Installing the fixed compiler exposed a blind spot in this gate. On clean main,
with no source changed, soulc-stamp reported OK while the committed amalgam had
gone stale by a line — because the fingerprint covered .el sources and not the
toolchain that turns them into dist/soul.c. That is exactly the class of silent
divergence the gate was written to close, and it had it.
The stamp now fingerprints the elc binary alongside the sources. Demonstrated: with
the old stamp the gate passed after a compiler swap; with this change the same
condition fails, naming __compiler__.
dist/soul.c regenerated under the installed compiler (1,205,027 bytes) and verified:
builds from its own committed input, the declared principal is present in the
resulting binary, interface 110 routes in / 110 out.
Differential evidence that the new compiler is a strict superset — same sources,
both compilers:
neuron soul 1 differing line, the el_cgi_init emission
engram server.el 0 differing lines
mcp-wrapper 0 differing lines
mcp-proxy 0 differing lines
