 - Before answering a prompt that depends on current state, verify the latest relevant files instead of relying only on conversation history.
+- For any meaningful prompt, decide whether the interaction adds, corrects, or sharpens project memory.
 - When the user provides new durable information, update the right workspace files before or while answering.

   - durable project knowledge goes to `ai/context/project.md`
   - confirmed team or manager communication preferences go to `ai/context/people/jeff.md`
   - confirmed decisions go to `ai/context/decisions/`
+- Default to writing new same-day information to today's log unless a more durable destination is clearly better.
+- Update preexisting memory when a new prompt clarifies or corrects something already stored.
+- Do not wait for a dedicated sync command if the correct memory update is already obvious.
 - Do not over-promote uncertain information. Keep uncertain items in the daily log.
 - When drafting communication, preserve technical meaning and improve clarity in natural US English.
