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.

Correctness (Static — Structural Evidence)

Requirement	Status	Notes
Insert Built-in FX via API	✅ Implemented	_add_plugins_src() generates TrackFX_AddByName, find_track, verification via GetFXName
Configure FX Parameters	✅ Implemented	_configure_fx_params_src() generates TrackFX_SetParam loop with string→int key conversion
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.
