Co-owned repositories can now use --allow-t3 for one explicitly approved CLI invocation, including rendering and organization planning. The default still refuses T3 owners, and the flag does not lift excluded-owner or hold restrictions. Pick Your AI gets its own palette, mark, badge colors, organization attribution, and brand-aware license rendering.

The changes were rebased onto current main while preserving the newer lint argument parsing and registry-free label-planning behavior. No private registry data, publication defaults, shared package validators, or release settings change.

Prior work

Searched repository issues and pull requests for Pick Your AI, T3, and showcase work. No existing PR covers the T3 invocation scope or this brand family. Open #13 addresses variant-J badge generation and parsing; its separate work is preserved. Merged #18 supplies the Windows test portability fixes included in this branch's base, and merged #17 supplies the label-planning behavior preserved during rebase.

Validation

• The original prepared checkout reproduced exactly the recorded 15 baseline failure IDs: 15 failed, 922 passed, 13 skipped, 37 subtests passed.
• Full suite after rebase: 980 passed, 13 skipped, 37 subtests passed; no failures.
• Focused T3 and configuration tests: 45 passed.
• python scripts/validate_package.py: passed.
• python scripts/validate_quality.py: passed; Mermaid and pyright checks unavailable as reported by the validator.
• Package unittest suite: 23 tests, 2 skipped, passed.
• scripts/validate_package.py and tests/test_package_contract.py remain byte-identical to main and both inspected sibling skills.
• Fresh VM verification: not run. Validation above ran on the Windows host; hosted CI is separate evidence.

No merge or release is requested. Owner decisions about repository metadata, licenses, and README content remain separate from rendering support.
