Publishing or handing over an artifact now checks whether its source changed since it was last read, instead of assuming it's still current

What

  • The artifact hand-over/auto-read guard now checks whether the source changed since it was last read; if so, it returns a new outcome, own_version_source_changed, instead of silently proceeding on the client's own version.
  • The set of reasons an artifact or page can be withheld now includes a new sourceChanged reason, alongside existing ones like gone and otherOrg.
  • When publishing an update, if the current file is recorded as this session's own source for that artifact, its recorded version matches what's live, and it hasn't been read as a "workshop page", publishing now proceeds without forcing a fresh stale-version check, and logs telemetry for that auto-proceed decision.

Why

This prevents Claude Code from silently overwriting an artifact whose source has actually changed elsewhere, while still allowing a fast republish when republishing your own unchanged work.
