Meeting summary
---------------

* we are talking about need to reduce # of contracts per subject
  (dconde, 18:20:53)
* but what about based on flow?  (dconde, 18:21:01)
* that's doable with conditions! - says dvorkinista  (dconde, 18:21:09)
* if it's anomalous we can apply those to sites provided by said
  servers.  (dconde, 18:21:27)
* but mickey says" what is the def iof flow"  (dconde, 18:21:39)
* sanjay says "user X comm to wiki site A on HTTP" that flow is what
  Sanjay wants to apply security, improve experience, etc. but you want
  to do something different.  (dconde, 18:22:10)
* dvorkinista says you can mark them  (dconde, 18:22:21)
* but sanjay says that only subset needs to be set. classifiers vs.
  conditions is unclear  (dconde, 18:22:41)
* filters are HTTP -- only difference is actions says dvorkinista
  (dconde, 18:22:53)
* sanjays says what about on per-site  (dconde, 18:23:26)
* but if we have different sites, it's a different EPG -- says
  dvorkinista  (dconde, 18:23:39)
* info we can cover that in a clause.  (dconde, 18:24:07)
* functional equivalent thing are doable. not do it instance specific.
  (dconde, 18:24:23)
* we have a functonal way to achive that in current model with clauses,
  etc.  (dconde, 18:25:23)
* we are worried about proliferation of subjects - says Sanjar  (dconde,
  18:29:08)
* dvorkinista says we can intro containment within subject  (dconde,
  18:29:18)
* same classifiers and multiple ACTION sets  (dconde, 18:29:32)
* in the world of controls -- it's never in run time.  (dconde,
  18:31:45)
* there is an understanding of expected actions. nothing ins unplanned,
  says dvorkinista  (dconde, 18:32:13)
* this is in response to conditional labels or some other exception
  mechanism.  (dconde, 18:32:26)
* sajnay asks if we have lots of flows…then we…..  (dconde, 18:33:00)
* dvorkin says -- we can do anomaly detection per flow  (dconde,
  18:33:13)
* anjays wants to see how to get away from too many subjects per flow
  (dconde, 18:34:55)
* dvorkinista says it is not per flow.  (dconde, 18:35:15)
* we want to pre plan conditions to react consistently.  (dconde,
  18:35:31)
* dvorkinista parts of contracts can be mutated over time  (dconde,
  18:36:14)
* lenrow says if this is best practice for expected events -- that's OK
  (dconde, 18:36:26)
* dvorkinista says let's figure out planned stuff vs. dynamic stuff.
  (dconde, 18:36:59)
* do we want to extend concept of a session and piggy back on top of
  that.  (dconde, 18:37:38)
* sanjay asks how do we structure flows to KNOWN policies?  (dconde,
  18:38:50)
* dvorkinista semanticlly we can express is as for two EPs, each belong
  to an EPG, in context of a given contract, we need to overwrite a set
  of subjects. that's an exception.  (dconde, 18:39:32)
* we want to avoid a backdoor into this.  (dconde, 18:39:53)
* it's OK to have exception case (like using Asmbly for dev drivers)
  (dconde, 18:40:31)
* in the third option in yesterday's meeting, only thing we change are
  that there are not rules, but we put into filters of a subject.
  (dconde, 18:41:12)
* mickey -- how do we over ride or how to figure dyn add conditions,
  etc.  (dconde, 18:44:56)
* dconde asked whether we want these conditions to be as orthogonal a
  possible.  (dconde, 18:50:41)
* dvorkinista says yes  (dconde, 18:50:47)
* the conditions are planted by app owners  (dconde, 18:50:55)
* some form of melt-down that needs an exception to deal with anomaly.
  (dconde, 18:51:11)
* we cannot alter intent  (dconde, 18:51:38)
* we want to deal with exceptons without changing intent.  (dconde,
  18:51:55)
