# `mix mailglass.docs.check`
[🔗](https://github.com/szTheory/mailglass/blob/v1.0.0/lib/mix/tasks/mailglass.docs.check.ex#L1)

Fail the build if Tier 1 docs leak internal IDs or drift away from the
canonical stability-contract story. The checks are deterministic and scoped
to release-blocking docs only.

## Usage

    mix mailglass.docs.check
    mix mailglass.docs.check --path "guides/**/*.md"

Exits 0 if clean. Raises with `Delivery blocked: ...` brand-voice
message if any internal ID is found.
