Julien Gautier 312791b74e docs: add docs/architecture.md with C4 contexts, Nx boundaries, and CI/CD pipeline
Cross-cutting visual reference for the architecture, written in
Mermaid (text in markdown, rendered natively by Gitea / GitHub / IDE
viewers, diffable in PR). Four diagrams that summarise decisions
spread across multiple ADRs:

1. C4 level 1 - System Context. The portal as a black box with its
   workforce/customer/IT/RSSI actors and Entra ID + downstream APIs
   as external systems. Customer audience and Entra External ID are
   shown dashed (future scope per ADR-0008's dual-audience design).

2. C4 level 2 - Containers. Browser-side portal-shell, on-prem BFF,
   Postgres (public + audit schemas), Redis, local OTel Collector,
   plus external Entra ID and downstream APIs. Annotates the wire
   protocols (HTTPS + __Host- cookies, OIDC, OBO/signed assertion,
   OTLP, ioredis with AES-GCM at rest, traceparent end-to-end).

3. Nx module boundaries. The Project graph rendered with the
   depConstraints from ADR-0003 (scope axis: portal-shell /
   portal-bff / shared, plus type axis: app / feature / shared).
   Forbidden directions called out below the diagram.

4. CI/CD pipeline. Local hooks → push → PR → 5 parallel CI jobs
   (check / scan / commits / perf / a11y) → branch protection →
   squash-merge → tag → release. Includes the weekly scheduled
   security-scheduled.yml workflow (full-tree scan + prod
   Lighthouse).

Convention adopted at the top of architecture.md: cross-cutting
diagrams live here; single-ADR diagrams live inline in the ADR
itself (sequence flows, ERDs, lifecycle diagrams, etc.). The 'To be
added' section at the bottom maps each future diagram to where it
will land and what triggers its addition.

docs/README.md index updated with a new 'Architecture' section
linking to architecture.md, and the previous empty 'Architecture'
placeholder removed (the placeholder was a tick-the-box section
that violated the doc convention 'documentation when genuinely
useful, not just to tick a box').

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.

Sections

Daily development

  • development.md — repo layout, prerequisites, initial setup, daily commands, conventional commit cycle. Day-to-day reference for working on the project.

Architecture

  • architecture.md — cross-cutting Mermaid diagrams: C4 system context, C4 containers, Nx module boundaries, CI/CD pipeline. Single-decision diagrams (auth sequence, ERD, etc.) live inline in their ADR.

Onboarding & environment

Setup guides for new contributors:

Operations & runbooks

Empty — to be populated when we deploy.

Security, performance, accessibility

Empty — placeholders to be filled with rationale docs alongside their corresponding ADRs.
