Description

Threat model files in System.Private.Uri/docs use 2 trailing spaces for hard line breaks (standard markdown syntax). Configured MD009 rule to recognize this instead of suppressing entire files.

Changes

  • Set br_spaces: 2 in .markdownlint.json to allow 2-space line breaks
  • Removed file-based suppression approach (.github/workflows/markdownlintignore)
  • Reverted workflow changes that referenced the removed ignore file

This properly handles the semantic meaning of trailing spaces rather than blanket-suppressing files from linting.

✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.

@copilot Let's configure markdownlint to ignore 2 spaces instead of suppressing individual files

See https://github.com/markdownlint/markdownlint/blob/main/docs/RULES.md#md009---trailing-spaces

The two spaces in this case are hard line breaks, not random spaces

Description
Threat model files in System.Private.Uri/docs use 2 trailing spaces for hard line breaks (standard markdown syntax). Configured MD009 rule to recognize this instead of suppressing entire files.
Changes
  • Set br_spaces: 2 in .markdownlint.json to allow 2-space line breaks
  • Removed file-based suppression approach (.github/workflows/markdownlintignore)
  • Reverted workflow changes that referenced the removed ignore file
This properly handles the semantic meaning of trailing spaces rather than blanket-suppressing files from linting.
✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.
