Refactor ontology schema: Remove obsolete slot 'analyzes_or_analyzed', add new slots for 'accept', 'affect', 'aggregate_from', 'allocate', 'allow', and 'analyze'; introduce AttestationConfidenceEnum for lexical attestations; migrate annotations to structured slots; enhance documentation for clarity and usability.

- Removed obsolete slots: `has_or_had_custodian_observation`, `provider`, and `specificity_annotation`.
- Updated `has_or_had_score` slot to use `SpecificityScore` class and modified its description and examples.
- Added new slots: `end_seconds`, `end_time`, `has_archive_path`, `has_or_had_custodian_name`, `protocol_name`, and `protocol_version`.
- Introduced a script `check_annotation_types.py` to validate the presence and structure of `custodian_types` in YAML files.
- Added a script `update_specificity.py` to automate updates related to `SpecificityAnnotation` to `SpecificityScore`.

+# Exact Mapping Predicate/Class Distinction Rule
+
+🚨 **CRITICAL**: The `exact_mappings` property implies semantic equivalence. Equivalence can only exist between elements of the same ontological category.
+
+## The Rule
+
+1.  **Slots (Predicates)** MUST ONLY have `exact_mappings` to ontology **predicates** (properties).
+    *   ❌ INVALID: Slot `analyzes_or_analyzed` maps to `schema:object` (a Class).
+    *   ✅ VALID: Slot `analyzes_or_analyzed` maps to `crm:P129_is_about` (a Property).
+
+2.  **Classes (Entities)** MUST ONLY have `exact_mappings` to ontology **classes** (entities).
+    *   ❌ INVALID: Class `Person` maps to `foaf:name` (a Property).
+    *   ✅ VALID: Class `Person` maps to `foaf:Person` (a Class).
+
+## Rationale
+
+Mapping a slot (which defines a relationship or attribute) to a class (which defines a type of entity) is a category error. `schema:object` represents the *class* of objects, not the *relationship* of "having an object" or "analyzing an object".
+
+## Verification Checklist
+
+When adding or reviewing `exact_mappings`:
+- [ ] Is the LinkML element a Class or a Slot?
+- [ ] Does the target ontology term represent a Class (usually Capitalized) or a Property (usually lowercase)?
+- [ ] Do they match? (Class↔Class, Slot↔Property)
+- [ ] If the target ontology uses opaque IDs (like CIDOC-CRM `E55_Type`), verify the type definition in the ontology file.
+
+## Common Pitfalls to Fix
+
+- Mapping slots to `schema:Object` or `schema:Thing`.
+- Mapping slots to `skos:Concept`.
+- Mapping classes to `schema:name` or `dc:title`.

+# Rule: Generic Slots, Specific Classes
+
+**Identifier**: `generic-slots-specific-classes`
+**Severity**: **CRITICAL**
+
+## Core Principle
+
+**Slots MUST be generic predicates** that can be reused across multiple classes. **Classes MUST be specific** to provide context and constraints.
+
+**DO NOT** create class-specific slots when a generic predicate can be used.
+
+## Rationale
+
+1.  **Predicate Proliferation**: Creating bespoke slots for every class explodes the schema size (e.g., `has_museum_name`, `has_library_name`, `has_archive_name` instead of `has_name`).
+2.  **Interoperability**: Generic predicates (`has_name`, `has_identifier`, `has_part`) map cleanly to standard ontologies (Schema.org, Dublin Core, RiC-O).
+3.  **Querying**: It's easier to query "all entities with a name" than "all entities with museum_name OR library_name OR archive_name".
+4.  **Maintenance**: Updating one generic slot propagates to all classes.
+
+## Examples
+
+### ❌ Anti-Pattern: Class-Specific Slots
+
+```yaml
+# WRONG: Creating specific slots for each class
+slots:
+  has_museum_visitor_count:
+    range: integer
+  has_library_patron_count:
+    range: integer
+
+classes:
+  Museum:
+    slots:
+      - has_museum_visitor_count
+  Library:
+    slots:
+      - has_library_patron_count
+```
+
+### ✅ Correct Pattern: Generic Slot, Specific Class Usage
+
+```yaml
+# CORRECT: One generic slot reused
+slots:
+  has_or_had_quantity:
+    slot_uri: rico:hasOrHadQuantity
+    range: Quantity
+    multivalued: true
+
+classes:
+  Museum:
+    slots:
+      - has_or_had_quantity
+    slot_usage:
+      has_or_had_quantity:
+        description: The number of visitors to the museum.
+
+  Library:
+    slots:
+      - has_or_had_quantity
+    slot_usage:
+      has_or_had_quantity:
+        description: The number of registered patrons.
+```
+
+## Intermediate Class Pattern
+
+Making slots generic often requires introducing **Intermediate Classes** to hold structured data, rather than flattening attributes onto the parent class.
+
+### ❌ Anti-Pattern: Specific Flattened Slots
+
+```yaml
+# WRONG: Flattened specific attributes
+classes:
+  Museum:
+    slots:
+      - has_museum_budget_amount
+      - has_museum_budget_currency
+      - has_museum_budget_year
+```
+
+### ✅ Correct Pattern: Generic Slot + Intermediate Class
+
+```yaml
+# CORRECT: Generic slot pointing to structured class
+slots:
+  has_or_had_budget:
+    range: Budget
+    multivalued: true
+
+classes:
+  Museum:
+    slots:
+      - has_or_had_budget
+
+  Budget:
+    slots:
+      - has_or_had_amount
+      - has_or_had_currency
+      - has_or_had_year
+```
+
+## Specificity Levels
+
+| Level | Component | Example |
+|-------|-----------|---------|
+| **Generic** | **Slot (Predicate)** | `has_or_had_identifier` |
+| **Specific** | **Class (Subject/Object)** | `ISILCode` |
+| **Specific** | **Slot Usage (Context)** | "The ISIL code assigned to this library" |
+
+## Migration Guide
+
+If you encounter an overly specific slot:
+
+1.  **Identify the generic concept** (e.g., `has_museum_opening_hours` → `has_opening_hours`).
+2.  **Check if a generic slot exists** in `modules/slots/`.
+3.  **If yes**, use the generic slot and add `slot_usage` to the class.
+4.  **If no**, create the **generic** slot, not a specific one.
+
+## Naming Indicators
+
+**Reject slots containing:**
+*   Class names (e.g., `has_custodian_name` → `has_name`)
+*   Narrow types (e.g., `has_isbn_identifier` → `has_identifier`)
+*   Contextual specifics (e.g., `has_primary_email` → `has_email` + type/role)

+# Mapping Specificity Rule: Broad vs Narrow vs Exact Mappings
+
+## 🚨 CRITICAL: Mapping Semantics
+
+When mapping LinkML classes to external ontologies, you MUST distinguish between **equivalence**, **hypernyms** (broader concepts), and **hyponyms** (narrower concepts).
+
+### The Rule
+
+1.  **Exact Mappings (`skos:exactMatch`)**: Use ONLY when the external concept is **semantically equivalent** to your class.
+    *   *Example*: `hc:Person` `exact_mappings` `schema:Person`.
+
+2.  **Broad Mappings (`skos:broadMatch`)**: Use when the external concept is a **hypernym** (a broader, more general category) of your class.
+    *   *Example*: `hc:AcademicArchiveRecordSetType` `broad_mappings` `rico:RecordSetType`.
+    *   *Rationale*: An academic archive record set *is a* record set type, but `rico:RecordSetType` is broader.
+    *   *Common Hypernyms*: `skos:Concept`, `prov:Entity`, `schema:Thing`, `schema:Organization`, `rico:RecordSetType`.
+
+3.  **Narrow Mappings (`skos:narrowMatch`)**: Use when the external concept is a **hyponym** (a narrower, more specific category) of your class.
+    *   *Example*: `hc:Organization` `narrow_mappings` `hc:Library` (if mapping inversely).
+
+### Common Violations to Avoid
+
+❌ **WRONG**:
+```yaml
+AcademicArchiveRecordSetType:
+  exact_mappings:
+    - rico:RecordSetType  # WRONG: This implies AcademicArchiveRecordSetType == RecordSetType
+```
+
+✅ **CORRECT**:
+```yaml
+AcademicArchiveRecordSetType:
+  broad_mappings:
+    - rico:RecordSetType  # CORRECT: RecordSetType is broader
+```
+
+❌ **WRONG**:
+```yaml
+SocialMovement:
+  exact_mappings:
+    - schema:Organization # WRONG: SocialMovement is a specific TYPE of Organization
+```
+
+✅ **CORRECT**:
+```yaml
+SocialMovement:
+  broad_mappings:
+    - schema:Organization # CORRECT
+```
+
+### Verification Checklist
+
+- [ ] Does the `exact_mapping` represent the **exact same scope**?
+- [ ] If the external term is a generic parent class (e.g., `Type`, `Concept`, `Entity`), move it to `broad_mappings`.
+- [ ] If the external term is a specific instance or subclass, check `narrow_mappings`.

+# Rule: No Rough Edits in Schema Files
+
+**Identifier**: `no-rough-edits-in-schema`
+**Severity**: **CRITICAL**
+
+## Core Directive
+
+**DO NOT** perform rough, imprecise, or bulk text substitutions (like `sed -i` or regex-based python scripts) on LinkML schema files (`schemas/*/linkml/`) without guaranteeing structural integrity.
+
+**YOU MUST**:
+*   ✅ Use proper YAML parsers/dumpers if modifying structure programmatically.
+*   ✅ Manually verify edits if using text replacement.
+*   ✅ Ensure indentation and nesting are preserved exactly.
+*   ✅ Respect comments and ordering (which parsers often destroy, so careful text editing is sometimes necessary, but it must be PRECISE).
+
+## Rationale
+
+LinkML schemas are highly structured YAML files where indentation and nesting semantics are critical. Rough edits often cause:
+*   **Duplicate keys** (e.g., leaving a property behind after deleting its parent key).
+*   **Invalid indentation** (breaking the parent-child relationship).
+*   **Silent corruption** (valid YAML but wrong semantics).
+
+## Examples
+
+### ❌ Anti-Pattern: Rough Deletion
+
+Deleting lines containing a string without checking context:
+
+```python
+# WRONG: Deleting lines blindly
+for line in lines:
+    if "some_slot" in line:
+        continue # Deletes the line, but might leave children orphaned!
+    new_lines.append(line)
+```
+
+**Resulting Corruption**:
+```yaml
+# Original
+slots:
+  some_slot:
+    range: string
+
+# Corrupted (orphaned child)
+slots:
+    range: string  # INVALID!
+```
+
+### ✅ Correct Pattern: Structural Awareness
+
+If removing a slot reference, ensure you remove the entire list item or key-value block.
+
+```python
+# BETTER: Check for list item syntax
+if re.match(r'^\s*-\s*some_slot\s*$', line):
+    continue
+```
+
+## Application
+
+This rule applies to ALL files in `schemas/20251121/linkml/` and future versions.

+# Rule: Ontology Detection vs Heuristics
+
+## Summary
+When detecting classes and predicates in `data/ontology/` or external ontology files, you must **read the actual ontology definitions** (e.g., RDF, OWL, TTL files) to determine if a term is a Class or a Property. Do not rely on naming heuristics (like "Capitalized means Class").
+
+## Detail
+*   **Verification**: Always read the source ontology file or use a semantic lookup tool to verify the `rdf:type` of an entity.
+    *   If `rdf:type` is `owl:Class` or `rdfs:Class`, it is a **Class**.
+    *   If `rdf:type` is `rdf:Property`, `owl:ObjectProperty`, or `owl:DatatypeProperty`, it is a **Property**.
+*   **Avoid Heuristics**: Do not assume that `skos:Concept` is a class just because it looks like one (it is), or that `schema:name` is a property just because it's lowercase. Many ontologies have inconsistent naming conventions (e.g., `schema:Person` vs `foaf:Person`).
+*   **Strictness**: If the ontology file is not available locally, attempt to fetch it or consult authoritative documentation before guessing.
+
+## Violation Examples
+*   Assuming `ex:MyTerm` is a class because it starts with an uppercase letter without checking the `.ttl` file.
+*   Mapping a LinkML slot to `schema:Thing` (a Class) instead of a Property because you guessed based on the name.

+    *   *Example*: `DigitalPlatformType`, `WarehouseType`.

     comments:
       - vCard Address is the primary ontology class (RFC6350 standard)
       - Use structured components when available, address_formatted as fallback
       - Multiple addresses supported via has_or_had_address slot (multivalued, Rule 39 compliant)
       - address_type distinguishes headquarters, legal, visiting, mailing, storage
       - Coordinates (lat/lon) optional but recommended for visualization/mapping

   AddressComponent:
     class_uri: hc:AddressComponent
-    description: |
-      A single component of a structured address.
-
-      **PURPOSE**:
-
-      AddressComponent represents one discrete element of an address, such as 
-      the street number, street name, city, region, or country. This enables:
-      - Parsing addresses from various sources into standardized components
-      - Normalizing address data from different formats/APIs
-      - Supporting multilingual address representations (long_name vs short_name)
-
-      **COMPONENT STRUCTURE**:
-
-      Each AddressComponent has:
-      - `long_name`: Full form of the value (e.g., "Netherlands", "Noord-Holland")
-      - `short_name`: Abbreviated form (e.g., "NL", "NH") - may equal long_name
-      - `has_or_had_type`: Semantic type(s) via ComponentType (e.g., Country, Locality)
-
-      **STANDARD COMPONENT TYPES**:
-
-      | Type | Description | Example long_name | Example short_name |
-      |------|-------------|-------------------|-------------------|
-      | `street_number` | House/building number | "1", "221B" | same |
-      | `route` | Street/road name | "Museumstraat" | same |
-      | `locality` | City/town/village | "Amsterdam" | same |
-      | `postal_code` | ZIP/postal code | "1071 XX" | same |
-      | `subregion` | County/district | "Amsterdam" | same |
-      | `region` | State/province | "Noord-Holland" | "NH" |
-      | `country` | Country | "Netherlands" | "NL" |
-      | `premise` | Building/complex name | "Rijksmuseum" | same |
-      | `subpremise` | Unit/floor/suite | "Floor 3" | "3" |
-
-      **RELATIONSHIP TO Address CLASS**:
-
-      AddressComponent is used for:
-      1. **Parsing workflows**: Breaking down raw address strings into components
-      2. **Normalization**: Standardizing addresses from different sources
-      3. **Intermediate representation**: Before constructing a full Address object
-
-      The Address class provides the final, ontology-aligned representation with 
-      dedicated slots (street_name, locality, region, country_name, etc.).

-      **SOURCE-AGNOSTIC DESIGN**:
-
-      This class is designed to work with addresses from ANY source:
-      - Website scraping
-      - Registry data (ISIL, KvK, etc.)
-      - API responses (when normalized)
-      - Manual data entry
-      - OCR/document extraction
-
-      API-specific raw data formats are handled by Endpoint classes.

+    description: "A single component of a structured address.\n\n**PURPOSE**:\n\n\
+      AddressComponent represents one discrete element of an address, such as \nthe\
+      \ street number, street name, city, region, or country. This enables:\n- Parsing\
+      \ addresses from various sources into standardized components\n- Normalizing\
+      \ address data from different formats/APIs\n- Supporting multilingual address\
+      \ representations (long_name vs short_name)\n\n**COMPONENT STRUCTURE**:\n\n\
+      Each AddressComponent has:\n- `long_name`: Full form of the value (e.g., \"\
+      Netherlands\", \"Noord-Holland\")\n- `short_name`: Abbreviated form (e.g., \"\
+      NL\", \"NH\") - may equal long_name\n- `has_or_had_type`: Semantic type(s) via\
+      \ ComponentType (e.g., Country, Locality)\n\n**STANDARD COMPONENT TYPES**:\n\
+      \n| Type | Description | Example long_name | Example short_name |\n|------|-------------|-------------------|-------------------|\n\
+      | `street_number` | House/building number | \"1\", \"221B\" | same |\n| `route`\
+      \ | Street/road name | \"Museumstraat\" | same |\n| `locality` | City/town/village\
+      \ | \"Amsterdam\" | same |\n| `postal_code` | ZIP/postal code | \"1071 XX\"\
+      \ | same |\n| `subregion` | County/district | \"Amsterdam\" | same |\n| `region`\
+      \ | State/province | \"Noord-Holland\" | \"NH\" |\n| `country` | Country | \"\
+      Netherlands\" | \"NL\" |\n| `premise` | Building/complex name | \"Rijksmuseum\"\
+      \ | same |\n| `subpremise` | Unit/floor/suite | \"Floor 3\" | \"3\" |\n\n**RELATIONSHIP\
+      \ TO Address CLASS**:\n\nAddressComponent is used for:\n1. **Parsing workflows**:\
+      \ Breaking down raw address strings into components\n2. **Normalization**: Standardizing\
+      \ addresses from different sources\n3. **Intermediate representation**: Before\
+      \ constructing a full Address object\n\nThe Address class provides the final,\
+      \ ontology-aligned representation with \ndedicated slots (street_name, locality,\
+      \ region, country_name, etc.).\n\n```\nRaw Address Data (any source)\n    │\n\

+      ```\n\n**USAGE EXAMPLES**:\n\n```yaml\n# Street number component (MIGRATED 2026-01-22:\
