A follow-up sent during an active run now offers itself to the running
agentic loop via POST /api/ai/sessions/{id}/steer. Accepted steers join
the loop at its next turn boundary (the abort-check site) as plain user
messages, are announced with a steer_applied stream event so the drawer
settles the pending row, and persist through the end-of-run save. A
steer carries prompt text only: no route, control-level, or autonomy
changes, no turn-budget extension, system sessions rejected, and the
per-session inbox is bounded (steer_backlog overflow). Delivery is not
guaranteed by acceptance: a run that ends first discards the inbox and
the row drains as an ordinary queued turn, so pre-steering queue
semantics remain the fallback. Steering rows lose edit/remove once
accepted.
Chat turns, compaction, and title calls now stamp session_id on their
cost.UsageEvent, and the done event carries session_cost_usd summed from
the operator ledger (cost.Store.SessionCostUSD). The drawer's last-turn
summary appends '$0.12 session' with a sub-cent floor. The figure is
omitted whenever any of the session's models has unknown pricing, and
free local models price known-at-zero, so no figure is ever partial.
Preserve workflow activity rows across active stream content and tool boundaries, and type the generated chat SSE route metadata that drives model activity rows.
Persist approval requests as governed planned actions with context confidence and stream that plan into Pulse Assistant approvals.
Reuse the planned action identity when approved actions execute so the unified audit trail stays continuous.
