By August 19, 2026, HM Government will not have issued a statutory instrument, machinery-of-government change order, or written ministerial statement formally designating at least one named administrative function as transferred from a Whitehall department to Greater Manchester Combined Authority operationalizing Burnham's declared shift; the initiative will remain at the stage of political declaration, working group formation, or framework consultation document.

The Institutionalist framework provides the highest-specificity mechanistic analysis: UK affirmative SI procedure alone requires 6-8 weeks minimum, the approximately ten-week window to August 19 is technically insufficient absent a pre-drafted instrument, and no commitment device bridges the announcement-to-order gap. The Austrian rent-seeking model independently confirms stall through a different mechanism: each Whitehall department faces asymmetric costs from voluntary jurisdiction surrender (concentrated, immediate) against diffuse, delayed benefits for Manchester recipients, and the political market for devolution is satisfied by announcement before operationalization costs are incurred — removing the incentive structure. The Keynesian coordination failure model adds that institutional liquidity preference under the Starmer government’s currently depressed-confidence environment further suppresses inter-departmental risk-taking; the paradox-of-thrift analog predicts each department waits for Treasury to move first, and Treasury holds highest institutional liquidity preference of all. The Marxist outlier contributes the one mechanism that could falsify: legitimation pressure on a Labour government facing Northern delivery expectations is real, and a coordination-transfer substitution (NHS boundary alignment, skills partnership restructuring) could be announced as concrete devolution without altering the fiscal extraction architecture. The base rate from UK devolution history is approximately 20% probability of formal transfer within two months of announcement; framework analysis leaves this largely intact, adjusting upward slightly for GMCA pre-existing infrastructure (+5%) and Marxist legitimation pressure (+5%), yielding approximately 30% probability of formal transfer and 70% probability of stall by August 19.
