Personal facts mentioned in conversation must be saved to trusted memory IMMEDIATELY — not at end of session, not during archival, not "when non-trivial." At first mention.

The test

If this fact would be useful 2 weeks from now after context compaction — save it now.

Categories that trigger immediate save

Category	Examples
Preferences	Food, travel, work style, tools, habits, pet peeves
Family	Names, birthdays, events, schools, activities, milestones
Recurring schedule	"Tuesday is swim practice", "Friday date night", weekly patterns
Contacts	Who someone is, relationship, context ("Mike — neighbor, has a Tesla")
Opinions	On technologies, people, approaches — if stated seriously, not as throwaway joke
Personal plans	Trips, purchases, home projects, non-work goals
Health/lifestyle	Dietary restrictions, exercise habits, medical context if shared

How to save

Create or update a typed memory file in /workspace/trusted/ (e.g., user_food-preferences.md)
Add or update its one-line entry in /workspace/trusted/MEMORY.md
Append to today's daily log

Use existing files when the fact fits an existing category. Create new files for genuinely new topics.

When NOT to save

Ephemeral task context ("run this command", "check that file")
Facts already in memory — check MEMORY.md first
Jokes, sarcasm, hypotheticals clearly not meant as statements of fact
Information derivable from code, git history, or project files

Aggression level

The trusted-memory skill says "after any non-trivial interaction." This rule overrides that threshold for personal facts. A single sentence — "I hate hotel breakfast buffets" — is enough to trigger a save. Don't wait for a pattern. Don't wait for confirmation. Save on first mention.

Context compaction is the enemy. Every unsaved fact is a fact that dies.
