q2 graph notebook: cockpit frontend + Rust binary#1
Merged
Conversation
Two design variants for the cockpit UI: - cockpit.css/js + index.html: Pure CSS Grid layout with custom force-directed graph simulation, sortable linked table, properties sidebar, notebook cell stack. Dark theme (#0a0e17), teal accents (#00bcd4), Inter + JetBrains Mono. - cockpit-tailwind.html: Tailwind-based single-file variant with 3-column layout (notebook sidebar, graph+table center, inspector right). Both implement: query bar with language auto-detection, interactive draggable graph nodes, linked selection (graph <-> table <-> properties), syntax- highlighted code cells (Gremlin/R/SPARQL), mini chart output, status bar. https://claude.ai/code/session_01LSbSrej6WdKum1zCxEHE8z

Third design variant with 4-row, 3-column CSS Grid layout: situation panel (metrics, filters, example queries), center graph with force sim + panning/zoom, node intelligence sidebar with sparkline canvas, full-width result table, reactive cell strip. https://claude.ai/code/session_01LSbSrej6WdKum1zCxEHE8z
The q2 binary now includes `q2 notebook serve` and `q2 notebook render`:
Server (port 2718):
- GET / → cockpit frontend (placeholder)
- GET /health → {"status":"ok","engine":"lance-graph"}
- GET /mcp/sse → MCP over Server-Sent Events
- POST /mcp/message → MCP tool invocations (JSON-RPC 2.0)
MCP tools: cell_execute, cell_get, cells_list, cell_create,
cell_update, cell_delete, dag_get, notebook_save, notebook_load,
notebook_export
Language auto-detection:
- g.V() → gremlin, MATCH ( → cypher, PREFIX/SELECT ? → sparql
- %>%/<- → r, let/fn → rust, else → markdown
Publisher:
- q2 notebook render input.nb --format html → self-contained HTML
with dark cockpit theme, collapsible code cells, embedded tables
- q2 notebook render input.nb --format pdf → shells out to pandoc
Stub crates (6): notebook-runtime, notebook-query, notebook-kernel,
notebook-render, lance-graph, q2-ndarray. Each marked TODO for
replacement when real crates are transcoded.

Replace the Phase 0 unimplemented!() bodies with the real impls: AttributionDataBuilder interns actors once and Arc::clone-s thereafter; AttributionMap::query_byte_range uses partition_point + a forward walk to pick the most-recent overlapping run; PreBuiltAttributionProvider:: build re-interns through the builder so transport JSON round-trips restore Arc<str> ptr-equality; format_supports_attribution matches FormatIdentifier::Html (covers html, q2-debug, extension HTML); from_config_value reads meta.attribution.identities into an IdentityMap with fresh Arc keys so Phase 2's merge can preserve provider keys on collision. Turns Phase 0 tests #1 + #2 (10 cases) green; the 8 regression pins stay green.

The frontier-map's highest-leverage [G] probe (Dudzik-Veličković, GNNs are Dynamic Programmers, 2203.15544: message-passing = DP over a semiring), made executable. The diplotype→phenotype→recommendation chain `cpic reason` computes is a single semiring transitive closure (Floyd-Warshall) over the CPIC edge adjacency; swapping ONLY the semiring switches the reasoning mode on the SAME graph: Boolean→reachability, MinPlus→cheapest path, Nars→CPIC confidence (f=f1f2, c=f1f2c1c2), MaxTimes→most-likely path. Keystone (asserted + unit-tested): the Nars semiring closure reproduces reason.rs's deduction EXACTLY for CYP2C19 *2/*2 → clopidogrel — f=0.950, c=0.767, identical. Retrieval and reasoning are the same operation; the mode is the algebra, not the traversal. Edge truths read from the real CPIC recommendation classification + pair cpiclevel (same mapping as reason.rs). Self-contained Floyd-Warshall keeps cpic dep-light; in production this is a lance-graph GraphBLAS matrix walk at scale. 2 tests (the keystone identity + four-modes-one-graph). POC over published CPIC rules — NOT clinical decision support. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GJ4NVBSjq1w5h7RmTbVafb
