Pure additions announce only the new entries and pure removals name
what is gone, instead of restating the full list on every change.
Description or instruction edits still restate the superseding list.
Reconcile never rewrites the baseline; only rebaseline (compaction) and
initialize (first turn) produce baseline text. The durable Applied record
tracks what the model was last told, per source.
- Incompatible stored values re-announce the source baseline as an update
instead of forcing a full replacement
- Sources removed without removal text retain the model's belief silently;
entries self-clean at the next rebaseline
- Rebaseline restates unobservable sources from their last-applied values
instead of blocking; ReplacementBlocked and ReplacementReady are gone
- Rename Snapshot to Applied and Generation to Baseline {text, applied}
