Phase 17 splits the four files that hold most of the code, finishes the
schema migration SP8 left half done, and stops the published guide from
drifting away from its Markdown source. `plan/17-refactor.md` carries the
plan and the progress table, and `plan/STATUS.md` points at it.
Stage 0 is hygiene only. Both abandoned worktrees are gone, which freed
about 104 MB. Removing `sp7-tree-ui` needed one extra step: a Vite dev
server had been running out of it since 2026-08-18, holding
`frontend/.vite` open and owning port 5173, and serving a tree 54 commits
behind `main`. The three stale `.db` files are deleted; `data.db` is not.
`AIDND_TRUSTED_PROXY_HOPS` is now documented. It was read at `limits.py:55`
and named in no `.env.example`, README, or blueprint. It sets how many
proxy hops the rate limiter trusts in `X-Forwarded-For`, so a deployment
that adds a hop without setting it gets the bucket-rotation bypass back.
The 19 squash-landed branches are still there. `git branch -D` is blocked
by the permission classifier; the verified command is in the plan file.
549 tests pass.
