+
+## 1. PROJECT OVERVIEW
+
+**Sysadmin Chronicles** is a native Linux-only game where the player works as a
+junior sysadmin at Axiom Works, handling tickets inside **real Linux virtual
+machines** managed by **QEMU/KVM via libvirt**.
+
+The runtime stack (as of v4.0):
+- **Game server** — Node.js / Express + WebSocket (`server/`). Owns all game
+  logic: quest state, trust, validation, VM lifecycle, incidents, save state.
+- **Web HUD** — Svelte single-page app (`frontend/`). Tickets, mail, Sage, docs,
+  trust bar. Served from the game server at `http://192.168.100.1:3000`.
+- **Workstation VM** — XFCE desktop (Debian 12, sc-workstation). Player's desk.
+  Chromium auto-opens the HUD. Tilix provides a real terminal for SSH to target VMs.
+- **Target VMs** — Headless Debian (hermes) and Arch (vulcan). Quest objectives
+  live here. Player investigates and fixes via SSH from the workstation terminal.
+
+The player experience:
+- Sits at the workstation VM (via SPICE/remote-viewer fullscreen on the host)
+- Reads tickets and mail in the Chromium HUD
+- Opens Tilix, SSHes to hermes or vulcan, fixes real problems
+- Clicks "Mark Complete" in the HUD — game server SSHes in and validates VM state
+- World reacts, trust shifts, new mail arrives via WebSocket push
+
+No simulated terminal. No fake SSH sessions.
+
+---
+
+## 2. CORE DESIGN PRINCIPLES
+
+- Realism over simulation
+- Native Linux execution only
+- CLI-first development and asset wiring
+- Minimal, stable scenes; behavior lives in scripts
+- Data-driven content for quests, tickets, incidents, and dialogue
+- State-based validation only; never command-sequence checking
+- Multiple valid solutions where possible
+- Pressure comes from evolving systems, not arbitrary timers
+- Progression unlocks access, tools, and scope, not RPG stats
+- Deterministic systems so content is testable and agent-friendly
+- The dirty VM state is the game — preserve it, do not erase it
+

+```
+
+---
+
+## 4. RUNTIME MODEL
+
+### 4.1 Game Server — Node.js
+
+The game server (`server/src/index.js`) is a Node.js/Express application:
+- Serves `frontend/dist/` as static files at `/`
+- WebSocket server on the same port (real-time event push to HUD)
+- On startup: loads all content JSON, hydrates services from save file,
+  ensures workstation VM is live via VMManager
+
+The server is responsible for:
+- All game logic (quest state, trust, progression, incidents)
+- VM lifecycle management (virsh via child_process)
+- Validation — SSH into target VMs and evaluate rules
+- Save/load (single JSON file at `~/.local/share/sysadmin-chronicles/save.json`)
+- WebSocket broadcast of trust changes, new mail, shift ticks, incident alerts
+
+### 4.2 Frontend — Svelte
+
+The web HUD (`frontend/src/`) is a Svelte single-page app:
+- Built with Vite; output lands in `frontend/dist/` and is served by the game server
+- All data fetched from the game server API; no local state beyond UI
+- WebSocket client for real-time updates
+- Does not run validation — only displays results
+
+### 4.3 Target Platform
+
+- Host OS: Linux
+- Supported deployment model: start game server on host, view workstation via SPICE
+- Required host: KVM, libvirt, virsh, Node.js 18+, virt-viewer
+- Required install model: one-time host setup with clean uninstall path
+
+No Windows, macOS, or browser target is planned for the host. The HUD is a web
+app served locally — it is never exposed to the internet.
+
+---
+
+## 5. VIRTUAL MACHINE SYSTEM
+
+### 5.1 Required Stack
+
+- `qemu-system-*`
+- `KVM`
+- `libvirtd`
+- `virsh`
+- libvirt virtual networks
+- qcow2-backed VM images
+
+Runtime policy:
+- The shipped game should not require broad `sudo` usage during normal play
+- One-time host setup may require admin approval
+- Ongoing gameplay should run as a regular user against a prepared VM runtime
+
+### 5.2 Core Behavior
+
+The game controls VMs through libvirt, not by emulating them internally.
+
+Responsibilities:
+- Ensure required domains and networks exist
+- Start the active VM
+- Stop or suspend inactive VMs
+- Revert to known snapshots for resets
+- Query runtime state for evaluation
+- Attach the player to the appropriate VM workflow
+
+The workstation and at least one target VM must be able to run at the same
+time. This is required for real SSH-based play and for background incidents to
+continue evolving while the player works elsewhere.
+
+Operational guidance:
+- `workstation` stays live during normal play
+- At least one target VM stays live with it
+- Later phases may keep all major quest VMs active simultaneously
+- Resource budgets should be documented and enforced conservatively
+
+Lab finding:
+- Small headless target VMs were inexpensive on the test host
+- The workstation became materially heavier once a real graphical session and
+  browser were added
+- Budget the workstation separately from server-style quest VMs
+
+### 5.3 Initial VM Roles
+
+| ID | Role | Distro | Hostname | Purpose |
+|----|------|--------|----------|---------|
+| `workstation` | Player desktop | Debian 12 | `ares` | XFCE + Chromium HUD + Tilix terminal |
+| `web_server` | Service host | Debian 12 | `hermes` | Web/service quests (Q002–Q005, Q007) |
+| `build_machine` | Build box | Arch | `vulcan` | Package/build/update quests (Q006, Q008) |
+
+### 5.3.1 Workstation Profile
+
+The workstation is a full XFCE desktop (Debian 12, 768–1536 MB RAM):
+- **Chromium** — opens `http://192.168.100.1:3000` on login (game HUD)
+- **Tilix** — split-pane terminal, set as default; player SSHes to hermes/vulcan from here
+- **Full sysadmin CLI toolkit** pre-installed (vim, htop, tmux, curl, nmap, tcpdump, etc.)
+- SPICE display with QXL video — dynamic resolution via vdagent; fullscreen via `remote-viewer`
+- `always_live: true` — stays running between shifts; suspended on game quit, resumed on next launch
+
+Player never needs to interact with the workstation VM's internal file system for
+game objectives — all quest work happens on the target VMs via SSH.
+
+### 5.3.2 Why XFCE + Chromium (not terminal-only)
+
+Earlier iterations used a terminal-only workstation. The game was redesigned
+because a terminal-only approach would require building a fake terminal and fake SSH.
+The XFCE + real browser approach is simpler, more realistic, and requires no
+terminal simulation at all:
+
+- Player uses a real Tilix terminal — no simulation
+- Player SSHes with real SSH — no protocol emulation
+- The HUD is a real web app — no custom UI framework needed for game chrome
+- Downside: workstation VM costs ~480–768 MB RAM; budget accordingly
+
+### 5.4 Snapshot Strategy
+
+Snapshots are the reset primitive and the save primitive.
+
+Named snapshot tiers per VM:
+
+| Name | Purpose |
+|------|---------|
+| `baseline.clean` | Authored starting state for a fresh quest arc |
+| `baseline.recovery` | Fallback if live state is unrecoverable |
+| `checkpoint.shift-{N}` | Auto-saved at start of each in-game shift |
+
+Rules:
+- Snapshot names are deterministic
+- Quest scripts may declare required baseline snapshots
+- Validation never depends on snapshot history; only current observed state
+- The game retains a maximum of 5 shift checkpoints per VM; older ones are pruned
+- `baseline.clean` and `baseline.recovery` are never pruned by the game
+
+### 5.5 Networking Model
+
+Networking is host-controlled through libvirt.
+
+Supported modes:
+- `quest`: constrained, deterministic virtual networks and fixtures
+- `sandbox`: broader connectivity for experimentation
+
+Examples:
+- Internal-only network between workstation and target VM
+- Broken DNS as part of a quest
+- Deliberately degraded service reachability
+- Optional outbound package mirror access for selected scenarios
+
+### 5.6 VM Provisioning Hooks
+
+Quest-specific VM state — broken configs, missing files, log histories — is
+authored into the VM baseline before the snapshot is taken. This is done via
+idempotent provisioning scripts:
+
+```
+tools/vm/quest-prep/Q0XX-prep.sh
+```
+
+These scripts run against the target VM before the quest's `baseline.clean`
+snapshot is taken. They are never run at quest activation time. See
+QUEST_AUTHORING.md for the full provisioning workflow.
+
+---
+
+## 6. OBSERVATION AND VALIDATION
+
+### 6.1 Validation Philosophy
+
+Quest completion is based on **system state**, not on how the player got there.
+
+Allowed evidence includes:
+- Files and directory contents
+- Ownership and permissions
+- Service state
+- Process state
+- Open ports
+- Package state
+- Mount state
+- Disk utilization
+- System configuration values
+
+Disallowed as primary success conditions:
+- Specific commands typed
+- Specific files opened
+- UI click history
+
+### 6.2 Observation Sources
+
+Primary sources:
+- `virsh domstate`, `domifaddr`, and domain metadata
+- Host-driven inspection tooling such as libguestfs where practical
+- SSH-based read-only checks initiated by the host when needed
+- Quest-specific host probe scripts for higher-level state summaries
+
+Authoritative rule:
+- Quest validation must use host-authoritative checks only
+- In-guest helpers may improve responsiveness, but cannot decide success
+
+In-guest helpers should use neutral names (examples: `atlas-index`, `yardd`,
+`ops-telemetry-cache`) and must not be trusted as a security boundary.
+
+Operational note:
+- Routine package operations inside guests may emit maintenance or virtualization
+  notices that break immersion
+- Base images should suppress or tune guest maintenance messaging where safe
+  for the authored environment
+- Validation and incident design should not rely on noisy package-manager side
+  effects being visible to the player
+
+### 6.3 Validation Rule Model
+
+Core rule families:
+- `file_exists` / `file_contains` / `file_mode` / `file_owner`
+- `directory_exists`
+- `service_state` / `service_enabled`
+- `process_running` / `process_user`
+- `port_listening`
+- `package_installed`
+- `mount_present`
+- `disk_usage_below` / `disk_usage_above`
+- `command_assert` — fallback only, must verify state not behavior
+- `and` / `or` / `not`
+
+### 6.4 Trust Boundary
+
+The player may gain root access on some machines. The guest is not trusted. The
+host validation layer is trusted. Anti-cheat is achieved through external
+validation, not secrecy.
+
+---
+
+## 7. GAMEPLAY SYSTEMS
+
+### 7.1 Core Loop
+
+1. Ticket arrives with incomplete context
+2. Player evaluates urgency against other active problems
+3. Player enters or connects into the relevant VM
+4. Player investigates using real Linux tools
+5. Player applies a fix
+6. Game validates resulting state
+7. World reacts
+8. Trust shifts
+9. Future conditions reflect earlier choices
+
+### 7.2 System Pressure
+
+Pressure is systemic, not a countdown bar. Examples:
+- Disk usage keeps climbing
+- A log fills with worsening symptoms
+- A degraded service starts affecting another team
+- A quick fix suppresses one symptom while creating later instability
+
+Pressure is authored as state transitions and event chains via incident files.
+
+### 7.3 Trust / Reputation
+
+Trust measures how much the organization relies on the player.
+
+Trust affects:
+- sudo scope
+- accessible machines
+- diagnostic tooling
+- ticket sensitivity
+- documentation visibility
+
+**Trust increases** when the player resolves problems cleanly, finds root causes,
+and avoids collateral damage.
+
+**Trust decreases** when the player breaks unrelated systems, applies fragile
+fixes, ignores urgent incidents, or resolves symptoms but not causes.
+
+**Trust revocation**: if trust falls below a declared threshold in the trust
+unlock table, specific access strings are revoked. A subsequent trust increase
+does not automatically restore revoked access — the player must re-earn the
+unlock tier. Revocation rules must be explicitly declared per unlock tier.
+
+### 7.4 Multiple Valid Solutions
+
+Quests support realistic alternatives where possible:
+- quick workaround
+- operationally acceptable fix
+- proper long-term fix
+
+Branch resolution rule:
+- multiple branches may match the same final state
+- each branch must declare a numeric `priority`
+- the highest matching priority wins
+- ties are a content error and fail validation during authoring checks
+
+### 7.5 Dynamic Events
+
+Dynamic events inject prioritization pressure and are authored in incident files.
+Events are selected from authored pools and activated by progression, trust,
+current system state, and world flags.
+
+Each incident declares a `blast_radius_quests` list so the incident scheduler
+can avoid activating an incident that would corrupt active quest evidence or
+simultaneously interfere with an in-progress objective.
+
+### 7.6 Investigation Quality
+
+Clues must be legible and grounded. Every quest declares a `clue_fingerprint`
+documenting what evidence exists in the VM baseline. Content validation checks
+that the fingerprint is plausible. The player should feel rewarded for competent
+debugging rather than guessing.
+
+### 7.7 Progression
+
+Progression unlocks:
+- broader sudo access
+- new servers
+- more dangerous responsibilities
+- better internal docs
+- helper scripts and diagnostics
+
+This is institutional progression, not character stats.
+
+### 7.8 Mentor Thread
+
+Marcus is the primary mentor character. His dialogue runs across the full game
+as a `series_id: marcus-main` thread. Each dialogue file that belongs to an
+ongoing character relationship declares `series_id` and `series_position`.
+
+The dialogue system tracks series state so Marcus remembers what happened in
+earlier quests and can reference it in later ones. This is the primary vehicle
+for institutional memory and character continuity.
+
+### 7.9 Tone and Humor
+
+The tone is dry, realistic, and slightly dysfunctional. Examples:
+- contradictory runbooks
+- tickets that misidentify the problem
+- passive-aggressive internal notes
+- perfect urgency attached to trivial formatting requests
+
+Humor must support immersion, not break it.
+
+---
+
+## 8. COMMAND AND ACCESS MODEL
+
+Access is controlled realistically through:
+- user accounts and group membership
+- sudoers configuration
+- reachable hosts
+- available packages and tooling
+
+If a player cannot run `systemctl`, the reason is that the VM account lacks the
+required privileges, not that the game disabled the verb.
+
+---
+
+## 9. PRESENTATION LAYER
+
+The player's view is the workstation VM desktop, viewed fullscreen via SPICE:
+
+```bash
+scripts/start-game.sh
+# → starts game server
+# → virsh start sc-workstation (if not already running)
+# → remote-viewer --full-screen spice://127.0.0.1:<port>
+```
+
+The player sees an XFCE desktop with Chromium pre-opened to the HUD.
+
+### 9.1 VM Display
+
+- **Protocol**: SPICE with QXL video driver
+- **Client**: `remote-viewer` (from `virt-viewer` package) in fullscreen mode
+- **Resolution**: dynamic — guest vdagent resizes to match host display
+- **Cursor release**: `Ctrl+Alt`; fullscreen toggle: `F11`
+- **Clipboard sharing**: via spice-vdagent in the guest
+
+No VNC, no custom viewer widget. The host runs `remote-viewer` and the player
+works inside the workstation VM.
+
+### 9.2 HUD (Svelte Web App)
+
+The game HUD is a Svelte single-page app served at `http://192.168.100.1:3000`:
+
+- **TicketsPanel** — ticket list, detail view, "Mark Complete" button
+- **MailPanel** — inbox, message body, reply buttons (where applicable)
+- **DocsPanel** — trust-gated internal docs, rendered from content/docs/
+- **SagePanel** — chat interface to SageService knowledge base
+- **HeaderBar** — trust indicator (no number, behavior only), shift timer, unread badge
+
+The HUD is a company intranet portal in look and feel — dark, monospace, minimal.
+
+### 9.3 One-Time Setup and Uninstall
+
+Host-side setup is unavoidable (KVM, libvirt, VM images). It must be simple.
+
+Principles:
+- one-time setup only (`tools/setup/first-run-setup.sh`)
+- plain-language explanation of what will be installed
+- managed resources use the `sc-` prefix (never touch other libvirt domains)
+- full uninstall removes all game-owned domains, networks, storage, helper files
+- normal gameplay does not require broad `sudo`
+
+---
+
+## 10. DATA MODEL
+
+Authoring formats:
+- JSON for quests, tickets, incidents, dialogue, documentation metadata
+- Shell helper scripts where CLI integration is necessary
+
+Top-level content domains:
+
+| Domain | Purpose |
+|--------|---------|
+| `quests/` | Objective chains and validation rules |
+| `tickets/` | Player-facing problem statements |
+| `incidents/` | Dynamic system pressure events |
+| `dialogue/` | Workplace messages, hints, follow-ups |
+| `docs/` | Internal documentation metadata/content |
+| `progression/` | Trust thresholds, unlocks, access tiers |
+| `vm_profiles/` | Domain names, snapshots, networks, probe config |
+| `helpers/` | Non-obvious guest helper naming/config data |
+| `world_flags/` | Central registry of all world state flags |
+
+Each authored scenario must declare:
+- `required_vms` — all VMs the quest touches
+- `baseline_snapshot` — starting snapshot for this quest
+- `clue_fingerprint` — evidence declared in the VM baseline
+- validation rules and branch priorities
+- escalation behavior
+- trust impact
+- `blast_radius` — incident IDs the quest may interact with
+- follow-on world effects
+
+---
+
+## 11. SAVE MODEL
+
+### 11.1 Dirty State Model
+
+The game uses a **dirty state model**. VM disk state is preserved across
+sessions as-is. The game does not revert to a clean baseline on load — it
+resumes from whatever state the VMs are currently in.
+
+This is intentional. The player's history of changes is part of the game. A
+machine they fixed stays fixed. A machine they damaged stays damaged until they
+repair it or request reimage.
+
+Two persistence layers:
+
+**Game State Layer** — saved as JSON:
+- Trust score and history
+- Unlocked access, sudo scopes, docs, tools
+- Active/completed quest and ticket state
+- World flags (current values and change history)
+- Incident scheduler state
+- In-world clock and shift counter
+
+**VM State Layer** — saved as libvirt snapshot references:
+- Per-VM reference to current snapshot tier or live disk
+- Per-VM managed recovery checkpoint list
+- Reimage history per VM
+
+### 11.2 Shift Checkpoints
+
+At the start of each in-game shift:
+1. Game state JSON is saved
+2. A named snapshot is created per active VM: `checkpoint.shift-{N}`
+3. The checkpoint reference is recorded in the save file
+4. Shift checkpoints beyond the retention limit (default: 5) are pruned
+
+Shift checkpoint rollback is an explicit player action ("start this shift
+over") with a confirmation prompt. It does not undo trust changes or dialogue
+already delivered.
+
+### 11.3 Load-Time Reconciliation
+
+On load, the observation service validates current VM state against saved world
+flags. Minor drift is handled silently. Major drift — missing snapshots,
+unbootable VMs — triggers the recovery flow.
+
+If a referenced snapshot is missing:
+- If `baseline.recovery` exists, offer resume from recovery
+- If `baseline.recovery` is also gone, the VM is treated as unrecoverable
+
+### 11.4 Recovery / Reimage Flow
+
+When a VM is unrecoverable, the player can report it for reimage through an
+in-world mechanic:
+
+1. Player submits a reimage request (ticket to management)
+2. In-world delay is imposed (one in-game shift)
+3. Machine is restored from `baseline.recovery` or `baseline.clean`
+4. Trust penalty is applied based on severity
+5. In-progress quests on that VM are reset
+6. Evidence from before the reimage is gone — acknowledged in-world
+
+This is the designed escape valve. It has visible consequences but allows
+forward progress.
+
+### 11.5 Host Storage Management
+
+qcow2 images with many snapshots can balloon. The game enforces:
+- Maximum of 5 shift checkpoints per VM (configurable in vm_profile)
+- Authored baseline and recovery snapshots are never pruned by the game
+- `resource_budget` in vm_profile declares expected disk footprint
+
+### 11.6 Developer Reset
+
+Not available in the shipped game. CLI only:
+
+```bash
+bash tools/vm/snapshot-all.sh --revert-to baseline.clean
+```
+
+Completely resets all VMs to authored baseline. Used during content authoring
+and automated test runs.
+
+---
+
+## 12. MODULE BREAKDOWN
+
+### Server (`server/src/`)
+
+| Module | Responsibility |
+|--------|----------------|
+| `index.js` | Express + WebSocket entry point; service wiring; static file serving |
+| `ContentLoader` | Loads all content/ JSON at startup; never writes |
+| `QuestEngine` | Quest state machine (pending → active → resolved) |
+| `TicketService` | Ticket state, mark-complete handler, branch resolution |
+| `ValidationEngine` | SSH into VMs, evaluates all rule types against real state |
+| `VMManager` | virsh start/stop/snapshot/getIP wrappers |
+| `TrustSystem` | Score tracking, unlock evaluation, revocation |
+| `ProgressionSystem` | Unlocked docs, VMs, access strings |
+| `EmailService` | Inbox, follow-up emails, reply options, WebSocket push |
+| `SageService` | Rule-based dialogue / knowledge base |
+| `ShiftTimer` | Shift clock, broadcasts shift:tick via WebSocket |
+| `IncidentScheduler` | Pressure tick loop, incident injection |
+| `ShiftReviewService` | End-of-shift performance review email generation |
+| `CertificationService` | Awards internal certs after quest chain completion |
+| `SaveState` | Read/write `~/.local/share/sysadmin-chronicles/save.json` |
+| `lib/ssh.js` | Promisified SSH command execution (node-ssh) |
+| `lib/virsh.js` | virsh command wrappers |
+| `lib/eventBus.js` | Internal Node.js EventEmitter for service coordination |
+
+### Frontend (`frontend/src/`)
+
+| Component | Responsibility |
+|-----------|----------------|
+| `App.svelte` | Root component; WebSocket connection; panel routing |
+| `TicketsPanel` | Ticket list, detail, mark-complete flow |
+| `MailPanel` | Inbox, message body, reply buttons |
+| `DocsPanel` | Trust-gated doc list and content viewer |
+| `SagePanel` | Chat interface, follow-up prompts |
+| `VmsPanel` | Live VM status indicators |
+| `HeaderBar` | Trust display, shift timer, mail unread count |
+| `lib/api.js` | Fetch wrapper for all REST API calls |
+
+---
+
+## 13. SECURITY AND SAFETY
+
+Requirements:
+- Scope libvirt resources to dedicated game domains/networks/storage pools
+- Never operate on arbitrary host VMs by default
+- Use explicit naming/prefixing for all game-managed resources (`sc-` prefix)
+- Separate quest-mode constrained networks from broader sandbox networks
+- Prefer least-privilege host integration
+- Provide a dry-run and diagnostic mode for development scripts
+
+The game manages only the resources it created or was explicitly pointed at
+during setup.
+
+---
+
+## 14. TECHNOLOGY DECISIONS
+
+| Technology | Role | Reason |
+|-----------|------|--------|
+| Node.js / Express | Game server | Async I/O, native SSH/virsh via child_process, easy JSON |
+| Svelte / Vite | Web HUD | Lightweight, no virtual DOM overhead, fast build |
+| WebSocket (`ws`) | Real-time push | Trust changes, mail, incidents without polling |
+| QEMU/KVM | Virtualization backend | Real Linux environments |
+| libvirt / virsh | VM lifecycle control | Standard Linux automation surface |
+| SPICE + QXL | Workstation display | Dynamic resolution, clipboard sharing, fullscreen |
+| `remote-viewer` | Host-side SPICE client | Ships with virt-viewer; fullscreen with F11 |
+| JSON | Content authoring | Data-driven, easy to diff, unchanged from prior design |
+| node-ssh | SSH execution in validation | Clean Promise API; BatchMode, key-based auth |
+
+Not in scope: v86, WebAssembly, browser-only runtime, service-worker networking.
+
+---
+
+## 15. DEVELOPMENT PRIORITIES
+
+1. Native architecture consistency
+2. VM control integration
+3. Observation and validation
+4. Core gameplay loop
+5. Pressure, trust, and dynamic event systems
+6. Presentation polish
+
+If a design choice improves presentation but weakens VM realism or maintainable
+automation, reject it.
