# SYNOMAP DIGEST V3 — Bloc G (FS)

[CONTEXT]
Bloc G = intégrité système de fichiers avant ABC.
SRC = authority. DST = strict mirror.

[STATES]
G0: fs_ok
G1: dst_inconsistent
H:  src_missing

[RULES]
- Never touch SRC.
- Never touch /syno/Series or /syno/Films.
- Only purge/rebuild DST.
- One rebuild per run.
- No qB API in G.

[ALGO]
if not exists(SRC):
    state = H   # future jalon
    continue

if not fs_equal(SRC, DST):
    # G1
    purge(DST)
    hardlink_rebuild(SRC → DST)
    if not opportunistic_validate(SRC, DST):
        state = H
        continue

state = G0
pass_to_ABC()

[VALIDATION]
R3 = opportunistic:
- size match → OK
- else → re-evaluate

[OUTPUT]
Digest ready for AI bootstrap.
