Merge pull request 'fix(gui): correct relative import that broke app startup — 0.18.2' (#14) from feat/m6-steam-detection into main

Reviewed-on: #14

CHANGELOG.md

@@ -5,6 +5,79 @@ All notable changes to RigDoctor are recorded here. Format follows
 (`MAJOR.MINOR.PATCH`, pre-1.0). `__version__` and `pyproject.toml` must match the git
 release tag (so the auto-updater, D18, can compare versions).
 
+## [0.18.2] - 2026-05-22
+### Fixed
+- **GUI wouldn't start** (0.18.0 regression): the recording indicator used a wrong relative
+  import (`from .core` → `rigdoctor.gui.core`, which doesn't exist), crashing `MainWindow` on
+  launch. Corrected to `from ..core`.
+
+## [0.18.1] - 2026-05-22
+### Changed
+- Recording badge: dropped the sample count (not useful at a glance) — it now shows just
+  **● Recording** + the game, plus a **⚠ GPU-lost** line if one is detected.
+
+## [0.18.0] - 2026-05-22
+### Added
+- **Global recording indicator.** While a capture is running, the sidebar shows a red
+  **● Recording** badge on every page — with the **game** being captured and the live sample
+  count (and a GPU-lost flag if seen). It polls the recorder, so it reflects captures started
+  any way: manual `record`, a guided diagnostic, or the Steam launch wrapper.
+
+## [0.17.0] - 2026-05-22
+### Added
+- **Inventory page is back in the GUI** (it was removed in 0.7.2 in favor of the CLI). Sidebar
+  **Inventory** → System / CPU / Firmware / Memory / GPU / Storage / Display as cards, with
+  **Copy Markdown** and **Save…** for pasting into forum/bug reports, and **Refresh**. Root-only
+  details (motherboard/BIOS/RAM modules via dmidecode) fill in after the launch password prompt.
+  Backed by the existing M5 `core/inventory.py` — the CLI `rigdoctor inventory` is unchanged.
+
+## [0.16.0] - 2026-05-22
+### Added
+- **Automatic crash-capture via a Steam launch wrapper (M6/D12).** Set `rigdoctor wrap
+  %command%` as a game's Steam launch option (or in Lutris/Heroic's wrapper field) and RigDoctor
+  starts a focused, game-tagged capture when the game launches and stops it cleanly on exit — no
+  manual Run Diagnostic / Finish. A hard freeze leaves the capture unterminated, so it's flagged
+  as a crash next launch. The wrapper resolves the game name from Steam's `SteamAppId`, doesn't
+  disturb an existing capture, and returns the game's exit code. (`core/wrap.py`, `rigdoctor wrap`.)
+- GUI **Auto-capture…** helper on the Games page: shows the exact launch-option line (absolute
+  path, copy button) and how to set it in Steam.
+- Auto-capture preserves an unanalyzed crash (`diagnostic-crash.jsonl`) before starting a new
+  capture, so relaunching the game can't wipe a crash report you haven't seen yet.
+### Fixed
+- `docs/MODULES.md` status column was stale — M1, M3, M4, M5, M8, M10, and M13 are done and now
+  marked ✅ (only M2 and M11 remain not-started; M6/M9/M12 in progress).
+
+## [0.15.0] - 2026-05-22
+### Added
+- **Hard-crash detection & recovery for the guided diagnostic.** If a focused capture ends
+  without a clean stop (the recorder never wrote `session-stop` and isn't running), RigDoctor
+  treats it as a likely hard freeze. On launch the **Games** page shows a warning banner —
+  *"Your last diagnostic for <game> ended unexpectedly…"* — with **Analyze crash** / **Dismiss**.
+- **Deeper crash analysis.** *Analyze crash* combines the captured window (final readings before
+  the freeze + any GPU-lost event) with a focused scan of the **previous (crashed) boot's kernel
+  log** (`journalctl -k -b -1`: Xid/panic/OOM/MCE/AER/thermal) plus SMART/driver/persistence/
+  live-temp checks — the full "what happened" picture. `core/diagnostic.py` gains
+  `pending_crash()` / `analyze_crash()`; `health.check_previous_boot()` +
+  `run_health_checks(include_journal=False)` back it.
+
+## [0.14.0] - 2026-05-22
+### Changed
+- **Dashboard headline tiles are now history trend graphs** instead of single-value gauges —
+  GPU temp, GPU load, CPU temp, and memory each plot their recent history (with the current
+  value, window min/max, and a dashed warning-threshold line), so you can see changes over time
+  rather than only the instantaneous reading. New `HistoryGraph` widget (QPainter, no new deps).
+
+## [0.13.0] - 2026-05-22
+### Added
+- **Run Diagnostic now explains itself and can launch the game.** Clicking Run Diagnostic shows
+  what to do — *play the game, reproduce the crash, then Finish & analyze* (and that data
+  survives a hard freeze + reboot) — and offers **Launch game & start** (asks Steam to run it by
+  appid) or **Start without launching**. The recording banner now spells out the next step
+  instead of just showing a sample count.
+### Fixed
+- Button labels containing "&" (e.g. "Finish & analyze") rendered as "Finish _analyze" because
+  Qt treated the "&" as a keyboard mnemonic — now escaped so the ampersand shows literally.
+
 ## [0.12.0] - 2026-05-22
 ### Added
 - **Guided diagnostic in the GUI.** Each game on the **Games** page now has a **Run Diagnostic**
