## Summary ADR-0025 was merged as `proposed` in #201. The test tenant (`apfrd.onmicrosoft.com`) has since been provisioned with the full role / user matrix — 4 privileges + 24 security groups + 19 users with all assignments per the persona table. The ADR is now the implementation reference, so this PR: 1. Promotes the ADR from `proposed` to `accepted`. 2. Syncs the document with what is actually in place — the privilege catalogue grows from 1 to 4 entries (the previously "anticipated future" privileges that the test tenant already has), and the persona matrix grows from 10 to 19 entries (so every one of the 24 functional-role groups has at least one member, closing the gap that prompted `notes/test-tenant-role-assignments.md` and `notes/entra-group-members.md`). 3. Records the Entra app-role GUIDs in a new "Provisioned in the test tenant" subsection for traceability — the GUIDs are stable IDs the implementation will need. 4. Updates the index + the `CLAUDE.md` roll-up. No code changes. No implementation skeleton — that lands in the next PR (proposed: `feat(libs/feature/auth): authorization types + Principal builder skeleton`). ## What lands | File | Change | |---|---| | `docs/decisions/0025-authorization-model-privileges-roles-scopes.md` | Frontmatter `status: proposed → accepted`; privilege catalogue extended from 1 to 4 entries; persona matrix rewritten from 10 to 19 entries; new `Provisioned in the test tenant (2026-05-20)` subsection capturing the four app-role GUIDs. | | `docs/decisions/README.md` | 0025 row: `proposed → accepted`. | | `CLAUDE.md` | Roll-up `0001 → 0024 accepted` → `0001 → 0025 accepted`; Architecture list grows an "Authorization model" bullet. | The two operator-facing notes files (`notes/test-tenant-role-assignments.md`, `notes/entra-group-members.md`) are gitignored and unchanged — they served their purpose during tenant provisioning and remain as runbooks. ## Notes for the reviewer - **Why promote now rather than couple with the first implementation PR (the pattern from #194 → #195 → #196).** The Entra-side provisioning *is* the implementation for this ADR — the next PR is a portal-side reflection of decisions that are already concrete in the tenant. Promoting now keeps the document honest about what the test tenant runs against. - **Why all 4 privileges enter the v1 catalogue.** The ADR originally shipped `Portal.Admin` as the sole v1 entry and listed the other three under "anticipated near-future entries". The test tenant has all four; the catalogue should match. The three new entries are explicitly marked "provisioned; consumer surface deferred" so a reader does not look for non-existent surfaces. - **Why 19 personas, not the cleaner 24 (one per role).** Several APF jobs genuinely combine multiple roles (RH siège often handles paie + compta; DPO often wears the quality officer hat; local delegates often grow out of volunteer roles). Densifying these existing personas is more faithful to real APF org structure than inventing 14 single-role test users. Distinct personas were created where the *scenario* is distinct (scope variations, governance positions) — see the matrix in the ADR for the breakdown. - **Why `apf-role-partenaire` stays empty in v1.** Placeholder per the original ADR; no consuming surface to test against. The group exists in Entra so the schema is locked, but a user assignment without a guard to exercise would be theatre. The first partner-facing feature adds the user. - **GUIDs in the ADR.** The four app-role GUIDs are repo-stable identifiers; recording them in the ADR keeps the document self-sufficient when a future contributor opens it without access to the Entra portal. The 24 functional-role group GUIDs are tenant-specific and stay in a gitignored `infra/test-tenant.entra.json` once the implementation PR creates it — referenced by name only in `libs/feature/auth/src/lib/entra-group-to-role.ts`. - **No `prettier --write` damage.** The persona matrix is a wide table; Prettier sometimes reflows wide markdown tables. The diff is clean — Prettier left the table intact on this run. ## Test plan - [x] `prettier --check docs/decisions/0025-authorization-model-privileges-roles-scopes.md` — passes (hook ran on commit). - [x] Markdown links inside the ADR still resolve (`0020`, references to other ADRs unchanged). - [x] Status row in `docs/decisions/README.md` reflects `accepted`. - [x] `CLAUDE.md` roll-up line + Architecture list updated; no other instances of "0024" needed bumping. - [ ] **Review focus** — the expanded privilege catalogue (4 entries, one of them already had a guard, three new ones documented), the 19-entry persona matrix, the "Provisioned in the test tenant" subsection (especially the GUIDs — make sure none was mistyped from `notes/role-user.txt`). ## What's next With ADR-0025 accepted, the implementation phasing recorded in its `§More Information` opens: 1. **PR — `libs/feature/auth` extension** : `authorization.types.ts` (catalogue constants for the 4 privileges + 24 functional roles + 6 scope kinds), `entra-group-to-role.ts` (slug map skeleton with placeholder GUIDs ; the operator drops real GUIDs into `infra/test-tenant.entra.json` separately), `Principal` builder hook on the OIDC callback, no new guards yet. 2. **PR — `@RequireRole` + `@RequireScope` decorators + guard tests** : real composition tests against the 19 personas. 3. **PR — drift CI gate** : ESLint custom rule asserting every `@RequireRole('...')` literal in code is in the catalogue. 4. **PR — `prisma/seed.ts` for `user_scopes`** : depends on the `Person` + `User` schema (proposed ADR-0026). --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #205

Architectural Decision Records
This project records architecturally-significant decisions as ADRs in the MADR 4.0.0 format. References: adr.github.io.
Why ADRs
ADRs capture the why behind a decision — context, drivers, options considered, trade-offs accepted — at the moment the decision is made. They make architecture reviewable, onboarding faster, and prevent the same debate from being re-litigated later.
Conventions
- Format: MADR 4.0.0. Start from template.md.
- Filename:
NNNN-kebab-case-title.md, e.g.0007-adopt-tailwind-for-design-tokens.md. - Numbering: globally sequential 4-digit prefix. Numbers never reset, never get reused — even when an ADR is superseded or deprecated.
- Layout: flat folder. ADRs are not nested into category subfolders; topical organization happens via tags.
- Tags: every ADR carries a
tags:array in the MADR frontmatter, drawn from the tag vocabulary below. An ADR may carry several tags. Propose new tags (or renames) in the same PR that needs them; never invent ad-hoc tags inline. - Status lifecycle:
proposed→accepted→ optionallydeprecatedorsuperseded by [ADR-NNNN](NNNN-other.md). Update the YAML frontmatter; never delete an ADR. - Index maintenance: every ADR addition or status change must update the Index below in the same commit.
When to write an ADR
Write one whenever a development decision is non-trivial: tool or library choice, framework pattern, security control, perf budget, a11y target, naming convention, deprecation, breaking change, or any choice that future contributors would benefit from understanding the why of.
Tag vocabulary
The vocabulary below is the source of truth. It is intentionally coarse — propose extensions only when an existing tag genuinely doesn't fit, and avoid overly narrow tags.
| Tag | Scope |
|---|---|
frontend |
UI, Angular, components, design system, client-side state |
backend |
API, BFF, server-side services |
security |
AuthN, AuthZ, sessions, CSP, dependency scanning, secret management |
performance |
Perf budgets, caching, bundle size, Lighthouse |
accessibility |
WCAG, a11y testing, keyboard, ARIA, contrast |
infrastructure |
CI/CD, hosting, deployment, runtime |
observability |
Logs, metrics, traces, correlation IDs, monitoring |
data |
Persistence, schemas, migrations, data flow |
process |
Team conventions, workflows, repo policy |
Status: starter vocabulary, to be refined as ADRs accumulate. Update this table whenever a tag is added, renamed, or retired.
Index
ADRs are listed in numerical order. To slice by topic, filter on the Tags column.
