"""The canon/ethos centralisation bundle (goal 27, review refinement):
the WEB becomes the single owner of the canonical texts and the ethos —
served over the per-saddle-token API the daemon already speaks, carried
inline on every assignment, and surfaced to the advisor through the
same three tools the daemon's ToolLoop exposes. The scenarios:

- GET /api/saddle/canon lists the library (15 texts, headers parsed:
  slug/title/author/source/licence/summary plus words and bytes)
- GET /api/saddle/canon/{slug} returns one full document; an unknown
  slug answers 404
- every canon/ethos route requires the bearer token (401 without)
- GET /api/saddle/ethos serves the one web-side ethos text
- a fresh assignment payload (the fake saddle's next-task ask) carries
  the same text as its `ethos` member
- the advisor's tool set declares list/read/query_canonical_text, its
  system prompt carries the ethos section verbatim, a scripted turn
  lists then reads a canon text, and query_canonical_text's side call
  hits the same scripted endpoint
