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.

Decision log (VERSION 1.6.0, kb_schema_version 1.4):
- wiki/decisions/ scaffold — numbered NNNN-slug.md records, own index
(with status vocabulary) and log
- type: decision adds status/decided_on/decided_by/affects/review_on;
supersedes/superseded_by carry history and must be set on both sides
- New ckb-decide skill: records decisions and answers what/why/who/when,
what superseded what, and what is still open. Decision pages are
append-only — a changed mind is a new superseding decision
- Graph gains decided_by and affects edge types
- ckb-ingest routes decisions found in raw material to this format;
ckb-retrieve gains the decisions index as a cascade step
Scriptified the mechanical skills:
- ckb-export-okf/scripts/export_okf.py does the whole OKF transform
(frontmatter remap, link rewriting, index/log regeneration, conformance
validation); --check validates without writing
- ckb-lint/scripts/lint_report.py does the read-only detection half
(conformance, freshness, confidence, retention, decisions, orphans,
graph, index/log, source.yaml); judgment calls stay with the model
Also: removed the duplicate personal quiz skill, fixed stale cbk-quiz
doc paths, gitignored __pycache__.

ckb-index-external now goes beyond one page per document: it also
extracts people, organizations, projects, decisions, systems, and
processes each document discusses into thin, pointer-style entity
pages within the connector's own index (evidence back to source
documents, deferring to a full wiki/entities/ page where one already
exists), so the index supports "what do we know about X" lookups, not
just "what documents exist here".
New ckb-retrieve skill formalizes the retrieval half of the query
workflow: before grounding an answer in a page's tldr, follow it back
to its underlying source (a wiki page's Sources citations, or a
connector page's resource: pointer) rather than trusting the
compressed index entry as settled.
