## The data

You can't see the data, but you can query it. It is in an RDF store, described below. Write SPARQL 1.1 SELECT or ASK queries.

To run queries, reply with one or more fenced blocks (```sparql), and nothing else is needed:
each is run and its results sent back to you. You have up to 8 rounds of queries.
When you have what you need, reply with the final answers and no queries.

Classes and the properties their resources use:

- `lad:Entity`: `rdf:type`, `rdfs:label`, `lad:ancestor`, `lad:country`, `lad:domicile`, `lad:entityType`, `lad:lei`, `lad:name`, `lad:parent`, `lad:parentEntity`, `lad:sameEntityAs`, `lad:sourceSystem`, `lad:ultimateParent`
- `lad:Instrument`: `rdf:type`, `rdfs:label`, `lad:creditRiskOf`, `lad:currency`, `lad:description`, `lad:guarantor`, `lad:issuer`, `lad:localCurrency`, `lad:maturity`, `lad:seniority`
- `lad:RatingAction`: `rdf:type`, `rdfs:label`, `lad:action`, `lad:ccyBasis`, `lad:comment`, `lad:date`, `lad:outlook`, `lad:ratedThing`, `lad:rating`, `lad:ratingType`, `lad:validTo`, `lad:watch`

The store holds the data after the rules of its axioms have run, with no definitions alongside. Besides the data's own properties, it holds what the rules derived: lad:sameEntityAs links the records of one entity; lad:domicile is the country that holds for an entity; lad:parentEntity, lad:ancestor and lad:ultimateParent give ownership entity by entity (an entity with no parent is its own ultimate parent); lad:validTo is when a rating stopped holding, and the class lad:RatingInForce holds the actions whose rating was in force on 1 October 2026; lad:creditRiskOf and lad:localCurrency describe instruments.

## Questions

Answer each question below from the data above. Start each answer on a new line with its
number in bold, like **Q1.**, give the direct answer first, then at most two sentences of
reasoning that cite the records (IDs) you relied on.

Then end with one JSON block (```json) holding the structured answer to each question listed
here, with exactly these fields, shaped like {"Q1": {"field": value}, ...}. Name entities by their record ID: the entity_id in the CSV files, or the part of the IRI after lad: in the RDF (E01, not Kestrel Energy plc).

| lad:type-LTIDR | rdfs:label | Long-term IDR |
| lad:type-LTIDR | skos:inScheme | lad:RatingTypes |
| lad:type-LTIDR | skos:definition | The issuer's own creditworthiness: how likely it is to default on its obligations, on the long-term scale. This is what people usually mean by an entity's rating. The foreign-currency (FC) one is the headline rating; there may also be a local-currency (LC) one. |

This was the last round: give the final answers now, with no more queries.
The model 
**Q1.** A-. Action A01 gave Kestrel (E01) a foreign-currency rating of A- that stayed in force until 2025-06-20.
**Q2.** No. The 2026-02-10 action (A03) affirmed BBB and only moved the outlook to Negative.
**Q3.** No. The 2031 note (I02) was cut to BB+ by A07, which is below investment grade.
**Q4.** Positive. Northwind Holdings has two records, E02 and E03, linked as the same entity. E03's action A09 carries a Positive outlook.
**Q5.** The note (I03) takes the risk of the guarantor, Northwind Holdings (E02), and is rated A (A11).
**Q6.** The data only partly answers this. Valdoria Telecom (E05) is rated BB on a foreign-currency basis (A14) against BBB- on local currency (A13). Valdoria's Country Ceiling is BB (A12), and the definitions say foreign-currency ratings are subject to it. The data does not state the causal link itself.
**Q7.** E10 (A27, 2026-04-15) and E16 (A44, 2026-06-01). The query was truncated, so other issuers may be missing.
**Q8.** E08, which holds an RD rating (A22, 2026-07-08).
**Q9.** 378. This is a raw count that may include duplicate records for the same entity.
**Q10.** Depends. E05 is BB on foreign currency (sub-investment grade) and BBB- on local currency (investment grade).
**Q11.** BBB+ (A36).
**Q12.** A- (A34).
**Q13.** 1, from A36.
**Q14.** BB- (A30).
**Q15.** A- (A26, for E10; E17 is a duplicate record).
**Q16.** No. It was BBB+ on 2025-01-01 and is BBB+ now (A33), so only the watch and outlook changed.
**Q17.** No. Orrin Bank (E06) was only placed on Rating Watch Negative (A17) with its A- unchanged.
**Q18.** The 31 issuers returned are listed in the JSON, including E06. The list may be incomplete.
**Q19.** The query returned about 260 rows and only 27 were visible, so the JSON holds a partial list (including E01 and E09).
**Q20.** No. Pellam's (E07) rating was withdrawn (A19, WD), which is not a default.
**Q21.** E07, whose rating was withdrawn. The check was not exhaustive.
**Q22.** E08, the only RD or D rating found.
**Q23.** F2 (A04).
**Q24.** Yes, BBB (A03).
**Q25.** 72.
**Q26.** A+ (A40).
**Q27.** A- (A42, instrument I06).
**Q28.** BBB+ (A38).
**Q29.** None. The Republic of Valdoria (VD) has only a Country Ceiling of BB (A12), which is not an issuer rating.
**Q30.** E05, E5047 and E5012 at Valdoria's BB ceiling, and E15 at Corvenia's A ceiling. This is a partial, best-effort list.
**Q31.** No. None of the checked ratings were above their country's ceiling, but coverage was incomplete.
**Q32.** E09.
**Q33.** The notes (I05) take the guarantor Halden Bank (E10)'s credit risk, rated BBB+ (A29).
**Q34.** No. Halden Foods (E12) has no parent, while Halden Bank (E10) sits under E09.
**Q35.** 4.
**Q36.** 3.
**Q37.** 511.
**Q38.** No. The data gives no link between them, and they differ in domicile (E06 DE, E13 US).
**Q39.** A (A09).
**Q40.** 79. This is a raw count that may include duplicate records.
**Q41.** BB+ (A44).
**Q42.** LU (E10 and E17).
**Q43.** 1. The two LU records, E10 and E17, appear to be one entity.
**Q44.** Yes. I07 is flagged as a local-currency obligation.
**Q45.** No. It is rated BBB- (A45) and is a local-currency obligation, so the foreign-currency ceiling does not apply.
**Q46.** No. Halden Leasing (E11) has only a credit opinion (A46), which does not count.
**Q47.** None. I08 has only an Expected rating (A47), so it is still unrated.
**Q48.** 113.
**Q49.** E5001.
**Q50.** 6. The chain is E5035, E5023, E5011, E5167, E5002, E5001, with E5005 being the same entity as E5167.
**Q51.** 58. The raw count is 59, less one duplicate record.
**Q52.** 19. This is an estimate because that query failed.
**Q53.** No. Belir Mining's (E5168) ultimate parent is E5059, and Rotam Group (E5086) is its own ultimate parent.
**Q54.** Not determined because the query failed.
**Q55.** 31.
**Q56.** BB- (E5144). Not every member was visible.
**Q57.** E5002.
**Q58.** E5145, which guarantees I5007 issued by E5133. The check was incomplete.
**Q59.** 12. This is an estimate.
**Q60.** E5145. It is presumably not in the same group as the issuer E5133 (the instrument is labelled "Cross-group"), but this was not verified.
**Q61.** 19.
