# ESOL Solubility Row Count Mini Task

## Summary

Use the fixed ESOL CSV snapshot from the Delaney solubility dataset to answer a small deterministic data question. The Solver must report how many rows have measured log solubility below `-5` and the SMILES strings for the three rows with the lowest measured values.

## Challenge details

The authoritative input is the fixed `delaney-processed.csv` snapshot listed below. Use the column `measured log solubility in mols per litre` as a numeric value and the `smiles` column as the SMILES string. Rows are identified by zero-based row index after parsing the header. The three lowest rows are selected by ascending measured log solubility, with ties broken by lower row index.

## What you need to submit (Deliverables)

Each required deliverable must be included as a plain file in the Submission.

| Deliverable | Required or optional | Required content | Format or access requirements | Purpose or related criterion |
|---|---|---|---|---|
| `answer.json` | required | `dataset_sha256`, `row_count_below_minus_5`, and `lowest_three`, where `lowest_three` is an array of objects with `row_index`, `measured_log_solubility`, and `smiles` | JSON | Machine-readable answer |
| `report.md` | required | Brief explanation of parsing, numeric comparison, tie handling, and the final answer | Markdown | Human-readable provenance |

## Inputs, Materials and References

| File or reference | Purpose | Required input or background | Link or access instructions | Version or snapshot, if relevant |
|---|---|---|---|---|
| `delaney-processed.csv` | Authoritative ESOL dataset for this task | Required input | Download from `https://raw.githubusercontent.com/deepchem/deepchem/master/datasets/delaney-processed.csv` | SHA-256 `8c06a76f0c6487d29ab0f903e6a7a7139f189ab3c1178f159c8be8964602f189`; 1128 data rows |

The authoritative input is the byte sequence matching the specified SHA-256. Bytes with a different SHA-256 are not the fixed dataset for this bounty.

## Acceptance Criteria

A Submission is valid only if all required deliverables are present and the submitted `answer.json` is consistent with the fixed CSV snapshot and the rules in this page. The count must include every row whose measured log solubility is strictly less than `-5`. The `lowest_three` list must contain exactly the three rows with the lowest measured values, ordered from lowest to highest, with ties broken by lower row index.

## Scoring

This is an exact-answer bounty. A valid answer has no numeric tolerance except ordinary JSON number representation of the source decimal values.

## How is the winner selected?

A valid Submission wins. If multiple Submissions are valid, the winner is the Submission whose lowercase Solver address sorts first in ascending order. If no Submission is valid, the outcome is `no_valid_submission`.

## Disqualification Conditions

A Submission is ineligible if a required deliverable is missing after the Submission is successfully retrieved and opened, if `answer.json` is malformed or lacks required fields, if the reported count or lowest-three rows are inconsistent with the fixed input, or if the Submission uses a different dataset or ranking rule.

## Out Of Scope

This bounty does not ask for model training, new measurements, dataset curation, or any scientific claim beyond the deterministic answer from the fixed CSV.
