# Changelog

<!--
Maintainers add one user-facing entry to Unreleased with each change. A release
commit bumps pyproject.toml, renames Unreleased to that bare-semver version and
an ISO date, then restores an empty Unreleased section; tag that commit. Do not
backfill releases from before this changelog.

## [Unreleased]

## [0.5.0] - 2026-09-19

### Changed

- Make drive activity the focus of a Chalktone dashboard with Live, Day, and History tabs, panel zoom, and fixed monitoring controls.
- Replace block bars with labelled dotted volume plots that fit the terminal and preserve gaps, partial evidence, and point inspection.

### Fixed

- Preserve historical selections and store-fault messages through graph refresh and resize.
- Show hourly drill-down results without overwriting them with a loading placeholder.
- Keep known unallocated daily volume visible across coverage gaps, and distinguish missing hourly evidence from zero on small terminals.

## [0.4.0] - 2026-09-18

### Added

- Show local-day read and write totals with their recorded timezone, labelled as totals so far for the current day.
- Open the dashboard on a live three-hour written-volume graph with a read/write toggle and selected-point inspection.
- Browse history by day from the keyboard with `[`, `]`, `g` date entry, and `t` for today and the live view.

### Changed

- Collect every three minutes on systemd and runit, plot live points at their actual timestamps, and retain three-minute detail for 14 days before durable summaries.
- Withhold the endurance outlook until one full local observation day has usable evidence, then show it with categorical confidence.

### Fixed

- Keep midnight-spanning activity once as shared boundary evidence instead of adding it to both days.
- Publish derived hour and day history consistently with each collection run.

## [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 current three-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.

## [0.3.5] - 2026-09-14

### Added

- Show trustworthy first-use history, qualifying-day progress, and confidence in the dashboard.
- Add an interactive daily-writes graph with hourly drill-down and evidence-anchored scenario windows.
- Repair retained observation history safely and keep its retention state visible.
- Present a unified monitoring status, drive-health context, and Fenris identity in the dashboard.
- Remember accessible colour and motion preferences and keep the dashboard usable at constrained terminal sizes.

## [0.3.4] - 2026-09-10

### Added

- Add Fenris identity and a polkit authentication notice to the dashboard.
- Clarify monitoring continuity, deliberate pauses, and quitting in the dashboard and status output.
- Add per-release notes with installation, verification, and rollback guidance.
