Part 2: Newer context shouldn’t automatically become “truth”
Once you separate memory, live state, research, and execution evidence, you still need a way to decide what happens when they disagree.
My answer is: newer does not automatically win.
A newer timestamp can still come from the wrong source.
Research published yesterday should not overwrite a project decision just because it’s fresh.
A recent chat message should not quietly replace durable project memory.
And an old memory entry should not beat the live repository when the question is about current implementation state.
So each piece of context needs more than content. It needs things like:
Where did this come from?
What scope does it belong to?
How fresh is it?
What kind of authority does that source actually have?
Does it explicitly supersede something older?
That last one matters.
I don’t really want old information to disappear when something changes. I want it to stop being treated as current while still remaining available as history and evidence.
So the rule is closer to:
authority + explicit supersession + freshness
not simply “latest timestamp wins.”
That also makes drift much easier to reason about.
If live implementation has moved beyond remembered project state, that’s a drift condition.
If two sources both appear to claim current authority over the same thing, that’s a different problem.
And if a source is simply unavailable, that’s not drift at all. That’s a retrieval failure.
Those cases shouldn’t all collapse into “the memory looks stale, update it.”
That’s the part I think a lot of memory systems skip: retrieval is only half the problem.
The harder question is:
Once you retrieve multiple versions of reality, what is actually allowed to outrank what?
Curious how others are handling this.
Do you use explicit supersession/authority rules, or mostly rely on timestamp + retrieval ranking to decide which context wins?
