Two classes the traced PMPro survivors named after 1f91c0b:

- The mapper records every named PHP function as an entry of kind
  `function` (3,507 of PMPro's 4,412), and every entry's parameters were
  sources, so internal helpers became injections: sendCancelAdminEmail's
  $user, a gateway hook callback's $user_id/$morder fired by do_action.
  Regions now carry the entry kind; parameters are input only for request
  entries (route, parser, privileged surface). Call depth is unchanged, so
  such a region is still followed into its callees. JavaScript and Python
  emit no `function` entries.
- The object rule is general: a field read continues a flow through the
  bare object only if the taint came through the SAME field, or was
  assigned to the variable or passed in as a parameter. It now also cuts
  $this->Gateway -> this -> $this->user_id (memberorder.php:705).

plausible() memoises the sink test per node and skips the object walk for
paths with no field access (the filter had cost one outlier 101 s -> 160 s).
