# ROOT_HISTORY.txt — append-only record of manifest root hashes
#
# Every time the manifest root changes (because a definition was re-cut,
# an artifact was added, or a correction was made), the old root is
# appended here with the dates it was live. This keeps old crawl evidence
# meaningful: a November reader can verify today's root AND check that
# August's crawl matches a root we still acknowledge.
#
# A root that appears in a crawl but not in this list is either a
# forgery or a root we've disowned — either way, it's not our claim.
#
# Format: root_hash  live_from  live_to  chain_version  notes
