First M2 vertical slice: CanonLog -> HTTP -> /dm/narrate -> prose ->
screen -> fact-harvest, with a §13 degraded-DM fallback on any failure.
Pure DmService core behind an injectable DmTransport seam (headless-
testable); throwaway harness scene; one authored fallback line under
client/content (renderer owns the file's home).

The client half of the canon log contract: typed RefCounted model with
invariants-in-the-model, Luck-centric game state, new-game construction
from origin+world+creation, turn-to-turn mutators, and a pure regex tag
extractor. Headless GUT-tested logic layer; UI/HTTP/save-load deferred.

Design spec for the §11 canon log, plus origin seeds as thin initial-state
overlays over a single static world. Three layers (world content / origin seed /
runtime canon log), the in/out boundary (numeric Luck never enters the AI
payload, §7), field-level schemas, new-game construction order, turn-to-turn
maintenance, and JSON storage validated on both client and api.
Folds content/npcs and content/quests under content/world/; adds
content/world/{locations,items} and content/origins. fallback/ kept outside
world/ (authored prose, not id-referenced).
