session_is_pinned() reads Session.pinned directly (authoritative, no Stadium re-derivation); session_set_pinned() writes both Session.pinned and the mirrored STADIUM_FLAG_PIN bit on the session's own patron cell, keeping Stadium's internal eviction/admission logic (which must stay self-contained) in sync without it calling back into session.c. Added Session.stadium_cell (index into stadium_cells()) -- necessary plumbing not in the original H.2 field list; the choke point can't reach the right patron header without it. Moved STADIUM_FLAG_PIN from a stadium.c-private #define to stadium.h (public) so session.c can reference it without a duplicate definition. Verified 3-arch boot to ok> (amd64/aarch64/riscv64).

capsules/
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.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
