- Neuron pair programming panel (right column, 300px): full conversation interface
with code-block rendering, "Insert at cursor" for AI suggestions, quick actions
(explain selection, find activations, analyze types), thinking indicator
- Live activation preview: floating inline widget when cursor is inside
`activate TypeName where "..."` expressions; queries /api/lsp/activate-preview
- Type graph activation highlighting: `activate` statements cause named types to
pulse with purple glow rings; animation loop runs while activations are present
- Knowledge Graph Explorer: new bottom panel tab; search the Engram DB for semantic
concepts, insert activate expressions, ask Neuron about nodes
- Semantic autocomplete: completions with score >= 0.8 get "⟁ semantic" prefix and
priority boost in the completion list
- Backend: /api/reason extended to support three modes: "hypothesis" (existing),
"pair" (proxies to soma /v1/chat/completions with full file context + system
prompt), "knowledge-search" (proxies to Engram DB search endpoint)
- Backend: new GET /api/lsp/activate-preview endpoint queries Engram for nodes
matching a partial activate expression
- Type graph node click now navigates editor to the type definition
- Resolved merge conflicts in engram-lang/crates (ast.rs, parser.rs, checker.rs,
types.rs): took union of HEAD and worktree-agent branches
Axum HTTP server (port 7771) serving a single-page IDE with CodeMirror 6
syntax highlighting for engram-lang, a force-directed type graph visualizer,
LSP (completions, hover, diagnostics), SSE-streamed build/run output, a
plugin host with five first-party plugins, and a reasoning panel that proxies
to engram-server. 28 tests across three crates, zero warnings.
