 ## How it works
 
-- A note is a zettel when its filename starts with a **TIMEID**: a run of 12 to 18 digits
-  (a timestamp) followed by any non-digit or the end of the name - so `20260728145404-my-note.md`,
-  `202607281454.md`, and even `202607281454 my note.md` all qualify. Files without that prefix
-  are ignored, so plain notes, daily notes, Excalidraw and Kanban files are never renamed.
-- The TIMEID is minted **once** and never changes. Only the slug tail is regenerated.
+- A note is a zettel when its filename starts with a recognized **prefix**: a **TIMEID** (a run
+  of 12 to 18 digits) always, and a **`yyyy-mm-dd` date** too if you enable date mode in settings.
+  The prefix is followed by any non-digit or the end of the name - so `20260728145404-my-note.md`,

 - Sync is strictly one-way, H1 to filename. Renaming a file by hand is never fought.
-- Delete the H1 and the filename collapses back to the bare `TIMEID.md`.
+- **Sticky tail:** the tail follows the H1 when it produces a slug; with no H1 the existing tail
+  is kept and cleaned. The tail is never deleted - delete the H1 and the filename keeps its last
+  slug. A note that never had a title stays bare (`TIMEID.md`); one with no usable title (empty
+  H1 and no sluggable tail) is left untouched.
+- If a rename would collide with an existing filename, zettelclean keeps the current name and

 The slug is case-preserving, ASCII, dash-separated: accents are folded (`Ciências` becomes
 `Ciencias`), runs of punctuation and whitespace collapse to a single dash, and leading and
