Closes the last fully-[planned] Track-C dimension (was scored 1). - incident.sh raise <event>: classify severity via incident-severity.map (LOW/MED/HIGH/CRIT), record a structured entry (owner routing), and for HIGH/CRIT auto-engage the scoped kill-switch + dispatch an alert (reuses H6 alert-dispatch.sh). Exit 2 on HIGH/CRIT so a pipeline gate goes red. - kill-switch.sh engage/clear/check/status, scoped by project/model/provider (+ global). `check` exits 2 when engaged so gates honor it. - casan-harness.sh honors an engaged kill-switch before running (opt-in CASAN_KILLSWITCH_ENFORCE=1, default OFF → baseline unchanged). - incident-runbook.md: severity→owner→response + postmortem template + prod TODO. - phase-c7-incident-tests.sh: 15 checks — severity grading, auto kill-switch on HIGH/CRIT, MED-only records, lifecycle, global scope, structured record, and the production wrapper refusing to run under an engaged switch. Baselines: run-casan4 35/35, adversarial 44/44. New suite total: 175 → 190. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# CASAN H6/H7 — Kill-switch (Incident response · C7 / V23).
|
|
#
|
|
# A scoped emergency stop: engage a switch for a project / model / provider and
|
|
# any gate that honors it refuses to run further work in that scope. Engaging is
|
|
# recorded; clearing requires an explicit reason (production: reviewer approval).
|
|
#
|
|
# Usage:
|
|
# kill-switch.sh engage <scope> <id> [reason] # turn the switch ON
|
|
# kill-switch.sh clear <scope> <id> [reason] # turn it OFF (audited)
|
|
# kill-switch.sh check <scope> <id> # exit 2 if engaged, 0 if clear
|
|
# kill-switch.sh status # list engaged switches
|
|
# scope ∈ {project, model, provider, global}. A `global` switch stops everything.
