# DeepPluck V0.10.1 GUI Refinement — Implementation Report

Date: 2026-09-01

Branch: `master`

Starting HEAD: `e66a4ebc834bcf4f3909a33681ef0a17ca899b42`

Implementation commit: `2285a44fe4d75d720f247d41d15eed7212837604` — `fix: refine GUI alignment and control sizing`

## 1. Outcome

The complete automatable V0.10.1 Definition of Done passed. The milestone applies the requested GUI corrections to the completed V0.10.0 instrument and changes no DSP, processor, parameter, preset, state, automation, plugin identity, or bus behavior.

The fixed editor now has shared vertical label/control/value bands, one common 64 x 64 pixel rotary body size, aligned narrow FX Position fields, an indented preset action row, full-height output metering, explicit Master Random/Amount Hover Help, a clearer vector lock, and minimum-time ADSR segments that become vertical at the practical 0.001-second minimum.

Manual Cubase, listening, and display-scaling 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 V0.10.0 implementation and its tracked target mockup remained the visual and architectural base.

No file under `JUCE/` changed. No DSP, processor, parameter, preset, state, 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 corrections

- `SliderControl`, `ToggleControl`, and `ChoiceControl` reserve the same 24-pixel label band and the same control/value bands. Toggle and choice bodies are centered on the rotary-body axis.
- Every rotary body is bounded to exactly 64 x 64 pixels on the fixed V0.10 editor, including Master Tune, Output, Oscillators, MAIN, MODULATION, and FX.
- Chorus, Delay, and Reverb use equal fixed Bypass columns and equal 150-pixel Position wrappers. The visible choices are 138 pixels wide and occupy the same vertical column.
- The preset action row has one former-button-width indent; Save now begins under the preset selector at the former Save As position.
- Master Random and Amount have explicit descriptions delivered by the existing preference-gated Hover Help system.
- The stereo meter component spans the complete 112-pixel header height; its channel bars no longer add top/bottom outer insets.
- The Lock vector now has a closed rounded shackle, rectangular body, and visible keyhole.
- The ADSR display uses pure logarithmic time geometry. At 0.001 seconds, Attack has zero horizontal width before its rise and Decay/Release have zero horizontal width before their fall. Increasing a time widens only that segment; Sustain remains horizontal.

## 4. Automated GUI coverage and visual review

The `gui` suite now verifies:

- exact minimum-time Attack, Decay, and Release geometry and monotonic widening;
- the common 64-pixel rotary size for every APVTS rotary control;
- shared label and control-body axes for Oscillator 2, Filter, Transient, Noise, Modulation, Chorus, Delay, and Reverb;
- one narrow aligned FX Position column;
- preset action-row indentation;
- full-height output meter bounds;
- non-empty Master Random and Amount Hover Help;
- all earlier binding, routing, state-neutrality, preference, metering, and page contracts.

Fresh build-local PNG snapshots of MAIN, MODULATION, FX, and SETTINGS were generated by the test and visually reviewed. The V0.10.1 version label, corrected alignments, common rotary size, revised lock symbols, FX column, and full-height meter are present without visible overlap or clipping at the fixed test canvas.

## 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 configuration and builds used:

```powershell
cmake --fresh -S . -B build -G "Visual Studio 18 2026" -A x64
cmake --build build --config Debug --parallel
cmake --build build --config Release --parallel
```

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 0.10.1.

## 6. Final build and test results

| Configuration | Build | Compiler errors | New compiler warnings | CTest result |
|---|---|---:|---:|---:|
| Debug | pass | 0 | 0 | 28/28 pass, 53.53 s |
| Release | pass | 0 | 0 | 28/28 pass, 16.37 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 0.10.1)` is the single authoritative current version. The VST3 metadata, Standalone FileVersion/ProductVersion, generated JUCE macros, GUI version labels, and project-local copies all resolve to 0.10.1.

| Project-local artifact | Bytes | SHA-256 |
|---|---:|---|
| Debug VST3 inner binary | 28,402,176 | `5DBA919B77172022D58290C3600B2EAFECDD46A8F9169EE6EB018A249494089F` |
| Debug Standalone | 28,845,056 | `C182C137894D83ECE08268D18B1D2A980FBBF75DFA51B96C98A6BB20D0206BE2` |
| Release VST3 inner binary | 9,420,800 | `6F6B5C546E790834674DB1F8588DA2C4C15FBF5D3C60B4D46A02A26FAF0E7B1A` |
| Release Standalone | 9,440,768 | `B562BEE06E98E448FBD7478D5A49318928E8046688A3D4BF028D708C568A6A8B` |

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 process behind:

| Configuration | Window handle | Exit code |
|---|---:|---:|
| Debug | 1,050,764 | 0 |
| Release | 526,824 | 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`. No build or test installed or copied a plugin/application into a system directory. The pre-existing system VST3 remains byte-identical to the V0.10.0 recorded baseline:

| Existing system file | Bytes | SHA-256 |
|---|---:|---|
| VST3 inner binary | 7,870,464 | `288F1BC88BBB8FCD131DA089846C3ED99D5E554B77EA9DA4A97EA18E2000FDC3` |
| `moduleinfo.json` | 1,086 | `E42CA30EF209944C12BFB43805D72306F36C642408794DC3D428586F5486FD45` |

`build/` and `Artifacts/` remain ignored; `git ls-files` reports zero tracked entries for both. 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`: V0.10.1 status, visible corrections, automated coverage, confirmed environment, Standalone label, Cubase checklist, and fixed-size limitation;
- `ARCHITECTURE.md`: V0.10.1 architecture/version, shared layout bands, FX columns, header behavior, ADSR geometry, and test contract;
- `AGENTS.md`: confirmed V0.10.1 reference environment;
- `CMakeLists.txt`: authoritative 0.10.1 version and milestone description;
- this implementation report.

## 11. Manual Cubase and listening checklist — open

Automation cannot claim the following:

1. Confirm Cubase recognizes V0.10.1 as the same instrument and still exposes exactly sixty-two automation parameters in the unchanged order.
2. Restore representative V0.1.0-through-V0.10.0 projects, presets, states, and automation.
3. Compare MAIN, MODULATION, FX, and SETTINGS at Windows scaling 100%, 125%, and 150%.
4. Confirm all labels and switch bodies align visually, every rotary is equally sized, and the FX Position fields form one narrow vertical column.
5. Confirm the revised Lock icon is immediately recognizable in all compact and full-height panels.
6. Confirm Hover Help appears for Master Random and Amount when enabled and remains absent when disabled.
7. Confirm the output meter uses the full intended height and reacts correctly during playback.
8. Confirm minimum-time Amp and Filter Attack/Decay/Release segments look vertical and longer times widen naturally.
9. Exercise preset navigation/save/delete/refresh/folder, all Random/Lock pairs, FX order/Reset, Welcome, keyboard focus, and repeated editor open/close.
10. Perform realtime playback, multiple-instance, project save/reopen, offline bounce, CPU, headroom, and musical listening checks.

V0.10.1 is automatable-complete; these manual host and perceptual checks remain the only open acceptance work.
