**Warning** from the compiler, while it builds your `.tsrx` files.

## What happened

`markless-allow` silences warnings only. The code it names is an error.

Markless prints the message, the reason, and a suggestion:

```text
MARKLESS_ALLOW_ERROR_UNSUPPRESSIBLE: markless-allow named <code>, but <errorCode> is an error and must still be fixed.
markless-allow is a per-site escape hatch for warning diagnostics only; it must stay readable and current for the next person editing the site.
Fix the diagnostic or remove the markless-allow comment.
https://markless.dev/errors/MARKLESS_ALLOW_ERROR_UNSUPPRESSIBLE
```

Words in angle brackets change from case to case.

## How to fix it

Fix the error. Then delete the `markless-allow` comment.

If you accept the warning on purpose, put this comment on the line above it:

```tsrx
// markless-allow MARKLESS_ALLOW_ERROR_UNSUPPRESSIBLE: the reason you accept it
```

## Where it comes from

`@markless/compiler` raises this code. Source:
