Adolf memory: migrate Cognee -> Hindsight + Kimi quota tooling
Memory migration (H1-H5, kb#73-77,84): - hindsight service in openai/docker-compose.yml: LLM via Kimi (cognee-llm wrapper), multilingual GPU embeddings (bge-m3 via ollama), jina multilingual reranker; pg0 + model cache persisted - openclaw.json/shared-mcp.json: mcp.servers cognee -> hindsight (bank "adolf") - hindsight-openclaw-plugin: forced-hook memory (before_prompt_build recall + agent_end retain), replacing cognee's hook layer; cognify-sweep dropped - verified live: Russian retain->recall, cross-session recall, bank isolation Kimi quota (kb#62): - adolf-llm/server.js: LLM-free GET /usage route (Kimi managed-usage API) - quota-command-openclaw-plugin: /quota readout command Cognee stack left running (decommission is H4/kb#76). Kimi-quota-footer auto-append abandoned (streamed Matrix replies bypass outbound hooks).

/**
|
||||
* Hindsight Memory — an OpenClaw memory plugin, structural successor to
|
||||
* cognee-openclaw-plugin (kb #75, H3). Same three touchpoints as the Cognee
|
||||
* plugin it replaces:
|
||||
*
|
||||
* before_prompt_build -> recall => LLM-free retrieval, injected as prependContext
|
||||
* agent_end -> retain => async persist of the turn (extraction runs server-side)
|
||||
* *_recall / *_reflect tool => on-demand recall (LLM-free) / reflect (LLM-synthesized)
|
||||
*
|
||||
* Why recall is LLM-free (verified against the live service, kb #75 H3):
|
||||
* POST /v1/default/banks/{bank}/memories/recall does semantic + BM25 (keyword)
|
||||
* + spreading-activation graph traversal + temporal scoring and returns ranked
|
||||
* raw fact/observation text (RecallResult.text) directly — there is no
|
||||
* generation step on this path. (Verified via a live probe against a
|
||||
* throwaway bank: POST retain -> POST recall returned the stored fact
|
||||
* verbatim, no LLM call in the response.) The separate POST .../reflect
|
||||
* endpoint is the LLM-synthesized path (used only by the optional
|
||||
* hindsight_reflect tool below, never by the forced hooks).
|
||||
*
|
||||
* Key simplification vs. the Cognee plugin: no cognify-sweep machinery.
|
||||
* Cognee needed an explicit, throttled background "cognify" step (dirty-set
|
||||
* tracker + persisted state + per-dataset throttle) to turn raw added text
|
||||
* into graph facts. Hindsight's retain endpoint does extraction, embedding,
|
||||
* dedup, and entity/temporal linking server-side as part of the retain call
|
||||
* itself (async:true just makes that happen off the request path) — so the
|
||||
* whole class of "sweep never got re-armed after a hot-reload" bugs the
|
||||
* Cognee plugin had to work around does not exist here. There is nothing to
|
||||
* port.
|
||||
*
|
||||
* Bank scoping: a single shared bank ("adolf" by default), NOT per-chat
|
||||
* datasets like the Cognee plugin used. Two reasons this diverges from the
|
||||
* Cognee reference:
|
||||
* 1. H2 (kb #74) already pointed the MCP tool surface at a single bank
|
||||
* (mcp.servers.hindsight -> http://hindsight:8888/mcp/adolf/). If this
|
||||
* plugin's hooks wrote to per-chat banks instead, a fact the model
|
||||
* stores/recalls via the MCP tools would live in a different bank than
|
||||
* the one the forced hooks read/write, silently fragmenting memory.
|
||||
* 2. Cognee's per-chat "datasets" were explicitly a best-effort mitigation
|
||||
* for a backend that leaks across datasets when
|
||||
* ENABLE_BACKEND_ACCESS_CONTROL=False (see the old plugin's
|
||||
* `datasetFor` comment) — i.e. Cognee could not do real isolation, so
|
||||
* splitting by chat was the closest available approximation. Hindsight
|
||||
* banks are hard, real isolation; Adolf has exactly one owner/DM
|
||||
* allowlist (see channels.matrix.dm.allowFrom in openclaw.json), so
|
||||
* there is no isolation need that per-chat banks would actually solve
|
||||
* here — they would only fragment recall across a single user's own
|
||||
* conversations. The chat/session id is still attached to each stored
|
||||
* turn as free-text `context` for provenance/debugging, without
|
||||
* affecting bank-level isolation or recall filtering.
|
||||
*
|
||||
* Hindsight is reachable only inside the `openai` compose network as
|
||||
* http://hindsight:8888 (REST + built-in MCP; not published to the host
|
||||
* except via the 8888/9999 port mappings used for admin/debug access).
