The Golden Claim

Case file

WC-26-118402 · a Halo EV loses power in Glenelg, and the trail leads to a battery lot 2,100 km away

A dealer submits a routine-looking BMS claim. Fourteen agents work it over forty-three days — across the customer, the dealer, Aurora and a battery supplier — while a warranty manager signs three decisions and reads everything else after the fact. The claim itself resolves in a week. What it unlocks takes six more.

The chain

Intake → Evidence → Entitlement → Diagnosis → Parts & labour → Adjudication → Payment → Attribution → Recovery → Dispute → Reconciliation → Pattern detection → Accrual → Audit

Fourteen stages. Eleven run without a person touching them. Three need a signature because policy says a person, not a model, carries the authority — every time, not on a sample.

Claims Intake Agent

Day 47 · 18 May, 09:14

Reads the claim exactly as the dealer submitted it. Nothing here is a decision yet.

✓Received from the dealer portal · Glenelg Aurora · RO D142-58230 · submitted 2 days after repair

✓VIN 6AUHA3E9SA402911 decoded · Halo EV · built October 2025 · 8 months in service · 42,900 km

✓Extracted: BMS module ×1 ($1,620.00), HV connector kit ×1 ($48.60), 2.1 h labour · claim total $1,979.40

✓Attachments: 4 photos, technician report, diagnostic scan export · completeness check passed

✓Duplicate check CTRL-WA-02 (VIN + code + 60 days): no match

Classified: Safety-adjacent · EV powertrain · matches an open lot pattern (CB-0417)

Evidence Collection Agent

Day 47–49 · 18–20 May

A BMS fault is safety-coded, so the evidence bar is higher than a normal parts claim — and this claim doesn't clear it yet.

✓Checklist for safety-coded BMS claims: diagnostic scan, technician report, photos, thermal event log, returned-part tag · 5 required

!Thermal event log MISSING · 4 of 5 items present · auto-request sent to Glenelg Aurora

✓Day 49 — dealer uploads the thermal event export from the vehicle's last service session

✓All 5 items now present and legible · CTRL-WA-04 evidence-completeness check passed

Warranty Entitlement Agent

Day 49 · 20 May

Is this vehicle, this owner, this component actually covered — before anyone spends time on what's wrong with it.

✓Asset and owner confirmed: single owner since sale, no transfer, no prior claims on this VIN

✓Policy EV-8 applies to the HV battery and drive unit: 96 months or 160,000 km, whichever first

✓8 months of 96 · 42,900 km of 160,000 · well within both

✓Exclusions checked: no modification codes, full service history, genuine parts only · none triggered

Verdict: COVERED under EV-8 · high confidence

Technical Diagnosis Agent

Day 49 · 20 May

Reads the fault code and the thermal log the way a senior technician would, and checks whether the story holds together.

✓P0A1F · cell-group 3 voltage divergence exceeding the safe delta · no thermal event above the abuse threshold

✓No external damage, no evidence of impact or improper charging in the telemetry

!Known-issues check: 60 prior claims this quarter with the identical fault code and signature, all on Halo EV built Oct 2025 – Jan 2026

✓Proposed repair (BMS module replacement + reflash) is technically consistent with the fault · no contradicting bulletin

Root-cause candidate: Cell-balancing circuit defect, likely originating upstream of the vehicle — flagged to Supplier Attribution

Parts & Labour Validation Agent

Day 49 · 20 May

Checks the bill of the repair against the bill of the vehicle, not against what the dealer typed.

✓BMS module part number matches the Halo EV configuration for this build window · no active supersession

✓Quantity 1, claimed $1,620.00 · matches the OEM reimbursement schedule exactly

!HV connector kit not normally required for this fault code · held for technician clarification

✓Clarification returned: connector corroded from the same failure event · line item approved, $48.60

✓Labour: 2.1 h claimed vs 2.1 h standard time for BMS R&R and reflash · exact match, no adjustment · CTRL-WA-05

Claim Adjudication Agent

Day 50 · 21 May

Combines everything above into one number and a rationale a stranger could follow — then, because the fault is safety-coded, stops short of paying it itself.

✓Entitlement: covered · Diagnosis: technically sound, lot-linked · Evidence: complete · Parts/labour: validated

✓Recommends APPROVE $1,979.40 in full · no adjustment on any line

!Safety code P0A1F · CTRL-WA-08 requires a person to sign every safety-related claim, regardless of amount

Human · Warranty Manager

Agent recommendation: Approve $1,979.40 in full. Entitlement, diagnosis and cost are all clean — the only reason this claim is here is the safety code.

✓ Approved in full · signed A. Novak, Warranty Manager (demo) · 21 May 2026 09:41

Payment Agent

Day 51–54 · 22–25 May

Turns an approval into money moving, and checks the money is going to the right place.

✓Dealer banking details for Glenelg Aurora verified against the last-confirmed record · no change-of-bank flag

✓Payment instruction WP-2026-0521 created for $1,979.40 · reconciled exactly against the approved amount

✓Settled 25 May, on Aurora's standard 3-business-day dealer payment run

Supplier Attribution Agent

Day 51 · 22 May

Follows the part backward from the vehicle to the factory floor that made it.

✓Returned-part serial traced: part BMS-HL-2025 · supplier Corvus Battery Systems · plant Corvus Adelaide Cell Assembly

✓Manufacturing lot CB-0417 · production window Oct 2025 – Jan 2026 · failure mode matches 60 prior claims on this lot

✓Claim rate on CB-0417 now 2.4% vs a 0.3% baseline, first crossed the 12-claim detection threshold on Day 16

Contractual basis: Supply agreement clause 6.4 · safety-related lot defect · full cost plus handling recoverable
Confidence: High · component serial traced to the lot, failure mode matches the cluster

Supplier Recovery Agent

Day 52 · 23 May

Prices the chargeback and sends it — this is routine, until it isn't.

✓Recoverable: $1,620.00 part + $310.80 labour + 10% handling = $2,123.88 · connector kit excluded, outside clause scope

✓Evidence package assembled: thermal log, diagnosis report, teardown request, CB-0417 cluster analysis, clause 6.4 text

✓Recovery claim SR-CB0417-061 sent to Corvus Battery Systems, 23 May

Supplier Dispute Agent

Day 58–60 · 29–31 May

Corvus doesn't just reject one claim — they reject the classification the other 60 claims depend on.

✕29 May — Corvus rejects: asserts the failure is "post-sale physical damage to the connector," disputes clause 6.4 entirely

!Stakes are higher than this claim: a rejected classification would jeopardize recovery on all 60 other CB-0417 claims raised so far

✓Pulls the independent bench-test report ordered at teardown: corrosion pattern consistent with an electrical fault causing localized heat — not the reverse

✓Cross-references the cluster: identical fault code and signature across 60 claims, 8× the baseline rate

!Rebuttal drafted, citing clause 6.4 and the cluster evidence · CTRL-WA-07 · escalated for sign-off before sending, because the dispute now covers the whole lot's classification, not one claim

Human · Supplier Relations Manager

Agent recommendation: Send the rebuttal, hold firm on clause 6.4. The bench-test report and the 60-claim cluster both point the same way; Corvus's damage theory doesn't explain the pattern.

✓ Rebuttal authorized and sent · signed R. Fontaine, Supplier Relations (demo) · 31 May 2026 14:02

Recovery Reconciliation Agent

Day 73–74 · 13–14 June

Watches for the money to actually arrive, and notices what changes when it does.

✓13 June — Corvus accepts clause 6.4 on the strength of the rebuttal · agrees to the full lot classification, not just this claim

✓14 June — credit memo CM-88213 received for $2,123.88 · matched exactly against the open receivable · closed

✓All other CB-0417 receivables, previously held as "pending classification," auto-transition to recoverable · 60 claims queued for batch invoicing

What this one claim unlocked: Recovery on the remaining CB-0417 lot, not previously collectible while the classification was disputed

Portfolio Pattern Detection Agent

Day 74–75 · 14–15 June

Now that the supplier has agreed the defect is real, the question changes from "who pays" to "is this bigger than a warranty problem."

✓CB-0417 now at 61 of an eventual 95 claims, 2.4% vs 0.3% baseline · rate exceeds 3× baseline over the 12-claim window by a wide margin

!Failure is safety-coded and supplier-confirmed · this is no longer treated as case-by-case warranty and recovery

✓Recommends referral to Product Safety and Engineering for a formal recall assessment, with the full CB-0417 evidence set attached

Human · Product Safety Liaison

Agent recommendation: Refer CB-0417 to Product Safety. Confirmed defect, safety code, rate 8× baseline and rising — this decision doesn't belong to warranty operations alone.

✓ Referred to Product Safety · signed D. Okafor, Product Safety Liaison (demo) · 15 June 2026 10:20

Warranty Accrual Agent

Quarter-end · 30 June

Folds this one claim, and the pattern behind it, into the number the auditor tests.

✓Claim cost booked to the Q4 FY26 provision at the time of payment, 25 May

✓Recovery of $2,123.88, and the queued recovery on the rest of CB-0417, reduces net exposure once received

!Recall referral flagged as a watch item for next quarter's accrual rate review · potential program cost exceeds simple per-claim warranty cost if a formal recall is declared

✓Recommends holding the accrual rate at 2.6% this quarter, pending the Product Safety assessment

Audit Agent

Ongoing · quarter-end sample

Rebuilds exactly why every decision above was made, in the order it was made, for someone who wasn't there.

✓Full evidence trail held from Day 47 intake to Day 74 recovery settlement to Day 75 referral · nothing overwritten, only appended

✓Safety-coded, supplier-disputed and recall-adjacent · included in the quarterly control-test population by rule, not by random sample

✓Segregation of duties confirmed: the agent that adjudicated the claim is not the person who approved payment, and is not the person who signed the rebuttal · CTRL-WA-09

✓Evidence pack #a41c9be2 assembled: policy EV-8, thermal log, bench-test report, cluster analysis, three signatures, all timestamped

What one claim proved

The case that unlocked the lot

$1,979.40Paid to the customer, touchless from the dealer's point of view — approved within 3 days of complete evidence

$2,123.88Recovered from Corvus on this claim alone, after a dispute that could have written it off entirely

60 claimsRecovery on the rest of lot CB-0417, unlocked the moment this claim's rebuttal was accepted

3 signaturesEvery other decision — eleven of fourteen stages — ran without a person, with the reasoning kept for the one time someone asks

This is the same lot CB-0417 that appears in the quarter-scale demo as "95 claims, agreed" — that status became true because of the dispute worked through here. One golden claim, not thirty-five disconnected demos: the eight agents that actually touched this case did real, different, visible work, and the audit trail reads as one story, not fourteen screenshots.
