## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-03 (score 78, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-01 (score 77)

First indexed and scored.

## MCP tools (4)

### `validate_instance` (~108 tokens)

Validate an XML instance against its SDC4 XSD schema. Returns pass or fail with error counts.

Input parameters:

- `instance_path` (string, required): Path to the XML instance (Governed Data Record) to validate.
- `reference_path` (string): Optional path to a local copy of the SDC4 reference model (sdc4.xsd). Without it the model's include is fetched from its URL.
- `schema_path` (string, required): Path to the SDC4 data model XSD file.

### `validate_and_report` (~122 tokens)

Validate an XML instance and report every error: its path, its tier (structural or semantic), the constraint that failed, and the ExceptionalValue code recovery would use.

Input parameters:

- `instance_path` (string, required): Path to the XML instance (Governed Data Record) to validate.
- `reference_path` (string): Optional path to a local copy of the SDC4 reference model (sdc4.xsd). Without it the model's include is fetched from its URL.
- `schema_path` (string, required): Path to the SDC4 data model XSD file.

### `recover_instance` (~130 tokens)

Recover an XML instance: each value with a semantic error keeps its value and is tagged with an ISO 21090 ExceptionalValue. Returns the recovered record and each value covered; a record with structural errors is rejected.

Input parameters:

- `instance_path` (string, required): Path to the XML instance (Governed Data Record) to validate.
- `reference_path` (string): Optional path to a local copy of the SDC4 reference model (sdc4.xsd). Without it the model's include is fetched from its URL.
- `schema_path` (string, required): Path to the SDC4 data model XSD file.

### `check_schema_compliance` (~55 tokens)

Check whether an XSD schema follows SDC4 principles (restriction only, no xsd:extension). Does not validate instances.

Input parameters:

- `schema_path` (string, required): Path to the SDC4 data model XSD file.
