# X_CONFIG_READER_PIN_UNEXPLAINED

## Means

an `AppConfig` leaf key is pinned with a blank reason

## Typical cause

`Object.hasOwn` asked whether a row EXISTS and never whether it said anything, so a key pinned with an empty string silenced the rule outright — the waiver axiom 3 refuses. Both tables in the file are guarded, `CONFIG_READER_PINS` and `CONFIG_AMBIGUOUS_PINS`

## Fix

write who reads the key — a file under `packages/`, or a surface outside this repo — in `scripts/lib/config-reader-pins.ts`; or delete the key from `packages/core/src/config.ts` and from `defaults()`
