pastilhasandClaude Opus 5 6a85ca5d1f the binary check that was a comment, and a guard that could fire
Four fixes from the live server's review. One was a real defect.

THE BINARY WAS NEVER CHECKED. spawn-as-member passed `command` from the SDK
through untouched while a comment claimed the member's own install was what ran.
Since claude-manager resolves the OWNER'S CLAUDE_BIN at module load, wiring the
hook would have exec'd the owner's binary as the member — the precise confusion
this file exists to prevent, asserted in prose and enforced nowhere. Now throws
unless the command resolves to claudeBinIn(run.home).

NEVER_ENV COULD NOT FIRE. It tested an environment that memberEnv builds from
ALLOWED_ENV, so a denied name was already impossible; it was also missing six
credential variables the installed SDK reads. Replaced with the subset check the
reviewer proposed: anything not in ALLOWED_ENV or {HOME, CLAUDE_CONFIG_DIR} is a
leak whatever it is called. Complete by construction, and it cannot rot as the
SDK grows variables — which the denylist provably had already.

Also: one derivation of the binary path instead of two (install resolved from
the email, exec from the home — fine until they disagree), and the constraint
that ALLOWED_ENV may never hold a secret written at the list itself, since
`env K=V` in the argv is visible in /proc/<pid>/cmdline to every account.

Not acted on, and said so in COMMS: their finding that the 711 in 401dcb7 is
inert, and that a retrofit needs a mode pass. Both are theirs. Nor pulled chat
from DEFAULT_ROLE_CAPABILITIES despite agreeing a member currently sees a tile
that 403s — that is the owner's call, not a defect.
