Robert Allan JamesandClaude Sonnet 5 b031b802e3 Rename FABRIC series: FABRIC.md->0, FABRIC-2.md->1, FABRIC-3.md->2, FABRIC-4.md unchanged
FABRIC.md -> FABRIC-0.md
FABRIC-2.md -> FABRIC-1.md
FABRIC-3.md -> FABRIC-2.md (the current/living document)
FABRIC-4.md unchanged (new #3 to follow separately)

Every cross-reference repo-wide updated to match, including doc-comment
citations inside kernel source (.c/.h) files -- done via an ordered
placeholder substitution (FABRIC-3.md->placeholder2, FABRIC-2.md->
placeholder1, FABRIC.md->placeholder0, then placeholders resolved to
final names) in a single pass per file to avoid double-shifting
already-renamed references.

One line in capsules/font.4th grew past the 64-char block-format limit
as a side effect of the longer filename; shortened it and reverified
with mkcapsule --lint (34/34 pass) before rebuilding.

Verified 3-arch boot to ok> (amd64/aarch64/riscv64, each in the
foreground) after the fix; logs and DoE CSVs from this session's
verification runs included per this repo's own audit-artifact
convention.

Robert Allan JamesandClaude Opus 5 a621131ef6 §H.12 step 3: session_set_pinned/session_is_pinned pin-authority choke point
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.

Robert Allan JamesandClaude Opus 5 6d9fe3f515 §H.12 step 2: session-slot table, session_find/session_register
src/starkernel/vm/session.c: kmalloc'd-at-boot slot table sized from
stadium_max_vm_count() (mirrors stadium.c's own StadiumVMQuota, not a
fixed compile-time array as originally planned -- that table was already
moved off a fixed array for the same "population isn't knowable in
advance" reason). session_boot_init()/session_find()/session_register()
implemented for real, no stubs; session_register() zeroes identity and
leaves pinned=0, matching VMIdentity's own documented default and
deferring pin policy to callers. Added session.c to Makefile.starkernel's
explicit source lists. No callers yet.

Robert Allan JamesandClaude Opus 5 668e36bb17 §H.12 step 1: add Session struct (type only)
include/starkernel/session.h: vm_id (VMUuid), pinned (int, authoritative
over Stadium's STADIUM_FLAG_PIN per H.10), parent (VMUuid), name (fixed
64-byte buffer), identity (embedded VMIdentity, reusing the existing
type rather than inventing a new one). No logic yet, no callers -- next
step wires the session-slot array and register/find functions.
