Implements the HF side of Plexum DESIGN-DYNAMIC-BLOCK.md Phase 2 — the
HarborForge knowledge-base block agents cache facts into per session.
Cross-runtime aligned with the ClawSkills workflow text (same tool
names + input schemas + return shapes will land on openclaw side later).
manifest.json:
- 5 new dynamic-kb-* tool contracts (list-kbs / list-topics /
list-facts / cache / evict)
- dynamicSubblocks contract entry declaring this plugin owns
the "kb-block" <dynamic-block> subblock
internal/kbblock/ (new):
- Per-session storage at <PLEXUM_PROFILE_ROOT>/agents/<id>/sessions/
<sid>/plugins/harbor-forge/kb-block.json
- Entry carries ID (HF backend DB primary key) + KBCode + SourceTopic
+ Content + InsertSeq for §9 #4 cache-insertion-order rendering
- Render emits <kb-fact id=N kb=<code> source=topic:<slug>>...
</kb-fact> (no title/description per §9 #8; source attr omitted
when empty)
- Fade NOT applied in v1 — §9 #3 lock has fade params shared with
memory but implementation deferred until prod data informs whether
KB needs it; agent dynamic-kb-evict is the only eviction path
- 11 unit tests
internal/kbclient/ (new):
- Typed HTTP client for HarborForge.Backend KB routes verified
against app/api/routers/knowledge.py
- GET /knowledge-bases[?project=<code>] (list KBs)
- GET /knowledge-bases/{kb_code}/topics (list topics)
- GET /knowledge-bases/{kb_code}/tree (full hierarchy — ListFacts
flattens this client-side filtered by topic ids; backend has no
flat list-facts-in-topic route)
- GET /knowledge-facts/{id} per fact (GetFacts batch loop)
- Auth: plugin-level Bearer APIKey. Per-agent hf-token resolution
is a TODO when SDK exposes secret-mgr access.
internal/tools/kb.go (new) + tools.go:
- 5 tool functions hooked into Dispatch
- KBDeps struct bundles Client + ProfileRoot + SessionFor + Turn
- Cache/evict use SessionFor lookup populated by main.go's
RenderDynamicSubblock (called per turn by host; carries sessionID)
cmd/plexum-harborforge-plugin/main.go:
- kbClient field initialized when BackendURL + APIKey present
- profileRoot cached for kbblock path resolution
- agentSession sync.Map tracks agentID → sessionID; populated by
RenderDynamicSubblock so subsequent tool calls in the same turn
can resolve the per-session kb-block.json path
- Implements sdkplugin.DynamicBlockProvider.RenderDynamicSubblock:
opens kbblock for (agentID, sessionID) and returns its Render()
body; host wraps in <kb-block>...</kb-block>

Plugin id `harbor-forge` mirrors the OpenClaw counterpart's runtime
surface on top of the Plexum SDK:
* eager activation — Monitor bridge + Calendar scheduler boot at
host start, before any agent turn fires
* monitor bridge: HTTP 127.0.0.1:<monitor_port> serving /telemetry
+ /health for HarborForge.Monitor
* calendar scheduler: heartbeats <backendUrl>/calendar/agent/
heartbeat, dispatches returned slots via HostAPI.WakeAgent
(state-aware queue, depth-1 replace-newest), tracks active slot
state in-memory, terminal status pushed back to backend
* 9 harborforge_* tools (status / telemetry / monitor_telemetry /
calendar_{status,complete,abort,pause,resume} / restart_status)
Key differences from OpenClaw equivalent:
* api.spawn → HostAPI.WakeAgent (new SDK primitive)
* api.getAgentStatus → HostAPI.ReadAgentState (existing)
* --install-monitor / --install-cli not included; Monitor + hf CLI
deploy via the HangmanLab.Server.T3 docker compose layer
Initial drop. TODO before v1 ship:
* tool ctx → calling-agent-id: SDK doesn't currently expose; v1
falls back to a single-active-slot heuristic in
main.bestEffortAgentID
* tests for the bridge + scheduler
