Subject: [PATCH] Add new slot definitions for refer_to, remove, reported_on,
 signed_by, and specified_as

- Introduced `refer_to` slot to link identifiers to entities, with ontology alignment to CIDOC-CRM and DCTerms.
- Added `remove` slot for recording objects removed during deaccessioning, aligned with CIDOC-CRM properties.
- Created `reported_on` slot to capture URIs of reports documenting entities, with mappings to CIDOC-CRM and Schema.org.
- Implemented `signed_by` slot to identify individuals who signed documents, referencing RiC-O and Schema.org.
- Established `specified_as` slot to indicate the precision level of place references, with broad mappings to CRM and DQV.

+# Rule: No Autonomous Alias Assignment
+
+**Status**: ACTIVE
+**Created**: 2026-02-10
+
+## Rule
+
+The agent MUST NOT assign aliases to canonical slot files on its own. Only the user decides which `new/` slot files are absorbed as aliases into which canonical slots.
+
+## Rationale
+
+Alias assignment is a semantic decision that determines the conceptual scope of a canonical slot. Incorrect alias assignment conflates distinct concepts. For example, `membership_criteria` (eligibility rules for joining) is not an alias of `has_mission` (organizational purpose), even though both relate to organizational governance.
+
+## What the agent MUST do
+
+1. When creating or polishing a canonical slot file, leave the `aliases` field empty unless the user has explicitly specified which aliases to include.
+2. When processing `new/` files, present candidates to the user and wait for their alias assignment decisions.
+3. Do NOT delete `new/` files until the user confirms the alias mapping.
+
+## What the agent MUST NOT do
+
+- Autonomously decide that a `new/` file should become an alias of a canonical slot.
+- Add alias entries without explicit user instruction.
+- Delete `new/` files based on self-determined alias assignments.

+        Particulate matter measurement is a domain-specific environmental
+        monitoring concept with no direct equivalent in standard ontologies.
+        SOSA provides the general observation/result framework under which
+        such measurements would be modelled, but does not define
+        substance-specific properties.

+        Common particle size classifications include PM2.5 (fine particles
+        ≤2.5 µm) and PM10 (coarse particles ≤10 µm). Heritage institutions
+        typically target PM2.5 levels below 10 µg/m³ for sensitive collections.

-
-      ```yaml
-
-      occupation: "http://www.wikidata.org/entity/Q1028181"  # painter

-    - This is THE identifying property for Person entities. All other properties and relationships connect through this hub identifier.
-    - The path component after /person/ is a lowercased, hyphenated slug derived from the person's preferred name, with optional disambiguators.
-    - Unlike custodian GHCID, person_id does not embed geographic or type codes since persons are mobile and may work at multiple institutions.
