fix(web): keep a paged window and an item panel on the user's newest intent - #645
Conversation
A write claims its ticket before it starts, so a load-more still in flight is superseded and its response discarded — correct. But the click behind it was never withdrawn, and `refreshWindow` re-walked only to `cursorRef`, the cursor as it stood before that click. The page the user asked for was silently dropped, and the record the write just created could land in the gap beyond the rebuilt window. Track the furthest offset the user has ASKED for alongside the one the server has settled, and walk to whichever is further. The ask counts only while it is still reachable: a landed load, an extension the server refused, and a refresh walk that emptied the window all retire it, so one failed page cannot become a request re-issued on every later write. Affects all ten adopting screens equally; the hook is where the rule lives.
`refreshAll` ended by re-activating the item the write was about, from an
id captured when the handler ran. The panel's own Close link carries no
`disabled={busy}`, so it stays reachable behind the dialog for the whole
flight (#480's virtual-cursor door): closing the panel mid-write put the
user straight back onto the item they had just left, when the write
settled.
Read which item is open from a ref at the moment the re-read lands, and
drop the captured `openItemId` that every caller was threading through
`run` — with the ref there is nothing left for it to say. That removes the
staleness rather than testing for it, and the panel now follows the user's
newest choice on every write path, including the two (create, edit) that
never passed an id at all.
A `null` stays authoritative: an open item the refresh no longer lists
closes the panel, as before.

@coderabbitai full review Context for the round: both changes are async-intent fixes, so the interesting surface is interleaving, not syntax.
Verification already run and reported in the PR body: full SPA suite 2211/2211, typecheck clean, and a snapshot-restored mutation check on every load-bearing line (9 mutants; 8 die on their own named assertion, the 9th is disclosed as equivalent-by-construction). |

Found by the CodeRabbit review of #645, and pre-existing rather than new here: `reload` starts the replacement but leaves `cursorRef` at the previous filter's depth until the new page lands. A write that supersedes that in-flight replacement then walks the NEW filter to the OLD filter's depth — pages the user never asked for under a filter they have only just arrived at, and a failure on one of them empties a window whose first page was good. Retire both cursors at the moment a replacement is issued. The rows on screen are deliberately left alone: whether to blank them is a per-screen presentation choice expressed through `reloading`, whereas these two are server cursors and the server has just been asked to start over. Verified pre-existing: with this PR's `requestedCursorRef` removed from the walk's target, the new test still fails on `cursorRef` alone. This PR's change extended the over-walk by one page whenever a load-more was pending at the same time; it did not create it.
Confirmed and fixed in One correction to the attribution: this predates the PR rather than arriving with it. The fix. Both cursors are retired at the moment a replacement is issued, in Tests, both of the shape you asked for — a multi-page filter A window, a write superseding an unresolved filter B replacement:
Mutation check, snapshot-restored, baseline and restore both green:
Each half is independently load-bearing, which is why the middle two mutants matter: either cursor left standing alone reproduces the finding. Full SPA suite 2213/2213, typecheck clean. On the second half of your review — no additional panel-refresh issue in Not re-triggering a review round for this: the loop's stop rule is the owner's call and this round has now confirmed one real product defect, so the next round is worth having only if a human wants it. |

Closes #629. Closes #630.
Two independent async-intent defects, both found by the #511 review round (PR #628) and both pre-existing there. One lives in
usePagedListand affects all ten adopting screens; the other is InventoryPage's own.#629 — a write during an in-flight load-more dropped the page the user asked for
runWriteclaims its ticket before the write starts, so a load-more still in flight is superseded and its response discarded. That part is right. But the click behind it was never withdrawn, andrefreshWindowre-walked only tocursorRef— the cursor as it stood before that click. The page the user asked for was silently swallowed, and the record the write had just created could land in the gap beyond the rebuilt window.The hook now tracks the furthest offset the user has asked for beside the one the server has settled, and the post-write walk goes to whichever is further. The ask counts only while it is still reachable: a landed load, an extension the server refused, and a refresh walk that emptied the window all retire it — so one failed page cannot become a request re-issued on every later write.
Not addressed here: part 2 of the issue (the one-render window before
reloadingflips). It is an opt-in per-screen presentation choice, bounded to a single paint, and identical for every existing adopter.#630 — a write's refresh re-opened the item panel
refreshAllended by re-activating the item the write was about, from an id captured when the handler ran. The panel's own Close link carries nodisabled={busy}, so it stays reachable behind the dialog for the whole flight (#480's virtual-cursor door): closing the panel mid-write put the user straight back onto the item they had just left when the write settled.It now reads which item is open at the moment the re-read lands, and the captured
openItemIdis gone fromrefreshAllandrunentirely — with the ref there is nothing left for it to say. That removes the staleness rather than testing for it, and covers the two write paths (create, edit) that never passed an id at all. Anullstays authoritative: an open item the refresh no longer lists still closes the panel.A correction to the issue's repro. #630 describes opening item B while the POST is in flight. That is not producible — every row's Open button is
disabled={busy}for the whole write. The reachable door is the panel's Close link, and that is what the test drives.Verification
