 Purpose: measure basic graph load/adjacency build and shallow path exploration over deterministic fixtures.
 
 ## Fixtures
-- Use interim synthetic fixtures under `samples/graph/interim/graph-50k` or `graph-100k`.
+- Canonical: `samples/graph/graph-40k` (SAMPLES-GRAPH-24-003) with overlay + manifest hashes.
+- Legacy interim (still usable for comparisons): `samples/graph/interim/graph-50k` and `graph-100k`.
 - Each fixture includes `nodes.ndjson`, `edges.ndjson`, and `manifest.json` with hashes/counts.
 - Optional overlay: drop `overlay.ndjson` next to the fixture (or set `overlay.path` in `manifest.json`) to apply extra edges/layers; hashes are captured in results.
 
 ## Usage
 ```bash
 python graph_bench.py \
-  --fixture ../../../samples/graph/interim/graph-50k \
-  --output results/graph-50k.json \
+  --fixture ../../../../samples/graph/graph-40k \
+  --output results/graph-40k.json \
   --samples 100 \
-  --overlay ../../../samples/graph/interim/graph-50k/overlay.ndjson  # optional
+  --overlay ../../../../samples/graph/graph-40k/overlay.ndjson  # optional
 ```

 - Sorted node ids, fixed sample size, stable ordering, no randomness beyond fixture content.
 - No network access; pure local file reads.
 
-Next steps (after overlay schema lands):
-- Extend to load overlay snapshots and measure overlay-join overhead.
+Next steps:
+- Keep results in sync with canonical fixture hashes; if overlay schema changes regenerate fixture + manifests.
 - Add p95/median latency over multiple runs and optional concurrency knobs.

 Purpose: provide a deterministic, headless flow for measuring graph UI interactions over large fixtures (50k/100k nodes).
 
 ## Scope
-- Use synthetic fixtures under `samples/graph/interim/` until canonical SAMPLES-GRAPH-24-003 lands.
+- Default fixture: `samples/graph/graph-40k` (SAMPLES-GRAPH-24-003) with policy overlay hashes.
+- Legacy comparison fixtures remain under `samples/graph/interim/`.
 - Optional overlay layer (`overlay.ndjson`) is loaded when present and toggled during the run to capture render/merge overhead.
 - Drive a deterministic sequence of interactions:
   1) Load graph canvas with specified fixture.
