Feature: Response envelope handling
  The responder parses the model's JSON envelope and decides what the
  bot says, where, and whether staff is alerted. (SPEC-001)

  Background:
    Given a responder with history limit 10

  @ENV-01
  Scenario: Model answer reaches the user
    Given the model answers with answer "Hei! Velkommen." and answer_needed "true"
    When user "alice" sends "Hei bot" in channel "chat"
    Then the response answer contains "Hei! Velkommen."
    And the response is marked as needed

  @ENV-02
  Scenario: Suppressed answer stays silent
    Given the model answers with answer "irrelevant musing" and answer_needed "false"
    When user "alice" sends "talking to bob" in channel "chat"
    Then the response is not marked as needed

  @ENV-03
  Scenario: Staff note forces delivery
    Given the model answers with answer "Et oyeblikk!" and staff note "Guest at table 4 needs a waiter"
    When user "guest" sends "Can somebody help us?" in channel "chat"
    Then the response staff note is "Guest at table 4 needs a waiter"
    And the response is marked as needed

  @ENV-04
  Scenario: Direct messages are always answered
    Given the model answers with answer "Svar." and answer_needed "false"
    When user "alice" sends "hei" directly to the bot
    Then the response is marked as needed

  @ENV-05
  Scenario: Short-path rules skip the model
    Given a short-path rule for channels "spam.*" and users "bob.*"
    When user "bobby" sends "noise noise" in channel "spam-corner"
    Then the model was not called
    And the response is empty
    And the history contains the message from "bobby"

  @ENV-07
  Scenario: History is trimmed to the limit
    Given a responder with history limit 4
    And 6 prior history entries in channel "chat"
    And the model answers with answer "ok" and answer_needed "true"
    When user "alice" sends "hei" in channel "chat"
    Then the history length is at most 4

  @ENV-08
  Scenario: Markdown links are unwrapped
    Given the model answers with answer "Se [menyen](https://fjerkroa.example/meny) her" and answer_needed "true"
    When user "alice" sends "meny?" in channel "chat"
    Then the response answer contains "https://fjerkroa.example/meny"
    And the response answer does not contain "[menyen]"

  @ENV-09
  Scenario: Missing channel falls back to the message channel
    Given the model answers with answer "ok" and no channel
    When user "alice" sends "hei" in channel "kitchen-talk"
    Then the response channel is "kitchen-talk"
