   Thanks @DanielLeens @SEZ9 — fully aligned on both notes.
   
   I will keep the 4 GiB JMH fork budget and the earlier full-WAL reload OOM 
(`34317023975` on `432bdb3d9`) as supporting acceptance context only. I will 
**not** treat the local `-Xmx2g` single-key smoke (`5bbc304b2`), or a heap 
budget alone, as proof of selective loading / no-retention.
   
   The functional gate stays as you both stated:
   
   1. **Phase A** (first, after #12173 is healthy and merged): prove the keyed 
file-storage contract with deterministic `FileMapStore` / WAL-reader tests 
(filler keys, overwrite/tombstone cases, no unrelated keys, no whole-map 
retention), plus a constrained-heap diagnostic on the same 
`initialStoredJobCount=1000` shape as like-for-like supporting evidence. The 
SPI default full-load-and-filter path will not be what Phase B relies on.
   2. **Phase B** (only after Phase A is merged and shown selective): widen the 
durability sample to the full batch **outside** the measured `SingleShot` path, 
with an explicit tear-down-only assertion in the initial revision. Phase B will 
reference the merged Phase A change.
   
   On the parent PR: #12173 head remains at `7948e2640` (no further pushes 
unless a re-review asks for changes). Code review items F1–F6 are closed there; 
the remaining gate is the stale `CHANGES_REQUESTED` docs review (already 
addressed in `9a6077c58`) plus clearing the blocked merge state. I will **not** 
start a storage or benchmark implementation PR for this issue, and will not 
stack work on that branch, until #12173 is healthy and merged.
   
   No label/assignee changes from my side. Thanks again for the clear gate.
