## Summary Promotes [ADR-0026](docs/decisions/0026-person-user-portal-data-model.md) and [ADR-0027](docs/decisions/0027-portal-side-organisational-hierarchy.md) from `proposed` to `accepted`. Both shipped as `proposed` in #217 after the cascade / acteurs_plus source-of-truth audit reshaped the org-hierarchy model. No open questions left on either. No code changes — same shape as #205 (ADR-0025 acceptance). ## What lands | File | Change | | --- | --- | | `docs/decisions/0026-person-user-portal-data-model.md` | Frontmatter `status: proposed → accepted`. | | `docs/decisions/0027-portal-side-organisational-hierarchy.md` | Frontmatter `status: proposed → accepted`. | | `docs/decisions/README.md` | Rows for 0026 and 0027 flip to `accepted`. | | `CLAUDE.md` | Roll-up bumped to `0001 → 0027 accepted`; two new Architecture bullets ("Portal-side identity model" and "Portal-side organisational hierarchy") added after the ADR-0025 bullet; ADR-0025's bullet adjusted to clarify the scope literal `etablissement:<structure-code>` (with a pointer to ADR-0027 for the `Structure.code` semantics); the `@RequireScope` Prisma-resolver roadmap entry now references both ADRs as accepted with the two-schema-then-resolver phasing. | ## Notes for the reviewer - **ADR-0025's bullet got a small touch-up, not a rewrite.** The original copy listed scope kinds as `etablissement:<finess>`, which was accurate when ADR-0025 shipped but is now superseded by ADR-0027's `Structure.code` semantics (FINESS for medico-social rows, internal slugs otherwise). The change is `<finess>` → `<structure-code>` + a `see ADR-0027` parenthetical. No actual decision in ADR-0025 changes. - **Two new Architecture bullets, mirrored on the ADR-0024 / ADR-0025 pair of bullets that precede them in tone + length.** The "Portal-side identity model" bullet calls out the `entraOid`-only v1 dedup and the non-unique `Person.email` (both decisions made during the split rework); the "Portal-side organisational hierarchy" bullet calls out the `Structure.code` round-trip semantics and the deferred-to-ADR-0028 items (`Pole`, `Service`, arbitrary nesting, per-source enrichment, full cascade sync). - **No code changes**, so no `pnpm ci:check` impact. `pnpm exec prettier --check` clean on the four touched files. ## Test plan - [x] `pnpm exec prettier --check` — clean on the four touched files. - [x] Internal links resolve (ADR-0026 ↔ ADR-0027 mutual references, plus the `ADR-0028` dangling marker left intentional for the future sync ADR). - [ ] **Review focus** — the two new Architecture bullets phrasing; the ADR-0025 bullet's small scope-literal touch-up; CLAUDE.md roll-up wording. ## What's next Now unblocked — per ADR-0026 §"Phasing" and ADR-0027 §"Phasing": 1. **ADR-0027 Implementation PR 1** — `Region` / `Delegation` / `Structure` Prisma schema + inline reference-data migration (Région Nouvelle-Aquitaine + Délégation 33 + a handful of test-tenant structures) + `Structure.kind` catalogue + drift-gate extension. Independent of (2) at the schema level. 2. **ADR-0026 Implementation PR 1** — `Person` / `User` / `UserScope` Prisma schema + `PersonAndUserProvisioner` called from `SessionEstablisher` + `Person.source` catalogue + drift-gate extension + updated `PrincipalBuilder` populating `Principal.user.{id, personId}` from the real rows. Can ship in parallel with (1). 3. **ADR-0026 Implementation PR 2** — `PrismaScopeResolver` replacing `StubScopeResolver` + `/admin/users/:id/scopes` admin-app screen + `prisma/seed.ts` populating the 19 test personas' `user_scopes` per `notes/test-tenant-role-assignments.md`. Depends on both (1) and (2). 4. **ADR-0028 (proposed)** — Pléiades + Acteurs+ + cascade syncs + facet schemas (Salarié / Élu / Adhérent / Bénévole / Bénéficiaire / PartenaireExterne) + operator-confirmed Person-reconciliation flow + the deferred org-hierarchy extensions (`Pole`, `Service`, per-source enrichment). --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #219
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.
