The git2.h umbrella header does not pull in the sys/ headers, so git_allocator (used to bind libgit2 to mimalloc) was an unknown type under libgit2 1.9. Include git2/sys/alloc.h explicitly.
Classify each node in the layout and surface it in the graph UI so dead code is visible and filterable. Backend (layout3d.c): - Parse per-node flags (is_entry_point/is_test/is_exported/route_path) from properties_json and compute a `status`: dead | single | entry | test | exported | normal | structural. - Dead = Function/Method with zero incoming CALLS and zero USAGE that is not an entry point, route, test, or exported symbol. - Caller counts come from the full graph via cbm_store_batch_count_degrees, NOT the sampled render edges (which drop edges to off-screen nodes and would falsely mark sampled-in functions as uncalled). Batched in chunks of 500 to stay within the store's bound-IN-clause capacity. - Emit `status` and `in_calls` in the layout JSON. Frontend: - GraphNode gains status/in_calls; colors.ts adds a status palette + legend. - FilterPanel: "Dead code" section — color-by-status toggle, show-only-dead, hide-entry-points, hide-tests, and a live dead count. - GraphTab wires the filters and recolors nodes by status when enabled. Note: filters act on the rendered node sample (name-ordered, default 2000, cap via CBM_UI_MAX_RENDER_NODES) like all existing filters. Also gitignore the generated src/ui/embedded_assets.c build artifact.
Commit d9d7065 capped the graph render limit to 2000 nodes (hard max 10000). At that size almost every node has degree 0-1, so the stellar degree-coloring collapses to uniform red and nearly all edges are dropped (both endpoints must be in-sample), losing the connected overview. Restore the pre-cap limit: DEFAULT_MAX_NODES and HARD_MAX_NODES back to 50000 and the frontend GRAPH_RENDER_NODE_LIMIT to 50000. On samay this brings back the full 50,000-node / 120,755-edge view with varied stellar colors, and makes the dead-code classification meaningful (913 dead vs 0 in the tiny sample). Tune down at runtime via CBM_UI_MAX_RENDER_NODES.
… regex search Hovering/clicking a node now surfaces its code and location. Backend: - layout3d emits qualified_name, start_line, end_line per node. - New GET /api/repo-info?project= returns the indexed repo's git remote normalized to a web base + blob_base (https://host/org/repo/blob/<branch>), read via libgit2. Handles scp-style (git@host:org/repo.git), ssh:// and https:// remotes; empty fields when there is no remote. Frontend: - Hover tooltip enriched: file:lines, dead-code status + caller count. - NodeDetailPanel: file:line range, "Show code" (fetches the snippet via the existing /rpc get_code_snippet tool and renders it), and "Open on GitHub" deep-link to the exact lines. Code resets when the selected node changes. - GraphTab fetches repo-info per project and passes it + project to the panel. Sidebar fixes (reported): - Search is now a case-insensitive regex (matches name, file_path, qualified_name), falling back to literal substring on invalid regex, with an inline hint. Result cap raised 50 -> 500 with a "refine the search" notice. - Whole left sidebar scrolls as one region (overflow-y-auto); Sidebar gains an `inline` mode so the tree no longer nests its own scroll and the tall filter panel can't clip the search/tree.

Summary
Adds dead-code discovery and code navigation to the graph UI, plus a couple of sidebar fixes and a build fix.

Fixes
restore 50k node render limit— the prior 2000-node cap collapsed stellar degree-coloring to uniform red and dropped nearly all edges. Restored to 50000 (tunable viaCBM_UI_MAX_RENDER_NODES), which also makes dead-code classification meaningful.include git2/sys/alloc.h for git_allocator— thegit2.humbrella header does not pull insys/headers, breaking the build under libgit2 1.9.Verification
