Replaced complex dashboard with minimal search.html: - No external JS/CSS files, no transpilation, no module imports - Plain JS with .then() chains (no async/await compat issues) - DOM-only rendering via createElement (no innerHTML with data) - 20s AbortController timeout so fetch never hangs - Detects /lakehouse/ proxy prefix automatically - 7KB total, loads in 18ms Calls lakehouse /vectors/hybrid directly — SQL filters always apply, works even when HNSW isn't loaded (brute-force fallback).

|
||
* Lakehouse MCP Server — bridges local LLMs to the data substrate.
|
||
*
|
||
* Tools:
|
||
* - search_workers: hybrid SQL+vector (the core fix)
|
||
* - query_sql: analytical SQL on any dataset
|
||
* - match_contract: find workers for a job order
|
||
* - get_worker: single worker by ID
|
||
* - rag_question: full RAG pipeline
|
||
* - log_success: record what worked → playbook DB
|
||
* - get_playbooks: retrieve past successes
|
||
* - swap_profile: hot-swap model + data context
|
||
* - vram_status: GPU introspection
