+## Phase 80 — Compact Creation and Optional Track Inspector
+
+### Goal
+Replace the large creation sidebar with a sequencer Create dropdown. Keep all creation actions and shortcuts, and provide an optional track inspector to reclaim horizontal editing space.
+
+### Tasks and acceptance criteria
+- [x] Implement the described workflow with validated errors and safe ownership.
+- [x] Pass relevant core and/or GUI tests.
+- [x] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Implemented: sequencer Create menu retains empty/audio/MIDI track creation, WAV import, instrument loading and MIDI editing. The inspector is hidden by default and available under View/Track inspector, reclaiming 204 pixels. Core baseline and full Xvfb GUI suite passed, including menu callbacks, creation/undo, layout sizes and floating panels. Inspector visibility is session-local.

+
+## Phase 81 — Persistent Track Insert Chains
+
+### Goal
+Add a bounded C99 per-track insert model with validation, clone/history/duplicate support and backward-compatible project persistence. Loading metadata must not load plugin binaries.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 82 — Prepared Track Insert Processing
+
+### Goal
+Compile track inserts into serial modular graphs before track gain/pan. Cover audio and MIDI rendering, export, bypass, cleanup and callback safety; explicitly reject unsupported routing.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 83 — Track Inserts in the Modular Workspace
+
+### Goal
+Offer a selected-track insert view alongside the global graph, with clear signal order and transactional Add effect actions.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 84 — Searchable Effect Discovery
+
+### Goal
+Make LADSPA, VST2, VST3 and CLAP effects easy to find and add, including Linux VST3 bundles, format filters and clear compatibility errors.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 85 — Insert Chain Editing
+
+### Goal
+Expose move up/down, remove and bypass with one undo step per action and safe prepared-plan adoption.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 86 — Insert Inspection and Controls
+
+### Goal
+Show selected effect identity and supported generic controls. Provide reset where supported and clearly identify unavailable native editors/parameters.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 87 — Reusable Effect Chain Presets
+
+### Goal
+Save and load portable chain metadata with bounded validation, transactional replacement and explicit missing-plugin errors at preparation.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 88 — Parallel Insert Mix and Chain Output
+
+### Goal
+Expose per-slot wet/dry and chain output gain with finite bounded values and render tests for endpoints and ordering.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.
+
+---
+
+## Phase 89 — Host VST3 Gallery and Integrated Qualification
+
+### Goal
+Load compatible installed host VST3 effects in real track chains, capture screenshots, update usage documentation and qualify integration, persistence and real-time boundaries.
+
+### Tasks and acceptance criteria
+- [ ] Implement the described workflow with validated errors and safe ownership.
+- [ ] Pass relevant core and/or GUI tests.
+- [ ] Document behavior and limitations; commit this phase separately.
+
+### Implementation status
+Planned.

 ## Recommended Execution Order
 
 Reorder the phases when the audit reveals a blocking dependency. Do not mark a phase complete merely because code exists: its acceptance criteria must be demonstrated by builds, tests, or documented manual verification.
