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 (MT-01) — tenant-partitioned state store + cross-tenant guard.
|
|
#
|
|
# Harness state (audit chains, control-plane settings, telemetry, logs, kill-switch)
|
|
# used to live in SHARED global files, so a run for tenant A could read/modify
|
|
# tenant B's state directly — bypassing RBAC (which only guarded the API, not the
|
|
# files). This resolves every state path under a per-tenant root and refuses any
|
|
# access that escapes the caller's own tenant partition (reusing the SEC-28 realpath
|
|
# guard). Deny-by-default; secure-by-default in prod (missing tenant = fail-closed).
|
|
#
|
|
# Tenant id: CASAN_TENANT_ID (allowlist [A-Za-z0-9_-]+, no path traversal). Unset →
|
|
# 'default' in dev, but REFUSED under CASAN_PROFILE=prod.
|
|
#
|
|
# Usage:
|
|
# tenant-store.sh id # print resolved tenant id
|
|
# tenant-store.sh root # print this tenant's state root (0700)
|
|
# tenant-store.sh init # create tenant root with 0700 perms
|
|
# tenant-store.sh resolve <logical-name> # print tenant-scoped path for a state file
|
|
# tenant-store.sh guard <path> # exit 0 if path is inside own tenant root, else DENY
|
|
# Env: CASAN_TENANT_STATE_ROOT (default .specify/state/tenants)
|
|
# Exit: 0 ok · 3 denied (reason on stderr) · 64 usage.
