test: intentionally broken lightshow submission (NAT-131)

[tallnato]

Summary

• Adds an intentionally invalid lightshow entry to test the CI validation pipeline
• Contains 4 intentional validation errors:
  1. Missing audio field — required for lightshows category
  2. Missing .fseq file — required file type for lightshows
  3. Invalid tag fake-tag — not present in content/tags.yaml
  4. Bad slug Test_Broken_Lightshow — uses uppercase and underscores instead of lowercase-hyphens

Expected outcome

• validate-pr.yml and validate-lightshows.yml should fail
• validate-single-component.yml should pass (only one collection touched)

Test plan

• Verify CI checks run on this PR
• Confirm validation errors are caught and reported
• If checks pass unexpectedly, investigate and document why

CI Results ✓ (Expected Failures)

Both validate-pr.yml and validate-lightshows.yml failed as expected, catching 3 validation errors:

#	Error	Validator
1	folder name must be lowercase alphanumeric with hyphens (got "Test_Broken_Lightshow")	validateSlug
2	unknown tag "fake-tag". Add it to content/tags.yaml first.	validateMeta
3	missing required field "audio"	validateAudioField

Note on missing .fseq file

The missing .fseq file was not flagged as a separate error. The validateFiles function only errors when the directory has zero files or when a file has a disallowed extension. Since test-audio.mp3 is present and .mp3 is an allowed extension for lightshows, no file-type error was raised. The validator does not enforce that a .fseq file must exist — it only validates that existing files have valid extensions.

Other checks

• validate-single-component.yml — passed (only lightshows collection touched)
• Semantic PR — passed
• label — passed

PR Review — Approved ✅

This test PR accomplishes its stated goal. CI correctly catches 3 of 4 intentional validation errors:

Error	Caught	Notes
Bad slug (Test_Broken_Lightshow)	✅	Uppercase + underscores flagged
Invalid tag (fake-tag)	✅	Not in tags.yaml
Missing audio field	✅	Required frontmatter field
Missing .fseq file	❌	Validator checks extensions, not required file types

Observations:

• PR structure follows the expected slug.md + slug/ directory pattern
• validate-single-component.yml correctly passed (only lightshows touched)
• The .fseq gap is a real validator limitation worth tracking separately
• No security concerns, no secrets in the diff

Recommendation: Merge as-is for CI validation documentation, or close without merge if test data shouldn't persist on main. The fake test-audio.mp3 (plain text "fake audio data") should not land on main long-term.
