# schema.yaml — single source of truth for artifact frontmatter.

# PROJEKTERWEITERUNGEN gegenüber neckbeard v0.3.1 (Original:
# docs/sources/upstream/neckbeard-v0.3.1/schema.yaml; Design:
# docs/design/done/2026-08-11-neckbeard-migration.md, ADR-0012/0013):
#   * issue: Pflichtfelder milestone (M1–M6) + priority; Status-Enum um
#     next/waiting erweitert; due/host/area/wartegrund/gitlab_iid;
#     Regel waiting_requires_reason; globale Regel wip_limit (max. 2
#     in-progress) in validate.py.
#   * issue.projekt (ADR-0019): Herkunfts-Projekt adoptierter
#     Komponenten-Issues; zusammen mit gitlab_iid die Spiegel-Adresse.
#     Fehlt das Feld, ist management gemeint.
#   * component: neuer Typ unter docs/components/ (Dateiname = Slug).
#   * wiki-page: Area-Enum um "vision" erweitert; Status-Enum um
#     "declined" erweitert (Rahmenwerk geprueft, deckt nicht ab — das
#     Muster bleibt bestehen). Begruendung steht am Feld selbst.
#     ⚠️ status/harvested_in fehlten nach dem v0.3.1-Merge ganz und sind
#     hier nachgetragen; HERKUNFT.md kann das nicht mitfuehren, weil sie
#     unter docs/sources/ gesperrt ist, waehrend ADR-0024 ihre Tabelle
#     fuer massgeblich erklaert. Widerspruch, als Befund notiert.
#   * project_section_marker auf unsere Marke gesetzt; ledger und
#     verdict unverändert von upstream übernommen (v0.3.1).

scope:
  # Files considered artifacts. Templates and raw sources are exempt.

  # Files whose inline links are checked, but which need no frontmatter
  # (root-level prose: README, AGENTS, WORKFLOW, generated STATUS, ...).
  link_only:
    - "*.md"

# Files an adopting project holds byte-identical against its vendored
# baseline (AGENTS.md §5). They are copied into repositories that do not
# have this repo's docs/, so they must carry no repo-relative link — a
# link that resolves here and nowhere else makes the adoption path
# unfollowable. Mention an ADR by its identifier instead.
vendored:
  - "AGENTS.md"
  - "WORKFLOW.md"
  - "CLAUDE.md"

# An adopting project appends its own always-on rules below a marker in a
# vendored file (AGENTS.md §5). Everything from the marker on belongs to
# that project, is never copied anywhere, and may link freely — the rule
# above applies only to the upstream part. Adopters set their own marker.

# http://, https:// or mailto: are treated as external and only
# format-checked; everything else must be a repo-root-relative path
