+  Version change: 3.0.0 → 3.1.0 (MINOR — new principle II-A: context-based state flow)
   Modified sections:
-    - Development Workflow: specs are living feature documents; full pipeline for new features only
+    - Core Principles: added II-A. Context-Based State Flow (max 8 props, context over prop drilling)

+### II-A. Context-Based State Flow

+UI components MUST consume shared application state via React context
+providers, not prop drilling. Props are reserved for per-instance
+configuration (e.g., a specific data item, a layout variant, a ref).

+- Components MUST NOT declare more than 8 explicit props in their
+  own interface. This is enforced by `scripts/check-component-props.mjs`

+- Generic UI primitives (`components/ui/`) that extend HTML element
+  attributes are exempt — only explicitly declared props count, not
+  inherited HTML attributes.
+- Coordinating hooks that consume multiple contexts (e.g.,
+  `useInitiativeRolls`) are preferred over wiring callbacks through

 - **Domain events** are plain data objects with a `type` discriminant — no classes.
 - **Tests** live in `packages/*/src/__tests__/*.test.ts`. Test pure functions directly; map acceptance scenarios and invariants from specs to individual `it()` blocks.
 - **Feature specs** live in `specs/NNN-feature-name/` with spec.md (and optionally plan.md, tasks.md for new work). Specs describe features, not individual changes. The project constitution is at `.specify/memory/constitution.md`.
+- **Component props** — max 8 explicitly declared props per component interface (enforced by `scripts/check-component-props.mjs`). Use React context for shared state; reserve props for per-instance config (data items, layout variants, refs).
 - **Quality gates** are enforced at pre-commit via Lefthook's `pnpm check` — the project's single earliest enforcement point. No gate may exist only as a CI step or manual process.

 ### Edge Cases
 
 - User pins a creature and then that creature is removed from the encounter: the pinned panel continues displaying the creature's stat block (data is already loaded).
-- Active combatant changes while panel is open or collapsed: advancing turns does not auto-show or update the stat block panel. The panel only changes when the user explicitly clicks a book icon. If the panel is collapsed, it stays collapsed.
+- Active combatant changes while panel is open: if the new active combatant has a creature, the panel auto-updates to show that creature's stat block. If the new active combatant has no creature, the panel remains on the previous creature. If the panel is collapsed, it stays collapsed. If the panel is closed, it stays closed.
 - Viewport resized from wide to narrow while a creature is pinned: the pinned (left) panel is hidden and the pin button disappears; resizing back to wide restores the pinned panel.
 - User is in bulk import mode and tries to collapse: the collapse/expand behavior applies to the bulk import panel identically.
 - Panel showing a source fetch prompt: the pin button is hidden.
