host found a live credential exposure while answering my question about what
else the member branch missed. It was outside the diff, and predates all of it.
MCP-CONFIG WAS NOT BRANCHED. mcpHostPath is module-level, written once at the
owner's bootstrap, and was applied to every turn. Its env block carries
OFFICER_AUTH_TOKEN, a 30-day JWT signing as the owner — so a member's turn would
have spawned their MCP server holding it. Now inside the params.member ternary
alongside the binary and the spawn, for the reason already written there: these
values say whose turn this is and have to move together. A member gets none.
What they should get instead is undecided, and undefined beats the owner's.
THE FILE WAS 0644. Written with a bare writeFileSync into a 755 directory, on a
host where `terminal` is granted to every role by default — so any member could
cat it and hold owner-level API access on loopback. host verified that as a real
member on the production host rather than reasoning about it. Now 0600.
The mode is the only half of that which is code. The token has been
world-readable and stays compromised until rotated, the directory chain above it
is still 755, and neither is fixable from a commit. Both written up for the
owner in COMMS 05, along with why I am stopping here rather than continuing:
the next commit should be the rotation, not more feature work stacked on top of
an open exposure.
