 **Phase 0 — Full names + identity** (`authors/`):
 1. Resolve every initial-only author to a full EN name: `tools/ol.py 'title:"EN Title"'`
    (author_name) → else `tools/wd.py` (QID + RU label) → else Google Books ISBN page →
-   else publisher/review page. Record in `sections/<n>/AUTHORS-EN.md` (EN full name, RU name
-   to query, name source).
+   else publisher/review page. Write/extend the **dossier** `authors/<slug>.md` (EN full
+   name, dates, RU name to query, name source); then add a one-line entry in the thin
+   index `sections/<n>/AUTHORS-EN.md` linking to it. If the dossier already exists from
+   another section, just append the new list item + link it.
 2. For big names: `wd.py` gives life dates + the OFFICIAL RU label (best RSL spelling).
 3. Build the transliteration matrix per author (2–3 variants: Нойманн/Нойман, Кох/Коч,
    Калфф/Кальфф, Ферс/Фёрт) — run every query with ALL variants.
