references/crt-startup-and-main.md covers what runs before main: the entry
symbols the linker places, the startup order under VS2015 and later, the VC++ 6.0
prologue, __chkesp and SEH tells in 32-bit builds, the /GS cookie construction,
and the procedure for reaching main in a stripped image.
assembly-idioms.md gains two sections: structure layout and stride (pack
arithmetic, by-value copies, hidden return pointers, two-dimensional strides)
and dispatch shapes (comparison chain, address table, offset table, binary
tree), with the case set recovered from the bounds check rather than from
quoted thresholds.
Register the file in both symptom tables, the routing index, the coverage and
route-inventory tables and the evidence note. The startup shapes come from a
public tutorial corpus and are graded unverified; only the call into main,
observed in a run, would promote them.
