Port of KOS v1 knowledge/meta/evidence-levels.md.
| Level | Name | What qualifies |
|---|---|---|
| E0 | Unverified observation | Intuition, single chat mention, provisional note |
| E1 | Single source | One document, one message thread, one meeting |
| E2 | Multi-source consistent | ≥2 independent sources align |
| E3 | High-confidence factual record | Official docs, system config, verified repeatable state |
| E4 | Decision-grade conclusion | Adopted in real operations, behavior-shaping, durable |
kind | Min evidence for durable claim |
|---|---|
source | E1 (by definition — captures one source) |
concept | E2 — concepts must be multi-sourced |
synthesis | E2 — synthesis bridges multiple sources |
comparison | E2 per compared item |
decision | E3+ — decisions change real behavior |
protocol | E3+ — protocols are executed by the system |
project | E1 for description, E2 for "current state" claims |
entity (person) | E1 for existence, E2+ for beliefs/motivations |
Every durable judgment on a page must carry an explicit evidence level. Frontmatter format:
evidence_summary:
primary: E3
claims:
- claim: "Omada software org reports to Lucien"
level: E3
source: "~/.openclaw/workspace/USER.md"
- claim: "User prefers Chinese-first responses"
level: E4
source: "operational observation since 2025-10"
For unstructured pages, inline tag [E2] or [E3] after claims in prose.
Before accepting a put_page call with kind in {decision, protocol, concept, synthesis, comparison}:
evidence_summary OR scan body for [E\d] inline tagskind: synthesis if E2 is sufficient,

Classify vector-similar pages against each orphan page via Haiku 4.5 and add typed inbound references (link_type="related", relation encoded in context). Goal: chip away at the 1803/1952 orphan pile (v1 wiki flat import) across multiple sweep runs. Default is --dry-run; --apply does DB link inserts + markdown sentinel upsert on candidate pages that exist on disk, then commits ~/brain changes.
Merge WITHIN-SOURCE duplicate entity-variant pages (e.g. people/lucien + people/lucien-chen, companies/tp-link-system-inc + tp-link-systems-inc) into one canonical node: repoint links + facts + display-name aliases, register a slug redirect, soft-delete the alias pages. An LLM disambiguates each cluster (merge / ambiguous / distinct); ambiguous first-name-vs-multiple-full-names cases are quarantined, never merged. Default --dry (simulate + report, zero writes). Cross-source pages are NEVER touched — the two-axis design keeps them legitimately separate.
One-shot sweep that reads every page in the brain, extracts every person/company/concept/project mentioned via Haiku NER, dedupes, tiers by mention count + context, and creates stub pages for entities that lack one. Tier 2 candidates get Tavily web-search augmentation; Tier 3 stays brain-only (confidence: low). This is the primary G1 payoff skill from JARVIS-NEXT-STEPS.md §5.
Daily sweep: runs kos-lint + staleness detection + knowledge-gap analysis, then produces a MEMORY-format digest ready to be appended to OpenClaw's MEMORY.md by the digest-to-memory skill (Sun 22:00 weekly). Also writes a dashboard to ~/brain/agent/dashboards/knowledge-health-<date>.md.
Bridge an upstream gap: extract_atoms never stamps `frontmatter.concepts` on page-derived atoms, but synthesize_concepts consumes ONLY that field — so concept synthesis is permanently skipped ("no atoms with concept refs"). This script batch-labels atoms lacking the field with 1-3 kebab-case shared-vocabulary topic labels (sonnet) and stamps them, so upstream synthesize_concepts can tier + materialize concepts/<label> pages. Idempotent: only touches atoms WITHOUT `concepts`; safe to rerun after each extract_atoms drain. Retires when the upstream fix lands.
One-command bulk-ingest pipeline (D→I→K→W) for a single isolated source. Sequences the 7 fork stages — register → ingest → embed → enrich → graph → (per-entity synth, opt-in) → corpus-synth — over a folder of frontmatter'd .md files, each idempotent/incremental so re-runs only do new work. Turns a systematic corpus (product docs, FAQ, a research library) into a queryable knowledge asset: facts (RAG) + entities + graph + corpus-level viewpoints.
