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

Preferences (food, travel, work style, tools, habits), family (names, birthdays, events, schools, milestones), recurring schedule patterns, contacts (who someone is + relationship + context), seriously-stated opinions, personal plans (trips, purchases, home projects), 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); reuse existing files when a category fits, create new files for genuinely new topics.
Add or update its one-line entry in /workspace/trusted/MEMORY.md.
Append to today's daily log.

When NOT to save

Ephemeral task context, facts already in memory (check MEMORY.md first), jokes / sarcasm / hypotheticals, and anything derivable from code / git / 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.
