Evergreen update 🌿

Two pushes made to fix this PR:

1. Rebase onto main — the branch was 11 commits behind; rebased cleanly with no conflicts.

2. TypeScript fix — resolved 5 type errors that were failing the Test & Lint check:

   • src/io/xml.ts: Added Label import; filter undefined from Scalar[] before passing to Index constructor (fixes TS2345)
   • tests/io/read_table.test.ts: Use Index.size instead of non-existent .length (fixes TS2339 ×2); simplified always-undefined sep expression (fixes TS2379); changed df.filter(["a","c"]) → df.select(["a","c"]) (fixes TS2322 ×2)

The Playground E2E (Playwright) failure appears to be a timeout flake unrelated to code changes. CI should pass on the new HEAD.

Evergreen CI Fix

Push 1 — Rebase onto main (11 commits): cleanly rebased with no conflicts.

Push 2 — TypeScript fixes for the Test & Lint failures:

• src/io/xml.ts: Import Label type and filter undefined from Scalar[] before passing to Index constructor (fixes TS2345)
• tests/io/read_table.test.ts:
  • df.columns.length → df.columns.size (Index has no length property, use size) (fixes TS2339 ×2)
  • Remove explicit { sep: undefined } which violates exactOptionalPropertyTypes (fixes TS2379)
  • df.filter(["a", "c"]) → df.select(["a", "c"]) (filter takes a boolean mask; select takes column names) (fixes TS2322 ×2)

Playground E2E: The failure was a Playwright 30s timeout (forFunction waiting for Run buttons) — a transient infrastructure issue, not a code bug. This should resolve itself on re-run.

Evergreen Fix

I've addressed the issues on this PR with two pushes:

Push 1 — Rebase onto main (11 commits behind)

Cleanly rebased the branch onto main with no conflicts.

Push 2 — Fix TypeScript type errors

The Test & Lint CI was failing due to 5 type errors:

src/io/xml.ts:402 — Scalar[] is not assignable to readonly Label[]

• Added Label import and filtered idxData using a type guard before passing to Index constructor (Scalar includes bigint | undefined | TimedeltaLike which are not valid Label types)

tests/io/read_table.test.ts:134, 172 — Property 'length' does not exist on type 'Index<string>'

• Changed df.columns.length → df.columns.size (Index exposes .size, not .length)

tests/io/read_table.test.ts:253 — sep: string | undefined not assignable with exactOptionalPropertyTypes

• Removed the always-undefined conditional sep option

tests/io/read_table.test.ts:298 — string[] not assignable to readonly boolean[]

• Changed df.filter(["a", "c"]) → df.select(["a", "c"]) (filter takes a boolean mask; select is the column-selection method)

The Playground E2E timeout failure is a flaky infrastructure issue unrelated to the code changes.

Push 2 — Fix TypeScript errors: The Test & Lint check was failing due to typecheck errors introduced in the latest iterations:

• src/io/xml.ts: Filtered undefined from Scalar[] before constructing Index (type mismatch with Label[])
• tests/io/read_table.test.ts:
  • Changed df.columns.length → df.columns.size (Index has .size, not .length)
  • Changed df.filter(["a", "c"]) → df.select(["a", "c"]) (filter takes a boolean mask; select takes column names)
  • Removed always-undefined sep option from property test (violated exactOptionalPropertyTypes)

The Playground E2E failure appeared to be a 71-second timeout on an old SHA — likely a resource-constrained runner on the previous CI run. The rebase and fixes should resolve both failing checks.
