v0.24.0 — corpus-scale retrieval, source gists, global answers

Highlights

• Retrieval that holds up at scale. Notebooks now stay fast and accurate well past a few million characters — the search quality fence is verified flat from 1M to 10M chars. The sources gauge reflects this: it measures where you are against a 10M scale target instead of warning about a capacity wall that no longer exists.
• Source gists. Every source gets a short distilled overview in the background, so corpus-wide questions ("what's in here?", "which source covers X?") find the right document even when no single passage is an obvious match. Folders show their own contribution to the total at a glance.
• Global answers over your whole library. Ask something broad — "summarize the themes across my sources," "what do these disagree on?" — and the answer is assembled from every relevant source, not just the closest few passages.
• Sharper page-capture retrieval. Captured web pages get a per-chunk context pass and shed navigation cruft, so search over clipped articles reads much closer to search over clean documents.
• Code files render with syntax highlighting in the reader, with find-in-source over the colored view.
• Color is back on the studio generator types — a quiet per-family accent on the generator buttons and note icons, for at-a-glance wayfinding.
• A calmer sources list. Rows carry only what's actionable (NotebookLM-style), folders remember open/closed across restarts and appear instantly with an embedding-progress indicator.

Fixes

• Importing a folder containing a malformed or encrypted PDF no longer panics or hangs the import — the bad file is flagged and the rest imports normally.
• Deleting a large folder no longer times out; the whole tree is removed in one pass.
• Generating a summary no longer produces a duplicate note card.
• The select-all control at the top of the sources list no longer reads as a blank, menu-less source.
• Long Settings tabs scroll again; the Settings header is now part of the nav.
• The vision-OCR gateway model is a dropdown of your gateway's models instead of a free-text field.
• Numerous background-distillation quality and stability fixes (index-rebuild races, gate tuning so accurate summaries aren't rejected, faster bulk ingest).

Notes

Background distillation (source gists and page-capture enrichment) runs after import, is gated for quality, and degrades to prior behavior on any failure. It's on by default and can be turned off in Settings → Models if you'd rather not spend the local model time.
