The host organisation - APF France Handicap - was confirmed on 2026-04-30. Update all in-repo references to use apf_portal (snake_case in prose) and apf-portal (kebab-case workspace name and repo URL). Touched: CLAUDE.md, ADRs 0001/0002/0003/0015, and the Nx bootstrap setup guide. The historical name is preserved as a single sentence in ADR-0003 as a self-validating example of the function-prefixed naming convention designed exactly for this scenario - the apps (portal-shell, portal-bff) and the lib conventions (feature-<name>, shared-<scope>) were unaffected by the rename, which was the explicit point of ADR-0003. Memory state aligned out-of-band: project_adastra.md retired, project_apf_portal.md created with the expanded APF context (host org, health + financial data scope, ASVS L3 pending RSSI input, UI stack decision spartan-ng + CDK + Tailwind, expanded phase-3 status). Pending follow-ups (user-side, not in this commit): - rename the Gitea repo julien/adastra_portal -> julien/apf_portal - git remote set-url origin gitea@git.unespace.com:julien/apf_portal.git - optionally rename the local working directory ~/Works/adastra_portal/ -> ~/Works/apf_portal/

Use ADRs to record architectural decisions
Context and Problem Statement
Architecturally-significant decisions will be taken throughout the lifecycle of apf-portal. Without a written, durable trace of why a decision was made — context, drivers, alternatives, trade-offs — that knowledge fades within months. New contributors re-litigate settled debates, the rationale of constraints (security, performance, accessibility) gets lost, and reversing a choice later becomes risky because nobody remembers what it was protecting against.
How do we record decisions in a way that is light enough to be sustained, durable enough to outlive contributor turnover, and integrated into the development workflow?
Decision Drivers
- Preserve the why of each decision so future contributors can understand or revisit it without re-deriving it.
- Make architecture reviewable — both at the time of a decision and during retrospective audits.
- Keep the format light enough that writing an ADR isn't a bureaucratic deterrent.
- Live alongside the code in version control, so decisions evolve with what they govern.
- Match the project's stated values: high technical bar, no bricolage, security/performance/accessibility as first-class concerns whose rationale must be traceable.
Considered Options
- No formal records — rely on commit messages and tribal knowledge.
- External wiki / Confluence — decisions live outside the codebase.
- ADRs in markdown using the MADR 4.0.0 format, in-repo.
- ADRs in another format (Nygard, Y-Statement, Cockburn).
Decision Outcome
Chosen option: ADRs in markdown using MADR 4.0.0, stored in decisions/ at the repository root.
Conventions are defined in README.md:
- flat folder layout (no nested category folders);
- globally sequential 4-digit numeric prefix (
NNNN-kebab-title.md); - categorization via the
tags:field in the MADR frontmatter, drawn from a canonical vocabulary; - status lifecycle:
proposed→accepted→ optionallydeprecated/superseded by ADR-NNNN; - index maintained in README.md alongside any ADR change.
Consequences
- Good, because the why of every architecturally-significant decision is captured at the moment it is made and travels with the code.
- Good, because ADRs are reviewed via the normal pull-request flow — architecture becomes an explicit team conversation.
- Good, because MADR provides enough structure (drivers, options, trade-offs) without being heavy.
- Good, because flat-folder + tags scales better than nested category folders as the count grows.
- Bad, because writing an ADR adds friction; this must be balanced against the cost of not writing one.
- Bad, because the index is maintained manually until tooling or a CI check is added.
Confirmation
- Every change introducing or transitioning the status of an ADR updates the index table in README.md in the same commit.
- PR review explicitly checks for ADR proposal whenever a non-trivial decision is being introduced.
- (Future) A CI lint job validates filename pattern, frontmatter shape, and tag vocabulary.
