  pointers_not_emitted:
  - type: StatusPage
    reason: tailortech.statuspage.io — the status page Tailor's own security docs send customers to — reports "Page Inactive"
      and its API returns 401 "Your page is inactive". status.tailor.tech serves only the Statuspage app shell with every
      data endpoint 403. See lifecycle/tailor-lifecycle.yml.
  - type: TermsOfService
    reason: No terms page exists. /terms, /terms-of-service, /terms-of-use and /legal all 404, and the sitemap's 25 URLs contain
      no terms page. Only a privacy policy is published.
  - type: Pricing
    reason: /pricing 404s and no pricing page appears in the sitemap or either llms.txt. See plans/tailor-plans-pricing.yml.
  - type: Idempotency
    reason: 109 of 254 control-plane RPCs declare `idempotency_level = NO_SIDE_EFFECTS`, which is real machine-readable safe-retry
      metadata — but it covers reads only. No RPC declares IDEMPOTENT, no Idempotency-Key header exists, and "idempoten" appears
      zero times in Tailor's 2MB documentation corpus. Emitting the pointer would assert write idempotency Tailor does not
      provide. Recorded honestly in conventions/ instead.
  - type: AgentCard
    reason: /.well-known/agent-card.json and /.well-known/agent.json 404 on every Tailor host except console.tailor.tech,
      which answers 200 with its SPA shell for every path. No A2A card is published. Search-only artifact — nothing written.
  - type: Roadmap
    reason: No public roadmap page found on tailor.tech, docs.tailor.tech or the GitHub organization.
  - type: Postman
    reason: No public Postman collection or workspace found. The API is gRPC/Connect and GraphQL, not REST.
