Hi.

I checked the following points.

1.  I ran and checked raw output in JSON 
   (which is at did-test-suite/packages/did-core-test-server/report/tmp/did-spec-test-run.latest.json  this file is gitignore'ed)

Only three outputs for the following statement:

> 7.1.3 DID Document Metadata - If a DID has been deactivated, DID document metadata MUST include this property with the boolean value true.

These are following three DIDs:
         did:btcr:x705-jznz-q3nl-srs
         did:btcr:xz35-jznz-q9yu-ply
         did:orb:interim:EiDQF58KdqxovQinUrhplB8P83_F8aMP7tTwLD6UrgVzNA

One test output for the following statement:

> 7.1.3 DID Document Metadata - If a DID has not been deactivated, this property is OPTIONAL, but if included, MUST have the boolean value false.

This is for this DID:  did:btcr:xkrn-xz7q-qsye-28p

Thus, I believe this is not a tallying code problem.


2. Markus listed following files:
> https://github.com/w3c/did-test-suite/blob/main/packages/did-core-test-server/suites/implementations/universal-resolver-did-btcr.json
> https://github.com/w3c/did-test-suite/blob/main/packages/did-core-test-server/suites/implementations/resolver-did-ion.json
> https://github.com/w3c/did-test-suite/blob/main/packages/did-core-test-server/suites/implementations/resolver-did-orb.json

Since `resolver-did-on.json` is in `brokenFixtures`, this one will not appear in test results.

So I think test output and report are in sync.


3. Before checking the above conditions, I set several breakpoints to observe the situation.
    At least, I found the following possibly incorrect values
   (I'm not reading this part of the code well. so I might be wrong)

   - `testDidDocumentMetadata`  may ran empty `didDocumentMetadata`
   - expectedOutcome can be `defaultOutcome` but code checks against with
     equal to `activatedOutcome` or `deactivatedOutcome`
    -> https://github.com/w3c/did-test-suite/blob/992369bda6fd78314a4bae7f969e0a5fb11dbb2f/packages/did-core-test-server/suites/did-resolution/did-resolution.js#L203

Hope this helps.
