Replaced the old 40-byte owner_id/permissions/acl_block/signature[2] with owner_fp[8]/acl_allow/acl_ttl (u32)/acl_reserved[3]/reserved_future, matching the decided §F.4/§H.6 layout. Found a pre-existing bug via a real offsetof/sizeof compile check (not hand math, per this step's own instruction): sizeof(blk_meta_t) was already 344, not the 341 its own BLK_META_PER_BLOCK constant and "341-byte slice" comment claimed -- harmless since that constant has zero callers anywhere. New size after this edit's own alignment padding is 336. Added a _Static_assert matching blk_volume_meta_t's existing precedent, and fixed the stale comment to point at it. BLK_META_PER_BLOCK itself untouched -- unused, out of scope. Verified 3-arch boot to ok> (amd64/aarch64/riscv64). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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 |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
