| 6 | + |
| 7 | +| Check | Status | Evidence | |
| 8 | +| --- | --- | --- | |
| 9 | +| Current branch | PASS | `git branch --show-current` returned `main`. | |
| 10 | +| Expected branch | PASS | Required branch is `main`. | |
| 11 | + |
| 12 | +## Executive Finding |
| 13 | + |
| 14 | +Recommendation: **DEPRECATE**. |
| 15 | + |
| 16 | +`palette_source_swatches` is requested by the live Colors page through the palette repository snapshot path, and it contributes to visible output through the Colors `Repository Tables` panel (`Source Swatches838`). It does **not** affect the current generated Picker Preview grid, project swatch editing, symbol-free validation, import/export, or save/load behavior. Current source-browser UI controls are absent, and current harmony matching is supplied by generated picker swatches even when the user selects source-based match modes. |
| 17 | + |
| 18 | +Do not remove the table in this PR. A removal PR should first remove or replace the dead source-browser and source-harmony code paths, then update DB Viewer grouping and tests. |
| 19 | + |
| 20 | +## Runtime Trace Evidence |
| 21 | + |
| 22 | +Targeted Playwright/Chromium trace opened: |
| 23 | + |
| 24 | +- `/toolbox/colors/index.html` |
| 25 | +- `/toolbox/colors/index.html?source=empty` |
| 26 | + |
| 27 | +The trace captured palette API calls, DOM state, grid hexes, edit/save behavior, and reload behavior. |
| 28 | + |
| 29 | +### Normal Source Rows |
| 30 | + |
| 31 | +| Runtime item | Observed value | |
| 32 | +| --- | --- | |
| 33 | +| Page | `/toolbox/colors/index.html` | |
| 34 | +| Source controls rendered | `0` for `[data-palette-source-select]`, `[data-palette-source-search]`, `[data-palette-source-pin-all]`, `[data-palette-source-list]` | |
| 35 | +| Initial grid count | `24` | |
| 36 | +| First 12 grid hexes | `#245F34`, `#34813E`, `#4C9C4D`, `#80B65C`, `#AFC082`, `#D6CEA2`, `#A36E44`, `#43633A`, `#102A17`, `#1F4D25`, `#346B35`, `#5D8A3E` | |
| 37 | +| Rendered source table output | `Source Swatches838` | |
| 38 | +| Add picker swatch | Project count changed from `0` to `1`; selected swatch `Nature Forest Full Green #245F34` | |
| 39 | +| Reload after add | Project count remained `1`; `Source Swatches838` remained visible | |
| 40 | +| Snapshot source values | `sourcePaletteRecordCount=838`, `sourcePaletteOptions=11`, `palette_source_swatches rows=838` | |
| 41 | + |
| 42 | +### Empty Source Rows |
| 43 | + |
| 44 | +| Runtime item | Observed value | |
| 45 | +| --- | --- | |
| 46 | +| Page | `/toolbox/colors/index.html?source=empty` | |
| 47 | +| Source controls rendered | `0` | |
| 48 | +| Initial grid count | `24` | |
| 49 | +| First 12 grid hexes | Same as normal source rows: `#245F34`, `#34813E`, `#4C9C4D`, `#80B65C`, `#AFC082`, `#D6CEA2`, `#A36E44`, `#43633A`, `#102A17`, `#1F4D25`, `#346B35`, `#5D8A3E` | |
| 50 | +| Rendered source table output | `Source Swatches0` | |
| 51 | +| Add picker swatch | Project count changed from `0` to `1`; selected swatch `Nature Forest Full Green #245F34` | |
| 52 | +| Snapshot source values | `sourcePaletteRecordCount=0`, `sourcePaletteOptions=0`, `palette_source_swatches rows=0` | |
| 53 | + |
| 54 | +Conclusion: emptying source rows changes the diagnostic/table-count output, but not the generated grid. |
| 55 | + |
| 56 | +### Harmony Runtime Trace |
| 57 | + |
| 58 | +The trace selected a picker swatch, then switched Color Harmony Schemes Match to `All Sources Closest Match` and `Current Source Closest Match`. |
| 59 | + |
| 60 | +| Source mode | Match mode | Rendered output | |
| 61 | +| --- | --- | --- | |
| 62 | +| Normal source rows | All Sources Closest Match | `Showing 1 Complementary colors from All Sources Closest Match.` First title: `Complementary Nature Forest Full Orange #6F4B2E`. | |
| 63 | +| Empty source rows | All Sources Closest Match | Same rendered output: `Complementary Nature Forest Full Orange #6F4B2E`. | |
| 64 | +| Normal source rows | Current Source Closest Match | `Showing 1 Complementary colors from Current Source Closest Match.` First title: `Complementary Nature Forest Full Orange #6F4B2E`. | |
| 65 | +| Empty source rows | Current Source Closest Match | Same rendered output: `Complementary Nature Forest Full Orange #6F4B2E`. | |
| 66 | + |
| 67 | +Conclusion: current harmony output does not depend on `palette_source_swatches` because `toolbox/colors/colors.js` passes generated picker swatches from `currentHarmonyMatchSwatches()` into `repository.createHarmonySuggestions()`. In `harmonyForSwatch()`, provided match swatches win over source palette rows. |
| 68 | + |
| 69 | +## Page Requests |
| 70 | + |
| 71 | +| Page | Runtime request evidence | |
| 72 | +| --- | --- | |
| 73 | +| `toolbox/colors/index.html` | Requests `/api/toolbox/palette/repositories` and repeated `/api/toolbox/palette/repositories/{id}/methods/getSnapshot`; snapshot responses include source count/options/table data. | |
| 74 | +| `toolbox/colors/index.html?source=empty` | Same page route with test option; confirms grid behavior without source rows. | |
| 75 | + |
| 76 | +No current Colors page request directly called the `listSourceSwatches` repository method during the trace. |
| 77 | + |
| 78 | +## API / Service Methods Reading Source Rows |
| 79 | + |
| 80 | +| Method/path | Runtime role | Source-row effect | |
| 81 | +| --- | --- | --- | |
| 82 | +| `createProjectWorkspacePaletteRepository()` | Repository creation reads `loadedMockDbTables.palette_source_swatches` into `sourcePaletteRows`. | Active initialization read. | |
| 83 | +| `getSnapshot()` | Returns `sourcePaletteOptions`, `sourcePaletteRecordCount`, `tableCounts`, and `tables`, all derived from `sourcePaletteRows`/`getTables()`. | Active read; visible only through Repository Tables count on current page. | |
| 84 | +| `sourcePaletteOptions()` | Builds source option metadata from `sourcePaletteRows`. | Dead for current UI because source select is absent; still returned in snapshots. | |
| 85 | +| `listSourceSwatches()` | Reads source rows by source/filter/sort. | Dead for current Colors page trace; no request to this method occurred. | |
| 86 | +| `createHarmonySuggestions()` | Builds `sourcePaletteData` from `sourcePaletteOptions()` and `listSourceSwatches()` before calling `harmonyForSwatch()`. | Dead read in current UI because provided generated picker `matchSwatches` override source palettes. | |
| 87 | +| `getTables()` | Emits `palette_source_swatches` rows and table counts. | Active diagnostic/table-count read; also included in persistence snapshots. | |
| 88 | + |
| 89 | +## UI Consumer List |
| 90 | + |
| 91 | +| UI component | Consumes `palette_source_swatches` data? | Evidence | |
| 92 | +| --- | --- | --- | |
| 93 | +| Repository Tables panel | YES | `renderTables()` consumes `snapshot.tableCounts`; `displayColorsTableName()` maps `palette_source_swatches` to `Source Swatches`; runtime showed `Source Swatches838`. | |
| 94 | +| Source browser controls | NO in current page | HTML has no source select/search/pin/list nodes; trace source control count was `0`; `renderSourceOptions()` and `renderSourceSwatches()` return early. | |
| 95 | +| Picker Preview grid | NO | Normal and empty-source runs both rendered 24 grid swatches with the same first 12 hexes. Grid is generated from curated arrays in `toolbox/colors/colors.js`. | |
| 96 | +| Color Harmony Schemes | NO for current behavior | Source rows are read by service helper code, but generated picker swatches are passed as `matchSwatches` and determine rendered harmony output. Normal and empty-source traces matched. | |
| 97 | +| Project Swatches list/editing | NO | Add/update/remove/tag behavior reads/writes `palette_colors` through active project swatches, not `palette_source_swatches`. | |
| 98 | +| Import/export | NO | Current UI does not expose import/export; repository `loadActiveProjectPalettePayload()` validates and loads `tools.palette-browser.swatches` only. | |
| 99 | +| Save/load persistence | INDIRECT / redundant | Palette save operations persist current adapter tables through `getTables()`, including unchanged source rows, but source rows do not determine project swatch save/load results. | |
| 100 | + |
| 101 | +## Requested Behavior Questions |
| 102 | + |
| 103 | +| Question | Finding | |
| 104 | +| --- | --- | |
| 105 | +| Does `palette_source_swatches` contribute to rendered Colors page output? | YES, through Repository Tables row `Source Swatches838`; not through source browser controls. | |
| 106 | +| Does it affect grid rendering? | NO. Empty-source trace produced the same grid count and first grid hexes. | |
| 107 | +| Does it affect import/export? | NO current import/export UI; repository payload loading uses active project swatches only. | |
| 108 | +| Does it affect palette editing? | NO for current manual/picker editing. Picker add/save uses generated swatch data and `palette_colors`. | |
| 109 | +| Does it affect save operations? | Not functionally. Saves persist full palette table state including unchanged source rows, but source rows do not change saved project swatches. | |
| 110 | + |
| 111 | +## Dead Read Findings |
| 112 | + |
| 113 | +| Dead read | Evidence | |
| 114 | +| --- | --- | |
| 115 | +| `sourcePaletteOptions` in current Colors UI | Returned in snapshots but no source select is rendered. | |
| 116 | +| `renderSourceOptions()` / `renderSourceSwatches()` source UI path | Functions exist, but no matching DOM nodes exist in `toolbox/colors/index.html`; runtime source control count was `0`. | |
| 117 | +| `createHarmonySuggestions()` source palette data build | Service constructs source palette data, but current UI passes generated picker `matchSwatches`, so `harmonyForSwatch()` uses generated swatches instead. Empty-source and normal-source harmony output matched. | |
| 118 | +| `listSourceSwatches()` API method for current page | No runtime request to the repository `listSourceSwatches` method appeared in the trace. | |
| 119 | + |
| 120 | +## Dead Write Findings |
| 121 | + |
| 122 | +| Dead/redundant write | Evidence | |
| 123 | +| --- | --- | |
| 124 | +| Persisting unchanged `palette_source_swatches` during palette edits | `pinSourceSwatch`/save paths persist repository tables through `getTables()`, which includes unchanged source rows. This keeps adapter snapshots complete, but the current edit/save result does not depend on source row content. | |
| 125 | + |
| 126 | +## Removal Path |
| 127 | + |
| 128 | +1. Remove or replace source-browser code paths in `toolbox/colors/colors.js`: `renderSourceOptions()`, `renderSourceSwatches()`, source sort/size/pin-all handlers, and source-only state. |
| 129 | +2. Remove `sourcePaletteOptions`, `listSourceSwatches`, and source-data preloading from `createHarmonySuggestions()` unless a real source-backed harmony UX is restored. |
| 130 | +3. Update `getSnapshot()` to omit source options/record count/tables from the Colors runtime snapshot, or move them to an admin-only diagnostics endpoint. |
| 131 | +4. Remove `palette_source_swatches` from `PALETTE_TOOL_TABLES`, mock DB schemas, DB Viewer Palette grouping, and seed generation. |
| 132 | +5. Update Playwright/repository tests that still assert source table behavior. |
| 133 | + |
| 134 | +Until that cleanup is intentionally scoped, keep the physical table but mark it as deprecated/legacy source-browser data. |
