Pull request overview
Adds a new developer-facing design sketch proposing a lockfile-based mechanism to preserve synthetic history across upstream history rewrites (force-push) and distro branch advances with divergent history, so %autorelease/%autochangelog remain monotonic and prior changelog eras aren’t silently dropped.
Changes:
- Documented the failure mode in the current synthetic-history pipeline when pinned commits become unreachable.
- Proposed a “transition” record in lock files to explicitly bridge discontinuities, plus UX guardrails (
update --allow-discontinuity) and render-time validation. - Included a TOML example and pointers to current implementation hotspots for future work.

This was originally deferred until we needed it for branch changes, but recently we discovered that some dist-gits rewrite their history, we need a mechanism to bridge discontinuities in linear history.
