1. // components/search.hl — `/search` and `/search/<text>` (tracker.worldapi.org#14). Creator's words: "in the actionbar a
2. // search symbol that first checks our database and then has a fetch from web button that actually searches tmdb then for
3. // things we dont have yet". The header's search icon (components/main.hl) opens this page.
4. //
5. // * OUR DATABASE as you type: every keystroke asks the face `searchDb` (search.hl's in-memory index — no table scan) and the
6. // lists are replaced whole; the address follows the text (`history.replaceState` → `/search/<text>`), so a reload or a
7. // shared link opens the same results, rendered on the server. Titles (series + movies, with the year) and people (tracker#37:
8. // with their photo, each → their page).
9. // * "Fetch from web": the face `searchWeb` asks TMDB (search/multi) and lists the titles we DON'T have yet; "Add" imports
10. // one (`searchImport`: a new show, then the daily sync's own `syncShow` — seasons, episodes, poster, ids) and opens its
11. // page. Signed out, "Add" opens the sign-in modal and sends nothing; searching itself needs no sign-in.
12. //
13. // THE ADDRESS: `/search/<text>`, not `/search?q=` (the architect's reading) — hl:web gives a page its route's path params
14. // but no query string, so the text travels as the route param `q`. A full page load gets it already decoded by the server, a
15. // client-side navigation still encoded — search-helpers.hl `queryOfParam` decodes what is left. '/', '?', '#' go into the address
16. // as spaces (see searchTyped).
17. //
18. // HYBRIEL TRAPS (mission 052): hybriel#121 (rows appended after a session face appear twice) — no list here is ever
19. // appended to, every list is replaced whole; hybriel#122 (after a session face, members using a route param + session are
20. // re-derived without the route param) — no member reads both: the results come from `q` alone, the sign-in state from
21. // `session` alone, and the only session face (`searchImport`) answers no list. The gate checks the lists after a failed
22. // import (a session face that stays on the page).
