+
+### a_locally_resolved_page_scroll_lands_where_the_host_would_put_it
+
+**What was missing (improvise-5xbq).** `tests/lockstep.rs` compared only `j`
+and `G` against the host. The browser's page rule (`resolve::page_rows`) and
+the TUI's (`Move`'s `Page` arm, `visible_rows * 3 / 4`) were two copies, and
+two faults injected into the browser's copy left the whole workspace green:
+`page_rows` returning `window_rows / 2`, and `grid_move` paging by
+`window_cols`. The second was invisible for a further reason: the only window
+the page-rule test used was square, `(8, 8)`.
+
+**The fixture.** 20 rows by 3 columns; the host sees 8 rows and the client
+announces `(8, 3)`. The three candidate rules then give three different
+steps: 6 (three quarters of the rows), 4 (half the rows) and 2 (three quarters
+of the columns). The walk starts off the edge (two `j`), then presses `PgDn`,
+`PgUp`, `Ctrl-d` and `Ctrl-u`, including a `PgDn` that clamps at row 19.
+
+**Why it pins the rows as well as comparing the ends.** `page_rows` is now the
+one home (the TUI's `Move` calls it), so a wrong rule moves host and client
+together, and a comparison alone passes. Each press therefore also asserts the
+row the TUI's rule names.
+
+**Injected, before and after the move to one home.**
+
+| Fault | Two copies | One home |
+|---|---|---|
+| `page_rows` returns `window_rows / 2` | fails at press 2 (`PgDn`), "client and host disagree" | fails at press 2, "not the row the TUI's page rule names"; `app.rs`'s `page_down_scrolls_by_three_quarters_visible` and `page_up_scrolls_backward` fail too |
+| `grid_move` pages by `window_cols` | fails at press 2, "client and host disagree" | fails at press 2, "client and host disagree" |
+
+`Ctrl-d`/`Ctrl-u` are `scroll-rows ±5`, not the page rule. They are in the walk
+because the ticket named them, and they move the start point of the next page
+turn to a row the fixed rules alone would not reach.
+
+### a narrow window still shows how to page through help — `harness/tests/help.spec.js`
+
+**What broke (improvise-1c5m).** Below the width at which the app bar wraps,
+`#help` (fixed, `inset: 2rem`, `z-index: 30`) covers `#hint`, and since PR #180
+Welcome carries no paging instruction of its own. So a new user on Welcome at
+phone width could not see how to reach page two.
+
+**The fix is option (b) from the ticket.** The overlay draws `model.hint` in a
+footer. In Help mode that is already `hint_line(Help)`, the same string `#hint`
+carries, so it adds no derivation, and it sits outside `.help-body`, so
+"Welcome is prose" still holds. The footer is `position: sticky` because the
+overlay itself scrolls and Welcome is longer than a phone-height overlay.
+
+**What the case asserts.** At 600x800 on Welcome, it reads the hint string from
+`#hint`, so the spec spells no keys. It then requires some element showing
+exactly that string to be the topmost element at its own centre, which is the
+`elementFromPoint` measurement the ticket made by hand.
+
+**Red, then a rival.** At base it failed with "the paging hint is under the
+help overlay". With the fix and `position: sticky` changed to `static`, it
+fails the same way: the footer exists but sits below the fold of a scrolling
+overlay, so presence alone cannot satisfy the case.
