# Pre-v1 escape hatch (see reg_meta_build/DESIGN.md → Slug immutability)

While this file exists in `reg_meta_build/fqid_slugs/`, slug renames and removals
flow through `precheck-slugs --update-snapshot` instead of being refused,
and the `test_no_removed_or_renamed_slugs` snapshot test skips its rename
guard. Diffs are still reported so drift stays visible.

The point is to encourage curation iteration before v1 — fixing typos,
normalizing conventions, splitting siblings — without per-rename ceremony.

At v1 release: **delete this file**. The grow-only guarantee then re-arms
across CLI, tests, and CI.
