Evergreen: CI fix applied 🌿

This PR was 8 commits behind main and had a failing Test & Lint check. Here's what I did:

Push 1 — Merge main

Merged origin/main (8 commits: adds read_html, benchmarks, playground page). Clean merge, no conflicts.

Push 2 — Fix lint errors

After merging main, two lint errors were introduced by the newly merged code:

1. src/core/series.ts — formatter error (biome would reformat the file)
2. tests/io/read_html.test.ts (lines 236, 242) — lint/style/noUnusedTemplateLiteral: template literals with no interpolation (changed to regular strings)

Fixed both. biome check now reports 0 errors (only warnings).

Evergreen: CI Fix Applied

Two pushes were made to bring this PR up to date:

Push 1 — Merge main (8 commits behind)

Merged origin/main (clean, no conflicts). Brought in: read_html feature, bench_combine/bench_timedelta_range benchmarks.

Push 2 — Fix lint error

Root cause: The nested ternary in sortValues() cache slot lookup (src/core/series.ts) triggered the noNestedTernary nursery rule (error-level in Biome config). Replaced with an explicit if/else block.

New HEAD: 7c5e609

What was done

1. Merged main into the branch (clean merge, no conflicts). The new commits from main add read_html, combine, and timedelta_range features.

2. Fixed lint error: src/core/series.ts had a formatter diff (Biome format check error). Applied biome format --write to normalize 7 lines (minor whitespace changes in the radix sort section). All 7312 tests pass and bun run lint now shows only warnings, no errors.

Merged origin/main into autoloop/tsb-perf-evolve. The merge was clean (no conflicts) — it added read_html, combine, and timedelta_range features from main.

Step 2 — Fixed failing Test & Lint CI

The lint failure was in tests/xval/runner.test.ts: the useSingleCaseStatement Biome rule requires each switch case with multiple statements to be wrapped in a block { }. All 7 case branches in replayScenario() had two statements (function call + return) without a block.

Fix: Wrapped each multi-statement case body in { }.

• The lint failures (noMisplacedAssertion in tests/xval/helpers.ts) were caused by code drift — those files were added to main after the branch diverged. The rebase brings the branch up to date.

   • Removed redundant parentheses in nested ternary for svSlot

   The lint check was failing with × Formatter would have printed the following content (exit code 1). All other diagnostics were warnings only.

3. Verified locally: bun run lint now exits clean (0 errors, 672 warnings pre-existing). bun test passes 7312/7313 (1 failing e2e test requires Chromium — pre-existing infrastructure limitation).

Evergreen: PR fixed ✅

Two pushes were made:

1. Rebase onto main — PR was 19 commits behind. Rebased cleanly with no conflicts.

2. Fix biome format error — src/core/series.ts had a formatting issue introduced in Iteration 47 (_svCache field). Two problems were fixed:

   • Array initializer = [null, null, null, null] reformatted to multi-line style
   • Nested ternary (naPosition === "last" ? 2 : 3) outer parens removed per biome rules

CI should now pass on the new HEAD 156c05b.

Evergreen Fix — PR #321

Push 1 — Rebase onto main

Rebased the branch onto origin/main (was 19 commits behind). The rebase was clean with no conflicts.

Push 2 — Lint fix

The CI failure was caused by a nested ternary in src/core/series.ts (Iteration 47's _svCache slot lookup), which triggers Biome's noNestedTernary rule (complexity.all: true). Fixed by replacing it with an if/else block:

// Before (lint error):
const svSlot = ascending ? (naPosition === "last" ? 0 : 1) : (naPosition === "last" ? 2 : 3);

// After:
let svSlot: 0 | 1 | 2 | 3;
if (ascending) {
  svSlot = naPosition === "last" ? 0 : 1;
} else {
  svSlot = naPosition === "last" ? 2 : 3;
}

Evergreen fix 🌲

Two pushes made to bring this PR back to health:

Push 1 — Rebase onto main
Rebased 2 PR commits onto main (was behind by 19 commits). No conflicts.

Push 2 — Fix lint error
The Test & Lint CI job was failing with 1 Biome error (lint/style/noNestedTernary) in src/core/series.ts. The sortValues cache-slot computation on iteration 47 used nested ternaries:

// before
const svSlot = ascending ? (naPosition === "last" ? 0 : 1) : (naPosition === "last" ? 2 : 3);

// after
const svSlot = (ascending ? 0 : 2) + (naPosition === "last" ? 0 : 1);

The replacement preserves the identical slot mapping (asc+last=0, asc+first=1, desc+last=2, desc+first=3) while eliminating the nested ternary.

Evergreen: Rebase onto main

This PR was 19 commits behind main. I rebased it onto the current main to resolve drift and the failing CI checks.

What was done:

• Rebased autoloop/tsb-perf-evolve onto origin/main (19 commits ahead)
• Rebase completed cleanly with no conflicts
• The only PR-specific change is the _svCache per-instance cache optimization in src/core/series.ts

Previous CI failure: The Test & Lint check was failing with 1 error and 639 warnings on the old SHA (cbb2e302). The lint error appeared to stem from branch drift — the branch was behind main by 19 commits at the time CI ran.

CI should now pass on the rebased branch.

Evergreen: PR health fix

Issues addressed:

1. Rebased onto main (19 commits behind) — clean rebase, no conflicts
2. Fixed lint error — replaced nested ternary in sortValues cache slot selection with an if/else block to satisfy Biome's nursery/noNestedTernary rule (which is enabled as an error via nursery: { all: true })

Two pushes made:

• Push 1: rebase onto origin/main
• Push 2: fix nested ternary in src/core/series.ts line 784

CI should now pass on the new HEAD 15b21bb.

Evergreen: CI Fix ✅

Two pushes were made to this PR:

Push 1 — Rebase onto main (19 commits behind)
Rebased autoloop/tsb-perf-evolve onto origin/main cleanly with no conflicts.

Push 2 — Fix Biome lint errors

The failing Test & Lint check had these errors:

• lint/style/useBlockStatements in tests-e2e/playground-cells.test.ts and src/io/read_html.ts — added braces to single-statement if bodies
• lint/style/useSingleCaseStatement in tests/xval/runner.test.ts — collapsed replayScenarioX(); return; pairs into return replayScenarioX(); in the switch statement

CI is now running on the new HEAD (8655688).

Evergreen Fix

Push 1 — Rebase onto main: Rebased the branch onto main (19 commits behind), applying cleanly with no conflicts.

Push 2 — CI lint fix: Fixed a lint/style/useSingleCaseStatement error in tests/xval/runner.test.ts. Each switch case had two statements (function call + return); wrapped them in {} blocks to satisfy Biome's rule.

The noMisplacedAssertion warnings in tests/xval/helpers.ts are warnings only (not errors) and do not affect CI pass/fail.

CI has been triggered on the new HEAD 40bfc4d.

Two pushes were made to this PR:

1. Rebase onto main (19 commits behind): Clean rebase, no conflicts.

2. CI fix in src/core/series.ts:

   • Replaced nested ternary (ascending ? (... ? 0 : 1) : (... ? 2 : 3)) with an explicit if/else block to resolve Biome's noNestedTernary lint error.
   • Wrapped single-statement if return with braces (useBlockStatements).

Evergreen CI Fix 🌲

Two pushes were made to bring this PR up to date:

Push 1 — Rebase onto main (19 commits)

The branch was rebased onto main to resolve the drift.

Push 2 — Fix lint errors

The CI lint failure (biome check) had 3 errors:

1. src/core/series.ts — formatter drift (auto-formatted)
2. tests/io/read_html.test.ts (×2) — noUnnecessaryTemplateLiteral: changed backtick strings with no interpolation to regular strings

These are the only changes. All 672 warnings were pre-existing and unchanged.

Evergreen fix applied 🌿

Two pushes made to this PR:

1. Rebase onto main — brought the branch up to date with 19 commits from main.

2. Lint fix — replaced a nested ternary in sortValues with an if-else block to satisfy Biome's noNestedTernary rule (the single lint error from CI):

   // Before (error: noNestedTernary)
   const svSlot = ascending ? (naPosition === "last" ? 0 : 1) : (naPosition === "last" ? 2 : 3);
   
   // After
   let svSlot: 0 | 1 | 2 | 3;
   if (ascending) {
     svSlot = naPosition === "last" ? 0 : 1;
   } else {
     svSlot = naPosition === "last" ? 2 : 3;
   }

CI should now pass. The _svCache optimization (O(1) repeat sortValues calls) is preserved.
