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 2 (MT-01) — per-tenant governance state isolation.
|
|
#
|
|
# The control-plane settings store (settings + its embedded audit hash-chain) and
|
|
# telemetry are now partitioned per tenant. Proves:
|
|
# * 23.5 a setting written by tenant A lands under A's partition; tenant B does
|
|
# NOT see it (separate store),
|
|
# * 23.4 the store (incl. its audit chain) is a distinct on-disk file per tenant,
|
|
# * cross-tenant guard denies B access to A's store path,
|
|
# * an invalid tenant id fails CLOSED in the control-plane tool,
|
|
# * 23.6 tenant-paths.sh resolves telemetry + CP paths under the tenant partition,
|
|
# and an explicit override still wins.
|
|
#
|
|
# Deterministic; hermetic (temp tenant-state root); no model/network.
