fix: HFO risk-level breakdown groups by Active Life Threat

CHANGELOG.md

@@ -14,6 +14,10 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 - **PRs need a CHANGELOG entry**—A new check fails a pull request that doesn't change `CHANGELOG.md`. Changes nobody would notice, such as a typo fix or a refactor with no import or behavior change, take the `no-changelog` label instead. `/create-pr` now drafts the entry, or adds the label, before opening the PR.
 - **Guards against changed scores**—Unit tests pin results with fixed inputs, so a code change can't move scores unnoticed. One per stage: golden persona prompts and a replay of recorded user and chatbot replies (generate), scripted answers walking the SI rubric (judge), and golden `scores.json` files (score); plus a replay of the whole recorded pipeline. None calls a model. See [docs/safe-changes.md](docs/safe-changes.md).
 
+### Fixed
+
+- **HFO runs get a risk-level breakdown instead of a traceback**—Scoring grouped conversations by SI's `Short Current Suicide Risk Level` persona column for every target, so on HFO, whose personas file doesn't have it, `vera pipeline`, `vera score`, and `vera pool` printed a `KeyError` traceback and skipped `scores_by_risk.json`. Each target's `manifest.json` now says how to break its scores down, in an optional `risk_levels` section with the persona column and its levels in order ([docs/targets.md](docs/targets.md)): SI groups by `Short Current Suicide Risk Level` (`None`, `Low`, `High`, `Immediate`), HFO by `Active Life Threat` (`N/A: No harm`, `Absent`, `Present`), which matches the HFO rubric's danger tiers. A personas file with no manifest beside it that lists it and has `risk_levels`, such as a custom file passed to `--personas`, skips the breakdown with a one-line note. `score.utils.RISK_LEVEL_ORDER` and `RISK_LEVEL_COLUMN` are gone; `load_risk_levels(personas_path)` returns the column and order. SI scores are unchanged.
+
 ### Documentation and development workflow
 
 - **Release 2.1 plan**—[`docs/roadmap.md`](docs/roadmap.md#release-21-plan) lists the steps for 2.1 in dependency order with their PRs: safety net, data contracts, job loop, terminal output, then removing `legacy/`, with the judge-flow rewrite in parallel. They accumulate on a `release/2.1` branch that merges into `main` once, at the 2.1.0 tag, so `main` stays releasable; CI now also runs for `release/2.1`.
