CHANGELOG.md

@@ -5,6 +5,34 @@ 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).
 
+## [0.36.1] - 2026-05-22
+### Fixed
+- `rigdoctor gui` printed the wrong fix when PySide6 is missing — it suggested the non-existent
+  `python3-pyside6` package. Now it names the real split modules
+  (`python3-pyside6.qt{widgets,gui,websockets,svg}` + `python3-pyte`).
+
+## [0.36.0] - 2026-05-22
+### Fixed
+- **`.deb` now installs all dependencies automatically — no manual tool install.** The previous
+  `Recommends: python3-pyside6` named a package that doesn't exist on Debian/Ubuntu (PySide6 is
+  split per module), so apt silently skipped it and the GUI wouldn't start. Now it Recommends the
+  actual modules the GUI imports — `python3-pyside6.qt{widgets,gui,websockets,svg}` + `python3-pyte`.
+### Changed
+- **`apt install rigdoctor` sets up the whole toolset.** The `.deb` also Recommends the optional
+  diagnostic/gaming tools (smartmontools, lm-sensors, dmidecode, pciutils, libnotify-bin,
+  libsecret-tools, gamemode, mangohud) so they install by default — users never hand-install
+  tools. `cpupower` is a Suggests (kernel-tied); `--no-install-recommends` still gives CLI-only.
+
+## [0.35.0] - 2026-05-22
+### Added
+- **`.deb` package (M9 / D8)** — `packaging/make_deb.py` builds a `rigdoctor_<version>_all.deb`
+  (pure-Python, `Architecture: all`) via `dpkg-deb`: `Depends: python3`, with the GUI deps
+  (`python3-pyside6`, `python3-pyte`) as **Recommends** so `sudo apt install ./rigdoctor_*.deb`
+  gives the full app and `--no-install-recommends` gives CLI-only. Installs the package, both
+  launchers, the desktop entry, and the icon. CI (`release.yml`) builds it as a **release asset**
+  every release, and optionally publishes it to the Gitea **apt registry** (set a `REGISTRY_TOKEN`
+  secret) for `sudo apt install rigdoctor`. **M9 is now complete.**

 # RigDoctor
 
-A **modular diagnostics, monitoring, and health-check toolkit for Linux gamers.**
+**Hardware monitoring & crash diagnostics for Linux gamers.** Live sensors, crash-safe
+logging, plain-language health reports, per-game diagnostics, and optional AI explanations —
+in a desktop app, a tray applet, or the terminal. Ubuntu/Debian + NVIDIA first.
 
-> **Status:** 🟢 Phase 1 (MVP) complete. The **sensor core (M1)**, **crash-capture logger
-> (M3)**, and **health report (M4)** all work — live `snapshot`/`monitor`, crash-safe `record`
-> with a post-crash report, and `report` to scan logs/SMART/driver for likely causes. A
-> desktop GUI (M10) ties them together (dashboard, recording, health). See `docs/ROADMAP.md`.
+Linux gaming faults are hard to pin down — GPUs falling off the PCIe bus, black screens
+mid-game, silent thermal/VRAM throttling, driver/Proton mismatches. The useful data is
+scattered across `nvidia-smi`, `/sys`, `journalctl`, and SMART, and the readings right before a
+freeze are usually lost. RigDoctor pulls it together and keeps the evidence.
 
-## Why this exists
+## Features
 
-Linux gaming hardware faults are hard to diagnose: GPUs falling off the PCIe bus, the screen
-suddenly going black mid-game, silent thermal/VRAM throttling, power transients,
-driver/library mismatches, Proton quirks, and CPU governor / power-profile misconfiguration.
-The data needed to diagnose them is scattered across `nvidia-smi`, `/sys/class/hwmon`,
-`journalctl`, SMART, and more — and the most useful readings (the ones right before a hard
-freeze) are usually lost because nothing flushed them to disk.
+- **Live monitoring** — a dark desktop **dashboard** (history graphs + per-subsystem cards), a
+  **tray applet** with at-a-glance status, and a terminal view (`rigdoctor monitor`).
+- **Crash-safe recording** — background logger that `fsync`s every sample, so the state right
+  before a hard freeze survives. Manual, always-on, or auto-start when a game launches.
+- **Health report** — scans `journalctl`/SMART/driver for likely causes (Xid, OOM, disk
+  errors, throttling…) and explains them with suggested fixes.
+- **Per-game diagnostics** — pick a game, capture while you play, get a focused report; hard
+  crashes are detected and analysed on next launch.
+- **Gaming tune-ups** — flags risky settings (CPU governor, PCIe ASPM, persistence mode…) with
+  **one-click, reversible fixes**.
+- **Proactive alerts** — desktop notifications on overheating and critical kernel events
+  (GPU-lost, Xid, out-of-memory, disk I/O).
+- **AI explanations** *(optional, opt-in)* — explain a diagnostic in plain language with a
+  **local model (Ollama)** or **Claude**. Never automatic; only when you press the button.
+- **Shareable reports** — zip a diagnostic (logs, inventory, AI transcript) to hand to someone,
+  or share a live **terminal session** for remote help.
+- **Self-updating** — `apt upgrade`, or the in-app updater.
 
-RigDoctor pulls all of that into one modular tool: live monitoring, crash-safe logging, a
-one-shot health report, and an interactive installer that only sets up the modules a given
-user actually needs for their hardware.
+## Install
 
-**Seed use cases:** an RTX 3070 that intermittently "falls off the bus" under heavy GPU load
-(Path of Exile on Linux, Escape from Tarkov on Windows), and a monitor going black mid-game.
-See `docs/SPEC.md` §1.
+### Debian / Ubuntu — `.deb`
 
-## How you run it
-
-RigDoctor is **GUI-first** — the desktop app is the primary way in — but every feature is
-also available headless:
-- **Desktop GUI** — graphical dashboard, recording controls, log browser, reports. The
-  default interface for most users.
-- **Tray applet** — a small top-menu-bar applet with quick actions and at-a-glance status.
-- **CLI** — full functionality from the terminal; works over SSH and in scripts.
-
-The GUI/tray are optional modules; a headless (CLI-only) install loses no capability.
-
-## Key decisions (settled)
-
-| Topic | Decision |
-|-------|----------|
-| Name | **RigDoctor** |
-| Language / stack | **Python 3 + Qt (PySide6)** — core/CLI/daemon stdlib-only; Qt only for GUI/tray |
-| Primary distro | **Ubuntu** (Debian via apt); others best-effort later |
-| Primary GPU | **NVIDIA** first; AMD, then Intel later |
-| MVP | **Sensor core + crash logger + health report** (NVIDIA-only, CLI-first) |
-| Distribution | **User-local install** (self-updating from the public repo, no root); **`.deb`** optional |
-| Scope of action | **Read-only + suggestions** (no auto-apply yet) |
-| Stress tests | **Out of scope** |
-
-Full rationale and the still-open questions are in `docs/DECISIONS.md`.
-
-## Repo layout
-
-| Path | Purpose |
-|------|---------|
-| `docs/SPEC.md` | Product specification — vision, requirements, modules (the main planning doc) |
-| `docs/ARCHITECTURE.md` | Technical design — core engine, front-ends, daemon, installer |
-| `docs/MODULES.md` | Catalog of modules with scope, dependencies, status |
-| `docs/ROADMAP.md` | Phased milestones |
-| `docs/DECISIONS.md` | Decision log + remaining open questions |
-| `src/rigdoctor/` | Source code — `core/` engine + sources, `cli.py`, `render.py` |
-| `installer/` | Installer / `.deb` packaging (empty until Phase 4) |
-| `tests/` | Tests (stdlib `unittest`) |
-
-## Install (user-local, no root)
-
-RigDoctor installs into a private venv under `~/.local` — no root, self-updating:
+The simplest path: grab the latest **`rigdoctor_<version>_all.deb`** from the
+[releases page](https://git.jesseyvanofferen.com/jessey/rigdoctor/releases) and install it —
+apt pulls the GUI dependencies (PySide6, pyte) automatically:
 
 ```bash
-./install.sh                 # from a source checkout or the self-extracting .run
-./install.sh --ref v0.0.6    # install a specific released tag (needs a token)
-./install.sh --uninstall     # remove it
+sudo apt install ./rigdoctor_*_all.deb        # CLI only: add --no-install-recommends
 ```
 
-This adds `rigdoctor` / `rigdoctor-gui` to `~/.local/bin` and a desktop entry. Each release
-also ships a one-file **`.run`** installer (download, `chmod +x`, run). Updates are gated to
-accounts on the Git server (a Personal Access Token); save one via the GUI **Setup → Update
-access** panel or `rigdoctor login`, then `rigdoctor update` (or the sidebar button).
-
-## Run it (dev)
-
-Stdlib-only, no install needed (target is Python ≥ 3.11; tested on 3.14):
+**Or add the apt repository** for `apt install` + automatic updates. The registry is private and
+GPG-signed, so you need a Gitea token with **`read:package`**, the signing key, and the deb822
+source (`read -rsp` keeps the token out of your shell history):
 
 ```bash
-PYTHONPATH=src python3 -m rigdoctor snapshot     # one-shot sensor read
-PYTHONPATH=src python3 -m rigdoctor snapshot --json
-PYTHONPATH=src python3 -m rigdoctor monitor -n 1 # live view (Ctrl-C to quit)
-PYTHONPATH=src python3 -m rigdoctor sources       # list detected sensor sources
-PYTHONPATH=src python3 -m unittest discover -s tests
+read -rsp 'Gitea read:package token: ' TOKEN; echo
+
+# signing key → dearmored into the keyring (the key endpoint requires the token too)
+sudo install -d -m 0755 /etc/apt/keyrings
+curl -fsSL --user <user>:"$TOKEN" \
+  https://git.jesseyvanofferen.com/api/packages/jessey/debian/repository.key \
+  | sudo gpg --dearmor -o /etc/apt/keyrings/gitea-jessey.gpg
+
+# download credentials, kept out of the sources file
+printf 'machine git.jesseyvanofferen.com login <user> password %s\n' "$TOKEN" \
+  | sudo tee /etc/apt/auth.conf.d/rigdoctor.conf >/dev/null
+sudo chmod 0600 /etc/apt/auth.conf.d/rigdoctor.conf
+
+# the source (modern deb822 format, GPG-verified, all-arch)
+sudo tee /etc/apt/sources.list.d/rigdoctor.sources >/dev/null <<'EOF'
+Types: deb
+URIs: https://git.jesseyvanofferen.com/api/packages/jessey/debian
+Suites: stable
+Components: main
+Architectures: all
+Signed-By: /etc/apt/keyrings/gitea-jessey.gpg
+EOF
+
+sudo apt update && sudo apt install rigdoctor
 ```
 
-### Crash-capture logger (M3)
+Then `sudo apt upgrade` keeps it current. *(Quick-and-dirty alternative if the registry isn't
+signed: skip the key and use a one-line `deb [arch=all trusted=yes] …/debian stable main` source.)*
 
-A crash-safe background logger (JSONL, `fsync` per sample, bounded by rotation) for catching
-the state right before a freeze:
+### Any distro — self-extracting `.run` (no root)
+
+Download **`rigdoctor-<version>-installer.run`** from the releases page and run it. It installs
+into a private virtualenv under `~/.local` (no root), adds the launchers + desktop entry, and
+opens the first-run setup wizard:
 
 ```bash
-rigdoctor record start          # start logging in the background
-rigdoctor record status         # is it running? latest readings, sample count
-rigdoctor record stop           # stop it
-rigdoctor record report         # post-crash summary: peaks, events, last samples
-rigdoctor record run            # run in the foreground (the systemd-ready entrypoint)
+sh rigdoctor-*-installer.run
 ```
 
-Logs live in `~/.local/share/rigdoctor/logs/`. It detects GPU "lost"/hang (nvidia-smi query
-timeout) and writes an event marker. Trigger modes (always-on / game-launch) and the
-`systemd --user` service arrive in Phase 4.
+### Updating & removing
 
-### Desktop GUI (M10)
+- **`.deb`:** `sudo apt upgrade` (or reinstall a newer `.deb`).
+- **`.run` / user-local:** the in-app **Update** button, or `rigdoctor update`.
+- **Remove:** `sudo apt remove rigdoctor`, or `rigdoctor uninstall` for the user-local install.
 
-The GUI uses PySide6 (Qt) — the only part of RigDoctor that needs a non-stdlib dep:
+## Using it
+
+Launch **RigDoctor** from your app menu, or:
 
 ```bash
-pip install -e '.[gui]'   # core + PySide6, gives `rigdoctor` and `rigdoctor-gui`
-rigdoctor gui             # or: rigdoctor-gui
+rigdoctor-gui          # desktop app (+ tray)
+rigdoctor --help       # everything from the terminal (works over SSH)
 ```
 
-It opens a dark-themed window with sidebar navigation and a **live dashboard** over the
-same sensor core — circular gauges for the headline metrics plus collapsible per-subsystem
-cards (GPU/CPU/memory/storage) with temperature-colored values (icey-blue → green → red).
-The **Logs** and **Health** sections are full pages (recording controls + post-crash report;
-and the kernel-log / SMART / driver scan). **Inventory** is a placeholder until M5 lands.
+Handy CLI commands:
 
-Without the GUI extra, `pip install -e .` gives just the stdlib-only CLI.
+```bash
+rigdoctor snapshot              # one-shot reading of every sensor
+rigdoctor monitor              # live terminal dashboard
+rigdoctor report               # health report (logs / SMART / driver)
+rigdoctor diagnose start|finish # capture while gaming, then analyse
+rigdoctor gameenv              # flag risky gaming settings + fixes
+rigdoctor inventory            # hardware/OS inventory
+rigdoctor ai explain           # AI explanation of the current findings (opt-in)
+rigdoctor bundle               # zip the latest diagnostic into a shareable report
+```
 
-## Start here
+## Requirements
 
-1. Read `docs/SPEC.md` for what we're building.
-2. Read `docs/ROADMAP.md` for the build order (Phase 1 = the MVP).
-3. Read `docs/DECISIONS.md` for the settled decisions (D1–D15).

+- **Linux** — Ubuntu/Debian first-class (the `.deb`); the `.run` works on any distro with
+  Python ≥ 3.11.
+- **GPU** — NVIDIA fully supported (via `nvidia-smi`); AMD/Intel sensors are best-effort.
+- **CLI/daemon** need only Python 3 (stdlib). The **GUI/tray** add **PySide6** (`python3-pyside6`).
+- Optional tools unlock more: `smartmontools`, `lm-sensors`, `gamemode`, `mangohud`. The setup
+  wizard offers to install them.
+
+## Privacy
+
+Everything stays on your machine — no telemetry, no phone-home. The AI assistant is **off by
+default** and runs only when you explicitly trigger it; with Ollama nothing leaves the machine,
+and the Claude option asks before sending. Reports are local files; they leave only if you share
+the zip.
+
+## Development
+
+RigDoctor's core is stdlib-only Python; the GUI/tray use PySide6.
+
+```bash
+git clone https://git.jesseyvanofferen.com/jessey/rigdoctor && cd rigdoctor
+pip install -e ".[gui]"                    # core + GUI; omit [gui] for CLI-only
+python -m unittest discover -s tests       # run the test suite
+PYTHONPATH=src python3 -m rigdoctor snapshot   # run without installing
+```
+
+Design docs live in `docs/` — `SPEC.md` (vision/requirements), `ARCHITECTURE.md`,
+`MODULES.md` (module catalog), `ROADMAP.md`, and `DECISIONS.md` (the decision log).
+Contributions: branch off `main`, keep tests green (CI runs them on PRs), and bump the version
++ `CHANGELOG.md` for shipped changes.
