…TryCreateUsage Companion to JasperFx/jasperfx#431 — populates the new descriptor fields on `EventStoreUsage` from `StoreOptions.Projections.Errors` and `.RebuildErrors` in `DocumentStore.EventStore.TryCreateUsage`. With these on the wire, downstream monitoring tools (CritterWatch) can render the projection-error policy operators have actually configured and pick the right affordance — DLQ inspection vs "shard halts on error" indicator. Motivated by JasperFx/ProductSupport#3: a Marten consumer running with `Projections.Errors.SkipApplyErrors = false` (stop-on-error policy) was shown a "View Related Dead Letters" button on the projection detail page, because CritterWatch had no way to read the policy off the wire and assumed skip-and-DLQ behaviour. Three flags carry over for each of normal-run and rebuild-mode: - `SkipApplyErrors` - `SkipUnknownEvents` - `SkipSerializationErrors` `ProjectionRebuildErrors` is populated independently of `ProjectionErrors` because rebuilds default to stop-on-error even when normal runs skip — operators rebuilding need to know whether a poison-pill event will halt the rebuild. CoreTests pin the new shape via a stop-on-error config: a host with `Projections.Errors.SkipApplyErrors = false` shows up correctly in the descriptor, and the (unchanged) rebuild defaults round-trip too.

ErrorHandlingOptions's three flags:SkipApplyErrors,SkipUnknownEvents,SkipSerializationErrors.Why
JasperFx/ProductSupport#3 — a Marten consumer running with
Projections.Errors.SkipApplyErrors = false(stop-on-error policy) was shown a "View Related Dead Letters" button on CritterWatch's projection detail page because CritterWatch had no way to read the policy off the wire and assumed skip-and-DLQ behavior. With this PR (after #431 ships) CritterWatch will be able to render the right affordance per store.Coordination

CoreTests/jasper_fx_mechanics.cstest exercises a stop-on-error config end-to-end and asserts both descriptors carry the right values. Passes locally against a local-feed prerelease of JasperFx.Events with the descriptor types in place.🤖 Generated with Claude Code
