What this agent does
Raises the excursion, never the verdict
In
- 01
Where readings come from — trailer, chamber and probe telemetry, or a carrier's own logger export.
- 02
When units or labels differ by asset, normalised, each reading kept with the sensor it came from.
Reason
- 03
Where a reading sits against the limits in the customer's own plan, not against a vendor default.
- 04
When an excursion opens, the lot, lane and shipment it touches are identified and attached.
- 05
Where the record has gaps, silence is marked as a gap rather than read as a lane with no event.
Decide
- 06
When a probe drifts, stalls or disagrees with its neighbours, the sensor itself is flagged.
- 07
Where a lot is affected, it defaults to hold and routes to the named qualified person.
Out
- 08
When the file closes, the readings, the excursion, the basis and the disposition are retained.
- 09
Where writes are configured, they run only inside the boundaries agreed at implementation.
Product statement
The agent watches and evidences; a named qualified person dispositions the lot, and the shipper, carrier and receiver each keep their own duty.
Example workflow
One excursion, reading to disposition
- 1Readings receivedTrailer, chamber and probe telemetry, or a carrier's own logger export
- 2Context assembledLimits, lot, lane, sensor health and the readings either side of it
- 3Excursion raisedReadings, duration, lots affected, confidence
- 4Controls appliedReading checks against the plan's own limits, sensor-health checks, hold-by-default and confidence threshold
No human action required
Stages 1 to 4 run unaided, and nothing is released at any of them — the lot is held, and the qualified person's lane opens at the confidence gate.
Goes to the qualified person to disposition.
Adds a sensor-integrity read first.
Qualified-person disposition
The lot is held with its readings, the sensor's health and the confidence.
Disposition · Hold · Send to quality review
Dispositioned — the lot may move
- 6Quality and warehouse systems updatedOnly where write access and approval policy allow it
- 7Outcome evaluatedDisposition outcomes, false excursions, sensor faults found and findings raised after delivery
Dispositions
Every disposition a person made is counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Releasing a lot that is being held for review.
- Declaring that a food is or is not adulterated.
- Closing an excursion without a qualified person.
- Deciding whether the affected product may be sold.
Automation boundary
Agent acts unaided
- ✓Watch the readings against the limits the plan already sets for the named owner.
- ✓Raise an excursion and default the affected lot to hold.
- ✓Assemble the readings, the gaps and the sensor's own health.
- ✓Carry the whole file to the named person who decides it.
Any write happens inside the boundaries agreed at implementation, and never to a controller.
- Writing a setpoint to a refrigeration controller.
- Specifying the operating temperature for a load.
- Assessing at the dock whether abuse was significant.
- Changes to limits, hold rules or release authority.
Example output
One excursion, annotated
Everything the agent raises is attached to the readings it was drawn from.
Excursion output · single lot
Illustrative example- Lot
- Chilled lane, one pallet
- What was observed
- Trailer air ran above the plan's limit during a multi-stop drop
- Time above limit
- 42 minutes
- Limit on the plan
- Set by the customer's plan
- Confidence
- 89%
- Sensor health
- Probe last calibrated, in range
As received
Taken from the trailer telemetry and the customer's own limits — nothing on this side is written by the agent.
Source records used
- Trailer telemetry
- Probe calibration
- Shipper's written spec
Why it stops here
The reading is a fact; whether the food is adulterated is a conclusion the law.
What the score decides
Below the configured threshold the lot picks up a sensor-integrity read first.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Every reading
From the lane's own sensors
Watch against the plan
Draw on the readings, the customer's own limits and the probe's calibration history — monitoring indicates a condition, and the refrigeration is what maintains it.
An excursion is not a verdict
Routine lanes run watched, logged and evidenced without anyone reading a chart.
Send the qualified person to the holds
If a lot moved and a problem surfaced after delivery, the trail shows the readings, the sensor's health, and who released it on what basis.
Build an evidence trail
The excursion, the readings behind it and the qualified person who dispositioned it stay with the lot.
Integrations

Integration availability depends on the client's existing systems and API access.
Agent controls
Six layers between the model and the lot
Every control encloses the next. What survives the set is named in the map below.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether a lot may move
- L3
- Puts the disposition in a qualified person's hands
- L4 – L5
- Hold the readings the excursion rests on
- L6
- Falls back to raw temperature reporting when signals degrade
How Nestack evaluates it
Evaluate the monitoring workflow — not only the excursion that alarmed.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the excursion quality reads
- E1Final-output evaluationDid every raised excursion match the readings behind it?
- E2Step-level evaluationDid the agent use the right limits, lot and sensor history?
- E3Tool evaluationDid it read and write the correct lot and the correct lane?
- E4Confidence calibrationDo low-confidence excursions actually attract more sensor faults?
- E5Slice evaluationHow does performance change across specific lane types?
- E6Business outcomeHow many lots needed a re-disposition, or a finding after delivery?
Floor — the lot the firm answers for
Failure modes
Where each failure originates in the agent
Seven ways an excursion goes wrong, placed by stage.
Agent lifecycle
Direction of processing →
01 · Retrieval
1 mode
- BR-03
Degraded sensor trusted
A drifting probe is read as though it were in calibration.
Stage gathers
Readings, limits, lot and lane, and probe calibration
02 · Reasoning
2 modes
- BR-04
Excursion read as verdict
A reading outside a limit is written up as adulterated product.
- BR-06
Duty put on one party
One party is named responsible where the rule splits the duty.
Stage proposes
Excursion, readings, lots affected and confidence
03 · Tool / write
2 modes
- BR-02
Held lot moved
A held lot moves on before a person dispositioned it.
- BR-05
Duplicate excursion
One temperature event is raised twice against the same lot.
Stage writes
Only where write access and approval policy allow it
04 · Output
1 mode
- BR-01
Excursion never raised
A gap in the readings passes as a lane with no event.
Stage returns
The excursion a qualified person dispositions
05 · Change / Version
1 mode
- BR-07
Silent threshold drift
A model or limit change widens what the agent will pass.
Stage tracks
Model, prompt, limit sets and lane configuration
- Sev-1 · a held lot moved
- Sev-2 · an excursion was never raised
- Sev-3 · sensor degrades, lot routes to review
Affected slices
One lane can carry the whole excursion rate
The under-counted slice is the probe that drifts rather than fails: it never alarms, so its lots never reach the excursion total at all. Nestack reports the re-disposition rate by slice, not only in total.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Sensors drifting, not failing | 9.7% | 3.4× | Review | |
| Multi-stop delivery lanes | 6.6% | 2.3× | Review | |
| Loading and dock transfers | 4.6% | 1.6× | Watch | |
| Single-leg refrigerated lanes | 2.0% | 0.7× | Normal |
Bar: re-disposition-rate lift vs. single-leg-lane baseline · scale 0–4.0× · tick marks the 2.0× review threshold
2 of 4 slices over threshold
Evidence-linked improvement
Every cycle ends in a standing case
The loop closes on a case the next release must pass, not on an explanation. That suite is what the next excursion raised on a lot is measured against.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Re-disposition rate rises in a lane slice.
- 02
Diagnose
Which lane, which asset, which probe? The readings and the excursions raised off them are read until the cause narrows to one.
- 03
Improve
The fix is versioned with the excursions that motivated it.
- 04
Verify
Nothing ships while an affected case is failing.
- 05
Learn
The case is added for good, and the disposition rules change.
Learn → Detect
The return edge. The next excursion meets a suite one case longer.

W6One shipping season monitored under quality, then handover
- Reading the band
- The bars follow real work rather than a plan, which is why week 5 carries two kinds rather than padding.
- At the end of W6
- The season closes validation and Agent Care assumes monitoring.
- Duration
- Six-week plan shown · typical delivery 4–6 weeks depending on scope confirmed in discovery.
Next step · Food & Beverage AI agent
Build a cold-chain agent that holds the lot and hands you the file.
Show us a lane, its sensors and your limit sets. Who releases a held lot at two in the morning, and on what basis — the shipper who set the operating temperature, the carrier who must demonstrate it, or the receiver at the dock? We build the boundary around that answer.
