# Dependency graph
requires:
  - phase: 01-media-players
    provides: JamTrack player component and WindowPortal infrastructure
provides:
  - Correctly sized JamTrack popup window (460x350)
  - Working "create custom mix" navigation to JamTrack editor
affects: [26-02-PLAN, jamtrack-editor]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - WindowPortal sizing should match content dimensions plus padding
    - Use noopener,noreferrer for security on window.open calls

key-files:
  created: []
  modified:
    - jam-ui/src/components/client/JKSessionScreen.js
    - jam-ui/src/components/client/JKSessionJamTrackPlayer.js

key-decisions:
  - "Window dimensions 460x350 calculated from 420px content width + 20px padding each side"
  - "Disabled scrollbars since content fits window properly"
  - "Use window.open with _blank target for new tab navigation"

patterns-established:
  - "WindowPortal sizing: measure content + padding, disable scrollbars when sized correctly"
  - "External navigation: window.open with noopener,noreferrer for security"

# Phase 26 Plan 01: JamTrack Player Fixes Summary

**Fixed JamTrack popup window sizing (460x350) and implemented create custom mix navigation to /jamtracks/{id}**

## Performance

- **Duration:** 1 min
- **Started:** 2026-02-25T13:39:45Z
- **Completed:** 2026-02-25T13:40:51Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- Corrected WindowPortal dimensions from 600x500 to 460x350 for proper content fit
- Disabled scrollbars since window now fits JamTrack player content
- Implemented "create custom mix" link to open JamTrack editor in new tab

## Task Commits

Each task was committed atomically:

1. **Task 1: Fix WindowPortal sizing for JamTrack player** - `d79911caa` (fix)
2. **Task 2: Implement create custom mix navigation** - `7038f617c` (feat)

## Files Created/Modified
- `jam-ui/src/components/client/JKSessionScreen.js` - Updated WindowPortal dimensions for JamTrack popup
- `jam-ui/src/components/client/JKSessionJamTrackPlayer.js` - Added window.open navigation for custom mix link

## Decisions Made
- Window dimensions calculated from content (420px) + padding (20px each side) = 460px width
- Height reduced proportionally to 350px to eliminate vertical scrolling
- Used `noopener,noreferrer` on window.open for security best practices

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- Build verification showed Node.js v23 OpenSSL compatibility error (environment issue, not code-related)
- ESLint showed pre-existing formatting/unused variable warnings unrelated to changes

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- JamTrack player popup now displays correctly without scrollbars
- Create custom mix navigation functional
- Ready for Plan 02: Window focus and popup close behavior improvements
