Adds PUT /versions/:id/baseline/:logid that, in one transaction, drops
the segment's rows and log entry and replays the baseline or reference
SQL with new params. The endpoint refuses (409) if any scale, recode,
or clone has been applied — those operations were calibrated against
the old totals and would silently misreconcile.
Baseline view gets an Edit button on each segment (hidden once
forecast operations exist), populating the form with the original
filters, offset, and note. Submit issues PUT in edit mode, POST
otherwise. POST baseline and POST reference now also persist the
structured filters in pf.log.params so edit can reload them.

Save/restore went through both viewer and plugin, where the explicit
plugin.restore could stomp the column formatting the viewer had
already applied. Capture via viewer.save() alone (it includes
plugin_config) and restore via a single viewer.restore call with
edit_mode merged in. Added a perspective-config-update listener so
formatting, sort, and other in-place changes persist to the last-used
cache without an explicit Save.

The slice panel was a single muted line; now it shows a breakdown
table — value, units, and derived price for baseline / scale / recode /
clone, with a bold total row when more than one iteration applies.
Numbers use full text contrast so the current state is legible at a
glance during adjustments. Scale gains a price input that holds units
constant and translates to a value-target call (target value =
new_price × current_units).

Reuse a single Perspective worker across version switches and delete
the previous table instead of terminating the worker — terminate was
returning a rejecting promise the sync try/catch missed, and each new
worker leaked WASM memory. applyLayout no longer leaks a view per call;
it reads schema directly from the table. An init id guards against
concurrent runs (StrictMode, rapid version switches) clobbering each
other, and a catch on "already exists" recovers via open_table+delete
when a stale table from a previous run is still hosted.

App.jsx owns sources/sourceId/versions/versionId and persists them
across reloads. StatusBar renders the dropdowns plus a status badge —
Source-only on Setup, Source · Version · status on Baseline/Forecast.
The duplicate in-view selector bars in Forecast and Baseline are gone;
Baseline keeps its version actions (New/Close/Reopen/Delete) inline.
Setup reports source-list mutations up via refreshSources so the bar
stays in sync after register/deregister.

App chrome now uses Pro Dark's neutral grays (#242526 background,
#2a2c2f panels, #4c505b borders) so the surrounding UI sits cleanly
against the viewer instead of clashing with its warmer tone. Status
accents are desaturated to match. Forecast view sets theme="Pro Dark"
or "Pro Light" on the perspective-viewer in sync with the toggle.

Perspective table is now created with index: 'pf_id'. Delete endpoints
return the pf_ids they removed; the client calls table.remove(pf_ids)
in undoEntry. Avoids the full /data refetch that dominated undo time.

pg now returns bigint/numeric as JS numbers so Arrow infers Int/Float64
instead of Dictionary<Utf8>. /data accumulates rows and emits a single
record batch to avoid dictionary REPLACEMENT messages that crash
Perspective's WASM reader. Forecast view streams the response body and
shows received/total bytes while loading. Drops stale public/ static
middleware that was shadowing the React build at /.

Server streams rows from a pg cursor in 10k-row batches, building Arrow
record batches incrementally and piping them as chunked HTTP response —
Node.js heap stays bounded regardless of dataset size.
Client fetches as arrayBuffer() and loads directly into Perspective worker
(native Arrow path, no JSON deserialization). X-Row-Count header drives
a non-blocking banner for datasets >= 500k rows. validCols now derived
from col_meta rather than from row keys.

Re-applies fetchCurrentTotals dimension-only filter (prevents Perspective errors
from split_by/expression columns in the filter), toolbar three-group reorganization
(Layout | Expand | Data with dividers), always-visible Save as…, msg in toolbar,
resizable panel, change log modal with undo and inline note editing.

Expression columns (bucket, computed) are defined in cfg.expressions and
are valid pivot axes, but weren't in validCols (raw table columns), so
they were filtered out of group_by/split_by on every layout restore.

- GET /api/versions/:id/log — log entries with row counts via JOIN
- DELETE /api/log/:logid — undo in a transaction (delete fc rows + log entry)
- PATCH /api/log/:logid — update note text
- History button opens a modal: op badge, slice, editable note, row count, Undo per entry
- Undo triggers full Perspective table reload via initViewer

- Fix perspective-click handler to use event filter triples instead of
__ROW_PATH__ — Perspective encodes row position as [col,'==',val] in
detail.config.filter
- buildWhere now skips unrecognised slice keys (e.g. pf_iter) instead of
throwing, so only dimension columns reach the WHERE clause
- Add draggable resize handle on the operation panel (160–480px)

- Baseline.jsx: merge Reference section into Add Segment form with baseline/reference toggle; segment rows now clickable to expand stored WHERE clause + timeline; date filter inputs use type="date" for date-role columns
- Timeline.jsx: add type prop ('baseline'|'reference'); reference band uses purple; single-band height shrinks to 52px; canvas uses requestAnimationFrame to fix offsetWidth=0 on mount
- operations.js: reference route now accepts where_clause like baseline (drops date_from/date_to)
- sql_generator.js: reference SQL template uses {{filter_clause}} instead of hardcoded BETWEEN
Note: existing sources need Generate SQL re-run to pick up the new reference template.

- ui/: React + Vite + Tailwind app (Setup, Baseline, Forecast views, collapsible sidebar, status bar, canvas timeline)
- server.js: serve built UI from public/app/
- package.json: add build script (cd ui && npm run build)
- routes/sources.js: default new col_meta role to 'dimension' instead of 'ignore'
- .gitignore: exclude public/app/ build output
- pf_spec.md: update tech stack, nav, frontend section, and project status to reflect current implementation
