Stacked on #53 (shared NSID validator). Merge that first.

Adds org.hypercerts.context.getCommentCounts, so clients can show comment counts for a list of posts in one call.

Changes

  • New query: 1–100 repeated subjects AT-URIs, returns { counts: [{ subject, commentCount }] } in request order with duplicates kept. A comment is an org.hypercerts.context.attachment with contentType: "comment" whose subjects[].uri matches; CID is ignored and the subject need not be indexed. It counts comment records, not authors.
  • One SQL statement, reusing listAttachments' safe subjects[] expansion; malformed records neither count nor fail the query.
  • lua/shared/subjectRecordUri.lua replaces three identical subject-URI checks (getCommentCounts, getEntityFollows, getActorReactions). followBatch.lua allows a missing actor (same change as the pending getFollowerCounts branch).
  • The listAttachments pagination HTTP test is scoped to its own publishers, since it assumed it owned every seeded attachment.
  • Docs, explorer snapshots, generated client, bundled skill and a changeset (both packages minor).

Known limits

  • "comment" is not yet a known contentType in the pinned @hypercerts-org/lexicon 2.0.0; it is merged upstream (hypercerts-lexicon#279) but unreleased.

Summary by CodeRabbit

  • New Features
    • Added a way to retrieve comment counts for up to 100 records in one request. Results follow the order of requested records, include repeated entries, and count matching comments regardless of subject CID. Only comment attachments are counted; records with no matching comments return a count of zero.
  • Bug Fixes
    • Requests with malformed percent escapes in subject DIDs are now rejected by entity-follow and reaction endpoints.
    • Corrected request-size calculations for batch follow queries when an actor parameter is omitted.

RetriggerView in GreptileConfidence Score: 5/5

The PR appears safe to merge after its stated dependency, PR #53.

Summary

Adds org.hypercerts.context.getCommentCounts for ordered batches of subject URIs.

  • Clients can fetch comment counts for many subject records at once.
  • Entity follows and actor reactions reject subject DIDs with malformed percent escapes.

Reviews (5) · Last reviewed commit: "Merge branch 'main' into context/get-com..." · Reviewed by Greptile

Counts current comment attachments (contentType "comment") per subject URI
for up to 100 subjects in one statement, counting records rather than
authors and ignoring subject CIDs.

Shares one subject-URI validator across getCommentCounts, getEntityFollows
and getActorReactions, and scopes the listAttachments pagination HTTP test to
its own publishers so other attachment fixtures cannot break it.

Walkthrough

Adds org.hypercerts.context.getCommentCounts for ordered comment-attachment counts by subject AT-URI. The change also centralizes subject URI validation in related endpoints, adjusts follow-query request-target sizing, and adds API documentation and tests.

Changes: Comment counts

Layer / File(s) Summary
Query contract and API registration
happyview-modules/lexicons/*, docs/sources/*, packages/api/src/lexicons/org/hypercerts/context*, docs/openapi.json, .agents/skills/hypercerts-api/references/*, docs/coverage.json, happyview-modules/README.md, .changeset/batch-comment-counts.md
Defines getCommentCounts inputs, output, and errors. Registers and documents the query in API types, lexicons, OpenAPI snapshots, and endpoint indexes.
Query handler and module wiring
happyview-modules/lua/endpoints/getCommentCounts.lua, happyview-modules/lua/src/getCommentCounts.lua, happyview-modules/modules/context-attachments/manifest.json, happyview-modules/manifest.json
Validates subjects and request size, queries PostgreSQL for distinct matching comment records, and returns ordered counts. Registers the endpoint and its assets.
Shared URI validation and follow-query sizing
happyview-modules/lua/shared/subjectRecordUri.lua, happyview-modules/lua/endpoints/getActorReactions.lua, happyview-modules/lua/endpoints/getEntityFollows.lua, happyview-modules/lua/endpoints/getReactionCounts.lua, happyview-modules/lua/shared/feedActorReactions.lua, happyview-modules/lua/src/getEntityFollows.lua, happyview-modules/lua/src/getReactionCounts.lua, happyview-modules/lua/endpoints/getFollows.lua, happyview-modules/lua/shared/followBatch.lua, happyview-modules/modules/entity-follow/manifest.json, happyview-modules/modules/feed-reactions/manifest.json
Adds shared subject-record URI validation, including DID percent-escape checks, and uses it in reaction and entity-follow queries. Follow batch request sizing counts the actor parameter only when present.
Fixtures and endpoint validation
happyview-modules/tests/http/fixtures/comment-counts.fixture.js, happyview-modules/tests/http/comment-counts.http.test.js, happyview-modules/tests/unit/tooling/comment-counts.test.js, happyview-modules/tests/http/context-attachments.http.test.js, CONTRIBUTING.md
Adds fixtures and tests for counting, duplicate inputs, invalid subjects, and query failures. Filters pagination test requests to fixture publishers and updates the documented coverage list.

Base automatically changed from lua/share-nsid-validation to main November 10, 2026 13:29
valid_did allows a bare or non-hex % escape, so getCommentCounts,
getEntityFollows and getActorReactions accepted subjects such as
at://did:web:example%GG/... while getReactionCounts rejected them. Move
getReactionCounts' escape check into the shared valid_subject_record_uri and
use that helper from all four endpoints.
