A naming conflict (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/intents/drafts/itd-14-prompt-registry-versioning.md:29 — "Per-prompt version field (## Prompt Version: X.Y)"
• End B: .abcd/development/brief/05-internals/05-prompt-quality.md:41 — "prompt_version present and a valid semver, on every prompt."

itd-14 records a prompt's version in a ## Prompt Version: X.Y body field. 05-prompt-quality requires a prompt_version frontmatter key holding a valid semver on every prompt, and agent_contract enforces it. The version marker has two names and two formats.
