 | 2026-10-10 | minor | M9 row from main: initial Revolve |
 | 2026-10-10 | minor | Added the Alpha gate table (core-workflow gate): all six workflows work end to end, `.ai` exchange partial but not blocking; stage stays alpha |
 | 2026-10-10 | major | Created from ROADMAP.md's milestone table and "Where we're going"; added Current focus and the beta list |
+| 2026-10-28 | minor | Flare ray rotation follows vertical travel at one degree per document point, independent of pointer event count. Shift freezes the current orientation; Space also freezes rotation on the first update. This is the chosen application interaction rate. Scores and estimates unchanged. |
 | 2026-10-28 | minor | Drop Shadow Darkness subtracts the normalized amount from RGB source channels or adds it to CMYK/Gray black before profile conversion and blur; near-100% becomes gray black, with shadow opacity separate. SVG keeps live filters for uniform sRGB sources and renders shadows for other RGB profiles, source models and gradients. Gradient-stop adjustment is an application rule; spot/custom colors and composite-source parity remain open. Scores and estimates unchanged. |
 | 2026-10-28 | minor | Blob Brush Shift locks after clear axial movement, keeps earlier samples fixed, and waits without an off-axis trail. Activation uses raw press displacement in logical screen pixels, with exact quarter-turn boundaries. Explicit application rule; scores and estimates unchanged. |
 | 2026-10-28 | minor | Flare Tool Options opened by a canvas click previews its settings at that click. Reset refreshes the enabled preview while keeping the dialog open. Cancel discards preview art and tentative options; OK accepts one flare in one Undo step. Editing existing flare artwork remains outside this dialog scope. Scores and estimates unchanged. |
