I — Symbol indexer

Tree-sitter-backed symbol index. Enables senkani_search, senkani_fetch, senkani_outline, senkani_deps, senkani_explore.

What it does

Extracts symbols from source files via 25 vendored tree-sitter grammars; keeps the index in memory; updates incrementally via FSEvents; persists BM25 + FTS5 search index. Cold search < 5 ms, cached < 1 ms.

Env var

SENKANI_INDEXER=on|off — default on. Off disables symbol tools for the pane; agents fall back to text-grep (expensive).
