Extractor Kind

Extractor Kind

Definition

Planned closed enumeration on q_a_extractions.extractor_kind capturing which extractor produced a Q&A extraction event: a mempalace mining pass, one of the cocoindex pattern adapters (A/B), a generic LLM extraction call, or a derivation from a prior bid response. Pipeline-side, platform-internal vocabulary. CORE per §6.2.

Synonyms / Acronyms

• “Pattern A/B” refers to the legacy Phew migration parsers — fate per Finding 04 §3.5 (likely retired in favour of cocoindex Pattern A/B adapters per Prereq 2a top recommendation #1).

Baseline values

key	label	provenance
mempalace_miner	Mempalace Miner	core
cocoindex_pattern_a	Cocoindex Pattern A	core
cocoindex_pattern_b	Cocoindex Pattern B	core
llm_extraction	LLM Extraction	core
prior_bid_response	Prior Bid Response	core

Relationships

• q_a_extractions.extractor_kind — planned column (table not yet in production schema).
• Bound to the cocoindex flow per Prereq 2a recommendation #1 (ExtractByLlm-based typed flows).
• Adjacent to CV 22 origin_kind — extractor_kind says “which tool extracted”, origin_kind says “what kind of source it came from”.
• Layer 2: extractor kind is administrative metadata recording the extraction provenance.

Consumers

• Q&A extraction pipeline (planned; will live in scripts/kb_pipeline/ or lib/extraction/).
• Quality / audit trails (which extractor produced which pair).
• Cocoindex monitoring (CocoInsight per source §3.7).
• lib/mcp/tools/search.ts — future MCP filter when column lands.

Notes

• Status: planned — column not yet in production schema.
• Closed CV; schema migration adds new values.
• Pattern A/B parser fate (B1 in 00-synthesis) deferred to cocoindex prereq sessions per source §7.
• Source §2.1 lists the initial 5 values; expansion likely as the cocoindex flow library grows.
