The session store rebuilt the rag namespace from four known keys, so the
evidence record never survived a turn, let alone a reload from localStorage.
Compaction then ran with an empty ledger: earlier evidence was replaced by
receipts retaining nothing, while the citations already in citation_index kept
the UI looking correct.
The UI still names the fields it reads, but everything else in the namespace
passes through untouched, and seeding the namespace no longer replaces sibling
namespaces.
visualize_chunk re-expanded chunks from scratch to recover their refs,
which could not faithfully reproduce the original merge, scores, and
clip — so a visualization could highlight different pages than the
citation covered. Carry the cited items on Citation.doc_item_refs and
resolve bounding boxes from them directly; re-expansion remains only as
the fallback for callers with no stored context (CLI, inspector). Chat,
inspector, the app endpoint, and the frontend pass the refs through.
