Merge dev to main: web plan analysis (v1.5.0)
Click any plan tree node to open a right-side properties panel with full operator details. Matches desktop app parity across all 37 sections including per-thread stats, predicates, costs, memory, and root-only statement info. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Web: Add operator properties panel (#176)
The plan XML's MemoryGrantWarning element fires for any grant size, including trivially small ones (1 MB). Gate at 1 GB to suppress noise, consistent with the analyzer's Rule 9 threshold. All values confirmed as KB across all example plans. Updated test to verify small grants are suppressed. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Gate XML MemoryGrantWarning at 1 GB threshold
- Rule 3 (Serial Plan): Skip trivial statements with cost < 0.01 — a 0ms variable assignment shouldn't warn about MAXDOP 1 - Rule 15 (Join OR Clause): Exclude Merge Interval patterns inside anti/semi joins — NOT IN subqueries produce the same operator chain but aren't OR expansions - Rule 26 (Row Goal): Require >= 2x reduction — "1 to 1 (1x reduction)" and tiny floating-point differences are noise Tests load from .internal/examples (gitignored) and skip gracefully on CI. Closes items 5, 9, 12 from #178. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Rule 1 (Filter Operator): Suppress when child subtree is trivial — actual plans: < 128 reads AND < 10ms; estimated plans: cost < 1.0 - Rule 20 (Local Variables): Gate on statement cost >= 0.01 to skip trivial variable assignments where estimate quality doesn't matter Both fixes work correctly for estimated and actual plans, using cost-based fallbacks when runtime stats aren't available. Closes items 6, 7, 11 from #178. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Rule 4/6 (Scalar UDF): Expanded remediation options — mention assigning to a variable, SQL Server 2019+ automatic UDF inlining - Warning badge: Split count by severity (critical/warning/info) with color-coded badges instead of a single combined number - Statement tabs: Show elapsed time instead of cost for actual plans - Wait stats: Wider wait type column (180px) and double-width card when populated for better readability Closes items 2, 3 (partial), 4, 10 from #178. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Statement tabs sorted by elapsed time (actual plans) or cost (estimated plans), slowest first — problem statement is always immediately visible - Replaced small PNG logo with full Darling Data barbell logo from erikdarling.com, bumped height to 40px for legibility - Default active statement is the first tab (sorted, so the slowest) Closes items 1, 3 from #178.

- Rule 3 (Serial Plan): Suppress for TRIVIAL plans and 0ms actual elapsed; demote to Info unless user explicitly forced serial (MAXDOP 1 / hint) - Statement tab warning count: Use total (statement + node) warnings to match the main warnings strip count - Parameters card: Span 2 columns when populated for more horizontal space Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
