Subject: [PATCH] =?UTF-8?q?feat(service):=20P4=20doc-faithfulness=20?=
 =?UTF-8?q?=E2=80=94=20SLA=20placeholder=20columns,=20issueSubclass,=20tra?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds ticket.slaDueAt + ticket.issueSubclass + queue.slaPolicyRef (placeholder
columns, no timer logic until P7) and propagates ticket.traceId onto
ticket.state.changed events (assignment + transition). 45 tests still green.
