status: human_needed
score: 4/4 must-haves verified
human_verification:
- test: "Load Kimai dashboard and verify heatmap renders identically to v1.0"
expected: "Cells colored with 4-shade green scale, tooltip on hover shows date/hours/entries, click navigates to timesheet, stats row present, filter dropdown works, window resize re-renders"
why_human: "Visual regression cannot be verified programmatically -- SVG structure matches but pixel-level rendering needs eyeballs"
- test: "Open browser console on dashboard page"
expected: "No JavaScript errors. typeof KimaiHeatmap.init === 'function'"
why_human: "Runtime behavior in actual Kimai environment with Symfony asset pipeline"

# Phase 6: Renderer Architecture Verification Report
**Phase Goal:** Existing year-view heatmap works identically but through a mode-dispatched renderer system ready for new visualization modes
**Verified:** 2026-04-09T10:00:00Z
**Status:** human_needed
**Re-verification:** No -- initial verification
## Goal Achievement
### Observable Truths
| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Year-view heatmap renders identically to v1.0 (no visual regression) | VERIFIED (automated) | YearModeRenderer produces same SVG structure: same cell classes (heatmap-cell, heatmap-empty, heatmap-weekend), same tooltip HTML, same color scale, same cell-size computation. 124/124 tests pass including migrated heatmap/interaction tests. Visual confirmation pending human. |
| 2 | Tooltip, color scale, and cell click handler extracted as shared utilities reusable by any renderer | VERIFIED | `shared/tooltip.ts` exports createTooltip/showTooltip/hideTooltip. `shared/color-scale.ts` exports buildColorScale with DisplayMetric param. YearModeRenderer imports all from shared/ paths. |
| 3 | HeatmapState object tracks mode, display metric, and filters -- UI changes flow through state | VERIFIED | `state.ts` defines HeatmapState with mode/metric/filters/weekStart/data. `createInitialState('monday')` returns defaults. heatmap.ts creates state, passes via RenderContext to renderer. Filter changes mutate `state.filters.projectId` then call `doRender()`. |
| 4 | Adding a new visualization mode requires only implementing ModeRenderer interface and registering it | VERIFIED | ModeRenderer interface in `renderers/types.ts` with `mode: string`, `render(ctx)`, optional `destroy()`. Registry in `renderers/registry.ts` with registerRenderer/getRenderer. heatmap.ts dispatches via `getRenderer(state.mode)`. Adding a mode = implement interface + call `registerRenderer(new FooRenderer())`. |
**Score:** 4/4 truths verified (automated checks)
### Required Artifacts
| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `assets/src/renderers/year.ts` | YearModeRenderer implementing ModeRenderer | VERIFIED | 131 lines, implements full year heatmap rendering with shared utility imports |
| `assets/src/renderers/types.ts` | ModeRenderer interface, RenderContext type | VERIFIED | Exports both interfaces, includes emptyMessage field |
| `assets/src/renderers/registry.ts` | Renderer registration and lookup | VERIFIED | registerRenderer/getRenderer/clearRegistry exported |
| `assets/src/state.ts` | HeatmapState creation | VERIFIED | HeatmapState interface + createInitialState factory |
| `assets/src/shared/tooltip.ts` | Tooltip lifecycle functions | VERIFIED | createTooltip/showTooltip/hideTooltip exported |
| `assets/src/shared/color-scale.ts` | Color scale factory | VERIFIED | buildColorScale with DisplayMetric support, FALLBACK_COLORS |
| `assets/src/shared/stats.ts` | Stats calculation and rendering | VERIFIED | calculateStreak/calculateStats/renderStats/HeatmapStats |
| `assets/src/shared/date-utils.ts` | Date grid utilities | VERIFIED | buildDateMap/generateCells/getWeekInterval/getDayLabels/DayCell + format constants |
| `assets/src/types.ts` | Extended type definitions | VERIFIED | Added DisplayMetric, HeatmapMode, FilterState alongside existing interfaces |
| `assets/src/heatmap.ts` | Slim orchestrator | VERIFIED | 128 lines (down from 413), imports from registry/state/shared modules |
| `Resources/public/heatmap.js` | Built IIFE bundle with KimaiHeatmap.init | VERIFIED | 38.9kb minified, KimaiHeatmap global present |
### Key Link Verification
| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| heatmap.ts | renderers/registry.ts | `getRenderer(state.mode)` | WIRED | Line 45: `const renderer = getRenderer(state.mode)` |
| heatmap.ts | renderers/year.ts | `registerRenderer(new YearModeRenderer())` | WIRED | Line 9: module-level registration |
| heatmap.ts | state.ts | `createInitialState(weekStart)` | WIRED | Line 23: state creation |
| heatmap.ts | shared/stats.ts | `renderStats(container, state.data.days)` | WIRED | Line 55: stats rendering in doRender() |
| renderers/year.ts | shared/tooltip.ts | imports createTooltip/showTooltip/hideTooltip | WIRED | Lines 5, 116, 119: full tooltip lifecycle used |
| renderers/year.ts | shared/color-scale.ts | imports buildColorScale | WIRED | Line 6, 40: scale built and used for cell fill |
| renderers/year.ts | shared/date-utils.ts | imports generateCells, buildDateMap, getWeekInterval | WIRED | Lines 7-10, 34-37: all used for cell generation |
| renderers/types.ts | types.ts | imports HeatmapData, HeatmapConfig | WIRED | Line 1 |
| renderers/types.ts | state.ts | imports HeatmapState | WIRED | Line 2 |
### Behavioral Spot-Checks
| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Full test suite passes | `npx vitest run` | 18 files, 124 tests, all passing | PASS |
| esbuild produces valid bundle | `npm run build` | 38.9kb output, no errors | PASS |
| KimaiHeatmap global in bundle | grep KimaiHeatmap in bundle | Found | PASS |
| Old functions removed from heatmap.ts | grep renderHeatmap/buildDateMap/FALLBACK_COLORS | 0 matches | PASS |
| heatmap.ts is slim | wc -l | 128 lines (down from 413) | PASS |
### Requirements Coverage
No requirement IDs assigned to this phase (architectural enabler). All v1.1 features depend on this refactor.
### Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| None found | - | - | - | - |
No TODOs, FIXMEs, placeholders, or stub patterns found in any phase 6 source files.
### Human Verification Required
### 1. Visual Regression Check
**Test:** Build dev bundle (`npm run build:dev`), start local Kimai, navigate to dashboard
**Expected:** Heatmap renders identically to v1.0: green-shaded cells, tooltip on hover with date/hours/entries, click navigates to timesheet with date filter, stats row (streak/total/avg/busiest), filter dropdown works, window resize re-renders correctly
**Why human:** SVG structure verified programmatically via tests, but actual visual rendering in browser with CSS and Kimai theme integration requires eyeballs
### 2. Runtime Console Check
**Test:** Open browser console on Kimai dashboard with heatmap loaded
**Expected:** No JavaScript errors. `typeof KimaiHeatmap.init` returns `'function'`
**Why human:** Verifying runtime behavior in actual Symfony/Kimai environment with asset pipeline
### Gaps Summary
No automated gaps found. All truths verified, all artifacts exist and are substantive, all key links wired. The only remaining verification is visual regression in a running Kimai instance (human verification items above).
