Assert preservation of the JSON parse cause.
The malformed second occurrence reaches json.Unmarshal, and parseInlineSpecsOccurrence wraps its error with WithCause(err). This test only checks typed validation metadata. A regression that drops the cause still passes.
Assert errors.As(err, &json.SyntaxError{}) through a typed variable after assertInlineValidationError.
As per coding guidelines: “Error tests must assert typed metadata and cause preservation rather than message text alone.”

Assert that invalid inline input causes no requests or writes.
This test discards the httpmock.Registry and checks only the returned error. Retain the request recorder and assert zero captured calls after each runMountedMailShortcut invocation. The current runner validates before Execute, but this assertion must prevent a future path from performing a side effect and returning the same validation error.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Document large-attachment handling for --attach in all three references.
When the projected EML exceeds 25 MB, +draft-create, +forward, and +reply can upload excess attachments as large attachments instead of embedding them as MIME parts. HTML output receives a download card, while plain-text output receives the filename, size, and download link. Add this behavior to each --attach row and keep the existing 3 GB per-file limit.
