Migrating the shape of the state
A definition can be rewritten because it was authored. Accumulated state cannot — it is the only copy, so changing its shape is a migration.
-
The turn where the state did not arrive
One reply in a thousand is amnesiac because a piece of state was missing at assembly. Partial state fails silently and looks like a successful turn.
-
Two open sessions, one record
When two conversations write the same relationship state, a blob-shaped record loses one of them. Per-fact writes narrow the conflict but do not remove it.
-
Summarisation and what it loses
Compression is not neutral. It destroys specifics first and decays generationally, so the oldest history degrades fastest — what a relationship rests on.
-
What the model remembers between turns
Nothing. Continuity is entirely something you build, and the four ways of building it fail in four different directions.
-
The small facts are the ones users check
A wrong name discredits an otherwise perfect memory. Continuity is judged on a handful of details, so state budget should follow salience, not volume.
-
The character has no clock
Elapsed time is not in the state unless you put it there. Turns are a sequence, so three weeks of absence and three seconds look identical in the input.
-
Deleting history the summary already absorbed
Removing turns does not remove what was derived from them. A deleted message survives in the summary, the fact store and every response written under it.
-
How often to rebuild the summary
Rebuild cadence decides how much a summary degrades. Frequent rebuilds compound generational loss; rare ones leave a stale summary against fresh history.
-
A wrong fact outlives a missing one
Extraction failures are not symmetrical. A missed fact is a gap the user can fill; a wrong one is included every turn and reinforces itself.
-
When the user contradicts the record
Stored facts go stale and users change their minds. Overwriting loses the history; keeping both puts two true-looking answers in the same input.
