System Architecture
Single-machine deterministic architecture.
Single-machine, deterministic. Each stage emits bounded artifacts: replayable, verifiable, hashed. No sync threads, no alternate branches.
Execution model
Offline single-machine operations.
Single host
- Runs on one GPU-capable workstation.
- No distributed inference layer.
- All weights, prompts, and schemas live locally.
GPU-bound inference
- Workloads batch to saturate a single GPU.
- Scheduling: capture → chunk → inference → synthesis.
- No speculative execution or opportunistic sampling.
No external calls
- No network requests or remote APIs.
- Air-gapped capable by default.
- Approved export media must be mounted before sealing outputs.
Determinism & constraints
Constrained deterministic operation.
Fixed prompts
Versioned, hashed, tamper-aware. Prompt identity travels with every record.
Fixed schemas
Every artifact conforms to a predefined JSON structure. No freeform fields.
No freeform reasoning
The output layer is constrained extraction only. Open-ended generation has no pathway.
Evidence over speculation
Pattern matching against captured artifacts. Nothing is inferred beyond what was recorded.
Failure modes
Enumerated degradations.
Nothing is hidden. Each failure has a documented response and audit trail.
Video or audio loss
- Signal failure immediately flags the active block.
- Remaining modalities continue to capture with explicit NULL ranges.
- Synthesis script requires manual note describing the gap.
Model resource limits
- Chunk is retried with a smaller batch size.
- Persistent OOM marks the chunk as bypassed with a completeness flag.
- Synthesis consumes available evidence only.
Partial or invalid blocks
- Every block carries completeness metadata.
- Incomplete sequences still seal but display status and reason codes.
- No silent retries. Operators approve any regeneration.
Failsafe synthesis / replay
- Deterministic script can re-run synthesis from evidence blocks.
- Hashes are compared against previous runs before sealing.
- Any divergence is logged and requires operator approval.

Hardware
Purpose-built appliance.
The system runs on a compact, dedicated workstation with an integrated touchscreen. It is not a general-purpose PC. Camera inputs are routed directly into the unit. Setup is minimal by design.
Compact form factor
Small footprint designed to fit within an existing surgical suite without infrastructure changes.
Integrated display
Touchscreen interface for session control and status monitoring. No external peripherals required.
Dedicated architecture
All inference, storage, and processing run on a single purpose-built unit. No shared compute.
Offline architecture
Self-contained deployment.
All processing, inference, and storage occur on the local unit.
No cloud dependency at any stage of the pipeline.
Records remain under clinic control. They are never transmitted externally.
Updates arrive as signed media packages installed manually under operator control.
Air-gapped operation is the default. Network access is not required for any core function.
