impl/js/src/email.mjs (written from CONTRACT.md + FLOWS.md): both roles,
case store, handoffs, timeouts, one-cap outbox with holding, authorization.
Passes all 22 flows from the bundle; with the JS master all 12 slave
flows (no Python contract party). Writing it found six contract gaps,
folded into the draft as MCP-1..6 (acknowledgement, details convention,
resume names the outcome, opaque case key, error table, transfer
reporting); flows now check outcome tokens, not reference prose. A
mutation check found a missing flow: a-008 (per-type master check).

impl/js (Node, zero deps, written from the specs): parser, v0.2
statute-aware rules, signing, outside master. Passes addresses.json,
statute-aware.json and auth.json unchanged; its master passes the 11
slave-setup mode flows against the Python email side (ExternalMaster).
Differential testing vs mas_core found two unstated stand-in rules, now
SCP-9 in the v0.2 draft with fixtures si-011..013, dt-109; ABNF comments
no longer say v0.1. Runner: external masters, step errors fail the flow.
