-The `d` tag is required regardless of whether the target kind is normally addressable. For addressable event kinds (30000-39999), the `d` tag serves its usual role. For all other kinds, the `d` tag enables grouping and correlation with the pointer.
-
 ### Resolution Algorithm
 
 To resolve the current state of collaboratively-owned content:
 
-1. Parse the `39382` pointer event to extract owners (`p` tags) and target kind (`k` tag)
-2. Extract the identifier from the `d` tag
-3. Query: `{"kinds": [<target-kind>], "authors": [<all-owners>], "#d": ["<identifier>"]}`
-4. For addressable target kinds: return the event with the highest `created_at`
-5. For non-addressable target kinds: return all matching events that contain a valid `a` tag backlinking to the pointer
-
-### Initial Discovery
-
-Clients that do not yet have any version of the event MUST query by `#d` tag alone or by known owner pubkeys.
+1. Collect owners from the `39382` pointer's `p` tags (plus the pointer's pubkey)
+2. Query: `{"kinds": [<target-kind>], "authors": [<all-owners>], "#d": ["<identifier>"], "limit": 1}`
+3. Return the most recent event
 
 ## Client Behavior

 An event without a verifiable `a` tag backlink to a `39382` pointer MUST NOT be presented as collaboratively authored. This prevents spoofed co-authorship claims.
 
-### Display Recommendations
-
-- Clients SHOULD display which pubkey signed each version
-- Clients SHOULD indicate when an event is part of a collaborative set
-- Clients MAY show the full owner set from the pointer event alongside the signing pubkey

-2. Parses owners: `[alice, bob, carol]`, target kind: `30023`
-3. Queries: `{"kinds": [30023], "authors": ["alice", "bob", "carol"], "#d": ["collaborative-guide"]}`

-## Security Considerations
-
-- Owners can unilaterally modify content
-- An `a` tag backlink alone is insufficient — clients MUST verify the referenced pointer event includes the author in its `p` tags
-- Owner changes on the pointer event take effect immediately; old target events from removed owners are no longer authoritative
