# Perfect Machine Module Library

This is the runtime shelf for coherent parts that deserve to be inside Mimir,
not a trophy wall for abandoned attempts. Each module below has one owner and a
job-interview answer for why it belongs in the body of the machine.

## Runtime Modules

| Module | Owner | Purpose | Code |
| --- | --- | --- | --- |

| Fensalir lowering | `Mimir.Runtime` -> Fensalir | Pure mapping from Mimir rolling/video/audio state into Fensalir GPU sensor, stereo-depth, and acoustic field frames. | `src/Mimir.Runtime/Synchronization/MimirFensalirFieldLowering.cs` |
| Module catalog | `Mimir.Runtime` | Indexes the live module set and verification commands. | `src/Mimir.Runtime/Synchronization/MimirModuleLibrary.cs` |
| Manifest factory | `Mimir.Runtime` | Produces an exportable JSON manifest for tools, docs, UI, and remote witnesses. | `src/Mimir.Runtime/Synchronization/MimirPerfectMachineManifest.cs` |

## Current Authority Map

- `Mimir.Runtime` owns device and synchronization truth before it becomes a
  renderer/DSP packet.
- Fensalir owns GPU resource lifetime, temporal field rendering, debug UI, and
  program video publication.
- Faust owns hot sample movement, alignment, spatialization, separation, and
  stem generation.
- CultMesh carries typed state surfaces; remote nodes may observe and decode,
  but they do not become independent clock authorities.
- OBS receives final program surfaces and stems. It does not own calibration.

## Verification Surface

Use these as quick probes after touching the module shelf:

```powershell
dotnet build .\Mimir.slnx
dotnet run --no-build --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --perfect-machine-profile-smoke
dotnet run --no-build --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --perfect-machine-lowering-benchmark
dotnet run --no-build --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --perfect-machine-contract-smoke
dotnet run --no-build --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --perfect-machine-manifest
dotnet run --no-build --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --bioacoustic-actuator-self-test

## Cut Line

If a future implementation supersedes one of these module shapes, delete or
demote the old module in the same pass. The library is meant to keep usable
organs ready at hand, not preserve every fossil that once twitched.
