dtpr@2026-09-01-beta reads for sensors as well as AI systems. Category and element descriptions that said "this AI system" or "the AI" now say "this system", so a disclosure for a plain data-collecting device reads correctly: 73 English strings across purpose, accountable, risks, rights, input and output data, processing, access, retention and storage. Processing elements open with "Techniques that…" rather than "AI systems that…". right_to_notice is retitled Right to Be Informed and covers data collection as well as automated decisions. The input_dataset description no longer mentions training data. Wording left over from the device taxonomy ("data collection activity", "data collector") is generalized the same way. All ten translations follow.
Two risks for data-collecting systems. privacy_loss (Loss of privacy) and security_breach (Security & data breach) join risks_mitigation, each with its own symbol. The version now has 139 elements and 472 composed icons. References: Taxonomy.
dtpr@2026-09-01-beta adds Dutch and German. nl and de join the version's locales for all 377 localized strings, machine-translated and independently machine-reviewed. ?locales=nl and ?locales=de select them, and region tags resolve (nl-BE → nl, de-AT → de). Both are machine_reviewed; the open term and layout questions are listed in the translation status. References: GET /schemas/:version/translations.

Translation status is served by the API. GET /schemas/:version/translations and the get_translation_status MCP tool report how far each locale of a schema version has been reviewed (source, unverified, machine_draft, machine_reviewed, human_reviewed) and list the questions translators and reviewers flagged, each with targets naming the element, category or datachain type it concerns. The data is review metadata kept outside content_hash, so settling a flag does not look like a taxonomy change. References: GET /schemas/:version/translations, get_translation_status.

dtpr@2026-09-01-beta — consolidated datachain type (#326) The ai and device taxonomies merge into a single dtpr type, so the version prefix moves from ai@ to dtpr@ and every category's datachain_type follows. Content carries over from ai@2026-08-24-beta: 137 elements across 14 categories, with collection (capture technology) and manifestation (the form the output takes when people encounter it) holding the device-side concepts. The data_flow subchain is collection → input_dataset → processing → output_dataset → manifestation. The ai@ line is superseded and receives no further versions; versions already published under it stay served, so pinned consumers keep resolving. References: Versions & releases, Taxonomy.
Icon overhaul across five categories. collection and manifestation get 15 literal device/encounter glyphs in place of borrowed symbols; the five rights elements that shared one target glyph get distinct action glyphs; 10 legacy fine-line composites are redrawn as single bold objects legible at 36px. Icon counts are unchanged — 468 composed icons. References: Icon composition, Symbols.

Version selector spans the rename. The taxonomy and datachain surfaces list both dtpr@ and ai@ versions in one selector, newest first, so the lineage stays browsable across the type id change.

prompts/ capability — Agent Skills served over MCP. The MCP server now registers each of the seven DTPR Agent Skills (and the two shared reference documents) as named MCP prompts. Any MCP-aware client (Cursor, Continue, Cline, Claude Desktop, the Anthropic Agent SDK, custom clients) can list and load them via prompts/list + prompts/get without a Claude-specific install. Bundled at build time from plugin/dtpr/skills/ — single source of truth shared with the Claude plugin install path.
- New CLI: pnpm --filter ./api bundle:skills regenerates api/src/mcp/prompts/skills.generated.ts.
- Drift detection: pnpm test:plugin fails if a skill or reference exists in the plugin tree but not in the API bundle (or vice versa).
- References: Prompts, Other harnesses.

Plugin v0.3.0 — symbol-design split + seven-skill studio. Symbol drafting moves out of dtpr-element-design into a dedicated dtpr-symbol-design skill that proposes three SVG variants per round with a local HTML preview. The plugin docs also pick up the previously-undocumented dtpr-translate skill from 0.2.1, so the public skill table now lists all seven peers. References: Skills, dtpr-symbol-design, dtpr-translate.

Icon composition pipeline (#270) Shape × symbol × variant composition with default / dark / context-colored variants and the WCAG innerColor rule. Adds pre-baked R2 point-read with on-the-fly fallback. New REST routes: GET /api/v2/shapes/:shape.svg, GET /api/v2/schemas/:version/symbols/:symbol_id.svg, GET /api/v2/schemas/:version/elements/:element_id/icon[.<variant>].svg. New MCP tool: get_icon_url. References: Icon composition, REST icon routes.

dtpr.ai microsite placeholder (#271) Docus + Nuxt 4 skeleton deployed on Cloudflare Workers with a D1 binding for content queries. Minimal landing; no documentation yet.

Component library + render_datachain MCP tool (#267) Three subpath exports: @dtpr/ui/core (10 framework-neutral helpers), @dtpr/ui/vue (6 Vue 3 SFCs), @dtpr/ui/html (SSR via renderDatachainDocument). Default stylesheet wraps everything in @layer dtpr and exposes a full CSS custom-property token set. New MCP tool: render_datachain. New MCP resource: ui://dtpr/datachain/view.html (MCP Apps iframe handoff). References: Vue reference, Core reference, HTML SSR, Theming.

Read path on Cloudflare Workers (#265) Hand-rolled JSON-RPC over HTTP handler (workerd nodejs_compat can't load the SDK's CJS Ajv dep). Supported methods: initialize, notifications/initialized, tools/list, tools/call, resources/list, resources/read, ping. Shared ok / err envelope with _meta.content_hash / _meta.version. Initial tools: list_schema_versions, get_schema, list_categories, list_elements, get_element, get_elements, validate_datachain. References: Connecting, Envelope.

api.dtpr.io/api/v2 read path (#265) Public, read-only JSON + SVG. Opaque cursor pagination (MAX_LIMIT = 200), field/locale projection, DTPR-Content-Hash + Cache-Control on version-scoped responses, static CORS allow-list. POST /schemas/:version/validate runs shape + semantic validation and always returns HTTP 200. References: REST v2, Pagination & fields, Errors.

Standalone API scaffold + AI content migration (#262) Extracts DTPR content from the v1 site into a standalone API workspace. Establishes the schema authoring flow and migrates the ai datachain type.
CI: build @dtpr/ui + api/schema before typecheck (#268) Orders deploy workflows so generated types land before typecheck runs.
Drafting CLI + preview deploys + Claude Code plugin (#266)

Nuxt Studio with Google + GitHub OAuth (#269) Enables in-browser authoring for the existing v1 docs.
