- Anchored advisor compaction on provider-reported context usage (cached
input + generated output) floored by a full local estimate including the
advisor system prompt and tool schemas, so a near-full cached context is no
longer undercounted by the per-message estimate.
- Rejected stale provider usage retained across advisor compaction via a
runtime-only usage-anchor boundary recorded on the summary message.
- Recovered provider overflow by clearing only the advisor's own context at
the current primary cursor, retrying the bounded failing batch once against
a fresh context without replaying old primary history, and keeping later
updates eligible.
- Threaded the selected dashboard range through the stats Recent Errors UI,
API, and database timestamp filter before ordering and the 50-row limit.
