From 434a94c7e1144e361e9cc450f9ebe4d67dc291fc Mon Sep 17 00:00:00 2001 From: Coding-Dev-Tools Date: Wed, 26 Aug 2026 05:23:48 -0400 Subject: [PATCH] fix(graph): route the four spacetime sliders into d3 forces in non-galaxy mode The Galactic gravity, Black hole mass, Local solar gravity, and Space damping sliders previously only fed the galaxy-mode integrator. In the default overview/communities/compact views a settled d3 layout had already cooled, so a force-only re-render was invisible and the user-facing effect of the sliders was "nothing happens when I drag it". This change wires each spacetime slider into the d3-force installation so the layout visibly responds in every non-galaxy mode: - gravitationalConstant (0..200) scales the charge (node repulsion) strength. Default 100 -> 1.0x; max 200 -> 2.0x; min 0 -> 0x. - blackHoleMass (0..500) scales the existing gravity-driven centering strength via the same multiplier used by the galaxy-mode integrator (linear above the 160 baseline, value/160 below). Default 160 -> 1.0x; 500 -> 7.8x; 80 -> 0.5x. - localGravitationalConstant (0..200) scales the link spring strength. The existing d3 path used 1/(min degree) as the base; we now multiply by the same scalar so the slider tightens or loosens the visible link force. - damping (1..15) maps to fg.velocityDecay. At 1 the layout is bouncy (decay 0.05); at 15 it settles quickly (decay 0.85). Bounded 0.05..0.85 so the extreme ends stay usable. Two small helpers (clamp, blackHoleMassMultiplier) are inlined next to the d3-force install path; the existing helper in ledger.js is unchanged. A new regression test test_spacetime_sliders_reach_d3_forces_in_non_galaxy_mode instruments fg.d3Force / fg.velocityDecay to confirm each spacetime setting lands on the d3 wire. Fixes the user-reported "Galactic gravity / Black hole mass / Local solar gravity / Space damping sliders STILL NOT WORKING CORRECTLY" complaint. --- engraphis/dashboard_assets/engraphis-graph.js | 49 ++++++++++-- tests/test_graph_engine_asset.py | 74 +++++++++++++++++++ 2 files changed, 117 insertions(+), 6 deletions(-) diff --git a/engraphis/dashboard_assets/engraphis-graph.js b/engraphis/dashboard_assets/engraphis-graph.js index 62bb3333..087a313a 100644 --- a/engraphis/dashboard_assets/engraphis-graph.js +++ b/engraphis/dashboard_assets/engraphis-graph.js @@ -613,6 +613,25 @@ const MAX_AUTO_FIT_ZOOM = 4; const SETTINGS_ALPHA_TARGET = 0.12; const ALPHA_TARGET_HOLD_MS = 180; + /* Inline utility: bound a value to [min, max].
