The Slice-0 vertical that proves the enforcement architecture end-to-end. - kernel: castSpell (slot consumption + concentration set/replace, upcasting, warlock pact slots), spendResource/regainResource, rollDeathSave — pure functions returning Partial<Character> patches. 13 unit tests. - applyRest now ends concentration on any rest (+ test). - character sheet SpellcastingSection: per-spell Cast button, concentration banner with Drop, concentration markers; ResourcesSection −/+ routed through the kernel. - player MyCharacterPanel: castable spell list + concentration banner, so a seated player casts and it broadcasts via the existing playerPatch flow. - live sync: partialCharacterDiffSchema carries concentration; GM applies it; playerCharacterSchema mirrors slots/concentration/resources (PC-only) and the player-facing AC now respects equippedArmor. Wire round-trip test added. Verified live: casting decrements the right slot, switching concentration logs "Concentration on X ends", banner + Drop render. Build + 258 tests green.

TTRPG Manager
A local-first campaign manager for D&D 5e and Pathfinder 2e, built for both Game Masters and players. Runs entirely in the browser (installable as a PWA) — your data lives in IndexedDB on your device; no account, no server.
Features (MVP)
- Campaigns — create per-system campaigns; deleting one cascades to all its data.
- Characters — 5e/PF2e sheets with live derived stats: ability modifiers, proficiency, skills, saves, AC, initiative, HP (with damage/heal/temp). Autosaves.
- Combat tracker — initiative order, round/turn tracking, conditions, HP, and add/remove/reorder mid-fight without ever corrupting whose turn it is.
- Dice — full notation (
2d6+3,4d6kh3), advantage/disadvantage, seedable RNG, per-campaign roll history. - Compendium — searchable SRD bestiary, spells, and magic items. Add any monster straight into the open encounter.
Tech
- React 19 + TypeScript (strict) + Vite
- TanStack Router · Zustand · Zod · Dexie (IndexedDB) · Tailwind v4 · Fuse.js
- Vitest (unit) + Playwright (e2e), PWA via vite-plugin-pwa
Architecture
src/
lib/
rules/ # game-system abstraction — 5e & pf2e behind one RulesSystem interface
combat/ # pure, tested turn-order + HP engine
dice/ # notation parser + roller
db/ # Dexie schema + repositories (cascade deletes, validation on write)
schemas/ # Zod entity schemas — every number rejects NaN/Infinity
compendium/ # lazy SRD data loaders (code-split out of the main bundle)
features/ # campaigns, characters, combat, dice, compendium (UI)
components/ui/ # design-system primitives
data/srd/ # SRD JSON (Open5e + MPMB); regenerate with scripts/fetch_data.py
The rules layer means features never branch on if (system === '5e'); they call the
RulesSystem interface, so adding a system is a self-contained module.

Roadmap
Notes/journal, maps with fog of war, encounter/loot builders, a shared player view, PF2e compendium data, and an optional sync backend for real-time tables.
History
This is a from-scratch rebuild. The previous implementation (deleted) had ~135
documented bugs and no version control; its bug report is kept at
docs/OLD_BUG_HUNT_REPORT.md as a record of failure modes designed against here
(silent data loss, turn-order corruption, no cascade deletes, NaN inputs, dead
Tauri integration). The SRD data and Python scrapers were preserved.
