+- issue: https://github.com/PyAutoLabs/PyAutoFit/issues/1530 (issued 2026-08-27)
+- issued: 2026-08-27
+- prompt: active/xla_cpu_eigen_pool_deadlock.md
+- status: not started — research follow-up to the shipped jax-compile-stall epic
+  (record complete/2026/08/jax-vmap-materialisation-hang.md, PyAutoFit#1528)
+- repos-none-claimed: no worktree claimed; investigation is CI-driven via retime.yml
+- why: #1528 shipped a WORKAROUND. Every JAX script in both test workspaces now runs
+  single-threaded Eigen (~15% slower on the heaviest), and that flag is load-bearing —
+  removing it silently brings back seven quarantines.
+- the recoverable-cost question: if XLA's pool is merely mis-sized against the runner's
+  cgroup quota rather than genuinely deadlocked, the fix is sizing it and the 15% comes back.
