- SEC-07 (M-08): real approval verification via approval-verify.sh in enforced mode (CASAN_PROFILE=prod / CASAN_APPROVAL_STRICT=1) for control-plane `set` (sensitive keys), kill-switch `clear`, and self-improve (inherits control-plane). A bare or forged approval string is now denied; dev mode stays backward-compatible. - SEC-10 (M-05): non-spoofable agent identity. tool-registry-gate least-privilege no longer trusts CASAN_AGENT env in enforced mode (CASAN_IDENTITY_STRICT=1) — the caller must present a signed token (agent-identity-sign.sh) bound to agent id + run id, verified against agent-identities.registry. Blocks env spoofing + replay. Verify: SEC+integrity gate 18/0, run-casan4 0-FAIL, adversarial 44/44 (H2 intact), control-plane 9/0, h5-approval 12/0, c7-incident 15/0, self-improve 7/0, track-c 29/0. Plan-16 P0 + P1 now complete; remaining: P2 (SEC-12/13/14/15/22..30). 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.
|
|
# Env: CASAN_KILLSWITCH_DIR (default .specify/logs/level5/kill-switch)
