summary: >-
  anew publishes a real, specific deprecation policy with named RFCs and a minimum notice period, which
  is unusual for a free single-purpose service. It publishes no status page and no changelog.

versioning:
  http_surface:
    scheme: unversioned-additive
    detail: >-
      /write and the page URLs have carried the same contract since launch. New behaviour arrives as a
      new negotiated representation (an Accept type) or a new response header — never as a change to an
      existing one. The provider explicitly advises integrating without a version pin.
  jsonrpc_surfaces:
    - endpoint: /a2a/v1
      scheme: path-versioned
      current: v1
    - endpoint: /mcp
      scheme: protocol-revision-negotiated
      supported:
        - '2026-07-28'
        - '2025-11-25'
      default_declared: '2025-11-25'
      unsupported_response: JSON-RPC -32022
      source: https://anew.page/.well-known/mcp.json
  error_codes:
    scheme: append-only
    detail: A code published in the OpenAPI Error enum is stable; codes are added, never repurposed.
  spec_version: '1.0.0'
  openapi_version: 3.1.1

deprecation_policy:
  published: true
  url: https://anew.page/llms.txt
  minimum_notice_days: 90
  currently_deprecated: none
  detail: >-
    "Nothing is deprecated today. When something is, it is announced in this file first, then signalled
    on the wire for at least 90 days before it stops working."
  wire_signals:
    - header: Deprecation
      standard: RFC 9745
      carries: the date it became deprecated
    - header: Sunset
      standard: RFC 8594
      carries: the date it stops working, never less than 90 days after the Deprecation date
    - header: Link
      rel: deprecation
      carries: a pointer to the explanation
  guidance_to_integrators: Integrate without a version pin; watch the Deprecation and Sunset headers.

status_page:
  published: false
  probed:
    - url: https://anew.page/status
      status: 404
  note: >-
    No status page, status subdomain or uptime feed was found. Nothing in llms.txt, the api-catalog
    linkset, agents.json or the GitHub repository points at one.

changelog:
  published: false
  note: >-
    No dated changelog is published anywhere on the site or in the GitHub repository, and the repository
    has no releases and no tags. The provider's substitute is the additive-only versioning promise plus
    llms.txt as the announcement channel of record. Recorded as an honest absence — changelog/ is
    deliberately not written.

sla:
  published: false
  note: >-
    None. The published terms state the service is provided "as is" without any liability
    (https://github.com/round/anew.page/blob/main/LICENSE.md).

durability:
  model: content-addressed-immutable
  detail: >-
    A page's bytes live in its URL, not on a server, so a minted URL does not depend on a stored record
    surviving. Every write is immutable and every edit mints a new URL that leaves the original working.
    The one server-dependent artifact is the best-effort .png screenshot twin, which is a cache.
  caveats:
    - >-
      Rendered pages rewrite absolute HTTP(S) img srcs to a signed /img/ proxy URL that stops resolving
      when the signing key rotates. The author's source bytes are unaffected — read with Accept
      text/plain to get them back exactly.
    - >-
      A page linking to a host later flagged by Cloudflare's or Google's threat feeds is refused with 451
      content_blocked, so serving is contingent on outbound link reputation.
