The selection is restored from localStorage, but it was only validated once
at mount. Deregistering the selected source left App holding an id that no
longer exists, so every subsequent call 404'd "Source not found" with no way
out but a reload — Setup.deleteSource clears its own selectedSource and never
tells App. Deleting the selected version had the same shape.
Move both checks into effects keyed on the lists themselves. A sourcesLoaded
flag keeps the source effect from firing against the initial empty array and
wiping the restored id before the fetch resolves.
Also coerce both refresh callbacks to an array. A 401 returns an error object,
and data.some() then threw inside an unhandled promise, stranding the
selection instead of clearing it.

Document the outcome of the Option C spike (server-side DuckDB as a
Perspective virtual server) and the resulting architecture decision.
pf_perspective_options.md:
- Spike findings: latency is excellent (~12ms round trip, 5-29ms
aggregation, ~1.5-1.9s to materialize 534,902 rows) but Perspective's
GenericSQLVirtualServerModel ignores group_by_depth and has no
ViewConfig field for per-node expansion state, so interactive
drill-down is not achievable. This affects options B, C and D alike
since they share that SQL model.
- Decision: the real lever is grain, not transport. Pre-aggregating to
display grain collapses 534,902 -> 4,642 rows (~115x) on osm_stack
while keeping the native Perspective engine, so expand/collapse/
depth/sort/filter continue to work.
- Two candidate designs (Path A live virtual server vs Path B
pre-aggregated extract) with the deciding question: do real cuts ever
exceed the browser's leaf-row ceiling?
pf_spec.md:
- Concrete Path B design: pf.col_meta.in_grain, GET /api/versions/:id/agg,
synthetic pf_gkey index, and the append-deltas write/undo model that
mirrors the prior Excel pivot-cache workflow.
Drop pf_ux_mockup.md — an ASCII mockup of UI that is now built; the
views in ui/src/views are the current reference.

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
