 ## [Unreleased]
 
+### Added
+
+- **Suppression Code Actions (`LSP-FEAT-003`)**: The LSP server now dynamically generates "Suppress this finding" Code Actions for all suppressible diagnostics. Clicking the action automatically injects the correct `<!-- zenzic:ignore:ZXXX -->` comment above the offending line. This feature is strictly disabled for `NON_SUPPRESSIBLE_CODES` (Z2xx Security findings) to enforce the security gate.
+
+### Fixed
+
+- **LSP State Hygiene (`LSP-FIX-015`)**: Eradicated "ghost diagnostics" by ensuring the LSP server explicitly sends an empty diagnostics array (`[]`) to VS Code when a file is deleted, clearing the PROBLEMS panel.
+- **Code Action Routing (`LSP-FIX-016`)**: Fixed a routing bug in the LSP server that prevented Quick Fixes for `Z108` (Empty Link Text) and `Z505` (Untagged Code Block) from appearing in the editor.
+- **Z603 Parity (`LSP-FIX-015`)**: Ensured HTML comment suppressions (`<!-- zenzic:ignore -->`) are correctly evaluated for "dead" status in the LSP engine.

+## Inline Diagnostics & Code Actions

+The extension exposes real-time LSP diagnostics directly in the PROBLEMS panel and editor margin.
+
+Zenzic provides automated Quick Fixes for specific structural and content findings (e.g., injecting placeholder text for empty links `Z108`, adding language tags to code blocks `Z505`, and removing dead suppressions `Z603`).
+
+In addition, Zenzic offers automated "Suppress this finding" Code Actions (`<!-- zenzic:ignore:ZXXX -->`) for all suppressible diagnostics. Hovering over a finding allows you to insert an inline suppression directive on the line above with a single click. To enforce security governance, suppression Code Actions are intentionally disabled for Security findings (`Z2xx`), which must be remediated at the source.
