THE root cause of the entire 'still reloads / still not working' saga
across 2.7 -> 2.8 -> 2.8b: shop_tags.j2 (tag_bulk.js) and
product_edit.j2 (product_tags.js) loaded their <script> WITHOUT the
?v={{ request.git_hash }} cache-bust. routes.py serves /static with
cache_max_age=3600, so the operator's browser kept the STALE JS for up
to an hour after every deploy — the new SPA code never executed, forms
fell back to native submit = full page reload, every time. Server-side
functional tests passed throughout because they have no browser cache.
Fix: append ?v={{ request.git_hash }} to EVERY static <script> include
(the established base.j2 / offer.js / pay-countdown.js convention) —
not just the two at fault but the whole latent class: tag_bulk,
product_tags, tag_filter, auction, player, sandbox, watch, signals,
comments, shop-settings. request.git_hash shifts every deploy -> URL
changes -> fresh fetch, no hard-refresh ever needed again.
Gate (must be empty):
grep -rnE '<script src="/static/js/[^"?]+\.js"' make_post_sell/templates/
The 2.8/2.8b JS (onTagFormClick unified click handler, AJAX focus,
drag-to-reorder) stands — it just was never being fetched by the
browser. 1131 tests pass. Docs: mps-24.md Phase 2.8c, CLAUDE.md
(new mandatory cache-bust convention section).
