Generated: {report_time}

## Result
BROKEN_STATE_ROUNDTRIP_PROVED

## Broken state induced
- Temporary isolated `HERMES_HOME` was created under `mktemp`.
- `config.yaml` inside that isolated home was set to:
  - `delegation.provider: minimax`
  - `delegation.model: MiniMax-M2.7`
- `MINIMAX_API_KEY` and `MINIMAX_CN_API_KEY` were explicitly removed from the doctor subprocess environment so the readiness path had to fail on missing credentials instead of inheriting the real machine state.

## Before repair — doctor output
```text
{blocked}
```

## Canonical repair path
1. Clear the delegation override so subagents inherit the parent runtime.
2. Re-run `python -m hermes_cli.main doctor`.
3. Confirm `◆ Delegation Readiness` flips from blocked to ready before trusting delegated work.

## After repair — doctor output
```text
{ready}
```

## Proof notes
- The broken state was isolated to a temporary `HERMES_HOME`; the real `~/.hermes/config.yaml` was not modified.
- The ready state after repair was proved by replacing the isolated config with an empty config (`{{}}`), which removes the delegation override entirely.
- Script used: `{relative_script}`

## Honest next move
Run one real delegated task from the live ready environment and append that proof to the canonical packet.
