Closes TECH-760.

Adds @hypercerts-org/sdk/badge: createBadgeDefinition, awardBadge and respondToBadgeAward.

Changes

  • awardBadge takes a new definition or an existing one by URI; a new definition is written in the same commit as the award.
  • The issuer allowlist is checked against the exact definition version referenced (omitted means anyone, [] means no one).
  • respondToBadgeAward accepts or rejects an award as its recipient (the subject DID, or the subject record's repo).
  • internal/media.ts exports its existing file check and upload wrapper (assertFileAllowed, uploadField) so badge icons reuse them; messages unchanged.
  • Skill reference, changeset, tests.

Summary by CodeRabbit

  • New Features
    • Added a badge API for creating definitions, awarding badges to accounts or records, and accepting or rejecting awards.
    • Added a dedicated badge import path and documentation covering badge inputs, issuer and recipient rules, and write outcomes.
  • Bug Fixes
    • Improved validation and error details for media uploads, including clearer reporting when files are rejected.

Walkthrough

This PR adds SDK APIs to create badge definitions, award badges to account or record subjects, and respond to awards. It adds a package subpath, validation and write handling, tests, and documentation for these operations.

Changes: Badge SDK APIs

Layer / File(s) Summary
Build and validate badge definitions
packages/sdk/src/badge/build-definition.ts, packages/sdk/src/internal/media.ts, packages/sdk/src/badge/create-badge-definition.test.ts
The definition builder validates inputs and icons, uploads icon blobs, and creates records. Shared media helpers validate files and wrap upload errors. Tests cover accepted and rejected inputs, uploads, and write outcomes.
Resolve award targets and submit awards
packages/sdk/src/badge/award-targets.ts, packages/sdk/src/badge/award-badge.ts, packages/sdk/src/badge/award-badge.test.ts
awardBadge resolves the subject before the definition, checks issuer permissions and validity dates, and submits the award with a new definition when applicable. Tests cover target resolution, validation, and write outcomes.
Validate recipients and create responses
packages/sdk/src/badge/respond-to-award.ts, packages/sdk/src/badge/respond-to-award.test.ts
respondToBadgeAward validates and reads the award, checks the authenticated account against the recipient, and creates a response. Tests cover response fields, recipient checks, and write outcomes.
Export and document badge APIs
packages/sdk/package.json, packages/sdk/src/badge/index.ts, .agents/skills/hypercerts-org-sdk/SKILL.md, .agents/skills/hypercerts-org-sdk/references/badge.md, .changeset/badges.md
The package exports the badge subpath. The skill guide, badge reference, and changeset describe the APIs and their documented constraints.

Merge Risk: Minimal · previous review 36eef

The new badge APIs show no concrete merge-blocking behavior risk. Fixing the rejection example in the badge reference and optionally sharing the record-type check are small follow-ups.

Not a real duplicate; leaving as-is. awardBadge and respondToBadgeAward both run the same outline (parse input, read what the record points at, prepareChecked, submitWrites), but every step differs: the award resolves a subject and a definition, checks issuers and validity, and may write two records; the response reads and validates an award, derives the recipient and writes one. The shared parts already live in internal/ (createBuildContext, parseInput, prepareChecked, submitWrites, readRecord). A common wrapper for the outline would only hide the differences. The semantic check is report-only (similarity ~0.75), and its docs say to share code only for real duplicates.

False match; leaving as-is. planDefinition reads a definition choice through toSlot and checks the signed-in account against allowedIssuers before anything is read or uploaded. planNew (internal/slots.ts) validates one record's input and plans its references. They share the parseInput call and nothing else, so there is no code to extract (semantic similarity ~0.57).

Valid, and a small real duplicate: assertAwardUri and parseCollectionUri (collection/create-activity-in-collection.ts) both run parseRecordUri, compare the collection and throw the same message. internal/slots.ts existing() has a third copy of the message. Sharing it means a new helper in internal/resolve-record-ref.ts that other domains use, so the head coordinator deferred it until after this stack merges. Not changed here; left open for you.

49-56: Trivial · Maintainability & Code Quality · Low value

Consider sharing the record-type check with create-activity-in-collection.ts.

jscpd reports this block as similar to code at packages/sdk/src/collection/create-activity-in-collection.ts:227. Both blocks parse a record URI and compare its collection with an expected NSID. A shared helper in internal/resolve-record-ref.ts would remove the duplicate. The error messages differ per operation, so the helper must take the operation name and the expected type. Defer this if the two messages must stay separate.

Extract the duplicated URI collection check into a shared helper in the
record-reference resolution module, and use it from assertAwardUri and the
corresponding collection-creation flow. Pass the operation name and expected
NSID into the helper, while preserving each caller’s operation-specific error
message and current validation behavior.

Add createBadgeDefinition, awardBadge and respondToBadgeAward at
@hypercerts-org/sdk/badge.

- awardBadge creates a new definition and the award in one applyWrites
  commit, or reuses an existing definition, and checks the signed-in
  account against that definition version's allowedIssuers.
- respondToBadgeAward only creates a response for the award's recipient:
  the account it is for, or the account whose repository holds the record.
- The icon is a raw blob field; its type and size are checked against the
  lexicon before upload.

TECH-760
Share the placeholder-blob type/size check and the wrapped upload error from internal/media.ts instead of keeping copies in build-definition.ts.
SonarCloud flagged the nested ternary in assertValidityRange. The message is unchanged.
