Summary

Extends scripts/add-spdx-headers.sh with Markdown support (*.md added to the discovery glob, plus an HTML-comment header case), so documents that follow the repo's AGENTS.md header convention — including the pi-rules .github/instructions rule files — can be licensed with the same tooling as the source files instead of by hand.

Problem

The script covers .rs/.typ/.dart/.sh/.feature/.yaml/.yml but not .md, although parts of the docs tree (AGENTS.md files, ADRs, issue notes) carry SPDX headers. The rule files from #339 needed manual header insertion because of this gap.

Solution

• *.md in the find Discovery (recursive, per-directory opt-in as before — the tool is never run repo-wide by CI).
• Markdown headers use HTML comments per the existing AGENTS.md convention.
• Frontmatter-aware: Markdown files that start with YAML frontmatter (pi-rules rule files, future Copilot-style *.instructions.md) get the header inserted after the closing --- delimiter. A header at position zero would degrade the frontmatter to plain body text downstream — a pi-rules rule would lose its glob scope and never inject again. Unterminated frontmatter (a lone leading ---, e.g. a horizontal rule) falls back to plain-markdown handling.
• Already-headered files keep being skipped via the existing SPDX-License-Identifier grep.

Testing

• bash -n syntax check
• Exercised against a temp workspace covering: rule file with frontmatter (header lands after the closing delimiter, frontmatter byte-identical), plain markdown (header prepended), already-headered file (skipped), unterminated frontmatter (plain fallback, no data loss), nested directories, unchanged .yaml/.rs behavior (previously covered)
• gitleaks + commit-format pre-commit hooks pass

Notes

• The tool remains a manual, per-directory convenience (no CI workflow invokes it), so existing unheadered markdown elsewhere is untouched unless someone runs the script on those directories.

📝 Summary

Summary by CodeRabbit

• New Features
  • SPDX and copyright headers are now added to Markdown files.
  • Markdown files with YAML frontmatter retain that frontmatter, with headers inserted afterward.
  • Markdown files without frontmatter receive headers at the top.

Walkthrough

The SPDX header script now processes Markdown files. It writes headers as HTML comments and preserves leading YAML frontmatter by inserting the headers after its closing delimiter.

Changes

Markdown SPDX header support

Layer / File(s)	Summary
Discover and update Markdown files scripts/add-spdx-headers.sh	The file finder now matches *.md files. The script inserts HTML comment headers at the file start or after YAML frontmatter.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 592de

Markdown files with CRLF YAML frontmatter can receive SPDX headers before the frontmatter, potentially breaking metadata parsing. Normalize delimiter lines before merge.
