Part 2 of 4 for issue #40. Depends on PR 1/4 (#47, now merged). Adds the France corridor: 2 French sources, 2 French institutions, and the LU–FR corridor scenario.


Context

France is the largest frontalier corridor for Luxembourg — approximately 120,000 workers cross the border daily. This PR encodes the sources and institutions a Luxembourg-connected family with French ties would interact with, and wires them into a corridor scenario that references the cross-border conditions and EU regulations from PR 1.

URL verified: https://www.carsat-alsacemoselle.fr — loads correctly.

  • id: institution:fr:carsat-alsace-moselle — deliberately the Alsace-Moselle CARSAT, not a generic CARSAT record, because this CARSAT directly borders Luxembourg and specifically handles Luxembourg frontalier pension coordination

  • Organises personalised advisory sessions with Luxembourg CNAP representatives

  • verification_status: discovered — the specific SCEC transcription page content was not fully verified; honest status applied

Hi Hiren!

Thank you so much for another excellent and high-quality contribution to Clarvia! ❤️

The data structure for the Luxembourg-France corridor looks incredibly clean and complies perfectly with our schemas. The inclusion of the mixed career form (formulaire carrière mixte) details in the CARSAT notes is a fantastic, highly relevant detail for cross-border frontaliers.

Everything looks good and the validation checks passed. I'll merge this PR now using squash-merge.

Thank you again for driving the cross-border corridor implementation forward so rapidly! We really appreciate your help.

access

## Verification status honesty

Belgium sources are `source-checked` — URLs verified loading, content
confirmed.
Portugal sources are `discovered` — URL identified from official portal
structure but could not be verified loading during creation. This is
consistent with issue #40's own note: "Detailed survivor-pension routing
and death transcription process need further verification."

---
