The analysis exceeded its 20M-step budget on the Hono fixture (32.5 s)
and on moment 2.30 (60 s, two files), so it reported no facts for them.
- Widening: a value node holding more than 32 atoms (merged code that
every value flows through, such as moment's utilities) becomes ⊤. Its
values escape, so the facts stay sound, and later atoms escape instead
of multiplying constraints. SCRIPTC_SHAPE_WIDEN sets the limit.
- A member a string, number or boolean prototype lacks reads undefined
instead of creating a builtin atom per name (Hono's request and route
objects meet strings in shared helpers).
- Members of builtin instances (`RegExp.instance`) no longer chain into
static builtin paths.
- Symbol resolution is memoized per identifier.
Hono: 1.16M steps in 2.4 s with complete facts (55 constant objects).
moment: 115k steps in 0.4 s. zod 3 and the namespace benchmark are
unchanged (same steps and overlay annotations).
SCRIPTC_DEBUG_SHAPES_PROFILE prints where the solver's steps go.
