 ### Checklist
 
-- [ ] Define the canonical purpose of each top-level directory in one sentence.
-- [ ] Confirm `PROJECT/` is only for planning, tracking, inbox, working, and done states.
-- [ ] Confirm `temp/` is for sensitive and disposable runtime artifacts, not long-term reference docs.
-- [ ] Define what qualifies for `experimental/` and what conditions trigger promotion out of it.
-- [ ] Define which report outputs belong in-repo versus gitignored runtime storage.
-- [ ] Review `.gitignore` coverage for reports, screenshots, scans, auth state, and logs.
-- [ ] Write simple retention rules for generated content: keep, archive, or purge.
-- [ ] Decide what must always have an owning doc or README in dense directories.
