Summary

This branch adds defense-in-depth economy validation at contract issue time: ContractEconomyValidation.TryValidateTemplate delegates to existing PrototypeE7M4ContractCatalogRules band-cap and cross-ref helpers, wired into ContractGeneratorOperations.TryIssue after template selection and before persist. Two new reason codes (economy_cap_exceeded, invalid_reward_bundle) surface stable deny semantics for downstream HTTP (NEO-151) and client copy (NEO-153).

The implementation matches the adopted kickoff plan: registry parameters on TryIssue, split reason codes, full loader-parity cross-ref scope, and no HTTP/client scope creep. All TryIssue call sites are updated; unit and integration tests cover happy path, over-cap deny, and unknown bundle ref deny. Full suite passes (911 tests). Risk is low — logic reuses proven CI/startup gates; main residual risk is per-issue registry snapshot allocation cost, acceptable at prototype scale.

Suggestions

  1. Deduplicate prototype registry test fixturesContractEconomyValidationTests.CreatePrototypeRegistries() and ContractGeneratorOperationsTests.CreatePrototypeCatalogRegistries() are nearly identical (~50 lines). Consider a shared internal test helper (e.g. ContractPrototypeTestFixtures) to avoid drift when prototype catalog ids change. Done.ContractPrototypeTestFixtures.CreateCatalogRegistries().

  2. Broaden deny-path test matrix (optional) — Current tests exercise item qty over cap and unknown item id only. Band-cap and cross-ref helpers also cover skill XP, reputation grants, unknown encounter, and disallowed mission_reward skill sources (covered at loader level in ContractTemplateCatalogLoaderTests). One additional [Theory] or a skill-Xp-over-cap case in ContractEconomyValidationTests would document parity without much cost. Done.TryValidateTemplate_ShouldDenyEconomyCapExceeded_WhenSkillXpOverBandCap.

  3. NEO-151 call-site checklist — When HTTP lands, confirm the production DI path passes the same four registries already wired in integration tests. No code change needed here; worth a one-line note in NEO-151 plan. Done. — handoff row in NEO-150 plan open questions (pending for NEO-151 kickoff).

Nits

  • Nit: ContractEconomyValidation.TryValidateTemplate does not null-check template; safe today because TrySelectTemplate only returns success with a non-null template, but ArgumentNullException.ThrowIfNull(template) would mirror the registry guards. Done.
  • Nit: Issue-time validation order is band-cap → cross-ref; startup loader runs cross-ref → band-cap. Intentional per plan (cap failures get economy_cap_exceeded), but worth keeping in mind if both gates ever fail on the same row during debugging. Done. — inline comment in ContractEconomyValidation.
  • Nit: Per-issue allocation of encounter/faction hash sets and skill dictionary is fine for prototype; revisit only if issue volume becomes hot-path.

Verification

Commands run during review:

dotnet test NeonSprawl.sln --filter "FullyQualifiedName~ContractEconomyValidation|FullyQualifiedName~ContractGeneratorOperations"
dotnet test NeonSprawl.sln

Results: 20 filtered tests passed; 911/911 full suite passed.

Author pre-merge checklist:

  • dotnet test NeonSprawl.sln green
  • Merge to main and proceed to NEO-151 (HTTP) with extended TryIssue signature
  • No Godot manual QA required (server policy per plan)
