BE + supposed + to INFINITIVE

The B1 / B2 divide seems to have many clashing or repeated points when locating forms.   This post introduces another.   The B2 points 153 in the category of MODALITY “be supposed to” to talk about expectation or obligation, and point 130 also in MODALITY ” be supposed to’ to talk about hearsay or supposition clashes with point 121 at B1 ‘was supposed to’, ‘were supposed to’ to refer to past or future arrangements which may not have happened or may change, and point 99 B1 1 a limited range of expressions with ‘be’ + infinitive (‘be allowed to’, ‘be supposed to’, ‘be able to’) with present and past forms of ‘be’ and with modal ‘will’.

These examples from point 99 B1 seem like expectations at B2 or merely repeat B1 121 discussing arrangements which may not have happened:

I was supposed to be meeting my friend Laura but she didn’t come.

Definitions from google:

Supposition: a belief held without proof or certain knowledge; an assumption or hypothesis.

Here’s an example of B2 hearsay:
