docs: the guide around four things and two screens, new screenshots, the plan closed

The guide opens with documents, cards, notes and diary entries, and the
documents and plan screens, then walks the day with the scratchpad, the
info sheet and cards linked both ways. The README and the wiki's home say
the same in short, and show the scratchpad and the info sheet. The
screenshot script drops its Alt keys and takes both. PLAN.md records the
simplification's slices, what was left of its navigation fixes, and the
backlog fitted to the model.

 # Findings, possible bugs, and what comes next
 
-Written on 2026-10-21, after the seven slices of the feature plan had landed
-(trash `8ffad63`, revisions `fc2be66`, links `a42f907`, capture tokens
-`f629f5a`, diary `824f2bb`, recurring cards `6673298`, search in files
-`909abf5`). That plan has fully landed, and git keeps it.
+## The simplification, done
 
-These came out of writing the wiki, taking the screenshots against a fresh
-workspace, and probing the API on a throwaway server. All of them are fixed
-now, except two limits of search noted at the end of the list.
+Written on 2026-10-22. The app had grown slice by slice to about 85 commands,
+60 browse keys and 11 overlays, with the same idea modelled two or three times:
+text in three editors, files in two places, cards that pointed at a document
+the document could not see, four inboxes, two layout systems, and keys
+documented by hand in seven places. A plan in eleven slices made the same
+features out of fewer things, one place for each, and one key grammar. Every
+one has landed:

+| 1 | one keymap table drives the dispatch, help, the footers, the rail and the wiki; a mode stack replaces the flags | `0eabcb2` |

+| 8 | `!` means force or everything only; merged commands; a settings sheet; two-level help | `7f8d625` |
+| 9 | the store split into parts under one `Workspace` | `b110701` |

+
+The model it leaves: a **document** is the thorough record, a **card** the
+short actionable summary of work, a **note** a thought not sorted yet, and a
+**diary entry** a document about a day. A file sits in a folder or belongs to
+its document. The documents and the plan each have a screen, and the
+scratchpad comes down over either.
+
+### Left over from the plan, not started
+
+These were in the plan's navigation fixes, outside the numbered slices:
+
+- The list groups documents by day in every space; the plan had that only in
+  the diary, and folders first then by name elsewhere.
+- `Ctrl-P` is full-text search across every space; the plan had it become a
+  jump to a node by its name and path, with `Tab` in `/` reaching every space.
+- A card's notes are made in the space's root, not in the folder being
+  browsed.
+- `o` does not offer the space's templates; `:new <template>` does.

 ## Next, unplanned
 
-Carried over from the last plan, still not started:
+The backlog, fitted to the model rather than given new surfaces:
 
 - Install the app on a phone (a PWA: manifest plus a service worker for the
   app shell, CSP `worker-src 'self'`), with a share target that posts into
-  capture. The new icon is ready for the manifest.
-- Task lists: toggle `- [ ]` in the reader, and `:tasks` gathers the open ones
-  in a space.
-- A daily review in the agenda: yesterday's entry, what was finished this week,
-  and cards in `doing` for more than 14 days.
-- Marks: `ma` … `mz` per document, `'a` to jump. This clashes with `m` for
-  picking nodes up, so choose the keys first.
-- Mail-in capture: IMAP polling of a plus-address into the inbox.

-Suggested next: the PWA, which the new icon makes cheap.
+Dropped: marks (`ma` … `mz`). The info sheet's headings and the tiles cover
+what they were for, and `m` stays picking nodes up.
