Punch list §25 item 3.7 complete. Added to §25.4 after starting item 4.1 surfaced it as an unbuilt prerequisite -- 3.6's earlier "Phase 3 core complete" claim is corrected in this same commit. StadiumVMQuota table (size STADIUM_MAX_VM_COUNT, linearly searched by vm_id -- capsule_birth.c's vm_id is monotonic and never reused, so it cannot index a table directly, and a 4-entry scan costs nothing). New per-cell stadium_owner byte array records which quota a cell belongs to, needed so eviction returns a freed cell to the correct VM's list and so eviction search stays scoped to the evicting VM's own residents (quota isolation). Free-list linkage reuses each cell's `link` field as a next-free pointer while unresident -- link is documented only as generic "index into the Stadium, not a pointer," so this is a repurposing, not a header change. Does not answer the separate, still-open question of which field carries a multi-cell patron's first continuation-cell index; item 3.5's mass != 1 refusal stands exactly as it was. Boot-time: every cell chained into one list in ascending index order, granted whole to vm_id 0 (Hera), the only VM that exists. Ascending order preserves item 3.6's "Hera is patron zero" invariant once real birth-wiring lands. stadium_admit()'s signature changed to take vm_id -- a change to code shipped in item 3.5, amended there. Pops the calling VM's free-list head first (O(1)); only falls back to a same-VM-scoped eviction search if empty. Caught a real bug before the boot run: the header zero-fill on eviction (and the initial free-list build) both left contains == 0, but 0 is Hera's valid index -- the same collision item 3.1's STADIUM_CONTAINS_NONE fix addressed, recurring at a new site. Fixed by explicitly setting contains = STADIUM_CONTAINS_NONE at both free-list sites. Explicitly out of scope, reported not invented: granting quota to any VM other than Hera is capacity arbitration (item 1.3 left "how much moves per transfer" open). stadium_owner is set once at boot and never rewritten, so quota_slot_for_vm() refuses every vm_id != 0 permanently until item 4.2 adds the grant path and owner-array writes. Verified: three-architecture boot (amd64, aarch64, riscv64), all reaching ok> with identical dict_hash=0x3d4e1daf289da94f matching the item-3.6 baseline.

FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
