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-14 — RBAC decision audit into an H5-style oversight log.
|
|
#
|
|
# Every RBAC allow/deny decision is recorded (opt-in via CASAN_RBAC_AUDIT_LOG) so a
|
|
# reviewer / RAI report / Control Plane can see who was allowed or denied what and
|
|
# why. Proves:
|
|
# * an ALLOW decision is logged with verdict + role + action,
|
|
# * a DENY decision is appended (append-only) with its reason,
|
|
# * a cross-tenant DENY records the tenant-boundary reason,
|
|
# * with no audit-log env set, nothing is written (backward compatible).
|
|
#

# Deterministic; hermetic; no model/network.
