The docs claimed omp "has no documented vendor-key namespace of its own"
and "the multi-user clamp has nothing to gate" for omp — both false. Per
omp's own docs/environment-variables.md, it reads ~40 provider keys from
env (pi's known 34-key problem in the same shape), and its own knobs are
mostly PI_* (already globally allowlisted): PI_CONFIG_DIR,
PI_CODING_AGENT_DIR, PI_CODING_AGENT_SESSION_DIR, PI_SUBPROCESS_CMD,
PI_SHELL_PREFIX. The first three also move the ~/.omp tree
omp-session-resolver.ts/omp-transcript.ts hardcode, silently degrading
pinning/history — a known gap shared with pi, documented but not fixed
here.
The OMP_* prefix this PR adds brings in OMP_AUTH_BROKER_URL/
OMP_AUTH_BROKER_TOKEN, where omp resolves credentials from — the same
shape DEEPSEEK_BASE_URL is already dropped for in
clampEnvOverridesForOwner(). Add both to OWNER_CLAMPED_ENV_KEYS so a
non-granted owner in multi-user mode can't redirect them, and correct the
false claims in CLAUDE.md, docs/omp-integration.md, and the stale
resolveOmpHome() comment. Also documents omp's default
tools.approvalMode: yolo, which was previously unstated.
