Deployed this phase's frontend + AIUI to archi-dev-box (the dev pair;
x250-dev is currently offline via Tailscale, recorded rather than
silently skipped) via scripts/deploy-to-target.sh --frontend-only.
Verified the served bundle (not just local dist) contains this phase's
changes.
Then took a real on-device measurement instead of leaving the FA-D
KEEP_ALIVE_MAX estimate unexamined: a headless Chromium session on
archi-dev-box cycled all 11 main tabs through 4 full round-trips (44
navigations), reading the JS heap via CDP before/after each cycle.
Memory fluctuated 10-21MB with no monotonic growth across cycles that
each exceed the cap 10 distinct registered paths against KEEP_ALIVE_MAX=6.
Left the constant at 6, now backed by a recorded measurement.
