One way of doing this reuses the prompt cache, a stored copy of the conversation that the API can pick up again cheaply.\n\nThat path now reports progress while the summary streams in. The indicator shows how much of the response has arrived and that the model is responding. The fallback summarizer now also shows a \"requesting\" state at the start of every attempt, not only on retries.\n\n**Why**\n\nThe compaction indicator should stop looking frozen while the cache-reusing summary is being written.\n\n- Flag `tengu_compact_cache_prefix`: Off in both readings (read for one account on one subscription tier against v2.1.283; this account: off, anonymous baseline: off, compiled default: on) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Compaction\n- Tier: Nothing to try yet\n- Useful: 1\/5\n- Signal: 3\/5\n- Present in the build but not switched on"}
