Rosters and qualification tracking that know who can actually go.
Sinkaos keeps people, qualifications and kit in one place, suggests a roster with its reasons, and leaves the approval to a person. This is the RESOURCE stage of the Sinkaos loop: it reads who and what you have from your world model, and once the roster is approved each phone downloads its own mission pack.

The spreadsheet says she is qualified. The certificate ran out in March.
Training records sit in one spreadsheet, the rota in another and the kit list on a clipboard in the store. Whoever builds the roster carries the rest in their head: who holds the boat ticket, who has done three weekends running, which vehicle is off the road. When someone drops out on Friday night, the answer is a phone round.
The dates behind this are real obligations. HSE says first aid at work certificates last three years, and first-aiders need to requalify before they expire. Equipment used to lift people must be thoroughly examined every six months, or as a written examination scheme sets out. Each date is simple on its own. A team with dozens of them, per person and per item, needs to see what they mean for Saturday.
A two-day event, from the compliance matrix to every phone.

MonThe plan says what it needsThe plan for a riverside festival calls for six first aiders, two boat crew, four drivers and a duty lead on each day. A feasibility check compares that with the people, qualifications, vehicles and equipment available.FeasibilityPlans

TueThe matrix shows the gapThe compliance matrix shows who is current, due, overdue or missing a qualification. One first aider is overdue and two boat crew are due this month. The overdue one enrols on Thursday’s course.Compliance matrixEnrolment

Qualification tracking, rosters and equipment readiness together.
Compliance matrix
Who is current, due, overdue or missing a required qualification.
Qualifications with evidence
Training, badges, roles, languages and driving licences in one model, with expiry and rules such as “renew first aid every 12 months”.
Expiry alerts
Reminders before things expire, and staffing alerts for gaps and shortages.
Suggested rosters
Availability, existing commitments and travel time count. A person approves the result.
Workforce system connections
Connect the volunteer and staff management system you already use, and import shifts and positions from it.
Kit readiness
Usable, incomplete, broken or in repair, with maintenance and inspections that change the status.
Loadouts
What an operation or exercise needs, what was issued and what came back.
Vehicles
Inspections, defects and repairs, so a plan does not assume a vehicle that is off the road.
What the person building the roster can check, and where.

| Who has done too many weekends? | Someone remembers | Fairness is part of the ranking |
| Who said yes? | Scroll through the group chat | Accepted, declined or cancelled, with history |
| Is the boat ready? | The clipboard in the store | Condition, inspections and repairs |
| Is the kit where it should be? | Go and look | Expected and actual location, kept separately |
