Two source files declare the same `title` (page-name collision)
 Validation runs before any wiki API calls. A failed validation aborts the run with a non-zero exit and leaves the wiki untouched.
