gVisor replays exhausted the hook's 30 s deadline in the snapshot step on a
1,725-file repository; cluster replays now use 30 s x a measured slowdown
factor, verified on a native sample. The engine runner deletes each pin's fetched
source (1.8 GB had accumulated), caps the cache at 500 MB and refuses below
1.5 GB free. Proof 4.4: two engine pins via the generic dispatcher match the VM
baseline exactly. Implemented with Codex.

Implemented with Codex; task 1.5 run by the coordinator against the real
sources (S3 memory read-only).

Decisions: long-deadline arm (300 s), adoption needs no unseen regression
(Req 5.4), permissive repositories by name only, two AX lanes. Also adds the
trained-classifier and joint-optimisation arms to learned-decision-engine.

Maintainer 2026-10-04: the safety net is for unseen code and the A/B tests exist
to prove the approach generalises; infrastructure work had drifted from that.
Runs are designed for AX on kube-ax, kind is the fallback.
