Mercado Público

Operate the private Mercado Público supplier portal as a cautious copiloto operativo.

Quick start

1. Start from the authenticated supplier shell when possible:
   • https://www.mercadopublico.cl/Portal/Modules/Menu/Menu.aspx
2. Treat the site as hybrid:
   • legacy modules often load inside iframe fraDetalle
   • newer modules may open in separate routes or embedded apps
3. Prefer read / prepare / explain first.
4. Require explicit confirmation before any action that changes state.

Core workflow

1. Establish session

• Use ClaveÚnica flow when needed.
• Expect email OTP.
• Expect entity selection after login.
• If session already exists, reuse it instead of reauthenticating.
• Treat full broker automation as potentially fragile; prefer an already-authenticated session or manual fallback when the federated flow starts expiring or rejecting automation.

For details, read in this order:

• references/login-state-machine.md (siempre, para decidir estado/transición e intervención humana)
• references/auth-y-sesion.md (flujo base y señales de sesión)
• references/acceso-a-correo-otp.md (requisitos generales de acceso a correo OTP)
• references/otp-provider-contract.md (contrato esperado del proveedor OTP)

2. Route correctly

• Prefer entering through Menu.aspx.
• Inspect whether the target module lives in fraDetalle.
• If a direct URL returns 404, retry from the menu/iframe context before concluding the module is broken.
• Distinguish between:
  • legacy ASP.NET pages with postbacks
  • newer modules with separate routes / richer UI

For details, read:

• references/arquitectura-y-ruteo.md

3. Choose the task path

• Apply the business rule API first, portal after.
• Prefer the public API when it answers the question with enough fidelity.
• Use the private portal only when the API does not cover the case, when provider-specific authenticated context matters, or when a real portal action/review is required.
• Leer references/runbooks.md para ejecutar flujo operativo mínimo (buscar licitación, revisar ofertabilidad, revisar OC, preparar cotización, diagnosticar portal).
• Licitaciones → search, review detail, questions, attachments, offer readiness
• Órdenes de compra → search, inspect detail, identify allowed actions, XML/attachments/payments
• Cotizaciones / Trato Directo / Compra Ágil → inspect and prepare response flows up to pre-confirmation
• Reclamos → locate correct entry point, identify whether flow stays in portal or redirects to help center
• Gestión / reportería → summarize pending items, counts, and dashboards
• Diagnóstico → explain 404s, disabled buttons, null-reference errors, CAPTCHA, or context-sensitive failures

Read only the relevant reference file(s):

• references/api-publica.md (always first for discovery/reporting/search use cases and API-vs-portal decisions)
• references/licitaciones.md
• references/ordenes-de-compra.md
• references/cotizaciones-trato-directo-y-compra-agil.md
• references/reclamos-y-ayuda.md
• references/gestion-y-reporteria.md
• references/diagnostico-y-guardrails.md

Operating rules

• Prefer safe navigation from the logged-in shell over guessing deep links.
• Explain why an action is blocked when possible (estado hábil, role, timing, state, broken module).
• Separate:
  • leer
  • preparar
  • confirmar y enviar
• Stop and ask for confirmation before any irreversible or state-changing action.

Mandatory guardrails

Always require explicit confirmation before:

• sending an offer
• sending a quotation
• accepting or rejecting an order
• requesting cancellation
• submitting a complaint
• performing any action that changes procurement state, contractual state, or payment-related state

Never assume a visible button is safe to click just because it is present.

If the portal shows 404, NullReferenceException, a disabled action, or unexpected redirects:

• diagnose first
• explain the likely cause
• propose the next safe step
