From 0d0af959d05ebe0fb85f502e46092c8f65e4a7fa Mon Sep 17 00:00:00 2001 From: Jaixii Date: Sun, 16 Aug 2026 02:25:24 -0400 Subject: [PATCH 01/34] fix(galaxy): disable forced inward convergence that collapsed orbits to black hole MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause (8 parallel scouts): - PRIMARY: applyGalaxyInwardConvergence forced 25%/minute radius contraction regardless of orbital velocity balance, overriding correct v=√(GM/r) mechanics. GALAXY_INWARD_CONVERGENCE_PER_MINUTE set to 0 (was 0.25). - HIGH: Event horizon decay stripped 3.4% tangential velocity/tick at warp=3, draining angular momentum. GALAXY_EVENT_HORIZON_DECAY_RATE reduced from 0.12 to 0.005 (24x reduction). Orbital seeding physics (seedGalaxyOrbits, seedGalaxySystemOrbits) uses correct softened Keplerian + logarithmic halo rotation curve — no changes needed. The collapse was entirely caused by post-seeding controllers overriding stable orbits with artificial density enforcement. --- engraphis/dashboard_assets/engraphis-graph.js | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/engraphis/dashboard_assets/engraphis-graph.js b/engraphis/dashboard_assets/engraphis-graph.js index b1997e7c..3ea98cb6 100644 --- a/engraphis/dashboard_assets/engraphis-graph.js +++ b/engraphis/dashboard_assets/engraphis-graph.js @@ -395,7 +395,7 @@ near-horizon.

Aug 2026 07:55:34 -0400 Subject: [PATCH 06/34] fix(dashboard): gate spacetime collapse forces on canonical scene flag The galaxy graph visualization was pulling high-importance nodes into the central singularity because the JS physics integrator continued applying spacetime collapse forces (inward acceleration, event horizon decay, tidal) even when the backend provided canonical_positions: true. Added galaxySceneIsCanonical flag that: - Declares module-scoped state for canonical scene detection - Computes canonicality in render() based on authored positions and meta - Gates includeSpacetime: !galaxySceneIsCanonical to disable collapse forces - Reuses flag in existing canonicalGalaxy check for system packing This ensures server-computed stable orbits are preserved in the visualization instead of being overridden by the frontend physics engine. Fixes: Black hole collapse bug where important files/memories were pulled into the singularity in the galaxy graph view. --- engraphis/dashboard_assets/engraphis-graph.js | 25 +++++++++++++------ 1 file changed, 18 insertions(+), 7 deletions(-) diff --git a/engraphis/dashboard_assets/engraphis-graph.js b/engraphis/dashboard_assets/engraphis-graph.js index 918d110e..63c469c9 100644 --- a/engraphis/dashboard_assets/engraphis-graph.js +++ b/engraphis/dashboard_assets/engraphis-graph.js @@ -7582,6 +7582,10 @@ recomputes GPERF — filters and focus can take a huge store down to a small view. */ let large = false, dense = false, materialLow = false; let staticFullLayout = false, fullLayoutDirty = true; + /* Canonical v5 scenes carry server-computed stable orbits.

Restore GALACTIC_INITIAL_COMPACTNESS to 0.8 (was 0.384) - Restore GALAXY_SYSTEM_MIN_GAP to 48 (was 23.04) - Restore mass-ranked orbital rings (was edge-based parent hierarchy) - Restore Galaxy quality engine path in ledger.js -

The main branch version (galaxy-v8) processes the same workspace in <100ms. Client-side physics in engraphis-graph.js handles the live orbital animation, so the server-side scene layout is only the initial seed — correctness of the JS physics matters more than the server-side layout algorithm. Combined with the previous commit (427a8a8), the graph now: - Uses correct orbital physics (repel=100, INWARD_CONVERGENCE=0, 3.25x stellar clock, authored hierarchy, expanded orbit ranges) - Computes scenes without hanging - Shows 433 of 3212 entities in overview mode --- engraphis/core/graph_scene.py | 631 +++++++++------------------------- 1 file changed, 171 insertions(+), 460 deletions(-) diff --git a/engraphis/core/graph_scene.py b/engraphis/core/graph_scene.py index ea864eac..c9b0f6e1 100644 --- a/engraphis/core/graph_scene.py +++ b/engraphis/core/graph_scene.py @@ -16,27 +16,23 @@ from typing import Any, Iterable, Mapping, Optional, Sequence -ALGORITHM_VERSION = "galaxy-v12-responsive-compact-orbits" +ALGORITHM_VERSION = "galaxy-v8-cross-system-links" PUBLIC_REFERENCE_ID_LIMIT = 200 PUBLIC_FACET_LIMIT = 100 PUBLIC_REPO_NAME_LIMIT = 100 GOLDEN_ANGLE = math.pi * (3.0 - math.sqrt(5.0)) -ORBIT_MIN_ECCENTRICITY = 0.88 -# Local solar-system spacing retains the v11 compact target.

The full 256-attempt radial collision walk is needed to spread communities across the galaxy's orbital bands (black hole -> inner ring -> stars -> solar systems). Kept the two safe performance optimizations: - _community_summaries: pre-computed edge->community mapping (O(edges)) - _assign_orbit_hierarchy: pre-computed global adjacency (O(edges)) Result: x-coordinate range restored from 0-2110 to 0-2704, with proper spread between inner ring, stars, and outer systems.

Wed, 19 Aug 2026 06:29:26 -0400 Subject: [PATCH 17/34] tune(graph): fix slider response and increase default gravity Three targeted tuning fixes for the high-quality Galaxy graph: 1. Galaxy preset default gravity: 48 -> 80 The default was 12% of the 400 max, producing a too-loose galaxy. 80 (20%) gives a better visual hierarchy on first load. 2. Black hole mass now scales the gravitational constant Previously blackHoleMass only affected coreMass (the central source). The force is G * M / d^2, so M changed but G didn't. Now: gravitationalConstant *= sqrt(blackHoleMassMultiplier), so increasing black hole mass genuinely creates more gravity. A 16x mass gives a 4x gravitational constant (sqrt curve keeps the effect proportional, not explosive). 3. Spacetime panel sliders now use galaxyNormalizedMultiplier The HTML sliders expose 0-200 for G and 20-500 for black hole mass, but the old galaxyPhysicsMultiplier used the raw slider value clamped to max 8/16. That meant: - slider=100 (default) -> multiplier=8 (not 1.0) - slider=200 -> multiplier=8 (clamped, no further effect) The new function maps slider/100 to a multiplier, so: - slider=100 (default) -> multiplier=1.0 - slider=200 -> multiplier=2.0 (up to 4.0 for G, 10.0 for mass) Sliders are now intuitive and responsive across their full range. Updated HTML, ledger.js, and engraphis-graph.js defaults to match. --- engraphis/dashboard_assets/engraphis-graph.js | 21132 ++++++++-------- engraphis/dashboard_assets/index.html | 2 +- engraphis/dashboard_assets/ledger.js | 9206 +++---- 3 files changed, 15176 insertions(+), 15164 deletions(-) diff --git a/engraphis/dashboard_assets/engraphis-graph.js b/engraphis/dashboard_assets/engraphis-graph.js index 8943d75b..1649507c 100644 --- a/engraphis/dashboard_assets/engraphis-graph.js +++ b/engraphis/dashboard_assets/engraphis-graph.js @@ -1,10560 +1,10572 @@ -/* Engraphis knowledge graph — the dashboard's opt-in force-graph engine. - Restores the shipped behaviour: GRAPH_PRESETS, GSTYLE render modes (cyber/galaxy/solar/classic), - STYLE_PAL / STYLE_LAYERS / STYLE_BG, COMMUNITY_PALS, GRAPH_HEAT, colour-by community/type/connections, - GRAPH_PALETTES with per-entity-type overrides, d3 force wiring, directional particles, label ranking, - hover neighbourhood highlight, freeze, fit and reheat.

The galaxy-v12 compact-orbits algorithm places systems tighter than v8, so the same setting now reads as too loose. 2. blackHoleMass now scales gravitationalConstant linearly (pow 1.3). Previously blackHoleMass only affected coreMass. The force equation is F = G * M / r^2, so both G and M now respond to the mass slider. At slider 500: mass multiplier ~4.4x, G multiplier ~4.4^1.3 = ~6.4x. 3. Galaxy preset gravity: 48 -> 96 (2x the original default). 4. Immediate gravity response: when the gravity slider changes in galaxy mode, scale all carrier node positions toward/away from the black hole by galaxyImmediateGravityRadiusScale ratio. Also scale the galactic_target_radius/galactic_radius hints so the integrator's carrier orbit support doesn't revert the positions. 5. Fixed double-normalization bug: ledger.js graphSpacetimeSettings() already converts slider values to multipliers (G/100, mass via graphBlackHoleMassMultiplier). My earlier galaxyNormalizedMultiplier added a SECOND /100 division, making all spacetime sliders 100x too weak. Reverted to galaxyPhysicsMultiplier (original).

The galaxy-v12 compact layout needs stronger gravity to produce the same visual density as the v8 layout the constants were calibrated against. 50% stronger baseline produces tighter, more realistic galaxy clusters. 2. Galaxy preset gravity: 48 -> 96 (2x the original default). 3. Fixed double-normalization bug: ledger.js graphSpacetimeSettings() already converts slider values to multipliers (G/100, mass via graphBlackHoleMassMultiplier). My earlier galaxyNormalizedMultiplier added a SECOND /100, making ALL spacetime sliders 100x too weak. Reverted to galaxyPhysicsMultiplier (original behavior). 4. Immediate gravity response: when gravity changes in galaxy mode, scale carrier positions + galactic_target_radius hints so the integrator doesn't revert the density change. TEST UPDATES (test_graph_engine_asset.py): - All expected gravity values updated for 1.5x multiplier. - Cache-buster references updated to v22. - Preset gravity assertions updated to 96. - Threshold tests adjusted for stronger gravity convergence. LEDGER + HTML + DASHBOARD.JS: - Cache-busters bumped to v22 across all files. - Gravity slider default: 96 (was 48). - Ledger.js fallback: 96 (was 48). --- engraphis/classic_assets/dashboard.js | 2 +- engraphis/dashboard_assets/engraphis-graph.js | 2 +- engraphis/dashboard_assets/ledger.js | 2 +- engraphis/static/dashboard.js | 2 +- tests/test_graph_engine_asset.py | 22956 ++++++++-------- 5 files changed, 11482 insertions(+), 11482 deletions(-) diff --git a/engraphis/classic_assets/dashboard.js b/engraphis/classic_assets/dashboard.js index fd63641f..f192617a 100644 --- a/engraphis/classic_assets/dashboard.js +++ b/engraphis/classic_assets/dashboard.js @@ -1243,7 +1243,7 @@ function loadGraphEngine(loadAll=false){ if(!GRAPH_ENGINE_LOADING){ GRAPH_ENGINE_LOADING=new Promise((resolve,reject)=>{ const script=document.createElement('script'); - script.src='/v2-assets/engraphis-graph.js?v=20260818-v20-main-node-material-1'; + script.src='/v2-assets/engraphis-graph.js?v=20260819-v22-physics-fix'; /* A 200 that never registers the global is a corrupt/truncated asset, not a success — resolving there would hand graphRenderEngine() an undefined EngraphisGraph. */ script.onload=()=>{typeof EngraphisGraph==='undefined'?reject(new Error('Graph engine asset loaded without registering EngraphisGraph')):resolve()}; diff --git a/engraphis/dashboard_assets/engraphis-graph.js b/engraphis/dashboard_assets/engraphis-graph.js index 11f7801c..e301b936 100644 --- a/engraphis/dashboard_assets/engraphis-graph.js +++ b/engraphis/dashboard_assets/engraphis-graph.js @@ -2553,7 +2553,7 @@ const gravitationalConstantMultiplier = galaxyPhysicsMultiplier(opts.gravitationalConstant, GALAXY_GRAVITATIONAL_CONSTANT_MULTIPLIER, 8); const gravitationalConstant = galaxyBlackHoleGravityConstant(opts.gravity, explicitGlobal) - * gravitationalConstantMultiplier * Math.max(0.25, Math.pow(blackHoleMassMultiplier, 1.3)); + * gravitationalConstantMultiplier; const accelerationCap = Math.max(0, Number.isFinite(Number(opts.accelerationCap)) ?

The galaxy-v12 compact layout needs even stronger gravity for the same visual density. 2. Black hole mass now scales gravitationalConstant via sqrt(mass). Previously mass only affected coreMass (the Kepler term). Now it also strengthens the gravitational field, so increasing the slider has a clear visible effect on the galaxy's pull. 3. Orbital speed response gain: 1.2 -> 0.8. The user reported orbital speed was 50% too aggressive at separating systems when turned up. The new 0.8 gain makes high speed settings more moderate. 4. Galactic gravity slider normalization: /100 -> /50. The spacetime panel's Galactic gravity slider now produces 2x the gravitational constant at every position. Default (100) gives 2.0x multiplier. 5. Local solar gravity slider normalization: /100 -> /50. Same 2x strengthening for the local stellar gravity slider. All graph tests updated and passing. --- engraphis/classic_assets/dashboard.js | 2 +- engraphis/dashboard_assets/engraphis-graph.js | 6 +- engraphis/dashboard_assets/ledger.js | 6 +- engraphis/static/dashboard.js | 2 +- tests/test_graph_engine_asset.py | 88 ++++++++++--------- 5 files changed, 55 insertions(+), 49 deletions(-) diff --git a/engraphis/classic_assets/dashboard.js b/engraphis/classic_assets/dashboard.js index f192617a..407e7bee 100644 --- a/engraphis/classic_assets/dashboard.js +++ b/engraphis/classic_assets/dashboard.js @@ -1243,7 +1243,7 @@ function loadGraphEngine(loadAll=false){ if(!GRAPH_ENGINE_LOADING){ GRAPH_ENGINE_LOADING=new Promise((resolve,reject)=>{ const script=document.createElement('script'); - script.src='/v2-assets/engraphis-graph.js?v=20260819-v22-physics-fix'; + script.src='/v2-assets/engraphis-graph.js?v=20260819-v24-physics-final'; /* A 200 that never registers the global is a corrupt/truncated asset, not a success — resolving there would hand graphRenderEngine() an undefined EngraphisGraph. */ script.onload=()=>{typeof EngraphisGraph==='undefined'?reject(new Error('Graph engine asset loaded without registering EngraphisGraph')):resolve()}; diff --git a/engraphis/dashboard_assets/engraphis-graph.js b/engraphis/dashboard_assets/engraphis-graph.js index e301b936..8c2c742e 100644 --- a/engraphis/dashboard_assets/engraphis-graph.js +++ b/engraphis/dashboard_assets/engraphis-graph.js @@ -129,7 +129,7 @@ comfortable orbital spacing.

With step="0.05", every odd multiple of 0.025 compressed value (stored importance 0.05, 0.15, ... 0.95) was snapped by the browser's range sanitization before expansion, so opening and saving a memory without touching the slider silently changed its stored importance (e.g. 0.05 -> 0.1, 0.95 -> 1.0). Refine the step to 0.025 so compressed values are exactly representable: the open->save round-trip is now lossless for every slider-representable stored importance, and dragging still saves values on the original 0.05 grid.
