docs(spec): divide FTH callings along the war (Bonesetter/Bloodsworn)

Adds the FTH-axis calling mapping to the cosmology spec: Bonesetter
channels the Warden, the Bloodsworn (names the [CANON-TBD] warlock
calling) pacts one of the Seven, Hedge-Mage is a pointed outsider,
martials unaligned. Luck-immunity intent kept as flavor and flagged for
the M5/Improviser reconcile (§7-sensitive), not built here.

-## 7. Acceptance criteria
+## 7. Callings & the war (the FTH axis)
+
+The settled races/classes spec (`2026-07-11-races-and-classes-design.md`) explicitly
+leaves calling **lore/flavor to "a separate canon/worldbuilding effort"** and marks two
+calling names `[CANON-TBD]` for the canon session. This pass resolves that seam **for the
+divine axis only** — the two FTH callings draw power from **opposite sides of the war**;
+every other calling stays **unaligned** (worship-for-everyone dilutes the divine
+specialness and pushes the world toward the epic register we deliberately avoided in §2).
+
+| Calling | Stat | War stance |
+|---|---|---|
+| **Bonesetter** (Cleric) | FTH | channels **the Warden** — divine casting *is* the good god's blessing, worked through a mortal |
+| **Bloodsworn** (Warlock, was `[CANON-TBD]` 🔥) | FTH | **pacted to one of the Seven** — the "Pact Mark" talent lends the party a sliver of a lord's blood-price power |
+| **Hedge-Mage** (Wizard) | MAG | **outsider** — arcane is *studied*, not worshipped; serves neither side (the deliberate contrast: knowledge vs devotion) |
+| martials (Sellsword / Trapper / Barbarian) | STR/DEX | **unaligned** — the war only *echoes* (e.g. the rage-calling resonates with **Kareth**), never a pact |
+
+**Warlock name resolved: `Bloodsworn`.** A gritty village folk-name (matching Cutpurse /
+Trapper / Hedge-Mage / Bonesetter) that encodes `rule.blood-price` directly. This closes
+**one** of the two `[CANON-TBD]` calling names in the races/classes spec; the **Barbarian ⚔**
+name stays open (out of scope — this pass handles only the FTH axis). Applying the name to
+the calling data is an **M4** task; here it becomes canon flavor.
+
+**How it lands in content (no new schema):** there is no "class" namespace in the bible,
+and callings are **code-owned state** (races/classes spec) — the bible must not invent a
+class entity. The alignment is carried as **prose inside the two rule entries**:
+`rule.the-pact` notes that a devout mortal (the Bonesetter) can channel the Warden's
+blessing; `rule.blood-price` notes that the Bloodsworn borrow a lord's power through the
+pact (the Pact Mark). Callings are named in prose, never entities.
+
+**Creation hook (flag, M4 — not decided here):** a Bloodsworn may choose **which of the
+Seven** is patron, flavoring the Pact Mark. Optional; belongs to the M4 creation
+brainstorm, not this content pass.
+
+**The Luck-immunity — the §7-sensitive flag (NOT built here):** the user's intent — *"the
+Seven do not spend misfortune on their own sworn"* — is **safe to state as lore flavor**
+and will appear in `rule.blood-price` / the Bloodsworn's flavor. But any **mechanical**
+Luck carve-out is **deferred and must be reconciled**, because:
+- the settled resolution model states **"LCK is the only randomizer… cannot leak onto the
+  character sheet as a number,"** and §7 forbids the player ever being able to *calculate*
+  they are cursed. A hard "immune to bad luck" toggle bumps both.
+- The **§7-safe route** (to be designed at the combat/Improviser brainstorm, ~M5): the
+  effect lives in the **Improviser** — allegiance *weights* boon-vs-humiliation selection
+  (prose, not combat numbers) — and it **costs a blood-price** (the pact is never free).
+- **Decision:** author the flavor now; build no Luck mechanic. Flag it for M5/Improviser.
+
+**§2 accounting:** callings remain state (code owns them). This pass adds only *text the AI
+narrates from* (rule bodies, flavor) — no AI system mutates a calling or a Luck value.
+Consistent with §2.
