utils/dev_acs_role_flip.sh:157
- Every DELETE response other than 404—including 401, 403, and 5xx—is treated as success, so
admin offcontinues and ultimately printsadmin OFFeven when no grant was removed. Accept only 2xx/404 and return nonzero for other statuses.
if [ "$code" = "404" ]; then
echo "revoke $1 grant $gid ($rest): already gone (404 - ACS read lag)"
else
echo "revoke $1 grant $gid ($rest): HTTP $code"
fi

In `@utils/dev_acs_role_flip.sh`:
- Line 50: Update the script before its SSM parameter access to call aws sts
get-caller-identity using the selected PROFILE, compare the returned account ID
with the approved development account ID, and exit immediately on mismatch;
preserve the existing AWS_PROFILE_OVERRIDE and default profile selection.
- Line 54: Update TOKEN_CACHE and the get_token flow to use a private mode-0700
directory under $XDG_RUNTIME_DIR or $HOME instead of shared /tmp. Write the
token to a uniquely created temporary file within that directory, then
atomically rename it to TOKEN_CACHE, preserving secure permissions and avoiding
predictable symlink-following writes.
- Line 65: Update mint_token so the M2M client secret is not interpolated into
curl arguments: build the grant payload with a JSON encoder to correctly escape
credential values, then pipe the encoded JSON to curl using --data-binary `@-`.
Preserve the existing token request behavior while removing secret exposure
through process inspection.
- Around line 153-157: Update do_revoke to return nonzero for every revocation
HTTP status except the documented successful deletion status and intentional 404
response, while preserving the existing logging. Ensure the admin off flow
propagates do_revoke or wait_admin_state failure instead of printing admin OFF
and exiting successfully.
- Around line 170-171: Update the admin-state result and the equivalent status
condition to use only the system-admin role for the Warden isAdmin=true outcome.
Keep lf-staff as a separate consistency indicator and remove it from the
system-admin OR condition, including the logic consumed by wait_admin_state.

the TOKEN_CACHE freshness/return condition, so every token retrieval validates
the target AWS account, including cache hits.

- This cache duration conflicts with the repository's documented ACS warden TTL of about 30 minutes (
docs/MY_CLAS_API.md:95anddocs/easycla-ss-migration/role-mapping-feasibility.md:93). Understating it as 10 minutes can make role-flip tests rely on stale authorization for another 20 minutes.
This issue also appears on line 237 of the same file.
utils/dev_acs_role_flip.sh:237
- The status output repeats the incorrect 10-minute cache window; the documented ACS warden TTL is about 30 minutes, so users may otherwise resume testing while the old authorization is still cached.
echo "note: gateway/warden may serve cached answers for up to ~10 min; use -H 'Cache-Control: no-cache' on API calls"

- The “restored losslessly” guarantee is not implemented.
admin offdiscards both grants, whileadmin onalways creates both canonical grants without recording whether either role existed beforehand, so an off/on round trip can change a user's original role set. Either persist and restore the prior grants, or document thatadmin onestablishes a fixed two-role state rather than restoring it.
This issue also appears in the following locations of the same file:
- line 19
- line 237

- This understates the cache window: the repository's verified ACS notes document a ~30-minute warden authorize-response cache (
docs/easycla-ss-migration/role-mapping-feasibility.md:88-94). A 10-minute claim can cause operators to misdiagnose expected stale authorization after a role change.
# - warden caches successful (user,resource) answers for ~10 minutes; the
utils/dev_acs_role_flip.sh:237
- Update this operator-facing status note to the documented ~30-minute warden cache duration; otherwise it repeats the misleading 10-minute expectation even if the header comment is corrected.
echo "note: gateway/warden may serve cached answers for up to ~10 min; use -H 'Cache-Control: no-cache' on API calls"
