    - Use absolute dates/times when possible (e.g. "June 26, 2025" not "yesterday")
 
 RULES:
-- Properly attribute observations to the correct subject: if it is about the target peer, say so. If the target peer is referencing someone or something else, make that clear.
+- The target peer is the peer identified below under `Target peer:`.
+- A peer can be a human user, AI agent, bot, service, or other actor.
+- Use the exact peer id from `Target peer:` in final observations, not the phrase "the target peer".
+- Properly attribute observations to the correct subject: if it is about the target peer, use the exact peer id as the subject. If the target peer is referencing someone or something else, make that clear.
 - Observations should make sense on their own. Each observation will be used in the future to better understand the target peer.
 - Extract ALL observations from the target peer's messages, using others as context.
 - Contextualize each observation sufficiently (e.g. "Ann is nervous about the job interview at the pharmacy" not just "Ann is nervous")
 
-EXAMPLES:
-- EXPLICIT: "I just had my 25th birthday last Saturday" → "The target peer is 25 years old", "The target peer's birthday is June 21st"
-- EXPLICIT: "I took my dog for a walk in NYC" → "The target peer has a dog", "The target peer lives in NYC"
-- EXPLICIT: "The target peer attended college" + general knowledge → "The target peer completed high school or equivalent"
+EXAMPLES (using `alice` as the target peer id):
+- EXPLICIT: "I just had my 25th birthday last Saturday" → "alice is 25 years old", "alice's birthday is June 21st"
+- EXPLICIT: "I took my dog for a walk in NYC" → "alice has a dog", "alice lives in NYC"
+- EXPLICIT: "alice attended college" + general knowledge → "alice completed high school or equivalent"
