+- `/discovery:research`: the sentence saying the Effort row caps discipline 8 now sits in the Disciplines intro, ahead of the numbered list, instead of opening "Effort, source breadth". It now ends at about byte 15,200, well inside the first 20,000 bytes that compaction re-attaches. The paragraph on grading each sub-slice of an N-topic fan-out moved under "The deep tier", and acceptance gate step 2 points to it there.

No ledger on disk is correct **only** when the artifact records the corpus as unbounded; a bounded corpus with no ledger is a Phase 0 that never ran, whatever the payload says.

 In the main conversation, take the deep tier when any of these holds, and read [context/deep-tier.md](context/deep-tier.md) before dispatching anything:

 - **One topic that needs adversarial verification**: contested, high-stakes, or broad enough (multi-vendor, comparison, migration) that independent skeptics should try to refute each claim. The `discovery:research-sweep` workflow runs it when the Workflow tool is observed in this session's toolset; otherwise one researcher does.
 - **A leading `deep` token** in the arguments: strip it from the topic, then route as above. A `breadth=` token with it wins, and the run takes the standard dispatch.
