## Summary
- replace the whole-tree file-size gate with a stateless differential
ratchet
- allow inherited files over 1,000 lines to hold or shrink, but never
grow
- delete the 44-entry numeric override ledger and run the same policy
across Desktop, Web, and Mobile CI
- fail closed when the local base cannot be resolved and cover policy,
Git status parsing, and base resolution in unit tests
This removes the shared mutable policy state that caused unrelated PRs
to fail after neighboring merges. It does **not** by itself prevent two
stale green PRs from becoming invalid when combined; that requires merge
queue or up-to-date branch enforcement.
### Related issue
None found. This follows the design discussion in the linked Buzz
channel.
### Testing
- `node --test scripts/check-file-sizes-core.test.mjs` (6/6)
- Desktop, Web, and Mobile ratchet entrypoints
- `just desktop-check`
- `just web-check`
- Mobile analysis
- `git diff --check`
The repository pre-push suite also exposed an unrelated existing Mobile
widget failure in `ChannelDetailPage keeps follow mode off while a tall
newest message stays visible`; it reproduces in isolation and this
branch does not touch Mobile widget behavior.
