Phase 2, task 2.1 only: type definitions, wired to nothing, drawing no
heat -- no allocator, no protocol logic, no registration anywhere.
FABRIC-3.5.md SXXII.4: Phase 2 structures come first and prove nothing
until the allocator is built on top (task 2.2 onward, each its own
commit).
Added include/starkernel/vm/kernel_hermes.h:
SkHermesMessage -- field-for-field mirror of messaging.4th's live
9-cell MSG-* layout (type/from/to/payload addr+len/Stadium cell
index/seq/channel/orig-type), per SXXXIII.4 item 1 ("roughly half the
file is accessors that become struct fields"), plus an explicit
in_use flag for task 2.2's allocator. Deliberately no separate heat
field: per SXL.4, a message's heat IS the Stadium cell it occupies,
not a value copied alongside it -- one source of truth for the
conservation invariant stadium_conserved() (task 0.7) checks.
SkHermesMembership -- one flat broadcast membership list, SXXXIII.4/
SXXXIII.5's recommended replacement for messaging.4th's 28-word channel
abstraction (traced to exactly one live caller, CH-ADD-MBR). Item 27
(negotiation vs. broadcast, Phase 3 blocker B1) is not answered by this
structure and isn't meant to be -- a flat list is correct either way.
Genuinely wired to nothing: no .c file, no Makefile change, no include
from any compiled source. Syntax-checked standalone (gcc -std=c99
-Wall -Wextra -Werror -fsyntax-only) before touching the real build.
Boot byte-identical to task 1.9's baseline on amd64 (same dict_hash
triple, zero UNKNOWN WORD). Did not repeat aarch64/riscv64 -- the file
compiles into no object on any architecture, so there is no mechanism
by which it could diverge.
Authorized by Captain Bob ("yes").
