Two gaps in how the pivot reports a selection. Dragging across cells did
nothing, and a selection built from several ctrl-clicks was invisible on
the grid — the panel listed the slices but nothing on screen said which
cells they came from.
Drag-select
- The perspective-select handler was reading detail.selected and
detail.insertConfigs. In 5.2.0 that event carries a ViewWindow —
{ start_row, end_row, start_col, end_col }; insertConfigs only appears
on perspective-global-filter, and only in SELECT_ROW_TREE mode. So the
handler always returned early and the whole path was dead.
- It fires on every mouseover as the region grows, so the handler now
records the latest window and a window-level mouseup commits it. A
single-cell region is skipped there: perspective-click already owns
plain and modifier clicks, and handling it in both places would undo a
ctrl-click toggle. Modifier+drag adds to the selection.
- Turning a region back into slices re-derives, per cell, the same
filters Perspective attaches to a click — row dimensions from the
view's __ROW_PATH__, column dimensions from the split_by segments of
the column name. Reading the path rather than the rendered cell is
what keeps dates as epoch millis instead of whatever the grid
formatted them as. The grand-total row resolves to no dimension at
all — that would mean the whole version — and is skipped.
Highlight
- The datagrid already highlights whatever sits in its own
model._selection_state.selected_areas, and wipes that list on every
mousedown, so a multi-click selection only ever showed the last cell.
Keep a sliceKey -> rectangles map parallel to `slices` and push the
full set back after each change, which gets the native highlight for
every selected cell without any styling of our own.
- Deselecting anywhere — ctrl-click, the panel's x, Clear selection —
prunes the map by live slice key, so the grid and the panel cannot
disagree.
Also: edit_mode is forced to SELECT_REGION on restore rather than
defaulted, since a saved layout's plugin_config could previously
override it and turn selection off entirely.

Documentation had drifted far enough to mislead: the spec described the
single-slice panel, the target/delta modes that no longer exist, and the
old `slice` request shape, while both files still claimed Perspective
4.4.0 from a CDN when it has been bundled inline at 5.2.0 since August.
pf_spec.md
- pf.log gains `tag`, with why it is written by a follow-up UPDATE
rather than through the per-source templates in pf.sql.
- Operations envelope documents `slices`, `apply_mode`, and the OR-of-
AND-groups WHERE clause (and why it cannot be flattened to IN lists).
- Scale documents per-measure resolution and `target_basis`, plus the
two guards: non-selective slices, and proration across a ~zero pool.
- New routes: PATCH /log/:logid, table-info, bridge, source tags.
- Forecast View rewritten for the dockable panel and the ledger; adds
the selection caveat around pf_iter and the expand-depth explanation.
- New Bridge View section; Log View gains inline tag editing.
- Status block refreshed, with a Fixed subsection recording the three
correctness bugs and their causes.
- Open Questions: adds bridge drill-down and targeting one iter band;
notes what the bridge partially answers.
CLAUDE.md
- Corrects the Perspective version and the CDN claim.
- Project layout now lists components/, including the two new files.
- Selection section covers multi-select and why duplicate effective
slices are collapsed.

Document the @perspective-dev distribution (not FINOS @finos/perspective):
loader (npm /inline vs CDN), the version trilemma (inline needs 4.5.x,
viewer-d3fc caps at 4.4.1, charts need 4.4.1 — can't have all three),
Arrow vs JSON delivery constraints, deploy pattern, and an upgrade smoke
test. Correct CLAUDE.md's stale perspective.finos.org link to the actual
@perspective-dev repo.

- units role is now optional; spec and CLAUDE.md reflect conditionality in SQL patterns
- pf.col_meta gains dim_group and dim_period_col fields (documented in both files)
- pf.dim_period calendar table added to schema docs
- pf.source default_layout column added to spec DDL
- Forecast table metadata columns corrected to pf_iter/pf_logid/pf_created_at throughout spec
- SQL patterns updated with correct CTE structure and RETURNING * to match generated code
- Project status updated to 2026-06-12; stale Arrow IPC open question removed
- todo.md deleted; open items retained in CLAUDE.md known issues
