Codex found two problems and I agree with both: (1) the hit path as I drew it was wrong. Dispatch still needs the payload, so attempts 2..N still fetch it; the cache saves only the graph walk. (2) There is no baseline; nobody has measured what the walk costs versus the fetch. I am explicitly reversing my earlier recommendation.\nELI10: I claimed the cache would let retries skip the expensive database read. It cannot, because the retry still needs the payload to do its job. What it skips is the loop over the payload that builds the dependency graph, and nobody knows if that loop is slow. Adding stored state, an invalidation rule and tests for a win nobody has measured is the kind of premature optimization the plan review is supposed to catch. Recomputing is boring and correct; measure it, then cache if the numbers say so.\nStakes if we pick wrong: keeping 6A adds a stored blob, an invalidation rule and concurrency questions to a retry PR for an unmeasured benefit; reverting means retries pay the full graph walk until someone measures, which with 2A's bound is a small, known cost.\nRecommendation: 9A (revert to recompute, measure first, cache as a TODO with a numeric trigger) because the corrected analysis removed the main benefit I cited, and boring by default wins when the win is unmeasured. Maps to engineered enough, not over-engineered.\nNote: options differ in kind, not coverage — no completeness score.\nNet: an unmeasured optimization with real state-management cost vs a measurement task and a TODO that fires on evidence."

Without a cap, attempt 12 waits over an hour. Without jitter (a small random spread), every job that failed in the same outage retries at the exact same instant and re-creates the spike that broke things. Both are one-line additions to the delay function you already own under 1A.\nStakes if we pick wrong: A downstream blip fails hundreds of jobs at once; they all retry in lockstep and knock it over again, repeatedly.\nRecommendation: 4A because jitter and a cap are the standard shape of this function and cost nothing extra with the library doing the scheduling. Maps to your \"handle more edge cases\" preference.\nCompleteness: 4A=10/10, 4B=7/10, 4C=4/10\nNet: Two named constants and a random factor now versus a thundering-herd incident later."

Codex raises two points. First, a version tag does not notice if the inputs the graph was built from changed, so the retry could run against a graph that no longer matches its inputs. Second, nobody has measured how expensive the rebuild is, so the cache may be solving a cost that does not exist. Stronger invalidation means also storing a hash of the payload snapshot the graph came from and rebuilding when the hash differs.\nStakes if we pick wrong: Either a retry executes an inconsistent graph (wrong work, hard to debug), or you build and maintain a cache for a rebuild that costs milliseconds.\nRecommendation: 15B because the plan itself gives no rebuild cost, the persisted graph adds a correctness surface Codex is right about, and one timing metric turns this into a data-driven follow-up.
