- page_scenario.go: onclick built via JSON.stringify() embedded raw double
quotes inside a double-quoted HTML attribute, truncating the attribute so
the click handler never compiled; pass the name through an escaped
data-scenario-name attribute instead.
- build.sh: overlay staging rsyncs (OVERLAY_DIR->stage, stage->includes.chroot)
ran without --delete, so a scenario removed from the repo (a9924b0) stayed
baked into every ISO built from the persistent stage cache since — the
"second script" in the Scenario page's list.
- blackbox: rewritten around a deterministic local zip + incremental
patch-the-changed-suffix onto removable media, instead of walking/copying
~90 files through a synchronous ntfs-3g FUSE mount every cycle. journalctl
captures are now "--since last sync" (were "--since boot", growing with
uptime) and metrics.db is excluded (was copied whole every cycle).
- scenario: nvbandwidth-acs-ab now escalates GPU count (same-socket pair,
other socket's pair, one cross-socket pair, all GPUs) under each ACS state
instead of always running all 6 GPUs at once, using a new `bee
gpu-bandwidth-groups` subcommand that discovers socket layout from
`nvidia-smi topo -m` at runtime — gpu_indices is host-specific, so this
can't be baked into the scenario file.

Replaces the old nvbandwidth-all-gpu-power-watch scenario (dropped: the
power/IPMI-sampler framing was a dead-end — the blackbox shows every other
load test, incl. NCCL all-reduce across all 6 GPUs, passes with power fully
connected; only nvbandwidth on cross-socket GPU P2P reboots the box).
nvbandwidth-acs-ab is a two-phase reproduction for the MSI CG480-S6053 case.
Phase 1 disables PCIe ACS redirect at runtime via setpci (saving each
bridge's original ACS control word to /run/bee-acs-orig) then runs
nvbandwidth across all 6 GPUs — expected to survive. Phase 2 restores the
saved ACS values and repeats — expected to reproduce the reboot. Safe phase
first so its full blackbox reaches the USB stick before the risky phase can
reset the box (sync-bracket before the final job flushes phase-1 evidence).
ACS mutation runs via `bash -c` since scenario cmd is exec'd directly with no
shell. Both shipped copies (repo scenarios/ and image overlay) identical;
verified both parse via ParseScenarioJSON (4 jobs).
