docs(content): create the content roadmap — Spine, BOM, Backlog

Implements the docs restructure half of the content-track design (the
currency item is code and stays unbuilt). Content stops being unbounded:
the work is now a countable checklist with an end.

content/roadmap.md — new. Three sections, only one of which is ever the
work:
  Spine     Greywater Docks + one dungeon, patron Ghaul the Yoke; the
            cosmology touching ground. Plus what is already canon.
  BOM       ~57 discrete pieces for a complete, playable game, per
            milestone. Numbers, not vibes.
  Backlog   Everything the slice does not need. Not a debt — where ideas
            go to be safe.

Its rule: never author anything that is not in the Bill of Materials.

The BOM carries a Fixed/Variable column — the seven-campaign saga spec's
only ask of this table. ~37 fixed / ~20 variable: a second town costs the
20, not the 57. That is also the exact split v2 generation would need.

content/lore/canon-roadmap.md becomes a pointer (older specs and plans
reference the old path). An items-and-prices table does not belong under
lore/.

docs/roadmap.md — M4..M9 each gain a "Content it consumes →" line into
the BOM.

world-building skill — SKILL.md and evals.json now point at
content/roadmap.md, and the skill is told to respect the BOM rule: ideas
that arrive during authoring go to the Backlog, not into the world.

Build + --check green; generated content/world and content/server are
byte-identical. No Python touched.

@@ -66,24 +66,30 @@ Each screen is recreated as a Godot 4.7 Control-node scene against the mockups (
 - ○ **Title screen** — new game / continue / load / settings; the entry point. Author it editor-first (ADR 0001). **⛨ saga:** a fourth entry path (*begin the next campaign of an existing saga*) lands later — don't build it, just don't hardcode the flow as `new game → creation → world` so it can't be added. *§2: n/a · depends on the Theme · goal: first impression, into the world.*
 
 ### M4 — Character creation
+*Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): calling blurbs + the Bloodsworn's patron choice (fixed); origins (variable). **~4 pieces.***
 - ○ **Character creation UI** — the mock's screen over our proven model: race + calling cards, six stats with **LCK hidden entirely** (§7), 3d6 floors, the **+3 additive-only spend-up** pool (§8, matches the `character-creation-stats` model), live origin blurb + nameplate. **Reconcile class names** here (§8 vs the mock's callings). Feeds new-game canon-log construction (already built). **⛨ saga:** `NewGame.construct` takes `creation` as a plain `Dictionary` — keep it that way. The creation *scene* produces that dict but must not become the only thing that can (a saga synthesizes it and skips the UI). Emit `race_id` + `calling_id` into it. *§2: state · depends on the creation model (M0) + Theme · goal: build a character.*
 
 ### M5 — Tactical combat (gridless)
+*Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): abilities for the 3 POC classes (fixed); 1 enemy family (4 units) + boss, **tier 1** (variable per tier). **~15 pieces.***
 - ○ **Combat turn manager + HUD** — the Combat HUD `Component` state machine as GDScript: initiative order, the action economy (Action/Bonus/Move), ability resolution, click-to-target, victory/defeat; tokens on the iso board as **flavor only, no movement grid** (§10). Seeded per encounter (§10). **Reconcile damage determinism** here (§7/§10 vs the mock's ranges). Combat flavor is async optional Narrator calls (reuses M1). **⛨ saga — the level curve is no longer open:** design it to a **ceiling of L20 across 7 tiers** (tier N ≈ levels 3N−2 … 3N; exact bands tunable, the ceiling is not). **Enemy stat blocks carry `tier: 1..7`; there is no scaling multiplier, and there never will be** — a tier-6 world has *different monsters* (proximity to a king is the power scale), not a rat with 40× HP. Class abilities are planned to L20. The M5 content BOM (1 enemy family + boss) is **tier 1**. *§2: state (flavor text a thin AI layer) · depends on the pipeline for flavor · goal: real stakes.*
 
 ### M6 — Dialogue screen
+*Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): 6 NPCs — persona + `knowledge[]` + gated topics (§6), variable. **~6 pieces.***
 - ○ **Dialogue UI + reshaped Adjudicator** — wrap the *proven* NPC free-text loop (`/npc/speak`, M2) in the mock's conversation screen: NPC portrait, live disposition meter, the NPC's spoken line + DM narration beat, and the **hybrid** input (choice chips with skill/approach tags **plus** the free-text line, §15). The **Adjudicator** (`/dm/adjudicate`, strict JSON §12, one-retry) lands here as the interpreter for the free-text "describe your own action" escape hatch — most turns use buttons. *§2: both (text = NPC voice · state = validated moves/actions) · depends on the NPC role (M2) · goal: conversation inside the game's UI.*
 
 ### M7 — Inventory & character sheet
+*Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): 6 weapons, 4 armour, 3 consumables, **1 cursed item** (+STR / −LCK — §7 says day-one). All fixed. **~14 pieces.** Prerequisite: the build tool gains `item` + `quest` namespaces (and `tier: 1..7`).*
 - ○ **Inventory & equipment** — the paper-doll (12 slots) + Satchel grid, category tabs, item detail, encumbrance, derived stats; item seed-data from the mock's `items()` map as `Resource`s. *§2: state · depends on the Theme + item model · goal: gear the player manages.*
 - ○ **Character sheet** — attributes (modifier-forward, LCK still hidden), saving throws, the "in a fight" derived grid, skills, talents, afflictions/conditions, the DM's-notes bio. *§2: state (display) · depends on the stat model · goal: the character, legible.*
 
 ### M8 — World systems
+*Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): the **price table in copper** (fixed); 3 map locations + the road, shop stock, the quest chain (variable). **~8 pieces.** The **currency change lands before M7** — store everything in copper, format at the display edge; it has a client consumer (the shell's purse).*
 - ○ **World-map travel** — region map, location markers (settlement/dungeon/fog), roads + planned route, danger ratings, travel time, set-out. *§2: state · depends on the shell · goal: move between places.*
 - ○ **Shop economy** — buy/sell with a fence: purses, stock/owned, the ~40%-sell loop, gritty disabled-CTA reasons, merchant reaction lines. *§2: state (merchant reaction = a thin authored/AI layer) · depends on inventory · goal: an economy loop.*
 - ○ **Quest log** — active/completed/failed tabs, objectives checklists, rewards, tracked quest; reads the canon log's `active_quests` (§11). *§2: state · depends on the quest model · goal: track the story.*
 
 ### M9 — Framing, AI-flavor & persistence
+*Content it consumes → [BOM](../content/roadmap.md#2-bill-of-materials): authored fallback per AI surface (§13); shrine + Luck-drift events; humiliation seeds. All fixed. **~10 pieces.***
 - ○ **Save / load + pause / settings** — the pause overlay + data-driven settings; save/load over the canon log + game state (seeds preserved, §10). **⛨ saga — the save is two objects, not one:** a durable **`Saga`** (sheet, level, companions + approval, humiliations, deeds, `kings_slain`, `campaigns_completed`, signature item) and a per-campaign **`Campaign`** (`CanonLog` + `GameState` + world + seed). **Humiliations move to the `Saga`** and are *projected* into the canon log — today they live in the log and would die with the campaign. This is the §10 seed argument applied to persistence: cheap now, a rewrite once saves exist in the wild. *§2: state · depends on the systems existing · goal: persistence + framing.*
 - ○ **Luck fully wired** — generation exists (Plan B); this adds **drift events** (real bed, shrine blessing, killing something praying), **one shrine**, **one cursed item** (+STR / −LCK). Visible only in prose (§7). Gates the Improviser. *§2: state · depends on the item + event systems · goal: the signature system, live.*
 - ○ **Improviser** — `/dm/improvise`: minor off-script events, **§7-sandboxed by construction** — a validator that only applies whitelisted state changes (dignity, never progress; structurally incapable of ending a quest). Fires on Luck; hooks Cadwyn. *§2: both · depends on Luck being wired · goal: bad luck as a story, not a fine.*
