…ort, key lookup severity (#65) - Batch mode sort skew: downgrade to Info with "by design" note (unless feeding Window Aggregate) - Root node tooltip now includes statement-level PlanWarnings (e.g., Optimize For Unknown) - OPTIMIZE FOR UNKNOWN: distinguish from OPTION(RECOMPILE) in parameter annotations - Key Lookup with predicate: upgrade from Warning to Critical - Table variable: add statement-level warnings for stats + modification serial execution (Critical) - Top N Sort: parse <TopSort> XML element, set LogicalOp to "Top N Sort" - Rule 24: broaden to any Top/Top N Sort above scan (Critical when on NL inner side) - Fix IsOrExpansionChain to match normalized "Top N Sort" LogicalOp - Update Rule 22 test for new statement-level warnings Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
…P-aware parallelism rules (#66) - Edge connector tooltips now match SSMS with all 5 fields (actual rows, estimated per-execution, estimated all-executions, row size, data size) - Right-click context menu on plan canvas (zoom, advice, repro, save) - Fixed context menu to use ScrollViewer (Canvas has no hit-test background) - Merge joins always show Many to Many: Yes/No in tooltip - LayoutTransformControl for proper zoom+scroll behavior - Fit zoom scrolls to origin so plan root is immediately visible - Rules 25/31 now use DOP-aware efficiency scoring: efficiency = (CPU/Elapsed - 1) / (DOP - 1) * 100 instead of simple CPU/Elapsed ratio Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
…#70) * Operator grouping, margin standardization, and elapsed time visibility - Group operator name + timing + CPU bar + stats (rows/reads) in a single container with purple left accent border for clear visual association (#14) - Standardize left margins to three tiers: 8px labels, 12px content, 20px nested detail — eliminates ragged left edge (#15) - Use ValueBrush for both CPU and elapsed timing values instead of dimming elapsed with MutedBrush (#16) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Add proportional bars to wait stats in Advice for Humans Collect all wait stat lines in a group, find the global max, then render each with a colored bar scaled proportionally. Bar color matches wait category (orange=CPU/parallelism, red=I/O/locks, purple=memory, blue=network). Closes #48 item 7. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Triage card headline hierarchy — first item 13px semi-bold The most significant finding in each triage card (parallel efficiency, memory grant, etc.) now renders at 13px semi-bold to establish visual hierarchy over the remaining 12px normal-weight items. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Color-code missing index impact percentage by severity Impact line (e.g., "dbo.Posts (impact: 95%)") now renders table name in white and impact in color: red ≥70%, amber ≥40%, blue <40%. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Memory grant contextual color in triage card Color by utilization: red <10% used, amber 10-49%, blue ≥50%. Previously was binary amber/blue at 10% threshold. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
Builds dev branch daily at 6AM UTC for all 4 platforms (win-x64, linux-x64, osx-x64, osx-arm64) with macOS .app bundling. Skips if no commits in last 24 hours. Creates rolling "nightly" prerelease tag with checksums. Can also be triggered manually. Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
Thread analysis data to ShowAdviceWindow so triage cards and other structured features have access to parsed statement results. Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
Filter out thread 0 (coordinator) from skew calculation since it typically processes 0 rows in parallel operators, inflating the thread count. Raise the DOP 2 threshold from 75% to 80% — a 53/47 split is perfectly normal with only 2 worker threads. Fixes #73. Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
- New AppSettingsService persists recent plans (last 10) and open session state to JSON in %LOCALAPPDATA%/PerformanceStudio/appsettings.json - File > Recent Plans submenu with clear option; gracefully handles moved/deleted files by removing them and notifying the user - On close, saves all open file-based plan tab paths; on next launch, restores them (falls back to a fresh query tab if none restored) - Only file-based plans are tracked (not clipboard paste or Query Store) Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
Add FormatMemoryGrantKB helper to TextFormatter that picks the most readable unit: KB under 1024, MB with 1 decimal up to 1 GB, GB with 2 decimals above. Applied in both the text output and the runtime summary pane. Closes #68 Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
