+# temporal-hijri — PRI (Per-Repo Instructions)
+
+**PPI:** `~/Sites/acamarata/.claude/CLAUDE.md`
+
+## What This Is
+
+Temporal Calendar Protocol implementation for the Hijri calendar. Works with the TC39
+Temporal proposal and `@js-temporal/polyfill`. Provides `UaqCalendar` (Umm al-Qura) and
+`FcnaCalendar` (FCNA/ISNA) as plug-in calendars for `Temporal.PlainDate` and related
+types. The underlying conversion logic comes from hijri-core.
+
+**npm:** `temporal-hijri@1.0.0`
+**Language:** TypeScript
+**License:** MIT
+
+## Key Technical Details
+
+- Peer dependencies: `hijri-core@^1.0.0`, `@js-temporal/polyfill@^0.4.0` (optional)
+- `@js-temporal/polyfill` is optional — works with native Temporal when available in the runtime
+- Key exports: `uaqCalendar` (singleton), `fcnaCalendar` (singleton), `UaqCalendar` class, `FcnaCalendar` class
+- Calendar protocol methods: `year()`, `month()`, `day()`, `monthCode()`, `inLeapYear()`, `dateFromFields()`, `dateAdd()`
+- UAQ data covers 1318-1500 AH (Gregorian 1900-2076)
+- Dual CJS/ESM build via tsup
+- Zero runtime dependencies (peer deps are provided by the consumer)
+
+## Architecture
+
+`src/index.ts` exports calendar singletons and classes. Built to `dist/` (gitignored)
+with `.cjs` and `.mjs` outputs plus dual type declarations. No format string parsing —
+the Temporal API handles all date arithmetic and formatting natively.
+
+## Commands
+
+- `pnpm install` — install dev deps
+- `pnpm build` — tsup build
+- `pnpm test` — run test.mjs + test-cjs.cjs
+- `pnpm run typecheck` — tsc --noEmit
+
+## Important Notes
+
+- This implements the Temporal Calendar Protocol — it is not a general-purpose Hijri utility
+- hijri-core provides the actual calendar engine — this package is a thin Temporal protocol adapter
+- Changes to hijri-core's API may require updates here
+- `@js-temporal/polyfill` is optional — only needed in environments without native Temporal support
+- TC39 Temporal proposal is Stage 3 — API may shift; track spec changes carefully
