Ships the runnable acceptance test ADR-156 spec'd. Drives a single
LocalBackend through the full substrate contract in one test:
1. Recall: search_one → results
2. Verify: publish_bundle → read_from_dir → verify_witness
→ cache pointer matches on-disk witness
3. Forget: invalidate_cache → pointer is None
4. Rehydrate: next search_one → primes+1, pointer reinstalled
5. Location- results before forget ≡ results after rehydrate
transparency (byte-exact ids + scores at the same seed); the
caller never touched data_ref or knew which tier
served the call
6. Compact: explicitly out of scope per ADR-156 — belongs to
RVM/Cognitum, not the substrate
If this test stays green on every commit, the agent-facing memory
substrate claim is mechanical, not aspirational.
Also closes ADR-156 open question #4 (substrate test needed) as
resolved.
21 federation + 9 bundle + 3 fs_backend = 33 tests passing. Clippy
-D warnings clean.

Memory audit finding #4: encode_query_packed previously did q.to_vec() // alloc #1 (unit buffer) self.rotation.apply(&unit) // alloc #2 (rotated buffer) vec![0u64; n_words] // alloc #3 (returned packed words) per query. 3 heap allocations per search, firing at ~10k QPS, caused measurable allocator contention under concurrent load. Fix: thread_local scratch holds (unit_buf, rotated_buf) across queries on the same thread. RandomRotation gains an apply_into(&[f32], &mut [f32]) variant that writes into the scratch rather than allocating. Only the returned Vec<u64> is freshly allocated (the caller needs ownership). Net: 3 → 1 allocation per query on the hot path. New RandomRotation::apply_into is the building block for future in-place paths; apply() is now a thin wrapper around it. Measured QPS lift at n=100k (stacked with earlier iter-2/3 security + flatten): single-thread QPS: 2,975 → 3,137 (+5%) concurrent 1-shard: 23,681 → 24,255 (+2%) The uplift is smaller than the profiler's 30–50% estimate because at n=100k the scan dominates query encoding. On smaller collections (n=5k) where encoding is a larger fraction the relative win is similar. Allocator contention dominates only at much higher QPS. 23 rabitq tests passing. Clippy -D warnings clean. Co-Authored-By: claude-flow <ruv@ruv.net>
