Summary

  • AI-Enhanced Dialogue toggle (#646, D-138): settings panel toggle with layered hardware detection (RAM/TPT/degradation), battery auto-suspend with player override and warning label. Protocol v19→v20 bump with ChangeSettings/RequestAllSettings IPC.
  • PlatformInfo autoload (#659, D-141): client-side OS abstraction centralizing all platform queries — power state (with PowerProfile enum), memory, CPU, GPU, display, locale, file paths, and get_diagnostics() helper for bug reports. 23 properties, 1 signal, 2 methods.
  • HardwareDetector refactored to consume PlatformInfo instead of calling OS directly. AiDialogueDetector (duplicate) deleted.
  • 67 tests covering toggle behavior, hardware detection thresholds, battery suspend/resume, PlatformInfo interface.
  • D-141 filed (PlatformInfo architecture), Q-059 resolved (full interface scope).

Test plan

  • Verify settings panel shows "AI-Enhanced Dialogue" toggle with status dot
  • Toggle sends ChangeSettings IPC to server, server persists in SQLite
  • Hardware detection: RAM < 1.6GB → toggle greyed out; 1.6-2.0GB → marginal warning; ≥2.0GB → pass
  • Battery suspend: unplug → auto-suspend + warning label; toggle stays clickable (player override)
  • Plug back in → auto-resume if player pref was ON
  • PlatformInfo.get_diagnostics() returns all 23 properties + 7 paths
  • 67 GDScript tests pass

Implements the full AI-Enhanced Dialogue feature for Sprint 26:

- HardwareDetector autoload (extends Node): three-layer detection —
  Layer 1 RAM classification (pass/marginal/fail, thresholds 2GB/1.6GB),
  Layer 2 TPT benchmark cache (green/yellow/red, thresholds 6/3 t/s),
  Layer 3 degradation monitoring (>40% drop → yellow). load_ai_pref()
  restores toggle state from user://settings.cfg on startup.

- Settings dialog AI section: toggle, colored status dot, status message
  label, testable API (get_ai_dialogue_label_text, set_ai_dialogue_
  hardware_status, is_ai_dialogue_toggle_enabled). Only RAM "fail" greys
  out toggle — player always overrides yellow/red recommendations (D-138).

- GameState.ai_enhanced_dialogue_enabled (default true, opt-out model).
  GameState.settings_response (v20 one-shot settings dump from server).
  apply_snapshot() hydrates ai_enhanced_dialogue_enabled from full dump.

- Protocol v19→v20, settings_response decoding in decode_snapshot().
  Protocol converted to extends Node autoload (enables test has_method).
  encode_change_settings() helper for test inspection.

- InputMapper: CHANGE_SETTINGS, REQUEST_ALL_SETTINGS, DELETE_SETTING.
  SimBridge: wire mappings for all three. RequestAllSettings queued after
  handshake to hydrate client state from server SQLite on connect.
  settings_response carry-forward in receive_bytes().

Platform abstraction:
- New PlatformInfo autoload (extends Node, registered first in project.godot).
  Owns all OS queries: power state monitoring (30s poll), memory (on demand),
  file path resolution (user_data_dir, config_dir, benchmark_cache_path,
  install_dir, executable_path, cache_dir, model_dir).
- PowerProfile enum (FULL/BATTERY/POWER_SAVER), power_profile_changed signal.
  Uses OS.callv("get_power_info") to defer resolution to runtime — avoids
  compile errors on Godot 4.6 headless builds without power API.

HardwareDetector refactor:
- check_ram() now delegates to PlatformInfo.refresh_memory() + free_memory_mb.
  All direct OS.get_memory_info() calls removed.
- classify_power_state(int) and should_suspend_inference(int) delegate to
  PlatformInfo for single source of truth.
- check_power_state() → {power_state, classification, should_suspend}.
- Battery suspend/resume: on PowerProfile.BATTERY, stores pre-battery pref and
  sends ChangeSettings(false) to server. On FULL restore, sends ChangeSettings
  with saved pref if it was enabled. inference_suspended member tracks state.

Settings dialog:
- is_ai_inference_suspended() / set_ai_inference_suspended(bool) — testable API
  per Hoshe's test contract. Reads HardwareDetector.inference_suspended on open.
- Toggle now disabled when battery-suspended OR hardware fails (not only fail).
- get_ai_dialogue_label_text() wired to UIStrings ("settings.ai_dialogue_toggle")
  instead of hardcoded string.

Cleanup:
- Deleted ai_dialogue_detector.gd and .uid (orphaned duplicate, dead code).

23 properties, 2 methods, 1 signal:
- Power: raw_power_state + battery_percent added to _poll_power()
- CPU: cpu_name (OS.get_processor_name), cpu_logical_cores
- GPU: gpu_name, gpu_vendor, gpu_api_version, gpu_type (mapped from
  RenderingDevice.DeviceType), gpu_driver_info — all guarded for headless
- Platform: platform_name, os_version, distribution, is_sandboxed
- Display: screen_count, screen_size, screen_dpi, screen_refresh_rate,
  display_scale (macOS screen_get_scale / dpi÷96 fallback)
- Locale: locale, locale_language
- get_diagnostics() -> Dictionary for bug report inclusion
- OS.get_distribution_name() and DisplayServer.screen_get_scale()
  use callv() pattern for headless build safety

Player autonomy wins: AI Dialogue toggle is only greyed out for RAM fail
(< 1.6 GB free). Battery suspend shows a warning label instead of
disabling the toggle — player can override the auto-suspend at any time.

Changes:
- settings_dialog: toggle disabled = hw_status == "fail" only
- settings_dialog: add _ai_battery_warning_label (STATUS_YELLOW) shown
  when _ai_inference_suspended; hidden when plugged back in via
  set_ai_inference_suspended()
- settings_dialog: is_ai_dialogue_toggle_enabled() no longer checks
  _ai_inference_suspended
- settings_dialog: set_ai_inference_suspended() updates warning label
  visibility, not toggle disabled state
- ui-strings: add settings.ai_battery_warning "High battery usage"

config_dir, benchmark_cache_path, executable_path, model_dir were
populated in _init_paths() but missing from the diagnostics dict.

Review: client -> main (type: code) — PR #90

Hoshe (Code Quality): REQUEST_CHANGES

Well-structured feature with extensive tests. PlatformInfo and HardwareDetector are cleanly separated. Four issues need addressing before merge.

# File Severity Issue
1 settings_dialog.gd:247 warning Toggle fires SimBridge.send_input() with no connection state guard — will bounce back on reconnect if toggled before server connects
2 project.godot:autoloads warning HardwareDetector autoload ordering is correct but fragile — no assert or comment enforcing PlatformInfo-first dependency
3 hardware_detector.gd:78 warning read_benchmark_cache() opens FileAccess but doesn't close explicitly — use FileAccess.get_file_as_string() instead
4 game_state.gd:353 warning Settings hydration silently drops non-Dict val — no fallback for plain bool or push_warning on mismatch
5 hardware_detector.gd:29 suggestion _pre_battery_pref initialized to true but not synced from GameState after load_ai_pref() — narrow race on startup-on-battery
6 settings_dialog.gd:203 suggestion "red" status caught by "marginal", "yellow", "red" arm → gets yellow dot, not red — likely logic error
7 test_ai_dialogue_sprint26.gd:688 suggestion Battery-sensitive test asserts unconditionally — will false-fail if CI runs on battery hardware

Tyre (Architecture): APPROVE

Clean architectural work. PlatformInfo correctly centralizes OS queries behind a single seam. The layered separation (PlatformInfo → HardwareDetector → SettingsDialog) follows existing autoload patterns and respects D-010 information boundaries. Wire protocol additions are consistent with existing encode/decode patterns. D-141 properly filed.

# File Severity Issue
1 project.godot:autoloads suggestion Dependency ordering comment would help future maintainers
2 settings_dialog.gd:247 suggestion Toggle sends IPC without connection guard (agrees with Hoshe)
3 game_state.gd:344 suggestion Tagged-union val["Bool"] extraction is fragile if serde encoding changes
4 settings_dialog.gd:338 suggestion DebugConsole.PREFS_PATH creates compile-time dependency on DebugConsole

Verdict: CHANGES REQUESTED

Hoshe's 4 warnings need to be addressed. The connection guard on the settings toggle (#1) and the status dot color logic (#6) are the most impactful.

W1/A2: add SimBridge.CONNECTED guard before send_input in toggle handler
W2/A1: assert PlatformInfo != null in HardwareDetector._ready();
       add ordering comment in project.godot [autoload] section
W3: replace FileAccess.open() with get_file_as_string() in
    read_benchmark_cache() — auto-closes, no leak
W4/A3: add _extract_bool_setting() helper in game_state.gd that handles
       both {"Bool": true} and plain bool; push_warning on type mismatch
S5: sync _pre_battery_pref from GameState after load_ai_pref() in
    HardwareDetector._ready() — closes race if system starts on battery
S6: separate "red" TPT status into its own arm with STATUS_RED dot and
    label colour — three-colour mapping: green/yellow/red now distinct
A4: replace DebugConsole.PREFS_PATH compile-time dependency in
    _save_ai_pref() with local SETTINGS_CFG_PATH constant

S7 (battery CI guard) already applied by Hoshe in test file.

Re-review: client -> main (type: code) — PR #90

Hoshe (Code Quality): APPROVE

All 7 previous issues fixed. One new suggestion (non-blocking).

Previous Status
W1 connection guard FIXED
W2 autoload ordering FIXED (comment + runtime assert)
W3 FileAccess close FIXED (get_file_as_string)
W4 settings hydration FIXED (_extract_bool_setting helper)
S5 _pre_battery_pref FIXED
S6 red status dot FIXED
S7 battery test CI FIXED

New suggestion: Battery warning label tests don't call dialog.open() so _build_ui() never runs — tests pass/fail for the wrong reason. Production path is correct.

Tyre (Architecture): APPROVE

All 4 previous suggestions addressed. No new issues. Architecture is clean — PlatformInfo as OS abstraction, HardwareDetector as classification/policy, SettingsDialog as presentation.

Verdict: APPROVED — merged into main.
