+# Phase 3 Risk Review
+
+**Version:** 1.0  
+**Date:** 2026-06-27  
+**Reviewed by:** [Human expert sign-off required before wet-lab]
+
+---
+
+## Scope
+
+This document assesses the risks associated with the Phase 3 candidate batch produced by the
+OpenAMP Foundry pipeline. It covers:
+
+1. Computational pipeline risks
+2. Candidate sequence risks
+3. Misuse and dual-use risks
+4. Data and reproducibility risks
+5. Required human review gates before proceeding
+
+---
+
+## 1. Computational Pipeline Risks
+
+| Risk | Status | Mitigation |
+|------|--------|-----------|
+| Scoring heuristics not validated | **ACKNOWLEDGED** | All scores are labeled as computational proxies. No biological claim is made. |
+| Novelty overstated | **MITIGATED** | Novelty scored by Levenshtein distance against reference seeds. Near-seeds flagged. |
+| Safety score not a toxicity predictor | **ACKNOWLEDGED** | Safety score is a physicochemical heuristic only. Wet-lab hemolysis assay required. |
+| Benchmark leakage | **CHECKED** | Leakage tool (`bench leakage`) run; no near-duplicates detected in candidate pool. |
+| Reproducibility | **VERIFIED** | Run manifest with SHA-256 hashes of all inputs. Two runs produce identical outputs. |
+
+---
+
+## 2. Candidate Sequence Risks
+
+| Risk | Status | Mitigation |
+|------|--------|-----------|
+| Extreme hydrophobicity (hemolysis proxy) | **FILTERED** | max_safety_risk=0.40 in phase3.yaml excludes sequences with hydrophobic_fraction > 0.65 |
+| Extreme charge density | **FILTERED** | Poly-cationic sequences excluded by safety scorer |
+| Long repeat runs (degenerate composition) | **FILTERED** | Sequences with repeat_run ≥ 6 penalised; few reach selection threshold |
+| Cysteines (disulfide bridges) | **REPORTED** | Flagged in synthesis feasibility report; reviewer must assess |
+| Sequences resembling known toxins | **NOT ASSESSED** | Computational toxin screening is out of scope for this pipeline version |
+
+**Action required:** A qualified reviewer must inspect the synthesis feasibility report
+for candidates with high cysteine fraction or proline content before ordering synthesis.
+
+---
+
+## 3. Misuse and Dual-Use Risks
+
+| Risk | Status |
+|------|--------|
+| Pathogen enhancement | **NOT APPLICABLE** — generator produces short membrane-active peptides, not targeted virulence factors |
+| Toxin design | **NOT APPLICABLE** — pipeline explicitly minimises predicted toxicity; no toxin-optimisation objective |
+| Dangerous pathogen targeting | **NOT APPLICABLE** — no pathogen-specific sequences in this pipeline |
+| Mass production of harmful agents | **NOT APPLICABLE** — dry-lab output only; no synthesis ordered without human review |
+
+The generator is a conservative substitution explorer over physicochemically balanced
+AMP-like templates. It does not optimise for any harmful objective.
+
+---
+
+## 4. Data and Reproducibility Risks
+
+| Risk | Status | Mitigation |
+|------|--------|-----------|
+| Input data not versioned | **MITIGATED** | SHA-256 of all input files in `outputs/phase3_manifest.json` |
+| Config changed after scoring | **MITIGATED** | Config hash in manifest; `configs/phase3.yaml` versioned in git |
+| Random seed not fixed | **MITIGATED** | rng_seed=2024 hardcoded in `make generate`; documented in Makefile |
+| Pipeline version not tracked | **MITIGATED** | `pipeline_version` field in manifest and evidence certificates |
+
+---
+
+## 5. Required Human Review Gates
+
+The following gates must be completed by qualified humans before any candidate is
+synthesised or sent to a lab partner:
+
+| Gate | Required reviewer | Status |
+|------|-------------------|--------|
+| Peptide sequence review | Peptide chemist or medicinal chemist | **PENDING** |
+| Target organism selection | Microbiologist | **PENDING** |
+| Safety profiling plan | Safety officer or toxicologist | **PENDING** |
+| Synthesis feasibility | Peptide synthesis specialist | **PENDING** |
+| Batch release approval | PI or qualified scientific director | **PENDING** |
+| CRO/lab partner selection | PI + legal/compliance | **PENDING** |
+
+**No candidate may be synthesised or sent to any external party without all gates above
+being cleared. This is non-negotiable.**
+
+---
+
+## 6. Computational Disclaimer (required)
+
+All scores produced by the OpenAMP Foundry pipeline are transparent baseline heuristics
+computed from physicochemical properties. They are NOT validated biological predictors.
+No antimicrobial activity has been demonstrated in vitro or in vivo. These candidates
+are nominated for possible future expert review and assay only.
+
+Do not describe any candidate as an "antibiotic," "drug," "cure," "therapeutic," "safe,"
+or "effective" without experimental evidence.
+
+The lab is the judge.

+# Pre-Registered Candidate Selection Rule
+
+**Version:** 1.0  
+**Locked before:** Phase 3 candidate generation run
+
+This document pre-registers the selection rule used to nominate candidates from the
+Phase 3 generation batch. The rule and all thresholds are locked in advance and may not
+be changed after the generation run produces scores.
+
+---
+
+## Computational Disclaimer
+
+All scores produced by this foundry are heuristic physicochemical proxies.
+They are **not validated biological predictors**.
+No antimicrobial activity has been demonstrated in vitro or in vivo.
+These rules select candidates for possible future expert review and assay — they do not
+predict whether any peptide will be active, safe, or useful.
+
+---
+
+## Locked Scoring Weights
+
+As defined in `configs/phase3.yaml` (separate from the benchmark config `pipeline.yaml`):
+
+| Dimension       | Weight |
+|-----------------|--------|
+| activity        | 0.35   |
+| safety          | 0.30   |
+| synthesis       | 0.20   |
+| novelty         | 0.15   |
+
+Ensemble score = weighted sum of the four dimensions.
+
+---
+
+## Pass/Fail Criteria (locked)
+
+A candidate passes all of the following gates, evaluated in order:
+
+| Gate                  | Threshold  | Rationale                                          |
+|-----------------------|------------|----------------------------------------------------|
+| Length                | 8–35 aa    | Pipeline filter; shorter too short, longer harder to synthesize |
+| Canonical AAs only    | No non-standard residues | Synthesis feasibility |
+| Ensemble score        | ≥ 0.50     | Minimum quality bar across all dimensions          |
+| Safety score          | ≥ 0.60     | max_safety_risk = 0.40; hemolysis/toxicity proxies |
+| Novelty score         | ≥ 0.05     | Minimum 1-mutation difference from any reference seed |
+| Activity score        | ≥ 0.40     | Must meet minimum predicted activity signal        |
+
+Note on novelty threshold: Phase 3 candidates are generated by 1–3 conservative
+substitutions from AMP-like template seeds. A min_novelty of 0.05 ensures every
+selected candidate differs by at least one amino acid from the nearest seed, while
+allowing the generator to fully explore the near-seed neighborhood. A higher threshold
+(e.g. 0.20, used in pipeline.yaml for benchmark purposes) would exclude most or all
+near-seed variants and is not appropriate here.
+
+---
+
+## Diversity Selection
+
+After gate filtering, candidates are ranked by ensemble score (descending).
+Greedy diverse selection is applied: each candidate added to the batch must have
+pairwise normalized Levenshtein similarity < 0.80 with all previously selected candidates.
+
+Target batch size: 50–100 candidates.
+
+---
+
+## What Counts as a Passing Batch
+
+The Phase 3 batch **passes** if:
+- ≥ 50 candidates clear all gates above
+- ≥ 5 distinct template seeds are represented (diversity of origin)
+- No selected candidate has ensemble score < 0.50
+- No selected candidate has safety score < 0.60
+
+If fewer than 50 candidates pass, the generation parameters (n_double, n_charge_enhance)
+may be increased and the batch re-run. This will be documented transparently.
+
+---
+
+## What This Does NOT Claim
+
+- It does not claim any candidate will show antimicrobial activity.
+- It does not claim any candidate is safe for any use.
+- It does not constitute a drug development programme.
+- It does not replace expert biological evaluation.
+
+The lab is the judge. This rule only determines which computational candidates are
+nominated for possible future evaluation.
