1) the-upstream-was-deleted-then-came-back-rewritten (devops, pubDate 2026-10-06)
   docker pull hectorqin/reader -> 404; the repo was re-initialised 2026-09-16 and now
   carries 233 commits, a TypeScript/Node rewrite, port 5888, SQLite /data, config moved
   into the admin UI, and an image on cnb.cool with no tags or releases. Covers telling
   dead from rewriting, the migration boundary, and keeping the front door outside the
   app image. Facts re-verified live 2026-10-06.

2) putting-a-front-door-on-an-app-you-cant-modify (devops, pubDate 2025-06-24 backdated
   into the empty 2025-06 window, updatedDate 2026-10-06 so lastmod stays honest)
   The reader-gateway pattern: a second nginx container owning the public port, the
   request-time resolver, why a proxy body rewrite cannot touch a client-rendered SPA,
   the gate-bounce injection with its pass token, the app's own CSS hook for branding,
   and the silent-failure check to run after every app upgrade.

Both: EN + ZH twins, TERMINALS/BANNERS entries appended via append_generator_entries.py
(additive, deletions 0, node --check OK), og/banner generated and measured PASS
(og rows=1 overflow=0 missingHash=0; banner 8 rows, delta 2, overflow 0).
