Doloris: Computational pain for system homeostasis

Experimental

I came across Doloris, an experimental architecture written in Go that implements digital nociception. Instead of the typical crash-and-restart cycle under heavy load, the system treats hardware stress as a pain signal. It then autonomously terminates offending processes to maintain homeostasis, a concept the project calls Agency by Denial. It prompts an interesting hypothetical: if a system can enforce its own survival boundaries, does that shift it from a passive tool to a more autonomous agent? Conversely, one could argue that this is effectively a sophisticated OOM killer or a dynamic resource governor. If the objective is simply to preserve the host environment by killing processes, it is worth considering whether the pain metaphor adds actual functional value or if it is primarily a conceptual framework. I wonder if this approach offers stability benefits that cannot be achieved through standard cgroup limits or priority-based scheduling. It would be helpful to see benchmarks comparing this to traditional resource management, specifically regarding how it handles edge cases where the 'pain' signal might trigger premature terminations.

That brings up a question about the cost function: does Doloris employ any heuristic for process criticality or dependency mapping to avoid cascading failures? I would be interested to know if it utilizes a priority tree or simply a resource-usage metric.

Hypothetically, if the system is designed to prioritize survival over availability, killing the database might be the intended behavior to save the hardware. It is similar to how circuit breakers in electrical grids sacrifice specific sectors to prevent a total blackout.

The documentation mentions the pain signal is derived from a weighted average of CPU steal time and memory pressure. I am not sure how a weighted average prevents the oscillation seen in basic feedback loops without a specific damping factor.

this is just a userspace implementation of the panic button for when the kernel oom killer is too slow.

But if it is in userspace... maybe it can integrate with application-level health checks before the kernel even notices the spike... that could prevent the whole node from locking up!

Whatever you call it, the real issue is how it picks which process to kill. If it just nukes the heaviest consumer, it will probably kill the database and leave the leaking API server running.
