Search VHDL source: entities, architectures, processes, packages, functions — semantic + exact-identifier hybrid search. symbols restricts to chunks referencing the given identifiers (e.g. ["fifo_write", "rst_n"]). category: golden/approved/ project/legacy. repository restricts to one repository name.

Search VHDL-related documentation: coding standards, design guides, conventions (one result per section). symbols matches identifiers referenced in the section's code snippets.

Search general source code (C/C++, Python, ...): one result per function/class. symbols matches identifiers referenced in the unit (cross-reference to VHDL signal/port names, etc.).

Search ALL domains (VHDL, documentation, code) at once, fused with RRF so the domains interleave fairly. Use when the question may span domains (e.g. a design requirement in the docs implemented in VHDL and tested in C).

Read the exact current content of an indexed file (or a line range) from the synced repository, with commit attribution. file is the repository-relative path from any search result's source line.

Show every configured repository: category, ref, enabled domains, last indexed commit, last sync time, and any sync error.

Incrementally sync repositories (default: all): fetch the ref, chunk changed files, update the index. Safe to call any time; failures are contained per repository and reported.

Fully reindex one repository (drops and rebuilds all of its chunks). Use after config changes or to repair a drifted index.
