lane-w 2170782a81 W: close SvSctOb, DOpts and spies2; named coverage 97.1% -> 98.0%
SvSctOb is a StreamableHelper<SVScriptObject> -- a polymorphic pointer holding a
Game::SVSOSots, which writes two variant lists each dispatched by the key item
before it (xscn -> xsc, EncID -> EncObj). Neither map is on the wire; both were
read out of the game's factories (see the notes repo). The shapes apply the key
in both directions, so a body goes back out as whatever it came in as, and an
unmodelled key still round-trips as a Node. 18 new shapes: SVSOSots, the four
scenario bodies (traps / crowdefs / indsys / gmtrigger -- indsys really does
serialize nothing, its Read and Write are both the shared `ret 4` stub) and the
eight encounter bodies the saves exercise. The four factory ids no save carries
(7 SystemKiller, 8 PuppetMaster, 14 Locust, 21 Ortgay) are deliberately NOT
typed: their serializers are recovered but nothing could check a shape for them.

DOpts and SVSOVonNeumann::trev are VectorHelper<Mars::String>, so read_elem /
write_elem / SchemaBuilder::carr grew the std::string branch lane G listed as
missing. spies2 is VectorHelper<int>: the TYPE is certain from the helper's own
decorated name, but the count is 0 in all 28 systems of all four saves, so no
element value has ever been observed -- the shape is a hypothesis about
behaviour even though it is a fact about type. Same for SysMem and mts.

Conformance 56 shapes / 657 items -> 74 / 769, still 0 MISMATCH, and every new
binding is 0 wire-only and 0 shape-only. Coverage 97.1/97.2/97.2/97.6 ->
98.0/98.0/98.0/98.4 with the byte-identical round trip preserved; ratchet
95.0 -> 97.5. CD is now the only remaining region of size, and it stays opaque:
the recovered 44-item Game::TurnCommands sequence cannot be aligned to the
save's 35 items even as a subsequence (item 4 is 8 bytes, so a bool where the
recovery says i32; and the 27 trailing ints have only 22 i32 slots to come
from), which proves the no-orders diagnosis rather than assuming it.

Two unit tests added that need no saves: the string-array element branch
(including the empty string, which is four zero bytes and so looks like int 0)
and the SvSctOb variant dispatch round trip.

ctest 34/34, clean_room_check OK, test_save skips cleanly with SOTS_SAVES_DIR
unset. sots_stream_schema.h unchanged: streams.py and gen_stream_schema.py were
re-run and the output is byte-identical apart from the provenance line.
