BUG: openspec validate --strict succeeds, but openspec archive fails validation

[wreed4]

I'm getting these errors on archive

Proposal warnings in proposal.md (non-blocking):
  ⚠ Requirement must contain SHALL or MUST keyword
  ⚠ Requirement must have at least one scenario
  ⚠ Requirement must contain SHALL or MUST keyword
  ⚠ Requirement must have at least one scenario
  ⚠ Requirement must contain SHALL or MUST keyword
  ⚠ Requirement must have at least one scenario
  ⚠ Requirement must contain SHALL or MUST keyword

But validate succeeds with no issue. The headers in question I THINK are because my agent put in extra headers into the spec

### Documentation Requirements     <---- I think this is the issue

### Requirement: AI Application Documentation

Teams building AI applications SHALL document agent definitions, prompts, and integration patterns.

#### Scenario: Agent Definition Documentation

while I could just get my agent to stop doing that, and I probably will, I don't think the validation should succeed with openspec validate and fail when I go to archive it.
