Three review findings on the DeepSeek Harness mode, plus one the third exposed. 1. The multi-user clamp was bypassable by a sibling field on the same request. clampExternalCliBypassForOwner() clamps deepSeekConfig.permissionMode, but DSH_* is an allowlisted envOverrides prefix and applyEnvOverrides() runs AFTER _configureDeepSeek(), so a non-granted owner sending envOverrides.DSH_PERMISSION_MODE landed last and won. Measured on an isolated instance: a session created with permissionMode "read-only" and that override ran with DSH_PERMISSION_MODE=danger-full-access in its pane. Every other CLI's bypass is a command-line flag reachable only through the per-CLI config, which is why the config clamp alone is the whole gate for them. clampEnvOverridesForOwner() adds the env-var half: for a non-granted owner it DROPS DSH_PERMISSION_MODE and DSH_HOME (dropping falls through to what _configureDeepSeek() exports, i.e. the clamped value). DSH_HOME is on that list because it aims the launcher at a profile tree whose plugin code runs at boot, before any approval row can apply. Verified end to end in real multi-user mode: a non-granted user sending both now gets workspace-write and no DSH_HOME, while an unrelated DSH_TELEMETRY_MODE passes through untouched. 2. POST /api/deepseek/install-profile could hang forever. spawn's own `timeout` signals only the direct child, and a plugin install fans out into package-manager children that keep the inherited stdio pipes open, so `close` never fires and the held-open request leaks with no route-level deadline. Reproduced: with a 1.5s built-in timeout the promise was still unsettled after 6s and both fan-out children were alive. Now detached: true plus negative-pid SIGTERM/SIGKILL, the same escalation runGit() uses for the same reason, with a last-resort reap for a grandchild that escaped the group. Same probe after the change: close fires, direct child and both grandchildren dead. 3. hooksAvailableForMode() promised more than a dsh session can deliver. deepSeekConfig.statusReporting: false disarms the HERDR_* export, and that triple is the only reason a dsh session posts hook events, so `until=stop` was accepted and then blocked for the caller's whole timeout: the exact infinite-wait-dressed-as-a-timeout the predicate exists to prevent. It now takes HookCapabilityOptions and every call site passes sessionHookOptions(), with the deepseek arm reading `!== false` so a forgotten one degrades to the old behaviour. The refusal names the setting rather than saying "no Claude Code hooks", which would send the caller hunting a bug that is really a setting they chose. Profile conformance stays unknowable at request time and is documented as such. The stale "True for `claude` and nothing else" docblock is corrected. 4. Exposed by (3): hooksAvailableForMode() was doing double duty as "is this a claude session". Read My Mind (POST /api/sessions/:id/readmymind) and intent capture read Claude's own transcript, and adding deepseek silently widened both to a mode that has none. They compare mode === 'claude' directly now, and a static check pins them there. Verified: full CI gate green (6132 passed), typecheck/lint/format clean, and the wait-signal gating exercised against a live server with a real dsh 0.1.1-rc.2 -- bridge off plus explicit until=stop is a 400 naming the setting, bridge off with no `until` still 200s on idle/exit, bridge on accepts stop.
