Post-compaction premise-drift guard. After a compaction/summary event, it extracts distinctive literal anchors (file paths, quoted literals, key=value pairs, error codes) from the shadowed span's text, checks whether the committed summary still contains them, and — when a critical anchor vanished — injects a one-shot notice into the next step telling the model what it may have lost and how to recover it from the append-only log.
Why
Recall-oriented designs (recallable-compaction, session-query tools) make shadowed content reachable when suspected. Nothing says "you just dropped a key fact". This guard turns the compaction summary into a checked handoff: the model learns the moment a path, value, or error string it was relying on is no longer in the summarized context.
How it works
| Hook | Role |
|---|---|
session/event (compaction/summary) | Re-derives the shadowed span's text from shadowedSeqs (the log keeps every byte), extracts anchors, and compares against event.data.summary. |
agent/pre-step | Injects one notice (plugin source) naming up to maxAnchors vanished anchors and the shadowed seq range, once per alarm; a new user prompt skips delivery. |
Anchor extraction is deterministic and pure — no LLM calls, no new storage.
Config
| Field | Default | Meaning |
|---|---|---|
maxAnchors | 5 | Vanished anchors named in one notice. |
minAnchorLength | 6 | Anchors shorter than this are never critical. |
maxNoticeChars | 400 | Notice text cap. |
All three must be integers >= 1; misconfiguration throws at plugin load.
