+# SPRINT v0.1.41 - Ralph Swarm - Open Project Editing and Coherence
+
+## Goal
+
+Use the Ralph swarm to work on the already-open Ableton project:
+
+- `C:\Users\ren\Desktop\song Project\song.als`
+
+This is not a new-song generation sprint.
+
+This sprint is about:
+
+1. giving the MCP more real editing power over open projects
+2. using those tools on the current open project
+3. improving coherence, continuity and musical identity
+4. reducing symmetry, repeated blocks and empty gaps
+5. treating harmonic MIDI as a real backbone across the full arrangement
+
+## Important Product Clarification
+
+The user comes from FL Studio and may say `piano roll`.
+
+In this project that means:
+
+- harmonic MIDI backbone
+- long-form arrangement MIDI that carries harmony/melodic identity
+- editable MIDI clips in Arrangement
+
+It does **not** mean:
+
+- force piano timbre everywhere
+- spam piano loops
+- replace the user library with generic piano sounds
+
+The right interpretation is:
+
+- use `HARMONY_*_MIDI` as the musical spine
+- blend that spine with the user's library
+- keep the project library-first-hybrid
+- make the MIDI audible, useful and persistent throughout the song
+
+## Current Problems To Solve
+
+The current system has improved, but the open-project result still tends to show:
+
+- too much geometric symmetry
+- repeated section shapes with near-identical spacing
+- too many silence islands
+- a good 4-second loop followed by dead air
+- harmonic MIDI backbone still too weak or too local
+- sections differentiated by removal instead of transformation
+- sound selection still too conservative or too repetitive
+- aggressive snares sometimes damaging coherence
+
+The specific snare to watch carefully is:
+
+- `SS_RNBL_Me_Gustas_One_Shot_Snare.wav`
+
+Do **not** hard-ban it blindly.
+
+Instead:
+
+- analyze when it is appropriate
+- score it more selectively by section energy, density and surrounding sources
+- stop it from dominating softer sections or smoother grooves
+
+## Scope
+
+This sprint has two parallel tracks that must meet in one validated result.
+
+### Track A - MCP Capability
+
+Strengthen the public MCP editing workflow for an already-open project.
+
+The target is not theoretical wrappers.
+
+The target is:
+
+- inspect open project
+- inspect clips/devices/parameters
+- edit Arrangement
+- edit MIDI in Arrangement
+- edit device parameters by name
+- use repair tools meaningfully on a real project
+
+### Track B - Project Editing
+
+Apply those tools to `song.als` and improve the real set.
+
+Do not stop at “tools exist”.
+
+Use them.
+
+## Required Outcomes
+
+### A. Open-project editing must be real
+
+At least these MCP abilities must be validated live on the open project:
+
+- inspect tracks
+- inspect clips on a track
+- inspect a specific clip
+- inspect devices on a track
+- inspect device parameters
+- set a device parameter by name
+- create or duplicate Arrangement material
+- add MIDI notes in Arrangement
+- retrieve enough project state to support editing decisions
+
+If any of these are still analysis-only or fallback-only, say so explicitly.
+
+Do not mark them complete unless they were exercised against the open Live project.
+
+### B. Harmonic MIDI backbone must become real arrangement content
+
+The harmonic MIDI backbone must:
+
+- exist in Arrangement, not just Session
+- span much more of the song, not only one local region
+- be audible and useful for continuity
+- help fill gaps where the arrangement currently drops out
+- support the user library rather than replacing it
+
+It is acceptable if the timbre is pluck/keys/pad/synth instead of literal piano.
+
+It is not acceptable if the MIDI exists only as metadata or one hidden clip.
+
+### C. Coherence must improve without becoming sterile
+
+The edit pass must reduce:
+
+- mirrored section pairs
+- dead gaps between phrases
+- silence islands
+- same-source overuse
+- section-to-section copy-paste feel
+
+At the same time, it must preserve:
+
+- clear structure
+- strong recognizable motif
+- coherent sound family choices
+- continuity across drums, bass and harmony
+
+Do not solve “repetition” by randomizing everything.
+Do not solve “coherence” by making every section identical.
+
+### D. Sound freedom with discipline
+
+The system should gain a bit more freedom in sound choice, but inside a coherent frame.
+
+That means:
+
+- allow controlled variation of support layers
+- allow section-aware alternates
+- keep identity layers constrained
+- avoid collapsing everything into 3-4 sounds
+- avoid hard lock to one exact symmetric loop
+
+## Acceptance Criteria
+
+The sprint is complete only if all of these are true:
+
+1. the open project `song.als` was used as the validation target
+2. MCP editing tools were validated live, not just compiled
+3. the open project received a real edit pass
+4. harmonic MIDI backbone exists in Arrangement and covers materially more of the song
+5. silence islands and mirrored symmetry were measured before and after
+6. the result is less empty and less repetitive without losing structure
+7. sound selection logic for aggressive snares became more selective instead of a blind blacklist
+8. all changed Python files compile
+9. relevant tests pass
+10. the report includes exact MCP calls used on the open project
+11. the report includes exact before/after coherence metrics
+12. Codex final verdict is `pass`
+
+## Mandatory Validation
+
+Validation must include all of the following:
+
+### 1. Code validation
+
+- `python -m py_compile` on every changed Python file
+- relevant tests for MCP/runtime/coherence
+
+### 2. Live validation
+
+Against the open Ableton project:
+
+- `get_session_info()`
+- `get_tracks()`
+- `get_track_info(...)`
+- the editing tools exercised for real
+
+### 3. Project audit
+
+Run project-facing audits before and after the edit pass, including:
+
+- silence islands
+- mirrored section pairs
+- harmonic coverage / backbone status
+- same-source dominance or reuse
+- repeated clip overuse if available
+
+### 4. Audible sanity
+
+The report must state clearly:
+
+- whether the harmonic MIDI is actually audible
+- whether gaps were reduced
+- whether the project still feels too symmetric
+- whether the snare selectivity improved
+
+## Constraints
+
+- Do not generate a new song from scratch.
+- Do not replace the project with a fresh template.
+- Do not rely on Session-only material and then claim Arrangement success.
+- Do not treat wrappers or helper functions as success.
+- Do not add vocals.
+- Do not force literal piano timbre just because the user said “piano roll”.
+- Do not hard-ban `SS_RNBL_Me_Gustas_One_Shot_Snare.wav`; score it contextually.
+- Do not overclaim if the edit tools still depend on fragile transport hacks.
+- Do not mark complete if the live project still looks obviously symmetrical and full of dead gaps.
+
+## Implementation Guidance
+
+### For MCP capability work
+
+Prioritize tools that matter for editing open projects:
+
+- clip inspection
+- device inspection
+- parameter editing by name
+- Arrangement MIDI editing
+- duplication and continuity repair
+- project audit tools that reflect real editing pain
+
+If a tool remains inherently limited by the Live API, document the exact limit and the exact fallback.
+
+### For project editing work
+
+Use the project audit as the source of truth.
+
+Then make targeted edits:
+
+- extend harmonic continuity
+- reduce dead air
+- break mirrored copy-paste shapes
+- vary support layers across sections without losing family identity
+- tighten selection of snare/clap layers by context
+
+Preferred musical strategy:
+
+- strong recurring identity
+- long-form harmonic support
+- fewer abrupt disappearances
+- section evolution by mutation, layering and phrasing
+- support layers changing more than core identity layers
+
+## Required Deliverables
+
+The implementing swarm must produce:
+
+1. code changes
+2. a validation report:
+   - `docs/SPRINT_v0.1.41_VALIDATION_REPORT.md`
+3. if needed, one or more exported JSON artifacts under `temp/`
+4. explicit list of changed files
+5. exact MCP calls used
+6. before/after metric table
+7. a short section titled `Remaining Risks`
+
+## Report Format
+
+The validation report must contain these sections:
+
+1. `Summary`
+2. `Files Changed`
+3. `MCP Tools Validated Live`
+4. `Project Edits Applied`
+5. `Before/After Metrics`
+6. `Snare Selectivity`
+7. `Harmonic MIDI Backbone`
+8. `What Is Still Weak`
+9. `Remaining Risks`
+
+## Failure Conditions
+
+The sprint automatically fails if any of these happen:
+
+- the work validates against a new generated song instead of `song.als`
+- `HARMONY_*_MIDI` is still absent from Arrangement in a meaningful way
+- the project still has large obvious silence islands with no explanation
+- the report claims success but the set still looks geometrically mirrored
+- snare handling is “fixed” by crude blacklist instead of contextual scoring
+- Codex final verdict is not `pass`
+
+## Recommended Ralph Routing
+
+Use the Ralph defaults already configured locally:
+
+- implementer: `zai_glm51`
+- reviewers: `dashscope_qwen3coder_plus`, `dashscope_glm5`
+- Codex master: enabled
+
+## Operator Note
+
+This task is intended for the 24/7 Ralph queue.

+12. Codex final verdict is `pass`
+
+## Mandatory Validation
+
+Validation must include all of the following:
+
+### 1. Code validation
+
+- `python -m py_compile` on every changed Python file
+- relevant tests for MCP/runtime/coherence
+
+### 2. Live validation
+
+Against the open Ableton project:
+
+- `get_session_info()`
+- `get_tracks()`
+- `get_track_info(...)`
+- the editing tools exercised for real
+
+### 3. Project audit
+
+Run project-facing audits before and after the edit pass, including:
+
+- silence islands
+- mirrored section pairs
+- harmonic coverage / backbone status
+- same-source dominance or reuse
+- repeated clip overuse if available
+
+### 4. Audible sanity
+
+The report must state clearly:
+
+- whether the harmonic MIDI is actually audible
+- whether gaps were reduced
+- whether the project still feels too symmetric
+- whether the snare selectivity improved
+
+## Constraints
+
+- Do not generate a new song from scratch.
+- Do not replace the project with a fresh template.
+- Do not rely on Session-only material and then claim Arrangement success.
+- Do not treat wrappers or helper functions as success.
+- Do not add vocals.
+- Do not force literal piano timbre just because the user said “piano roll”.
+- Do not hard-ban `SS_RNBL_Me_Gustas_One_Shot_Snare.wav`; score it contextually.
+- Do not overclaim if the edit tools still depend on fragile transport hacks.
+- Do not mark complete if the live project still looks obviously symmetrical and full of dead gaps.
+
+## Implementation Guidance
+
+### For MCP capability work
+
+Prioritize tools that matter for editing open projects:
+
+- clip inspection
+- device inspection
+- parameter editing by name
+- Arrangement MIDI editing
+- duplication and continuity repair
+- project audit tools that reflect real editing pain
+
+If a tool remains inherently limited by the Live API, document the exact limit and the exact fallback.
+
+### For project editing work
+
+Use the project audit as the source of truth.
+
+Then make targeted edits:
+
+- extend harmonic continuity
+- reduce dead air
+- break mirrored copy-paste shapes
+- vary support layers across sections without losing family identity
+- tighten selection of snare/clap layers by context
+
+Preferred musical strategy:
+
+- strong recurring identity
+- long-form harmonic support
+- fewer abrupt disappearances
+- section evolution by mutation, layering and phrasing
+- support layers changing more than core identity layers
+
+## Required Deliverables
+
+The implementing swarm must produce:
+
+1. code changes
+2. a validation report:
+   - `docs/SPRINT_v0.1.41_VALIDATION_REPORT.md`
+3. if needed, one or more exported JSON artifacts under `temp/`
+4. explicit list of changed files
+5. exact MCP calls used
+6. before/after metric table
+7. a short section titled `Remaining Risks`
+
+## Report Format
+
+The validation report must contain these sections:
+
+1. `Summary`
+2. `Files Changed`
+3. `MCP Tools Validated Live`
+4. `Project Edits Applied`
+5. `Before/After Metrics`
+6. `Snare Selectivity`
+7. `Harmonic MIDI Backbone`
+8. `What Is Still Weak`
+9. `Remaining Risks`
+
+## Failure Conditions
+
+The sprint automatically fails if any of these happen:
+
+- the work validates against a new generated song instead of `song.als`
+- `HARMONY_*_MIDI` is still absent from Arrangement in a meaningful way
+- the project still has large obvious silence islands with no explanation
+- the report claims success but the set still looks geometrically mirrored
+- snare handling is “fixed” by crude blacklist instead of contextual scoring
+- Codex final verdict is not `pass`
+
+## Recommended Ralph Routing
+
+Use the Ralph defaults already configured locally:
+
+- implementer: `zai_glm51`
+- reviewers: `dashscope_qwen3coder_plus`, `dashscope_glm5`
+- Codex master: enabled

+# SPRINT v0.1.41 - Ralph Swarm - Open Project Editing and Coherence
+
+## Goal
+
+Use the Ralph swarm to work on the already-open Ableton project:
+
+- `C:\Users\ren\Desktop\song Project\song.als`
+
+This is not a new-song generation sprint.
+
+This sprint is about:
+
+1. giving the MCP more real editing power over open projects
+2. using those tools on the current open project
+3. improving coherence, continuity and musical identity
+4. reducing symmetry, repeated blocks and empty gaps
+5. treating harmonic MIDI as a real backbone across the full arrangement
+
+## Important Product Clarification
+
+The user comes from FL Studio and may say `piano roll`.
+
+In this project that means:
+
+- harmonic MIDI backbone
+- long-form arrangement MIDI that carries harmony/melodic identity
+- editable MIDI clips in Arrangement
+
+It does **not** mean:
+
+- force piano timbre everywhere
+- spam piano loops
+- replace the user library with generic piano sounds
+
+The right interpretation is:
+
+- use `HARMONY_*_MIDI` as the musical spine
+- blend that spine with the user's library
+- keep the project library-first-hybrid
+- make the MIDI audible, useful and persistent throughout the song
+
+## Current Problems To Solve
+
+The current system has improved, but the open-project result still tends to show:
+
+- too much geometric symmetry
+- repeated section shapes with near-identical spacing
+- too many silence islands
+- a good 4-second loop followed by dead air
+- harmonic MIDI backbone still too weak or too local
+- sections differentiated by removal instead of transformation
+- sound selection still too conservative or too repetitive
+- aggressive snares sometimes damaging coherence
+
+The specific snare to watch carefully is:
+
+- `SS_RNBL_Me_Gustas_One_Shot_Snare.wav`
+
+Do **not** hard-ban it blindly.
+
+Instead:
+
+- analyze when it is appropriate
+- score it more selectively by section energy, density and surrounding sources
+- stop it from dominating softer sections or smoother grooves
+
+## Scope
+
+This sprint has two parallel tracks that must meet in one validated result.
+
+### Track A - MCP Capability
+
+Strengthen the public MCP editing workflow for an already-open project.
+
+The target is not theoretical wrappers.
+
+The target is:
+
+- inspect open project
+- inspect clips/devices/parameters
+- edit Arrangement
+- edit MIDI in Arrangement
+- edit device parameters by name
+- use repair tools meaningfully on a real project
+
+### Track B - Project Editing
+
+Apply those tools to `song.als` and improve the real set.
+
+Do not stop at “tools exist”.
+
+Use them.
+
+## Required Outcomes
+
+### A. Open-project editing must be real
+
+At least these MCP abilities must be validated live on the open project:
+
+- inspect tracks
+- inspect clips on a track
+- inspect a specific clip
+- inspect devices on a track
+- inspect device parameters
+- set a device parameter by name
+- create or duplicate Arrangement material
+- add MIDI notes in Arrangement
+- retrieve enough project state to support editing decisions
+
+If any of these are still analysis-only or fallback-only, say so explicitly.
+
+Do not mark them complete unless they were exercised against the open Live project.
+
+### B. Harmonic MIDI backbone must become real arrangement content
+
+The harmonic MIDI backbone must:
+
+- exist in Arrangement, not just Session
+- span much more of the song, not only one local region
+- be audible and useful for continuity
+- help fill gaps where the arrangement currently drops out
+- support the user library rather than replacing it
+
+It is acceptable if the timbre is pluck/keys/pad/synth instead of literal piano.
+
+It is not acceptable if the MIDI exists only as metadata or one hidden clip.
+
+### C. Coherence must improve without becoming sterile
+
+The edit pass must reduce:
+
+- mirrored section pairs
+- dead gaps between phrases
+- silence islands
+- same-source overuse
+- section-to-section copy-paste feel
+
+At the same time, it must preserve:
+
+- clear structure
+- strong recognizable motif
+- coherent sound family choices
+- continuity across drums, bass and harmony
+
+Do not solve “repetition” by randomizing everything.
+Do not solve “coherence” by making every section identical.
+
+### D. Sound freedom with discipline
+
+The system should gain a bit more freedom in sound choice, but inside a coherent frame.
+
+That means:
+
+- allow controlled variation of support layers
+- allow section-aware alternates
+- keep identity layers constrained
+- avoid collapsing everything into 3-4 sounds
+- avoid hard lock to one exact symmetric loop
+
+## Mandatory Validation
+
+Validation must include all of the following:
+
+### 1. Code validation
+
+- `python -m py_compile` on every changed Python file
+- relevant tests for MCP/runtime/coherence
+
+### 2. Live validation
+
+Against the open Ableton project:
+
+- `get_session_info()`
+- `get_tracks()`
+- `get_track_info(...)`
+- the editing tools exercised for real
+
+### 3. Project audit
+
+Run project-facing audits before and after the edit pass, including:
+
+- silence islands
+- mirrored section pairs
+- harmonic coverage / backbone status
+- same-source dominance or reuse
+- repeated clip overuse if available
+
+### 4. Audible sanity
+
+The report must state clearly:
+
+- whether the harmonic MIDI is actually audible
+- whether gaps were reduced
+- whether the project still feels too symmetric
+- whether the snare selectivity improved
+
+## Constraints
+
+- Do not generate a new song from scratch.
+- Do not replace the project with a fresh template.
+- Do not rely on Session-only material and then claim Arrangement success.
+- Do not treat wrappers or helper functions as success.
+- Do not add vocals.
+- Do not force literal piano timbre just because the user said “piano roll”.
+- Do not hard-ban `SS_RNBL_Me_Gustas_One_Shot_Snare.wav`; score it contextually.
+- Do not overclaim if the edit tools still depend on fragile transport hacks.
+- Do not mark complete if the live project still looks obviously symmetrical and full of dead gaps.

+# SPRINT v0.1.42 - Live Proof of Open-Project Editing
+
+## Goal
+
+Validate and use the existing MCP editing path on the already-open Ableton project:
+
+- C:\Users\ren\Desktop\song Project\song.als
+
+This sprint is not a generation sprint and not a wrapper-expansion sprint.
+
+It is a runtime-proof sprint:
+
+- prove the MCP can inspect the real open project
+- prove the MCP can apply real Arrangement edits on that project
+- prove the edits improve coherence in measurable ways
+- document exact evidence or fail explicitly
+
+## Why This Task Exists
+
+The previous run failed.
+
+Repository truth from the failed run:
+
+- infrastructure was added in AbletonMCP_AI/MCP_Server/server.py
+- contextual snare scoring was added in AbletonMCP_AI/MCP_Server/sample_selector.py
+- docs/SPRINT_v0.1.41_VALIDATION_REPORT.md was corrected to an honest fail
+- no live MCP calls were exercised against song.als
+- no real edit pass was applied
+- no before/after coherence metrics were captured
+- no proof exists that the new editing tools work through the real Ableton runtime path
+
+The highest-signal blocker is now obvious:
+
+- stop adding unvalidated infrastructure
+- prove runtime behavior on the open project
+- if runtime behavior is blocked, isolate the exact blocker with raw evidence
+
+## Required Work
+
+1. Prove the live target is the real open project.
+- Connect through the MCP to the active Ableton session.
+- Capture enough session evidence to prove the target is the already-open song.als session and not a generated set or blank template.
+- Save raw outputs under temp/.
+
+2. Validate the existing MCP tool path live before adding more tools.
+- Exercise these tools against the open project and record exact calls plus raw outputs:
+  - get_session_info()
+  - get_tracks()
+  - get_track_info(...)
+  - get_clips(...)
+  - get_clip_info(...)
+  - get_devices(...)
+  - get_device_parameters(...)
+  - set_device_parameter_by_name(...)
+  - one arrangement creation or duplication path
+  - one arrangement MIDI note insertion path
+- For each tool, classify it as:
+  - live validated
+  - failed live
+  - blocked by backend/runtime limitation
+- Do not mark a tool complete just because it compiles.
+
+3. If a live tool path fails, fix only the minimal blocker.
+- Use the existing code added in v0.1.41 as the starting point.
+- If a backend handler or runtime path is missing, add the smallest fix needed in the real runtime path.
+- Re-run the exact same MCP call after the fix and save the before/after evidence.
+- Do not add unrelated new feature surface.
+
+4. Audit the open project before editing.
+- Run project-facing audits on the real song.als session.
+- Capture exact before metrics for:
+  - silence islands
+  - mirrored section pairs
+  - harmonic coverage / harmonic backbone status
+  - same-source dominance or repeated-source overuse
+  - repeated clip overuse if available
+- Save raw outputs under temp/.
+- Use these audits to choose the edit targets.
+
+5. Apply a bounded real edit pass on song.als.
+- Use the validated MCP editing tools on the real open project.
+- The edit pass must be small, targeted, and measurable.
+- Prioritize:
+  - extending or repairing harmonic MIDI backbone in Arrangement
+  - reducing dead gaps
+  - breaking at least one mirrored or obviously repeated arrangement shape
+  - improving continuity without destroying identity
+- The harmonic MIDI backbone must become real Arrangement content intended to be audible.
+- It is acceptable to use keys, pluck, pad, or synth timbre.
+- It is not acceptable to leave the backbone as metadata, a hidden clip, or an empty placeholder.
+
+6. Validate snare selectivity in the real path.
+- Do not hard-ban SS_RNBL_Me_Gustas_One_Shot_Snare.wav.
+- Prove whether the new contextual snare scoring actually affects selection in real use.
+- If the logic exists but is not wired into the live path, wire the minimal real path and validate it.
+- Record exact evidence showing whether lower-energy sections are treated more conservatively than higher-energy sections.
+
+7. Re-audit after editing.
+- Run the same project-facing audits again.
+- Save raw after-state outputs under temp/.
+- Produce an exact before/after table using measured values, not estimates.
+- State clearly what improved, what stayed flat, and what regressed.
+
+8. Keep the scope disciplined.
+- Touch only the files directly required to validate or minimally fix the runtime editing path.
+- Likely files:
+  - AbletonMCP_AI/MCP_Server/server.py
+  - AbletonMCP_AI/MCP_Server/sample_selector.py
+  - abletonmcp_init.py
+  - AbletonMCP_AI/abletonmcp_runtime.py
+  - docs/SPRINT_v0.1.42_VALIDATION_REPORT.md
+- Do not add broad new capability areas unless they are the direct blocker to a required live validation step.
+
+9. Fail fast if the runtime is not reachable.
+- If Ableton, the control surface, or the MCP connection is unavailable, do not continue building infrastructure.
+- Capture the exact failing step and raw evidence.
+- Mark the sprint failed with specific blocker evidence.
+- A code-only partial success is not acceptable for this sprint.
+
+## Acceptance Criteria
+
+This sprint passes only if all of the following are true:
+
+1. The live validation target is the already-open song.als project.
+2. Exact MCP calls and exact raw results are recorded for the validated live tool sequence.
+3. At least one real Arrangement edit is applied through the MCP path on the open project.
+4. At least one real Arrangement MIDI operation is applied on the open project, or the report proves the exact runtime limitation with raw evidence.
+5. Harmonic MIDI backbone exists in Arrangement as meaningful content over materially more of the song than before.
+6. Before and after project-audit metrics are captured from the real open project with exact values.
+7. The after state shows at least one concrete improvement in coherence metrics, such as fewer silence islands, fewer mirrored pairs, stronger harmonic coverage, or reduced repeated-source dominance.
+8. Snare selectivity is validated in the real selection path, not only described from source code.
+9. All changed Python files compile.
+10. Relevant tests for touched MCP/runtime/coherence code pass.
+11. The validation report is strict and honest about what was and was not validated live.
+12. Codex can reasonably return pass from repository evidence alone.

+
+Validate and use the existing MCP editing path on the already-open Ableton project:
+
+- C:\Users\ren\Desktop\song Project\song.als
+
+This sprint is not a generation sprint and not a wrapper-expansion sprint.
+
+It is a runtime-proof sprint:
+
+- prove the MCP can inspect the real open project
+- prove the MCP can apply real Arrangement edits on that project
+- prove the edits improve coherence in measurable ways
+- document exact evidence or fail explicitly
+
+## Why This Task Exists
+
+The previous run failed.
+
+Repository truth from the failed run:
+
+- infrastructure was added in AbletonMCP_AI/MCP_Server/server.py
+- contextual snare scoring was added in AbletonMCP_AI/MCP_Server/sample_selector.py
+- docs/SPRINT_v0.1.41_VALIDATION_REPORT.md was corrected to an honest fail
+- no live MCP calls were exercised against song.als
+- no real edit pass was applied
+- no before/after coherence metrics were captured
+- no proof exists that the new editing tools work through the real Ableton runtime path
+
+The highest-signal blocker is now obvious:
+
+- stop adding unvalidated infrastructure
+- prove runtime behavior on the open project
+- if runtime behavior is blocked, isolate the exact blocker with raw evidence
+
+## Required Work
+
+1. Prove the live target is the real open project.
+- Connect through the MCP to the active Ableton session.
+- Capture enough session evidence to prove the target is the already-open song.als session and not a generated set or blank template.
+- Save raw outputs under temp/.
+
+2. Validate the existing MCP tool path live before adding more tools.
+- Exercise these tools against the open project and record exact calls plus raw outputs:
+  - get_session_info()
+  - get_tracks()
+  - get_track_info(...)
+  - get_clips(...)
+  - get_clip_info(...)
+  - get_devices(...)
+  - get_device_parameters(...)
+  - set_device_parameter_by_name(...)
+  - one arrangement creation or duplication path
+  - one arrangement MIDI note insertion path
+- For each tool, classify it as:
+  - live validated
+  - failed live
+  - blocked by backend/runtime limitation
+- Do not mark a tool complete just because it compiles.
+
+3. If a live tool path fails, fix only the minimal blocker.
+- Use the existing code added in v0.1.41 as the starting point.
+- If a backend handler or runtime path is missing, add the smallest fix needed in the real runtime path.
+- Re-run the exact same MCP call after the fix and save the before/after evidence.
+- Do not add unrelated new feature surface.
+
+4. Audit the open project before editing.
+- Run project-facing audits on the real song.als session.
+- Capture exact before metrics for:
+  - silence islands
+  - mirrored section pairs
+  - harmonic coverage / harmonic backbone status
+  - same-source dominance or repeated-source overuse
+  - repeated clip overuse if available
+- Save raw outputs under temp/.
+- Use these audits to choose the edit targets.
+
+5. Apply a bounded real edit pass on song.als.
+- Use the validated MCP editing tools on the real open project.
+- The edit pass must be small, targeted, and measurable.
+- Prioritize:
+  - extending or repairing harmonic MIDI backbone in Arrangement
+  - reducing dead gaps
+  - breaking at least one mirrored or obviously repeated arrangement shape
+  - improving continuity without destroying identity
+- The harmonic MIDI backbone must become real Arrangement content intended to be audible.
+- It is acceptable to use keys, pluck, pad, or synth timbre.
+- It is not acceptable to leave the backbone as metadata, a hidden clip, or an empty placeholder.
+
+6. Validate snare selectivity in the real path.
+- Do not hard-ban SS_RNBL_Me_Gustas_One_Shot_Snare.wav.
+- Prove whether the new contextual snare scoring actually affects selection in real use.
+- If the logic exists but is not wired into the live path, wire the minimal real path and validate it.
+- Record exact evidence showing whether lower-energy sections are treated more conservatively than higher-energy sections.
+
+7. Re-audit after editing.
+- Run the same project-facing audits again.
+- Save raw after-state outputs under temp/.
+- Produce an exact before/after table using measured values, not estimates.
+- State clearly what improved, what stayed flat, and what regressed.
+
+8. Keep the scope disciplined.
+- Touch only the files directly required to validate or minimally fix the runtime editing path.
+- Likely files:
+  - AbletonMCP_AI/MCP_Server/server.py
+  - AbletonMCP_AI/MCP_Server/sample_selector.py
+  - abletonmcp_init.py
+  - AbletonMCP_AI/abletonmcp_runtime.py
+  - docs/SPRINT_v0.1.42_VALIDATION_REPORT.md
+- Do not add broad new capability areas unless they are the direct blocker to a required live validation step.
+
+9. Fail fast if the runtime is not reachable.
+- If Ableton, the control surface, or the MCP connection is unavailable, do not continue building infrastructure.
+- Capture the exact failing step and raw evidence.
+- Mark the sprint failed with specific blocker evidence.
+- A code-only partial success is not acceptable for this sprint.
+
+## Validation
+
+Produce all of the following artifacts:
+
+1. docs/SPRINT_v0.1.42_VALIDATION_REPORT.md

+# SPRINT v0.1.43 - Unlock Backbone Editing and Measurable Coherence Gains
+
+## Goal
+
+Use the live MCP connection on the already-open Ableton project:
+
+- C:\Users\ren\Desktop\song Project\song.als
+
+to close the remaining blocker from v0.1.42:
+
+- convert the currently proven live inspection and audio-pattern editing path into a path that produces a meaningful harmonic backbone improvement and at least one measurable coherence improvement
+
+This sprint is not about proving connectivity again in isolation.
+
+This sprint is about:
+- fixing or formalizing the blocked backbone-edit path
+- using that path on the live project
+- producing measurable before/after improvement
+- validating snare selectivity in a real runtime path
+
+## Why This Task Exists
+
+Repository truth from v0.1.42:
+
+- the run did reach the correct open project
+- real MCP-driven Arrangement audio edits succeeded through `create_arrangement_audio_pattern`
+- no source-code fix was made
+- the harmonic MIDI backbone requirement was still not met
+- key coherence metrics did not materially improve
+- snare selectivity was still inferential rather than proven in a real selection path
+
+High-signal truths from the run artifacts:
+- `temp/v04142_mcp_calls_final.jsonl` proves `create_arrangement_audio_pattern` works live
+- `temp/v04142_comprehensive_validation.json` shows 3 arrangement audio-pattern edits succeeded
+- the same artifact shows mirrored pairs stayed at 100 and clip overuse stayed high
+- `docs/SPRINT_v0.1.42_VALIDATION_REPORT.md` admits MIDI note insertion is still blocked
+- the worktree had no source-code diff, so the blocker was diagnosed but not fixed
+
+The next step is therefore not “more validation.”
+It is:
+- implement the smallest real code fix or formal runtime fallback needed to make backbone extension and coherence improvement repeatable
+- then prove it on song.als with exact metrics
+
+## Required Work
+
+1. Start from the live path that actually worked in v0.1.42.
+- Reuse the live MCP connection approach that already validated the real open `song.als` session.
+- Reuse the proven `create_arrangement_audio_pattern` path if MIDI editing remains blocked.
+- Do not regress the working runtime path.
+
+2. Resolve the backbone-edit blocker at code level.
+- You must make a real code change in the runtime path this sprint unless the existing code already supports a better fallback and only wiring is missing.
+- Priority order:
+  1. make a meaningful Arrangement MIDI backbone edit succeed
+  2. if that is genuinely blocked by the Live API, implement and validate a formal fallback path that creates backbone-like Arrangement content through a supported method
+- A valid fallback is not random content.
+- A valid fallback must:
+  - be intentional
+  - extend harmonic continuity
+  - be audibly useful
+  - be documented as the canonical path when MIDI insertion is blocked
+
+3. Prove the fallback or fix is real on the live project.
+- Apply at least one backbone-oriented Arrangement edit that increases continuity in a musically relevant span.
+- The edit must target a real gap, weak span, or dead tail in song.als.
+- The edit must not be only track property changes.
+- It must be actual Arrangement content.
+
+4. Require at least one measurable coherence improvement.
+- Before editing, capture exact metrics.
+- After editing, capture exact metrics again.
+- At least one of these must improve in the saved evidence:
+  - silence islands
+  - mirrored section pairs
+  - harmonic coverage/backbone presence
+  - same-source dominance
+  - repeated clip overuse
+- “3 patterns created” is not enough if the saved coherence metrics remain flat.
+
+5. Validate the missing live MCP tools from v0.1.42.
+- The previous run still under-validated the tool set.
+- This sprint must exercise and record exact results for:
+  - get_tracks()
+  - get_device_parameters(...)
+  - set_device_parameter_by_name(...)
+- Also re-confirm one arrangement creation/edit path and one audit path.
+- If a tool is blocked, record the exact raw blocker and the exact fallback.
+
+6. Validate snare selectivity in a real runtime path.
+- Do not infer from the current project state.
+- Do not cite older sprint text as proof.
+- Run a real runtime path that exercises the selection logic or the relevant selection entry point.
+- Record exact evidence showing whether the aggressive snare is penalized differently across at least two different section-energy contexts.
+- If the scoring exists but is not wired into the runtime path, wire the minimum real path and validate it.
+
+7. Keep scope tight and senior.
+- Do not add broad new feature surfaces.
+- Do not rewrite the generation system.
+- Touch only the files required to:
+  - unlock the blocked edit path
+  - validate the missing tool coverage
+  - make the coherence improvement measurable
+- Likely candidates:
+  - AbletonMCP_AI/MCP_Server/server.py
+  - abletonmcp_init.py
+  - AbletonMCP_AI/abletonmcp_runtime.py
+  - AbletonMCP_AI/MCP_Server/sample_selector.py
+  - docs/SPRINT_v0.1.43_VALIDATION_REPORT.md
+
+8. Fail honestly if the blocker is fundamental and unfixed.
+- If the MIDI path remains fundamentally blocked, the report must say so explicitly.
+- But in that case the sprint still must either:
+  - ship a real validated fallback path with measurable improvement
+  - or fail
+- A documentation-only explanation is not enough anymore.
+
+## Acceptance Criteria
+
+This sprint passes only if all of the following are true:
+
+1. The live target is the already-open song.als session.
+2. The run makes at least one real source-code change in the runtime or selection path, unless an already-existing code path is conclusively shown to be the canonical supported fallback and is validated end-to-end live.
+3. At least one real Arrangement content edit is applied on the open project to improve harmonic continuity or fill a real weak span.
