Live concept map click any viz to explore
These are real bellamem self-graph renders — the graph the tool built of its own development conversation, filtered to concepts with mass ≥ 0.7 (the ratified structural spine). Click a node for detail; drag, zoom, and explore. Same underlying graph, three different renderers.
3D concept map
Topic embeddings cluster semantically along X/Z. Mass lifts ratified content above the floor plane. Shape encodes class, color encodes nature. Click any mesh for the full concept detail.
2D force-directed
d3-force physics with draggable nodes. Grab any concept and pull it to untangle dense clusters. Edge labels show cause / elaborate / dispute relationships.
2D cytoscape
fcose force-directed with auto-settling layout, smooth animations, and built-in wheel zoom. Cleaner default layout than D3 at the cost of live drag.
--min-mass 0.7
with turn hubs disabled. Only the ratified structural spine is visible —
low-mass ephemerals and turn-preview text are excluded so nothing about
this project's internal conversations leaks beyond concept topics.
The ontology every concept on two orthogonal axes
The ontology isn't decorative. It drives retrieval, decay, and dispute handling. A normative decision about testing style doesn't decay the way an ephemeral observation about yesterday's build does.
class — where does it come from, how is it used
invariant
time-stable principles and structural facts about the system
decision
commitments that constrain future action ("ship X before Y")
observation
a single empirical record about current state
ephemeral
pinned plans with an explicit state machine and decay
nature — what kind of claim is this
metaphysical
self-model, architectural facts, load-bearing invariants
normative
rules, preferences, policies, code conventions
factual
checkable facts about the world, benchmark results
