Repair Obligation & Spare-Parts AI Agent
Measure each part order against the window Reg. (EU) 2023/1670 owed on the day it arrived, five working days and later ten, and leave the price and the impossibility call to a named person.

What this agent does
Measures the window, never the price
In
- 01
A part is ordered, and the window runs from receipt, inside a seven-year period counted from end of placement.
- 02
A part is ordered in year six, and ten working days is owed; the first five years of that period owed five.
Reason
- 03
A part is ordered by an end-user, and Reg. (EU) 2023/1670 sends only some part classes that far.
- 04
A passport is demanded in a tender, and no Digital Product Passport obligation binds an electronics product today.
- 05
Placement of the last unit ends, and operating-system and security updates are owed free for at least five years.
Decide
- 06
A source-code release lands, and a security update is owed in four months, a functionality update in six.
- 07
An order lands on a chain with no EU manufacturer, and Art. 5(3) walks the duty down to the seller.
Out
- 08
A repair information form is voluntary under Art. 4(1); once given, its price holds thirty calendar days.
- 09
Execute write actions only inside the approval boundaries agreed during implementation.
Product statement
The agent holds the availability file and measures delivery against the owed window; a named person decides a repair is impossible, approves the price and signs the declaration.
Example workflow
One order, receipt to close
- 1Part order receivedEnd-user request, professional repairer order or a service-network draw
- 2Availability file matchedModel, end-of-placement date, part class, audience and the window owed on the day of receipt
- 3Window recordedFive or ten working days, with the registration and access windows a professional repairer is owed
- 4Controls appliedClock checks, part-class checks, cascade checks and completeness confidence
No human action required
Stages 1 to 4 run unaided, and nothing is promised or priced at any of them — the agent is measuring, and the compliance lane opens at the completeness gate.
Goes to the product compliance lead to close.
Adds a regulatory counsel read first.
Product compliance review
The file is held with its clocks, its part classes and its gaps.
Close the order · Append evidence · Send to counsel
Closed — by a named person
- 6Parts and service records updatedOnly where write access and disclosure policy allow it
- 7Outcome evaluatedWindow margin, evidence completeness, counsel corrections and what a later review found
Corrections
Each counsel correction is counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Deciding that a repair is impossible.
- Approving a repair price, or any part of one.
- Issuing or standing behind a repair information form.
- Declaring a model conformant in EPREL.
Automation boundary
Agent acts unaided
- ✓Hold one availability file for each model and for each part class.
- ✓Run the owed window from receipt of the order.
- ✓Measure each actual delivery against the working-day window owed.
- ✓Flag the day the five-day window turns into ten.
Nothing is promised or priced except by a named person, inside the agreed boundaries.
- Judging which party the Art. 5(3) cascade lands on.
- Telling a customer a part class is out of scope.
- Setting an operating-system support end date.
- Changes to window rules, part classes or file fields.
Example output
One order, annotated
Directive (EU) 2024/1799 applied on 31 July 2026, and this file is what a person closes the order from.
Availability file · single order
Illustrative example- Order
- Display assembly, slate tablet
- Owed as
- Display assembly to an end-user, year six of seven
- Clock
- Day 7 of ten working days
- Window of record

- Held for
- The product compliance lead, in person
As received
Taken from the availability file and the order receipt — Art. 5 reaches only the Annex II product groups.
What the file holds
- The order receipt
- End-of-placement date
- Part class and audience
Why no price call here
A reasonable price is the Art. 5(2) test, and the Annex I form carries no signature block.
What the score decides
Below the configured threshold the file picks up a counsel read before.

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 order
From the parts system
Statutory window, not service level
Warranty triage and field service own commercial repair; this is the window the rule owed, and take-back sits with our EEE producer agent.
The clock changes gear
Five working days for the first five years of the availability period, ten for the remaining two — Reg. (EU) 2023/1670, applying from 20 June 2025.
Where the score and the seal live
The repairability class sits in energy-labelling Reg. (EU) 2023/1669, and an EPREL verification taken without a trade-register code expires 22 April 2027.
Build an evidence trail
The part, the window it was owed in and the person who approved the repair stay on the record.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.
Parts and service systems
- ERP parts master
- spares
- Service-network order feeds
Product and lifecycle records
- PLM
- model masters
- End-of-placement records
Registration and labelling
- EPREL model registrations
- Repairer registration portal
Agent
Repair obligation & parts
- Reads the order
- Measures the window
- Holds for the lead
Repair and case systems
- Service tickets
- RMA
- Repairer access requests
Observability & evaluation
- OpenTelemetry
- Langfuse
- Supported monitoring/evaluation sources
Integration availability depends on the client's existing systems and API access.
Agent controls
Six layers between the model and the file
Six layers, tightening inward. Whatever reaches the centre is described in the map below.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether a file may stand
- L3
- Puts the close in a person's hands
- L4 – L5
- Keep the order and the window behind it
- L6
- Holds the order at unpromised when signals degrade
How Nestack evaluates it
Evaluate the whole assembly — not only the file that comes out.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the file an authority reads
- E1Final-output evaluationDid the file record the window the rule owed that day?
- E2Step-level evaluationDid the agent use the right part class, the right audience and the current clock?
- E3Tool evaluationDid it read and write the correct order and the correct model record?
- E4Confidence calibrationDo low-confidence files actually attract more counsel corrections?
- E5Slice evaluationHow does performance change across specific model lines?
- E6Business outcomeHow many files needed a correction before the lead closed them?
Floor — the outcome the manufacturer answers for
Failure modes
Where each failure originates in the agent
Seven failure modes, set where each one first enters the availability file.

- IJ-07
Silent window regression
A rule change moves the window without moving the file.
Stage tracks
Model, prompt, window rules and part classes
- Sev-1 · an order is promised without a person
- Sev-2 · a wrong window reaches the file
- Sev-3 · source degrades, file holds unclosed
Affected slices
One model line absorbs the corrections
A model-level window-adherence figure can read clean while a single model line absorbs most of the corrections. Nestack reports the counsel-correction rate by model, not only in total.
Slice performance — reported separately, not only in aggregate

Evidence-linked improvement
What an unreconstructable file costs
A cycle closes when the missed delivery window is a regression case. That suite is what the next order measured is judged against.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Counsel-correction rate rises in one model line.
- 02
Diagnose
The part promised in five days by a clock that had already moved to ten is read back until one cause remains.
- 03
Improve
Changes go out numbered, and the models that drove them ride along.
- 04
Verify
One model case still failing keeps the release where it is.
- 05
Learn
It joins the suite for good, and the window rules move in the same commit.
Learn → Detect
The return edge. The next order is measured against a suite one case longer.
Typical build scope
Twelve workstreams across six weeks

Next step · Electronics AI agent
Build a repair-obligation agent around a clock that changes gear mid-life.
Germany adopted its Reparaturgesetz on 26 June 2026, and the EUR-Lex implementing-measures list could not be read, so we publish no count of Member States that finished. Next step: send us one model file, and we will measure last month's orders against the window each was owed.
