 ## Decision

-Electron + React + TypeScript + Vite; SQLite with JSON documents for systems/characters; portable `app/shared` contract for future TTRPG Player + mobile.
+Electron + React + TypeScript + Vite; JSON file store (`userData/store.json`) for systems/characters; portable `app/shared` contract for future TTRPG Player + mobile.

 ## Rationale

-Matches TTRPG Player packaging targets; offline-first; no Postgres.
+Offline-first; avoids native module rebuild (better-sqlite3) requiring Visual Studio on Windows.

 # ADR-002: Formula DSL

-## Decision
-
-Custom minimal expression language (`floor`, `ceil`, `round`, `min`, `max`, `clamp`, arithmetic, `attr.*` / `skill.*` / `resource.*` / `derived.*`).
-
-## Rationale
-
-Same evaluator can be copied into the player; explicit rounding; no heavy CEL/JSONata dependency.
+Custom minimal expression language with explicit rounding; portable to the player.

 # ADR-003: Schema freeze via snapshotHash

-## Decision
-
-Player binds store `snapshotHash` (content-addressed) rather than inline full schema per character.
-
-## Rationale
-
-Implements freeze-on-bind without bloating `players.json`.
+Player binds store `snapshotHash` rather than inline full schema per character.

 # ADR-004: Spells from dnd.su

-## Decision
-
-Provide an import pipeline for PHB-labelled spells from dnd.su at product owner request, with README/IP disclaimer. Prefer SRD stubs in default presets.
-
-## Rationale
-
-Owner requested PHB coverage; redistribution risk acknowledged.
+Import pipeline for PHB-labelled spells at product owner request, with IP disclaimer. Default presets ship SRD stubs.
