   - Session status codes documented (D9F00: 2=Failed, 5=Completed, 8=CompletedWithErrors, etc.)
 - Updated `TODO-cove-data-protection.md` with breakthrough status and next steps
 
+### Changed
+- Cove import/link behavior and visibility refinements:
+  - Fixed Settings → Cove "Run import now" button submission issue caused by nested form markup
+  - `/cove/accounts` now shows derived fields for faster linking decisions:
+    - `backup_software` (Cove Data Protection)
+    - derived `backup_type` (Server, Workstation, Microsoft 365)
+    - derived `job_name`
+    - human-readable datasource labels
+    - `computer_name` visible in matched and unmatched sections
+  - Linking a Cove account now triggers an immediate import attempt, so latest runs can appear without waiting for interval
+  - Improved feedback after linking with per-linked-job run delta and clearer reason when no run is created
+  - Cove run enrichment:
+    - `JobRun.remark` now stores account/computer/customer/status/last-run summary
+    - per-datasource run object records now include status detail text and datasource session timestamp
+  - Cove timestamp fallback for run creation: use `D09F15`, fallback to `D09F09` when needed
+
+### Fixed
+- Cove deduplication scope:
+  - Dedup check changed from global `external_id` to per-job (`job_id + external_id`) to prevent newly linked/relinked jobs from being blocked by sessions imported under another job
+- Navbar compression for split-screen usage:
+  - Reworked top navigation to reduce horizontal pressure without forced full collapse
+  - Moved admin-only links into `Admin` dropdown
+  - Added `More` dropdown for secondary non-admin navigation links
+  - Kept primary daily operational link (`Run Checks`) directly visible
+  - Adjusted role-specific visibility: Viewer now has `Customers` and `Jobs` directly visible in navbar
+
+### Added
+- Microsoft Entra SSO implementation (branch `v20260223-07-entra-sso`):
+  - Authorization code flow routes:
+    - `GET /auth/entra/login`
+    - `GET /auth/entra/callback`
+  - Entra-aware logout flow (redirects through Entra logout endpoint when applicable)
+  - Login page support for "Sign in with Microsoft" button when SSO is configured/enabled
+  - Settings-backed Entra configuration fields in `SystemSettings` + migration support:
+    - `entra_sso_enabled`
+    - `entra_tenant_id`
+    - `entra_client_id`
+    - `entra_client_secret`
+    - `entra_redirect_uri`
+    - `entra_allowed_domain`
+    - `entra_allowed_group_ids`
+    - `entra_auto_provision_users`
+  - Optional local auto-provisioning of unknown Entra users as Viewer
+  - Security-group gate for SSO:
+    - allowlist by Entra Group Object IDs
+    - login blocked when token lacks required group context or group overage prevents reliable evaluation
+- Documentation updates for Entra SSO:
+  - Added page `documentation/settings/entra-sso`
+  - Added navigation entry under Settings
+  - Marked explicitly as **Untested in Backupchecks**
+  - Included setup instructions for tenant/client/secret/redirect, group-based access, and troubleshooting

+
+### Status
+- Implemented but marked **Untested in Backupchecks**.
+
+### Routes
+- `GET /auth/entra/login` – starts Entra auth code flow.
+- `GET /auth/entra/callback` – exchanges code, maps/provisions local user, logs in session.
+- `/auth/logout` – Entra-aware logout redirect when user authenticated via Entra.
+
+### Access Controls
+- Optional tenant/domain restriction (`entra_allowed_domain`).
+- Optional Entra security-group allowlist (`entra_allowed_group_ids`) based on group object IDs.
+- Group overage / missing groups claim blocks login intentionally when group gate is enabled.
+
+### Local User Mapping
+- Primary mapping by `preferred_username`/UPN/email.
+- Optional auto-provision (`entra_auto_provision_users`) creates local Viewer users for unknown identities.
+
+### Documentation
+- Built-in docs page: `/documentation/settings/entra-sso`
+- Includes configuration steps and explicit untested warning.

+## Navbar Notes (Latest)
+
+- To reduce split-screen overflow, nav is compacted by grouping:
+  - admin-only links under `Admin` dropdown
+  - secondary non-admin links under `More` dropdown
+- Primary operational links remain visible (notably `Run Checks`).
+- Viewer role now exposes `Customers` and `Jobs` directly in navbar.

    - Resolution tracked via matching internal ticket's `resolved_at` field
    - **Auto-propagation**: Linked to new runs via two-strategy approach
