+- `MimirNativeReservoirRuntime` is the managed owner for that native runtime

+- The realtime Move witness path uses CultMesh streaming, not CultCache polling:
+  Muninn publishes shared-memory stream frames, Mimir consumes the latest read
+  lease, normalizes the frame, and admits it to native `move_evidence`.
+- `MimirMuninnMoveEvidenceAdapter.TryAdmitLatestCultMeshFrame` now exposes a
+  typed admission receipt for that latest read: decoded frame id, producer,
+  publish/read timestamps, sample counts by kind, source/arrival ranges, native
+  reservoir handle, and reservoir edge/window. `Mimir.BufferSmoke
+  --muninn-move-cultmesh-stream-smoke` asserts the receipt so the named proof
+  spine can be traced instead of inferred.
+- `mimir.move_controller_pose.v1` is Mimir's resolved wand pose contract.
+  Mimir owns calibration, association, triangulation, IMU fusion, prediction,
+  confidence, and latency accounting for those poses before Fensalir consumes
+  them as interactive controller input.
+- `MimirMoveFusion` is the first calibrated fusion owner for Move tracking:
+  it consumes native Muninn Move evidence samples, requires calibrated camera
+  witnesses before publishing a pose, associates marker candidates with the
+  USB controller state, triangulates multi-camera orb position, demotes
+  single-ray fallbacks through confidence, carries buttons/trigger/gyro into
+  `mimir.move_controller_pose.v1`, and marks orientation as
+  `orientation:imu-unresolved` until the IMU/prediction pass earns full 6DoF.
+- `MimirMovePoseStream` frames resolved Move poses as
+  `mimir.move_controller_pose_stream_frame.v1` over CultMesh shared-memory
+  bytes streams so Fensalir and other consumers have a realtime stream contract
+  for Mimir-fused controller input.
+- `MimirMoveProofSurface` is the observer-only dev proof surface for the named
+  Move chain. It combines a Muninn evidence admission receipt with a Mimir pose
+  stream frame and a Fensalir presentation/probe timestamp into
+  `mimir.move_proof_surface.v1`, then lowers the verdict to a Fensalir
+  `AquariumSplineFrame` probe. `Mimir.BufferSmoke --move-proof-surface-smoke`
+  proves the explicit
+  `muninn:nightwing:move-evidence:79 -> mimir:starfire:move-evidence:79 ->
+  mimir:starfire:move-pose:79 -> fensalir:starfire:presented-frame:79` chain,
+  and rejects single-ray fallback as not full pose.
+- `MimirMoveProofPipeline` is the shared commit primitive for the live Move
+  proof path. It starts from a Muninn CultMesh shared-memory evidence frame,
+  admits samples to the native `move_evidence` reservoir, runs Mimir-owned
+  fusion, creates the Mimir pose stream frame, creates the proof surface, and
+  returns the Fensalir spline probe in one pass. `Mimir.BufferSmoke
+  --move-proof-pipeline-smoke` proves that shape against the native reservoir
+  debug DLL; live hardware and presented-frame capture still need to call this
+  primitive instead of hand-assembling a parallel path.
+- `MimirRuntime` is now the live Fensalir attachment point for proof surfaces.
+  `PublishMoveProofSurface` accepts the Mimir-owned
+  `mimir.move_proof_surface.v1` document, `CreateFrame` composes its
+  observer-only `move-proof-*` splines into `AquariumFrame.Scene.SplineFrame`,
+  and `Mimir.BufferSmoke --move-proof-runtime-frame-smoke` proves the frame is
+  empty before publish, contains the proof splines after publish, and clears
+  without leaving a repair loop behind.
+- `MimirMoveProofRuntimeDriver` is the bounded runtime bridge from a Muninn
+  CultMesh shared-memory evidence ring to `MimirRuntime.PublishMoveProofSurface`.
+  It derives the Mimir evidence, Mimir pose, and Fensalir frame ids from the
+  actual Muninn frame suffix, calls the shared proof pipeline, and suppresses
+  duplicate frame admission. `Mimir.BufferSmoke --move-proof-runtime-driver-smoke`
+  proves `MimirRuntime.Update` can pull one ring frame into the same-sequence
+  proof chain and visible spline frame.
+- `MimirMoveProofRuntimeConfiguration` is the typed runtime configuration and
+  validation contract for future real Move proof subscriptions. An enabled
+  source names the Muninn evidence stream, native reservoir path, Mimir evidence
+  and pose frame prefixes, Fensalir presented-frame prefix, fusion authority,
+  consumer contract, and at least two calibrated camera witnesses. It creates
+  `MimirMoveProofRuntimeDriver` only after the supplied ring stream id matches
+  the configured evidence stream.

+  resources, and exposes an activation status. The default provider fails
+  explicitly because the current C# CultMesh ring is still in-process only;

+  proof chain. Real Nightwing/Starfire cross-process ring opening remains
+  pending.
+- `mimir.move_proof_runtime_activation.v1` is the typed readiness/proof-spine
+  surface for configured Move proof sources. It reports the configured stream,
+  provider kind, active/driver state, native reservoir path, calibrated camera
+  ids, latest same-stream proof ids, latest verdict, and the unavailable
+  default-provider diagnostic. `Mimir.BufferSmoke
+  --move-proof-runtime-activation-surface-smoke` proves both an active injected
+  ring document and the inactive default runtime document without claiming live
+  field evidence.
+- `mimir.move_proof_evidence_frame_snapshot.v1` is the one-copy fallback for
+  captured Muninn evidence frames while C# CultMesh has no cross-process ring
+  opener. A configured `EvidenceSnapshotPath` is loaded by
+  `MimirConfiguredMoveProofEvidenceRingProvider`, metadata-checked against the
+  encoded payload, copied into an owned in-process ring, and then consumed by
+  the same runtime driver/pipeline. `Mimir.BufferSmoke
+  --move-proof-runtime-snapshot-smoke` proves the named proof spine through
+  that file boundary. It is field capture/replay support, not the final live
+  shared-memory proof.
+- Odin/Muninn now has the matching producer-side latest snapshot writer:
+  `--move-evidence-snapshot <path>` writes the Mimir-compatible
+  `mimir.move_proof_evidence_frame_snapshot.v1` artifact from the same Muninn
+  Move evidence publisher after the frame payload is accepted into the stream
+  ring. The Odin unit
+  `move_evidence_snapshot_writes_mimir_compatible_frame_artifact` decodes the
+  snapshot tuple and embedded Muninn frame payload. This lets Nightwing produce
+  a field artifact for Mimir replay while the final live ring/page transport is
+  still pending.
+- `MimirMoveProofDevSurface` is a dev-only bootstrap gated by
+  `MIMIR_MOVE_PROOF_DEV_SURFACE`. It uses the same runtime proof attachment so
+  `Mimir.BufferSmoke --move-proof-presented-frame-smoke` can run `Mimir.App`
+  headless, capture the Fensalir-presented PNG, and pixel-check the named
+  proof probe. This verifies the renderer/probe layer; it is not live
+  Nightwing hardware evidence.
+- `MimirMoveCalibrationProtocol` publishes the typed calibration preflight for
+  Starfire/Nightwing Moves: required Muninn evidence streams, optional
+  Quest headset/controller pose witnesses, stillness/sweep/validation phases, and
+  the four derived calibration outputs Mimir must produce before IMU
+  orientation can become authority.
+- Muninn publishes Quest access as `muninn.quest_access.v1` for the USB-attached
+  Quest. Mimir consumes that access surface and later `muninn.quest_pose_frame.v1`
+  samples as optional calibration evidence; Mimir does not own ADB/Quest access.
+- The old `scripts/start-nightwing-move-tracking.ps1` bring-up path is
+  archived. It no longer starts a receiver/recorder pair or stages a socket
+  witness worker. Nightwing Eye/Move evidence must enter through Muninn/Mimir
+  typed CultMesh stream frames and Odin-discovered CultMesh documents. The blob
+  stream remains optical witness evidence for later pose fusion, not the final
+  6DoF pose owner.
+- Structured PS Move light pulses are Muninn output commands. Mimir publishes
+  `muninn.move_light_command.v1` over CultNet/CultMesh to the Muninn daemon on
+  the host that owns the USB-attached Move. Muninn writes PS Move HID report
+  `0x06` locally and updates command state/receipt.
+  `scripts/start-starfire-move-light.ps1` and Nightwing direct HID writes are
+  now smoke/bootstrap paths for hardware proof when Muninn is not yet running
+  on that host.
+- Odin's Muninn organ owns Move optical candidate extraction in
+  `E:\Projects\Odin\crates\muninn-move-tracker` and publishes/feeds
+  `muninn.move_marker_candidate.v1` records. Mimir consumes those candidate
+  streams; it does not own raw optical extraction. Final pose, stereo
+  triangulation, calibration, association, IMU fusion, and prediction belong to
+  Mimir.
+- Muninn's Move evidence stream frame no longer hardcodes an empty optical
+  candidate slice. The daemon frame uses the canonical
+  `muninn.move_marker_candidate.v1` record shape, and the Odin unit
+  `move_marker_candidates_publish_in_mimir_compatible_cultmesh_frame` proves a
+  bright Y8 frame can pass through `muninn-move-tracker` and serialize as a
+  non-empty marker candidate beside controller evidence. The daemon now has a
+  source-local Y8 extraction/publish seam and a first `serve` camera producer:
+  `--move-marker-camera <camera-id>=<device-path>` polls a Unix V4L2 YUYV frame,
+  converts it to compact Y8, and feeds that same seam. Unit tests prove the
+  configured camera tick publishes marker evidence through the shared frame
+  contract; Nightwing hardware/live V4L2 proof is still pending.

 ## Next
 
+Before expanding Muninn media or Sleipnir input transport, apply the traffic
+contracts distilled in
+`docs/research/moonlight-muninn-sleipnir-study-2026-07-16.md`: latest-state,
+ordered-edge, video-deadline, audio-playout, and reliable-control. Preserve the
+existing Muninn packetizer/feedback foundations. The first implementation pass
+should make input supersession and edge preservation structural, replace the
+two-second media default with consumer-derived field budgets, and prove the
+result under controlled loss/jitter/reorder before changing carriers.
+
+The first cut landed in Odin on 2026-07-16: experimental CultLib snapshot
+`8965f3c0`, epoch/sequence/edge-ack HID delivery, 100 ms default LAN media
+deadline, CultNet `realtime` A/V delivery, bounded queues, expiring/late-aware
+repair, and decode-chain-owned keyframe pressure. The production video path now
+uses typed V4 Cauchy GF(256) FEC in independent 8-data/4-parity blocks. Each
+block schedules data and parity as separate lanes, including fixed protection
+for a short tail block. Canonical video and parity use CultNet's unreliable
+`realtime` lane; selective repair and IDR recovery remain deadline-bound.
+Canonical AAC ADTS audio and its fixed 864-byte parity shards also use
+`realtime`; 4+2 FEC, 120 ms reorder, and
+concealment own continuity without an ACK/retransmit window. Sender access units enter the
+handoff queue independently, and CultMesh catalog publication runs outside the
+realtime media loop. Repair material becomes available when a video frame enters
+the queue, and the receiver may issue bounded repair requests at 64/96/128 ms.
+The remaining work is duplicate/reconnect acceptance, longer iid runs, and the
+long-duration mixed soak.
+
+The socket harness and bounded PCM loss recovery have now landed. Odin's
+`cultnet-impair` proxy supplies deterministic seeded loss/burst/reorder/
+duplicate/jitter/stall profiles around real CultNet endpoints. Muninn emits a
+typed fixed 4+2 audio parity block after each four constant-size PCM packets;
+the production Mimir OBS receiver reconstructs up to two missing packets inside
+the 40 ms reorder budget and feeds them through the existing playout owner.
+Both sides use the experimental CultLib/CultMesh snapshot lineage used by Eve,
+Aetheria, and VoidBot; no stable-branch transport shim was introduced.
+
+Receiver pressure now closes into the long-lived NVENC encoder as bounded AIMD
+bitrate control. Startup begins at half of the configured encoder ceiling
+because fixed block parity can roughly double wire rate, and additive recovery
+is capped at half of that configured ceiling. Late/decode/repair/queue
+pressure backs off by 15 percent; clean recovery adds one-fiftieth of the safe
+cap only after ten stable seconds. The live encoder proof reconfigured 12 Mbps to 6 Mbps without a
+restart and emitted the required transition IDR. The exact remaining completion
+gate is tracked in
+`docs/research/moonlight-reliability-acceptance-2026-07-16.md`; no cross-host
+claim is allowed until its Raven-to-Starfire field matrix passes.
+
+The production receiver follow-up fixed two contract contradictions: early
+video repair no longer declares the frame late (which had made Odin discard all
+repair requests), and the OBS audio decoder now consumes Muninn's actual float
+PCM contract rather than treating it as AAC. Audio reorder is bounded to 40 ms
+with short silence concealment. The next audio cut is Opus with explicit
+FEC/PLC for variable-rate compressed audio; PCM now has bounded 4+2 erasure
+recovery plus concealment. The controllable video encoder owner now exists and
+forces the next NVENC frame to IDR without restarting the video session. A live
+D3D11 desktop proof verified the command-generated IDR. The Raven bundle and
+OBS receiver are now deployed over the direct LAN route. Raven activation is an
+interactive-token scheduled task whose PowerShell action uses
+`-WindowStyle Hidden`; no WireGuard path or foreground terminal is part of the
+runtime. The active field cut uses D3D11/NVENC video, WASAPI loopback audio,
+typed CultNet media, and the experimental CultLib lineage. The named direct and
+proxy impairment profiles and long soak remain the completion gate.

+# Mimir Program Composition
+
+## Objective
+
+Mimir owns the live stream program: selected capture feeds, calibration feeds,
+scene composition, preview/control surfaces, stats, and publication. OBS is a
+temporary compatibility sink only.
+
+## Authority Map
+
+- Owner: Mimir owns the program scene graph and subscription policy.
+- Inputs: Muninn-published local and remote monitor, window, camera, audio,
+  loopback, and health streams.
+- Outputs: a Mimir program video surface, aligned audio stems or final bus,
+  and a Yggdrasil-facing site publication feed.
+- Derived state: OBS receives a compatibility feed when useful; it does not own
+  scene truth, broadcast truth, preview truth, stats, source selection, or
+  publication.
+- Forbidden writers: OBS scenes, browser dashboards, site daemons, and Muninn
+  capture hosts must not independently decide the program composition.
+- Shared paths: direct operator edits, remote commands, preset loads,
+  calibration-driven source selection, and recovery scripts must commit through
+  the same Mimir scene graph command surface.
+- Deletion line: old OBS-owned composition docs and config names are demoted to
+  diagnostic bridge language. Any OBS adapter delegates to the Mimir program
+  scene instead of carrying its own opinion.

+  `muninn:starfire:window:discord`;
+- source kind, such as monitor, window, camera, network monitor, or generated
+  Mimir visual field;
+- visibility, layer order, transform, crop, and optional chroma key;
+- enough timing identity for Mimir to align media inside the rolling window.
+
+The current OBS scene can be mirrored as an initial Mimir scene:
+
+- Starfire monitor capture, cropped at the bottom when needed.
+- Discord window capture, cropped to chat and keyed with chroma filters.
+- Raven primary monitor plus Realtek loopback as a subscribed remote Muninn
+  stream.
+- Mimir/Fensalir program texture as a generated layer when the field renderer is
+  active.
+
+After import, OBS is not the editor of record. It may display the Mimir program
+feed, but operator edits happen through Mimir command surfaces.
+
+## Site Publisher
+
+The Yggdrasil-facing publisher consumes Mimir program output and publishes it to
+the GameCult site. It owns transport, encoding/session state, reconnect policy,
+and public edge health. It does not own composition.
+
+The publisher's input contract is the same Mimir program output used by local
+preview and OBS compatibility adapters, so the public stream cannot silently
+diverge from the operator preview.

+# Move Calibration Protocol
+
+Mimir owns Move calibration and sensor fusion. Muninn owns source-local facts:
+camera marker candidates, USB controller IMU/button state, and local Move light
+commands. Odin discovers and projects the surfaces. Fensalir consumes Mimir's
+resolved poses after Mimir has earned them.
+
+## Current Stream Shape
+
+- Starfire should run Muninn as a local capture/control daemon. Its Move stream
+  address is `muninn:starfire:move-evidence`.
+- Nightwing runs Muninn for its USB Move and local camera witnesses. Its Move
+  stream address is `muninn:nightwing:move-evidence`.
+- Mimir on Starfire publishes resolved pose frames at
+  `mimir:starfire:move-controller-poses`.
+- Quest can participate as an external tracked VR reference over USB:
+  `quest:usb:headset-pose`, `quest:usb:left-controller-pose`, and
+  `quest:usb:right-controller-pose`.
+- Starfire ASIO/Scarlett loopback can provide cue timing, but it is not a Move
+  pose authority.
+
+The Move hot path is CultMesh stream frames. On the same host, those frames use
+shared-memory bytes rings. Across hosts, the remote peer still crosses the
+Verse/network boundary. The current Raven program media bridge is not same-host
+zero-copy into Mimir/Fensalir; it sends CultNet/CultMesh media documents and
+lowers to local UDP for OBS compatibility.
+
+## Required Capture Phases
+
+1. `preflight-streams`: hold both Moves still and visible; prove stream freshness,
+   clock skew, and controller ids.
+2. `dark-stillness`: lights off, both Moves still; estimate gyro bias, gravity,
+   and magnetometer baseline.
+3. `lit-stillness`: light one Move at a time, then both; map light commands to
+   controllers and measure centroid stability.
+4. `axis-sweeps`: slow pitch/yaw/roll sweeps; fit gyro scale, accelerometer
+   frame, and optical angular consistency.
+5. `figure-eight`: broad figure-eight motion; fit magnetometer hard/soft iron
+   and cross-axis coupling.
+6. `quest-reference`: optional Quest headset/controller reference with the Move
+   between the two Quest controllers in front of the headset.
+7. `validation-pass`: held-out free motion; promote only if triangulated optical
+   residuals and IMU prediction residuals pass.
+
+## Quest Access Preflight
+
+The Quest must be authorized for USB debugging before Starfire Muninn can query
+it. Muninn owns the access surface:
+
+```powershell
+muninn serve --store C:\Meta\Odin\state\muninn.telemetry.cc --host starfire --quest-adb --quest-serial 1WMHHB68PG1515
+```
+
+When the Quest is authorized, Muninn publishes `muninn.quest_access.v1` and
+advertises `muninn:<host>:quest-input`, `muninn:<host>:quest-poses`, and
+`muninn:<host>:quest-warped-video-input`. Mimir consumes the access/pose
+surfaces as calibration evidence; it does not own Quest USB access.
+
+```powershell
+muninn quest-access-status --store C:\Meta\Odin\state\muninn.telemetry.cc
+```
+
+ADB authorization proves USB access, device identity, and basic headset state
+only. It does not expose Quest headset or controller poses; those still require
+a Quest/OpenXR witness bridge that publishes pose samples through Muninn. The
+current calibration protocol can still run without Quest, but Quest poses are
+the preferred external reference when the headset and both controllers are
+sitting around the Move.
+
+## Data Products
+
+- `mimir.move_fusion_rig_calibration.v1`: camera intrinsics/extrinsics, clock
+  association policy, and gyro unit scale.
+- `mimir.move_imu_calibration.v1`: per-controller gyro bias/scale,
+  accelerometer gravity frame, magnetometer correction, and noise estimates.
+- `mimir.move_controller_identity_map.v1`: stable association between Muninn
+  USB ids, light receipts, and optical orb identities.
+- `mimir.move_calibration_receipt.v1`: sample counts, residuals, rejected
+  phases, and promotion decision.
+
+## Optical Sphere Fit Authority
+
+`MimirMoveSphereCalibrationFitter` owns the bounded two-Eye optical fit after a
+collection session reaches `Fitting`. Eye 0 defines the tracking-space gauge.
+The fitter jointly estimates both focal lengths and Eye 1's rigid pose from
+same-frame, same-Move correspondences, using a deterministic 80/20 training and
+held-out partition. A robust training consensus may reject contaminated marker
+pairs, but promotion also requires at least 65 percent of the untouched
+held-out pairs to agree and must pass the session's median and P95 reprojection
+limits.

+That writes the typed protocol as `mimir.move_calibration_protocol.v1` into a
+CultCache receipt. The real hardware runner should consume this document plus
+Muninn's `muninn.quest_access.v1` when Quest is available, then append capture

+# Moonlight lessons for Muninn streaming and Sleipnir input
+
+Date: 2026-07-16  
+Upstream examined: `moonlight-stream/moonlight-common-c` commit `82e25148549d249a80aaf4afc68e2abb07072edf`
+
+## Verdict
+
+Moonlight is strong because it does not ask one transport policy to serve every
+realtime signal. It gives video, audio, control, and input different loss,
+ordering, recovery, and freshness rules, then keeps each queue bounded by what
+the user can still perceive.
+
+Muninn is not missing all of that machinery. Its media packetizer already owns
+access-unit boundaries, timestamps and deadlines, video parity, dependency and
+keyframe metadata, bounded assembly, receiver damage feedback, repair caching,
+and keyframe requests. Sleipnir already rejects regressing sequence/timestamp
+pairs, expires reliable HID sends after 25 ms, reports stage latency, and
+neutralizes stale output.
+
+The 2026-07-17 field cut closes most of the original mechanism gaps:
+
+- canonical video and video parity use the unreliable `realtime` lane; typed
+  8+8 GF(256) blocks, selective repair, and decode-chain IDR recovery own loss;
+- canonical 10 ms PCM audio uses `realtime`, with 4+2 FEC, a 40 ms reorder
+  owner, and short concealment; reliable delivery is reserved for control;
+- the consumer deadline is 100 ms by default and 250 ms in the Raven field
+  profile; queues, retransmits, repair material, and assemblies derive from it;
+- receiver pressure actuates the live NVENC encoder through multiplicative
+  backoff and conservative additive recovery; startup begins at half the
+  requested ceiling because fixed video parity can roughly double wire load;
+- Sleipnir latest state and ordered edges have distinct epoch/sequence and
+  application-ack semantics, including bounded overflow rebase.
+
+The remaining claim boundary is evidence: direct and impaired Raven-to-
+Starfire soaks, reconnect repetition, A/V skew measurement, and a live virtual
+HID exercise. The machine is no longer missing a named owner for these paths;
+it still has to prove those owners under pressure.
+
+Do not transplant Moonlight wholesale. Distill its ownership model into the
+existing typed Muninn/Sleipnir pipeline.
+
+## Authority map
+
+### Muninn media
+
+- Owner: Muninn owns source-local capture, encoding child lifecycle, media
+  packetization, repair material, and sender feedback response.
+- Inputs: encoded H.264/H.265 access units, encoded audio packets, source media
+  timestamps, configured latency target, and receiver feedback.
+- Outputs: typed video chunks/parity, audio packets, recovery/keyframe actions,
+  and transport/quality telemetry.
+- Derived state: RUDP acknowledgements, resend counters, CultCache receipts, OBS
+  local lowering, and operator cards are evidence or delivery substrate. They do
+  not own media deadlines.
+- Forbidden writers: generic RUDP retry policy must not decide whether expired
+  media is still useful; OBS must not decide stream synchronization; persistence
+  must not become a hot media queue.
+
+### Sleipnir input
+
+- Owner: Sleipnir owns selection/remapping and local virtual-HID emission.
+  Muninn owns source-local device sampling and event classification.
+- Inputs: a discovered Muninn input stream, typed mapping intent, monotonic
+  stream sequence, source-local capture time, and receive time.
+- Outputs: local virtual-HID state plus latency/freshness receipts.
+- Derived state: the latest full controller snapshot is replaceable state.
+  Button transitions, text/code points, connect/disconnect, and neutralization
+  are non-replaceable edges until acknowledged or superseded by an explicit
+  state transition.
+- Forbidden writers: generic reliable queue order must not replay stale analog
+  or motion samples; wall-clock subtraction must not claim one-way latency
+  without a clock model; the telemetry/store path must not repair a missing hot
+  stream.
+
+## What Moonlight actually does
+
+### It separates stream semantics
+
+Moonlight receives video and audio over UDP/RTP-like paths while input travels
+through its control path (or a legacy TCP socket). The important lesson is not
+the literal socket choice. It is that the queues have different contracts.
+Video is frame/dependency oriented; audio is short-block continuity oriented;
+input is event/state oriented.
+

+
+### Video recovery is dependency-aware and deadline-shaped
+
+The video queue groups packets by frame and FEC block, tracks missing data,
+reconstructs recoverable blocks with Reed-Solomon parity, rejects old/replayed
+frames, and advances frame authority explicitly. Depacketization can request an
+IDR when damage makes the predictive chain unsafe. The system repairs useful
+frames and abandons poisoned dependency chains; it does not wait forever for
+generic reliable delivery.

+
+### Audio recovery is a small bounded continuity problem
+
+Moonlight groups audio into fixed FEC blocks, orders packets by RTP sequence,
+recovers missing shards, detects out-of-order behavior, and changes how long it
+waits based on observed reordering. When recovery cannot complete in time, it
+allows a discontinuity and lets the audio decoder's concealment path carry the
+scar. It does not turn late audio into permanent latency.
+
+Source: [audio FEC and reorder queue](https://github.com/moonlight-stream/moonlight-common-c/blob/82e25148549d249a80aaf4afc68e2abb07072edf/src/RtpAudioQueue.c) and

+
+### Input reliability is constrained by semantic coalescing
+
+Moonlight has one send thread and a bounded queue, but it avoids blindly sending
+every sampled value. Relative mouse motion is accumulated, absolute pointer
+motion keeps the newest position, pen hover/move keeps the newest compatible
+event, controller analog state is merged while button changes split batches,
+and sensor motion keeps the newest value per sensor. A roughly millisecond-scale
+batching opportunity can reduce latency by preventing ENet queue buildup.
+
+This is the most important Sleipnir lesson: reliable delivery is safe only after
+replaceable state has been collapsed and edges have been preserved.
+
+Source: [input batching and send queue](https://github.com/moonlight-stream/moonlight-common-c/blob/82e25148549d249a80aaf4afc68e2abb07072edf/src/InputStream.c).
+
+### It exposes failure to the owning layer
+
+Packet loss, FEC recovery/failure, queue overflow, frame loss, and keyframe need
+are explicit signals. Moonlight's public documentation also warns that allowing
+frames to queue for smoothness can create high latency; its balanced mode keeps
+only about one frame for jitter smoothing. The machine treats queue depth as a
+product decision, not an incidental container property.

+
+## Current Muninn/Sleipnir comparison
+
+| Concern | Moonlight | Muninn / Sleipnir now | Distilled judgment |
+|---|---|---|---|
+| Video unit | Encoded frame, FEC blocks, dependency recovery | Encoded access unit, chunks/parity, frame/dependency IDs, deadlines | The conceptual unit is already correct. Keep it. |
+| Video loss | FEC first; abandon damaged/obsolete work; request IDR | Typed 8+8 block FEC, deadline-bound repair, completed-frame tombstones, IDR actuation | Same ownership pattern; field loss ratios and parity overhead remain tunable. |
+| Audio loss | Small FEC blocks, reorder-aware wait, decoder concealment | Realtime 4+2 PCM FEC, 40 ms reorder, bounded concealment | Mechanism is closed; Opus FEC/PLC is a later efficiency/quality cut. |
+| Congestion | Stream-specific queues and feedback behavior | Half-ceiling startup, 15% pressure backoff, bounded additive ramp, fresh media ahead of repair | Closed loop exists; impairment evidence decides its final constants. |
+| Latency budget | Minimal queueing; frame pacing explicitly trades latency for smoothness | Consumer-owned 100 ms default/250 ms Raven proof; 25 ms HID expiry | Correct owner and bounded values; glass-to-glass measurement remains. |
+| Input state | Coalesces replaceable motion/sensor/analog values | Epoch-scoped latest state supersedes stale state | Structural rather than polling-accidental. |
+| Input edges | Button/type changes terminate batches; text is ordered | Ordered edge sequence, application ACK, bounded replay, epoch rebase | Structural; live virtual-HID impairment proof remains. |
+| Staleness | Queue construction prevents much stale work | Receiver drops regressing timestamps and neutralizes after timeout | Keep the guard, but move freshness authority earlier into enqueue/supersession. |
+| Timing | RTP/media clocks and local queue timing | source Unix nanoseconds plus receiver instants | Use monotonic source time plus an explicit clock-offset/uncertainty model; do not call raw wall-clock subtraction latency. |
+| Security | Authenticated encryption in modern stream generations | CultNet typed transport policy varies by lane | Preserve typed schemas, but specify replay/authentication guarantees for hot media and HID lanes. |
+
+## Recommended cut
+
+### 1. Define traffic classes before changing transport
+
+Add one narrow typed delivery policy shared by Muninn and Sleipnir:
+
+- `state-latest`: analog axes, pointer position, gyro/accelerometer samples;
+- `edge-ordered`: button/key transitions, text/code points, device lifecycle;
+- `media-video`: dependency-bearing access units with decode deadlines;
+- `media-audio`: continuity blocks with playout deadlines;
+- `control-reliable`: subscriptions, mappings, capability negotiation, and
+  keyframe requests.
+
+This is not a generic router. It is a finite statement of the five contracts the
+existing machine already has. Each class must name supersession, ordering,
+expiry, recovery, and observability.
+
+### 2. Cut the two-second realtime default
+
+Derive deadlines from the actual consumer:
+
+- Sleipnir state-latest: tens of milliseconds, with replacement before send;
+- input edges: reliable until acknowledged, but compacted against later
+  authoritative state where safe;
+- interactive video: frame/decode budget, initially test 50–150 ms on LAN;
+- audio: playout budget, initially test 40–100 ms on LAN;
+- Mimir's five-second analysis reservoir remains Mimir compute budget, not a
+  network permission to deliver old frames.
+
+The exact values must be earned by field traces. The ownership change is not
+optional: transport retry duration becomes derived from the media/input
+deadline, never the other way around.
+
+### 3. Make Sleipnir freshness structural
+
+Split the hot input frame into:
+
+- a latest-state snapshot with `state_sequence`, source monotonic capture time,
+  and supersedes-through sequence;
+- an ordered edge list with its own sequence range;
+- receiver acknowledgement of the highest applied state and edge sequence.
+
+Muninn may overwrite an unsent latest-state snapshot. It may not overwrite an
+unacknowledged edge. Sleipnir applies edges in order, applies only the newest
+state, and neutralizes on a named lease timeout. Manual, remapped, replayed, and
+live paths must use the same commit primitive.
+
+### 4. Close Muninn's feedback loop
+
+Receiver feedback should drive named sender decisions:
+
+- request/force keyframe after unrecoverable dependency loss;
+- choose repair only when estimated arrival precedes frame deadline;
+- tune parity within a bounded profile from recent burst-loss evidence;
+- reduce encoder bitrate/pacing when queue delay grows;
+- expose encode, queue, network, assembly, decode, and presentation stages
+  separately.
+
+Do not add a second congestion controller beside generic RUDP and hope the two
+argue productively. Media policy owns the send budget; RUDP exposes delivery
+mechanics and obeys the deadline.
+
+### 5. Prove it on the layer the user feels
+
+Build one loss/jitter/reorder test harness and record timelines for:
+
+- controller press and release during 1%, 5%, and burst packet loss;
+- high-rate analog/gyro motion under an artificial sender stall;
+- video dependency loss and keyframe recovery;
+- audio burst loss and concealment;
+- queue growth under bitrate oversubscription;
+- disconnect/reconnect and stale-session replay;
+- clock offset and drift between Muninn and Sleipnir hosts.
+
+Acceptance should bound p50/p95/p99 capture-to-HID age, lost/duplicated edges,
+time-to-neutral, glass-to-glass video age, audio discontinuities, A/V skew, and
+recovery time. Final-state-only tests will politely conceal the corpse.
+
+## What not to copy
+
+- Do not copy Moonlight's C implementation or protocol packets into GameCult
+  code without an explicit GPLv3 licensing decision. Architectural study is not
+  license laundering. See [Moonlight's license](https://github.com/moonlight-stream/moonlight-common-c/blob/82e25148549d249a80aaf4afc68e2abb07072edf/LICENSE.txt).
+- Do not replace typed CultMesh discovery, command state, or ownership with
+  RTSP/SDP or a Moonlight compatibility stack.
+- Do not make ENet the new universal answer. Moonlight's strength comes from
+  semantic queues above the carrier, not from the carrier's brand name.
+- Do not merge input, audio, and video into one ordered reliable stream. One
+  lost video fragment must not head-of-line block a button release or audio
+  packet.
+- Do not treat FEC as magic. Parity is useful only when its overhead and recovery
+  time fit the deadline.
+
+## Distilled doctrine
+
+Realtime strength is not “reliable UDP.” It is knowing which truth survives
+loss:
+
+- the newest state replaces old state;
+- an edge remains until applied or explicitly superseded;
+- a media packet is valuable only while its frame or playout deadline is alive;
+- predictive video damage is healed by recovery or a new reference, not by
+  delivering every corpse;
+- queues are latency budgets made physical;
+- feedback that cannot change sender behavior is telemetry, not control.
+
+Muninn and Sleipnir already have enough organs to become strong. The next work
+is to give each signal one explicit survival law and make the transport obey it.
+
+## 2026-07-17 LAN field results
+
+The Moonlight-derived ownership changes now have Raven-to-Starfire field
+evidence over LAN, with Raven processes launched only through hidden scheduled
+tasks:
+
+- Muninn video uses independently recoverable block parity plus bounded repair.
+  During a seeded 1% datagram-loss run, the OBS receiver advanced from 2 to 12
+  video assembly expiries while forwarding 14,400 additional payload groups:
+  99.93% completed without expiry. Audio reported zero failures, skips, or stale
+  packets in the same interval. The impairment proxy forwarded 2,147,356 of
+  2,169,105 datagrams with zero queue overflow.
+- Sleipnir latest-state delivery remained live through seeded 1% loss. Cutting
+  the proxy caused the non-neutral virtual Xbox pad to neutralize after 1.56 s,
+  owned by the named stale-input lease; restoring the hidden proxy reconnected
+  and resumed state without operator action.
+- A continuous 64-packet receive drain was retaining the newest input for about
+  48-57 ms before HID application. Bounding that drain to 2 ms reduced live
+  receiver-owned receive-to-apply time to typically 69-204 microseconds. A
+  witnessed 16 ms spike remains to characterize.
+- Starfire and Raven wall clocks differ by roughly 2.38 s. Sleipnir no longer
+  publishes their raw subtraction as one-way latency. Its surface reports that
+  source-clock latency is unavailable without a clock model and exposes only
+  monotonic receiver-owned stage durations.
+
+These results clear the initial 99.9% media-completion and disconnect-safety
+gates at 1% independent loss. They do not yet prove glass-to-glass latency,
+A/V skew, ordered quick-tap delivery under loss, 5%/burst behavior, or a long
+mixed-impairment soak. Those remain acceptance gates, not footnotes.
+
+The field comparison also exposed a generic transport invariant Moonlight's
+long-running sessions force us to respect: bounded wire identifiers must wrap
+deliberately. CultNet's fragmented-message ID previously saturated at the
+maximum `u16`, so fragmented audio became unreassemblable after the boundary.
+Wrap-to-one plus a boundary test removed the repeatable minute-eight collapse;
+a subsequent 10-minute direct LAN run remained clean across the boundary.
+
+## 2026-07-17 ordered-input closure
+
+The quick-tap gate exposed four authorities that generic RUDP reliability had
+blurred together:
+
+- A Windows sleep requested at two milliseconds could still miss a short tap.
+  Muninn now observes XInput on a dedicated high-resolution worker; transport,
+  discovery, serialization, and logging cannot delay capture.
+- Global cumulative ACKs could not retire a reliable packet arriving more than
+  32 realtime sequence numbers late, and reliable duplicates were not ACKed
+  after application deduplication. CultNet now directly acknowledges the late
+  packet and acknowledges reliable duplicates. This collapsed a runaway field
+  trace from hundreds of thousands of resend datagrams to a bounded flow.
+- Muninn used semantic application ACK as permission to send the next edge.
+  One delayed ACK therefore serialized the entire controller. It now sends a
+  bounded window of captured edges; CultNet owns retransmission, Sleipnir's
+  epoch/sequence cursor owns ordering, and semantic ACK only retires history.
+- Sleipnir published CultMesh/Eve and Idunn state synchronously on the actuator
+  thread. Those writes produced 0.7-1.8 second visible button holds. A bounded
+  coalescing publisher worker now owns control-plane projection, leaving the
+  input thread to receive, order, actuate, and acknowledge.
+
+The resulting first-hot-plug field proof generated 100 taps with a 16 ms source
+press and 84 ms gap. Under seeded 1% independent loss, every layer observed
+exactly 100 presses and 100 releases; Raven-visible durations were 24-57 ms.
+Under eight consecutive dropped packets every 200 datagrams, every layer again
+observed exactly 100 presses and 100 releases; visible durations were 24-40 ms,
+the final virtual pad was neutral, and the impairment proxy reported no queue
+overflow. Raven ran through hidden scheduled tasks over `192.168.1.0/24`; no
+WireGuard route participated. Both daemons used the Eve/Aetheria/VoidBot
+experimental CultLib lineage pinned at `8965f3c0`.
+
+This closes ordered digital edges at one 60 Hz source frame. It does not prove
+sub-frame synthetic ViGEm pulses: eight-millisecond state-only pulses can fall
+between XInput snapshots, and `XInputGetKeystroke` was rejected after it emitted
+stale events from a reused user slot. Analog motion under a sender stall,
+mixed media/input endurance, glass-to-glass video age, and A/V skew remain open.

+
+## Field acceptance matrix
+
+Run the real capture body, production receiver plugin, decoder, audio output,
+and Sleipnir virtual input through the seeded profiles under
+`E:\Projects\Odin\tests\realtime-impairment`. Observe the rendered/audio/input
+timeline, not only proxy CSV counters.
+
+| Profile | Required result |
+|---|---|
+| clean, 10 minutes | no decoder reset, audio discontinuity, input edge loss, queue growth, or timestamp drift; video p99 delivery under 50 ms |
+| iid 1%, 10 minutes | no input edge loss; audio FEC recovers eligible holes; at least 99.9% video frames presented; media p99 under 80 ms |
+| iid 3%, 5 minutes | bounded degradation; at least 99% video frames presented; decoder recovery within 250 ms; no stuck controls |
+| burst 4 and burst 8 | parity/repair handles eligible damage; unrecoverable dependency loss produces one requested IDR and recovery within 250 ms |
+| reorder and duplicate | no duplicate input action, stale state regression, or unbounded assembly/reorder storage |
+| delay/jitter | AIMD reduces bitrate before sustained deadline loss and recovers no faster than one step per two stable seconds |
+| stall 250 ms | obsolete media expires; queues remain bounded; input latest state converges within 35 ms after release |
+| reconnect | old input epoch cannot act; neutral/current state within 100 ms; decoded video within 500 ms |
+| mixed 60-minute soak | stable memory/handle/thread counts and no progressive A/V drift |
+
+The first seeded 1% proxy run is a failed acceptance result, not a pass: 987 of
+95,741 datagrams were dropped; in roughly one minute the receiver recorded 38
+expired video assemblies and 56 skipped audio packets while remaining bounded
+and avoiding decoder reset. CultNet fragmentation currently sits below
+application-level FEC, so one lost transport fragment discards an entire FEC
+shard. The next reliability cut is to make protected media shards fit one wire
+datagram or move fragmentation above the erasure-code boundary.
+
+## Field scars
+
+- A fragmented CultNet RUDP session failed repeatably after roughly eight to
+  nine minutes because the `u16` fragment-set ID used saturating increment and
+  became permanently stuck at 65,535. Every later fragmented audio document
+  then collided in one receiver reassembly key. The allocator now wraps from
+  65,535 to 1, with a boundary test. The clean field run above crossed that
+  boundary without a single audio reorder, skip, stale packet, or failure.
+- Audio and video producer ingress now use separate bounded channels. Video
+  capture can no longer block audio ingestion before the audio-priority send
+  scheduler sees it. Capacity-eviction counters proved zero during the clean
+  acceptance run.
+
+## 2026-07-17 bounded-media field cut
+
+The live path now keeps every protected shard in one datagram, sends AAC ADTS
+in fixed 864-byte 4+2 audio blocks, uses 768-byte video shards with 8+4 block
+FEC, and begins each decoder epoch at a complete IDR. The sender admits video
+to its repair cache when the frame enters the queue, accepts the production
+CultNet `realtime` channel, and can service bounded repair requests at
+64/96/128 ms in batches of up to eight chunks.
+
+Seeded Raven-to-Starfire evidence:
+
+- iid 1%: 802 of 78,406 datagrams dropped; zero decode drop, video expiry,
+  audio failure, or audio skip; 1,800 video frames recovered;
+- burst-4: 1,436 of 71,910 datagrams dropped; zero expiry or audio skip across
+  1,800 forwarded frames;
+- reorder: 2,872 reorder events; zero expiry or audio skip across 900 frames;
+- iid 3%: 2,564 of 85,731 datagrams dropped; three of 5,400 frames expired,
+  zero audio skip (99.94 percent video delivery);
+- burst-8: 190 chunks repaired; one of 1,800 frames expired, zero audio skip;
+- 250 ms stall: 420 datagrams withheld, one frame expired, 68 chunks repaired,
+  an IDR was requested, and another 900 frames arrived without a stuck decoder
+  or audio skip.
+
+Delay/jitter produced one expiry in 900 frames. Duplicate, reconnect, longer
+iid runs, and the 60-minute mixed soak remain open acceptance rows.
+
+Field scar: production video uses the `realtime` channel, but the repair cache
+previously admitted only legacy `media` payloads. Synthetic tests built the
+legacy shape and certified a repair path that was empty in production. The
+production-channel regression test now owns this boundary.
+
+## Completion rule
+
+Moonlight-level performance is reasonably expected only after all local rows
+remain green and the real field matrix passes twice: once on direct LAN and once
+on the deployed route actually used during streaming. Failure should change the
+owning deadline, FEC, encoder, or input authority—not add a repair loop around
+the symptom.

+## Move Tracking
+
+Starfire and Nightwing both have PS Move controllers directly attached over
+USB. Muninn represents what each local body can honestly observe:
+`muninn.move_marker_candidate.v1` for glowing orb candidates from cameras and
+`muninn.move_controller_state.v1` for controller/IMU/button/battery state from
+USB-attached Moves. Mimir drinks those feeds into `MimirStreamKind.Tracking`
+buffers, admits them into the native `move_evidence` reservoir view as
+compute-upload buffers, and publishes resolved `mimir.move_controller_pose.v1`
+documents for Fensalir interaction once calibration and fusion have earned a
+pose.
+
+Authority:
+
+- Starfire-local Move evidence is published by Muninn/Mimir local producers as
+  typed observation streams.
+- Nightwing Move evidence is emitted by Muninn on Nightwing over the typed
+  observation path.
+- Structured PS Move light pulses are Muninn output commands. Mimir requests
+  them by sending `muninn.move_light_command.v1` over CultNet/CultMesh to the
+  Muninn daemon on the host with the USB-attached Move; Mimir does not write
+  remote HID directly except through temporary smoke scripts used to prove
+  hardware behavior before Muninn is available on that host.
+- Odin discovers and projects the stream/schema surface for operator and agent
+  access.
+- Mimir owns subscription, rolling retention, native Move evidence buffer
+  layout, clock alignment, calibration, controller association, triangulation,
+  IMU fusion, prediction, and resolved wand pose publication. OBS and
+  dashboard summaries do not own this state.
+- Fensalir consumes Mimir's resolved Move controller poses as interactive input
+  for environments; it does not synthesize controller truth from raw Muninn
+  evidence.
+
+Smoke proof: `dotnet run --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj
+-- --move-tracking-contract-smoke` consumes one Starfire Move and one Nightwing
+Move observation into two tracking buffers.
+
+Calibration preflight proof: `dotnet run --project
+.\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj --
+--move-calibration-protocol-smoke --output
+artifacts\move-calibration\protocol.cc` writes
+`mimir.move_calibration_protocol.v1` for
+`mimir-move-calibration-starfire-nightwing-v1`. The protocol requires
+`muninn:starfire:move-evidence`, `muninn:nightwing:move-evidence`, and
+`mimir:starfire:move-controller-poses`; optionally drinks Quest headset and
+left/right controller poses over USB as an external VR reference; and requires
+Mimir to derive rig calibration, IMU calibration, controller identity mapping,
+and a calibration receipt before orientation can stop being
+`orientation:imu-unresolved`.
+
+Quest USB access belongs to Muninn, not Mimir. Starfire Muninn runs with
+`--quest-adb --quest-serial 1WMHHB68PG1515` and publishes
+`muninn.quest_access.v1`, including stream ids for Quest input, Quest poses, and
+warp-corrected video input from Brokkr/Unity. On 2026-06-12, `adb devices -l`
+reported authorized Quest 2 device `1WMHHB68PG1515` with product/device
+`hollywood`. This proves Starfire can query the headset over USB; it does not
+provide Quest headset/controller poses until a Quest/OpenXR witness bridge
+publishes those pose samples through Muninn.
+
+The old Nightwing bring-up path is archived:
+`scripts/start-nightwing-move-tracking.ps1`, `Mimir.EveSensorReceiver`,
+`Mimir.VerseRecorder`, and `nightwing_typed_witness_publisher.py` now fail
+closed. Runtime structured light commands belong to Muninn. Eye/Move
+observations must enter through typed CultMesh stream frames or
+Odin-discovered CultMesh documents; they are optical witness evidence for the
+later pose/fusion owner, not the final 6DoF pose authority.
+
+Starfire-local Move illumination smoke uses `scripts/start-starfire-move-light.ps1`.
+That launcher runs `Mimir.PsMoveProbe` against the local Windows HID col01
+output collection and refreshes the PS Move LED report for hardware proof when
+Muninn is not available on Starfire yet.
+
+Starfire should have Muninn for source-local Move HID control and local sensor
+publication. Some older Starfire audio/video paths still enter Mimir through
+local Mimir producers or diagnostic process bridges while direct native drivers
+mature. Same-host Move evidence and pose frames are CultMesh shared-memory byte
+rings. Remote media is different: the current Raven media body bridge uses
+CultNet/CultMesh documents over the mesh and lowers to local UDP for OBS
+compatibility, so it is not same-machine zero-copy into Mimir/Fensalir yet.
+
+Odin's Muninn organ owns the Move optical extraction stage for sensor stream
+exposure. Its Rust crate lives in `E:\Projects\Odin\crates\muninn-move-tracker`
+and publishes/feeds `muninn.move_marker_candidate.v1` records. Mimir consumes
+those Muninn candidate streams into tracking buffers; it does not own raw
+optical extraction. Mimir is now the explicit owner for stereo triangulation,
+camera calibration, controller association, IMU fusion, prediction, and final
+6DoF wand pose.
+Muninn's `muninn:nightwing:move-evidence:<sequence>` shared-memory frame now
+uses the canonical `muninn.move_marker_candidate.v1` document shape for optical
+markers instead of a placeholder empty slice. A daemon unit proves that a bright
+Y8 frame run through `muninn-move-tracker` serializes a non-empty marker
+candidate into the Mimir-compatible evidence frame. The daemon now has a
+source-local Y8 extraction/publish seam plus a first `serve` camera producer:
+`--move-marker-camera <camera-id>=<device-path>` polls a Unix V4L2 YUYV frame,
+converts it to compact Y8, and feeds that same seam. Nightwing hardware now
+runs as one Muninn provider with two private per-eye PSMoveAPI subprocesses.
+The parent alone owns lights, identity, commands, provider advertisement,
+persistence, and the aggregate evidence stream; children exchange hue state
+and camera-tagged observations over bounded MessagePack pipes.
+`muninn.move_tracker_health.v1` exposes each worker's camera backend,
+calibration, update/observation counters, RGB range, and expected-hue pixel
+evidence. Live exposure is 0.3 for `nightwing-eye-0` and 0.1 for
+`nightwing-eye-1`. Both eyes calibrate all four Moves and produce observations.
+Muninn's dedicated evidence aggregator now owns sequence and transport outside
+the 15-second CultCache telemetry loop. Cached controller state is bundled into
+fresh optical frames but cannot create frames by itself, and a deadline clock
+caps publication at the configured camera cadence. A 2026-07-13 Mimir field
+window received 622 unique frames in 15 seconds, 2,647 observations, and 1,384
+same-ID cross-camera correspondences while seeing all four stable Move IDs from
+both eyes. The same parent PID survived the run; transport health reported
+5,302 produced frames, 5,301 handoffs, 771 sends, and zero local-ring
+admissions. Full stereo calibration is still not implied: intrinsics and
+spatially diverse correspondences must earn the camera matrices.
+`MimirMoveStereoCalibrationAssessment` is the typed observability gate before
+any fit. It accepts only same aggregate-frame, same-Move correspondences and
+reports synchronized pair count, Move diversity, per-Eye 4x3 grid coverage,
+radius range, and missing physical inputs. The corrected live capture produced
+130 same-frame pairs with zero frame skew, but only 4/12 Eye 0 cells and 2/12
+Eye 1 cells; intrinsics and measured orb radius are also absent, so promotion is
+correctly false.
+`MimirMoveProofSurface` is the first Fensalir-visible proof surface for this
+chain. It consumes the Mimir admission receipt and the Mimir-owned pose stream
+frame, emits `mimir.move_proof_surface.v1`, and lowers an observer-only
+`AquariumSplineFrame` probe with the explicit
+`muninn:nightwing:move-evidence:<sequence> -> mimir:starfire:move-evidence:<sequence> -> mimir:starfire:move-pose:<sequence> -> fensalir:starfire:presented-frame:<sequence>`
+chain. It does not decide pose. Single-ray fallback remains a visible
+non-final verdict until calibrated multi-camera optical evidence earns full
+pose.
+`MimirMoveProofPipeline` is now the reusable commit primitive for that chain:
+from one Muninn CultMesh shared-memory frame it performs native admission,
+Mimir fusion, pose-frame creation, proof-surface creation, and Fensalir probe
+lowering. Live Nightwing/Starfire wiring should call this owner path rather
+than preserving separate manual actions and programmatic proof paths.
+`MimirRuntime` now owns the actual Fensalir presentation attachment for the
+proof surface: `PublishMoveProofSurface` stores the latest Mimir-owned
+`mimir.move_proof_surface.v1`, and `CreateFrame` merges its observer-only
+`move-proof-*` probe splines into `AquariumFrame.Scene.SplineFrame` beside the
+audio spectrum preview. Fensalir renders this frame; it still does not decide
+proof.
+`MimirMoveProofRuntimeDriver` is the runtime bridge from a Muninn CultMesh
+shared-memory evidence ring into that attachment point. It derives the
+Mimir evidence, Mimir pose, and Fensalir frame ids from the actual Muninn frame
+suffix, calls `MimirMoveProofPipeline`, suppresses duplicate frame admission,
+and lets `MimirRuntime.Update` publish the resulting proof surface. This proves
+the runtime-owned path for a ring frame; real Nightwing hardware and calibrated
+camera witnesses are still the missing field proof.
+`MimirMoveProofRuntimeConfiguration` is the typed selection and validation
+surface for that bridge. An enabled source must name the Muninn evidence stream,
+native reservoir path, Mimir evidence/pose frame prefixes, Fensalir
+presented-frame prefix, fusion authority, consumer contract, and at least two
+calibrated camera witnesses. It may create a runtime driver only when the
+supplied CultMesh ring stream id matches the configured evidence stream.
+`MimirRuntime` now owns activation for configured proof sources: on scene-ready
+it asks an `IMimirMoveProofEvidenceRingProvider` for the evidence ring, opens
+the configured native reservoir, registers the runtime driver, retains the
+driver resources, and exposes an activation status. The default provider fails
+explicitly because the current C# CultMesh ring is still in-process only;
+`Mimir.BufferSmoke --move-proof-runtime-activation-smoke` injects an in-process
+provider to prove the activation path without claiming live Nightwing field
+evidence.
+`mimir.move_proof_runtime_activation.v1` is the typed readiness/proof-spine
+surface for configured Move proof sources. It reports the configured evidence
+stream, provider kind, active/driver state, native reservoir path, calibrated
+camera ids, latest same-stream proof ids, latest verdict, and the inactive
+diagnostic when the default runtime lacks a live cross-process CultMesh ring
+opener. `Mimir.BufferSmoke --move-proof-runtime-activation-surface-smoke`
+proves both the active injected-ring document and the unavailable default
+document; this is readiness/proof observation, not field evidence.
+`mimir.move_proof_evidence_frame_snapshot.v1` is a one-copy, explicitly
+non-final fallback for captured Muninn evidence frames while C# CultMesh lacks
+a cross-process shared-memory opener. When `EvidenceSnapshotPath` is
+configured, `MimirConfiguredMoveProofEvidenceRingProvider` validates snapshot
+metadata against the encoded Muninn frame payload, publishes the payload into
+an owned in-process ring, and then delegates to the same runtime proof driver
+and pipeline. `Mimir.BufferSmoke --move-proof-runtime-snapshot-smoke` proves
+the same named proof spine through that file boundary. This can support field
+capture/replay, but live proof still requires the real Nightwing/Starfire ring
+or CultMesh page producer.
+Odin/Muninn can now write that artifact from the producer side with
+`--move-evidence-snapshot <path>`. The snapshot is written by the same Muninn
+Move evidence publisher that owns controller/marker frames, after the frame
+payload is accepted by the stream ring. Its unit coverage decodes the
+`mimir.move_proof_evidence_frame_snapshot.v1` tuple and re-decodes the embedded
+Muninn payload, proving the artifact is shaped for Mimir's snapshot provider.
+This is still one-copy field capture/replay; it does not replace the live ring
+or a CultCache page body producer.
+`MimirMoveProofDevSurface` is a dev-only bootstrap gated by
+`MIMIR_MOVE_PROOF_DEV_SURFACE`. It publishes a synthetic calibrated proof
+surface through the same `MimirRuntime.PublishMoveProofSurface` attachment so
+`Mimir.BufferSmoke --move-proof-presented-frame-smoke` can run `Mimir.App`
+headless, capture the actual Fensalir-presented PNG, and pixel-check that the
+named proof probe is visible. This is a renderer/probe proof, not live hardware
+evidence.
+
+## Program Composition
+
+[[docs/mimir-program-composition|Mimir Program Composition]] is the live
+authority map for stream-program output. Muninn runs on Starfire, Nightwing, and
+Raven-class capture hosts to publish local stream capabilities and selected
+media bodies. Mimir consumes only the streams it needs for calibration and
+composition, commits one typed scene graph,
+and publishes program output locally plus through a Yggdrasil-facing site
+publisher.
+
+The first typed program contracts live in `src/Mimir.Runtime/Synchronization`:
+
+- `mimir.program_scene.v1`
+- `mimir.program_output.v1`
+- `mimir.eve_operator_surface.v1`
+
+OBS scene JSON is import/mirror evidence for the initial crop/key/transform
+layout. It is not the editor of record after Mimir owns the scene graph.
+The current imported local scene state lives at
+`state/mimir-program-composition.cc`.

+`cultmesh://asgard.yggdrasil.mimir/media/raven-primary-av` route discovered
+through Odin/CultMesh. Starfire lowers the subscribed stream to local UDP for
+compatibility sinks because OBS is not a CultMesh runtime.
+
+Source audit correction resolved: `Mimir.CultMeshMedia` now uses explicit
+CultLib RUDP helpers for the sender/receiver and a relay-owned RUDP
+socket/session loop for multi-peer forwarding. The older
+`CultMesh.StartNodeAsync` and `CultMesh.ConnectClient` path no longer owns this
+media lane. The relay still persists received puts to CultCache as evidence and
+for inspection; live network transit is the RUDP schema-document path.
+
+Current deployment: Yggdrasil runs the relay from
+`/opt/gamecult/mimir-cultmesh-media/Mimir.CultMeshMedia` with cache
+`/var/lib/gamecult/mimir/cultmesh-media.cc` and log
+`/var/log/gamecult/mimir-cultmesh-media.log`. Senders and receivers target
+`cultmesh://asgard.yggdrasil.mimir/media/raven-primary-av`; concrete RUDP
+bootstrap lives in the CultMesh resolver environment, not in daemon launch
+arguments. Starfire writes `raven-primary-av` to `udp://127.0.0.1:5200`. OBS
+source `Raven Monitor + Realtek` points at that local UDP endpoint.
+
+`scripts/start-raven-cultmesh-av-sender.ps1` is the Mimir-owned CultMesh bridge
+bootstrap for Raven media-body transit. It is not the actual Muninn OBS feed
+owner. The real Raven OBS/SRT feed owner is Odin's Muninn:
+`E:\Projects\Odin\scripts\activate-muninn-raven-av-srt.ps1` drives the
+existing `GameCult-Muninn-Activate` hidden task and `muninn.exe activate`
+body on Raven, and `scripts/start-raven-muninn-obs-feed.ps1` in this repo is
+the thin local wrapper for that actuator. Keep `-LocalBootstrap` on the
+CultMesh sender only as a staging/bootstrap edge when the separate body-bridge
+lane needs direct local proof.
+
+## Daemon Health And Idunn
+
+Odin owns the accepted Verse/service map. Idunn owns continuity after a daemon
+is known: boot recovery, crash recovery, deployment freshness, stale-health
+watching, restart/deploy intent, and operator escalation. Mimir does not run a
+private lifecycle supervisor for these surfaces.
+
+CultLib's current direction is RUDP everywhere for typed CultNet/CultMesh
+documents across runtimes. That means health, provider advertisements, command
+boundaries, transport profiles, and selected program/media document lanes should
+default to `cultnet.transport.rudp.v0`. Product/debug render surfaces are
+lowerings, debug tools, or migration debt; they must not own daemon truth once
+an RUDP contract exists.
+
+Mimir's current daemon-health publishers are local RUDP witnesses:
+
+
+Invariant: health publication is not ownership. The daemon reports what it can
+honestly observe about itself; Idunn decides keepalive action through the
+shared typed record path.
+
+Source audit cut: `Mimir.EveSensorReceiver`, `Mimir.VerseRecorder`, the
+Nightwing typed witness publisher, and `start-nightwing-move-tracking.ps1` are
+archived. The old Nightwing/EVE witness lane no longer opens a renderer/client
+subscription surface. Witness publication and recording must use typed
+CultMesh/CultNet documents or CultMesh stream frames discovered through Odin.
+The media-frame bridge is already on that side of the line.

+The 2026-07-14 live two-wand session at
+`artifacts/move-calibration/live-two-wand-20260714-004210.*` passed collection
+coverage with 1,168 admitted same-frame pairs. The new Mimir-owned sphere
+stereo fitter recovers synthetic 505/535 px focal lengths within 0.43 px and a
+34 cm baseline within 0.22 mm, with 0.34/0.63 px held-out median/P95 error.
+The live artifact remains rejected: after robust radius admission its consensus
+fits at 0.51/2.08 px, but only 53.8 percent of held-out pairs agree and Eye 1's
+focal estimate leaves the physical range. PSMoveAPI age is currently projected
+as marker confidence by Muninn, so fresh wrong-color matches arrive near 0.996
+confidence. Repair source-local observation quality/continuity and calibrate
+per-Eye blob-radius response before asking the operator for another sweep. Do
+not promote the nominal 22.5 mm diagnostic fit.
+
+Odin `d0eded6` is deployed on Nightwing as binary SHA-256
+`a604fedaf90b26a49db6594b16b8b3499e3aed540152c6fda9dd9dbe87d37d39`.
+Each Eye worker now rejects stale, sub-2 px, out-of-bounds, and discontinuous
+PSMoveAPI positions before aggregation; tracker health publishes rejection
+counters, and candidate score is explicitly uncalibrated `0.5` instead of age
+masquerading as confidence. A post-deploy 10-second Mimir window received 555
+frames, 2,246 observations, and 443 stereo pairs. Radius P01 rose from about
+0.707 px to 3.13/3.64 px and confidence P50 is now 0.5 on both Eyes. Eye 1 saw
+only two plausible stationary IDs, which is honest and means another sweep is
+needed after Mimir models per-Eye blob-radius response.
+
+The active priority is Nightwing Move calibration. One public Muninn observer
+owns two private Eye workers and one aggregate evidence stream. Odin commits
+`39c839a`, `a340c33`, `8aefd1c`, and `f82ca7a` give daemon health a persistent
+serviced RUDP session and move optical aggregation onto its own deadline-clocked
+loop. The 2026-07-13 receipt at
+`artifacts/move-calibration/muninn-clocked-aggregator.mpack` contains 622 frames,
+2,647 observations, and 1,384 cross-camera correspondences in 15 seconds, with
+all four Move IDs visible to both Eyes. Next collect spatially diverse samples,
+calibrate intrinsics/extrinsics, and publish residual-bearing typed calibration.
