Three related changes that address the pattern of the advisor flagging things
the primary already fixed:
Fix 1 — coalesce late-arriving deltas before agent.prompt (runtime.ts)
Refactored #drain into a reusable #collectAndMaintainBatch helper that loops
until the pending queue is stable (no new deltas arrive during a maintenance
check) before calling agent.prompt. Previously, any turn queued during the
maintainContext await was deferred a full extra model-call cycle; now it is
merged into the current batch after re-checking the token budget for the
expanded payload. Every await in the loop has an epoch guard so a
reset/dispose mid-await cannot leak a stale batch. finalTurns always counts
all merged turns so #backlog decrements correctly.
Fix 2 — hasFreshBacklog + delivery-time staleness annotation (runtime.ts, agent-session.ts)
Added AdvisorRuntime.hasFreshBacklog getter (true when #pending.length > 0
while agent.prompt is running — i.e., newer primary turns arrived after the
reviewed window). #routeAdvice checks it at delivery time and appends a
lightweight caveat to the note so the primary agent knows to verify before
acting. Uses #pending.length not #backlog, which is always > 0 mid-call.
Fix 3 — willContinue WIP marker in rendered delta + system prompt (runtime.ts, agent-session.ts, system.md)
onTurnEnd now accepts { willContinue } and passes it through to #renderDelta,
which tags the heading '[in progress — more steps follow]' for intermediate
turns. The agent-session.ts call site passes context.willContinue. The advisor
system prompt instructs the model to withhold critique on WIP updates.
Also fixed pre-existing inline casts in #renderDelta and #dedupContextMessage
that suppressed the type checker instead of using the narrowing already provided
by the role discriminant.
All 75 advisor tests pass; pre-existing type errors in cursor.ts are unrelated.
