New placeholder that expands query keys one hop through the graph,
giving agents visibility into what's already connected to the nodes
they're working on. Excludes the query keys themselves so there's
no duplication with {{nodes}}.
Added to transfer (sees existing semantic nodes linked to episodes,
so it REFINEs instead of duplicating) and challenger (sees neighbor
context to find real evidence for/against claims).
Also removes find_existing_observations — superseded by the
per-segment dedup fix and this general-purpose placeholder.
The four knowledge agents (observation, extractor, connector,
challenger) were hardcoded in knowledge.rs with their own node
selection logic that bypassed the query pipeline and visit tracking.
Now they're .agent files like the consolidation agents:
- extractor: not-visited:extractor,7d | sort:priority | limit:20
- observation: uses new {{CONVERSATIONS}} placeholder
- connector: type:semantic | not-visited:connector,7d
- challenger: type:semantic | not-visited:challenger,14d
The knowledge loop's run_cycle dispatches through defs::run_agent
instead of calling hardcoded functions, so all agents get visit
tracking automatically. This means the extractor now sees _facts-*
and _mined-transcripts nodes that it was previously blind to.
~200 lines of dead code removed (old runner functions, spectral
clustering for node selection, per-agent LLM dispatch).
New placeholders in defs.rs:
- {{CONVERSATIONS}} — raw transcript fragments for observation agent
- {{TARGETS}} — alias for {{NODES}} (challenger compatibility)
