Rugby Sentinel follows the signals that determine whether rugby grows, fragments, retreats, or regenerates.

State of the game
Absolute decline, relative decline, and geographic shift are different claims. None are scored here until a source with an explicit unit is connected.

Ecology of rugby
Clubs form. Teams disappear. Players migrate. Strongholds become refugia. New regions emerge. The patterns are visible if we observe them.
Places that still recruit, still field sides, still hold identity.
Clubs isolate. Travel lengthens. Composite names multiply.
New entrants into the stock — not a campaign photograph.
How much rugby the fields, lights and coaches can actually hold.
Players, coaches and legitimacy moving between geographies and codes.
Reserve replenished after a pulse — not the pulse itself.
TTRP
Did the pulse merely occur, or did it replenish the reserve?
1 · Trigger
A global tournament that concentrates attention, broadcast and national identity for a few weeks.
2 · Transfer
Attention, merchandise, casual interest, some trial registrations, political goodwill.
3 · Reserve
Clubs, coaches, fields, junior pathways, volunteers — the things that have to exist after the final.
4 · Pulse
A registration spike, a ratings spike, a spike in conversation.
Did the pulse merely occur, or did it replenish the reserve?
A World Cup that lifts registrations for a season without changing retention, coaching depth or usable field-hours is a pulse without regeneration.

Pathway and code competition
What does a Northern Beaches pathway reveal about where rugby talent goes?

2032 lens
If the Olympics are not the trigger, what is?

Distance, capital, reserve
Can a geographically isolated rugby state replenish reserve, or only receive pulse?

Historic infrastructure case
When is tenure the binding constraint, rather than capital?

Urban carrying capacity
What happens to rugby when land, lights and junior time are all scarce?
