 ## Immediate Next Moves
 
-1. Implement the responsive polish pass in `feat/responsive-polish`, focusing on mobile and small-laptop typography and spacing without changing content.
+1. Implement historical artifact governance in the next feature branch, focusing on the final treatment of `README.CRAWL.md` and any similar repo-only files.
 2. Keep `scripts/render_heatmap.py` and `Figure2-Teeth_v4.1.pdf` in sync if the figure changes.
 3. Run `python scripts/check_homepage.py` against `_site/index.html` after a local build if you need a homepage smoke check.

 ### 1. Browser smoke test for the home page
 
+- Status: merged to main.
 - Goal: add a browser-driven verification path that opens the local site, checks the title, the main heatmap image, the download link, and the image alt text.
 - Merge boundary: the test harness and its docs only.
 - Verification: browser screenshot or a scripted browser run against the local preview.
 - Why first: it gives every later feature a stable visual baseline.
 
 ### 2. Responsive polish pass
 
+- Status: merged to main.
 - Goal: harden the layout for mobile and small laptop widths without changing content.
 - Merge boundary: CSS and minimal markup only.
 - Verification: browser screenshots at desktop and mobile breakpoints.
 - Why second: it keeps later content changes from conflating with layout regressions.
 
 ### 3. Historical artifact governance
 
+- Status: next.
 - Goal: decide the final treatment of `README.CRAWL.md` and any other historical artifacts.
 - Merge boundary: docs and navigation only.
 - Verification: non-UI validation plus live site check that the artifact is not surfaced publicly.
