 ## [Unreleased]
 
+## [0.3.7] - 2026-09-16
+
+### Changed
+
+- Make usage-history axes, units, UTC boundaries, active 7/14/30/90-day window, gaps, partial periods, stacked write attribution, and hourly drill-down explicit; keep live graph data refreshed on the existing five-minute cadence.
+
+## [0.3.6] - 2026-09-16
+
+### Changed
+
+- Use sentence case throughout the dashboard and add persistent keyboard and sudo guidance.
+- Share read-only status acquisition between the CLI and TUI, preserving unknown monitoring state and store-fault recovery guidance.
+- Use one authenticated action path for the CLI and TUI; let valid collection runs finish without the former 30-second dashboard cutoff.
+- Remove the unused sparkline and habit-bar rendering path while retaining the interactive history graph.
+- Align all package formats on the MIT license and Python 3.10 minimum; include the license text in native packages.

+### Fixed
+
+- Correct observation-store directory permissions in native packages, including repair of older runit installations during upgrade.

+### Void Linux (XBPS)
+
+Void x86_64 with glibc and runit is the native target. Its signed XBPS channel
+is available from the permanent repository below. Add it, refresh its
+metadata, and install the released package:
+
+```bash
+sudo install -d -m 0755 /etc/xbps.d
+echo 'repository=https://git.bongbetic.com/xavierk/Fenris-xbps/raw/branch/stable/x86_64' \
+  | sudo tee /etc/xbps.d/fenris.conf
+sudo xbps-install -M -S fenris
+```
+
+XBPS requires remote repositories to be signed. On the first refresh it
+displays the repository signing key embedded in the signed metadata; accept it
+only when its RSA SHA256 fingerprint is
+`SHA256:AvPMRlKMikPg75u0iKr8AUkxlfU/Ad4k/S4o2M9W4/w`. The public key is also
+available at
+`https://git.bongbetic.com/xavierk/Fenris-xbps/raw/branch/stable/keys/fenris-xbps-signing.pub`.
+For later updates, always refresh first so XBPS fetches the current index:
+
+```bash
+sudo xbps-install -M -Syu
+```
+
+The `-M` flag bypasses XBPS's on-disk repodata cache. It is required when
+checking for a newly published package through Gitea's cached raw-file URL.
+
+The runit service remains dormant after installation. `fenris monitor resume`
+creates `/var/service/fenris-collect`; pause removes that link and records a
+deliberate disable in the observation history.
+
+Fenris keeps the observation store root-written and readable by the `fenris`
+group. Add each TUI user to that group, then start a new login session before
+running Fenris:
+

+sudo usermod -aG fenris "$USER"

 ## Reading the dashboard
 
-`fenris` opens the TUI dashboard.
+Run `fenris` as your normal user to open the TUI dashboard. The dashboard does
+not need `sudo`. Use `sudo` for package installation and system configuration;
+pause, resume, and collect-now actions normally authenticate through polkit.
+
+If the observation store is inaccessible, add your login user to the `fenris`
+group with `sudo usermod -aG fenris "$USER"`, then log out and back in.
+
+If polkit authentication is unavailable, quit the dashboard and run only the
+required administrative action in your terminal:
+
+```bash
+sudo fenris monitor resume   # Enable monitoring now and across reboots
+sudo fenris monitor pause    # Confirm a deliberate monitoring pause
+sudo fenris sample           # Request one collection run
+```
+
+Reopen the dashboard with `fenris` afterward. Press `?` for these instructions
+and keyboard controls at any time; use the arrow keys to scroll and `Esc` to close.
+
+The CLI and TUI share the same authenticated action path. Authentication and
+waiting for collection have no separate dashboard deadline; the native collector
+enforces its 90-second runtime limit. An interrupted or failed action is not
+automatically retried—check `fenris status` before retrying.
 
 - **Continuity** — the service strip's continuity line (and `fenris status`) reports whether monitoring survives reboots: `monitoring: active in background · persists across reboots`, or `monitoring: does not start on next boot`.
 - **Paused vs. quit** — a full-width `monitoring: paused — deliberate disable` block means collection is stopped (`fenris monitor pause`); resume with `fenris monitor resume`. Pressing `q` only leaves the screen — monitoring keeps running in the background.
-- **Auth banner** — at launch, `privileged actions will prompt for authentication (polkit)` shows once and clears on the first refresh. Privileged actions elevate via polkit; Fenris never asks for sudo.
+- **Auth banner** — the launch notice explains normal-user startup and polkit authentication, then clears on the first refresh. The `?` help screen remains available.

 # 8. Native Void Linux support and XBPS delivery
 
-Status: Accepted scope and hosting direction; implementation and acceptance proof pending.
+Status: Accepted — implementation and host acceptance completed; evidence is recorded in [issue #87](https://git.bongbetic.com/xavierk/Fenris/issues/87).
 
 Fenris will support Void Linux natively with runit and full application feature parity, while retaining its existing Debian/RPM and systemd support. This extends the platform boundary in [ADR 0003](0003-service-lifecycle-and-sanctioned-toggle.md) and the delivery scope in [ADR 0007](0007-package-delivery-amends-0004.md): requiring Void users to replace their init system would not meet the native-support goal.
 
 Delivery will include a Fenris-maintained, signed XBPS repository that users configure once for subsequent installation and updates through XBPS, plus versioned release artifacts and notes on Gitea. All downloads must be served directly by Gitea itself; a separate static HTTP repository, even alongside Gitea, does not satisfy this requirement.
 
-Use a dedicated public Gitea repository, provisionally `xavierk/Fenris-xbps`, with a permanent `stable` branch. Its raw-file URL serves the XBPS index, versioned packages, and package signatures as ordinary Git blobs without LFS. Keeping binaries in a separate repository avoids increasing application source-clone size. This accepts growth in distribution-repository Git history in exchange for publishing index and artifacts together through one branch update, without the generic registry's delete-and-upload index replacement gap. The proposed repository has not yet been created.

Verify binary delivery limits and index freshness: the inspected Gitea raw endpoint advertised six-hour HTTP caching, so immediate update visibility has not been established.
+Serialize publication, commit the signed index and its new artifacts together, and retain older versioned artifacts in the current tree so clients with cached older indexes can still download them. Native XBPS installation and update tests against the actual endpoint are required before release validation. The first release acceptance recorded in issue #87 verified direct artifact delivery, signed metadata, retained packages, and immediate discovery after an explicit memory-synchronized refresh. The Gitea raw endpoint advertises six-hour HTTP caching; users should use `xbps-install -M -S` when looking for updates so XBPS bypasses its on-disk repodata cache.
 
 Immediate availability is required: after successful XBPS publication, an explicit repository refresh against the permanent URL must discover the newly published version without a cache-expiry wait or a URL change. This does not promise automatic installation on client machines. Acceptance must exercise a client that fetched the previous index before publication and verify that refresh retrieves the new index and its signed package afterward. Resolve and document actual client and intermediary cache behavior; if the selected Gitea route cannot meet this requirement, hold XBPS publication and revisit its delivery mechanics rather than silently accepting delayed availability.

Current host inspection found Void x86_64/glibc with runit, polkit support and an NVMe controller; Fenris and smartmontools were absent. Verify these facts again before host changes.
