`env -u VAR cmd` and `env FOO=bar cmd` exec a command with a modified environment and print nothing themselves. The old rule matched any `env` token followed anywhere later by a pipe into a filter, so it blocked the documented 1Password write path and forced a `(unset VAR; cmd)` workaround. False positives only — never a leak — but a guard people route around is a guard on its way out. The rule now denies only when everything after `env` is exhausted by options and VAR=value assignments. That is strictly the dumping shape, and it also closes a hole the two previous rules left open: `env FOO=bar` with no command word prints the whole environment and was allowed. Three new deny/allow pairs pin it, including the 1Password write shape that motivated the report. 20 cases now, up from 14, all passing. Closes #25 Bump-Type: patch
