-
-## Phase 24: Fix Recording Crash
-
-**Goal:** Fix C++ client crash when Start Recording is clicked
-
-**Plans:** 1 plan
-
-Plans:
-- [x] 24-01-PLAN.md — Fix method names and parameters in useRecordingHelpers.js and JKSessionScreen.js
-
-**Requirements:**
-- CRASH-01: Call RegisterRecordingCallbacks before recording operations (ALREADY DONE in JKSessionScreen.js line 500)
-- CRASH-02: Use correct method name StartRecording (not StartMediaRecording)
-- CRASH-03: Use correct method name StopRecording (not FrontStopRecording)
-- CRASH-04: Pass individual parameters to StartRecording (not settings object)
-
-**Success Criteria:**
-1. RegisterRecordingCallbacks is called during session or recording modal initialization
-2. StartRecording method name matches legacy implementation
-3. StopRecording method name matches legacy implementation
-4. Parameters to StartRecording match legacy signature (id, tracks, video, chat, framerate)
-
-**Dependencies:** None
-
-**Key Files:**
-- `jam-ui/src/hooks/useRecordingHelpers.js`
-- `jam-ui/src/components/client/JKSessionScreen.js`
-- `jam-ui/src/components/client/JKSessionRecordingModal.js`
-
----
-
-## Phase 25: Memory Leak Audit
-
-**Goal:** Audit and fix memory leaks in recording modal
-
-**Plans:** 1 plan
-
-Plans:
-- [x] 25-01-PLAN.md — Fix timer, callback, and async cleanup in recording components
-
-**Requirements:**
-- MEM-01: Audit recording modal useEffect cleanup functions
-- MEM-02: Audit timer/interval cleanup during recording lifecycle
-- MEM-03: Verify no memory growth while recording modal is open
-
-**Success Criteria:**
-1. All useEffect hooks in recording modal have proper cleanup functions
-2. All timers/intervals are cleared on unmount or state change
-3. Recording modal can remain open 15+ minutes without memory growth
-
-**Dependencies:** Phase 24 (crash must be fixed first)
-
-**Key Files:**
-- `jam-ui/src/components/client/JKSessionRecordingModal.js`
-- `jam-ui/src/hooks/useRecordingHelpers.js`
-
----
-
-## Research Reference
-
-See: `.planning/research/RECORDING-ANALYSIS.md`
-
-Key findings:
-- `RegisterRecordingCallbacks` is ALREADY called in JKSessionScreen.js line 500 (not a gap)
-- Wrong method names in jam-ui vs legacy (`StartMediaRecording` vs `StartRecording`)
-- Wrong method names (`FrontStopRecording` vs `StopRecording`)
-- Parameter format mismatch (object vs unpacked params)

+**Note:** CTRL requirements were not explicitly mapped to phases but start/stop verified working by user during Phase 24 testing.
+
+### Memory Leak Audit
+
+- [x] **MEM-01**: Audit recording modal useEffect cleanup functions ✓
+- [x] **MEM-02**: Audit timer/interval cleanup during recording lifecycle ✓
+- [x] **MEM-03**: Verify no memory growth while recording modal is open ✓
+
+## Future Requirements
+
+Deferred to future milestones.
+
+### Recording Management
+
+- **RMGT-01**: Track selection - Choose which tracks to include in recording
+- **RMGT-02**: Recording playback - Play back recordings within the modal
+- **RMGT-03**: Recording management - Save, delete, rename recordings
+
+## Out of Scope
+
+Explicitly excluded for this milestone.
+
+| Feature | Reason |
+|---------|--------|
+| Track selection | Keep v1.5 focused on crash fix and basic controls |
+| Recording playback | Not blocking core recording functionality |
+| Recording management | Defer to future milestone |
+| Backend changes | Frontend-only fixes |
+| Metronome | Separate feature |
+
+## Traceability
+
+Which phases cover which requirements.
+
+| Requirement | Phase | Status |
+|-------------|-------|--------|
+| CRASH-01 | Phase 24 | Complete |
+| CRASH-02 | Phase 24 | Complete (moot - research incorrect) |
+| CRASH-03 | Phase 24 | Complete (moot - research incorrect) |
+| CRASH-04 | Phase 24 | Complete (moot - research incorrect) |
+| CTRL-01 | — | Complete (implicit, user verified) |
+| CTRL-02 | — | Complete (implicit, user verified) |
+| CTRL-03 | — | Not tested |
+| MEM-01 | Phase 25 | Complete |
+| MEM-02 | Phase 25 | Complete |
+| MEM-03 | Phase 25 | Complete |
+
+**Coverage:**
+- v1.5 requirements: 10 total
+- Complete: 9
+- Not tested: 1 (CTRL-03 pause)
+

+
+## Milestone Summary
+
+**Shipped:** 9 of 10 v1.5 requirements
+**Adjusted:** CRASH-02/03/04 research was incorrect, actual fix was JSON parsing
+**Not tested:** CTRL-03 (pause recording)

+# Milestone v1.5: Fix Session Recording
+
+**Status:** ✅ SHIPPED 2026-02-25
+**Phases:** 24-25
+**Total Plans:** 2
+
+## Overview
+
+Fixed session recording crash and memory leaks to enable stable, long-duration recording sessions.
+
+## Phases
+
+### Phase 24: Fix Recording Crash
+
+**Goal**: Fix C++ client crash when Start Recording is clicked
+**Depends on**: None
+**Plans**: 1 plan
+
+Plans:
+- [x] 24-01: Fix method names and parameters in useRecordingHelpers.js and JKSessionScreen.js
+
+**Details:**
+
+Requirements:
+- CRASH-01: Call RegisterRecordingCallbacks before recording operations (ALREADY DONE in JKSessionScreen.js line 500)
+- CRASH-02: Use correct method name StartRecording (not StartMediaRecording)
+- CRASH-03: Use correct method name StopRecording (not FrontStopRecording)
+- CRASH-04: Pass individual parameters to StartRecording (not settings object)
+
+Success Criteria:
+1. RegisterRecordingCallbacks is called during session or recording modal initialization
+2. StartRecording method name matches legacy implementation
+3. StopRecording method name matches legacy implementation
+4. Parameters to StartRecording match legacy signature (id, tracks, video, chat, framerate)
+
+Key Files:
+- `jam-ui/src/hooks/useRecordingHelpers.js`
+- `jam-ui/src/components/client/JKSessionScreen.js`
+- `jam-ui/src/components/client/JKSessionRecordingModal.js`
+
+**Note:** Original research was incorrect. Actual fix was JSON parsing in rest.js (recording.id undefined). Method name changes (CRASH-02/03/04) were applied then reverted as StartMediaRecording is the correct method.
+
+---
+
+### Phase 25: Memory Leak Audit
+
+**Goal**: Audit and fix memory leaks in recording modal
+**Depends on**: Phase 24 (crash must be fixed first)
+**Plans**: 1 plan
+
+Plans:
+- [x] 25-01: Fix timer, callback, and async cleanup in recording components
+
+**Details:**
+
+Requirements:
+- MEM-01: Audit recording modal useEffect cleanup functions
+- MEM-02: Audit timer/interval cleanup during recording lifecycle
+- MEM-03: Verify no memory growth while recording modal is open
+
+Success Criteria:
+1. All useEffect hooks in recording modal have proper cleanup functions
+2. All timers/intervals are cleared on unmount or state change
+3. Recording modal can remain open 15+ minutes without memory growth
+
+Key Files:
+- `jam-ui/src/components/client/JKSessionRecordingModal.js`
+- `jam-ui/src/hooks/useRecordingHelpers.js`
+
+---
+
+## Milestone Summary
+
+**Key Decisions:**
+- Conditional cleanup for window.JK callbacks (multiple hook instances share globals)
+- Ignore flag pattern for async operations in useEffect
+- Unpack recordSettings to individual params for C++ client compatibility
+
+**Issues Resolved:**
+- C++ client crash on Start Recording (JSON parsing fix)
+- Memory leaks in recording modal (timer, callback, async cleanup)
+- "State update on unmounted component" warnings eliminated
+
+**Issues Deferred:**
+- CTRL-01/02/03 basic controls requirements (not explicitly mapped to phases)
+- Duplicate recording start paths (doStartRecording vs useRecordingHelpers)
+- Documentation inconsistency in 24-VERIFICATION.md
+
+**Technical Debt Incurred:**
+- 24-VERIFICATION.md describes reverted code
+- Traceability table references non-existent Phase 26
