"""FastAPI entry-point for the Incident Command Center environment.

Besides the OpenEnv contract endpoints (`/reset`, `/step`, `/state`, `/close`)
registered by `create_fastapi_app`, this module exposes:

- `GET /` and `GET /web` — interactive HTML dashboard.
- `GET /healthz` — liveness / readiness probe for orchestrators.
- `GET /version` — build metadata.
- `GET /metadata` — static environment metadata (action space, reward model).
- `GET /metrics` — lightweight in-process counters (best-effort).

The dashboard is written inline so the environment ships as a single
directory and can be embedded in Hugging Face Spaces without extra assets.

      <h2 style='margin-top:0'>🚨 The story in 2 minutes</h2>
      <p class='lede'>
        When a real tech company has an outage, <strong>three people's phones
        buzz at once</strong> — a Triage engineer, an Investigator, and an Ops
        Manager. They have to cooperate under a ticking <strong>SLA clock</strong>,
        every action costs <strong>budget</strong>, and every wrong call costs
        <strong>real money</strong> (enterprise outages hurt ~3× more than free-tier).
        <br /><br />
        We built a simulator of that war room — and we fine-tuned an LLM to run it
        <strong>as well as the human expert</strong>.
      </p>

      <h3 style='margin-top:1.25rem'>What is the environment?</h3>
      <p class='sub' style='margin:0 0 0.75rem'>
        Three specialist agents with <strong>different permissions</strong> resolve
        a live queue of 13 realistic tech incidents across 3 difficulty tiers.
      </p>
      <div class='table-wrap'>
        <table>
          <thead>
            <tr><th>Role</th><th>Can do</th><th>Cannot do</th></tr>
          </thead>
          <tbody>
            <tr>
              <td>🔍 <strong>Triage</strong></td>
              <td>Pull logs · check metrics · consult KB</td>
              <td>Close a ticket</td>
            </tr>
            <tr>
              <td>🧪 <strong>Investigator</strong></td>
              <td>Apply a fix · roll back a deploy</td>

      <h3 style='margin-top:1.25rem'>What did the agent learn?</h3>
      <p class='sub' style='margin:0'>
        Not "pick the right label." It learned a whole workflow — dig up clues,
        hand off to the right specialist, apply the correct fix, respect the SLA,
        file the post-mortem, close the ticket. The rubric makes every piece of
        that workflow <em>visible</em> as a named reward component, so you can
        see <em>why</em> the agent earned (or lost) points at every step.
      </p>

      <h3 style='margin-top:1.25rem'>Why it matters for the 3 hackathon themes</h3>
      <div class='grid grid-3'>
        <div class='card'>
          <h3>🤝 Theme #1 — Multi-Agent</h3>
          <p class='sub'>
            Three distinct roles with <strong>non-overlapping permissions</strong>.
            Wrong-actor calls → <code>-0.08</code>. Correct handoff → <code>+0.15</code>.
            Cooperation is <em>trained</em>, not hard-coded.
          </p>
        </div>
        <div class='card'>
          <h3>⏱️ Theme #2 — Long-Horizon</h3>
          <p class='sub'>
            Each episode runs <strong>3–5 sequential incidents</strong> over 20–60
            steps with a single ticking SLA clock. Big rewards (+0.80 × tier) only
            fire after clues → fix → post-mortem. Sparse and delayed by design.
          </p>
        </div>
        <div class='card'>
          <h3>🏢 Theme #3 — Professional World-Model</h3>
          <p class='sub'>
            Real logs, metrics, KB articles, red-herring signals, customer tiers,
            SLA timers, revenue impact. Close an enterprise ticket wrong and it
            hurts ~3× what a free-tier one does.
          </p>
