THE root cause of "watch history delete does nothing / card vanishes then pops
back": the profile modal's history renderer overrode `remove` to route through
onHistoryReady -> app.handleProfileHistoryEvent(), which is a stub that just
`return null`. So deleting an item in the profile history pane published NOTHING
— the card was removed optimistically, then the refresh re-rendered the full
list and it reappeared. No publish, no logs, no relay change.
This explains why earlier fixes (replace semantics, newest-per-d-tag read,
empty-month publish) didn't help — they were all on the standalone history path /
the publish layer, but the profile pane never reached any of them. The override
was almost certainly a placeholder left over from the synced-vs-local history
refactor that was never implemented.
Fix: drop the broken `remove` override so the profile history pane falls through
to the renderer's working default (defaultRemoveHandler -> snapshot +
updateWatchHistoryList with replace:true) — the same path the standalone view
uses. Validated manually (UI wiring); regression test to backfill.
Build + full lint green.
