-**Priority**: 🔴 CRITICAL - Blocking entire build pipeline
+**Issue**: E2E workflow contains redundant build steps and inefficiencies
+**Status**: Analysis Complete - Ready for Implementation
+**Priority**: 🟡 MEDIUM - Performance optimization opportunity
 **Created**: 2026-01-26

-## 🎯 Scope Summary
+## 🎯 Executive Summary
 
-This specification covers **ALL 7 GitHub Actions workflows** that use Go:
+The E2E workflow `.github/workflows/e2e-tests.yml` builds and tests the application efficiently with proper sharding, but contains **4 critical redundancies** that waste CI resources:
 
-| # | Workflow | Current Go Version | Status | Action Required |
-|---|----------|-------------------|--------|-----------------|
-| 1 | `quality-checks.yml` | 1.25.6 ✅ | Correct version | Add `GOTOOLCHAIN: auto` |
-| 2 | `codeql.yml` | 1.25.6 ✅ | Correct version | Add `GOTOOLCHAIN: auto` |
-| 3 | `benchmark.yml` | 1.25.6 ✅ | Correct version | Add `GOTOOLCHAIN: auto` |
-| 4 | `codecov-upload.yml` | 1.25.6 ✅ | Correct version | Add `GOTOOLCHAIN: auto` |
-| 5 | `e2e-tests.yml` | 1.21 ⚠️ | **OUTDATED!** | Update to 1.25.6 + Add `GOTOOLCHAIN: auto` |
-| 6 | `nightly-build.yml` | Hardcoded ⚠️ | No global env | Create env section with `GOTOOLCHAIN: auto` |
-| 7 | `release-goreleaser.yml` | 1.25.6 ✅ | Correct version | Add `GOTOOLCHAIN: auto` |
+| Issue | Location | Impact | Fix Complexity |
+|-------|----------|--------|----------------|
+| 🔴 **Docker rebuild** | Line 157 | 30-60s per shard (×4) | LOW - Remove flag |
+| 🟡 **Duplicate npm installs** | Lines 81, 205, 215 | 20-30s per shard (×4) | MEDIUM - Cache better |
+| 🟡 **Unnecessary pre-builds** | Lines 90, 93 | 30-45s in build job | LOW - Remove steps |
+| 🟢 **Browser install caching** | Line 201 | 5-10s per shard (×4) | LOW - Already implemented |
 
-**Why All 7?** Initial analysis only covered 2 workflows. Supervisor review identified 5 additional workflows that would fail without this fix, including a CRITICAL issue in `e2e-tests.yml` using outdated Go 1.21.
+**Total Waste per Run**: ~2-4 minutes (120-240 seconds)
+**Frequency**: Every PR with frontend/backend/test changes
+**Cost**: ~$0.10-0.20 per run (GitHub-hosted runners)

-### Root Cause Identified
+### Jobs Breakdown
 
-**The issue is NOT an invalid Go version.** Go 1.25.6 is a valid, released version (verified via `https://go.dev/dl/`).
+| Job | Dependencies | Parallelism | Duration | Purpose |
+|-----|--------------|-------------|----------|---------|
+| `build` | None | 1 instance | ~2-3 min | Build Docker image once |
+| `e2e-tests` | `build` | 4 shards | ~5-8 min | Run tests with coverage |
+| `merge-reports` | `e2e-tests` | 1 instance | ~30-60s | Combine HTML reports |
+| `comment-results` | `e2e-tests`, `merge-reports` | 1 instance | ~10s | Post PR comment |
+| `upload-coverage` | `e2e-tests` | 1 instance | ~30-60s | Merge & upload to Codecov |
+| `e2e-results` | `e2e-tests` | 1 instance | ~5s | Final status gate |
 
-**The actual problem**: The pre-commit framework sets `GOTOOLCHAIN=local` by default, which prevents automatic toolchain upgrades. When CI runs with an older Go version (1.21.13), it cannot upgrade to the required 1.25.6.
-
-**Evidence**:
-- `backend/.venv/lib/python3.12/site-packages/pre_commit/languages/golang.py` explicitly sets `GOTOOLCHAIN=local`
-- CI environment has Go 1.21.13 installed system-wide
-- Workspace requires Go 1.25.6 (go.work, go.mod)
-- Docker builds use Go 1.25.6 successfully
-- Local environment with Go 1.25.6 works correctly
-
-### Current Configuration Audit
-
-| File | Go Version | Status |
-|------|------------|--------|
-| `go.work` | 1.25.6 | ✅ Correct |
-| `backend/go.mod` | 1.25.6 | ✅ Correct |
-| `Dockerfile` (gosu-builder) | 1.25-trixie | ✅ Correct |
-| `Dockerfile` (backend-builder) | 1.25-trixie | ✅ Correct |
-| `Dockerfile` (caddy-builder) | 1.25-trixie | ✅ Correct |
-| `Dockerfile` (crowdsec-builder) | 1.25.6-trixie | ✅ Correct (pinned via Renovate) |
-| `.github/workflows/quality-checks.yml` | 1.25.6 | ✅ Correct |
-| `.github/workflows/docker-build.yml` | (uses Dockerfile) | ✅ Correct |
-| `.github/workflows/codeql.yml` | 1.25.6 | ✅ Correct |
-| `Makefile` (install-go comment) | 1.25.5 | ⚠️ Outdated comment |
-
-**Conclusion**: Most version declarations are correctly set to 1.25.6. However, **CRITICAL FINDING**: `e2e-tests.yml` uses outdated Go 1.21, which MUST be updated to 1.25.6. Additionally, the CI environment's inability to upgrade due to `GOTOOLCHAIN=local` affects all 7 workflows.
-
-**Critical Issues Found During Analysis**:
-1. ⚠️ **e2e-tests.yml**: Uses Go 1.21 (outdated) - MUST update to 1.25.6
-2. ⚠️ **nightly-build.yml**: No global env section - should consolidate version management
-3. ✅ Other 5 workflows: Already use Go 1.25.6 but need GOTOOLCHAIN setting
+**✅ Parallelism is correct**: 4 shards run different test subsets simultaneously.
 
 ---
 
----
+## 🔍 Detailed Analysis
 
-## Solution Strategy
+### 1. Docker Image Lifecycle
 
-### Option A: Set GOTOOLCHAIN=auto in CI (RECOMMENDED)
+#### Current Flow
 
-**Approach**: Override `GOTOOLCHAIN=local` in GitHub Actions workflows to allow automatic toolchain upgrades.
-
-**Rationale**:
-- **Minimal changes**: Only workflow files need modification
-- **Future-proof**: Allows automatic upgrades when new Go versions are released
-- **CI best practice**: GitHub Actions should always use the version specified in workflow
-- **Matches Go team recommendation**: `GOTOOLCHAIN=auto` is the default for most Go projects
-- **No impact on local development**: Developers with correct Go version unaffected
-
-**Implementation**:
-1. Add `GOTOOLCHAIN: auto` to env section in workflow files
-2. Files to modify:
-   - `.github/workflows/quality-checks.yml`
-   - `.github/workflows/codeql.yml`
-   - Any other workflow that invokes Go commands
-
-**Risk Assessment**: ⬇️ LOW
-- Change is isolated to CI environment
-- Does not affect Docker builds (already working)
-- Does not affect local development (already working)
-- Reversible if issues arise
-
----
-
-### Option B: Update Pre-commit Configuration (NOT RECOMMENDED)
-
-**Approach**: Attempt to override pre-commit's `GOTOOLCHAIN=local` setting.
-
-**Why Not Recommended**:
-- Pre-commit's golang handler is hardcoded to set `GOTOOLCHAIN=local`
-- Would require forking pre-commit or monkey-patching
-- High maintenance burden
-- Doesn't address CI environment directly
-- Complex and fragile solution
-
----
-
-### Option C: Downgrade Go Version Requirements (NOT RECOMMENDED)
-
-**Approach**: Revert go.work and go.mod to Go 1.21.x.
-
-**Why Not Recommended**:
-- **Security risk**: Go 1.21 is older and missing security patches
-- **Blocks dependency updates**: Many modern Go packages require 1.23+
-- **Regression**: Reverses intentional upgrade decision
-- **Docker already uses 1.25.6**: Would create inconsistency
-- **Go 1.25.6 is stable**: No reason to downgrade
-
----
-
-## Implementation Plan (Option A - Recommended)
-
-### Phase 1: Update GitHub Actions Workflows
-
-**Files to Modify**: 7 workflow files (ALL workflows that use Go)
-
-#### 1. `.github/workflows/quality-checks.yml`
-
-**Location**: Line 18 (env section)
-**Current Go Version**: 1.25.6 ✅
-
-**Change**:
 ```yaml
-env:
-  GO_VERSION: '1.25.6'
-  NODE_VERSION: '24.12.0'
-  GOTOOLCHAIN: auto  # ← ADD THIS LINE
+# BUILD JOB (Lines 73-118)
+- name: Build frontend
+  run: npm run build
+  working-directory: frontend               # ← REDUNDANT (Dockerfile does this)
+
+- name: Build backend
+  run: make build                           # ← REDUNDANT (Dockerfile does this)
+
+- name: Build Docker image
+  uses: docker/build-push-action@v6
+  with:
+    push: false
+    load: true
+    tags: charon:e2e-test
+    cache-from: type=gha                    # ✅ Good - uses cache
+    cache-to: type=gha,mode=max
+
+- name: Save Docker image
+  run: docker save charon:e2e-test -o charon-e2e-image.tar
+
+- name: Upload Docker image artifact
+  uses: actions/upload-artifact@v6
+  with:
+    name: docker-image
+    path: charon-e2e-image.tar
 ```
 
-**Justification**: Allows setup-go action to download and use Go 1.25.6 even if system has older version.
-
----
-
-#### 2. `.github/workflows/codeql.yml`
-
-**Location**: Line 15 (env section)
-**Current Go Version**: 1.25.6 ✅
-
-**Change**:
 ```yaml
-env:
-  GO_VERSION: '1.25.6'
-  GOTOOLCHAIN: auto  # ← ADD THIS LINE
+# E2E-TESTS JOB - PER SHARD (Lines 142-157)
+- name: Download Docker image
+  uses: actions/download-artifact@v7
+  with:
+    name: docker-image                      # ✅ Good - reuses artifact
+
+- name: Load Docker image
+  run: docker load -i charon-e2e-image.tar  # ✅ Good - loads pre-built image
+
+- name: Start test environment
+  run: |
+    docker compose -f .docker/compose/docker-compose.playwright.yml up -d --build
+    #                                                                    ^^^^^^^^
+    #                                                                    🔴 PROBLEM!
 ```
 
-**Justification**: Ensures CodeQL analysis uses correct Go version for accurate results.
+#### 🔴 Critical Issue: `--build` Flag (Line 157)
 
----
-
-#### 3. `.github/workflows/benchmark.yml`
-
-**Location**: Line 21 (env section)
-**Current Go Version**: 1.25.6 ✅
-
-**Change**:
-```yaml
-env:
-  GO_VERSION: '1.25.6'
-  GOTOOLCHAIN: auto  # ← ADD THIS LINE
-```
-
-**Justification**: Benchmark tests compile and run Go code. Requires correct toolchain version for accurate performance measurements.
-
----
-
-#### 4. `.github/workflows/codecov-upload.yml`
-
-**Location**: Line 17 (env section)
-**Current Go Version**: 1.25.6 ✅
-
-**Change**:
-```yaml
-env:
-  GO_VERSION: '1.25.6'
-  NODE_VERSION: '24.12.0'
-  GOTOOLCHAIN: auto  # ← ADD THIS LINE
-```
-
-**Justification**: Runs backend tests with coverage collection. Must use correct Go version to ensure accurate coverage metrics.
-
----
-
-#### 5. `.github/workflows/e2e-tests.yml`
-
-**Location**: Line 60 (env section)
-**Current Go Version**: 1.21 ⚠️ **OUTDATED!**
-
-**Change**:
-```yaml
-env:
-  NODE_VERSION: '20'
-  GO_VERSION: '1.25.6'  # ← UPDATE FROM 1.21
-  GOTOOLCHAIN: auto     # ← ADD THIS LINE
-  REGISTRY: ghcr.io
-  IMAGE_NAME: ${{ github.repository_owner }}/charon
-```
-
-**Justification**: E2E tests build Docker images containing Go backend. The outdated 1.21 version causes build failures. This is a CRITICAL fix.
-
----
-
-#### 6. `.github/workflows/nightly-build.yml`
-
-**Location**: Line 17 (existing env section)
-**Current State**: Has global env section with registry config, missing Go version variables
-
-**Change** (ADD TO EXISTING):
-```yaml
-env:
-  GO_VERSION: '1.25.6'      # ← ADD THIS LINE
-  NODE_VERSION: '24.12.0'   # ← ADD THIS LINE (consistent with other workflows)
-  GOTOOLCHAIN: auto         # ← ADD THIS LINE
-  GHCR_REGISTRY: ghcr.io    # ← KEEP EXISTING
-  DOCKERHUB_REGISTRY: docker.io  # ← KEEP EXISTING
-  IMAGE_NAME: wikid82/charon     # ← KEEP EXISTING
-```
-
-**Justification**: Nightly build workflow already has an env section with registry config. We need to ADD Go-related variables to it, not create a new section.
-
----
-
-#### 7. `.github/workflows/release-goreleaser.yml`
-
-**Location**: Line 13 (env section)
-**Current Go Version**: 1.25.6 ✅
-
-**Change**:
-```yaml
-env:
-  GO_VERSION: '1.25.6'
-  NODE_VERSION: '24.12.0'
-  GOTOOLCHAIN: auto  # ← ADD THIS LINE
-```
-
-**Justification**: Production releases must use exact Go version specified. Prevents release failures due to CI environment mismatches.
-
----
-
-### Verification Command
-
-**Before Implementation**:
-```bash
-# Count workflows using setup-go
-grep -l "setup-go" .github/workflows/*.yml | wc -l
-# Expected: 7
-```
-
-**After Implementation**:
-```bash
-# Verify all Go workflows have GOTOOLCHAIN: auto
-grep -l "GOTOOLCHAIN: auto" .github/workflows/*.yml | wc -l
-# Expected: 7
-
-# List workflows with GOTOOLCHAIN settings
-grep -l "GOTOOLCHAIN: auto" .github/workflows/*.yml
-# Should show all 7 workflow files
-```
-
----
-
-### Phase 2: Update Makefile Comment (Optional Cleanup)
-
-**File**: `Makefile`
-
-**Location**: Line 46 (install-go comment)
-
-**Change**:
-```makefile
-# Install Go 1.25.6 system-wide and setup GOPATH/bin
-install-go:
-	@echo "Installing Go 1.25.6 and gopls (requires sudo)"
-	sudo ./scripts/install-go-1.25.6.sh
-```
-
-**Note**: This is a comment-only change for consistency. Script may not exist or need updating.
-
----
-
-### Phase 3: Verification & Testing
-
-#### Verification Steps
-
-1. **Verify Workflow Syntax**
-   ```bash
-   # Check YAML validity
-   yamllint .github/workflows/quality-checks.yml
-   yamllint .github/workflows/codeql.yml
-   ```
-
-2. **Test CI Build**
-   - Push changes to a test branch
-   - Monitor GitHub Actions for successful builds
-   - Verify Go 1.25.6 is used in build logs
-
-3. **Verify Docker Builds**
-   ```bash
-   # Ensure Docker builds still work
-   make docker-build-versioned
-   ```
-
-4. **Test Local Development**
-   ```bash
-   # Ensure local development unaffected
-   cd backend && go version
-   cd backend && go build -o bin/api ./cmd/api
-   ```
-
-#### Success Criteria
-
-- ✅ ALL 7 Go workflows complete without Go version errors:
-  - quality-checks.yml
-  - codeql.yml
-  - benchmark.yml
-  - codecov-upload.yml
-  - e2e-tests.yml (CRITICAL: version also updated to 1.25.6)
-  - nightly-build.yml
-  - release-goreleaser.yml
-- ✅ Backend builds successfully in CI
-- ✅ CodeQL analysis completes without errors
-- ✅ Docker image builds successfully
-- ✅ E2E tests pass with correct Go version
-- ✅ Nightly builds use consistent Go version
-- ✅ Release builds complete without toolchain errors
-- ✅ Local development environment unaffected
-- ✅ PR #550 can proceed
-
----
-
-## Risk Mitigation
-
-### Potential Issues
-
-1. **Issue**: `setup-go` action may not support `GOTOOLCHAIN` override
-   - **Mitigation**: `setup-go@v6` respects environment variables; tested in Go 1.20+
-   - **Fallback**: Explicitly set `GOTOOLCHAIN=auto` in workflow steps
-
-2. **Issue**: Older Go version cached in CI
-   - **Mitigation**: `setup-go` action's cache is version-specific; will download 1.25.6
-   - **Fallback**: Manually clear cache or use `cache: false` temporarily
-
-3. **Issue**: Pre-commit still enforces `GOTOOLCHAIN=local`
-   - **Mitigation**: This only affects local pre-commit hooks, not CI
-   - **Fallback**: Skip pre-commit in CI or run with `GOTOOLCHAIN=auto` override
-
----
-
-## Best Practices for Go Version Management
-
-### Recommendations for Future
-
-1. **Use `GOTOOLCHAIN=auto` by default in CI**
-   - Allows automatic upgrades to compatible Go versions
-   - Prevents version mismatch errors
-   - Aligns with Go team's recommendation
-
-2. **Keep Go version consistent across all files**
-   - go.work, go.mod, Dockerfile, CI workflows should all use same major.minor version
-   - Use Renovate to keep versions synchronized
-
-3. **Pin exact Go version in security-critical builds**
-   - Use `golang:1.25.6-trixie` (exact version) for production Docker images
-   - Use `golang:1.25-trixie` (latest patch) for development
-
-4. **Document Go version requirements**
-   - Add to README.md: "Requires Go 1.25.6 or later"
-   - Update CONTRIBUTING.md with setup instructions
-
-5. **Monitor Go releases**
-   - Subscribe to Go release notes: https://go.dev/dl/
-   - Plan upgrades within 1 month of stable release
-   - Test in development branch before merging to main
-
----
-
-## Alternative: GOTOOLCHAIN=auto by Default (Future Enhancement)
-
-**Proposal**: Set `GOTOOLCHAIN=auto` as repository default.
-
-**Method**: Create `.go-env` file or export in shell profile.
-
-**Benefits**:
-- Prevents version mismatch issues across environments
-- Aligns with Go's recommended default
-- Reduces CI configuration complexity
-
-**Drawbacks**:
-- Requires all developers to update local environment
-- May cause unexpected upgrades in local development
-- Not standard practice (most projects don't set this)
-
-**Recommendation**: ⏸️ DEFER - Implement Option A first, revisit if issues persist.

-## Decision Record
-
-**Decision**: Implement Option A - Set `GOTOOLCHAIN=auto` in GitHub Actions workflows
-
-**Rationale**:
-1. **Comprehensive fix**: Addresses all 7 workflows that use Go (not just 2)
-2. **Fixes critical version mismatch**: Updates e2e-tests.yml from Go 1.21 to 1.25.6
-3. **Minimal invasive changes**: Only 1-2 line additions per workflow file
-4. **Immediate resolution**: Unblocks PR #550 and future builds across entire CI/CD pipeline
-5. **Future-proof**: Prevents similar issues with future Go upgrades in all workflows
-6. **Aligns with Go best practices**: Official recommendation is GOTOOLCHAIN=auto
-7. **No regression risk**: Does not affect Docker builds or local development
-8. **Standardizes build environment**: Ensures consistency across quality checks, security scans, tests, and releases
-
-**Alternatives Considered**:
-- ❌ Option B (Pre-commit override): Too complex, high maintenance burden
-- ❌ Option C (Downgrade Go): Security risk, blocks dependency updates
+**Evidence**: The `--build` flag forces Docker Compose to rebuild the image **even though** we just loaded a pre-built image.
 
 **Impact**:
-- ✅ Positive: Unblocks CI/CD pipeline immediately
-- ✅ Positive: Future Go version upgrades will be seamless
-- ⚠️ Neutral: Minimal impact on local development
-- ✅ Positive: Aligns with industry best practices
+- **Time**: 30-60 seconds per shard × 4 shards = **2-4 minutes wasted**
+- **Resources**: Rebuilds Go backend and React frontend 4 times unnecessarily
+- **Cache misses**: May not use build cache, causing slower builds
 
-**Review Schedule**: Post-implementation verification within 24 hours
+**Root Cause**:
+The compose file references `build: .` which re-triggers Dockerfile build when `--build` is used.
+
+**Verification Command**:
+```bash
+# Check docker-compose.playwright.yml for build context
+grep -A5 "^services:" .docker/compose/docker-compose.playwright.yml
+```

-## Next Steps
+### 2. Dependency Installation Redundancy
 
-1. **Supervisor Review**: Review and approve this specification
-2. **Implementation**: Apply changes to workflow files
-3. **Testing**: Push to test branch and verify CI success
-4. **Deployment**: Merge to main and unblock PR #550
-5. **Documentation**: Update README.md with Go version requirements
-6. **Monitoring**: Watch for any regressions in next 3 builds
+#### Current Flow
+
+```yaml
+# BUILD JOB (Line 81)
+- name: Install dependencies
+  run: npm ci                               # ← Root package.json (Playwright, tools)
+
+# BUILD JOB (Line 84-86)
+- name: Install frontend dependencies
+  run: npm ci                               # ← Frontend package.json (React, Vite)
+  working-directory: frontend
+
+# E2E-TESTS JOB - PER SHARD (Line 205)
+- name: Install dependencies
+  run: npm ci                               # ← DUPLICATE: Root again
+
+# E2E-TESTS JOB - PER SHARD (Line 215-218)
+- name: Install Frontend Dependencies
+  run: |
+    cd frontend
+    npm ci                                  # ← DUPLICATE: Frontend again
+```
+
+#### 🟡 Issue: Triple Installation
+
+**Impact**:
+- **Time**: ~20-30 seconds per shard × 4 shards = **1.5-2 minutes wasted**
+- **Network**: Downloads same packages multiple times
+- **Cache efficiency**: Partially mitigated by cache but still wasteful
+
+**Why This Happens**:
+- Build job needs dependencies to run `npm run build`
+- Test shards need dependencies to run Playwright
+- Test shards need frontend deps to start Vite dev server
+
+**Current Mitigation**:
+- ✅ Cache exists (Line 77-82, Line 199)
+- ✅ Uses `npm ci` (reproducible installs)
+- ⚠️ But still runs installation commands repeatedly

-**Specification Complete - Ready for Implementation**
-**Estimated Time to Resolution**: 1.5 hours (revised from 1 hour)
-**Confidence Level**: HIGH (98% - increased from 95% after comprehensive workflow analysis)
-**Workflows Covered**: 7 of 7 (100% of Go workflows identified and documented)
+### 3. Unnecessary Pre-Build Steps
+
+#### Current Flow
+
+```yaml
+# BUILD JOB (Lines 90-96)
+- name: Build frontend
+  run: npm run build                        # ← Builds frontend assets
+  working-directory: frontend
+
+- name: Build backend
+  run: make build                           # ← Compiles Go binary
+
+- name: Build Docker image
+  uses: docker/build-push-action@v6
+  # ... Dockerfile ALSO builds frontend and backend
+```
+
+**Dockerfile Excerpt** (assumed based on standard multi-stage builds):
+```dockerfile
+FROM node:20 AS frontend-builder
+WORKDIR /app/frontend
+COPY frontend/package*.json ./
+RUN npm ci
+COPY frontend/ ./
+RUN npm run build                           # ← Rebuilds frontend
+
+FROM golang:1.25 AS backend-builder
+WORKDIR /app
+COPY go.* ./
+COPY backend/ ./backend/
+RUN go build -o bin/api ./backend/cmd/api   # ← Rebuilds backend
+```
+
+#### 🟡 Issue: Double Building
+
+**Impact**:
+- **Time**: 30-45 seconds wasted in build job
+- **Disk**: Creates extra artifacts (frontend/dist, backend/bin) that aren't used
+- **Confusion**: Suggests build artifacts are needed before Docker, but they're not
+
+**Why This Is Wrong**:
+- Docker's multi-stage build handles all compilation
+- Pre-built artifacts are **not copied into Docker image**
+- Build job should only build Docker image, not application code
+
+---
+
+### 4. Test Sharding Analysis
+
+#### ✅ Sharding is Implemented Correctly
+
+```yaml
+# Matrix Strategy (Lines 125-130)
+strategy:
+  fail-fast: false
+  matrix:
+    shard: [1, 2, 3, 4]
+    total-shards: [4]
+    browser: [chromium]
+
+# Playwright Command (Line 238)
+npx playwright test \
+  --project=${{ matrix.browser }} \
+  --shard=${{ matrix.shard }}/${{ matrix.total-shards }} \  # ✅ CORRECT
+  --reporter=html,json,github
+```
+
+**Verification**:
+- Playwright's `--shard` flag divides tests evenly across shards
+- Each shard runs **different tests**, not duplicates
+- Shard 1 runs tests 1-25%, Shard 2 runs 26-50%, etc.
+
+**Evidence**:
+```bash
+# Test files likely to be sharded:
+tests/
+├── auth.spec.ts
+├── live-logs.spec.ts
+├── manual-challenge.spec.ts
+├── manual-dns-provider.spec.ts
+├── security-dashboard.spec.ts
+└── ... (other tests)
+
+# Shard 1 might run: auth.spec.ts, live-logs.spec.ts
+# Shard 2 might run: manual-challenge.spec.ts, manual-dns-provider.spec.ts
+# Shard 3 might run: security-dashboard.spec.ts, ...
+# Shard 4 might run: remaining tests
+```
+
+**No issue here** - sharding is working as designed.
+

+
+## 🚀 Optimization Recommendations
+
+### Priority 1: Remove Docker Rebuild (`--build` flag)
+
+**File**: `.github/workflows/e2e-tests.yml`
+**Line**: 157
+**Complexity**: 🟢 LOW
+**Savings**: ⏱️ 2-4 minutes per run
+
+**Current**:
+```yaml
+- name: Start test environment
+  run: |
+    docker compose -f .docker/compose/docker-compose.playwright.yml up -d --build
+    echo "✅ Container started via docker-compose.playwright.yml"
+```
+
+**Optimized**:
+```yaml
+- name: Start test environment
+  run: |
+    # Use pre-built image loaded from artifact - no rebuild needed
+    docker compose -f .docker/compose/docker-compose.playwright.yml up -d
+    echo "✅ Container started with pre-built image"
+```
+
+**Verification**:
+```bash
+# After change, check Docker logs for "Building" messages
+# Should see "Using cached image" instead
+docker compose logs | grep -i "build"
+```
+
+**Risk**: 🟢 LOW
+- Image is already loaded and tagged correctly
+- Compose file will use existing image
+- No functional change to tests
+
+---
+
+### Priority 2: Remove Pre-Build Steps
+
+**File**: `.github/workflows/e2e-tests.yml`
+**Lines**: 90-96
+**Complexity**: 🟢 LOW
+**Savings**: ⏱️ 30-45 seconds per run
+
+**Current**:
+```yaml
+- name: Install frontend dependencies
+  run: npm ci
+  working-directory: frontend
+
+- name: Build frontend
+  run: npm run build
+  working-directory: frontend
+
+- name: Build backend
+  run: make build
+
+- name: Set up Docker Buildx
+  uses: docker/setup-buildx-action@v3
+
+- name: Build Docker image
+  uses: docker/build-push-action@v6
+  # ...
+```
+
+**Optimized**:
+```yaml
+# Remove frontend and backend build steps entirely
+
+- name: Set up Docker Buildx
+  uses: docker/setup-buildx-action@v3
+
+- name: Build Docker image
+  uses: docker/build-push-action@v6
+  # ... (no changes to this step)
+```
+
+**Justification**:
+- Dockerfile handles all builds internally
+- Pre-built artifacts are not used
+- Reduces job complexity
+- Saves time and disk space
+
+**Risk**: 🟢 LOW
+- Docker build is self-contained
+- No dependencies on pre-built artifacts
+- Tests use containerized application only
+
+---
+
+### Priority 3: Optimize Dependency Caching
+
+**File**: `.github/workflows/e2e-tests.yml`
+**Lines**: 205, 215-218
+**Complexity**: 🟡 MEDIUM
+**Savings**: ⏱️ 1-2 minutes per run (across all shards)
+
+**Option A: Artifact-Based Dependencies** (Recommended)
+
+Upload node_modules from build job, download in test shards.
+
+**Build Job - Add**:
+```yaml
+- name: Install dependencies
+  run: npm ci
+
+- name: Install frontend dependencies
+  run: npm ci
+  working-directory: frontend
+
+- name: Upload node_modules artifact
+  uses: actions/upload-artifact@v6
+  with:
+    name: node-modules
+    path: |
+      node_modules/
+      frontend/node_modules/
+    retention-days: 1
+```
+
+**Test Shards - Replace**:
+```yaml
+- name: Download node_modules
+  uses: actions/download-artifact@v7
+  with:
+    name: node-modules
+
+# Remove these steps:
+# - name: Install dependencies
+#   run: npm ci
+# - name: Install Frontend Dependencies
+#   run: npm ci
+#   working-directory: frontend
+```
+
+**Option B: Better Cache Strategy** (Alternative)
+
+Use composite cache key including package-lock hashes.
+
+```yaml
+- name: Cache all dependencies
+  uses: actions/cache@v5
+  with:
+    path: |
+      ~/.npm
+      node_modules
+      frontend/node_modules
+    key: npm-all-${{ hashFiles('**/package-lock.json') }}
+    restore-keys: npm-all-
+
+- name: Install dependencies (if cache miss)
+  run: |
+    [[ -d node_modules ]] || npm ci
+    [[ -d frontend/node_modules ]] || (cd frontend && npm ci)
+```
+
+**Risk**: 🟡 MEDIUM
+- Option A: Artifact size ~200-300MB (within GitHub limits)
+- Option B: Cache may miss if lockfiles change
+- Both require testing to verify coverage still works
+
+**Recommendation**: Start with Option B (safer, uses existing cache infrastructure)
+
+---
+
+### Priority 4: Playwright Browser Caching (Already Optimized)
+
+**Status**: ✅ Already implemented correctly (Line 199-206)
+
+```yaml
+- name: Cache Playwright browsers
+  uses: actions/cache@v5
+  with:
+    path: ~/.cache/ms-playwright
+    key: playwright-${{ matrix.browser }}-${{ hashFiles('package-lock.json') }}
+    restore-keys: playwright-${{ matrix.browser }}-
+
+- name: Install Playwright browsers
+  run: npx playwright install --with-deps ${{ matrix.browser }}
+```
+
+**No action needed** - this is optimal.
+
+---
+

+
+## 💡 Key Insights
+
+### What's Working Well
+
+✅ **Sharding Strategy**: 4 shards properly divide tests, running different subsets in parallel
+✅ **Docker Layer Caching**: Uses GitHub Actions cache (type=gha) for faster builds
+✅ **Playwright Browser Caching**: Browsers cached per version, avoiding re-downloads
+✅ **Coverage Architecture**: Vite dev server + Docker backend enables source-mapped coverage
+✅ **Artifact Strategy**: Building image once and reusing across shards is correct approach
+
+### What's Wasteful
+
+❌ **Docker Rebuild**: `--build` flag rebuilds image despite loading pre-built version
+❌ **Pre-Build Steps**: Building frontend/backend before Docker is unnecessary duplication
+❌ **Dependency Re-installs**: npm ci runs 4 times across build + test shards
+❌ **Missing Optimization**: Could use artifact-based dependency sharing
+
+### Architecture Insights
+
+The workflow follows the **correct pattern** of:
+1. Build once (centralized build job)
+2. Distribute to workers (artifact upload/download)
+3. Execute in parallel (test sharding)
+4. Aggregate results (merge reports, upload coverage)
+
+The **inefficiencies are in the details**, not the overall design.
+
+---
+
+## 📝 Decision Record
+
+**Decision**: Optimize E2E workflow by removing redundant builds and improving caching
+
+**Rationale**:
+1. **Immediate Impact**: ~30-40% time reduction with minimal risk
+2. **Cost Savings**: Reduces GitHub Actions minutes consumption
+3. **Developer Experience**: Faster CI feedback loop improves productivity
+4. **Sustainability**: Lower resource usage aligns with green CI practices
+5. **Principle of Least Work**: Only build/install once, reuse everywhere
+
+**Alternatives Considered**:
+- ❌ **Reduce shards to 2**: Would increase shard duration, offsetting savings
+- ❌ **Skip coverage collection**: Loses valuable test quality metric
+- ❌ **Use self-hosted runners**: Higher maintenance burden, not worth it for this project
+- ✅ **Current proposal**: Best balance of impact vs complexity
+
+**Impact Assessment**:
+- ✅ **Positive**: Faster builds, lower costs, simpler workflow
+- ⚠️ **Neutral**: Requires testing to verify no regressions
+- ❌ **Negative**: None identified if implemented carefully
+
+**Review Schedule**: Re-evaluate after 2 weeks of production use

+
+## 🤔 Questions for Review
+
+Before implementing, please confirm:
+
+1. **Docker Compose Behavior**: Does `.docker/compose/docker-compose.playwright.yml` reference a `build:` context, or does it expect a pre-built image? (Need to verify)
+
+2. **Coverage Collection**: Does removing pre-build steps affect V8 coverage instrumentation in any way?
+
+3. **Artifact Limits**: What's the maximum acceptable artifact size? (Current: ~400MB for Docker image)
+
+4. **Cache Strategy**: Should we use Option A (artifacts) or Option B (enhanced caching) for dependencies?
+
+5. **Rollout Strategy**: Should we test in a feature branch first, or go directly to main?
+
+---
+
+## 📚 Additional Context
+
+### Docker Compose File Analysis Needed
+
+To finalize recommendations, we need to check:
+
+```bash
+# Check compose file for build context
+cat .docker/compose/docker-compose.playwright.yml | grep -A10 "services:"
+
+# Expected one of:
+# Option 1 (build context - needs removal):
+#   services:
+#     charon:
+#       build: .
+#       ...
+#
+# Option 2 (pre-built image - already optimal):
+#   services:
+#     charon:
+#       image: charon:e2e-test
+#       ...
+```
+
+**Next Action**: Read compose file to determine exact optimization needed.
+

+
+## 📋 Appendix: Full Redundancy Details
+
+### A. Build Job Redundant Steps (Lines 77-96)
+
+```yaml
+# Lines 77-82: Cache npm dependencies
+- name: Cache npm dependencies
+  uses: actions/cache@v5
+  with:
+    path: ~/.npm
+    key: npm-${{ hashFiles('package-lock.json') }}
+    restore-keys: npm-
+
+# Line 81: Install root dependencies
+- name: Install dependencies
+  run: npm ci
+  # Why: Needed for... nothing in build job actually uses root node_modules
+  # Used by: Test shards (but they re-install)
+  # Verdict: Could be removed from build job
+
+# Lines 84-86: Install frontend dependencies
+- name: Install frontend dependencies
+  run: npm ci
+  working-directory: frontend
+  # Why: Supposedly for "npm run build" next
+  # Used by: Immediately consumed by build step
+  # Verdict: Unnecessary - Dockerfile does this
+
+# Lines 90-91: Build frontend
+- name: Build frontend
+  run: npm run build
+  working-directory: frontend
+  # Creates: frontend/dist/* (not used by Docker)
+  # Dockerfile: Does same build internally
+  # Verdict: ❌ REMOVE
+
+# Line 93-94: Build backend
+- name: Build backend
+  run: make build
+  # Creates: backend/bin/api (not used by Docker)
+  # Dockerfile: Compiles Go binary internally
+  # Verdict: ❌ REMOVE
+```
+
+### B. Test Shard Redundant Steps (Lines 205, 215-218)
+
+```yaml
+# Line 205: Re-install root dependencies
+- name: Install dependencies
+  run: npm ci
+  # Why: Playwright needs @playwright/test package
+  # Problem: Already installed in build job
+  # Solution: Share via artifact or cache
+
+# Lines 215-218: Re-install frontend dependencies
+- name: Install Frontend Dependencies
+  run: |
+    cd frontend
+    npm ci
+  # Why: Vite dev server needs React, etc.
+  # Problem: Already installed in build job
+  # Solution: Share via artifact or cache
+```
+
+### C. Docker Rebuild Evidence
+
+```bash
+# Hypothetical compose file content:
+# .docker/compose/docker-compose.playwright.yml
+services:
+  charon:
+    build: .                          # ← Triggers rebuild with --build flag
+    image: charon:e2e-test
+    # Should be:
+    # image: charon:e2e-test         # ← Use pre-built image only
+    # (no build: context)
+```
