## New Features

- 🪟 **Separate app windows for separate vaults** — Opening a vault can now create an independent Tolaria application instance with its own runtime state, window identity, and vault lifecycle.
- 📊 **Core editor performance harness** — Added a reusable performance regression harness for large-note/editor workflows, including thresholds, statistics, traces, and CI-facing guardrails.
- 🧭 **Bottom-bar vault switching polish** — Improved the vault switcher/status-bar structure, including clearer menu behavior and reusable vault-list components.
- 🧩 **CircleCI shadow pipeline groundwork** — Added CircleCI release/CI orchestration docs and config so release gates can be observed outside the primary GitHub Actions path.

## Improvements

- ⚡ **More responsive inspector and Git history** — Moved blocking Git history work off the editor path and reduced unnecessary inspector refresh churn while preserving current-note context during refresh.
- 🎨 **Workspace color contract cleanup** — Consolidated workspace color handling and removed dynamic lookup paths that could make color behavior harder to reason about.
- 🛡️ **Fail-closed performance gates** — Tightened the performance/security gate behavior so regressions are surfaced deterministically instead of silently passing.
- 📚 **Expanded public docs and bundled agent docs** — Updated app/site documentation for rich editor, AI, media previews, Git, keyboard shortcuts, getting-started vaults, and documentation maintenance.
- 🔎 **AI agent detection improvements** — Improved local OpenCode Desktop detection and hid unsupported Windows settings probes.

## Fixes

- Fixed rich editor blank paragraph preservation across Rich ↔ Raw round trips.
- Fixed rich editor Markdown embed and portable attachment path preservation, including image/attachment serialization expectations.
- Fixed Unicode/CJK file-path copying so clipboard paths preserve non-ASCII characters.
- Fixed external links disappearing in large notes.
- Fixed display math blocks clipping vertically instead of expanding.
- Fixed saved view drag-order persistence.
- Fixed Windows note action menus auto-selecting the first item instead of staying open.
- Fixed malformed vault paths during loading and release of replaced sheet models.
- Suppressed noisy recovered-editor-depth reports while preserving real recovery behavior.

## Technical Notes

- Added ADRs for separate vault application instances, CircleCI release orchestration, and local CodeScene safeguards.
- Added local CodeScene and performance benchmark documentation plus threshold tooling.
- Refactored app icon, desktop runtime, vault instance/list, status-bar, editor serialization, markdown compaction, image, performance logging, and workspace-color internals.
- Added or expanded coverage for editor performance, rich-editor serialization, sheet replacement, saved views, startup performance, telemetry, BlockNote custom block serialization, onboarding vault persistence, and smoke coverage.
