Provenance
Every unit arrives with a record of what was checked.
What that record contains, where it is kept, and what has to be true of a unit before it can be written at all.
The tag
Every unit that reaches the catalogue carries a tag. The tag is issued at the end of testing, not at the start, and it records what was found rather than what was expected.
- Tag
- EXGX, the year, and the unit’s serial — one tag, issued once, never reused.
- Model
- The unit model, as verified against the purchase record.
- Grade
- A, B, C or F — one grade, assigned from the recorded results.
- Test date
- The date the unit completed testing.
- Hours burned in
- How long it ran under sustained load.
- Operator
- The initials of the person who ran it.
- Destruction certificate
- The certificate number for the certified data destruction, where the unit held data.
The registry, and what it gates
Every issued tag is entered in the unit registry. A unit is not eligible to be listed until its tag is issued and entered — so a listing is not a claim that a unit will pass, it is a record that it already did.
The tag's contents appear verbatim in the listing. A buyer reading a listing is reading the tag. No listing states a grade, a benchmark result, or a warranty status that the tag does not support.
Before Exigenix buys it
Exigenix asks every counterparty the same three questions, together, in one message, before any other assessment. A party that holds the hardware, or genuinely acts for the holder, answers all three in one reply without consulting anyone — these are facts they already have.
- What it is
- Exact part number and quantity, with serial numbers available on request.
- Where it is
- Where the units are physically located now, and who has custody of them.
- Whose it is
- Whether the counterparty owns the units or represents the owner — and if they represent the owner, what written authority they hold from that owner.
A counterparty who cannot answer all three does not become an approved supplier. Partial answers are recorded as partial: Exigenix does not complete a counterparty's answer on their behalf, and does not treat a confident manner as a substitute for a fact.
When it arrives
- Photographed
- Every unit is photographed before it is unboxed — packaging condition first, then the unit itself — before any handling that could be disputed later.
- Logged
- Serial numbers, configuration and condition as received, recorded against the purchase record it arrived under.
- Quarantined
- A received unit does not enter the sales pipeline, is not listed, and is not represented to any buyer as available until it has cleared all nine gates. Nothing is pre-graded or pre-priced ahead of the result.
If a unit's condition, configuration or serial does not match the purchase record — or a lock or entitlement flag turns up that the seller did not disclose — a dispute is opened before the unit goes any further, documented with the receiving photographs and the purchase record. A unit under dispute is held separately, is never represented as available, and if nothing is resolved it is not accepted into inventory at all.
What has to be true before a unit is graded
Grading is the eighth of nine gates. Two of the earlier ones ask about the unit's identity and its history rather than its performance, and a unit that fails either does not receive a grade by default — it is re-run, or it is graded F.
- Identity
- Model and serial number are confirmed against the purchase or lot listing, and the firmware version is confirmed.
- Control
- The unit is checked for vendor lock, fleet-management and ownership-transfer flags that would stop Exigenix or a buyer taking full control of it. Any unresolved lock flag is a gate failure — a unit Exigenix cannot fully control is not graded and not listed.
- Resident data
- Certified data destruction is completed on any storage, and on any accelerator or system with resident state, before the unit is graded. It is a precondition of intake completing rather than an option, and the certificate number is recorded on the tag.
What a figure on a tag is, and is not
Benchmarks are run with a named, publicly available, vendor-neutral suite appropriate to the unit — and the result is recorded against the published reference for that exact model.
It is stated as a result recorded against that reference. It is not stated as an absolute figure Exigenix guarantees a buyer will reproduce, in their own power, cooling, firmware and workload. No benchmark result is estimated, and a unit that cannot complete the suite has failed a gate rather than earned an approximate number.
What happens to a unit that does not pass
A unit graded F is parts or recycle only. It is never sold as working, whatever partial functionality it retains, and it never reaches the catalogue.
A, B and C are listed, and each one says on its own tag what it is: A passes every gate at full specification, B passes with the derating noted, C is functional and sold as-is with the faults disclosed.
