+  NEO-70 craft HTTP. CraftResponse emits explicit null for reasonCode / xpGrantSummary when absent (mirror inventory POST). Run order within folder: deny requests (seq 1–4) then spine (seq 5). Full collection runs after dotnet test on shared Postgres — insufficient-materials clears refined stock; spine reuses persisted scrap and tolerates node_depleted gathers. Deny setup requests may use inventory POST only where noted.
