javierandClaude Opus 5.5 911424de24 Project updates from Template
This commit contains the latest updates from the generic Website template, which move the toolchain to Swift 6.4, gate analytics and structured data behind traits, and rework page routing:

- Updated the Swift toolchain for all the package dependencies and the Website service to version 6.4. (345b305)
- Adapted all the existing middlewares in the Infrastructure package to Swift 6.4. (26008df)
- Moved test resource teardown in the Persistence and the Website library into defer blocks. (27984a9)
- Gated analytics behind a trait and reworked structured data in the Infrastructure package. (c7d4769)
- Enabled the Analytics trait in the Website service. (f6a6bbd)
- Reworked page routing in the Website service. (d1cb2c1)
- Gated the structured data features in the Infrastructure package behind a trait. (f0a8791)
- Enabled the StructuredData trait of the Infrastructure package in the Website service. (bbfdeb3)
- Fixed the asset pin and a build warning in the Dockerfile of the Website service. (6ed0f9b)

The root README change in 345b305 was left out, as this project no longer carries that file. From d1cb2c1, the RootController rework was left out, as the prototype serves a session-aware landing page and routes its other pages through their own controllers; the view-event reporter was appended to the prototype's shared script instead.

The prototype code was adapted to the stricter Swift 6.4 settings: `String(format:)` was swapped for safe formatting, the NoIndex middleware takes a `@concurrent` next handler, and the tests flagged by warnings-as-errors were tightened.

Localization

The server-side localization toolkit the platform's services build on: locale-explicit String Catalog lookups, Accept-Language negotiation, and the catalog-derived language list — with no dependencies beyond Foundation.

Overview

Role Types
Lookup Localize, a bundle-bound localizer that resolves a catalog key for an explicit locale
Negotiation Negotiate, which picks the best supported language from an explicit request or an Accept-Language header per RFC 9110
Languages LanguageList, the supported and default languages a bundle's String Catalog defines
Diagnostics CatalogState, the outcome of reading the catalog (loaded, missing, or undecodable)

Design rules

  • The String Catalog is the single source of truth. Supported languages, the default language, and every string come from the bundle's Localizable.xcstrings, so adding a language is a translation-only change.
  • The locale is always explicit. A server has no single "current" locale, so every lookup names the locale to resolve in; nothing reads process-wide locale state.
  • Raw .xcstrings parsing, for Linux parity. The catalog is decoded from its JSON rather than through Foundation's compiled-catalog APIs, which are unavailable or non-functional on Linux. Consumers must .copy the resource verbatim (never .process it) so it ships as raw JSON everywhere. Only simple stringUnit values are decoded — plural and device variations are not.
  • Resolution never fails. A missing entry falls back to the source-language string, then to the key itself; a missing or undecodable catalog degrades the language list to the default. Check catalogState at startup and warn when it is not .loaded.
  • Method structs. Localize and Negotiate hold their lifetime-fixed configuration (the bundle) in init and take only per-call inputs in callAsFunction.
  • One decoded catalog per bundle. Catalogs are immutable at runtime, so every Localize, Negotiate, and LanguageList bound to the same bundle and table shares one cached StringCatalog.

Layout

Sources are split by visibility, then by kind, one type per file:

Sources/
├── Public/
│   ├── Enumerations/      CatalogState
│   ├── Methods/           Localize, Negotiate
│   └── Types/             LanguageList
└── Internal/
    ├── Protocols/         CatalogResolving, the seam between the public API and the catalog backend
    └── Types/             StringCatalog (the cached .xcstrings decoder), LanguageRange
Tests/
├── Cases/                 the test suites, mirroring the Sources/ layout
├── Catalogs/              the String Catalog fixture, copied verbatim so it loads on Linux
└── Utils/                 the StubCatalog resolver and the suite Tag constants

Testing

Every suite carries a tag for the kind of API it exercises — .method or .type, declared in Tests/Utils/Extensions/Tag+Constants.swift — so test plans and summaries can slice a run by kind. A new suite adopts the tag matching its subject, or adds one when none fits.

Requirements

  • Swift 6.4 toolchain (swift-tools-version:6.4).
  • macOS 15, matching the sibling packages (the services deploy to Linux containers; the packages carry no UI platforms).
  • No package dependencies — Foundation and Synchronization only.
