[Pi] ctx_reduce does not remove tool outputs after the execute threshold; historian compaction becomes a no-op

[aoguai]

Short description

ctx_reduce is triggered after the execute threshold, but no tool outputs are removed. The context keeps growing above the model limit, and historian compaction repeatedly reports that there are no eligible entries.

What happened?

After switching Pi to magic-context, automatic context reduction frequently stops working.
The plugin detects that the context has exceeded the execute threshold and enters the forced materialization path, but the reduction phase does not actually drop any tool outputs. The context then continues growing until it reaches several times the configured limit.
Observed behavior from recent Pi sessions:

1. At approximately 120% context usage, the plugin selected the forced execute path.
2. The cleanup stage reported:
   • getDroppedTagsByNumbers ... fetched=0
   • emergency tiered drop skipped: no-candidates
   • droppedTools=0
   • staleReduce=0
3. At approximately 179% usage, the plugin entered the emergency path and started a historian subprocess, but the child process was terminated with SIGTERM before producing a usable compaction result.
4. Later attempts repeatedly reported:
   • emergency tiered drop skipped: pressure-episode-latched
   • historian no-op: protectedTailStart=43/45 eligibleEnd=2 <= offset=2 — nothing to compact
5. The same session eventually reached approximately 313–315% usage while tool outputs were still present.
   The most suspicious part is that the execute threshold is detected correctly, but the reducer cannot resolve any eligible tool-output tags. The historian also appears to protect almost the entire message history, leaving an empty eligible range. Once the pressure episode is latched, subsequent emergency cleanup attempts are skipped instead of forcing a recovery path.

The reducer appears to have a state/identity mismatch between Pi message entries, reduction tags, and the historian eligibility window. The execute threshold is reached, but the reducer resolves zero tagged tool outputs (fetched=0), while historian protection leaves no eligible entries. The pressure-episode latch then prevents fallback cleanup from running again. The SIGTERM termination of the historian subprocess may further leave the session in a partially updated state.

Thanks for the full logs. There are real reclaim failures here, but getDroppedTagsByNumbers ... fetched=0 is not evidence of an identity mismatch: that query fetches tags already marked dropped, not all tagged tool outputs.

Three mechanisms explain the stalled cleanup:

1. emergency tiered drop skipped: no-candidates: the first pass had fewer tags than your protected_tags: 24 window. Emergency selection still honored that window and the per-tier recency reserve, so it could reclaim nothing.
2. pressure-episode-latched followed by droppedTools=0: that zero-drop evaluation nevertheless consumed the emergency episode's batch. Later completed tool outputs could not start a batch while pressure remained high. We now latch only after an actual removal. Batches that do remove content still retain the one-batch-per-pressure-episode rule, rather than rewriting the prompt on every tool call. At 95% or higher, emergency selection also yields the tag/recency reserves; open tool calls awaiting results and the newest three ctx_reduce examples remain protected. The applying drop-all-tools message is being replaced with evaluating tiered emergency reclaim, which describes the actual target-driven behavior.
3. protectedTailStart=43 eligibleEnd=2 <= offset=2: the protected tail had moved forward, but the separate per-run head cap could land inside the first large completed tool exchange. Preserving the whole exchange then moved the cap back to the starting offset. This is not an unconditional snap to the sole user prompt: a uniform 120-tool single-turn fixture already has an eligible head. We reproduced the empty-head failure with a large first completed exchange. Under force pressure, the fix admits that whole first exchange if it ends before the protected tail, without splitting invocation/result pairs or crossing a recent open call. Both Pi and OpenCode have regression tests, including actual compartment publication.

The 04:08:00.064Z ... signal=SIGTERM was not a historian killed before producing a result. Immediately before it, the full log records terminal stopReason=stop events at 04:07:58; immediately afterward it records a queued drop, a published compartment, and historian_complete. Our Pi subprocess runner terminates a print-mode child that has not exited two seconds after its terminal response. The emergency wait is a separate 30-second wait and does not cancel that child. We are not extending a timeout based on this event.

These fixes will ship in 0.41.4.

For today: stop/end the long-running turn and continue in a fresh session with a short handoff; lowering protected_tags before the next run reduces the chance of the initial no-candidate trap. Lowering it after the episode is already latched is not a reliable repair on 0.41.3, and /ctx-wrapup may still meet the same empty eligible range. There is no dependable in-place workaround for an already-stuck marathon turn.
