Spirevault: Ascend the Castle First Launch Foundation Sprint 01

Spirevault now has a verified first-launch foundation for CH01 Silvergate Ascent.

Spirevault: Ascend the Castle now has its Sprint 01 first-launch foundation on main.

The sprint converts CH01 Silvergate Ascent from source design evidence into executable production material: VeritySpec records, structured content data, deterministic validation, C# runtime contracts, roadmap updates, tests, and an evidence ledger.

The first-launch contract covers twelve authored onboarding floors, the first-floor clear, repeated-failure hinting, a full-spire perfect-banner path, assisted/unranked state, local progress, settings, support, privacy, restore visibility, and explicit no-service guardrails.

The merged game PR is Jason-Furr/spirevault-ascend-the-castle#4, closing issue #3 with merge commit d74520a. Main checks passed for CI 28610393156, Content Validation 28610393568, VeritySpec 28610393022, and CodeQL 28610400960.

This is not a release or store-readiness claim. Unity scene construction, controller physics, device QA, ads, purchases, analytics, telemetry, cloud save, accounts, leaderboards, and release publishing remain future or owner-approved work.
