Does /dev/pps0 exist?
Does /sys/devices/virtual/pps/pps0 exist?
Do either the assert or clear files in that directory exist and do they
display steadily increasing values in the file (looket at at successive
times)?
It would really help the reader if you made some indication as to where a new
file were listed in your dump of various files. Just the name of the file is
not enough.

I've had chrony 2.3 running on jessie with PPS, but haven't been able to get
PPS working on stretch with chrony 3.0. Here is my configuration on stretch
(which was the same on jessie):
refclock PPS /dev/pps0 lock NMEA refid PPS
# Settings for 1 update per 1 to 2.5 second seconds
#refclock SHM 0 offset 0.5 delay 0.2 refid NMEA noselect
# Setting for 2, 3, 4, 5, 10 updates per seconds
refclock SHM 0 offset 0.1 delay 0.2 refid NMEA noselect
What feeds the SHM with the NMEA time? Are you also running gpsd?
What is in the chrony logs (actually you should turn them on)
