Task 1.2: introduce a single path resolver so no harness script hardcodes `.specify/...` scattered across the tree. casan-paths.sh resolves four roots (HARNESS/STATE/GOVERNANCE/APP) by marker-based walk-up from its own location — never `git rev-parse` (git root is the repo PARENT here, not the app dir). - 101 bash scripts/tests: 238 hardcoded `$PROJECT_ROOT/.specify/...` refs rewritten to CASAN_HARNESS_ROOT (code) / CASAN_STATE_ROOT (logs,state) / CASAN_GOVERNANCE_ROOT. Sandbox test vars ($WORK/$TP/$FP/$T1_WORK) left untouched. - Roots are NOT exported: each script/subprocess self-resolves from its own tree, matching the original per-script semantics and preserving hermetic sandbox isolation (node casan-step.mjs, copied telemetry/rollback scripts must not inherit real roots). - Sandbox tests that copy a harness script now also copy casan-paths.sh (its new sibling dependency): adversarial (verify-audit-chain/verify-tool-audit/rollback) + track-a (security-check/telemetry-integrity). - control-plane-settings.json reclassified as STATE (untracked runtime store). Roots all still resolve to `.specify` in this monolithic layout, so behavior is unchanged. Full gate: PASS=64 FAIL=0 SKIP=3 (adversarial 44/0, track-a 25/0).

# 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, tenant, global}. A `global` switch stops
|
|
# everything; a `tenant` switch (SEC-23 MT-03) stops only that tenant.
|
|
# Env: CASAN_KILLSWITCH_DIR (default .specify/logs/level5/kill-switch)
