e2f59b2e26 specify how to reenable padding 
Arti has a "dormant mode" which means that it might need to reenable
channel padding after hving disabled it.

How to do this, paarticularly in the face of possibly changing
consensus parameters, is an edge case.

1272bd0db5 Describe a potential (rare) distringuisher in idle circuits. 
In the rare event that a user resumes activity after a period between the
"reduced connection timeout" and the full value, and that user has not set
reduced padding, this is a distinguisher on circuits that have been held idle
and open for that long.

5536d29700 Padding spec: describe behavior with queues. 
(Briefly: "Sent" is sometimes unobservable, so we should use

e35a770882 netflow padding: clarify directionality and padding behavior. 
The main points here are:

  * We assume that flow measurements are unidirectional, so
    each side must make sure to send traffic.
  * So we restart our timer when sending, only.
  * We restart the timer whether we're sending real traffic or
    padding traffic.
  * The logic for `max(X,X)` timing  applies even though we aren't
    using a bidirectional trigger for timing.

71c326ae93 Prop 324: Updates for Negotiation and Simulation Testing 
Changes:
  - Rework exit negotiation logic a bit
  - Specify using ntorv3 with extension fields for negotiation
  - Clients only request congestion control; exits and services
    control sendme_inc
  - Rework onion service negotiation for descriptor-controlled
    FlowCtrl protover and sendme_inc value
  - Add bounds checks on sendme_inc for clients
  - Update parameter values based on Shadow results
  - Improvements to TOR_VEGAS algorithm based on simulation testing
  - Additional consensus parameters for RTT N-EWMA smoothing and
    TOR_VEGAS queue use caps
  - Clarify N_EWMA smoothing, and relocate it to its own sub-section.
  - TOR_VEGAS now defaults to CWND/RTT BDP estimator
  - Minor TOR_VEGAS alg bugfixes
  - Add a 'delta' parameter to TOR_VEGAS for steady-state backoff
  - Consensus param update notes and param range fixes.
  - Add glossary of common congestion control acronyms
  - Misc clarifications
