Changelog.

💭 Watch your model think

• See the reasoning unfold — models that "think" before they answer now stream that step-by-step reasoning into Canto as it happens.
• Cleanly separated — the thinking is tucked into its own collapsible block, so your final answer stays clean and easy to read.

📏 Context sizes you can trust

• Real numbers, not a placeholder — local connections no longer show a misleading "256K". Canto discovers a model's actual limit where it can, and falls back to a sensible value otherwise.
• Set it exactly — a handy preset picker lets you tell Canto a model's true window in a couple of clicks, and the context meter updates instantly.
• The meter finally agrees — the "how full is the model" bar now reflects your real limit, so warnings and auto-compaction kick in at the right time.
• Your settings stick — a context size you set by hand is remembered and survives refreshing your list of models.

🛠️ Smarter tool detection

• A fair test — Canto now gently warms a model up before checking whether it can use tools (reading notes, searching the web, editing documents), so big models aren't penalized for being slow to load.
• More patience for heavy models — the check waits longer for large local models, so a capable 9B model is recognized just like a quick 4B one.
• Have the final say — if the automatic check ever gets it wrong, you can switch tool support on or off for any model yourself.

🎯 Friendlier limits & refinements

• Plain-language memory warnings — if a local model runs short on memory mid-request, Canto explains what happened and suggests how to fix it, instead of showing a cryptic error.
• Cleaner structured replies — oMLX models now return tidy, well-formed results when Canto asks for structured output.

♻️ Long chats that never hit a wall

• Auto-compaction. When a chat starts to fill up, Canto quietly summarizes the older turns into a short recap and keeps the recent ones word-for-word — so you can keep going without losing the thread.
• Recent turns stay exact. Your latest messages are always kept verbatim, never summarized.
• "Compact now" button. Reclaim space yourself anytime, right from the context meter.
• Tune it your way. New Agent settings let you choose how soon it kicks in, how many recent turns to always keep, who writes the recap, and whether to get a gentle heads-up when it happens.
• Works everywhere. Applies to Canto Chat, the Document Agent, and Vault Chat.

📊 Diagrams you can actually explore

• Pan, zoom, and go fullscreen. Get in close on a complex diagram or open it full-screen to study the whole thing.
• Captions. Diagrams can carry a short title so you know what you're looking at.
• One-click repair. If a diagram comes out broken, a "fix" action asks Canto to mend it — and you can watch it work.
• Edit it yourself. A split-view editor lets you tweak a diagram by hand.
• Smoother while streaming. Diagrams now settle into place cleanly as a reply comes in, instead of flickering or grabbing your scroll.

🛤️ Vault Manager shows its work

• Live timeline. Vault Manager now reports what it's doing step by step — matching the look of Canto Chat and the Agent Panel — instead of a single vague status line.
• Grouped results. Drafted changes are tallied together, and anything skipped (duplicates, limits, or errors) is shown plainly.
• Peek at its thinking. Expandable thought traces let you follow its reasoning when you want to.
• Nothing hidden. If a run stops early for any reason, it tells you why.

🎯 Calmer, steadier research notes

• One health indicator. Ledger problems, uncitable claims, and weakly-supported claims now live in a single tidy popover next to the note title, instead of scattered banners.
• Citations that survive follow-ups. Ask a research note a follow-up question and its citation numbers keep resolving correctly across turns.
• Honest saves. Saving a research note always keeps the full draft and clearly flags anything that got trimmed or dropped, rather than quietly swapping in a shorter answer.
• Sturdier evidence ledger. The claims-and-sources table is more reliable to build, and claims trace back to the sources you actually see cited.

🛠️ Smaller fixes & refinements

• Roomier chat layout. The Canto Chat split and editor minimum width were retuned so narrow side-by-side layouts stay comfortable to work in.
• Clearer embedding status. The background indexing indicator now names the note or link it's currently working on.
• Protected note metadata. Research notes are better guarded against accidentally losing their title or misplacing the tag row while you edit.
• Tidier numbers and tables. Context-window sizes display as clean round values, and currency symbols in tables are no longer mistaken for math.

🔗 Citations that belong to the note

• References are now owned by the note itself, so numbering is always correct.
• Reorder your sources and the whole note renumbers itself to match.
• Citations stay linked to the right source even as you edit.
• The References section is protected so the AI can't accidentally scramble it.

📚 A reference registry you can manage

• A dedicated panel lists every source a note cites, with how often each one is actually used.
• Reorder, edit, and add sources — the note updates to match.
• "Remove all uncited" clears out sources that were gathered but never used.
• See when a reference is also used in other notes, so you don't lose useful ones.
• "Rebuild from body" reconstructs the registry from the note's content if things ever drift.

🔎 Citation hover cards

• Hover any citation to see the source, domain, and a quick reliability read — without leaving your place.
• See how often the source is cited here and whether it appears in other notes.
• Jump to the source or work with the reference right from the hover card.

⚠️ Citation health check

• When Canto writes a research note, it tells you upfront how many claims it could and couldn't back with a source.
• Citation markers that don't point to a real source are cleaned up instead of left dangling.
• Dismiss the banner anytime, or tell it not to show again for that note.

🧾 Evidence Ledger

• A structured table of a note's key claims, the sources supporting (or contradicting) each, and a confidence rating.
• Color-coded high / medium / low confidence at a glance.
• Thinly-supported or contradicted claims get a subtle underline in the note body.
• "Insert as section" makes the ledger a permanent part of the document when you want it.

🔄 Living research notes

• Come back to a Canto-authored research note later and choose "Update this research" to re-run it.
• A merge view summarizes new sources, new or revised claims, confidence shifts, and new contradictions before anything changes.
• Review the diff and choose to merge or discard — a refresh never silently rewrites your work.

🎯 A calmer, faster vault

• Related Notes suggestions are sharper and arrive with less churn.
• The Knowledge Graph stays responsive on very large vaults and tells you when it's trimmed for speed.
• An open Knowledge Graph tab now restores after you restart Canto.
• The local AI's indexing engine no longer gets unloaded mid-job, so background work finishes cleanly.

🛠️ Smaller fixes & refinements

• Stray internal scaffolding (like "next steps") no longer leaks into notes Canto writes for you.
• Saving a research note never drops a citation it had just shown you.
• A labeled spinner shows when Canto is building citations, the ledger, and references.
• Research notes get tidy role labels in the margin (Summary, Methodology, References) to make long documents easier to scan.

👀 Know the Impact Before You Confirm

• Before deleting, Canto shows you how many notes will be affected and which ones.
• You can see how much indexed content will be removed, with a clear warning that the action can't be undone.

📎 Note Attachments Join the Library

• Files attached directly inside notes now appear in the Library, marked as Indexed.
• These attachments are included in vault-wide search when Canto Chat is set to use all your notes.
• Whether a file came from chat or from a note, it now lives in the same Library view.

🪄 Smarter Drag-and-Drop

• Dragging a file from the sidebar into the editor now drops a real attachment you can open — not just plain text.
• Dragging a note in creates a working link instead of the note's title as text.
• The Library refreshes quietly in the background and attachment indicators update on their own.

🧰 A Better Vault Manager

• The Vault Manager chat now uses the same polished composer as Canto Chat, with quick-action presets built in.
• You can choose your model directly from the Vault Manager.
• A context meter shows how much room the vault scan, note reads, and the drafted plan are using as the agent works.
• Smarter handling avoids repeating the same folder actions on smaller models.

📊 Live Context Usage

• The context meter now updates while Canto is working, not just when it finishes — so you can see context fill up in real time.

🧠 Memory, One Click Away

• Open the adaptive Memory dashboard right from Settings → AI Models.
• High-memory Macs now get higher recommended context limits, so guidance matches what your machine can handle.

🧺 Inbox Mode Polish

• Related-note suggestions are now drawn from real source content, not just titles and metadata.
• A compact run strip stays pinned near the composer, so you can apply, retry, or jump to a run without scrolling.
• A new Start Over option discards a suggested plan and returns you to the composer — without touching your vault.
• Citations stay cleaner: existing labels are preserved and reference lists stay tidy.

🛠️ Smaller Fixes & Refinements

• Attachment indicators update right after a file is recognized — no manual reload needed.
