Render the Advisor spend next to the primary-model cost as `$2.67 (sub) + $0.41 (adv)`, leaving the status line unchanged until an Advisor cost exists.
Record the cost from finalized advisor `message_end` events in a per-session ledger instead of deriving it from the live advisor transcript, so an in-session compaction or any other history rewrite no longer resets the reported spend. The ledger is cleared for a new session and once a different-session switch commits, and survives a switch that rolls back.
The advisor overflow-compaction one-shot calls compact() directly, bypassing the advisor Agent and its metadata resolver, so it omitted metadata.user_id. Resolve the advisor's session metadata per candidate provider (after credential selection) and pass it into the compact() options alongside sessionId/promptCacheKey. Add a regression test asserting the direct compaction request carries the advisor session id.
- 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.
