## Findings

- **warn** Annotations that disagree with the tool in `prepare_energy_label_preflight_receipt` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "prepare_energy_label_preflight_receipt" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "prepare_energy_label_preflight_receipt" says "label": a word for a change.
```


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `prepare_energy_label_preflight_receipt`

- The name "prepare_energy_label_preflight_receipt" says "label": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Bundle the preflight lookups into one idempotent Ed25519-signed receipt committing to the FINGERPRINTED inputs, record references, sources, freshness and decision states — provable evidence of WHAT was looked up and WHEN. Attests the lookups, never a registration, conformity or market-access outcome. Preflight evidence only — never a conformity, CE, GPSR, safety or market-access determination.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `compare_eprel_product_metrics`

- The name "compare_eprel_product_metrics" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two or more COMPATIBLE records on their COMMON supplier-declared metrics — a value table only. Cross-product-group comparison fails safely as 'incompatible_comparison'; no 'best product', no ranking, no buying advice. Answers come from the queried source at the stated retrieval time: the official EPREL Public API in live mode, or a clearly-labelled synthetic fixture in dev/test — provenance.sourceAuthority names which. Supplier-declared data only; Jithox verifies nothing.
```

### `get_eprel_energy_label_data`

- The name "get_eprel_energy_label_data" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Structure the supplier-DECLARED energy-label / product-sheet data for one public record. The result states supplierDeclared=true and independentlyVerifiedByJithox=false explicitly — nothing is independently verified. Answers come from the queried source at the stated retrieval time: the official EPREL Public API in live mode, or a clearly-labelled synthetic fixture in dev/test — provenance.sourceAuthority names which. Preflight evidence only — never a conformity, CE, GPSR, safety or market-access determination.
```

### `get_eprel_product_record`

- The name "get_eprel_product_record" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Structure ONE public record by its public record identifier: declared supplier/brand, product group, declared public fields, documents, missing fields, provenance and freshness. 'exact_public_record' / 'no_match_in_queried_source' / 'unavailable'. Answers come from the queried source at the stated retrieval time: the official EPREL Public API in live mode, or a clearly-labelled synthetic fixture in dev/test — provenance.sourceAuthority names which. Supplier-declared data only; Jithox verifies nothing. Preflight evidence only — never a conformity, CE, GPSR, safety or market-access determination.
```

### `search_eprel_products`

- The name "search_eprel_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the queried source by model identifier, registration number, or supplier/brand + product group. Returns CANDIDATE public records with deterministic match kinds and visible ambiguity: 'exact_public_record' / 'possible_match' / 'multiple_matches' / 'no_match_in_queried_source' — a no-match is never 'not registered'. Outage → 'unavailable'; unverified schema → 'source_schema_unverified'; stale → 'stale'. Answers come from the queried source at the stated retrieval time: the official EPREL Public API in live mode, or a clearly-labelled synthetic fixture in dev/test — provenance.sourceAuthority names which. Supplier-declared data only; Jithox verifies nothing. Preflight evidence only — never a conformity, CE, GPSR, safety or market-access determination.
```
