summary: >-
  Decision Anchor has no separate test environment, no test-mode keys and no separate host: production is the
  sandbox. What it publishes instead are three rehearsal mechanisms — a free Trial balance every new agent
  receives, a paid-at-a-fraction simulation layer (sDAC) that prices Execution Envelope combinations without
  creating a record, and free unauthenticated pricing endpoints plus GET-on-POST guidance documents that
  return a working example call. No fixture values are published, and none are invented here.
test_vs_live:
  separate_environment: false
  separate_host: false
  key_prefixes:
    auth_token: da_tk_
    recovery_key: da_rk_
    note: One key type; the prefixes distinguish credential kinds, not test from live.
  note: One host, one credential type. Trial-paid and externally-paid records are the same records — the difference shows in the response (status trial_paid vs pending_payment).
trial:
  grant: 500 DAC for 30 days, automatically on POST /v1/agent/register (no auth, no payment method)
  applies_to: ['POST /v1/dd/create', 'POST /v1/sdac/session/end', 'POST /v1/ise/exit']
  does_not_apply_to: 'ARA paid observation ("there is no trial fallback on this path"), bilateral propose, TSL purchase, ASA'
  check: 'GET /v1/trial/status (auth) — balance, expiry and the routes the trial covers'

simulation:
  name: sDAC (simulated DAC)
  operations:
  - 'POST /v1/sdac/session/start'
  - 'POST /v1/sdac/trial   # "Simulate EE combination (trial run)"'
  - 'GET /v1/sdac/session/{session_id}'
  - 'POST /v1/sdac/session/end   # settles; trial-eligible; $0.01 base via x402 otherwise'

  cost: >-
    "An identical-physics environment with accountability removed. The same cost function as the real cost
    structure applies, and a fraction (ratio-based) of the cost is actually paid. Not a free simulation."
    The ratio itself is not published in any surface found.
  leaves_records: false — "sDAC usage history does not leave accountability records in Core"
free_preflight:
  - operation: 'GET /v1/pricing/current'
    auth: none
    returns: base_fee 10 DAC, every EE axis add, multiplier rule, formula, earned_dac and asa parameters
  - operation: 'GET /v1/pricing/ee-presets'
    auth: none
    returns: 'EE_basic (10 DAC), EE_standard (45 DAC), EE_high (157.5 DAC) with their axis values'
  - operation: 'GET /v1/dd/create and GET /v1/agent/register (GET on the POST routes)'
    auth: none
    returns: how_to_call, curl_example, authentication and payment terms — a runnable minimal call
fixtures:
  test_values: none published
  example_ids_in_docs: 'AGENTS.md uses placeholder ids (00000000-0000-4000-8000-000000000000, e8b35dce-...) and placeholder credentials (da_tk_abc123..., da_rk_def456...) in its curl walk-through; these are illustrations, not usable test tokens'

payment_testing:
  network: Base mainnet only (eip155:8453) — no testnet is documented
  note: 'External payment cannot be rehearsed without real USDC; the Trial balance is the documented way to exercise the paid routes it covers.'
