Document top-down and bottom-up writing, lazy title/abstractor/visual that
persist after generation, and per-field regenerate plus lock. Wire into
capability model and stage-1 notes.
Document coulomb layering (NetKingdom, Railiance, PageOps, markitect-tool),
compare thin store vs shard-wiki vs kontextual-engine, and outline asset-store
extraction from kontextual BlobStorage. Include executable spike checklist.
Capture preferred layering (NetKingdom, Railiance, coulomb UI, markitect-tool
as markdown lib, DB as cache). Treat markitect-main as legacy; evaluate
shard-wiki as thin-slice content plane candidate.
