[AW Top 10] 07 Replace compile-path panics with returned errors #65485

Priority 7/10 | 4 source issues | Impact 3/5 | Confidence 4/5 | Effort 2/5

One assignment, one coherent fix

Compile-path code panics on invariant failures in domains, cache-memory and related validation instead of returning errors.

Implementation scope

Convert the cited panics to returned errors, add a per-workflow recover boundary in the compile loop, and tighten the related validation paths.

Done when

• An invalid cache-memory ID returns an error instead of panicking.
• A panic inside one workflow compile is recovered and reported without aborting other workflows.

Why now

Four related DeepReport findings target compile-path code, and a single panic can abort compilation of every workflow.
