Cross-session knowledge for DeepSeek Harness: ctx.knowledge service + knowledge_* tools, SQLite FTS5 trigram retrieval (CJK substring) with L1 query expansion. V1.11 contract (write/update/search/list/delete + budget + events + error codes).

经 MCP stdio 把 Agent 接入持久化 OKF 记忆库：Python 服务端（SQLite FTS5 + Markdown），10 个工具用于检索与写入决策、事实和偏好。

Turns attached files into versioned evidence: `search_documents` builds a private local index (SQLite FTS5 after a startup capability probe, dependency-free JS fallback otherwise) and returns compact evidence blocks carrying an exact coordinate — PDF page, PPTX slide, text/DOCX line range, or quoted XLSX `Sheet!Range` — which `read_document` expands only while the content version still matches. Contiguous CJK runs are indexed as overlapping bigrams and queried as phrases, so word order is preserved; uploaded raster images take the native vision attachment path instead.

DSH 记忆插件：全局热记忆自动常驻注入，经验库按需检索（本地 SQLite + FTS5），支持记忆审批与后台子代理定期提炼偏好决策。
