mlucas-avx2 was backgrounded with '&' in the login shell, so it belonged
to that one terminal. Close Tera Term, drop the console, or reconnect on
a different session and the load was gone - and 'jobs' from the new
session showed nothing to say so. A multi-day soak could spend most of
its length with an idle CPU while the thermal numbers looked fine.
Script B now starts it as a transient unit:
systemd-run --unit=mlucas-amm --property=Type=exec \
--property=Restart=always --property=RestartSec=2 ...
The log is truncated once with '>' before the unit starts and appended
with '>>' inside it, so a restart adds to the run instead of erasing it.
'systemctl is-active mlucas-amm' now sits beside 'jobs', both in the
one-shot check and in every pass of the monitor loop. The old '&' line is
kept commented out above the new one to fall back to.
Script C has the matching stop. utils/kill_all_process.ttl is only
"kill $(jobs -p)" and a systemd unit is not a shell job, so without this
the load would have run through the post-test snapshot and into the next
test - every temperature and power reading taken at full load, with
nothing in 'show interfaces status' to reveal it. mlucas_amm_log is
copied to /host/hw-eval/jobs/ with the other stress logs.
Two values move into config.ttl:
EN_timestamp feeds logopen's 5th argument in Script A, so the
per-line timestamp is a knob rather than a literal 1
BMC_USB_RUNTIME feeds Script B's ping unit; it was hard-coded to
-w 14400 (4 h), which no longer matched the soak
lengths the SSD and USB knobs were being set to
SSD_RUNTIME and USB_RUNTIME also go 600 -> 3600, so the shipped default
is a one hour stress rather than the ten minutes V1.1.7 went out with.
--runtime is still the job's overall limit; COUNT does not multiply it.
Script A's Version History carries the V1.1.8 entries for all of this.

SSD_RUNTIME / SSD_COUNT and USB_RUNTIME / USB_COUNT replace the values that
were hard-coded in Script B, so a site changes them in one place. COUNT is
passed straight through as --passes.
--runtime is the job's OVERALL limit, not a per-pass one: qfx5252-stress-*
stops after RUNTIME seconds whatever --passes says. RUNTIME 600 is a ten
minute stress, not 600 x COUNT. A 24 hour soak needs RUNTIME 86400.
Also restore timeout = 0 on the cdc_ncm success path. It was restored only at
:skip_ping, which the success path reaches several waits later - until then
every wait gave up after 15 s instead of blocking, and a wait that returns
without eating the prompt puts the macro a beat ahead of the DUT.

FAN_SPEED 30 -> 100. A soak is a thermal test of everything except the
cooling, so the cooling should not be one of the variables in it. At 30%
a long run can throttle partway through, and throttled results read like
a different fault entirely.
Folded into V1.0.11 rather than bumping the version: the tag has not
moved on and this is the same delivery.

config.ttl gains FAN_SPEED (30). Script A rebinds the two max31790
controllers (18-0020, 25-0020) and applies the speed with
fan-speed-control.sh, answering its confirmation prompt, so a run starts
from a known thermal state rather than whatever the last test left.
Script A also clears /host/hw-eval/current/jobs before the run, and
Script C copies that directory to /mnt/usb/jobs-<date>_<time> so the
bgctl job logs leave the DUT with the run they belong to.
Fix: 25-0020 was bound twice in a row -- the second bind can only fail,
since the driver is already attached. Removed; the two controllers now
have a matching unbind/sleep/bind each.
Script A -> V1.0.7, history covering the config.ttl and Script C changes
as well.
Docs: fan control and the job-log archive added to Tech Stack, Key
Features and Data Flow; the config.ttl example refreshed with FAN_SPEED
and the SWB_UNIT flags. Three risks recorded in Future Extensions --
`rm` without -r cannot clear the job subdirectories that Script C copies
with -r, the fan confirmation wait has no timeout and would hang
silently if the prompt ever changes, and /mnt/usb is never checked for
being mounted.

Rework the traffic blocks in A, B and C as explicit if/elseif branches
holding literal commands, and drop the derived swb_any/swb_opt from
config.ttl -- the branches read straight off the page and there is no
indirection to follow.
All nine conditions compared SWB_UNIT0 against itself, though:
if SWB_UNIT0 = 1 && SWB_UNIT0 = 1 -> SWB_UNIT0 = 1
elseif SWB_UNIT0 = 1 && SWB_UNIT0 = 0 -> never
elseif SWB_UNIT0 = 0 && SWB_UNIT0 = 1 -> never
so the single-unit paths were unreachable. A DUT with only unit 0 would
have run the both-unit commands and hit bcmcmd on an absent unit 1,
while a DUT with only unit 1 fell through to the empty else and skipped
traffic entirely. Second operand is now SWB_UNIT1.
Verified per branch that the -u argument matches the condition guarding
it: both units carry no -u (tool default TL_UNITS="0 1"), unit-0-only
carries -u 0, unit-1-only carries -u 1, and the else stays empty.

The bench is not always fully populated. config.ttl now declares which
switch units exist:
SWB_UNIT0 = 1 ; this DUT has switch unit 0
SWB_UNIT1 = 1 ; this DUT has switch unit 1
Two values are derived there rather than repeating the same test in
three scripts: swb_any (0 = no unit at all) and swb_opt, the suffix
appended to each blanton_traffic_linespeed call -- "" for both units so
the tool's own TL_UNITS="0 1" applies, " -u 0" or " -u 1" for a single
one.
Script A, B and C build their traffic commands with sprintf2 and the
suffix, wrapped in `if swb_any = 1`. A half-populated DUT no longer
issues bcmcmd against an absent unit, and a DUT with no switch board
skips the traffic stage outright instead of filling the log with
failures.
wait_init.ttl reads the same two flags instead of its own copies, so the
wait and the traffic blocks cannot disagree about what is installed.
Script A -> V1.0.5.

publish/publish.sh packages src/Script_ABC_Blanton into
publish/Script_ABC_Blanton_<Ver>/, with -z for a zip, -f to overwrite,
-n for a dry run.
The version is read from Script A's "; Version :" header rather than
passed in, so the folder name cannot disagree with what the tester sees
on opening the macro. The header is CRLF, so the carriage return is
stripped -- left in, it becomes part of the directory name. Captured
logs are excluded (they carry DUT serials) but the empty logs/ is kept
because logopen writes there. .gitignore now admits the tool while
still ignoring its output.
config.ttl: testcase ENV, margin scan off for this run.
Docs brought up to date with the 14 commits since 8aa5c90 -- SWB
channel/address map, the traffic and BMC tooling, line-ending policy,
and the exec-bit and tail -f traps.

Bring the Blanton Tera Term TTL test suite under version control and
document how the pieces fit together.
- ARCHITECTURE.md: A/B/C script roles, host-to-DUT-to-FPGA data path,
config/settings/profile data models, PCIe AER + EDAC topology table,
10 key constraints, and 6 development phases derived from the
Status_20260814 spreadsheet's On-Going items
- CLAUDE.md: stack, smoke-test commands, conventions, and the hardware
footguns (per-unit BDF, VSPI vs VI2C timing, repeated START,
STORE_USER_ALL, ARB_LOST false positives)
- secret/: gitignored credential store with README + .example template,
so the DUT login stops living in 1_Blanton_Script_A.ttl
- .gitignore: secret/*, For_AI/, *.log, publish/, *.DSN
