# DeepPluck V0.10.2 Compact GUI Refinement — Implementation Report

Date: 2026-09-01

Branch: `master`

Starting HEAD: `2573cee23833e09a7d9e86c4e1de044138199809`

Implementation commit: `17ec6f0fc4ece47dce10e6fe9bbc70a000a59ca0` — `DeepPluck V0.10.2 Compact GUI Refinement`

## 1. Outcome

The complete automatable V0.10.2 Definition of Done passed. The fixed editor is now 1536 x 900, the Filter and FX sections use the requested focused layouts, buttons have a restrained modern relief, waveform and ADSR paths have the approved intermediate Amber glow, and the meter uses the requested Teal-to-soft-Cyan-to-Amber progression on its unchanged -60 to +6 dB scale.

No DSP, processor, parameter, preset, state, automation, plugin identity, Factory sound, voice, effects, or bus behavior changed. Manual Cubase, listening, Windows scaling, and audio-device acceptance remains open in section 11.

## 2. Normative inputs and scope protection

`AGENTS.md` and the complete `Docs/Sound/DeepPluck_Sound_Manifest_v1.0.md` were read before implementation. The V0.10.1 foundation and tracked V0.10 target mockup remained the architectural and visual base. The restrained relief and glow were kept subordinate to the Sound Manifest's calm, focused, low-clutter interface direction.

No file under `JUCE/` changed. No DSP, processor, parameter, preset, randomization, or effects source file changed. All sixty-two parameter IDs/order/version hints/ranges/defaults, four Factory sounds, plugin IDs, exactly sixteen musical voices, and the no-input/stereo-output instrument contract are unchanged.

## 3. Implemented GUI changes

- The fixed editor height is reduced from 1024 to 900 pixels. Header control sizing remains intact; the oscillator row, navigation, gaps, footer, and page area are compacted without removing a function.
- Filter On and the sole 112 x 112 Cutoff rotary occupy the left side of the Filter module. Resonance/Drive and Key Track/Env Amount form an exact two-by-two grid on the right.
- Every other rotary keeps the common 64 x 64 body size.
- Chorus, Delay, and Reverb keep fixed aligned Bypass and narrow Position columns.
- The three Mix controls share one exact vertical axis. Rate/Free Time/Size, Depth/Feedback/Pre-Delay, and Width/Tone/Damping form three further exact axes.
- Delay Free/Sync and Division are stacked vertically in a narrow auxiliary column between Free Time and Feedback.
- Text and icon buttons use a restrained surface gradient, one-pixel highlight, subtle lower edge shade, fine teal-grey outline, and dim Amber accent. Toggle switches retain their established switch treatment.
- Waveform and ADSR paths use a crisp 1.8-pixel Amber core plus three bounded glow strokes whose outer falloff extends approximately five pixels.
- The output meter keeps the exact -60 to +6 dB normalization: -60 dB is empty, 0 dB is `60/66` of the bar height, and +6 dB is full height. Its lit progression is Teal at the bottom, soft Cyan in the middle, and Amber at the top; no broad green/yellow/red traffic-light bands were added.
- Every accepted V0.10.1 correction remains active: preset-row indentation, full-height meter component, recognizable lock vector, Master Random/Amount Hover Help, aligned ordinary switches and labels, and vertical minimum-time ADSR slopes.

## 4. Automated GUI coverage and visual review

The `gui` suite now additionally verifies:

- exact fixed 1536 x 900 construction;
- one 112-pixel Cutoff rotary and 64-pixel bodies for every other rotary;
- Filter On/Cutoff ordering and the right-hand two-by-two grid;
- narrow vertically aligned FX Position fields;
- exact common columns for Mix, Rate/Free Time/Size, Depth/Feedback/Pre-Delay, and Width/Tone/Damping;
- non-overlapping stacked Delay Free/Sync and Division controls;
- the unchanged -60/0/+6 dB meter normalization;
- all earlier binding, attachment, layout, state-neutrality, preference, metering, Random/Lock, preset, envelope-geometry, and page-switching contracts.

Fresh build-local PNG snapshots of MAIN, MODULATION, FX, and SETTINGS were generated in both configurations. The final Release snapshots were visually reviewed at 1536 x 900. All controls remain contained and non-overlapping, the V0.10.2 labels are present, Filter and FX match the declared grids, and the intermediate Amber glow and button relief remain readable without overpowering the interface.

## 5. Confirmed environment and final commands

- Windows 11 x64
- Visual Studio 2026 Community 18.9.2
- generator `Visual Studio 18 2026`, architecture `x64`
- MSVC 19.51.36256.0 (`14.51.36231` tool directory)
- Windows SDK 10.0.26100.0
- CMake 4.4.3
- JUCE 9.0.1
- C++20

The final matrix used:

```powershell
cmake --fresh -S . -B build -G "Visual Studio 18 2026" -A x64
cmake --build build --config Debug --parallel
ctest --test-dir build -C Debug --output-on-failure
cmake --build build --config Release --parallel
ctest --test-dir build -C Release --output-on-failure
```

The fresh configure selected MSVC 19.51.36256.0 and Windows SDK 10.0.26100.0. The generated-input precheck resolved Debug and Release to 0.10.2.

## 6. Final build and test results

| Configuration | Build | Compiler errors | New compiler warnings | CTest result |
|---|---|---:|---:|---:|
| Debug | pass | 0 | 0 | 28/28 pass, 63.31 s |
| Release | pass | 0 | 0 | 28/28 pass, 17.18 s |

Both `artifact_version` tests passed. All existing DSP, headroom, performance, migration, preset, randomization, effects, integration, and audio-neutrality thresholds remain unchanged.

## 7. Version and local artifacts

`project(DeepPluck VERSION 0.10.2)` is the single authoritative current version. VST3 metadata, Standalone FileVersion/ProductVersion, generated JUCE macros, GUI labels, and project-local copies all resolve to 0.10.2.

| Project-local artifact | Bytes | SHA-256 |
|---|---:|---|
| Debug VST3 inner binary | 28,410,880 | `460439A714D3997D5427E914FCBE860CD66A769EB0F935B441A4FFEB97F4DFF8` |
| Debug Standalone | 28,853,248 | `AE07AE42EBF85AEFA0D819B066EA141DBD26171C70130415FAB1CDD22733BFFB` |
| Release VST3 inner binary | 9,422,336 | `798244EAF378CBF2189A1A9B7C668B258367AD8ABA4009C81B0F03EFF6BFF0D6` |
| Release Standalone | 9,441,792 | `0B0BADD1CC7DC9F8B0BA6C9328C9E803E7CFFD5B533859B30EC8020D10571A5C` |

Each build output is byte-identical to its `Artifacts/<configuration>` copy. Both complete VST3 bundles and both Standalone applications exist.

## 8. Standalone smoke

Both local Standalone applications reached input-idle with a nonzero native main-window handle, accepted a normal main-window close, exited within the timeout with code 0, and left no test process behind:

| Configuration | Window handle | Exit code |
|---|---:|---:|
| Debug | 3,081,980 | 0 |
| Release | 853,892 | 0 |

This verifies construction and clean shutdown. It is not a listening or audio-device acceptance claim.

## 9. Installation and repository hygiene

`COPY_PLUGIN_AFTER_BUILD` remains `FALSE`. The build copied only into project-local `Artifacts`. The pre-existing manually installed system VST3 was not modified: its inner binary and `moduleinfo.json` retain their 2026-08-31 16:30:58 timestamps and the recorded hashes `288F1BC88BBB8FCD131DA089846C3ED99D5E554B77EA9DA4A97EA18E2000FDC3` and `E42CA30EF209944C12BFB43805D72306F36C642408794DC3D428586F5486FD45`.

`build/` and `Artifacts/` remain ignored and were not staged. Protected untracked Cubase files, source images, and milestone prompts were neither modified nor staged. Representative hashes remain unchanged:

| Protected untracked file | Bytes | SHA-256 |
|---|---:|---|
| `CubaseTest/DeepPluckTest.cpr` | 785,571 | `A039DBBF9F60E8A8C61AC11C5CD63527CCD2EE5FF9935020CC0071B93AF36C5B` |
| source GUI image | 1,670,004 | `1C974D7D7820031BE8CB09FB1B2CE656FE4F6F80E344CC9F416155580C5FD219` |
| V0.10.0 master prompt | 66,004 | `627E27F9F9C0DB59576865A6A4B6FED43AC3DE5A4543CF6D60DD2B177B6953EA` |

No push was performed.

## 10. Documentation changed

- `README.md`: V0.10.2 status, fixed 1536 x 900 geometry, Filter/FX layouts, visual treatment, meter scale/gradient, automated coverage, Standalone label, Cubase checklist, confirmed environment, and fixed-size limitation;
- `ARCHITECTURE.md`: V0.10.2 ownership/version, compact page host, Cutoff exception, exact FX axes, button/glow/meter rendering contracts, and regression coverage;
- `AGENTS.md`: confirmed V0.10.2 reference environment;
- `CMakeLists.txt`: authoritative 0.10.2 version and milestone description;
- this implementation report.

## 11. Manual Cubase and listening checklist — open

Automation cannot claim the following:

1. Confirm Cubase recognizes V0.10.2 as the same instrument and exposes exactly sixty-two automation parameters in the unchanged order.
2. Restore representative V0.1.0-through-V0.10.1 projects, presets, states, and automation.
3. Confirm the complete 1536 x 900 interface fits the intended Cubase and Standalone workflows at Windows scaling 100%, 125%, and 150%.
4. Confirm Filter On, the large Cutoff, and the right-hand two-by-two grid read naturally during real use.
5. Confirm all FX Bypass/Position controls, the four rotary axes, and stacked Free/Sync/Division controls remain immediately legible.
6. Judge the subtle button relief and intermediate waveform/ADSR Amber glow on the real display; confirm neither becomes distracting during longer sessions.
7. Confirm the Teal-to-Cyan-to-Amber meter progression tracks both channels correctly, 0 dB remains below the top, and +6 dB uses the full height.
8. Confirm Hover Help, Random/Lock, preset workflows, FX order/Reset, Welcome, keyboard focus, and repeated editor open/close behavior.
9. Perform realtime playback, multiple-instance, project save/reopen, offline bounce, CPU, headroom, and musical listening checks.
10. Reconfirm that enabling/bypassing FX and changing order causes no unexpected loudness, tail, or stability regression.

V0.10.2 is automatable-complete; these manual host and perceptual checks remain the only open acceptance work.
