Session probe lands on /vw_pages (Research). Use main designlang extract
with --cookie-file — pack ignores auth. 39 artifacts under
docs/design-extract; tolerate designlang late summary crash when cores exist.
Ran authenticated extract against coulomb.social; session metadata
matched anonymous Bubble defaults, so treat docs/design-extract as a
public shell baseline (PROVENANCE.md). Capture script now refuses to
overwrite storage-state.json with thin anonymous sessions.
