+## [Unreleased — Pre-synthesis Quality Sprint] — 2026-06
+
+**Status:** Pipeline frozen for synthesis batch ordering. All changes below were quality
+improvements made before committing the ~$10k wet-lab synthesis budget.
+
+### Added
+
+- `docs/WET_LAB_HANDOFF.md` — score interpretation table, synthesis decision thresholds,
+  per-flag QC remediation guide, MIC/hemolysis assay protocols, troubleshooting section
+- `configs/phase3.yaml` now validated by CI at the same level as `pipeline.yaml`
+  (selection keys, weights, filters all pinned in test_config.py)
+- `test_compute_features_supplies_synthesis_feasibility_keys` — integration contract test
+  ensuring `compute_features()` always returns the three keys accessed without `.get()` by
+  `synthesis_feasibility_score()` (`length`, `longest_repeat_run`, `cysteine_fraction`)
+- `SynthQC.to_dict()` fully covered with 16 tests (key presence, types, value round-trips)
+- `presynth-qc` CLI command now has 4 integration tests (exit code, file creation, flag
+  detection, summary table content)
+- `validate_json_schema()` error paths covered: ValidationError, missing required field,
+  wrong type, FileNotFoundError on bad schema path
+- `synthesis_feasibility_score()` missing-key tests document the direct dict-access contract
+- `check_panel()` missing-column error tests for `candidate_id` and `sequence`
+- `make ci` target: runs `lint` then `test` in one command
+
+### Fixed
+
+- `ensemble_score()` no longer crashes with KeyError for missing weight keys; emits
+  `UserWarning` listing missing names and defaults to 0.0 (PR #24)
+- Eligibility filter: `>= min_novelty` boundary confirmed and tested (PR #24)
+- `load_candidates_csv()` validates CSV header before iterating rows; raises descriptive
+  `ValueError` instead of bare `KeyError` (PR #25)
+- Disagreement gate (`max_disagreement`) added to eligibility filter in `pipeline.py`
+  (PR #25); `pipeline.yaml: 0.40`, `phase3.yaml: 0.30`
+- `WET_LAB_HANDOFF.md` μH boundary table corrected to `> 0.55` (matching code) vs
+  closed interval; phase3 disagreement threshold (0.30) explicitly named in troubleshooting
+
+### Tests
+
+- **814 tests passing** (up from initial ~400 at start of sprint)
+- All ruff lint checks passing
+
+---
+
+## [v0.4.0] — Boman Scorer + Safety Stratification
+
+- Added Boman index scorer (`scoring/boman.py`)
+- Added hydrophobic moment (μH) to physchem features
+- Added μH-based hemolysis stratification to pre-synthesis QC report
+- Added model disagreement score (`|activity_likeness − boman_activity|`)
+- 89 lab-ready AMP nominees with evidence certificates
+
+## [v0.3.0] — Pre-Synthesis QC + Pilot Panel
+
+- `qc/presynth_check.py`: full SPPS QC report (MW, pI, charge, trypsin sites, deamidation,
+  aggregation risk, UV chromophore, formulation notes)
+- `pilot-panel` CLI command: 20-candidate first-synthesis-wave selector
+- Bootstrap AUROC confidence intervals for benchmark results
+- Gold-standard calibration check against known-active AMP panel
+
+## [v0.2.0] — Confidence Gaps + Benchmarking
+
+- Benchmark leakage detection (`bench leakage`)
+- Run manifest with input file hashes and config snapshot
+- Standard AUROC benchmark gate (AUROC = 0.8037 on held-out positives)
+- Evidence certificates (JSON-schema-validated) for each nominated candidate
+
+## [v0.1.0] — Initial Pipeline
+
+- Template mutation generator
+- Physchem feature extraction (length, charge, hydrophobicity, aromatic fraction, etc.)
+- Activity likeness, safety, synthesis feasibility, novelty scoring
+- Ensemble scoring with configurable weights
+- JSONL output with per-candidate `selected` field
+- `pipeline.yaml` and `phase3.yaml` configs
