The coherence census collects reads of real agents. Each row carries the trace the read consumed, the mapping from that trace to committed state, and the exact command that produced the read, so anyone can run the row again and reach the same finding. The census lives at github.com/RightRudderAI/coherence-census.
Full runs
In our reread of DBOS's own Hacker News research agent, vendored unchanged and run on gpt-4o-mini through OpenRouter across five topics at ten iterations each on 2 September under fathom-read 0.4.1, the agent as it shipped repeated 14 of its 50 searches, re-read 42 percent of the threads it fetched, and held 516 stories more than once. With the repair in front of the step where the agent proposes its next queries, the repeats fell to 0 of 50, the re-reads to 12 percent, and distinct threads covered rose 35 percent, at the same model and the same iteration count.
We read CrewAI's book-writing flow, an outline crew and per-chapter crews on CrewAI 1.15.21, run on three models through OpenRouter at three runs each and captured under fathom-read 0.3.0 in September 2026. On gpt-4o-mini the flow read coherent across all three runs. On llama-3.3-70b-instruct it drew duplicate commits in bulk, 28 in one run and 21 in another, along with two stale references, and the span read matched the event-bus read finding for finding. On mistral-small-3.2-24b it read coherent but for two duplicate commits in a single run.
We read a DeepAgents deep-research run on deepagents 0.7.14 with langchain-fathom, an orchestrator delegating to a sub-agent through task calls with Tavily search, on llama-3.3-70b through OpenRouter, asked to compare five long-term memory systems. The run made 6 tool calls, held one source, and delivered its report with a single citation. The read returned one stale reference, since the report cited a source whose URL slug it had reordered from the article the committed state actually held.
Earlier reads
The census grew out of reads we ran on production frameworks, each showing where an agent's own record and its reported outcome part ways.
