implementation_name: Mimir public surface / native runtime contracts
premise: >
Mimir is the local realtime field machine: cameras, microphones, speakers,
network feeds, and timing signals become one coherent OBS-facing volumetric
program surface. The live path is a C# Fensalir-hosted app with in-memory
rolling buffers and native capture/runtime boundaries.
objective:
primary: >
Build one synchronized spatial stream machine from six cameras, six
microphones, two speakers, Leap timing, Fensalir GPU rendering, Faust DSP,
and OBS output.
current: >
Promote the active bioacoustic packet-song receiver into runtime state:
self-identifying song contours should pin multiple time/frequency anchors
per heard call, learn per-path response, and drive the audio actuator while
direct camera/audio capture continues feeding Mimir.Runtime buffers.
constraints:
- Sender is Windows.
- Receiver uses OBS.
- Video encode must use NVENC when the bridge path is active.
- Audio sources must remain separately controllable in OBS.
- V1 bridge is LAN-only.
- Persistent state must clarify rehydrate, not become transcript tax.
- Live ingest belongs to Mimir.Runtime, native drivers, Fensalir, and
Faust/native DSP.
- Edge JSON is schema/diagnostic only; live process data is typed or in
memory.
- Networked feeds are producers into the live runtime, not independent clock
authorities.
- Mimir explicitly trades latency and memory for throughput and field quality:
the default five-second buffer is compute budget for stream alignment,
GPU/audio analysis, and volumetric sound-field extraction.
invariants:
- OBS composition authority stays in OBS.
- FFmpeg owns capture, encoding, and transport only for bridge utilities.
- One stable bridge port equals one OBS source endpoint.
- One rolling live window owns the timing edge and expiry.
- The rolling window is not accidental latency. It must preserve enough time
to line up feeds and crunch data before OBS-facing output is emitted.
- Typed views may index the rolling buffer, but no per-kind ring owns
retention.
- Fensalir owns production UI, GPU fusion, D3D12 interop, Spout2 output, and
the EVE shared D3D12 program-output texture.
- Mimir publishes physical observations, calibration constraints, and surface
intent. Fensalir owns field claims, selected lowerings, evidence reservoirs,
temporal guide lanes, and program presentation.
- Fensalir packet payload handles are not authority. Live payload references
must resolve through declared typed GPU/native resources with shape,
residency, shader access, validity, version, and handle metadata before
shader lowering can consume them.
- EVE fullscreen output must use native decode/composite over Fensalir-owned
program pixels; WebKit/DOM layout is forbidden as pixel authority.
- Faust/native DSP owns hot audio alignment, separation, spatialization, and
stems.
- Local secrets remain untracked.
- Mimir is a CultMesh app. Codebooks, schedules, calibration receipts, path
response, and compute-offload work need typed mesh-syncable state surfaces
so phones, microcontrollers, Raven, and Starfire can cooperate without
becoming independent timing authorities.
accepted_design:
- `Mimir.slnx` owns the app surface.
- `src/Mimir.App` launches Fensalir as host/window/D3D12 library.
- `src/Mimir.Runtime` owns `MimirSynchronizationHub`,
`MimirRollingStreamBuffer`, stream descriptors, `IMimirStreamSource`,
direct native ingest, process bridge ingest, and video capture driver seams.
- `MimirVideoFrameDescriptor` carries width, height, pixel format, stride,
device timestamp, and optional native/GPU handle.
- `MimirEveProgramOutputConfigurations.NativeSharedTexture` records the
EVE-facing program-output contract: Fensalir publishes
`Global\MimirFensalirProgramTexture` when
`FENSALIR_PROGRAM_OUTPUT_D3D12=1`; EVE receives decoded native pixels and
owns only final composite/input uplink.
- `src/Mimir.EveRelay` is the current EVE dashboard transport slice:
it opens the named D3D12 program-output texture, feeds low-latency H.264
(`h264_nvenc` by default), frames Annex-B access units over `/stream`, and
reports `/health`. EveCanvas uses `AVSampleBufferDisplayLayer` for native
decode/composite. The local launch script opens an SSH reverse tunnel to
Eve when Windows firewall policy blocks direct inbound TCP, and EveCanvas
tries localhost before the LAN host.
- `MimirAudioBlockDescriptor` carries sample rate, channels, sample format,
frame count, timestamp, and optional native handle.
- `MimirFrameEventProcessStreamSource` is a temporary diagnostic adapter for
JSON-line video frame and audio block metadata from native probes into
runtime rolling buffers; it does not carry pixels/audio payloads or own the
final local-device hot path.
- `MimirBioacousticTimeline` is the active runtime watermark. It renders a
low-gain birdsong-like word language with 128 self-identifying word
positions, left-speaker and right-speaker variants, four formant-rich
syllables per word, rhythm variation, and direct word identity instead of a
de Bruijn grammar. The active receiver is a song-contour anchor machine:
one heard call should expose syllable timing, contour bends, formants,
payload ornaments, speaker tint, and log-mel evidence as a cluster of
time/frequency anchors. `MimirRuntime` emits separate panned vocabularies
per speaker. `MimirAudioSynchronizationAnalyzer` reports active timing as
`evidence=bioacoustic`; the old chirp-bin path remains a
calibration/reference artifact with ASIO tooling.
- The diagnostic audio path can optionally carry base64 float sample payloads
for sync smoke tests. `MimirChirpletTimeline` owns the older structured
chirplet reference fingerprint: an order-3 de Bruijn sequence over 32
time/frequency constellation symbols, plus PCM segment rendering, matched
timing atoms, symbol/event decoding, and per-band response kernels. Symbol
identity is carried by start band, glide shape, duration, and following
inter-chirp gap. Any three consecutive correctly detected symbols identify a
timeline event within the current operating horizon. `MimirChirpletSymbolCodebook`
owns the 32 symbol definitions so every symbol has a unique chirp shape, with
rhythm as additional evidence. `MimirChirpletStreamDecoder` is the first
constrained chirplet-transform receiver: it owns a bounded PCM window, emits
transform frames with multiple phase-invariant symbol candidates and refined
per-candidate sample offsets, decodes code-valid triplet anchors through
gap/clock coherence, and fits a per-source sample clock from those anchors.
Its synthetic smoke path is `dotnet run --project
.\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --chirplet-self-test`.
It currently decodes all 15 emitted chirps in a two-second window into 13
anchors for events 0-12 with a 47999.999990 Hz clock fit and 0.000014 sample
MAE. `MimirAudioSynchronizationAnalyzer`
now treats `loopback-scarlett-speakers` as timing authority and derives
delay only from matched decoded timeline anchors. Positive delay means
the candidate mic is late relative to loopback. Reports include rounded
delay, fractional delay, confidence, and per-band matched energy. `MimirSynchronizationHub`
caches the latest per-source reports and `MimirAudioSynchronizationStateTracker`
owns the smoothed per-source belief: latest delay, smoothed delay,
confidence, per-band response evidence, and delay-slope/SRO estimate in
ppm. `MimirRuntime` now runs this analysis online as a bounded rotating
service on a fixed cadence, while UI and telemetry read cached reports/states
instead of invoking analysis. `MIMIR_SYNC_TELEMETRY_SECONDS` prints live
buffer/report/state telemetry. `MimirAudioSynchronizationSettings.Mode`
now owns the active evidence policy: `chirp-only` emits the calibration
witness, `passive` stays silent and uses program-audio phase correlation,
and `hybrid` emits active pilot chunks only while passive confidence is
weak. `MimirPassiveAudioSynchronizationEstimator` is the first passive path:
it uses PHAT-weighted cross-spectrum correlation between loopback and mic
windows before any watermark is needed. Negative passive lags are
contradictory evidence and carry zero confidence; single-window passive
confidence is capped below certainty until repeated state earns it.
`MimirBioacousticTimeline` is now the active calibration witness for both
chirp-only and hybrid: 128 self-identifying word positions, left/right
speaker variants, four formant-rich syllables per word, rhythm variation,
and direct word identity so any correctly decoded word identifies one
canonical timeline location. The analyzer refines final active delay with constrained local
waveform correlation around the decoded anchor delay. Each detected motif
carries per-band response evidence, and the next calibration cut should use
those profiles to tune contours, formants, usable bands, gain, and rhythm
weighting. `Mimir.BufferSmoke --bioacoustic-cepstral-smoke` now proves the
non-brute-force receiver direction: degraded mel-cepstral calls are decoded
by an augmented MFCC/projection-hash word index before any expensive
confirmation. `Mimir.BufferSmoke --bioacoustic-train` now runs a
receipt-backed hypothesis panel over indexed cepstral decoder shapes and
writes typed CultCache results plus pre-warp/post-warp/reconstructed WAV
artifacts under `artifacts/bioacoustic-training/`. The first receipt
`bioacoustic-20260524-103438` showed compact indexing fastest on clean
audio and exposed timing error under domain warp. The corrected receipt
`bioacoustic-20260524-150729` adds global clock hypothesis scoring over a
longer window; compact indexing wins clean throughput, baseline indexing
remains steadier under degradation, highband indexing has warped-path value,
and anchor density needs its own metric. `MimirChirpBinTimeline` remains the controlled chirp-bin
calibration/reference artifact with ASIO tooling and
`MimirChirpBinCalibrationModel`; keep those captures as response evidence,
not the active runtime sound. Reports and sync states expose delay in
microseconds as well as fractional samples. Hybrid emits the bioacoustic
witness as low-gain half-second bursts while passive confidence is weak,
never as catch-up backlog. The analyzer no longer applies the passive
two-second window floor to active fallback; `dotnet run --project
.\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --chirp-only-sync-self-test --sample-rate 48000`
recovers a 317.375-sample synthetic delay with printed 0.000 us error using
`evidence=bioacoustic`, while `--hybrid-sync-self-test --sample-rate 48000`
correctly accepts strong passive evidence at 2.772 us error. The synthetic
standalone receiver proof `--standalone-bioacoustic-self-test --sample-rate
48000 --delay-samples 1269.5` recovers delayed source time below printed
microsecond precision using only the codebook/schedule. `--bioacoustic-actuator-self-test
--sample-rate 48000 --delay-samples 317.375` now proves the first
measurement-to-sample-movement loop: estimate bioacoustic delay, apply
fractional correction, and remeasure residual below printed microsecond
precision. `faust/mimir_alignment_actuator.dsp` is the first Faust-owned
actuator surface for six channels of bounded fractional delay/gain. The synthetic
codebook proof is `dotnet run --project
.\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --bioacoustic-self-test`.
`Mimir.BufferSmoke --render-chirp-bin-f32` plus
`native/probes/asio_audio_cadence --play-f32-mono --record-f32-interleaved`
now provides a real Scarlett ASIO artifact proof for active mode. At 192 kHz,
Loopback 1 -> Loopback 2 decoded at 0.000 us with 12 anchors and 0.999
confidence. `Mimir.BufferSmoke --calibrate-chirp-bin-asio-f32` now renders
or ingests a calibration capture and persists the response/confusion/delay
model under `calibration/chirp-bin/`; `--analyze-asio-f32 --calibration`
loads it back into the chirp-bin reference decoder. Physical inputs still fail accepted
pairwise timing against loopback in the stored artifact, but decoded mic
channels now leave calibration models; physical input 1 produced two reliable
symbols and a different strongest measured band set.
`native/asio_capture` and `MimirAsioStreamSource` are now the runtime
Scarlett path: Focusrite ASIO callbacks feed sample-bearing 192 kHz Float32
blocks into `Mimir.Runtime` in process. `config/mimir-runtime.asio.example.json`
proves continuous ASIO runtime ingest: a two-second BufferSmoke run at
192 kHz ingested more than 12,000 sample-bearing blocks across `asio-ch0`
through `asio-ch3` and retained 2,048 blocks per channel, all from the
Focusrite ASIO callback stream.
`Mimir.BufferSmoke --calibrate-contestant-asio-f32` now persists the active
packet-song physical response model under `calibration/bioacoustic/`,
including per-channel delay search, polarity, payload reliability,
response-normalization bands, gain, confidence, and pairwise propagation
delay. The latest canary-packet Scarlett receipt runs at 10.7x realtime
across four 192 kHz channels: loopback is 37/37 with 2.524 us MAE,
co-streamer shotgun is 37/37 payload with 58.785 us MAE, and the cardioid
is 26/37 with 90.558 us MAE. This is a serious calibration surface, not yet
true physical microsecond sync.
A fresh 192 kHz room receipt at
`calibration/bioacoustic/scarlett-canary-packet-192k-contour-fresh.json`
keeps loopback at 2.524 us MAE, improves the co-streamer shotgun to 37/37
payload with 34.083 us MAE, and improves the cardioid to 31/37 payload
with 92.996 us MAE. The next precision cut is intra-call contour anchors,
not more sequence machinery.
`calibration/bioacoustic/scarlett-canary-packet-anchor-rich-192k.json`
is the first anchor-rich receipt: timing chips, formant pivots,
harmonic-envelope notches, payload ornaments, renderer template caching, and
per-event intra-call anchor measurements. It clears 10x realtime and
improves loopback to about 2.23 us MAE, but physical mics regress/hold at
tens of microseconds, so anchor survivability and path weighting are now the
problem.
Path-level loopback truth now compares candidate mic anchors directly
against loopback anchors, then refines delay with event-local waveform
correlation against the captured loopback packet. On the stored anchor-rich
capture, Release calibration runs at 21.1x realtime and improves physical
path precision to 7.576 us for the cardioid and 6.578 us for the shotgun.
A fresh room capture keeps the shotgun near 5.916 us but worsens the
cardioid to 18.930 us. The one-microsecond target remains open; next cut is
phase/group-delay correction or a better direct-path anchor family. A naive
recursive waveform phase-lock pass was tested and reverted because it could
improve one cardioid receipt while worsening the shotgun and locking a fresh
cardioid run onto a later reflection lobe. Recursion is only allowed back as
a constrained direct-path/group-delay model, not as unconstrained waveform
resampling with prettier decimals. The sonar/DSP research note
`research/sonar-dsp-recursive-refinement-2026-05-25.md` points the next
decoder cut at complex contour matched filters, phase-slope/group-delay
fitting, acquisition/tracking loop bandwidths, and sparse multipath
residuals. Its source ledger and local mirrors live under
`research/sonar-dsp-recursive-refinement-2026-05-25/`.
`MimirComplexContourMatchedFilterBank` and `MimirDirectPathTracker` are the
first implementation slice of that shape: complex anchor responses keep
multiple lobes, the current path prediction gates direct-path ownership, and
later coherent clusters are reported as reflection taps. Synthetic 192 kHz
reflection smoke currently lands about 5.249 us from expected delay; stored
Scarlett shotgun receipts land within about 5.860 us and 7.247 us of seeded
path fits, while cardioid receipts land within about 15.817 us and 8.963 us.
Low confidence is expected until phase/group-delay surfaces are learned. The
tracker now exposes per-band delay/phase residual observations and a
`MimirDirectPathChannelModel` correction surface for multi-window
calibration; one-window self-correction is not live authority. The tracker
now consumes explicit channel models as phase/group-delay correction and
downweights bands outside the learned usable surface. `Mimir.BufferSmoke
--learn-complex-contour-channel-model` persists
`calibration/bioacoustic/complex-contour-channel-model.json` from the
replay panel, and `--evaluate-complex-contour-channel-model` persists
`calibration/bioacoustic/complex-contour-channel-model-evaluation.json`.
Current evaluation improves 3/4 absolute path-seed errors and lowers mean
direct-cluster MAE; the fresh cardioid case reaches about 0.202 us from
seed, while the stored cardioid case still worsens to about 17.476 us. The
model is explicit calibration evidence, not default runtime authority.
The complex contour receiver is now wired into runtime as an explicit live
lane: when `enableComplexContourRuntime` is true, Mimir emits the configured
`bioacousticWitnessProfileId` through `MimirBioacousticContestantRenderer`,
loads `complexContourChannelModelPath`, extracts Float32 windows from the
rolling buffers, and publishes `evidence=complex-contour` reports. The
synthetic runtime-shaped proof `--complex-contour-runtime-self-test` at
192 kHz recovers a 693.5-sample delay with about 0.219 us error.
A fresh live Scarlett proof is preserved at
`calibration/bioacoustic/complex-contour-live-20260525-063229.md`:
Focusrite ASIO playback/capture measured Loopback 1 -> Loopback 2 at
-0.014 us with corrected confidence 0.971. The apparent `asio-ch0`
near-seed/cardioid estimate is invalidated: signal inspection shows flat
low-level noise with zero-lag loopback correlation 0.000032, so the tracker
fit noise under seeded timing pressure. `asio-ch1` remains only a weak,
non-authoritative input witness. The next cut is signal-presence gating,
independent path truth, and better frequency/direct-path discrimination.
`calibration/bioacoustic/complex-contour-replay-panel.json` persists the
current four-case replay receipt.
Acoustic robustness remains open.
The old arbitrary-chirplet matcher is a diagnostic/reference artifact only,
not the runtime hot path.
- `IMimirVideoCaptureDriver` and `MimirVideoCaptureDriverSource` are the live
seam for Leap, Media Foundation, DirectShow, libusb, LeapC, or shared
texture capture.
- `native/reservoir` owns the lower shared-edge rolling-buffer invariant for
Fensalir/Faust integration.
- `MimirFensalirFieldLowering` now emits `AquariumFieldResourceDeclaration`
rows for live payload views. Observation claims reference
`mimir:resource:*` keys, and Fensalir validation/planning can reject or
defer packets whose resource declaration is missing, CPU-only, duplicated,
or backend-incompatible. Audio spectrum/waveform surface intents now use
the source observation resource key and plan as `TubeField` packets when
the resource is compatible. `Mimir.BufferSmoke
--fensalir-field-evidence-smoke` proves one declared resource, three
claims, one planned resource-backed `TubeField` packet, two deferred
non-backend claims, and no validation errors.
`--fensalir-field-dsl-resource-smoke` proves Fensalir's field evidence DSL
can bind a declared resource directly and produce one planned `TubeField`
packet with no deferred requests. `MimirFensalirFieldLowering` also owns
the current camera observation bridge: latest video buffers lower into
FieldEvidence camera claims, GPU/native video handles declare shared
Texture2D resources, and metadata-only cadence frames do not create camera
surface intents or fake payload requests. The old direct
`AquariumGpuSensorFrame` builder is no longer the active proof path;
Fensalir can now resolve imported shared Texture2D resources by native D3D12
handle and accepts Mimir video format names such as Bgra8, Gray8, Rg8,
Nv12, and LeapStereoIr. The preferred live camera path is now
Fensalir-owned texture leasing: Mimir receives `AquariumRuntimeServices`,
asks the engine field resource broker for a keyed Texture2D lease, writes
decoded frames into the returned shared D3D12 texture, signals the returned
producer fence, and commits that fence value before the resource key reaches
shader sampling. `MimirVideoCaptureDriverSource` forwards that lease client
to direct camera drivers that implement `IMimirFensalirTextureLeaseReceiver`.
Camera backends must use the closest-to-device path available and report
unavoidable copies; process or managed convenience layers are diagnostics,
not production camera hot-path owners.
Raw single-plane system-memory frames use the explicit fallback upload lane:
`MimirVideoCaptureDriverSource` uploads the bytes into the Fensalir lease,
drops the managed payload from the live sample, and increments
`UnavoidableCopyCount`. NV12 CPU upload is rejected until Fensalir has a
real planar upload path; device/GPU NV12 producers should write the leased
texture directly.
`MimirKsVideoCaptureDriver` plus
`native/camera_capture/mimir_camera_capture.dll` is the first
production-shaped KS/UVC direct camera path: it opens a Kernel Streaming pin
in process, queues uncompressed UVC frames, and feeds the same driver source
and Fensalir lease upload path. MJPG/H264 remain future device/GPU decode
producer work.
`MimirPs3EyeVideoCaptureDriver` plus
`native/camera_capture/mimir_ps3eye_capture.dll` owns the equivalent raw
WinUSB/libusb PS3 Eye path and emits Bayer8 frames through the same upload
and copy-count machinery.
Fresh direct-driver smokes uploaded real frames for LeapUVC 640x240 YUY2,
PS3 Eye 0/1 320x240 Bayer8, Kiyo Pro 1920x1080 YUY2, and regular Kiyo
640x480 YUY2. Regular Kiyo 1280x720 YUY2 did not open; compressed
MJPG/H264 remain device/GPU decode producer work.
`Mimir.BufferSmoke --fensalir-camera-observation-smoke`
verifies the split, and `--fensalir-texture-lease-smoke` verifies the
engine-owned lease path. Camera image claims currently defer until Fensalir
has a selected visual fusion/feature extraction lowering for camera textures. Fensalir now owns the first in-process
D3D12 field resource registry: declared shared structured/curve buffers
import/alias GPU-resident resources by handle, while Fensalir-owned
resources allocate GPU slots only when Fensalir is the producer.
Mimir-declared rendering buffers are therefore Fensalir GPU resources in
the same runtime, not cross-process payload truth and not CPU payloads to
copy back and forth. The TubeField DSL can now express a 2D rolling float
buffer as Catmull-Rom XY tubes with modulo column addressing, amplitude
power/normalization, radius, ramp texture path, and emission scale.
Fensalir now has the first D3D12 TubeField compute/render lowering: compute
binds the declared rolling sample buffer as read-only GPU memory, expands
endpoint-clamped Catmull-Rom tube envelopes into fixed-budget vertex/index
UAVs, honors declared float sample stride with byte-address loads, records
one draw batch per lowering, then the TubeField pixel shader binds the
matching source buffer and resamples material per pixel by column+spline
coordinate with the cheap 5-tap approximation. Texture2D local assets are
now first-class Fensalir field resources: the DSL can declare a local PNG
ramp resource, TubeField `ramp=` aliases bind automatically by resource
key, and D3D12 uploads/binds the texture SRV with a linear-clamp sampler.
Missing ramps fall back to a Fensalir-owned 0-1 linear texture. The first
material is opaque field geometry with squared normalized emission, fake
Fresnel center-bright/edge-dark shaping, and geometry-budget overflow
reporting. TubeField compute now emits GPU-resident D3D12 indirect draw
argument packets, and render executes those packets after binding each
batch's source/ramp material state. SurfacePage resources now have the first Fensalir
resolver: engine users can declare GPU-resident 2D pages with dimensions,
format, version, and optional local source, and Fensalir allocates/binds
them as shader-readable page textures for future Height/SDF/material
lowerings. VolumeTexture resources can now be declared and resolved as
GPU-resident shader-readable 3D textures for future density/extinction/SDF3D
lowerings. Mesh resources now package friendly vertex/index ownership:
`Mesh.Vertices` and `Mesh.Indices` describe the GPU buffers, plus topology,
index format, bounds, submesh count, and version. The Fensalir DSL can
declare those mesh packages, and the D3D12 registry allocates/reuses the
backing vertex/index buffers under the mesh resource key. The DSL can also
create generic resource-backed claims, so mesh/page/volume resources can
reach backend packet planning. Mesh draw/material lowerings remain future
engine work. Mesh layout authority is split: imported/user-facing meshes use
the standard `PositionNormalUvColor` vertex layout, while generated meshes
can be `PipelinePrivate` and let the lowering own the minimal bytes.
TubeField now renders through the first explicit pipeline-private generated
mesh binding: compute owns the private vertex/index/indirect layout, and
render binds that generated mesh before applying TubeField material state.
The generated-mesh DrawIndexed indirect command signature is shared ABI now;
TubeField only owns the argument buffer it emits. TubeField expansion is now
gated by the selected backend packet plan, so lowering metadata cannot
bypass validation/planning authority. Validation also rejects TubeSpline
lowering metadata if its claim is not Tube-encoded or if its resource does
not match the claim payload. Mimir's typed surface-intent lowering now emits
TubeSpline lowering metadata for audio spectrum/waveform Tube claims, so the
generated mesh path is fed by real Mimir evidence rather than only the DSL
smoke. The legacy direct `AquariumSplineFrame` spectrum dashboard is silent:
`MimirRuntime` submits an empty spline frame and the old direct spectrum
spline builder has been deleted. Live spectrum samples are now normalized
into a row-major Float32 matrix, declared as
`mimir:resource:spectrum:field-upload`, uploaded into a Fensalir-owned
GPU-resident structured buffer, and consumed by the TubeField lowering.
`Mimir.BufferSmoke --mimir-spectrum-upload-smoke` verifies the live
`MimirRuntime` frame path emits that Float32 upload and planned TubeField
packet while direct spline and buffer-field dashboard inputs remain empty.
The runtime spectrum path also declares the local blackbody PNG as a
GPU-resident Texture2D field resource and binds the TubeField material by
`RampResourceKey`.
Runtime spectrum columns now represent flattened `(history age, source
lane)` pairs. Mimir emits one TubeField claim/lowering per active source.
The spectrum resource advertises fixed history and source-lane capacities
so frame content versions and source topology changes do not resize the GPU
buffer while the rolling trail fills. `MIMIR_SPECTRUM_SOURCE_LANES` sets
the lane capacity; surplus sources are truncated and reported in the
runtime UI. Lowerings use that capacity as `ColumnStride` through the
shared Float32 resource so each active lane renders a true age trail at
`z = age * 0.1`. Physical history slots are addressed as a ring with
`RollingOffset`, so logical age no longer requires moving every column in
the upload matrix before shader sampling. Mimir emits one Float32 resource
upload for the newest spectrum ring slot with an explicit element offset
instead of uploading the full fixed-capacity backing buffer every frame.
Fensalir owns rolling-slot validity and clamps TubeField dispatch so invalid
older slots are not sampled after renderer allocation, reset, or partial
update.
`MIMIR_SPECTRUM_TUBE_SUBDIVISIONS` controls the Mimir-requested Catmull-Rom
subdivisions so Fensalir's TubeField truncation report has a direct cost
lever. Mimir's active proof path no longer uses the direct
`AquariumAcousticFieldFrame` builder: sync states lower into FieldEvidence
calibration constraints and remain deferred until Fensalir owns a selected
acoustic visualization/fusion lowering.
- `config/perfect-machine.example.json` declares live owners, sensors,
reservoir views, and runtime policy.
- `src/Mimir.Runtime/Synchronization` now includes the Perfect Machine module
library distilled from the research notes: node profiles, decoder/language

ingest strategies, reservoir strategies, field profiles, compute offload,
OBS publication, CultMesh contracts, Fensalir lowering, and exportable
manifest generation.
- `docs/perfect-machine-module-library.md` indexes those reusable runtime
modules and their smoke commands.
- `docs/code-algorithm-map.md` is the source-level ownership and algorithm map
for the current repo code surface.
- `docs/perfect-machine-domain-index.md` indexes Mimir's full problem domain,
current evidence taxonomy, hot paths, and implementation cuts.
- `research/perfect-machine-study-2026-05-23/` preserves the architecture
rumination, optimization ledger, research references, source/hotspot audits,
Fensalir/native boundary maps, benchmark plan, calibration-session spec,
distributed receiver spec, failure-mode ledger, data dictionary, low-level
implementation notes, and sample code sketches for streaming chirp-bin
decode, AVX2/GPU scoring, batched native ABI, fractional-delay/SRO
actuation, acoustic source localization, Mimir-to-Fensalir lowering, and
native capture rings. The corrected deep-study pass ran from
`2026-05-23T23:54:42.9041588+01:00` through at least
`2026-05-24T01:54:56.9747630+01:00`; use
`research/perfect-machine-study-2026-05-23/reading-guide.md` as the
re-entry index.
- `.voidbot` state is part of repo memory and must be committed separately
whenever dirty.
active_subgoals:
- Implement the first concrete Leap direct capture driver and measure cadence.
- Add remaining local camera drivers through `IMimirVideoCaptureDriver`.
- Use the verified in-process Focusrite ASIO source for local Scarlett mic and
loopback ingest; WASAPI remains a diagnostic witness.
- Add network audio feed producers that enter the same runtime clock/rebuffer
machinery instead of becoming independent authorities.
- Bind Fensalir UI to stream health, buffer depth, source timestamps,
settings, and output management.
- Keep PowerShell/FFmpeg/SRT as bridge utilities until direct program output
replaces them.
current_status:
summary: >
The repo owns a C# Mimir app/runtime scaffold, a native reservoir crate, OBS
bridge scripts, and persistence surfaces. Script-era packages, tests,
helper tools, dependency manifests, and stale docs have been removed from
the working tree. Research archives remain as reference-only memory for raw
native/GPU implementation shape. A raw PS3 Eye libusb/WinUSB cadence probe
measured both PS3 Eyes simultaneously at about 183 fps each at 320x240 and
57-59 fps each at 640x480. A native Kernel Streaming LeapUVC probe can pull
frames through usbvideo.sys without Media Foundation, DirectShow, OpenCV, or
frame processing; after discarding a two-second warm-up, the useful 640x240
stereo IR mode advertises 115 fps and currently measures about 110.8 fps
with eight queued asynchronous KS reads. The half-height 640x120 mode
advertises 214 fps and currently measures about 205.9 fps. Plain Kiyo is
usable through KS when manual exposure is forced shorter: 1080p MJPG reaches
about 30 fps and 720p MJPG reaches about 51.5 fps. Kiyo Pro advertises 60
fps MJPG at 720p/1080p but currently delivers only about 25 fps through the
same KS path even with manual exposure tuning. Standard KS low-light
compensation off does not restore 60 fps, powerline 60Hz only raises Pro
cadence to about 29 fps, and standard extended Video HDR is not exposed on
this KS path. The controls-only probe now parses USB VideoControl
descriptors and found the Kiyo Pro's two vendor extension units. One
extension unit answers writable KS selectors. Moving the Pro directly to a
motherboard USB3 port changed the path to `root_hub30`, `bcdUSB=0x0320`,
and exposed 720p/1080p YUY2/MJPG/H264/NV12 at 60 fps, but Windows still
reports `UsbHighSpeed` rather than `UsbSuperSpeed`, and baseline cadence is
still about 25 fps across every tested format. The first simultaneous local
camera pull only had three visible devices: LeapUVC, Kiyo Pro, and one PS3
Eye. The KS multi-stream harness plus raw PS3 Eye probe pulled all three at
once, but Leap cadence collapsed under shared load: with PS3 Eye at
640x480@60 the set delivered Leap 40.12 fps, Kiyo Pro 24.99 fps, and PS3
Eye 56.06 fps; with PS3 Eye at 320x240@187 it delivered Leap 81.10 fps,
Kiyo Pro 25.33 fps, and PS3 Eye 185.74 fps. After port swapping, five
camera devices / six optical sensors were visible and pulled at once:
LeapUVC's packed stereo IR pair, Kiyo Pro, regular Kiyo, and two PS3 Eyes.
With both Eyes at 640x480@60, the set delivered Leap stereo 57.33 fps,
Kiyo Pro 24.97 fps, Kiyo 30.30 fps, PS3 Eye 0 59.59 fps, and PS3 Eye 1
57.60 fps. With both Eyes at 320x240@187, it delivered Leap stereo 81.05
fps, Kiyo Pro 24.97 fps, Kiyo 30.28 fps, PS3 Eye 0 187.60 fps, and PS3
Eye 1 187.03 fps. Kiyo Pro still negotiates high-speed USB, and Leap
remains topology-sensitive under shared load. A follow-up moved Leap alone
onto the blue rear USB3 group/root_hub30#5 while both Kiyos shared
root_hub30#7&18eea21b and one visible PS3 Eye used root_hub30#7&124f193f;
Leap still delivered only 80.99 fps with the other visible cameras active,
so the remaining loss is not explained by same-root-hub contention alone.
Splitting Kiyo Pro and one PS3 Eye to Raven left the Mimir host with
LeapUVC, regular Kiyo, and one PS3 Eye, but local cadence still stayed low:
Leap delivered 81.34 fps with Kiyo+Eye, 82.77 fps with Kiyo only, and only
84.18 fps in a same-session Leap-only baseline. The previous ~110.8 fps
Leap result was not reproduced until the Focusrite Scarlett Solo was moved
away from the Leap USB neighborhood. After that, Leap-only baseline rose to
95.48 fps, best full-height scenario to 101.67 fps, and the local split set
delivered Leap 105.10 fps, regular Kiyo 30.17 fps, and one PS3 Eye 185.81
fps. The split-host layout is viable if the Leap's USB neighborhood stays
free of the Focusrite and other heavy devices. Raven's PS3 Eye raw interface
now has the same libwdi WinUSB binding as the local Eye and can be opened by
the copied cadence probe, but Raven Eye cadence is currently unusable:
320x240@187 delivered 132.24 fps then 78.93 fps, and 640x480@60 delivered
6.32 fps with multi-second gaps. Moving that Eye back to the Mimir host
produced the current clean local topology: LeapUVC, regular Kiyo, and two
PS3 Eyes run in parallel while Kiyo Pro stays off-host. With both Eyes at
320x240@187, Leap delivered 106.07 fps, Kiyo 30.33 fps, and the Eyes 186.57
/ 186.14 fps. With both Eyes at 640x480@60, Leap delivered 108.07 fps, Kiyo
30.34 fps, and the Eyes 57.79 / 58.08 fps. Moving Kiyo Pro back to the
Mimir host while regular Kiyo was absent kept Leap healthy: with both Eyes
at 320x240@187, Leap delivered 110.80 fps, Kiyo Pro 24.97 fps, and the Eyes
187.46 / 186.89 fps; with both Eyes at 640x480@60, Leap delivered 110.72
fps, Kiyo Pro 24.87 fps, and the Eyes 59.91 / 59.19 fps. Kiyo Pro still
negotiates UsbHighSpeed(2), but it does not poison Leap cadence in the
current layout. Moving regular Kiyo from front panel to a rear port made
all five camera devices / six optical sensors visible locally. With both
Eyes at 320x240@187, the full set delivered Leap 110.84 fps, Kiyo Pro 25.08
fps, Kiyo 30.18 fps, PS3 Eye 0 187.59 fps, and PS3 Eye 1 187.02 fps. With
both Eyes at 640x480@60, it delivered Leap 110.76 fps, Kiyo Pro 25.14 fps,
Kiyo 30.18 fps, PS3 Eye 0 59.66 fps, and PS3 Eye 1 59.95 fps. A mouse in
the Leap USB neighborhood does not reproduce the Focusrite-induced collapse.

Use the new bioacoustic timeline watermark as the active acoustic sync
direction. Cut the next implementation in this order: streaming indexed
log-mel/MFCC motif decoder state with a global clock/path hypothesis fed by
`--bioacoustic-train` receipts, calibration-session command/replay proof that learns
per-output/mic motif/formant response, fractional-delay/SRO actuator, then
native camera payload handles and Fensalir lowering. Keep chirp-bin
calibration captures as reference evidence, not the runtime target.
Current app testing proves Fensalir WASAPI output wakes Scarlett speaker
loopback, live mic buffers stay populated, runtime sync analysis now runs as
a bounded rotating service without UI/telemetry re-entry, and the bioacoustic
motif timeline produces deterministic synthetic active sync. The next
invariant is self-identifying song contours producing stable intra-call
time/frequency anchors and clock fits through real loopback and microphones,
so the actuator can use decoded time instead of filtered lag guesses.
Replace the remaining
diagnostic JSON-line process bridges with direct native capture drivers that
push buffer handles into Mimir.Runtime. Mimir.BufferSmoke still proves live buffers and sync reports
for Scarlett loopback, Focusrite mic, Kiyo mic, and Kiyo Pro mic when
calibration witnesses are playing. Treat PS3 Eye audio as
enumeration/runtime-fragile, not unavailable. Keep the Focusrite away from
the Leap USB neighborhood. The Scarlett Solo 4th Gen is now attached to
Starfire, and `native/probes/asio_audio_cadence` proves local Focusrite USB
ASIO access with 4 inputs / 2 outputs including Loopback 1/2, 192-frame
preferred buffers, 44.1-192 kHz support, and nonzero 4-channel Int32LSB
input callbacks at 192 kHz. Raven also has a 192 kHz loopback-capable
Scarlett for co-streamer/game timing evidence, but Starfire owns the heavy
soundfield and sensor-fusion work. Treat Kiyo Pro as a ~25 fps source until
its SuperSpeed negotiation is fixed.
