📝 Walkthrough

Walkthrough

The change adds Hypercerts Feed Service documentation, endpoint and procedure examples, pagination guidance, supported event kinds, reference links, and a Tools navigation entry.

Changes

Hypercerts Feed Service

Layer / File(s)	Summary
Service overview and feed retrieval pages/tools/hypercerts-feed-service.md	Documents the service, endpoints, XRPC procedures, request parameters, hydrated responses, supported event kinds, and invalid-record handling.
Skeleton feeds and cursor handling pages/tools/hypercerts-feed-service.md	Documents skeleton responses, opaque cursors, pagination scope, and cursor placement.
Reference and navigation integration pages/reference/certified-services.md, lib/navigation.js	Adds Feed Service endpoints and links to the reference page and Tools navigation.

Priority: ⬇️ Low — Defer this documentation change because it adds Feed Service pages, links, and navigation without changing product behavior.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 78eab

The new Feed Service documentation is ready with a minor staging-endpoint presentation inconsistency that could confuse users configuring staging access.

142-142: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use precise invalid-record and cursor semantics.

The first sentence repeats the previous review issue: “removes invalid entries rather than replacing them” does not state that invalid records are omitted without backfilling. The second sentence is also too broad. The service checks one extra row for lookahead, but the cursor is created from the last selected row before hydration. (github.com)

Proposed wording

-The hydrated endpoint validates source records and removes invalid entries rather than replacing them. A page can therefore contain fewer entries than its requested `limit`, while its cursor still advances over every source row the service checked.
+The hydrated endpoint validates source records and omits invalid entries without backfilling the page. A page can therefore contain fewer entries than its requested `limit`, while its cursor advances past the source rows selected before hydration.

127-127: 🗄️ Data Integrity & Integration | 🟡 Minor

Document all parameters that scope a cursor.

The text requires the same feedId but omits params.viewerDid, params.trustedEvaluators, params.organizationQuality, and params.kinds. If a client changes one of these values and reuses the cursor, pagination can skip or repeat records. State that clients must reuse a cursor with the same effective parameter values.

This repeats the cursor-scope finding from the previous review.

Proposed wording

-Keep cursors opaque and send them back only with the same `feedId`. Put `cursor` and `limit` at the top level of the request, not inside `params`.
+Keep cursors opaque. Reuse a cursor only with the same `feedId`, `params.viewerDid`, `params.trustedEvaluators`, `params.organizationQuality`, and `params.kinds`. Put `cursor` and `limit` at the top level of the request, not inside `params`.
