I don't think a FetchedSubscription should be considered successful if it returned a 404 (in that case, the subscription was not fetched successfully). I think we can make a was_not_found property (or similar) that we can check in conjunction with success to determine the full state.

That sounds like a good idea. I'll split this out to another PR, as I believe that not considering 404 a success will require some adaptations in other scenarios

| The DSS is in violation of **[astm.f3548.v21.DSS0005,1](../../../../../../requirements/astm/f3548/v21.md)**, as the implicit subscription does not cover the OIR's time boundaries; | ||
| Entities that should have been cleaned up earlier are still present in the DSS, and this scenario cannot proceed. |

We should be able to differentiate between these two causes, and the requirement not to have cleaned-up entities in the DSS should be identified. Presumably, this is the ClearArea requirement, and presumably that check was already performed when clearing the area (so we don't need to refer to it again here since we know it's not the cause since the earlier clearing succeeded).

PR for a scenario addressing implicit subscription handling, based on checks proposed in #415.
This depends on this DSS fix to be merged and released. The PR was tested locally against a fixed DSS and the scenario passes.
Some improvements that we could add in later PRs
Misc
force_no_implicit_subscriptionto theput_op_intentfunction in F3548'sdss.pyto allow callers to create an OIR without any implicit subscription (which is allowed for OIRs in the ACCEPTED state)This scenario covers the implicit cleanup fix on the DSS repo and covers some of the corner cases mentioned in interuss/dss#1088
