Tasks

• Widen RequestContext.tenant to TenantContext | null in packages/api-stack/api/api-types/src/plugin-context/plugin-context.types.ts.
• Widen RequestContext.tenantId to TenantId | null at the same site.
• Add nullability rationale to the RequestContext TSDoc block — pointer to gap-5 + handler null-check guidance.
• Strip as never from tenant and tenantId assignments in packages/api-stack/api/api-host/src/request-pipeline/request-pipeline-helpers.ts.
• Replace capabilities/instruments as never casts with explicit as RequestContext["capabilities"] / as RequestContext["instruments"] plus a multi-line comment explaining the generic-erasure boundary.
• Audit handler-side consumers (apps/demo, apps/testbed, e2e/foundation-stack, api-plugin-*); confirm none dereference ctx.tenant.X without ?. and no code change needed.
• bunx turbo lint typecheck test build --filter=@suaveplan/api-types --filter=@suaveplan/api-host green.
• bunx turbo test:coverage --filter=@suaveplan/api-host --filter=@suaveplan/api-types green.
• cd e2e/foundation-stack && bunx playwright test — 11/11 green.
