| # HolyCyber — Layer: `secure_coding` | |
| A focused dataset for the `secure_coding` domain of the HolyCyber corpus, built on its own from that domain's authoritative sources only. | |
| ## Overview | |
| - **Rows:** 2,659 | |
| - **Groups (leakage units):** 1,001 | |
| - **Entities in the domain:** 1,018 | |
| - **Splits:** test=266, train=2,144, val=249 | |
| - **Task types:** 8 | **Subdomains:** 6 | |
| - **Row size (tiktoken cl100k, user+assistant):** min 2,088 / median 2,331 / mean 2,359 / p90 2,533 / max 5,369 tokens | |
| - **Entity's own material:** median 14% of an answer's tokens; 2,046 rows are below 25% (the balance is the labelled reference appendix) | |
| - **Total tokens:** 6,272,640 | **Rows below the 2,000-token floor:** 0 | |
| - **Canary:** every row carries the decontamination canary | |
| ## Record format | |
| One JSON object per line; `messages` is a three-turn chat (system / user / assistant). | |
| ```json | |
| {"id": "6d408e38f3cb8dff", "row_key": "<domain>:<group_key>:<task_type>:<subdomain>:<part>", | |
| "domain": "secure_coding", "subdomain": "...", | |
| "task_type": "...", "difficulty": "intermediate", "group_key": "...", | |
| "source": "...", "license": "...", "split": "train", "canary": "...", | |
| "tokens": {"user": 180, "assistant": 2350, "total": 2530}, | |
| "core_share": 0.41, "appendix": true, | |
| "references": [{"title": "...", "url": "..."}], | |
| "messages": [{"role": "system", "content": "..."}, | |
| {"role": "user", "content": "..."}, | |
| {"role": "assistant", "content": "## ...\n..."}]} | |
| ``` | |
| | Field | Meaning | | |
| |---|---| | |
| | `id` | content hash of user+assistant, stable across rebuilds of the same row | | |
| | `row_key` | stable identity across rebuilds (`domain:group:task:subdomain:part`) | | |
| | `domain` / `subdomain` | this layer, and the slice of it the row covers | | |
| | `task_type` | the question shape (detection, mitigation, mapping, ...) | | |
| | `difficulty` | derived from the task shape, not guessed | | |
| | `group_key` | the source entity; the unit of the train/val/test split | | |
| | `source` / `license` | the authoritative source, and its licence | | |
| | `tokens` | measured `cl100k_base` counts for user, assistant and total | | |
| | `core_share` | share of the answer that is the entity's own material (1 - appendix) | | |
| | `appendix` | whether the row carries a `## Reference:` appendix | | |
| | `references` | resolvable links for the entities cited in the answer | | |
| | `canary` | decontamination marker | | |
| ## What a row contains | |

| ## How this layer is built | |
| 1. **Base cells** — the rows the source parsers emit for this domain (one per entity x task type x subdomain). | |
| 2. **Task shapes** — the same entity asked a different defensive question (detection, mitigation, framework mapping, response), built only from other sections of that entity's own record. No new facts are introduced. | |
| 3. **Reference pack** — a row still under the token floor is padded with compact descriptions of other entities *of this domain*, taken from this domain's own source text; the window rotates per row. | |
| Every row therefore comes from this domain's sources only, clears the 2,000-token floor, and no two rows are the same. | |
| ## Task types | |

| | Subdomain | Rows | | |
| |---|---| | |
| | vulnerable_vs_fixed | 756 | | |
| | root_cause | 581 | | |
| | remediation_principle | 548 | | |
| | residual_risk | 465 | | |

| ## Sources | |
| | Source | Rows | | |
| |---|---| | |
| | cwe | 2,548 | | |
| | arxiv-corpus | 98 | | |
| | owasp-cheatsheet | 13 | | |
| ## Quality controls | |
| - **Exact duplicates removed:** 0 | |
| - **Near-duplicates removed:** 0 (MinHash-LSH, Jaccard >= 0.90, same task type only) | |
| - **Quality gate:** 225 rejected ({'unbalanced_code_fence': 225}) | |
| - **Contaminated rows removed:** 0 ({}) | |
| - **Split integrity:** group-level by `group_key`; no group crosses a split | |
| ## Intended use | |
| Supervised fine-tuning / evaluation of a defensive cybersecurity assistant specialised in this domain. All rows are defensive, detection or analysis oriented; none contains functional exploit code or weaponised prompts. | |
| ```python | |
| from datasets import load_dataset | |
| ds = load_dataset("json", data_files=dict(train="secure_coding/train.jsonl", validation="secure_coding/val.jsonl", test="secure_coding/test.jsonl")) | |
| # rows whose answer is mostly the entity itself, not the appendix | |
| core = ds["train"].filter(lambda r: r["core_share"] >= 0.5) | |
| ``` | |
| ## Limitations | |
| - 2,046 of 2,659 rows are more than 75% labelled reference appendix: this domain's own records are shorter than the 2,000-token floor, so the row is completed with other entities' records. Mask the appendix when fine-tuning if you only want the core answer. | |
| - Paragraph-level reuse is measured in `research/AUDIT_REPORT.md`; rows are unique but their appendix material is shared. |
