 Each note owns its outbound typed relationships in frontmatter. KB derives backlinks, inverse edges, and bounded traversal at read time, so parallel agents do not contend on one generated fact file. `kb percolate <note>` reports recurring concepts and missing-link candidates with inspectable support but writes nothing. An agent reads the cited notes before creating a reusable concept or relationship. Semantic similarity never creates an edge automatically.
 
+Percolation Result V2 presents a missing relationship as an unordered pair of
+notes with a required predicate. It does not choose the source, direction, or a
+`related-to` fallback. Recommended authored predicates include `synthesizes`,
+`evidenced-by`, `informed-by`, `supersedes`, and `contradicts`; they are an
+advisory vocabulary, so a vault can use another canonical predicate when its
+prose and evidence define the claim. KB never infers reciprocal, inverse,
+transitive, or similarity-derived relationships.
+
 Git provenance is opt-in. A search without `--history` performs no Git indexing. `--history` requests best-effort provenance, while `--require-history` rejects unavailable history or incomplete provenance for the selected notes. If one commit exceeds the 2,000-path detail limit, KB retains its identity and vault-local note associations, marks its co-change detail incomplete, and continues through later commits. Best-effort search reports that requested lane as partial.
 
 Local attachment checks cover Markdown and Obsidian references to images, PDFs, and editable tldraw sources. They reject missing or escaping files while leaving external URLs alone. A source-inbox view separately lists recent captures that have no inbound disposition from maintained knowledge. It is an advisory, not an automatic backlink requirement: a saved source may intentionally remain a leaf.

 Search finds candidates. Similarity does not establish that a passage is current, correct, or supported by its sources. The Markdown, cited captures, explicit relationships, and requested Git history supply the material a reader must inspect.
 
+### Customize through an approved proposal
+
+The Agent Skill routes setup and evolution requests before it prepares a
+runtime. It inspects the proposed location without mutation, interviews the
+user about the memory questions the KB should answer, and presents exact read
+and write targets. Only the approved targets may be scaffolded. A changed path,
+repository, account, integration, or companion skill requires renewed
+approval.
+
+The standard router may be enough. A recurring ritual can instead receive a
+companion skill with explicit inputs, authority, durable outputs, idempotence,
+failure behavior, and verification. These skills are inert instructions. They
+do not create a plugin runtime, execute vault metadata, inherit ambient account
+access, or couple application code to the KB. An exact repeat is a no-op;
+divergence, path escape, symbolic links, partial writes, and unapproved
+external surfaces stop the workflow.
+
+The repository's fake-capability suite exercises those transitions. It is a
+tested contract example, not proof that every agent or host integration
+complies.
+
+This workflow builds on Frank Chen's public notes about [designing a personal
+knowledge base with an
+agent](https://gist.github.com/fxchen/773397095d7a6bffda621e4237da0da9)
+and [extending it with
+skills](https://gist.github.com/fxchen/09cb410b22c9c5256d80243ee925b57e).
+
+KB ships no `kb_role` metadata, lifecycle resolver or API, lifecycle CLI,
+compatibility diagnostic, or metadata migration. A frozen Phase 0 value gate
+must show that those surfaces improve deterministic agent decisions before they
+are introduced. Current and historical plan routing remains derived from
+existing type, path, and status conventions.
+
 ### Adopt the smallest useful split
 
 Start with a short inherited `AGENTS.md` path for rules whose omission would make an edit wrong. A small knowledge base may need only Markdown, Git, an index page, and ordinary file search. Add source capture when evidence keeps disappearing. Add repository scopes when agents need to recover current memory from code paths. Add metadata or hybrid search when file search stops answering the repository's questions. Add links and graph views only when the relationships themselves help people make decisions.

 ## Release notes
 
+### Upgrade to v0.19.0
+
+Version 0.19.0 adds interview-first setup and evolution guidance, a bounded
+filesystem-only companion-skill scaffold contract, and Percolation Result V2.
+V2 requires an explicit predicate and leaves relationship ownership and
+direction to review. The release does not add lifecycle metadata, a resolver,
+a lifecycle CLI, inferred edges, or automatic account and network actions.
