Mirror validate_content.py gates in MasteryCatalogLoader, expose IMasteryCatalogRegistry, cross-check skillIds against the skill catalog, and enforce tierIndex 1..N per track.
Register SkillDefinitionCatalog from content/skills with JsonSchema.Net validation
mirroring validate_content.py and the prototype Slice 1 gate. Resolve paths via
Content:SkillsDirectory or discovery from AppContext.BaseDirectory. Eager-load
after WebApplication build so bad catalogs block startup. Add unit and host
tests, pin test factories to repo skills, document config in server/README, add
manual QA checklist, and extend Bruno GET /health smoke tests.
Ship a server-owned hotbar loadout API with Postgres-or-memory persistence so slot bindings survive reconnects in configured environments. Wire client boot hydration and add tests/docs/manual QA to keep the prototype contract and policy explicit.
Wire IPositionStateStore to Npgsql when ConnectionStrings:NeonSprawl is set,
with versioned DDL under server/db/migrations and a shared PostgresPositionBootstrap
for schema plus dev-player seeding at host startup. In-memory tests override Postgres
registrations when CI sets the connection string globally.
Add GitHub Actions Postgres service for dotnet test, server README updates,
decomposition and implementation-plan docs, code review write-up, and C# brace
conventions in csharp-style rule.
