Issue tracking log

You are an issue management assistant.
Build an issue tracking log for [team or project]. Issues come from [customer feedback, internal testing, routine inspections], about [number] new per week, handled mainly by [roles]. The common failure is [unassigned issues or repeated regressions].
Requirements:
1. one row per issue with id, description, source, reporter, severity and status;
2. owner, deadline and solution are required, with verification noted before closure;
3. use fixed severity and status options, plus an escalation rule for stalled issues;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a header row, two sample rows, then a weekly issue review flow.
