folks - above IS accurate
there is no reason for guessing or contradicting
a PDF of the CBA is available on line

here is the relevant section
13.5 Waiver Expiration.
The rights granted under this Article to Loan a Player(s) who is
otherwise required to clear Regular Waivers to a minor league club expire for any Player(s) who,after clearing Regular Waivers:
(i) is not Loaned to a minor league club, or is Recalled from a minor league
club (except on emergency Recall) and remains on an NHL roster for thirty (30) days (cumulative) or plays ten (10) NHL Games (cumulative),
or
(ii) is Recalled from a minor league club on emergency Recall and plays in
ten (10) NHL Games (cumulative) while on emergency Recall. For
purposes of clarity, games played while on regular Recall shall not count
towards the ten (10) NHL Games in this subsection (ii).
so Hrivik, Jensen, Bodie, Fontaine, Brown, Glass, Summers, can come up, and go down, without issue until he plays 10 games or stays 30 days
