+## Lessons from sec05 (2026-09-22) — what made the 7 rescues possible / what to do next time
+
+1. **User oracle table = highest-ROI step.** Initial ❌ list (19) was 37% wrong; user checked the
+   RU-title-guess table against OZON/labirint memory and rescued 7. **Convention: at section end,
+   present the ❌ table (author, EN title, guessed RU author/title, channels probed) to the user**
+   before finalizing MISSING.md.
+2. **RU titles are NOT calques** — the actual titles found: «Очерки сравнительного РЕЛИГИОВЕДЕНИЯ»
+   (not «религии»), «Аспекты мифа» (translated from FRENCH *Aspects du mythe*, not from EN *Myth and
+   Reality*), «Модели культуры» (not «Узоры/Образцы культуры»), «Потерянный мир Калахари» (the
+   «Затерянный» variant is a DIFFERENT book — Bjerrre). Always probe 2–3 RU title variants;
+   for authors with FR/DE originals (Eliade, van Gennep) also try the FR/DE-based RU title.
+3. **rutitles diff was SKIPPED for sec05 and would have caught 3/7 rescues** («Аспекты мифа»,
+   «Культурный комплекс», «На пороге инициации» were all in data/ru-titles.jsonl from the cogito
+   crawl). **Mandatory: `tools/rutitles.py both "<EN title>"` for every item before ❌** (added to
+   the negatives gate below).
+4. **flib authorall for prolific RU authors** (Элиаде a/2943 = 49 books) caught «Тайные общества»
+   (sec05 #13) that libgen title search missed. Always run flib author sweep for authors with
+   >5 RU books.
+5. **libgen mislinked-file trap**: edition 141685581 «На пороге инициации» carried an ePubLibre
+   Spanish Lermontov file. Before downloading, check the file `locator`/title via
+   `json.php?object=f&addkeys=*&ids=<fid>`; for recent books prefer flib (cleaner metadata).
+6. **Collection-inclusion questions** (#27/#28): download the smallest fb2, parse the TOC
+   (`<section name="title">`), grep for the EN book title + RU calque. «Символ и ритуал» (Наука
+   1983) CONTAINS «Ритуальный процесс» (full text, core section) but NOT «Лес символов»
+   (citations only).
+7. **flib pdf download**: `/b/<id>/pdf` may return an HTML stub; `/b/<id>/download` → 302 →
+   direct `static.flibusta.is:443/b.usr/<File>.<ext>` URL — curl that directly.
