# decord — data branch


Auto-generated by `main`'s `update (hourly)` workflow (`src/update/tasks/decompile.ts` + `code.ts`). Do not edit manually.

## Contents

- `code.js.gz` — full decompiled bundle (`hermes-decomp decompile`)
- `index.android.bundle` / `.hdcache`
- `module-paths.json` — `[{id, path}]` extracted from `code.js` via `fileFinishedImporting("...")`
- `source.jsonl` — `{file, size}` index
- `source/` — `16492` modules (`hermes-decomp extract` + path mapping)
- `version.txt`

## `source/` layout

`10030` Discord-owned modules have a real path (`fileFinishedImporting`) and are placed at their source path:
`modules/` (7291), `discord_common/` (501), `discord_assets/`, `utils/`, `actions/`, etc.

`6468` modules have no path in the bundle and are sharded semantically to avoid GitHub's 1000-file dir limit (`NNxxx = id//1000`):

- `__helpers/NNxxx/` — `~460` Babel/RN helpers (`_typeof`, `_isNativeReflectConstruct:182`, `__INTERNAL_VIEW_CONFIG`)
- `__vendor/NNxxx/` — `~2558` vendor/barrels (`1000_feedbackAsyncIntegration`, `items`, `prop`, `formatDistance`, Sentry/Reanimated)
- `__polyfill/NNxxx/` — `~3439` opaque `module_*.js`
- `6` root files with path but no `/` (`index.native.tsx:0`, `Constants.tsx:653` etc) stay at root

Each `NNxxx` bucket is `<1000` (max `961` in `02xxx` polyfill).

## Why some are "unmapped"

`fileFinishedImporting` is only emitted for Discord source. Helpers/vendor are required at runtime (`dependencyMap`) but are not part of Discord's repo, so no path exists. See `src/update/tasks/code.ts:54 resolveDest()` and `classifyUnmapped()`.
