Event data is parsed deterministically; there is no model call, API key or per-run cost anywhere in the pipeline. A source that cannot be parsed deterministically gets no adapter rather than an inference fallback. Documents the parser/adapter/merge split, records that Game8 uses three page templates, and adds Neverness to Everness. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>

# Data Model
|
|
|
|
`src/shared/schema.ts` is the single source of truth. TypeScript types are derived with
|
|
`z.infer<>` — never hand-write an interface that duplicates a schema.
|
|
|
|
## The Event
|
|
|
|
```ts
|
|
import { z } from "zod";
|
|
|
|
export const GameId = z.enum([
|
|
"genshin", "hsr", "zzz", "wuwa", "arknights", "endfield", "nte",
|
|
]);
|
|
|
|
export const EventType = z.enum([
|
|
"banner", // limited character/weapon rate-up
|
|
"story", // main or side story chapter, limited-time
|
|
"rerun", // returning event
|
|
"challenge", // combat/endgame cycle (Abyss, Memory of Chaos, ...)
|
|
"login", // login rewards / check-in
|
|
"shop", // limited shop or exchange window
|
|
"maintenance", // server downtime
|
|
"other",
|
|
]);
|
|
|
|
export const Region = z.enum(["asia", "america", "europe"]);
|
|
|
|
/** How much we actually know about a boundary timestamp. */
|
|
export const Precision = z.enum([
|
|
"exact", // sourced to the minute
|
|
"day", // date known, time-of-day inferred from the game's reset
|
|
"unknown", // genuinely not announced — endsAt is null
|
|
]);
|
|
|
|
export const GachaEvent = z.object({
|
|
id: z.string(), // `${game}:${slug}:${YYYY-MM-DD}` — see Stability below
|
|
game: GameId,
|
|
title: z.string().min(1).max(200),
|
|
type: EventType,
|
|
summary: z.string().max(500).nullable(),
|
|
|
|
startsAt: z.string().datetime(), // UTC ISO 8601, always
|
|
startPrecision: Precision,
|
|
endsAt: z.string().datetime().nullable(),
|
|
endPrecision: Precision,
|
|
|
|
/** True when the end time follows each region's daily reset rather than a global instant. */
|
|
regionScoped: z.boolean(),
|
|
/** Populated only when regionScoped; per-region resolved UTC instants. */
|
|
regionEnds: z.record(Region, z.string().datetime()).nullable(),
|
|
|
|
sourceUrl: z.string().url(),
|
|
sourceId: z.string(), // which adapter/source produced this
|
|
|
|
status: z.enum(["published", "delisted"]),
|
|
confidence: z.number().min(0).max(1),
|
|
extractionMethod: z.enum(["parser", "manual"]),
|
|
|
|
version: z.number().int().positive(),
|
|
firstSeenAt: z.string().datetime(),
|
|
updatedAt: z.string().datetime(),
|
|
});
|
|
|
|
export type GachaEvent = z.infer<typeof GachaEvent>;
|
|
```
|
|
|
|
### Field notes that matter
|
|
|
|
**`endsAt: null` is a first-class state, not an error.** Many events are announced with "duration
|
|
TBD" or "until the next version update". The correct representation is `endsAt: null` with
|
|
`endPrecision: "unknown"`. The extractor is instructed to produce this and the UI renders it
|
|
distinctly (PRD F1). Filling in a plausible date instead is the single worst bug this codebase can
|
|
ship.
|
|
|
|
**`regionScoped` + `regionEnds`.** Character banners end at one global instant — `regionScoped:
|
|
false`, `regionEnds: null`. Story and login events end at each region's daily reset — `regionScoped:
|
|
true`, with `regionEnds` carrying the three resolved UTC instants. The client picks one using the
|
|
user's stored region (PRD F5). Collapsing these into a single timestamp loses up to 13 hours of
|
|
accuracy and will make the countdown wrong for two thirds of users.
|
|
|
|
**`confidence`** is assigned by the parser and adjusted during merge and reconciliation — see
|
|
`docs/INGESTION.md` § Scoring. It records how firmly the sources pinned the event down.
|
|
|
|
**`status: "delisted"`** means the event stopped appearing at its source. It is never deleted,
|
|
because a source outage would otherwise silently empty the calendar. Delisted events are excluded
|
|
from the API feed but retained for debugging and for the case where a source flickers.
|
|
|
|
### ID stability — read before changing
|
|
|
|
```
|
|
`${game}:${slugify(title)}:${startsAt.slice(0, 10)}`
|
|
→ "genshin:windblume-festival:2026-03-14"
|
|
```
|
|
|
|
**Event IDs are the localStorage keys for completion state.** Changing the scheme orphans every
|
|
completion mark every user has ever made, silently, with no error and no way to recover it
|
|
server-side (the server never had the data). If the scheme must change, ship a client-side
|
|
migration that reads the old keys and remaps them, and keep that migration for at least a year.
|
|
|
|
The date suffix disambiguates reruns of the same event. Title is slugified from the *source's*
|
|
title, so a wiki renaming an event creates a new ID — reconciliation detects this as a near-match
|
|
(same game, overlapping dates, high title similarity) and treats it as an update rather than a new
|
|
event, preserving the original ID.
|
|
|
|

```
|
|
|
|
`region_ends` and `payload` hold JSON as TEXT; parse them through the Zod schema on read so a
|
|
malformed row surfaces at the boundary rather than deep in the UI.
|
|
|
|
## Client-side storage
|
|
|
|
Namespaced, versioned, and small. Nothing here ever goes to the server.
|
|
|
|
```ts
|
|
"gacha-tracker:v1:completions" // { [eventId]: { completedAt: string } }
|
|
"gacha-tracker:v1:prefs" // { region, hiddenGames[], hiddenTypes[], showCompleted }
|
|
"gacha-tracker:v1:feedCache" // { fetchedAt, events } — offline fallback
|
|
```
|
|
|
|
The `v1` segment is the migration hook. On boot, the client checks for keys at older versions and
|
|
migrates them forward before reading. **Never delete an old-version key until the migration has
|
|
shipped and run** — a user who has not opened the app in six months still has their data under the
|
|
old key.
|
|
|
|
### Export format (PRD F6)
|
|
|
|
```json
|
|
{
|
|
"format": "gacha-tracker-export",
|
|
"version": 1,
|
|
"exportedAt": "2026-08-14T12:00:00.000Z",
|
|
"completions": { "genshin:windblume-festival:2026-03-14": { "completedAt": "..." } },
|
|
"prefs": { "region": "europe", "hiddenGames": [] }
|
|
}
|
|
```
|
|
|
|
Import **merges**: a completion present in either the file or the current device stays completed.
|
|
Import never removes a completion. Losing a user's marks to a bad import is unrecoverable, so the
|
|
merge is deliberately one-directional.
|
|
|
|
## Schema versioning
|
|
|
|
`/api/events` responses carry `{ schemaVersion: 1, generatedAt, events: [...] }`. The client
|
|
refuses to render a `schemaVersion` it does not know and shows a "refresh the page" prompt instead
|
|
of guessing at unfamiliar fields. Additive fields do not bump the version; removing or retyping a
|
|
field does.
