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 Plan-16 SEC-23 Phase 1 (MT-01) — tenant-partitioned state store + guard.
|
|
#
|
|
# Proves:
|
|
# * 23.1 two tenants resolve to DIFFERENT partitioned paths; an invalid/traversal
|
|
# tenant id or logical name is rejected,
|
|
# * 23.2 cross-tenant guard: tenant A cannot access tenant B's path (DENY), but its
|
|
# own path is allowed,
|
|
# * 23.3 the tenant root is created 0700 (owner-only),
|
|
# * 23.12 secure-by-default: prod with no CASAN_TENANT_ID fails CLOSED; dev falls
|
|
# back to a 'default' tenant; prod WITH a tenant is fine.
|
|
#
|
|
# Deterministic; hermetic (temp tenant-state root); no model/network.
