From 2170782a817e58f234b59ba8a38d588751992c41 Mon Sep 17 00:00:00 2001 From: lane-w Date: Tue, 8 Sep 2026 07:04:45 -0400 Subject: [PATCH] W: close SvSctOb, DOpts and spies2; named coverage 97.1% -> 98.0% SvSctOb is a StreamableHelper -- 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, so read_elem / write_elem / SchemaBuilder::carr grew the std::string branch lane G listed as missing. spies2 is VectorHelper: 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. --- docs/G-wire-schema.md | 20 ++ src/mars/stream/archive.h | 5 +- src/mars/stream/shapes.h | 435 ++++++++++++++++++++++++- tests/mars_stream/test_save.cpp | 2 +- tests/mars_stream/test_stream.cpp | 117 +++++++ tests/mars_stream/test_wire_schema.cpp | 23 ++ 6 files changed, 592 insertions(+), 10 deletions(-) diff --git a/docs/G-wire-schema.md b/docs/G-wire-schema.md index 968aa09..1cbeda5 100644 --- a/docs/G-wire-schema.md +++ b/docs/G-wire-schema.md @@ -76,3 +76,23 @@ cannot supply — and the table is what proves they agree with the binary. 3.
