Route map, API surfaces, runtime rules, and SEO ownership.

API Endpoints

Curated architecture-significant routes. Start with the Documentation Index for the full docs map, or go straight to the API Reference for the exhaustive HTTP contract.

Route Definition Model

Static route metadata is declared once in the folderized shared/lib/api-endpoints/ module surface (@shared/lib/api-endpoints). That shared descriptor list carries path, method, admin/cache/probe/status-action metadata, shared dynamic-admin path matching, plus the worker dependency-hydration hints needed for static routes. Worker route primitives now live in worker/src/routes/shared.ts, domain route arrays are split under worker/src/routes/, and worker/src/routes/registry.ts composes them into the dispatch map that worker/src/router.ts consumes for method validation and generic dispatch. Dependency hydration lives in worker/src/routes/dependency-hydrators.ts and stays exhaustive/keyed by EndpointDependency, so adding a new dependency without wiring hydration still fails at compile time instead of silently defaulting.

Cron trigger metadata follows the same single-source pattern. shared/lib/cron-jobs.ts remains the schedule authority, while shared/lib/scheduled-runner-registry.ts binds each cron expression to a symbolic scheduled-runner key that both the worker scheduler and scripts/check-cron-schedule-sync.ts consume. That keeps worker/wrangler.toml, shared cron metadata, and scheduled-runner dispatch in lockstep.

Shared runtime host/origin defaults live in shared/lib/runtime-origins.json and shared/lib/runtime-origins.ts. Frontend API-base inference, /_site-data/* Pages Functions, ops-host Pages Functions, worker self/probe URLs, and local static-export tooling should consume that shared source instead of embedding production origins ad hoc.

The Stablecoin Cemetery public dataset export is static Pages data, not a Worker API route. scripts/generate-cemetery-dataset.ts reads shared/data/dead-stablecoins.json and writes public/datasets/stablecoin-cemetery.json plus public/datasets/stablecoin-cemetery.csv during prebuild; npm run check:cemetery-dataset guards drift in CI.

The API integration artifacts follow the same static-export pattern. scripts/generate-postman-collection.ts writes public/postman/pharos-api.postman_collection.json plus public/postman/pharos-api.postman_environment.json, and scripts/generate-openapi-spec.ts writes public/openapi.json during prebuild; npm run check:postman and npm run check:openapi guard drift.

Worker cron refactors should place reusable stage contracts under worker/src/cron/shared/. The seed contract layer in worker/src/cron/shared/stage-contracts.ts defines the shared vocabulary for stage progress, abort results, and handoff context so large cron decompositions do not each invent incompatible result shapes.

Frontend Runtime And SEO Surface

  • Indexable route families include:
    • /
    • /coverage/
    • /chains/ and /chains/[chain]/
    • /stablecoin/[id]/
    • /stablecoins/
    • /stablecoins/[peg]/
    • /stablecoins/governance/ and /stablecoins/governance/[governance]/
    • /stablecoins/backing/ and /stablecoins/backing/[backing]/
    • /stablecoins/infrastructure/ and /stablecoins/infrastructure/[infrastructure]/
    • /compare/[slug]/
    • /digest/ and /digest/[date]/
    • /methodology/ and /methodology/*-changelog/
    • /docs/ and /docs/[slug]/ for the curated public documentation archive; the allowlist lives in shared/lib/public-docs.ts
    • /about/api/
    • /changelog/
    • major feature pages with standalone static copy (/start/, /upcoming/, /blacklist/, /depeg/, /liquidity/, /safety-scores/, /stability-index/, /yield/, /flows/, /dependency-map/, /cemetery/, /telegram/, /status/, /about/, /privacy/)
  • Tool roots intentionally marked noindex,follow:
    • /compare/
    • /portfolio/
  • Stealth/noindex public routes:
    • /funding/ (noindex,nofollow; static JSON-backed funding ledger, intentionally absent from sitemap/nav in v1)
  • Private operator routes marked noindex,nofollow:
    • /admin/
    • /api/admin/
  • Crawlable server-rendered link hubs now live on the digest archive, safety scores, liquidity, taxonomy landing pages, and stablecoin detail pages. These hubs are part of the static export and are what npm run seo:check validates for orphan routes, sitemap coverage, and click depth.
  • /llms.txt is generated during prebuild from checked-in route/data sources as a curated LLM-facing index. It is a community proposal/inference aid, not a robots or sitemap replacement.
  • Markdown content negotiation for agents is handled by functions/_middleware.ts for /methodology/, /stablecoin/<id>/, /changelog/, /digest/<date>/, and /docs/*. The .md variants are generated by scripts/generate-markdown-exports.ts during postbuild and are written as out/<route>/index.md. Responses include Vary: Accept plus CDN no-store headers because Cloudflare's default CDN cache does not key on arbitrary Vary: Accept.
  • Cloudflare Pages static headers live in public/_headers. HTML routes use Cache-Control: public, max-age=0, s-maxage=300, stale-while-revalidate=86400; static assets with their own cache policy detach the broad rule with ! Cache-Control so Pages does not comma-join duplicate values.

Runtime host and env rules

  • src/lib/api.ts is the frontend runtime source of truth for API origin selection.
  • NEXT_PUBLIC_API_BASE is an optional explicit override, mainly for local next dev against wrangler dev.
  • When NEXT_PUBLIC_API_BASE is unset, buildRequestUrl() maps public browser reads on pharos.watch, ops.pharos.watch, and *.stablecoin-dashboard.pages.dev to same-origin /_site-data/*, while buildApiUrl() still points explicit public-API callsites (for example feedback and OG fetches) at https://api.pharos.watch.
  • functions/_site-data/[[path]].ts is the browser-facing proxy contract for the website data lane. It accepts only GET, allowlists public-read routes through shared/lib/site-data-routes.ts, requires SITE_API_ORIGIN on the production Pages hosts (pharos.watch, ops.pharos.watch), and still allows preview/local rehearsal to fall back to https://api.pharos.watch when that origin is intentionally unset. That fallback is useful only for exempt routes, auth-off/report-only rehearsals, or proxy setups that also forward a valid API key; protected public routes on production api.pharos.watch do not accept only X-Pharos-Site-Proxy-Secret. All normal site-data upstream requests use SITE_API_SHARED_SECRET against site-api.pharos.watch or a Worker preview URL.
  • site-api.pharos.watch is an internal Worker host, not a browser surface. worker/src/handlers/http/gates.ts allows only GET allowlisted site-data paths plus the shared-secret header on that lane (or on Worker preview URLs during CI rehearsal).
  • NEXT_PUBLIC_GA_ID gates GA4 script injection in src/app/layout.tsx. When it is unset, the site still renders normally and no browser analytics events are emitted from src/lib/analytics.ts.

Metadata and crawl ownership

  • src/lib/page-metadata.ts is the shared helper for per-route canonical metadata, Open Graph images, Twitter cards, and sentence-aware description trimming.
  • src/app/layout.tsx owns the sitewide metadata baseline, icons, api.pharos.watch preconnect, and root JSON-LD (WebSite, Organization, Person, WebApplication) with stable #website, #organization, #person-tokenbrice, and #webapp anchors. It intentionally does not emit SearchAction until the site has a real query handler.
  • src/app/sitemap.ts owns sitemap output for indexable routes. /compare/, /portfolio/, /funding/, and /admin/ are omitted; /compare/[slug]/ static comparison pages are included. LAST_EDITED dates are auto-generated from git history during prebuild (scripts/generate-sitemap-dates.ts) and written to a generated JSON file (gitignored). Public docs use scripts/generate-docs-metadata.ts for git-derived first/last modified dates.
  • src/app/robots.ts publishes an allow-all crawl policy, explicit AI crawler allow groups, disallows for operator surfaces (/admin, /admin/, /api/admin, /api/admin/), and the sitemap location.

CSS Build Pipeline

Styling runs through PostCSS with the @tailwindcss/postcss plugin (configured in postcss.config.mjs). This is the Tailwind CSS v4 integration path -- there is no standalone tailwind.config file; Tailwind v4 reads design tokens and @theme directives directly from src/app/globals.css. The cn() utility in src/lib/utils.ts uses tailwind-merge for safe class deduplication at runtime.

Reminder: Tailwind classes must be static strings -- never construct class names dynamically, as the CSS purge pass cannot detect them.


Worker Coding Conventions

Loose-equality null guard (!= null)

The worker codebase deliberately uses != null (loose equality) as the standard null/undefined guard for D1 query results. D1 can return either null or undefined for absent column values depending on the query path and column type, and value != null catches both in a single check. This is intentional -- do not "fix" these to !== null or !== undefined.


TypeScript Target Constraints

Both the root tsconfig and worker tsconfig target ES2022. Shared modules in shared/lib/ compile under both configs and may use ES2022 features (nullish assignment ??=, logical assignment ||=, Array.at(), top-level await, etc.) but must remain runtime-neutral — no DOM APIs, no Node-only APIs, no Cloudflare-only APIs.


Funding page

The /funding route is a static page backed by two hand-maintained JSON files in shared/data/funding/ (costs and donations). No cron, no D1, no API endpoint. Donations are appended to donations.json via the funding-update Claude skill on a weekly cadence — the skill researches inbound transfers to pharos-watch.eth across six chains (Ethereum/Base/Optimism/Arbitrum/Polygon via Alchemy alchemy_getAssetTransfers, Gnosis via Gnosisscan REST), prices each donation in USD at receipt via CoinGecko /coins/{id}/history, forward-verifies ENS, and writes after explicit user approval. See docs/funding-page.md for the data model and the rationale for the intentionally-simple architecture.
