Observer flag on switch-signal slots, set by the kernel for the Tripod (is_fleet_foundation, hoisted; Hera in kernel_main). The decision: an observer in progress or holding an event keeps the CPU; observers with events (mail, Hera's console input) go ahead of participants, oldest wait stamp first; participants compared by work heat as before. Observers are never charged (O-2) nor floored. Uncommitted heat-share charge discarded. Evidence, byte-identical amd64/aarch64/riscv64: G interleave unchanged; Hestia's mail runs before any worker output (HHHABB...); a line typed while two workers run is read and executed mid-stream (...ABAB1 2 + . / 3 ok / ABAB...) -- console responsive under load. Relay 3, dict_hash unchanged. Busy-wait DOE deliberately not run (deadlocks by design until O-C). FABRIC-3.9.0 records rulings and Captain Bob's messaging note (§7).

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.
