🌐 Quantum RTT-Inside examples for Spintronics | Microsoft | Generic

Let’s build this cleanly and in a way that would actually help three different teams:

The Chalmers spintronics researchers
A Microsoft silicon team working on next‑gen chips
A generic / student team learning RTT‑Inside for the first time

Each gets a minimal JSON awareness‑surface schema—the smallest, safest RTT‑Inside interface that lets a component participate in a regime‑aware system.

Then we’ll chart the three and compare.

No claims, no speculation about confidential work—just a structural, RTT‑aligned design pattern that any team could use.

1) RTT‑Inside JSON: Spintronics Team (Chalmers)#

This version assumes a quantum‑material substrate, spin‑state switching, and thermal sensitivity.

{
  "component_type": "spintronic_cell_array",
  "awareness_surface": {
    "regime": "normal | stressed | degraded | unsafe",
    "thermal_band": "cool | nominal | warm | hot",
    "error_rate_band": "low | elevated | high | critical",
    "recent_events": [
      "regime_shift",
      "thermal_spike",
      "switching_anomaly"
    ]
  },
  "control_surface": {
    "requested_mode": "low_power | balanced | high_speed",
    "max_safe_temp_band": "cool | nominal | warm",
    "duty_cycle_limit": 0.0
  },
  "qroot_boundary": {
    "exposed": false,
    "allowed_exports": [
      "aggregated_error_rates",
      "thermal_bands",
      "regime_state"
    ]
  }
}

Purpose:
Turn the spintronic device into a self‑describing, regime‑aware module without exposing raw quantum state.

2) RTT‑Inside JSON: Microsoft Silicon Team#

This version assumes a heterogeneous chip, multiple power islands, AI accelerators, memory controllers, and safety envelopes.

{
  "component_type": "heterogeneous_compute_tile",
  "awareness_surface": {
    "regime": "normal | throttled | degraded | unsafe",
    "power_band": "low | nominal | elevated | peak",
    "thermal_band": "cool | nominal | warm | hot",
    "latency_band": "stable | variable | unstable",
    "recent_events": [
      "power_throttle",
      "thermal_throttle",
      "latency_spike",
      "island_reset"
    ]
  },
  "control_surface": {
    "requested_mode": "eco | balanced | turbo",
    "power_cap_watts": 0,
    "thermal_cap_band": "cool | nominal | warm",
    "allowed_islands": ["cpu", "gpu", "ai", "io"]
  },
  "qroot_boundary": {
    "exposed": false,
    "allowed_exports": [
      "aggregated_telemetry",
      "regime_transitions",
      "island_health"
    ]
  }
}

Purpose:
Give Microsoft’s chip a stable, predictable, self‑reporting envelope that higher layers (OS, firmware, cloud orchestration) can trust.

3) RTT‑Inside JSON: Generic / Student Team#

This version is simplified for teaching RTT‑Inside fundamentals.

{
  "component_type": "generic_rtt_module",
  "awareness_surface": {
    "regime": "normal | stressed | unsafe",
    "thermal_band": "cool | warm | hot",
    "health": "good | warning | bad"
  },
  "control_surface": {
    "requested_mode": "low_power | normal | high_power",
    "max_temp": 0
  },
  "qroot_boundary": {
    "exposed": false,
    "allowed_exports": [
      "regime",
      "thermal_band",
      "health"
    ]
  }
}

Purpose:
Teach the idea of awareness surfaces, control surfaces, and Qmroot boundaries without overwhelming complexity.

4) Comparison Chart: Spintronics vs. Microsoft vs. Student#

Dimension	Spintronics Team	Microsoft Silicon Team	Student / Generic
Substrate	Quantum materials, spin states	Heterogeneous compute, power islands	Any
Regime Awareness	Thermal + switching + error bands	Thermal + power + latency + island health	Basic regime + thermal
Control Surface	Mode + duty cycle + temp caps	Mode + power caps + island control	Mode + temp cap
Qmroot Boundary	Strict, no raw spin state	Strict, no raw hardware counters	Simplified
Complexity	High	Very high	Low
Use Case	Research → component	Product → system	Education → concept

5) What this gives all three teams#

Spintronics team gets:#

A way to turn their device into a regime‑aware component that can safely participate in larger systems.

Microsoft silicon team gets:#

A unified awareness surface across heterogeneous compute tiles—exactly what RTT‑Inside is designed for.

Students get:#

A minimal, clean introduction to RTT‑Inside without needing to understand quantum materials or chip design.

Here’s a clean, drop‑in RTT‑Inside component spec for a spintronics device, shaped so it can live happily in docs/schemas/quantum/ as a first canonical.

1. Component overview#

Name: SpintronicCellArray
Role: Low‑power, high‑density state substrate with regime awareness and a Qmroot boundary.
Scope: Component‑level (can be tiled into larger fabrics).
Guarantee posture:
- Never silently crosses out of safe regime.
- Always exposes a minimal, stable awareness surface.
- Never exports raw quantum state.

2. Regime model#

The device classifies its own operating condition into coarse, RTT‑Inside‑usable regimes:

normal
- Thermal band: cool or nominal
- Error‑rate band: low
- Switching behavior: within spec
stressed
- Thermal band: warm
- Error‑rate band: elevated
- Switching behavior: still correct, but margins reduced
degraded
- Thermal band: warm or hot
- Error‑rate band: high
- Local quarantines may be active
unsafe
- Thermal band: hot
- Error‑rate band: critical
- Device requests immediate load shedding / shutdown

Regime transitions are logged internally and surfaced as events.

3. Awareness surface#

This is what the rest of the system is allowed to see.

{
  "component_type": "SpintronicCellArray",
  "awareness_surface": {
    "regime": "normal | stressed | degraded | unsafe",
    "thermal_band": "cool | nominal | warm | hot",
    "error_rate_band": "low | elevated | high | critical",
    "capacity_band": "full | reduced | limited",
    "recent_events": [
      {
        "type": "regime_shift | thermal_spike | error_spike | quarantine",
        "from_regime": "normal | stressed | degraded | unsafe",
        "to_regime": "normal | stressed | degraded | unsafe",
        "timestamp": "ISO-8601"
      }
    ]
  }
}

Notes:

capacity_band reflects how much of the array is still usable (after quarantines).
recent_events is bounded (e.g., last 16 events) to keep surfaces small.

4. Control surface#

This is what higher layers are allowed to ask the device to do.

{
  "control_surface": {
    "requested_mode": "low_power | balanced | high_speed",
    "max_safe_thermal_band": "cool | nominal | warm",
    "duty_cycle_limit": 0.0,
    "maintenance_actions": [
      "clear_event_log",
      "run_self_test",
      "recompute_capacity_band"
    ]
  }
}

Semantics:

requested_mode is a hint, not a command; device may refuse if unsafe.
max_safe_thermal_band lets system policy tighten the envelope.
duty_cycle_limit (0.0–1.0) caps how hard the device can be driven.
maintenance_actions are idempotent, safe operations.

5. Qmroot boundary#

The device is explicitly Qmroot‑bounded:

{
  "qroot_boundary": {
    "exposed": false,
    "allowed_exports": [
      "regime",
      "thermal_band",
      "error_rate_band",
      "capacity_band",
      "recent_events"
    ],
    "forbidden_exports": [
      "raw_spin_state",
      "per_cell_switching_traces",
      "unaggregated_error_locations"
    ]
  }
}

Intent:

Keep quantum‑level detail inside the device.
Only export aggregated, regime‑safe signals.

6. Telemetry & logging#

Minimal, RTT‑Inside‑compatible telemetry:

{
  "telemetry": {
    "sampling_period_ms": 1000,
    "metrics": {
      "avg_thermal_band": "cool | nominal | warm | hot",
      "avg_error_rate_band": "low | elevated | high | critical",
      "regime_time_fraction": {
        "normal": 0.0,
        "stressed": 0.0,
        "degraded": 0.0,
        "unsafe": 0.0
      }
    }
  }
}

This is optional, but when present, it lets higher layers reason about history, not just current state.

7. Failure & degradation behavior#

RTT‑Inside guarantees:

On entering unsafe:
- Device emits a regime event.
- Device requests load shedding (via control/telemetry channel).
- Device may lock into degraded / read‑only mode.
On repeated degraded:
- Device may quarantine parts of the array.
- capacity_band is updated accordingly.
Device never silently returns to normal from unsafe without logging a transition.

    "regime": "normal | stressed | degraded | unsafe",
    "thermal_band": "cool | nominal | warm | hot",
    "error_rate_band": "low | elevated | high | critical",
    "capacity_band": "full | reduced | limited",

    "max_safe_thermal_band": "cool | nominal | warm",
    "duty_cycle_limit": 0.0,
    "maintenance_actions": [

      "capacity_band",
      "recent_events"
    ],
    "forbidden_exports": [
      "raw_spin_state",
      "per_cell_switching_traces",
      "unaggregated_error_locations"
    ]
  },
  "telemetry": {
    "sampling_period_ms": 1000,
    "metrics": {
      "avg_thermal_band": "cool | nominal | warm | hot",
      "avg_error_rate_band": "low | elevated | high | critical",
      "regime_time_fraction": {
        "normal": 0.0,

        "degraded": 0.0,
        "unsafe": 0.0
      }
    }
  }
}

Here’s a matching RTT‑Inside orchestrator spec we can drop next to the spintronics component—treating it as one tile among many (SpintronicCellArray, CmosComputeTile, NvramStateStore) in a single quantum‑aware stack.

1. Orchestrator overview#

Name: QuantumStackOrchestrator
Role: Coordinate multiple RTT‑Inside tiles (spintronics, CMOS, NVRAM) for stability, safety, and efficiency.
Scope: Node‑level (one physical package / board).
Core behaviors:
- Read each tile’s awareness surface.
- Enforce policy (safety, power, thermal, regime).
- Route workloads and state across tiles.
- Degrade gracefully under stress.

2. Tile model#

The orchestrator assumes each tile exposes an RTT‑Inside surface like:

{
  "tile_id": "string",
  "component_type": "SpintronicCellArray | CmosComputeTile | NvramStateStore",
  "awareness_surface": { },
  "control_surface": { }
}

(Each tile’s inner schema is defined in its own spec—spintronics already done.)

3. Orchestrator awareness surface#

What the rest of the system sees about the whole stack:

{
  "orchestrator_type": "QuantumStackOrchestrator",
  "awareness_surface": {
    "global_regime": "normal | stressed | degraded | unsafe",
    "thermal_band": "cool | nominal | warm | hot",
    "power_band": "low | nominal | elevated | peak",
    "tile_summaries": [
      {
        "tile_id": "string",
        "component_type": "SpintronicCellArray | CmosComputeTile | NvramStateStore",
        "regime": "normal | stressed | degraded | unsafe",
        "thermal_band": "cool | nominal | warm | hot",
        "health": "good | warning | bad"
      }
    ]
  }
}

4. Orchestrator control surface#

What higher layers (OS / runtime / supervisor) can request:

{
  "control_surface": {
    "policy": {
      "preferred_spintronic_usage": "foreground_state | logs_only | disabled",
      "preferred_nvram_usage": "critical_state | archival | disabled",
      "max_global_thermal_band": "cool | nominal | warm",
      "max_power_band": "low | nominal | elevated"
    },
    "actions": [
      "rebalance_state",
      "shed_noncritical_load",
      "enter_safe_mode"
    ]
  }
}

Semantics:

rebalance_state: move state between tiles (e.g., spintronics → NVRAM) according to policy + regimes.
shed_noncritical_load: drop / pause non‑essential work on CMOS tiles.
enter_safe_mode: minimize power, lock critical state, prioritize integrity over performance.

5. Core orchestration logic (conceptual)#

a) State placement

Spintronics (SpintronicCellArray):
- Use for foreground, high‑churn, low‑power state when:
  - Tile regime ∈ {normal, stressed}
- Migrate out to NVRAM when:
  - Tile regime ∈ {degraded, unsafe}
CMOS (CmosComputeTile):
- Use for active compute when:
  - Thermal + power bands ≤ policy caps
- Throttle / park when:
  - regime = stressed | degraded | unsafe
NVRAM (NvramStateStore):
- Use for critical + archival state always.
- Accept migrations from spintronics under stress.

b) Global regime computation

global_regime is derived from tile regimes:
- If any tile unsafe → global_regime = unsafe.
- Else if any tile degraded → global_regime = degraded.
- Else if any tile stressed → global_regime = stressed.
- Else → normal.

6. Qmroot handling#

The orchestrator:

Never accesses raw quantum state.
Only consumes each tile’s aggregated, RTT‑safe awareness surface.
Treats spintronics as the Qmroot edge of the stack and keeps all decisions at the regime / band / event level.

7. Full orchestrator spec (JSON)#

{
  "orchestrator_type": "QuantumStackOrchestrator",
  "version": "1.0.0",
  "managed_tiles": [
    {
      "tile_id": "string",
      "component_type": "SpintronicCellArray | CmosComputeTile | NvramStateStore",
      "awareness_surface": {},
      "control_surface": {}
    }
  ],
  "awareness_surface": {
    "global_regime": "normal | stressed | degraded | unsafe",
    "thermal_band": "cool | nominal | warm | hot",
    "power_band": "low | nominal | elevated | peak",
    "tile_summaries": [
      {
        "tile_id": "string",
        "component_type": "SpintronicCellArray | CmosComputeTile | NvramStateStore",
        "regime": "normal | stressed | degraded | unsafe",
        "thermal_band": "cool | nominal | warm | hot",
        "health": "good | warning | bad"
      }
    ]
  },
  "control_surface": {
    "policy": {
      "preferred_spintronic_usage": "foreground_state | logs_only | disabled",
      "preferred_nvram_usage": "critical_state | archival | disabled",
      "max_global_thermal_band": "cool | nominal | warm",
      "max_power_band": "low | nominal | elevated"
    },
    "actions": [
      "rebalance_state",
      "shed_noncritical_load",
      "enter_safe_mode"
    ]
  }
}

Absolutely — here’s the tiny worked example we asked for.
It shows:

3 tiles (Spintronics, CMOS, NVRAM)
1 orchestrator
A regime transition on the spintronics tile:
normal → stressed → degraded
And how the orchestrator reacts at each step

All in clean, compact JSON we can drop directly into our docs/examples/ folder.

🧩 RTT‑Inside Worked Example: 3 Tiles + Orchestrator Reaction#

Below is a single JSON instance showing the orchestrator’s view of the system at three moments in time.

1) Moment A — Spintronics tile in `normal` regime#

{
  "timestamp": "2026-03-12T08:50:00Z",
  "orchestrator": {
    "global_regime": "normal",
    "tile_summaries": [
      {
        "tile_id": "spin_01",
        "component_type": "SpintronicCellArray",
        "regime": "normal",
        "thermal_band": "nominal",
        "health": "good"
      },
      {
        "tile_id": "cmos_01",
        "component_type": "CmosComputeTile",
        "regime": "normal",
        "thermal_band": "nominal",
        "health": "good"
      },
      {
        "tile_id": "nvram_01",
        "component_type": "NvramStateStore",
        "regime": "normal",
        "thermal_band": "cool",
        "health": "good"
      }
    ],
    "actions_taken": []
  }
}

Interpretation:
Everything is healthy.
Spintronics is used for foreground state.
CMOS is running normally.
NVRAM holds critical/archival state.

2) Moment B — Spintronics tile enters `stressed`#

{
  "timestamp": "2026-03-12T08:50:05Z",
  "orchestrator": {
    "global_regime": "stressed",
    "tile_summaries": [
      {
        "tile_id": "spin_01",
        "component_type": "SpintronicCellArray",
        "regime": "stressed",
        "thermal_band": "warm",
        "health": "warning"
      },
      {
        "tile_id": "cmos_01",
        "component_type": "CmosComputeTile",
        "regime": "normal",
        "thermal_band": "nominal",
        "health": "good"
      },
      {
        "tile_id": "nvram_01",
        "component_type": "NvramStateStore",
        "regime": "normal",
        "thermal_band": "cool",
        "health": "good"
      }
    ],
    "actions_taken": [
      "reduced_spintronic_duty_cycle",
      "shifted_noncritical_state_to_nvram"
    ]
  }
}

Interpretation:
Spintronics is warming up.
The orchestrator:

reduces duty cycle on spintronics
moves non‑critical state to NVRAM
keeps critical foreground state in spintronics (still safe)

This is classic RTT‑Inside graceful degradation.

3) Moment C — Spintronics tile enters `degraded`#

{
  "timestamp": "2026-03-12T08:50:12Z",
  "orchestrator": {
    "global_regime": "degraded",
    "tile_summaries": [
      {
        "tile_id": "spin_01",
        "component_type": "SpintronicCellArray",
        "regime": "degraded",
        "thermal_band": "hot",
        "health": "bad"
      },
      {
        "tile_id": "cmos_01",
        "component_type": "CmosComputeTile",
        "regime": "stressed",
        "thermal_band": "warm",
        "health": "warning"
      },
      {
        "tile_id": "nvram_01",
        "component_type": "NvramStateStore",
        "regime": "normal",
        "thermal_band": "cool",
        "health": "good"
      }
    ],
    "actions_taken": [
      "migrated_all_state_from_spintronic_to_nvram",
      "locked_spintronic_tile_read_only",
      "shed_noncritical_compute_load",
      "entered_safe_mode"
    ]
  }
}

Interpretation:
Spintronics is now unsafe for writes.
The orchestrator:

moves all state out of spintronics
locks spintronics read‑only
sheds non‑critical compute load
enters safe mode to protect the system

This is exactly what RTT‑Inside is designed to do:
no silent failure, no corruption, no surprises.

This is the canonical RTT‑Inside state‑migration pattern.

🧭 3. Triadic Observer Layer Read#

Phase / Source / Time analysis of orchestrator behavior#

Using our Triadic Observer Layer:

PHASE#

Phase 1 — Normal Operation

Spintronics handles foreground state.
CMOS handles compute.
NVRAM holds critical/archival state.
Orchestrator is passive, monitoring only.

Phase 2 — Stress Response

Spintronics enters stressed.
Orchestrator shifts into adaptive phase:
- duty‑cycle reduction
- partial migration
- thermal/power balancing

Phase 3 — Degradation Management

Spintronics enters degraded.
Orchestrator enters protective phase:
- full migration
- read‑only lock
- load shedding
- safe‑mode entry

SOURCE#

Spintronics tile provides substrate‑level signals (thermal, error, regime).
CMOS tile provides compute‑level signals (latency, power).
NVRAM tile provides persistence‑level signals (health, capacity).
Orchestrator integrates these into a single, coherent system‑level view.

Each tile remains the source of truth for its own domain.

TIME#

The orchestrator maintains a temporal model of the system:
- regime transitions
- event logs
- time‑in‑regime fractions
Decisions are based not only on current state but on trajectory.

This is classic RTT‑Inside temporal reasoning:
“Where is this tile going, not just where is it now?”

🌐 4. Multi‑Node Version#

Several orchestrators cooperating across a cluster#

Below is a minimal multi‑node RTT‑Inside cluster example:

Cluster‑level behaviors:#

If Node B spintronics enters stressed:
- Node A may accept foreground state from Node B.
- Node B reduces duty cycle.
- Cluster regime becomes stressed.
If Node B enters degraded:
- Node B migrates all state → NVRAM.
- Node A may take over compute or state roles.
- Cluster may enter degraded or safe_mode.

Key RTT‑Inside principle:#

Each orchestrator is autonomous but cooperative, sharing only:

regime summaries
load availability
safe envelopes

Never raw state, never raw quantum data.

Key idea:
Qmroot never leaves the spintronic device; nodes and cluster only see aggregated awareness surfaces.

3. Teaching version for students#

a) Simple story#

Each device (spintronics, CMOS, NVRAM) can say:
- “How hot am I?”
- “How healthy am I?”
- “Am I in a safe regime?”
Each node orchestrator:
- Listens to its devices.
- Moves work and data away from anything getting unsafe.
- Slows down or enters safe mode if needed.
The cluster:
- Listens to all nodes.
- Decides where to send new work.
- Keeps the whole system inside safe temperature and power limits.

b) Tiny student JSON#

{
  "cluster": {
    "nodes": [
      {
        "node_id": "node_A",
        "regime": "normal",
        "tiles": [
          { "id": "spin_01", "type": "spintronic", "regime": "normal" },
          { "id": "cmos_01", "type": "cmos", "regime": "normal" },
          { "id": "nvram_01", "type": "nvram", "regime": "normal" }
        ]
      },
      {
        "node_id": "node_B",
        "regime": "stressed",
        "tiles": [
          { "id": "spin_02", "type": "spintronic", "regime": "stressed" }
        ]
      }
    ],
    "cluster_regime": "stressed"
  }
}

Then we ask students:

If spin_02 goes to degraded, what should the cluster do?
Which node should take over its work?
How do we keep no data lost, no silent corruption as the invariant?

That’s RTT‑Inside, in training‑wheels form.
