+Issue: #189
+
+Command:
+
+```powershell
+cargo audit --no-fetch --stale
+```
+
+Result summary:
+
+- Vulnerabilities: 0
+- Informational warnings: 13
+- Advisory DB: local stale/offline mode, 900 advisories loaded
+- Cargo.lock dependencies scanned: 758
+
+`cargo audit` reports these as allowed informational warnings because the
+current audit settings include `unmaintained`, `unsound`, and `notice`.
+
+## Active warnings
+
+| Advisory | Crate | Path | Reachability | Action |
+| --- | --- | --- | --- | --- |
+| RUSTSEC-2024-0413 | `atk 0.18.2` | `tray-icon -> libappindicator/gtk -> atk` | Linux desktop tray only, via optional `gui` feature. | No patch release exists in GTK3 bindings. Requires tray backend replacement or Linux tray feature split. |
+| RUSTSEC-2024-0416 | `atk-sys 0.18.2` | `tray-icon -> libappindicator/gtk-sys -> atk-sys` | Linux desktop tray only, via optional `gui` feature. | Same as GTK3 tray migration. |
+| RUSTSEC-2024-0412 | `gdk 0.18.2` | `tray-icon -> libappindicator/gtk -> gdk` | Linux desktop tray only, via optional `gui` feature. | Same as GTK3 tray migration. |
+| RUSTSEC-2024-0418 | `gdk-sys 0.18.2` | `tray-icon -> libappindicator/gtk-sys -> gdk-sys` | Linux desktop tray only, via optional `gui` feature. | Same as GTK3 tray migration. |
+| RUSTSEC-2024-0415 | `gtk 0.18.2` | `tray-icon -> libappindicator/gtk` | Linux desktop tray only, via optional `gui` feature. | Same as GTK3 tray migration. |
+| RUSTSEC-2024-0420 | `gtk-sys 0.18.2` | `tray-icon -> libappindicator/gtk-sys` | Linux desktop tray only, via optional `gui` feature. | Same as GTK3 tray migration. |
+| RUSTSEC-2024-0419 | `gtk3-macros 0.18.2` | `tray-icon -> gtk -> gtk3-macros` | Linux desktop tray only, via optional `gui` feature. | Same as GTK3 tray migration. |
+| RUSTSEC-2024-0429 | `glib 0.18.5` | `tray-icon -> gtk/libappindicator -> glib` | Linux desktop tray only, via optional `gui` feature. The project does not call `glib::VariantStrIter` directly. | Patched in `glib >=0.20`, but current `tray-icon 0.24.1` still resolves GTK3/glib 0.18. Requires upstream tray dependency migration. |
+| RUSTSEC-2026-0002 | `lru 0.12.5` | `ratatui 0.28.1 -> lru` | TUI dependency. Project does not call `lru::IterMut` directly; exposure is through ratatui internals. | Patched in `lru >=0.16.3`. Requires `ratatui` upgrade beyond current `0.28` line and TUI compatibility verification. |
+| RUSTSEC-2024-0436 | `paste 1.0.15` | `ratatui 0.28.1 -> paste`; also `slint-build/slint -> image -> ravif -> rav1e -> paste` | Build/runtime transitive dependency. Project does not use `paste` directly. | Requires upstream dependency updates: ratatui upgrade for TUI path and Slint/image/ravif updates for Slint path. |
+| RUSTSEC-2025-0141 | `bincode 2.0.1` | `slint-build/slint -> i-slint-compiler -> typed-index-collections -> bincode` | Build-time Slint compiler path. Not used by vimit runtime code directly. | Requires Slint compiler dependency change upstream or a Slint upgrade that removes it. |
+| RUSTSEC-2025-0119 | `number_prefix 0.4.0` | `self_update 0.41.0 -> indicatif 0.17.11 -> number_prefix` | CLI/GUI self-update progress dependency. Project does not use `number_prefix` directly. | `self_update 1.0.0-rc.2` exists but is pre-release and likely API-impacting; defer to dedicated migration. |
+| RUSTSEC-2024-0370 | `proc-macro-error 1.0.4` | `tray-icon -> gtk3-macros/glib-macros -> proc-macro-error` | Linux desktop tray compile-time macro path. | Same as GTK3 tray migration. |
+
+## Dependency posture
+
+- `tray-icon 0.24.1` is the latest published `tray-icon` release, but its
+  default Linux backend still pulls GTK3/libappindicator crates with RustSec
+  unmaintained warnings.
+- `ratatui 0.28.1` is behind latest `0.30.2`; moving to `0.30.x` is a TUI
+  migration rather than a lockfile-only update.
+- `slint 1.16.1` is behind latest `1.17.0`; the project has active Android
+  Slint risk tracking, so this should be handled as a GUI/Android migration
+  with APK validation rather than folded into this audit-only issue.
+- `self_update 0.41.0` latest is `1.0.0-rc.2`; this is not a low-risk stable
+  patch update.
+
+## Low-risk updates
+
+No low-risk patch updates were available inside the current version
+constraints:
+
+```powershell
+cargo update -p ratatui --dry-run
+cargo update -p self_update --dry-run
+cargo update -p tray-icon --dry-run
+cargo update -p slint --dry-run
+cargo update -p slint-build --dry-run
+```
+
+Each dry run locked 0 packages. The remaining fixes require explicit
+migration work, not opportunistic lockfile churn.
+
+## Follow-up work
+
+- #200: Migrate TUI from `ratatui 0.28` to `0.30.x` and verify snapshots/rendering.
+  This is the path to remove `lru 0.12.5` and the ratatui-side `paste`.
+- #201: Evaluate the desktop tray backend: either replace `tray-icon` on Linux,
+  split tray support behind a narrower feature, or accept/document GTK3
+  warnings until `tray-icon` moves off GTK3.
+- #202: Evaluate `slint 1.17.x` after Android smoke checks stabilize, because the
+  Slint compiler/build graph is responsible for `bincode` and one `paste`
+  path.
+- #203: Evaluate `self_update 1.0.0-rc` only after release/update behavior is covered,
+  because it is a pre-release major API change.
