The body-local #run fold in emitCall was effectively dead (gated on args.len==0, but the __ct comptime wrapper always carries the implicit *Context arg), so every body-local #run fell through to a RUNTIME call: bridgeable shapes lucked into the right value; an unbridgeable shape (e.g. [2][]i64) ran over --- storage -> garbage, exit 0, no diagnostic. Fold any is_comptime callee (gated !enclosing.is_comptime so nested metatype calls in a comptime wrapper's dead body aren't folded). On a tryEval bail, distinguish a BRIDGE bail (result can't regToValue- materialize -> error: comptime init of 'X' failed: <reason> + comptime_failed, build fails, symmetric with the global #run path) from an EXECUTION bail (VM can't run the body, e.g. NaN/extern -> runtime fallthrough, preserving types/0150), via comptime_vm.last_bail_was_bridge (reset at tryEval entry, set only at regToValue). The const name is threaded onto the wrapper (comptime_display_name) so the diagnostic reads the source name, not __ct_N. Regressions: diagnostics/1204 (negative), comptime/0645 (positive). Verified by 3 adversarial reviews, suite 801/0.

// A body-local `#run` const of a BRIDGEABLE shape — a scalar, a struct, an
|
|
// array, or an `?Array` optional — evaluates and produces its const value.
|
|
// These are the common cases that must keep working alongside the issue-0182
|
|
// fix (which fails ONLY the unbridgeable-result case, e.g. `[2][]i64`).
|
|
//
|
|
// Regression (issue 0182): the body-local `#run` fold must not regress the
|
|
// bridgeable cases when it learned to fail loudly on an unbridgeable result.
