Graft keeps a derived, disposable code graph in sync with a content hash rather than a calendar, and keeps a protected block on every regenerated node. This KB is the opposite kind of store — durable, curated, built from material that cannot be regenerated — but several of Graft's mechanisms port cleanly, and two of them close real gaps here. Schema 1.5 is additive: every 1.4 page remains valid. 1. `## Crux` — verbatim source excerpts alongside the synthesis. A summary can drift silently; a quote either still matches its source or it does not. Lets `ckb-retrieve` ground an answer without a round-trip to the archive, and makes drift mechanically detectable. 2. `## Notes` — human-authored and protected everywhere. Closes a real gap: `ckb-index-external` regenerates connector pages wholesale, so an annotation written there was previously destroyed on the next refresh. 3. `source_fingerprint`/`source_checked` — a digest of the material a page was built from. Freshness by date says a page has aged; a fingerprint says whether its evidence moved. Most valuable for connector-backed libs, where documents change with no notice. 4. `lint_report.py --quick` — a deterministic one-line session-start signal, wired into Rule E next to the existing `git status` check. 5. In-degree as a rank-fusion signal in `ckb-retrieve`, weighted below 1.0: centrality is a prior, not evidence. 6. Blast radius — a new `ckb-ingest` step walking the graph backwards from touched entities to find what the incoming material contradicts, before writing anything. Ingest was additive-first, which is how a wiki accumulates two pages that quietly disagree. 7. Edge vocabulary in `wiki/graph/index.md` rewritten as a question per verb, and completed: `part_of` was written by `ckb-code-map` but never declared. Added `produces`, `configures`, `validates`, `implements`. Lint gains checks 12 (fingerprint drift), 13 (crux verbatimness) and 14 (the protected-Notes rule), verified against a synthetic fixture covering stale digests, missing sources, fabricated quotes and paraphrased evidence. Not adopted: the gitignored regenerable store, the MCP server and CLI daemon, tree-sitter parsing, statusline hooks, telemetry. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Knowledge Base Index
Routing table: read the Use when column to decide if a page is relevant.
| Page | Description | Use when |
|---|---|---|
| Overview | High-level map of the knowledge base | Getting started, understanding the structure |
| Log | Chronological record of root-level changes | Reviewing recent modifications |
| Error Book | Known compilation errors and fixes | Debugging a bad ingest or lint issue |
| Projects | Optional local query scopes grouping related wiki pages, sources, libs, and graph areas | Narrowing search to a team, topic, client, system, or initiative |
| Query Gaps | Questions the wiki could not answer yet, used to drive demand-driven ingest | Tracking failed searches, missing knowledge, future ingest targets |
| Decisions | Numbered decision records — what was decided, by whom, when, why, and what it superseded | Asking why something is the way it is, who decided it, when, what changed it, or what is still open |
| Entities | Typed entity pages (people, projects, libraries, concepts) | Looking up a specific person, project, library, or concept |
| Graph | Edge lists and relationship data between entities | Finding what depends on / relates to a given entity |
Entity Pages
Pages in entities/ describe typed entities (people, projects, libraries, concepts)
extracted during ingest. See Entities index /
entities/index for the full list. Each links to related entities via the
graph index.
(Agent populates this as entities are extracted.)
Decision Records
Pages in decisions/ are numbered decision records (NNNN-slug.md). Unlike
entity pages, they are append-only: a decision is never rewritten to match a
later change of mind — a new decision supersedes it and both stay on the
record. See Decisions index /
decisions/index. Say "record a decision" to add one.
