Index: .notescraft/cache/index-v1.bin keeps per-note link info, search doc, knowledge passages and lint votes keyed by (mtime, length), re-checked by stat at import; changed notes re-read; corrupt, truncated, oversized or old caches ignored and replaced. The knowledge vocabulary is trusted only by file hash (the old note-count check made a second open slower than a cold one). mdn-docs (14.7k notes, release): second open 1.4 s instead of 15.7-21 s cold.
Calendar: a per-session cache of what each note's scan gave the agenda (parsed events, all dated tasks) validated by length and mtime; window switches only filter in memory (mdn-docs 695 ms -> 2.7 ms), the cold pass runs in 8 ms slices across frames while the old grid stays visible, the week review reuses loaded items.
Built by Claude Sonnet; verified from a clean checkout of the staged files: 1901 tests in engine, index, knowledge and ui-egui lib plus calendar_view pass, clippy -D warnings on the four crates, xtask layers, tree and i18n clean.
