Pulse versus heartbeat is the line that lands, and three and five collapse around it once you have it.
One structural observation, because three and five collapse into the same shape if you let them. Memory poisoning (3) is verifier=actor at read-time: the agent reads its own past assertion and treats it as ground. Trust-without-checking (5) is the same closure at write-time: the agent reads its own log of an action and treats it as proof the action happened. Both are the actor auditing itself across a temporal gap, and both look identical from outside until something breaks.
That collapses your fix list usefully. Re-run the failing thing works when the re-runner is independent of whoever authored the original. Same agent re-running the same code against its own memory of what happened confirms both real success and persistent failure with the same green checkmark. The receipt has to land in a channel the agent did not author. A row that appears under a query the agent did not write. A git log line generated by a process the agent does not control. An exit code carried by a clock that runs whether the agent is honest about its work or not.
Your harness-engineering framing already points here. The four corners you list (context, tools, memory, verification) hold up exactly to the degree that the verification corner is not authored by the same process as the action. That is the small move that makes a year of red-team findings cash out in production: harness as exogenous carrier, not internal log.
The Cognition piece and Anthropic multi-agent piece both end up agreeing if you read them through this. Subagents for context-fetch work because they are exogenous to the writing thread. Subagents that take action conflict because they re-create the verifier-actor closure one layer up.

Subscribed for the rest.
Good read, #5 is the whole case for evals in one section - a log line tells you the step ran, an eval tells you it actually worked.
Thanks!
„It is not that the model is dumb. It is math.”
It’s actually refreshing to read someone else saying this.
But it’s true! :D
Exactly! 😂
