RigDoctor — Module Catalog (DRAFT v0.2)

Status: ⬜ not started · 🟦 designing · 🟨 in progress · ✅ done

Module set per D14, plus M12 (session sharing, D16) and M13 (auto-update, D18). M7 (stress/repro) was dropped (D7). M10/M11 are the GUI and tray modules (D10/D11). GPU scope reads "all (NVIDIA first)" — NVIDIA first, others via the vendor abstraction (D4).

Notes per module

• M1 Sensor core — the foundation everything else samples from. Stdlib-only. Abstracts NVIDIA/AMD/Intel + hwmon behind one interface; ship the NVIDIA + hwmon path first.
• M3 Crash-capture logger — the highest-value piece for the seed use case. fsync per sample; GPU-lost detection via query timeout; bounded rotation; systemd --user service with a user-selectable trigger mode (always-on / game-launch / manual — D6). Implemented (manual trigger): JSONL log with fsync-per-sample, size-based rotation (log_max_bytes/log_backups), GPU-lost/recovered event markers, atomic status file, and rigdoctor record run|start|stop|status|report. The foreground run is the systemd-ready entrypoint; the service unit + always-on/game-launch triggers (D6/D12) land in Phase 4. Also fully driven from the GUI's Recording/Logs page (M10) via shared core.reccontrol.
• M4 Health report — turns scattered logs into a prioritized, plain-language findings list with suggested fixes (read-only, D9). Reuses M1 for a live snapshot. Also powers the guided diagnostic session (with M3): pick a game → focused capture → scan → findings (see SPEC §4). Implemented: journalctl scan (Xid/panic/OOM/MCE/AER/thermal/amdgpu), SMART, NVIDIA driver-mismatch, journald-persistence + live-temp checks; rigdoctor report (text/JSON) + GUI Health tab. GPU-firmware verification deferred.
• M2 Live monitor — depends on M1; the terminal "HWMonitor for Linux" face. Stdlib-only.
• M5 / M6 Diagnostics — inventory export + gaming-env checks; M6 flags risky settings and suggests the fix command but does not apply it (D9).
• M8 Alerting — threshold/event notifications; integrates with the tray applet (M11).
• M10 Desktop GUI — PySide6 graphical front-end over the core engine (dashboard, log browser, report viewer, logger controls). Optional; adds the Qt dependency. Bootstrapped early (ahead of its Phase 4 slot) at the user's request: dark-themed window with sidebar nav, a live dashboard (circular gauges + collapsible per-subsystem cards, temperature- colored values), and a Recording/Logs page with full M3 controls (start/stop/status + post-crash report). Health/Inventory remain placeholders until M4/M5. GUI-first per D17.
• M11 Tray applet — QSystemTrayIcon menu-bar applet. Dropdown shows live M1 readouts (CPU temp, GPU temp, memory used/total, status dot) and is led by a Run Diagnostic action (the guided diagnostic session), plus Open dashboard / Start-Stop recording / Snapshot / Quit (D13). Optional; shares the Qt dependency with M10.
• M9 Installer — interactive wizard layered on the .deb (D8); apt-first dependency resolution; enables the logger service and trigger mode. Implemented (first cut): distro/ package-manager/GPU detection (core/sysenv), an optional-component catalog (core/catalog), and dependency install via pkexec/sudo — rigdoctor install [--check] [-y] + GUI Setup tab. Pending: writing config/module selection and enabling the systemd --user service.
• M12 Session sharing / remote assist (D16) — let a helper inspect a user's machine, in an escalating ladder: (1) diagnostic bundle export (inventory + recent log + report, one-way), (2) live read-only view over a user-chosen tunnel (Tailscale/cloudflared/SSH, no hosted relay), (3) gated interactive terminal wrapping tmate/sshx (read-only by default; read-write only on explicit consent — a deliberate exception to D9). Per-session consent, ephemeral revocable tokens, audit log.
• M13 Auto-update (D18) — check half implemented: on GUI launch, core/updates queries the Gitea releases API and the sidebar shows up-to-date / an "Update to v…" button / "update check unavailable" (the instance currently requires sign-in for anonymous API calls). The no-root self-update (download → verify → atomic swap → restart) is still pending. Original plan: On launch, check the public Gitea releases API and self-update a user-local install with no root (download → verify checksum/signature → atomic symlink swap → restart, incl. the daemon). HTTPS-only, version-check-only (no telemetry), opt-out-able. Surfaced in the GUI; rigdoctor update in the CLI. (.deb users update via apt instead.)

Bundles (final — D14)

• Essential: M1 + M3 + M4 (the MVP, NVIDIA-only — D5)
• Monitoring: M2 + M8
• Diagnostics: M5 + M6
• Desktop UI: M10 + M11 (adds PySide6)
• Sharing: M12 (session sharing / remote assist — D16)

MVP candidate — confirmed (D5)

M1 + M3 + M4 (Essential), NVIDIA-only, CLI-first. Gives a working tool that captures the GPU crash and explains the logs — deliverable before the installer, GUI/tray, or multi-vendor work.
