# Evaluation and scoring

> Agent Challenge lifecycle: prepare, deploy, Terminal-Bench cache, score gate, and BASE weights.

This page covers the submission lifecycle, score acceptance, and how results become BASE weights.

## Production path (mandatory)

Production scoring requires:

1. `phala_attestation_enabled` / `CHALLENGE_PHALA_ATTESTATION_ENABLED` **ON**
2. `attested_review_enabled` **ON**
3. Miner-driven Phala CPU TDX **review** CVM, then (only after fresh re-verified allow) **eval** CVM
4. Attestation-only grading: measured OpenRouter under review `.rules`; **no** Base LLM gateway on the scored path
5. Direct `POST /evaluation/v1/runs/{eval_run_id}/result` with score-domain attestation and durable key-grant

Validators do **not** deploy scored jobs for miners in production. Work-unit pull / `list_pending_work_units` style execution is legacy relative to the attested self-deploy path.

## High-level lifecycle

1. Miner signs and uploads an immutable ZIP (`POST /submissions`)
2. Digest becomes the stable agent hash; AST and similarity analysis may run as service gates
3. Attested **review** session: miner prepare/deploy measured review image; CVM produces domain-separated review report
4. Challenge verifies quote + review allowlist + review-domain `report_data` (bound times ≤24h)
5. Verdict: `allow` / `reject` / `escalate`
6. Miner **eval** prepare/deploy on separate measured **canonical** image (prepare refuses cache-only DB `review_allowed` bits)
7. Eval guest: GetTlsKey, RA-TLS golden key, trials from baked live-task-cache, attested RESULT
8. Accepted results may contribute to leaderboard and BASE raw weights

Public clients poll `GET /submissions/{id}/status` or SSE `GET /submissions/{id}/events`.

## Prepare / deploy / key-release / score gate

| Stage          | What must hold                                                                  | Fail closed when                                               |
| -------------- | ------------------------------------------------------------------------------- | -------------------------------------------------------------- |
| Review prepare | Signed assignment; immutable ZIP digests                                        | Signature / rate / capability failures                         |
| Review deploy  | Review allowlist `compose_hash`; Phala `encrypted_env` for OpenRouter + session | Missing encrypted\_env, GPU shape, money cap                   |
| Review result  | Review-domain quote + allowlist + bound times                                   | Stale >24h, wrong domain, measurement mismatch                 |
| Eval prepare   | Fresh re-verified allow materials (not DB phase alone)                          | `review_allow_required`, stale allow, cached-allow-only refuse |
| Eval deploy    | Canonical compose\_hash + measurement; plan nonces                              | Plan/compose mismatch, OS pin drift                            |
| Key release    | Raw TCP TLS 1.3 + client cert + keyrelease-domain quote + allowlist             | Deny returns no key; no L7 `/release` production path          |
| Score admit    | Score-domain quote + event log + allowlist + durable key-grant + nonces         | Missing key-grant or attestation materials write **no** score  |

## Public phases (attested mode)

Exact public strings can evolve. Conceptual map:

| Concern                | Phases / outcomes (illustrative)                                                                                                                                                                    |
| ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Review                 | `review_queued`, `review_cvm_running`, `review_provider_standby`, `review_verifying`, `review_allowed`, `review_rejected`, `review_escalated`, `review_expired`, `review_cancelled`, `review_error` |
| Eval                   | `eval_prepared`, `eval_running`, `eval_verifying`, `eval_accepted`, `eval_rejected`, `eval_expired`, `eval_cancelled`, `eval_error`                                                                 |
| Pre-receipt failures   | `eval_deploy_failed`, `eval_tunnel_failed`, `eval_key_release_unavailable`, `eval_no_result`                                                                                                        |
| Terminal public labels | `valid`, `invalid`, `suspicious`, `error` (and owner override forms where configured)                                                                                                               |

Review and eval history routes use stable cursor pagination (default 10, max 16) and retain cancelled, expired, failed, and superseding attempts.

## Terminal-Bench and the live task cache

Production evaluation resolves Terminal-Bench task trees from a **measured guest path** (conceptually `/opt/agent-challenge/task-cache`). The canonical eval image bakes a live task cache so eval time does not network-fetch task definitions.

* Prepare/select draw from the pinned digest fallback set when residual task-count paths apply
* Incomplete bake surfaces as a guest task definition miss during preflight, **before** key release
* Eval isolation uses Docker-out-of-Docker style trial containers inside the measured guest

## Scoring

* Each selected task contributes a task score
* Aggregate score is typically the average across selected tasks for a completed valid submission
* Task selection is deterministic relative to the agent hash and the eval prepare plan
* Defaults may use winner-take-all among valid submissions when configured; otherwise best score per miner hotkey
* Only effective status `valid` or `overridden_valid` can produce weight entries and leaderboard rows
* Timed-out tasks are terminal, non-passing, score 0, counted once
* On the attested path, weight eligibility requires **verified** attestation acceptance including durable key-grant

`GET /internal/v1/get_weights` is the challenge weight contract. BASE normalizes to UIDs (cross-repo).

## Acceptance checks (eval result)

Before writing an accepted score the challenge verifies, in conjunction:

* TDX quote integrity and acceptable TCB
* Event log replay / compose identity
* Measurement present on the **eval** allowlist
* Score-domain `report_data` binds measurement, agent hash, task ids, scores digest, score nonce and eval\_run\_id
* **Key-grant consistency** for that eval run (no grant, no score)
* Nonces single-use / fresh
* Fresh re-verified review allow at eval admit time

Invalid or rejected results write no accepted score.

## Offline and flag-off

With attestation flags **OFF**, the service may still run offline AST helpers and historical evaluation helpers for local CI. That mode:

* must not be described as production scoring
* does not require miners to spend Phala credits
* keeps operators as challenge service runners, not substitutes for miner TEE self-deploy
