…signed entries Adds `crosslink integrity sign-backfill [--confirm] [--key PATH]` which retroactively signs unsigned hub entries with a human's SSH key. This attests that missing signatures were a system error, not unapproved commits. - Dry-run by default; --confirm to apply signatures - Uses separate "crosslink-backfill" namespace to distinguish from original agent signatures - Registers human key in allowed_signers as backfill@crosslink - Updates verify_entry_signatures to recognize backfill signatures via fallback principal check - Handles both V1 inline comments and V2 standalone comment files Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
