4_Blanton_Script_thermal_safety.ttl brings the DUT up the way Script A
does, then loads it - mlucas-avx2 -cpu 0:15 in the background plus
blanton_tr518.sh start - and samples platform data and both switch
boards' rail power every minute. Power per rail under sustained full
load, over hours, is the whole point of it.
It is standalone: nothing starts it, it starts nothing, and it must not
share a DUT with Script B because both take over the cd ports.
It also has no teardown. When you interrupt it the unit is still in
port cd lb=mac / l2 learn off / test mode nr=yes and mlucas is still
running, and show interfaces status does not reveal any of that. Called
out in the version history, the release notes, CLAUDE.md gotchas and the
ARCHITECTURE future-work list, because whoever uses the box next will not
find out on their own.
Script B's per-round loop drops the margin scan. The loop is meant to be
a quick minute-by-minute sample and margin_status_all.sh walks nine
LTC2980s over I2C, which dominated the round. Script C takes it instead,
once, before show uptime. The trade-off is real: margin drift DURING the
soak is no longer visible, only a start and an end reading. Documented
rather than glossed over, with a suggestion (scan every N rounds) if it
needs to come back.
Script C also sends exit and waits for "Script done" before
hw-test-session finish, so finish runs in the login shell rather than
inside the session it is closing.
Adds docs/Blanton_Test_Flow.drawio: all four scripts side by side, with
the config flags that change each step marked, Script B's one real goto
drawn, and the A->B->C handoffs shown as the manual steps they are.
The new script arrived LF-only while every other .ttl is CRLF and
.gitattributes marks *.ttl as -text, so what is committed is exactly what
Tera Term reads. Converted.
Script A -> V1.1.4.
