Retires the shared prefix. Live plans move to the new prefix keeping their
running number; finished and archived files keep the old prefix as
historical record, per the ADR-007 option 2 migration ruling.
Hub UUIDs are unchanged, so reconciliation matches on
state_hub_workstream_id rather than filename and will update the slug in
place instead of registering duplicates.
Assigned in RMGR-WP-0004-T09.

The placement question seeded as open is answered by canon rather than by a
new decision. OAS section 8 defines Q2 Observability as 'telemetry and
monitoring: metrics, logs, traces' - this repo in canon's own words.
The 2026-08-11 coherence review found Railiance had been modelling itself on
one of OAS's six required dimensions and treating everything else as unplaced.
Observability was never homeless; the dimension it belongs to was not in use.
Notes Q7 Governance as the sibling concern - the conformance loop, the other
half of the self-evidencing aspiration this repo serves.
