PR #4 of the v0.7.x GUI rework arc. Production code; central-gui restart only.
- Adapter legend: collapsed by default ("{n} adapters · Show legend ▾"). Expands
to domain-grouped chips (same grouping as the v0.7.1 chip-picker) with uniform
ellipsis-truncated names + full-name title tooltips. Clicking a legend chip
toggles that adapter's filter (reuses the chip-picker's hidden CSV via
syncField), so the legend doubles as a filter affordance.
- Row stability: time cell is single-line MM-DD HH:MM UTC (year dropped from the
cell; full ISO in the cell tooltip + a new Time row in the expanded detail).
Adapter cell is a chip (color swatch + short name; display_name is the
tooltip). table-layout:fixed + per-column widths + fixed 37px row height with
nowrap/ellipsis cells -> no per-row wrap variation.
- Real paginator: _fetch_events offset-mode returns the exact page slice plus the
grand total via count(*) OVER() in one roundtrip. Previous/Next + windowed page
numbers (1 ... 4 5 [6] 7 8 ... 47) + "showing X-Y of N" + a 25/50/100/250
per-page selector. URL state persists offset + limit. events.json keeps cursor
pagination (back-compat): offset param presence selects offset-mode, its
absence keeps the cursor path -- cleanly separable by endpoint.
Adds TestEventsPagination (12 tests: offset/limit parse incl. max 250,
offset-vs-cursor query shape, _build_pagination windowing). Updates the time
format + adapter-cell + pagination-mode assertions in the existing frontend
tests to the new contract.
Full suite: 674 passed, 1 skipped (central and unprivileged zvx). count(*) OVER()
is ~7.5ms at current volume; vanilla JS + HTMX; CSS functional-only.
