# Status and limits

What is live on sponge.computer, what is still being verified, and the current limitations of the product.

Docs edition 2026.09. Reviewed 2 September 2026.

## What is live

What is implemented and live on sponge.computer today.

Public /k resolution is live. Knowledge records, reviewed editions, and release-gated read-only /k pages are readable without a session; authoring, review, and release controls require sign-in.

- Document proposals: Opt-in document proposals are live: with Propose changes on, an agent's document edits wait as ghost, diff, or struck blocks until the owner accepts, rejects, or edits them.
- Knowledge service and public pages: The graph-native knowledge service, reviewed editions, and release-gated read-only /k pages are live at sponge.computer. Public /k resolution is live.
- Agent API: The v1 agent API, revision-fenced semantic document mutations, durable research jobs, optional report-acceptance contracts, report export, the OpenAPI contract, the discovery manifest, and the downloadable skill are live. The live research pressure test reached its required human-review barrier.
- Documents: Versioned rich documents, durable history, bounded collaboration, visible agent plans, editable queued chat turns, native evidence files, and lossless recovery are live for signed-in workspaces.
- Blocks: Stable nested blocks, block-scoped collaboration, large-document outline search, and bounded agent edits are implemented.
- Markdown: Loss-aware Markdown import and export, canonical preview, issue reporting, and lossless recovery import and export are implemented.
- Citations: The authenticated Source and evidence picker, prose and code-block graph citations, safe rich paste, and public bibliography projection are implemented. Public citations show the source title, publication year, and kind when the research recorded them.
- Proposals and review: Agents can submit bounded knowledge proposals; humans claim, inspect, accept, reject, or return them, and separately propose public promotion.
- Ontology: The seven-concept kernel, typed values, versioned vocabularies, composable Shapes, and immutable graph records are implemented. No domain concept is a privileged root kind.
- Inquiries: Private Inquiry creation, durable graph bootstrap, research events, proposal review, and recovery are live for signed-in workspaces.
- Editions: Supported synthesis staging, human review, immutable finalization, explicit publication enablement, release, and public /k locators are implemented. A released edition page reads as an article titled by its question, with numbered passages, cited sources, a colophon, and a Markdown projection.
- Sharing: Every public surface requires an explicit, purpose-bound boundary; a review decision alone never makes knowledge public. Public /k locators bind an artifact identity to an exact graph revision or edition.

## What is still being verified

The journeys that work but are still under broader verification.

- Signed-in journeys: Signed-in review and publishing journeys are live; their authenticated end-to-end verification remains in progress.
- Browsers and devices: The editor's native browser and device matrix remains under broader verification.
- Examples: The tutorial and guides follow live authoring, review, citation, and edition workflows; the full authenticated browser and device matrix behind them is still being verified.

## Current limitations

Behavior that is deliberately limited today and what the limit means for you.

- Search and bearer review reads: POST /api/v1/search and GET /api/v1/reviews/{reviewRef} answer 503 TEMPORARILY_UNAVAILABLE without charging the request budget until their separate disclosure boundaries are activated. The search box on /k and on every edition page is live and searches released objects only.
- Standalone proposal submission: POST /api/v1/proposals answers 409 AGENT_RUN_REQUIRED; a knowledge proposal reaches review only through a live research job.
- Copies that contain citations: Whole-document and block copies containing citations currently stop before a copy is created. Lossless cited duplication will return when the new copy can establish its own verified citation authority.
- Acceptance contracts: The current CLI does not construct the optional acceptance object, so a client that needs it sends the report specification as JSON to the API.
- Public JSON: Exact released Entity, Inquiry, and Edition JSON remains anonymous and bound to one immutable revision; there is no public listing endpoint beyond the /k index, its feed, and the sitemap.
