 # @hypercerts-org/lexicon
 
+## 0.11.0
+
+The v0.11.0 release introduces EVM identity linking, stronger type safety across badge and funding schemas, vendored Leaflet lexicons for runtime validation, and a set of schema refinements based on real-world usage from the first month of v0.10.0 adoption. All changes listed below are merged to `main` and will ship together as a single coordinated release.
+
+```bash
+npm install @hypercerts-org/lexicon@0.11.0
+```
+
+---
+
+### New lexicons
+
+#### EVM identity linking
+
+`app.certified.link.evm`
+
+A new record type for creating verifiable links between ATProto identities and EVM wallet addresses. Each record contains a cryptographic proof — currently EIP-712 typed data signatures for EOA wallets — that binds a DID to an Ethereum address on-chain.
+
+The `proof` field is an open union, so future signature methods (ERC-1271, ERC-6492) can be added without breaking existing records.
+
+```jsonc
+{
+  "address": "0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B",
+  "proof": {
+    "$type": "app.certified.link.evm#eip712Proof",
+    "signature": "0x...",
+    "message": {
+      "did": "did:plc:abc123",
+      "evmAddress": "0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B",
+      "chainId": "1",
+      "timestamp": "1711929600",
+      "nonce": "0",
+    },
+  },
+  "createdAt": "2026-04-03T00:00:00.000Z",
+}
+```
+
+#### Vendored Leaflet and richtext lexicons
+
+`pub.leaflet.*` · `pub.leaflet.richtext.facet`
+
+The package now ships the full set of Leaflet block and richtext facet lexicon JSON files (17 files). Previously, these external schemas were shimmed at the TypeScript type level via `@atcute` packages, which caused `LexiconDefNotFoundError` at runtime when validating records with `description` or facet fields. Vendoring them fixes runtime validation and removes the `@atcute/leaflet` and `@atcute/bluesky` dependencies.
+
+This is a **packaging change**, not a schema change. No record structures are affected.
+
+---
+
+### Breaking changes
+
+This release includes three breaking schema changes. All were identified early enough in adoption that the team decided the long-term gains outweigh the migration cost.
+
+#### Evaluation scores are now strings
+
+`org.hypercerts.context.evaluation`
+
+The `min`, `max`, and `value` fields on evaluation scores changed from `integer` to `string`. ATProto has no native decimal type, and integer-only scores made use cases like "3.7 out of 5" impossible.
+
+```diff
+  // Before
+- { "min": 0, "max": 10, "value": 7 }
++ // After
++ { "min": "0", "max": "10", "value": "7.5" }
+```
+
+**Who needs to update:**
+
+| Consumer | Action                                                                                                                 |
+| -------- | ---------------------------------------------------------------------------------------------------------------------- |
+| Indexers | Change column type from `INTEGER` to `TEXT`. Backfill existing records. Update any numeric sorting or filtering logic. |
+| AppViews | Parse scores as strings. Use `parseFloat()` for numeric display where appropriate.                                     |
+| Frontend | Handle both numeric strings (`"3.7"`) and potentially non-numeric strings (`"A+"`) in display components.              |
+
+#### Badge references are now strong refs
+
+`app.certified.badge.award` · `app.certified.badge.response`
+
+Badge awards and responses now reference their parent records via `com.atproto.repo.strongRef` instead of plain lexicon refs. Strong references include both a URI and a content hash (CID), pinning the reference to a specific version of the badge definition. This prevents the meaning of an award from drifting if the underlying badge definition is later modified.
+
+```diff
+  // Before
+- "badge": "at://did:plc:abc/app.certified.badge.definition/123"
+
+  // After
++ "badge": {
++   "uri": "at://did:plc:abc/app.certified.badge.definition/123",
++   "cid": "bafyrei..."
++ }
+```
+
+**Who needs to update:**
+
+| Consumer      | Action                                                                                                            |
+| ------------- | ----------------------------------------------------------------------------------------------------------------- |
+| Indexers      | Update parsing to expect `{ uri, cid }` objects instead of plain URI strings for `badge` and `badgeAward` fields. |
+| AppViews      | Update resolution logic. Dereference using both `uri` and `cid` for content verification.                         |
+| SDK consumers | Regenerate types. Any code constructing badge awards or responses must supply the full strong ref.                |
+
+#### Funding receipt fields normalized
+
+`org.hypercerts.funding.receipt`
+
+The `from`, `to`, and `for` fields have been reworked for consistency and stronger type safety.
+
+| Field  | Before (v0.10.0)  | After                                                                                      |
+| ------ | ----------------- | ------------------------------------------------------------------------------------------ |
+| `from` | Required, DID ref | **Optional**, union of `#text` \| `app.certified.defs#did` \| `com.atproto.repo.strongRef` |
+| `to`   | Plain string      | Union of `#text` \| `app.certified.defs#did` \| `com.atproto.repo.strongRef`               |
+| `for`  | AT-URI string     | `com.atproto.repo.strongRef` (pins to a specific record version)                           |
+
+The `from` and `to` fields were asymmetric — `from` required an AT Protocol identity while `to` accepted any string. Now both are three-way unions that accept a free-text string (`#text` — for display names, wallet addresses, or other identifiers), a DID, or a strong reference. This treats senders and recipients uniformly while preserving the ability to reference non-ATProto participants. `from` is also optional, properly supporting anonymous funding. `for` is now a strong ref, ensuring the receipt always points to the exact version of the activity it funded.
+
+```diff
+  // Before
+- "from": { "$type": "app.certified.defs#did", "did": "did:plc:sender" },
+- "to": "did:plc:recipient",
+- "for": "at://did:plc:abc/org.hypercerts.claim.activity/123"
+
+  // After — with a DID
++ "from": { "$type": "app.certified.defs#did", "did": "did:plc:sender" },
++ "to": { "$type": "app.certified.defs#did", "did": "did:plc:recipient" },
+
+  // After — with a free-text identifier
++ "to": { "$type": "org.hypercerts.funding.receipt#text", "value": "0xAb58...eC9B" },
+
+  // After — for field
++ "for": {
++   "uri": "at://did:plc:abc/org.hypercerts.claim.activity/123",
++   "cid": "bafyrei..."
++ }
+```
+
+**Who needs to update:**
+
+| Consumer      | Action                                                                                                                                                         |
+| ------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Indexers      | Update parsing for `from`, `to` (now unions with `$type` discriminator — handle all three variants), and `for` (now `{ uri, cid }`). Allow `NULL` for `from`.  |
+| AppViews      | Update resolution logic for all three fields. `for` requires dereferencing via both URI and CID. Handle `#text` variants for display.                          |
+| SDK consumers | Regenerate types. Code constructing receipts must supply union-typed `to` and strong ref `for`.                                                                |
+| Frontend      | Update forms to construct proper union objects for sender/recipient. Handle `#text` for non-ATProto participants. Handle missing `from` for anonymous display. |
+
+---
+
+### Schema changes
+
+> **A note on "optional" fields:** Even new optional fields require attention from indexers and AppViews. If an indexer doesn't store a new field, that data is silently lost for every downstream consumer. The changes below are non-breaking in the strict sense — existing records remain valid — but ignoring them means incomplete data.
+
+#### Known values
+
+Several free-text string fields now declare `knownValues` — a set of canonical values that establish interoperability conventions across the ecosystem. Custom values are still permitted. Think of these as Schelling points, not constraints.
+
+| Lexicon                             | Field         | Known values                                                                                       |
+| ----------------------------------- | ------------- | -------------------------------------------------------------------------------------------------- |
+| `org.hypercerts.collection`         | `type`        | `favorites` · `project` · `portfolio` · `program`                                                  |
+| `org.hypercerts.context.attachment` | `contentType` | `report` · `audit` · `evidence` · `testimonial` · `methodology`                                    |
+| `app.certified.badge.definition`    | `badgeType`   | `endorsement` · `verification` · `participation` · `certification` · `affiliation` · `recognition` |
+
+**Action:** Indexers should index these values for filtering and categorization. AppViews and frontends can use them for dropdowns, search facets, and display grouping. No schema migration required — the underlying field type is still a string.
+
+#### Badge icon is now optional
+
+`app.certified.badge.definition`
+
+The `icon` field moved from `required` to optional. Not all badges have a visual representation — endorsements, participation records, and text-based certifications can now omit the icon entirely.
+
+**Action:** Indexers should allow `NULL` in the icon column. Frontend developers must add a fallback or placeholder when rendering badges without an icon — apps that assume `icon` is always present will crash or render broken UI.
+
+#### Contributors array is uncapped
+
+`org.hypercerts.claim.activity`
+
+Removed the `maxLength: 1000` constraint on the `contributors` array. ATProto records have a natural 1 MB size limit (~2,000–4,000 contributors), making the artificial cap unnecessary.
+
+**Action:** Indexers and AppViews with hardcoded length limits matching the old max should remove them. Frontends should implement pagination or lazy loading for large contributor lists to avoid performance issues.
+
+#### Rich text on collection short descriptions
+
+`org.hypercerts.collection`
+
+Added `shortDescriptionFacets` — an optional array of rich text facets (mentions, URLs, hashtags) that annotate the `shortDescription` field. This brings collections in line with activity claims, which already supported facets.
+
+**Action:** Indexers must store the new field when present — without it, rich text annotations (links, mentions) are permanently lost. AppViews should include facets in API responses. Frontends can render rich text using the standard ATProto facet model.
+
+---
+
+### Documentation improvements
+
+- **Contributor and item defs** now have descriptions, improving TypeScript IntelliSense and AI code generation.
+- **`occurredAt` vs `createdAt`** semantics clarified on funding receipts. `occurredAt` is when the funding happened in the real world; `createdAt` is when the record was written to the PDS.
+- **Stale references** in board and measurement lexicon descriptions have been corrected.
+- **README** rewritten with an ASCII namespace map and structured reference tables.
+- **AI agent skill** added for downstream developers. Install via `npx skills add hypercerts-org/hypercerts-lexicon`.
+
+---
+
+### Upgrading
+
+```bash
+npm install @hypercerts-org/lexicon@0.11.0
+```
+
+The source of truth for lexicon definitions is the [NPM package](https://www.npmjs.com/package/@hypercerts-org/lexicon) and the published ATProto repository. The `main` branch on GitHub is a development branch — do not build production applications against it.
+
+After upgrading, regenerate your TypeScript types and run your validation suite against the updated schemas. The package includes all lexicon JSON files and pre-built type definitions.
