refactor(systems): one definition per play system drives counters and formats by mchisolm0 · Pull Request #359 · HashingSeeds/scryve

mchisolm0 · 2026-10-09T17:59:21Z

Game-system rules lived in three registries that drifted: src/features/game/playSystems.ts (counters), convex/lib/deckGames.ts (formats and sections), and convex/lib/integrations.ts (providers and rights), plus ~115 inline system === "mtg" / format === "commander" checks. Brawl fell through the gap: a new Brawl game started at Magic's generic 20 life instead of 25 (CR 903.12).

Approach

convex/lib/systems/ holds one SystemDefinition per system, as const satisfies Record<SystemId, SystemDefinition>:

labels, available, defaultFormat: { deck, play }
counter: label/plurals, default value, presets, steps, direction: "open" | "down", max start
formats[]: id, label, blurb, deck sections, and capability flags startingValue, hasCommanderDamage, singleton
integration: identity namespace, capabilities with providers (card catalog, deck import, images...), rights

SystemId, FormatId<System>, and CatalogProvider are derived from the data. Helpers: isSystemId, systemDefinition, formatDefinition, hasCommandZone.

The three registries keep their exported API but now read from it. No api.* names, args, or return shapes change.

Brawl: startingValue: 25, multiplayerStartingValue: 30, singleton: true, and an explicit hasCommanderDamage: false, since CR 903.12 drops the 21 commander damage loss. Commander damage stays Commander-only.

defaultStartingLife now takes a player count. New Game and Settings recompute a starting value still at its default when the player count changes, the same way they already did on system and format changes.
A stored Brawl default of 20, saved before Brawl had its own default, migrates in parseSettings to 25 or 30. Without that, 20 would read as a custom value, and switching to Commander would stay at 20 instead of 40.

Migrated

src/features/game/playSystems.ts: starting life and commander damage come from format flags. Prize "taken" copy keys on counter.direction rather than system === "pokemon".
convex/lib/cardImageFallback.ts: dispatches on the card catalog provider, type-checked against every provider.
convex/lib/games/archidekt.ts: ["commander", "brawl"].includes(format) became hasCommandZone.
convex/lib/deckGames.ts: game !== "mtg" became a Scryfall catalog check.
convex/integrationManifest.ts: no more as cast. integrationFor infers its literal return type, so integrationManifest.list keeps main's narrow types. A @ts-expect-error test guards this.
convex/_generated/api.d.ts: hand-added the two new lib modules (codegen avoided because it uploads to the shared dev deployment).

Left for follow-ups

Inline checks still live in these files (counts from grep): convex/deckImports.ts 17, convex/deckCatalogs.ts 17, src/screens/AddDeckScreen.tsx 15, convex/cards.ts 11, src/screens/GuestDeckDetailScreen.tsx 10, src/screens/DeckDetailScreen.tsx 10, src/features/decks/commanderSelection.ts 5, convex/games.ts 5, src/features/decks/useCardDetails.ts 3, convex/decks.ts 3, convex/cardCatalog.ts 3, src/screens/DecksScreen.tsx 2, src/features/decks/DeckView.tsx 2, src/features/decks/CardSearchScreen.tsx 2, src/components/Screen.tsx 2, src/screens/NewGameScreen.tsx 1, src/features/decks/guestDeck.ts 1, src/features/decks/DeckCardRow.tsx 1.

Other places where Brawl is missed, all outside this PR's files:

Commander choice and the one-copy commander lock are gated on format === "commander", so Brawl decks can't pick a commander in the deck editors. Affected files: DeckDetailScreen, GuestDeckDetailScreen, AddDeckScreen, features/decks/CardSearchScreen, DeckCardRow. These should use hasCommandZone. Commander legality would also need a Brawl source.
NewGameScreen defaults Commander matches to best of 1 but Brawl to best of 3.
convex/games.ts commander damage gates are correct for Brawl but still inline.

Evidence

pnpm compile, pnpm lint:check on the changed files, and full jest pass. Under load, analytics.test.ts and deckCatalogs.test.ts hit timeouts but pass on their own. New focused tests cover the Brawl flags, Commander-only commander damage, counter direction, and default formats.

Web pass on /dev/seed/game (Playwright, local dev server):

Seed	Before tap	After tap
Commander, 4p, cmd 2>3:9	40 life, commander damage shown	39
Brawl, 2p, no `start`	25 life, no commander damage controls	24
Brawl with `cmd=`	seed rejected: "cmd needs system=mtg&format=commander"	n/a
Pokémon	6 Prize cards	5
Yu-Gi-Oh!	8000 Life Points	7900

Brawl Commander Pokémon Yu-Gi-Oh!

Summary by CodeRabbit

New Features
- Default starting life reflects the selected game, format, and player count, including multiplayer Brawl settings.
- Changing a game, format, or player count updates starting life when it matches the previous default; customized values are preserved.
- Game integrations and card image sources follow each game’s configured capabilities.
Bug Fixes
- Saved Brawl settings using the former default starting life are updated for the player count.

📝 Walkthrough

Walkthrough

The pull request adds shared definitions for supported game systems and uses them to derive integrations, deck and play rules, and catalog-provider behavior. Game setup and settings calculate default starting values using the selected format and player count. Saved Brawl settings receive a migration.

Shared game systems

Layer / File(s)	Summary
System definitions and lookups `convex/lib/systems/*`	Defines formats, counters, capabilities, and integration metadata for Magic, Yu-Gi-Oh!, and Pokémon. Adds system and format lookup helpers and tests these definitions.

Shared play rules and starting values `src/features/game/playSystems.ts`, `src/features/game/playSystems.test.ts`, `src/devtools/seeds/gameSeed.ts`	Derives play rules from shared definitions and calculates starting values from the selected format and player count.
