Julien Gautier f5e8e6ef61 docs: add ADR-0008 for the identity model (multi-tenant Entra workforce + dual-audience design)
Capture the v1 identity model: Microsoft Entra ID, multi-tenant app with
B2B guest invitation for partner-org employees, workforce-only
authentication in v1. Code and data are architected for dual audience
from day one (Audience enum, audience claim in sessions, audience column
+ RLS policies on shared tables, claims-based authz) so that adding Entra
External ID for customers later is a switch-flip rather than a refactor.

The dev environment uses a Microsoft 365 Developer Program tenant (free,
renewable) to unblock work while the prod tenant is being provisioned by
the org IT contact. Production requires Entra ID P1 licensing - flagged
here so it can be planned, not surprised.

decisions/README.md index updated. CLAUDE.md 'Identity' line now points
to ADR-0008.

Documentation index

This is the entry point to all project documentation. It is maintained automatically: any addition, rename, or removal of a .md file under docs/ must be reflected here in the same change.

Conventions

  • Documentation is written in English.
  • One topic per file. Group related files into a folder when there are three or more.
  • Cross-reference with relative links so they keep working in GitHub, IDEs, and exported sites.
  • For architectural decisions, do not add them here — they belong in ../decisions/ as MADR 4.0.0 ADRs.
