Demo videos from PR builds now expire after 90 days and are posted
directly to PR threads. Uses object tagging with S3 lifecycle policies
for automatic cleanup.
## Changes
**Workflow** (`.github/workflows/tests.yml`)
- Replace `hkusu/s3-upload-action@v2` with
`ramonpaolo/action-upload-s3@main` for tagging support
- Tag uploaded objects: `expiration=90days`, `Source=github-actions`,
`Type=pr-demo-video`
- Generate unique filenames: `pr-{number}-{timestamp}.gif`
- Post PR comment with embedded video using `actions/github-script@v7`
**Documentation** (`CI_CD.md`)
- S3 lifecycle policy configuration (filters on `expiration=90days` tag)
- IAM permission requirements: `s3:PutObject`, `s3:PutObjectTagging`
## S3 Lifecycle Setup Required
```json
{
"Rules": [{
"ID": "ExpirePRDemoVideosAfter90Days",
"Status": "Enabled",
"Filter": {"Tag": {"Key": "expiration", "Value": "90days"}},
"Expiration": {"Days": 90}
}]
}
```
Apply with: `aws s3api put-bucket-lifecycle-configuration --bucket
<bucket> --lifecycle-configuration file://policy.json`
## Notes
- gh-pages `video.mp4` unaffected (served from GitHub Pages, not S3)
- Existing S3 objects without tags remain unchanged

Consolidates the browser mode Docker build from 3 stages to 2 by
removing the redundant intermediate `deps` stage and cleaning dev
dependencies in-place after build.
## Changes
- **Stage 1 (builder)**: Install all deps → build → remove dev deps with
`yarn install --production`
- **Stage 2 (production)**: Copy built artifacts and production
node_modules from builder (previously split across builder + deps
stages)
**Before:**
```dockerfile
# Stage 1: Build
RUN yarn install --frozen-lockfile
RUN yarn build:server
# Stage 2: Production dependencies
COPY --from=builder /build/package.json /build/yarn.lock ./
RUN yarn install --production --frozen-lockfile
# Stage 3: Production
COPY --from=builder /build/dist ./dist
COPY --from=deps /deps/node_modules ./node_modules
```
**After:**
```dockerfile
# Stage 1: Build and prepare production dependencies
RUN yarn install --frozen-lockfile
RUN yarn build:server
RUN yarn install --production --frozen-lockfile
# Stage 2: Production
COPY --from=builder /build/dist ./dist
COPY --from=builder /build/node_modules ./node_modules
```
No functional changes to final image; eliminates redundant package
resolution and copying.

Docker build was failing at `yarn install --frozen-lockfile` because
`app/yarn.lock` and `backend/yarn.lock` weren't available during
dependency installation.
## Changes
- Simplified `Dockerfile.browser` to copy all source files and
dependencies at once before running `yarn install`
- This ensures all necessary files including `app/yarn.lock` and
`backend/yarn.lock` are available for reproducible dependency
installation
```dockerfile
# Before
COPY package.json yarn.lock ./
COPY app/package.json ./app/
COPY backend/package.json ./backend/
# Install ALL dependencies (needed for build)
RUN yarn install --frozen-lockfile --network-timeout 100000
# Copy source files
COPY tsconfig.json ./
COPY src ./src
COPY backend ./backend
COPY events ./events
COPY app ./app
# After
COPY package.json yarn.lock ./
COPY tsconfig.json ./
COPY src ./src
COPY backend ./backend
COPY events ./events
COPY app ./app
# Install ALL dependencies (needed for build)
RUN yarn install --frozen-lockfile --network-timeout 100000
```
This approach trades Docker layer caching optimization for a simpler,
more straightforward Dockerfile structure where all files are copied at
once.

The Docker browser build fails because yarn cannot install
`@electron/node-gyp` from GitHub without git.
## Changes
- Add git to builder stage in `Dockerfile.browser`
- Git is excluded from final production image via multi-stage build
## Technical Details
The `yarn.lock` contains a git-based dependency:
```
"@electron/node-gyp@https://github.com/electron/node-gyp#06b29aafb7708acef8b3669835c8a7857ebc92d2"
```
Alpine Linux base image lacks git by default. Installing it only in the
builder stage (where `yarn install` runs) resolves the build failure
without affecting production image size.

Fixes TypeScript compilation errors in UI tests and resolves CI workflow
configuration issue.
## Changes Made
### 1. Fixed expandTopic parameter order in ui-tests.spec.ts
- Corrected 5 function calls from `expandTopic(page, 'path')` to
`expandTopic('path', page)`
- Function signature: `expandTopic(path: string, browser: Page)`
- Aligns with existing usage in all scenario files (showNumericPlot.ts,
publishTopic.ts, etc.)
### 2. Fixed CI workflow configuration
- Updated `.github/workflows/tests.yml` to checkout PR code instead of
base branch
- Added `ref: ${{ github.event.pull_request.head.sha }}` to all 4
checkout actions
- The `pull_request_target` event defaults to checking out the base
branch; this fix ensures CI tests the PR's code
## Root Cause
The CI workflow was testing the base branch (master) which still had the
wrong parameter order, while the PR had the correct fix. This caused CI
to report TypeScript errors even though the PR code was correct.
## Testing
- ✅ TypeScript compilation passes locally (`tsc` and `yarn build`)
- ✅ Parameter order matches function signature and codebase conventions
- ✅ CI workflow now correctly tests PR code
- ✅ All 4 CI jobs (test, ui-tests, demo-video, test-browser) will use
corrected code
