1. Evidence Base (Decompilation Corpus)

Artifact	Source	Decompile/Extract	Size
ZuneShell_Dll (managed)	Zune-x86.msi	ilspycmd → tools/disassembly/zuneshell/	821 C# files (ZuneUI/ = 685)
ZuneDBApi_Dll (managed)	Zune-x86.msi	ilspycmd → tools/disassembly/zunedbapi/	1,030 C# files (19 namespaces)
ZuneShellResources_Dll RCDATA	Zune-x86.msi	7z PE extraction → tools/disassembly/zuneshell_resources/	1,857 resources (241 .UIX documents, 1,289 PNG, 44 JPG, 4 WAV)
zune-x64.msi	ZuneSetupPkg.exe	inventoried → tools/disassembly/setup_pkg/x64/	x64 player payload (same managed code as x86)
zunewmdu-x86/x64.msi	ZuneSetupPkg.exe	7z → tools/disassembly/wmdu/	ZuneWmduDLL (native firmware-update service)
Native component stack	Zune-x86.msi	inventoried → tools/disassembly/msi/	UIX engine ×5, ZMDB engine ×4, codecs, MTPZ, bus driver, services

Both review/ZunePackage.exe and review/ZuneSetupPkg.exe verified: ZunePackage.exe sha256 ef5e5deb… identical to the previously disassembled copy (no rework required). ZuneSetupPkg.exe is the offline multi-language setup bootstrapper containing the x86/x64 MSI set.

Zune 4.8 native component map (from MSI payload)

• Iris UIX engine: UIX_Dll, UIXcontrols_Dll, UIXrender_Dll, UIX_renderapi_Dll, UIXsup_Dll (native Direct3D declarative renderer)
• Database (ZMDB): ZuneDB_dll, ZuneDBApi_Dll (managed API), engine variants ZuneZMDBClassicDLL, ZuneZMDBLibraryDLL, ZuneZMDBMobileDLL, ZuneZMDBZuneHDDLL
• Audio: ZuneSE_dll, ZuneAACDec_Dll, ZuneSrcWrpDLL, ZuneEncEngDLL + ZuneEncEXE (MP3/WMA/AAC encoders), l3codecp.acm
• Video: ZuneH264Dec_Dll, ZUNEMp4Dec_Dll, ZuneDXVA2_Dll, ZuneEvr_Dll
• Device/USB: ZuneMTPZ_dll (MTPZ), Zumbus.sys + INF (kernel bus driver), ZuneBusEnumSvc, ZuneDriver_dll, ZuneUsbTransport_dll, ZuneIpTransport_dll, ZuneTcp2Udp_dll, WMZUNE* (USB-PPP)
• Services: ZuneService_Dll, ZuneNssExe/ZuneShareEXE (network sharing), ZuneWlanCfgSvc, ZuneNetProxy_dll, ZuneCfg_Dll, ZuneConfigEXE
• Shell integration: ZuneShellExt_Dll, ZuneTaskbar_Dll, ZuneLauncherEXE
• Marketplace/DRM: ZuneMarketplaceResources_Dll, PPCRL/MSIDCRL (Passport auth), ContentDirectoryXML, MediaReceiverRegistrarXML (UPnP/WMC)

2. Executive Summary

Not-Zune is a faithful UI shell with a growing feature set built on clean architecture, but it has one critical structural gap: there is no real audio playback engine — AudioEngine (src/NotZune.Infrastructure.Audio/AudioEngine.cs) is a position-ticker simulation and no audio library (NAudio/ManagedBass) is referenced anywhere. Every audible experience (music, crossfade, ReplayGain, volume, the visualizer, podcast streams) is currently simulated; the only real audio output is SoundEffectService playing authentic Zune WAV chimes through OS CLI players.

Domain	Parity	Verdict
A. Shell & Navigation	HIGH (~85%)	Authentic chrome, pivots, transport, shortcuts
B. Quickplay	MEDIUM (~65%)	Decks + Smart DJ substitute; no hub artwork maps
C. Collection (music)	HIGH (~80%)	Full browsing/editing; Find-Album-Info is art-only
D. Now Playing	HIGH (~75%)	Ken-Burns + real metadata; no video clips
E. Mixview	MEDIUM (~60%)	Constellation + MixStack; similarity is local-only
F. Audio engine	SIMULATED (0%)	No sound; all DSP is fake
G. CD Land	SIMULATED (~40%)	Full UI, simulated rip/burn (no drive available)
H. Device sync & lifecycle	SIMULATED (~35%)	Gas gauge UI real; sync/firmware simulated
I. Podcasts	PARTIAL (~50%)	RSS subscribe; no marketplace; playback simulated
J. Social / Marketplace / Account	N-A (substitute ~70%)	Zune Card local substitute; servers dead
K. Settings & Management	HIGH (~75%)	Two-tier pivots + persistence (Phase 4)
L. First-launch & onboarding	MISSING (0%)	No wizard
M. Platform services (ZMDB, sharing)	PARTIAL (~40%)	SQLite substitute; no UPnP/share/MUI

Weighted overall parity: ≈ 55–60% (weighting UI presentation strongly, hardware-dependent features neutrally).

Top 3 actions for Phase 5:

1. Real audio playback engine — integrate a cross-platform .NET 8 audio library (NAudio WASAPI/ALSA or ManagedBass); this unblocks crossfade, ReplayGain, volume, gapless, FFT visualizer, and podcast playback. Everything else in the audio domain is blocked on this.
2. First-launch onboarding wizard (welcome → monitored folders → privacy → done; mirrors FirstLaunchLand flow).
3. Find Album Info track matching — extend the Phase 4 art lookup to the per-track metadata review dialog Zune used (FINDALBUMINFOSONGMATCH.UIX).

---

5. Phase 5+ Roadmap (ranked)

1. P0 — Real audio playback engine. Add NAudio (WASAPI on Windows, ALSA/PulseAudio on Linux) or ManagedBass to Infrastructure.Audio; rewire PlaybackQueueCoordinator to a real output device. Unblocks: volume, crossfade, gapless, ReplayGain, FFT visualizer, podcast/CD playback. This is the single highest-leverage parity item.
2. P1 — First-launch wizard (FIRSTLAUNCH.UIX flow): welcome → monitored folders → done, with demo-data decision point.
3. P1 — Find Album Info track matching: per-track MBID resolution + review dialog (FINDALBUMINFOSONGMATCH.UIX parity), optionally honoring WriteTagsToFile.
4. P2 — Smart/auto playlists (AUTOPLAYLISTDIALOG.UIX parity): rule-builder persisted like ZPL playlists.
5. P2 — Mixview rating tiles wiring (like/hate/info/add actions on constellation nodes using the already-extracted MIX.* assets).
6. P3 — Video support (playback engine extension + VIDEOLIBRARY.UIX view) and Photo library + slideshow.
7. P3 — Sync UX polish (sync animation, instruction toast, notification area).
8. Deferred (N-A/hardware): MTPZ device sync internals, firmware update/restore, wireless pairing, UPnP sharing.

6. Audit Confidence Notes

• Managed-code evidence is complete (ZuneShell_Dll + ZuneDBApi_Dll fully decompiled); native components (UIX_*, ZuneSE_dll, ZuneEncEngDLL, ZuneMTPZ_dll, Zumbus.sys) were inventoried but not disassembled at machine-code level — their behavior is inferred from names, interfaces, strings, and the managed layers that call them.
• UIX documents are compiled .uib bytecode in ZuneShellResources_Dll RCDATA; the 241 .UIX source names + 1,289 asset names used here come from the resource table (assets previously ingested into src/NotZune.UI/Assets/Zune/).
• Feature statuses were verified against the Not-Zune source tree (13 views, 13 view-models, 10 application interfaces, 6 application services, 4 infrastructure projects, 58 passing tests) as of commit 6570600.
