-# Index Backend Repro (Isolated)
+# Index Backend Verification (Isolated)
 
 ## Summary
 
-With a fresh store root, `amduatd` on `--store-backend index` accepts the first
-`/v2/graph/nodes` write, then fails on the second node write with `{"error":"store error"}`.
-The same call sequence succeeds on `--store-backend fs`.
+The previously reported isolated index-backend write failure is not reproducing on
+current builds.
 
-Observed daemon log on index:
+Verified on **2026-02-08** with a fresh store root:
 
-```text
-ERROR: edge append failed for space/app1/daemon/edges (err=2)

-Expected: both nodes + edge succeed.
-Actual on index: second node returns `{"error":"store error"}`, edge returns `{"error":"object not found"}`.
+Expected: all three requests return HTTP 200.
 
 ### 3) Control check (fs backend)
 
-Run the same payloads against fs:
-
 ```bash
 STORE_BACKEND=fs STORE_ROOT=/tmp/amduat-asl-fs-iso \
 SOCK=/tmp/amduatd-fs-iso.sock SPACE=app1 \
 ./scripts/dev_start_daemon.sh
 ```
 
-All three calls succeed on `fs`.
+Run the same three API calls. Expected: HTTP 200 for all calls.
 
-## Likely Failure Path
+## Regression Gate Recommendation
 
-From source:
+Use these as quick confidence checks when updating `vendor/amduat-api`:
 
-- `vendor/amduat-api/src/amduatd_concepts.c`
-  - edge append path calls `amduat_asl_collection_append(...)`
-- `vendor/amduat-api/vendor/amduat/src/core/asl_collection.c`
-  - `AMDUAT_ASL_COLLECTION_ERR_IO` comes from `amduat_asl_log_append(...)` failure
-- `vendor/amduat-api/vendor/amduat/src/core/asl_log_store.c`
-  - failure likely in pointer/log append path (`pointer_get`, `store_get`, or `pointer_cas`)
-
-## Targeted Upstream Patch Path
-
-1. Add temporary diagnostic logging in `amduat_asl_log_append(...)` for:
-   - `pointer_name`
-   - `ptr_err` from `amduat_asl_pointer_get`
-   - `store_err` from `amduat_asl_store_get` / `amduat_asl_store_put`
-   - `cas_err` and retry exhaustion path
-2. Re-run the minimal repro above and capture the first non-OK internal return.
-3. Patch the specific failing branch in `asl_log_store.c` (or lower index store path)
-   rather than adding retries in app code.
-4. Restore/commit missing graph index append scripts expected by CTest:
-   - `vendor/amduat-api/scripts/test_graph_index_append.sh`
-   - `vendor/amduat-api/scripts/test_graph_index_append_stress.sh`
+- isolated 3-call index write sequence above
+- `./scripts/smoke_v2.sh` on index backend
+- `./tests/integration_v2.sh` on index backend
