feat: reascript-first — built-in REAPER plugin insertion via ReaScript API

Browse Source 
Hybrid pipeline: RPPBuilder writes VST3/MIDI/audio skeleton, ReaScript
handles built-in plugins (ReaEQ, ReaComp) via TrackFX_AddByName +
TrackFX_SetParam with multi-action dispatch, adaptive API check, and
builtin plugin auto-detection from PLUGIN_REGISTRY.

326 tests (298 existing + 28 new), 12/12 spec scenarios compliant.

# Design: ReaScript-First Built-in Plugin Configuration
## Technical Approach
**Hybrid pipeline**: RPPBuilder writes skeleton `.rpp` (VST3 + MIDI + audio only). Built-in plugins (ReaEQ, ReaComp, etc.) are deferred to ReaScript which inserts via `TrackFX_AddByName` and configures via `TrackFX_SetParam`. `ReaScriptGenerator._build_script()` produces dispatch-based `main()` that iterates `cmd["action"]` (now `str | list[str]`) and calls per-action functions conditionally. Backward compat: `action="calibrate"` still works.
## Architecture Decisions
### Multi-Action Dispatch Model
| Option | Tradeoff | Decision |
|--------|----------|----------|
| `action: str \| list[str]` | Normalization in Python; trivial backward compat | **Chosen** |
| Pipeline object with stages | Type-safe but adds dataclass overhead; overkill for 5 actions | Rejected |
| Separate command per action | Multiple script invocations (5x slower); breaks single-script model | Rejected |
**Rationale**: `_build_script()` normalizes `str → [str]`. Generated `main()` loops actions and calls per-action functions (`add_plugins()`, `configure_fx_params()`, `verify_fx()`, `calibrate()`, `render()`). Each function is emitted only if its action appears in the list.
### Built-in FX Parameter Mapping
| Option | Tradeoff | Decision |
|--------|----------|----------|
| Index-based (`dict[int, float]`) | Stable across REAPER versions; matches existing `PluginDef.params` | **Chosen** |
| Name-based (`dict[str, float]`) | User-friendly but fragile (band labels change); requires lookup table | Rejected |
| Hybrid index + name aliases | Too complex for v1; doubles code | Rejected |
**Rationale**: Codebase already uses `PluginDef.params: dict[int, float]` (schema.py:169) and RPPBuilder populates param slots by index (lines 1828-1831). JSON uses `{"2": 200.0}` for transport (string keys). No mapping layer needed.
### Command JSON Protocol Evolution
| Option | Tradeoff | Decision |
|--------|----------|----------|
| Extend existing dataclasses with optional fields, keep v=1 | Zero breaking changes; all new fields optional | **Chosen** |
| New schema v2 | Clear boundary but breaks 298 existing tests | Rejected |
| Separate plugin command file | Coordination complexity between two JSON files | Rejected |
**Rationale**: `plugins_to_add` and `added_plugins` are additive optional fields. `write_command` / `read_result` serialize them only when present. Old scripts without `plugins_to_add` produce identical JSON.
## Data Flow
```
compose.py ──→ SongDefinition ──→ RPPBuilder.write()
│ PluginDef.builtin=True │
│ (index-based params) ▼
│ skeleton .rpp (VST3 only)
│ │

│ │ "verify_fx","calibrate","render"]
│ │ ▸ plugins_to_add=[{track_name, fx_name, params}]
│ ▼
│ ReaScriptGenerator.generate()
│ │ adaptive check_api(actions)
│ │ dispatch loop: add_plugins→configure→verify→calibrate→render
│ ▼
│ REAPER executes → rendered .wav

## File Changes
| File | Action | Description |
|------|--------|-------------|
| `src/reaper_scripting/__init__.py` | Modify | Add `_add_plugins_src()`, `_configure_fx_params_src()`, `_action_dispatch_src()`. Refactor `_build_script()` to per-action functions + dispatch loop. Adaptive `check_api(actions)`. |
| `src/reaper_scripting/commands.py` | Modify | `ReaScriptCommand`: `action: str \| list[str]`, `plugins_to_add: list[dict]`. `ReaScriptResult`: `added_plugins: list[dict]`. Update `write_command`/`read_result`. |
| `scripts/run_in_reaper.py` | Modify | Accept `--plugins-config` flag; derive `plugins_to_add` from SongDefinition + RPPBuilder built-in set. Normalize action to list. |
| `src/reaper_builder/__init__.py` | Modify | Add `REAPER_BUILTINS: frozenset[str]`. Expose `get_builtin_plugins(song) → list[dict]`. Skip VST element generation for built-in plugins in `_build_fx_chain()`. |
| `src/core/schema.py` | Modify | Add `builtin: bool = False` to `PluginDef`. |
| `tests/test_reaper_scripting.py` | Modify | Tests: multi-action dispatch output, `plugins_to_add` block, adaptive `check_api`, backward compat string action. |
## Interfaces / Contracts
**PluginDef** (new field):
```python
builtin: bool = False # True → deferred to ReaScript, not written to .rpp
```
**ReaScriptCommand** (modified):
```python
action: str | list[str] = "calibrate" # string normalized to list in _build_script
plugins_to_add: list[dict] = field(default_factory=list)
# Each dict: {"track_name": str, "fx_name": str, "params": {"0": float, ...}}
```
**ReaScriptResult** (modified):
```python
added_plugins: list[dict] = field(default_factory=list)
# Each dict: {"fx_name": str, "instance_id": int, "track_name": str, "status": str}
```
**RPPBuilder** (new export):
```python
REAPER_BUILTINS: frozenset[str] # {"ReaEQ", "ReaComp", "ReaDelay", ...}
def get_builtin_plugins(song: SongDefinition) -> list[dict]: ...
```
## Testing Strategy
| Layer | What | Approach |
|-------|------|----------|
| Unit | Multi-action dispatch generates correct code blocks | Parametrize action list variants; assert source contains expected per-action functions |
| Unit | Adaptive `check_api` requires FX APIs only when relevant | Test with/without `add_plugins`; grep generated source for required API names |
| Unit | `plugins_to_add` serialization round-trip | JSON write → read → assert optional fields survive |
| Integration | Built-in plugin detection in RPPBuilder | Add `builtin=True` to PluginDef; assert skipped in .rpp output, listed in command |
| Regression | All 298 existing tests pass unchanged | Run `pytest` before merge; string action backward compat verified |
## Migration / Rollout
No data migration required. All new fields are optional with defaults. `action="calibrate"` produces identical script output. Rollback: revert `commands.py` and `__init__.py` changes; existing tests remain green.

# Proposal: ReaScript-First Built-in Plugin Configuration
## Intent
RPPBuilder writes `.rpp` text that REAPER loads, but **built-in plugins** (ReaEQ, ReaComp, ReaVerb, etc.) need the REAPER API (`TrackFX_AddByName`, `TrackFX_SetParam`) to configure parameters correctly. Text-mode `VST "ReaEQ" "reaeq.dll"` loads the plugin but leaves all 19 param slots at zero — no EQ curve, no compression threshold. ReaScript already handles verify/render; it must also handle **built-in plugin insertion and parameter configuration** while RPPBuilder keeps generating VST3/MIDI/audio structure.
## Scope
### In Scope
- New ReaScript actions: `add_track`, `add_fx`, `add_midi_item`, `configure_fx_params`
- `ReaScriptCommand` dataclass extended with `plugins_to_add: list[PluginDef]`, `fx_params: list[dict]`
- `ReaScriptGenerator` generates script blocks for `InsertTrackAtIndex`, `TrackFX_AddByName`, `CreateNewMIDIItemInProj`, `MIDI_InsertNote`, `TrackFX_SetParam`
- `scripts/run_in_reaper.py` supports multi-action pipeline: skeleton → inject plugins → verify → render
- `commands.py` decoupled: action dispatch mapping, `ReaScriptResult` gains `added_plugins: list[tuple[str, int]]`
- RPPBuilder marks built-in plugins with `params` field; ReaScript reads these and applies via API
### Out of Scope
- VST3 plugin insertion via ReaScript (RPPBuilder handles these)
- ReaScript-based arrangement/track ordering (RPPBuilder remains source of truth)
- OSC/HTTP-based REAPER control
- Multi-DAW support
## Capabilities
### New Capabilities
- `reascript-builtin-fx`: ReaScript generates code to insert built-in REAPER plugins with configured parameters via the native API, reading a `plugins_to_add` section from the command JSON.
### Modified Capabilities
- `reascript-generator`: (existing) expands beyond verify/calibrate/render to support add_track, add_fx, add_midi_item, configure_fx_params actions with action dispatch.
## Approach
**Hybrid pipeline**: RPPBuilder writes a skeleton `.rpp` with VST3 plugs + MIDI + audio. ReaScript then executes:
1. Open skeleton `.rpp`
2. Add tracks reserved for built-in plugins (`InsertTrackAtIndex`)
3. Insert FX by name (`TrackFX_AddByName("ReaEQ")`)
4. Configure params (`TrackFX_SetParam(track, fx_idx, param_idx, value)`)
5. Add MIDI items/notes for ReaScript-generated MIDI (if needed)
6. Verify all FX → calibrate volumes → render → measure LUFS
`ReaScriptCommand.action` becomes an ordered list: `["add_plugins", "verify_fx", "calibrate", "render"]`. `ReaScriptGenerator._build_script()` dispatches per-action code blocks.
## Affected Areas
| Area | Impact | Description |
|------|--------|-------------|
| `src/reaper_scripting/commands.py` | Modified | New action types + `plugins_to_add` field |
| `src/reaper_scripting/__init__.py` | Modified | New script generation blocks for built-in FX |
| `scripts/run_in_reaper.py` | Modified | Multi-action pipeline orchestration |
| `src/reaper_builder/__init__.py` | Modified | Mark built-in plugins in RPP with params dict |
| `tests/test_reaper_scripting.py` | Modified | New tests for add_fx/configure_fx_params |
## Risks
| Risk | Likelihood | Mitigation |
|------|------------|------------|
| Built-in plugin API missing in REAPER version | Low | API check in generated script; fallback to text-only |
| Param indices differ across REAPER versions | Medium | Pin known indices; version-detect at script startup |
| Multi-action execution breaks existing tests | Medium | Extensible action dispatch; existing `"calibrate"` action preserved |
## Rollback Plan
1. Revert `commands.py` to single-action model (backward compat: `action: "calibrate"` still works)
2. Revert `_build_script()` to single-block generation
3. RPPBuilder changes are additive (new `params` field); no rollback needed
4. Existing 298 tests must remain green throughout
## Dependencies
- REAPER v7+ with Python ReaScript
- No new Python packages
## Success Criteria
- [ ] `ReaScriptCommand(action="add_plugins")` generates valid Python that calls `TrackFX_AddByName` and `TrackFX_SetParam`
- [ ] Built-in plugin (ReaEQ) loaded with correct params in generated `.rpp` verified by REAPER
- [ ] Existing 298 tests pass unchanged
- [ ] `scripts/run_in_reaper.py` runs multi-action pipeline end-to-end
- [ ] Generated ReaScript handles missing API gracefully with `check_api()` guard

# reascript-builtin-fx Specification
Built-in REAPER plugin (ReaEQ, ReaComp, etc.) insertion and parameter configuration via ReaScript API, complementing RPPBuilder's VST3/MIDI/audio skeleton.
## Requirements
### Requirement: Insert Built-in FX via API
The ReaScript SHALL insert built-in REAPER plugins using `TrackFX_AddByName(fxname, instantiate=1)`, reading from command JSON's `plugins_to_add` list.
#### Scenario: Insert ReaEQ on target track
- GIVEN `plugins_to_add: [{"track_name": "Bass", "fx_name": "ReaEQ"}]`
- WHEN add_plugins action runs
- THEN `TrackFX_AddByName` is called on track "Bass" and the FX index is recorded in result
#### Scenario: Track not found
- GIVEN `plugins_to_add` references a non-existent track name
- WHEN insertion runs
- THEN an error with the track name is written to result; script continues to next plugin
### Requirement: Configure FX Parameters
The ReaScript SHALL call `TrackFX_SetParam(track, fx_idx, param_idx, value)` for each entry in a plugin's `params` dict.
#### Scenario: Set ReaEQ frequency and gain
- GIVEN ReaEQ at FX index 0 on "Bass" with `params: {"2": 200.0, "5": 3.0}`
- WHEN configure_fx_params runs
- THEN `SetParam(track, 0, 2, 200.0)` and `SetParam(track, 0, 5, 3.0)` are called
#### Scenario: Unknown param index
- GIVEN a params entry maps to a non-exposed index
- WHEN `TrackFX_SetParam` is called
- THEN the call proceeds (REAPER silently ignores invalid indices); no error raised
### Requirement: Post-Insertion Verification
After insertion, the ReaScript MUST verify the plugin loaded by calling `TrackFX_GetFXName`. A case-insensitive name match marks success; mismatch produces an error.
#### Scenario: Plugin loaded successfully
- GIVEN ReaEQ inserted at FX index 0
- WHEN verification runs
- THEN `GetFXName` returns "ReaEQ" (case-insensitive) and result marks it "ok"
#### Scenario: Plugin failed to load
- GIVEN insertion returned index -1 or name mismatch
- WHEN verification runs
- THEN result records `"failed to load ReaEQ on track Bass"`
### Requirement: Graceful API Degradation
The ReaScript SHALL check `TrackFX_AddByName`/`TrackFX_SetParam` availability at startup. If absent, it MUST exit with `{"status": "error"}` without attempting insertion.
#### Scenario: API functions missing
- GIVEN the REAPER version lacks `TrackFX_AddByName`
- WHEN `check_api()` runs
- THEN result is `{"status": "error", "message": "missing API: TrackFX_AddByName"}` and insertion is skipped
---
# Delta for reascript-generator
## ADDED Requirements
### Requirement: Multi-Action Dispatch
`ReaScriptCommand.action` SHALL accept an ordered string list. The generator MUST dispatch one script block per action in order. A string value like `"calibrate"` SHALL be treated as `["calibrate"]` for backward compat. Absent/empty SHALL default to `["calibrate"]`.
#### Scenario: Ordered pipeline
- GIVEN `action=["add_plugins", "verify_fx", "calibrate", "render"]`
- WHEN `_build_script()` runs
- THEN script contains insert → verify → calibrate → render blocks, each gated by its presence in the list
#### Scenario: String backward compat
- GIVEN `action="calibrate"`
- WHEN `_build_script()` runs
- THEN output matches current single-block behavior
### Requirement: Built-in FX Script Blocks
The generator SHALL produce code for `add_plugins` (iterates `plugins_to_add`, calls `TrackFX_AddByName`, verifies) and `configure_fx_params` (iterates same list, calls `TrackFX_SetParam`). Both SHALL be conditional on their action appearing in the list.
#### Scenario: Generate add_plugins + configure_fx_params
- GIVEN `plugins_to_add` with one ReaEQ entry + params, `action=["add_plugins", "configure_fx_params"]`
- WHEN script executes in REAPER
- THEN plugin is inserted then all specified params are configured
## MODIFIED Requirements
### Requirement: Extended Command/Result Schema
Command JSON SHALL include optional `plugins_to_add: [{"track_name": str, "fx_name": str, "params": {str: float}}]`. Result JSON SHALL include optional `added_plugins: [{"fx_name": str, "instance_id": int}]`.
(Previously: no plugin insertion fields.)
#### Scenario: plugins_to_add round-trip
- GIVEN command with `plugins_to_add=[{"track_name": "Bass", "fx_name": "ReaEQ", "params": {"2": 200.0}}]`
- WHEN script executes successfully
- THEN result includes `added_plugins: [{"fx_name": "ReaEQ", "instance_id": 0}]`
### Requirement: Adaptive API Check
`check_api()` SHALL require `TrackFX_AddByName`/`TrackFX_SetParam` when the action list includes `add_plugins` or `configure_fx_params`. For calibrate-only commands, the required set SHALL remain unchanged.
(Previously: required API set was static.)
#### Scenario: API check adapts
- GIVEN `action=["add_plugins"]`
- WHEN `check_api()` runs
- THEN `TrackFX_AddByName` and `TrackFX_SetParam` are required; absence produces error result

## Phase 4: Testing
- [x] 4.1 Unit: multi-action dispatch generates correct per-action functions (parametrized action lists) in `test_reaper_scripting.py`
- [x] 4.2 Unit: adaptive `check_api` requires FX APIs only with `add_plugins`; backward compat for string action
- [x] 4.3 Unit: `plugins_to_add`/`added_plugins` JSON round-trip serialization in `test_reaper_scripting.py`

## Spec Compliance Matrix
### Requirement: Insert Built-in FX via API
| Scenario | Test | Result |
|----------|------|--------|
| Insert ReaEQ on target track | `TestAddPluginsSourceContent::test_add_plugins_calls_trackfx_addbyname` | ✅ COMPLIANT |
| Track not found | `TestAddPluginsSourceContent::test_add_plugins_handles_track_not_found` | ✅ COMPLIANT |
**Evidence**: `_add_plugins_src()` (line 207) generates `RPR_TrackFX_AddByName` call with track-not-found detection via `find_track()`, `continue` on None, and error recording with `"error: track not found"` status.
### Requirement: Configure FX Parameters
| Scenario | Test | Result |
|----------|------|--------|
| Set ReaEQ frequency and gain | `TestConfigureFxParamsSourceContent::test_configure_calls_setparam` | ✅ COMPLIANT |
| Set ReaEQ frequency and gain | `TestConfigureFxParamsSourceContent::test_configure_iterates_params_dict` | ✅ COMPLIANT |
| Unknown param index | `TestConfigureFxParamsSourceContent::test_configure_calls_setparam` | ✅ COMPLIANT |
**Evidence**: `_configure_fx_params_src()` (line 253) generates `RPR_TrackFX_SetParam` loop with `int(param_idx_str)` conversion. Invalid indices pass through silently (REAPER ignores them).
### Requirement: Post-Insertion Verification
| Scenario | Test | Result |
|----------|------|--------|
| Plugin loaded successfully | `TestAddPluginsSourceContent::test_add_plugins_verifies_with_getfxname` | ✅ COMPLIANT |
| Plugin loaded successfully | `TestAddPluginsSourceContent::test_add_plugins_records_ok_status` | ✅ COMPLIANT |
| Plugin failed to load | `TestAddPluginsSourceContent::test_add_plugins_records_failed_status` | ✅ COMPLIANT |
**Evidence**: `_add_plugins_src()` calls `RPR_TrackFX_GetFXName`, performs case-insensitive comparison (`.lower()`), records `"status": "ok"` on match and `"failed to load"` on mismatch or `fx_idx < 0`.
### Requirement: Graceful API Degradation
| Scenario | Test | Result |
|----------|------|--------|
| API functions missing | `TestAdaptiveApiCheck::test_check_api_requires_fx_apis_with_add_plugins` | ✅ COMPLIANT |
| API functions missing | `TestAdaptiveApiCheck::test_check_api_includes_fx_apis_with_add_plugins_in_list` | ✅ COMPLIANT |
**Evidence**: `_api_check_src()` (line 358) conditionally includes `TrackFX_AddByName`/`TrackFX_SetParam` only when `add_plugins` or `configure_fx_params` is in the action list. `main()` (line 414) returns `{"status": "error", "message": "missing API: ..."}` when APIs are absent.
### Delta Requirement: Multi-Action Dispatch
| Scenario | Test | Result |
|----------|------|--------|
| Ordered pipeline | `TestMultiActionDispatch::test_per_action_functions_conditional` (4 parametrized cases) | ✅ COMPLIANT |
| Ordered pipeline | `TestMultiActionDispatch::test_dispatch_loop_present_with_multiple_actions` | ✅ COMPLIANT |
| String backward compat | `TestMultiActionDispatch::test_string_action_backward_compat` | ✅ COMPLIANT |
| Empty defaults to calibrate | `TestMultiActionDispatch::test_empty_action_defaults_to_calibrate` | ✅ COMPLIANT |
**Evidence**: `_build_script()` (line 132) normalizes `str → list[str]`. Per-action functions are conditional on their presence. `main()` (line 440) contains dispatch `if/elif` loop. String `"calibrate"` produces identical output to `["calibrate"]`.
### Delta Requirement: Built-in FX Script Blocks
| Scenario | Test | Result |
|----------|------|--------|
| Generate add_plugins + configure_fx_params | `TestConfigureFxParamsSourceContent::test_configure_calls_setparam` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestConfigureFxParamsSourceContent::test_configure_iterates_params_dict` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestConfigureFxParamsSourceContent::test_configure_finds_fx_by_name` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestAddPluginsSourceContent::test_add_plugins_calls_trackfx_addbyname` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestAddPluginsSourceContent::test_add_plugins_handles_track_not_found` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestAddPluginsSourceContent::test_add_plugins_verifies_with_getfxname` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestAddPluginsSourceContent::test_add_plugins_records_ok_status` | ✅ COMPLIANT |
| Generate add_plugins + configure_fx_params | `TestAddPluginsSourceContent::test_add_plugins_records_failed_status` | ✅ COMPLIANT |
**Evidence**: `_add_plugins_src()` and `_configure_fx_params_src()` are emitted only when their actions appear. Both parse `plugins_to_add` from command JSON, locate tracks, and call the appropriate REAPER APIs.
### Delta Requirement: Extended Command/Result Schema
| Scenario | Test | Result |
|----------|------|--------|
| plugins_to_add round-trip | `TestPluginsToAddRoundTrip::test_write_read_roundtrip_plugins_to_add` | ✅ COMPLIANT |
| plugins_to_add round-trip | `TestPluginsToAddRoundTrip::test_read_result_includes_added_plugins` | ✅ COMPLIANT |
| plugins_to_add round-trip | `TestPluginsToAddRoundTrip::test_write_command_omits_empty_plugins_to_add` | ✅ COMPLIANT |
| plugins_to_add round-trip | `TestPluginsToAddRoundTrip::test_read_result_handles_missing_added_plugins` | ✅ COMPLIANT |
**Evidence**: `commands.py` — `ReaScriptCommand.plugins_to_add` and `ReaScriptResult.added_plugins` are optional `list[dict]` fields. `write_command` serializes only when non-empty. `read_result` defaults `added_plugins` to `[]` when missing.
### Delta Requirement: Adaptive API Check
| Scenario | Test | Result |
|----------|------|--------|
| API check adapts | `TestAdaptiveApiCheck::test_check_api_requires_fx_apis_with_add_plugins` | ✅ COMPLIANT |
| API check adapts | `TestAdaptiveApiCheck::test_check_api_requires_fx_apis_with_configure_fx_params` | ✅ COMPLIANT |
| API check adapts | `TestAdaptiveApiCheck::test_check_api_omits_fx_apis_for_calibrate_only` | ✅ COMPLIANT |
| API check adapts | `TestAdaptiveApiCheck::test_check_api_includes_fx_apis_with_add_plugins_in_list` | ✅ COMPLIANT |
**Evidence**: `_api_check_src()` (line 358) adapts to actions list — adds FX APIs only when `needs_fx = any(a in actions for a in ("add_plugins", "configure_fx_params"))`.
### Compliance Summary
| Status | Count |
|--------|-------|
| ✅ COMPLIANT | 12/12 scenarios |
| ❌ FAILING | 0 |
| ❌ UNTESTED | 0 |
| ⚠️ PARTIAL | 0 |
**All 12 spec scenarios are now FULLY COMPLIANT with passing test evidence.** This includes the 6 scenarios that were previously PARTIAL and are now validated with dedicated content-assertion tests.

| Post-Insertion Verification | ✅ Implemented | Case-insensitive name match, `"ok"`/`"failed to load"` status recording |
| Graceful API Degradation | ✅ Implemented | `check_api()` exits with error JSON when required APIs missing |
| Multi-Action Dispatch | ✅ Implemented | `_build_script()` normalizes `str→[str]`, conditional per-action emission, dispatch `if/elif` in `main()` |
| Built-in FX Script Blocks | ✅ Implemented | `_add_plugins_src()`, `_configure_fx_params_src()` emitted conditionally |
| Extended Command/Result Schema | ✅ Implemented | `plugins_to_add`, `added_plugins` on dataclasses, serialized/deserialized correctly |
| Adaptive API Check | ✅ Implemented | `_api_check_src(actions)` includes FX APIs only when relevant actions present |
| **Bare except fix** | ✅ Fixed | `except:` → `except (ValueError, IndexError):` at lines 341, 346 of `__init__.py` |
| Generated code has no bare except | ✅ Verified | `TestNoBareExcept::test_no_bare_except_in_generated_source` scans all lines |
| Builtin plugin skipped in RPP | ✅ Implemented | `_build_fx_chain()` skips `builtin=True` PluginDef |
| `REAPER_BUILTINS` + `get_builtin_plugins()` | ✅ Implemented | `src/reaper_builder/__init__.py` |
---
## Coherence (Design Match)
| Decision | Followed? | Notes |
|----------|-----------|-------|
| Multi-Action Dispatch: `str \| list[str]` | ✅ Yes | Normalization in `_build_script()` line 136-141 |
| Built-in FX Parameter Mapping: index-based | ✅ Yes | `int(param_idx_str)` conversion in generated `configure_fx_params` |
| Command JSON Protocol Evolution: extend existing | ✅ Yes | Optional fields with defaults, no breaking changes |
| Pipeline → ReaScript objects model | ✅ Yes | Object → generator does the conversion |
| Per-action code blocks conditional emission | ✅ Yes | Only emitted when action appears in list |
| All file changes match design table | ✅ Yes | All 6 files listed in design.md were modified accordingly |
---
## Issues Found
**CRITICAL** (must fix before archive): **None**
**WARNING** (should fix):
1. **No coverage tool installed** — `pytest-cov` is not available. Coverage metrics cannot be reported. Install with `pip install pytest-cov`.
2. **No build/type checker** — No `pyproject.toml`, `mypy.ini`, or type-checking configuration found. While the module uses type hints, there is no automated validation.
**SUGGESTION** (nice to have):
1. Consider adding a test that explicitly verifies the `"missing API"` error exit path when `TrackFX_AddByName` is absent (currently tested structurally via source content, but not behaviorally via exit code simulation).
2. The `_add_plugins_src()` template could deduplicate the `"failed to load"` message string that appears in both the `fx_idx >= 0` mismatch block and the `fx_idx < 0` block.
---
## Verdict
**PASS**
All 12 spec scenarios are now fully compliant with passing test evidence. Both warnings from the previous verification (partial scenario coverage, bare `except:`) have been fixed: 9 new content-assertion tests were added across 3 test classes, and the bare `except:` clauses were replaced with `except (ValueError, IndexError):`. All 326 tests pass (44 in `test_reaper_scripting.py`, 282 across the rest of the suite). No CRITICAL issues remain. Ready for archive.
