Claude Code v2.1.219 ·

Index-based memory recall behind tengu_mill_orange

Memory recall could pick documents from a search index instead of asking the model, but it is disabled.

An index-backed recall path with detailed timing telemetry sits behind tengu_mill_orange, which falls back to false.

What

Memory recall has a new branch that selects documents from a search index rather than asking the model to pick, switched off in this build.

Details
  • The search entry point takes four extra arguments; when the first is true the new branch uses searchMemoryFilesWithIndex in place of the model-driven memory selector.
  • Emits a memory_recall_select event with via_index, candidate_docs, index_query_term_count, index_hit_count, index_below_floor_count, index_top_score, index_relevance_floor, index_loaded_from_disk, index_took_ms, index_store_held, index_open_wait_ms and index_store_open_ms.
  • Failure reasons: index_sweep_incomplete, index_query_failed, below_relevance_floor, no_servable_hits, partially_below_floor, all_filtered.
  • Gated on tengu_mill_orange, whose in-source fallback is false; with it off the old selector path runs unchanged.

What has happened since
Flag reading moved The flag server now returns off for tengu_mill_orange, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
