6. 2007–present
   Power-sharing has periodically collapsed; sectarian tensions remain. Demilitarisation, however, is described as effectively irreversible and was conducted on a published, monitored basis.

Why it is cited as a reference frame

• Slow but published. The decommissioning and policing-reform timeline was visible to civil society and Parliament throughout.
• Civilian policing was rebuilt, not just renamed. Patten's terms of reference treated police legitimacy in a divided society as the central question.
• Independent monitoring (IICD) was external to both parties.
• Westminster owns this institutional memory directly — Hansard, the NIO, the Patten Report and the IICD reports are all on UK Parliament's own record. This is the comparator FCDO will recognise fastest.

What this is not

• Northern Ireland's history, demography, and external state actors (UK, Ireland, US, EU) differ profoundly from Sri Lanka's.
• The GFA's consociational architecture has produced its own deadlocks; citing the procedural pattern does not endorse Stormont's content.
• Loyalist decommissioning was partial and contested. Citing the curve does not claim it was clean.
• Used here only as a published, monitored, civilian-policing-rebuilt curve — not as a constitutional model.
