+
+## [1.2.0] - 2026-07-12
+
+### Added
+- Expanded to **470** secure/vulnerable code pairs (**+260** over v1.1.0) and **30 LLM security trajectories**.
+- **Deep language packs**: 20 Python deep records (SCP-000211–230), 10 Java deep records (SCP-000231–240).
+- **Cross-language pack**: 30 records across Ruby/C/C++/Scala/Go/JS/TS/C#/PHP/Rust/Kotlin/Swift/YAML (SCP-000241–270).
+- **Domain packs**: healthcare/FHIR (PHI, IDOR on Patient/lab), fintech/banking (race conditions, idempotency, payment keys, ledger SQLi, prototype pollution), GraphQL (introspection, field-level authz, depth-bomb, batching CSRF), gRPC (auth interceptor, metadata validation), and an SSRF collection (Go/Python/Ruby/C# proxies).
+- **LLM security trajectories** (`trajectories.jsonl`, 30 records, `SCP-TRAJ-001`–`030`): prompt injection (direct/indirect/RAG/multimodal/voice/code-comment/chained), RAG poisoning (KB/financial/medical/license/CVE), tool-use abuse (file write, email, webhook, notify, SQL, purchase, loop exhaustion), jailbreaks (DAN/role-play/obfuscation/hypothetical/translation/authority/base64), and data exfiltration (pixel beacons, markdown images, prompt encoding, log smuggling).
+- **CITATION.cff** for academic citation.
+- **Leaderboard / benchmark** guidance in README (4 suggested eval tasks over the `benchmark` split + `trajectories.jsonl`).
+- `trajectories.py` source module; `data_ext5`–`data_ext10` source modules.
+
+### Changed
+- `build.py` now also writes `trajectories.jsonl` and a richer `manifest.json` (total_code_records, total_trajectories).
+- Splits (code): train (311) / validation (56) / test (56) / benchmark (47).
+- README expanded with trajectory schema, leaderboard section, and full v1.2.0 statistics.
+
+### Validation (v1.2.0)
+- **PASS**: 470 code records, 0 errors. (250 non-fatal warnings from framework-context snippets under best-effort compile checks — same class as v1.1.0.)
+
+## [1.1.0] - 2026-07-12
+
+### Added
+- Expanded to **210** secure/vulnerable code pairs (**+160** over v1.0.0).
+- **5 new languages**: Ruby, C, C++, Scala, and YAML (Kubernetes manifests) — **15 languages total**.
+- **New frameworks**: Rails, Qt, Play Framework, gRPC, GraphQL, and Kubernetes.
+- **New paradigms**: GraphQL field-level authorization & depth-bomb DoS; gRPC auth metadata & unauthenticated delete; Kubernetes Pod security contexts & RBAC; IoT/firmware (C/embedded) and mobile (Android/iOS) deep-link abuse.
+- **New domains**: fintech (payment, transfer, 2FA), healthcare/FHIR, Kubernetes, IoT, serverless.
+- **CVSS 3.1 vectors** injected for every record (derived from severity + class flags; overrides allowed per record).
+- **Benchmark split** (21 records) added alongside train/validation/test for leaderboard-style evaluation.
+- Per-record `cvss_vector` field added to the schema.
+- Best-effort **compile/syntax checks** per language (Python `ast`, Java `javac`, Go `go vet`, Rust `rustc`, C/C++ `gcc`/`g++ -fsyntax-only`, Ruby `ruby -c`, JS `node --check`); framework-dependent snippets fall back to a brace/paren heuristic.
+
+### Changed
+- `build.py` aggregates `data.py` + `data_ext*.py` and writes four splits with a fixed seed.
+- `validate.py` now checks CVSS vector format, difficulty enum, new languages, and runs compile checks (warnings, non-fatal).
+- `statistics.py` includes the benchmark split and adds difficulty/domain distributions.
+
+### Validation (v1.1.0)
+- **PASS**: 210 records, 0 errors. Compile/syntax checks run best-effort; framework-context snippets report non-fatal warnings only.
+
+## [1.0.0] - 2026-07-12
+
+### Added
+- Initial curated release of **50** secure/vulnerable code pairs.
+- Coverage across **10 languages**: Python, Java, JavaScript, TypeScript, Go, PHP, C#, Kotlin, Swift, Rust.
+- Coverage across **13 frameworks**: Flask, Django, FastAPI, Spring Boot, Express, NestJS, Next.js, Laravel, ASP.NET Core, Gin, Android, iOS, Actix.
+- **29+ vulnerability classes** mapped to OWASP Top 10 (2021), OWASP API Top 10 (2023), OWASP LLM Top 10 (2025), MITRE CWE, and MITRE ATT&CK.
+- Per-record fields: id, language, framework, title, description, owasp*, cwe, mitre_attack, severity, difficulty, vulnerable_code, secure_code, patch, root_cause, attack, impact, fix, guideline, tags, metadata.
+- Train / validation / test splits (34 / 8 / 8) with deterministic seed.
+- Automated validation script producing `validation/validation_report.md` (v1.0.0: PASS).
+- Statistics CSVs and ASCII charts under `statistics/`.
+- Dataset card (`README.md`), `LICENSE`, `CONTRIBUTING.md`, `SECURITY.md`, `CODE_OF_CONDUCT.md`.
+
+### Validation
+- JSON validity, duplicate-id check, required-field presence, OWASP/CWE format consistency, Python `ast.parse` compilation, and label consistency all pass.
+
+## [Unreleased]
+
+### Planned (v1.2.0)
+- Reach 500+ records with single-language deep packs (e.g. 50 Python, 50 Java).
+- Add CI-style automated tests that compile/run each example against a benign harness.
+- Add multi-turn agent/LLM security trajectories (tool-use, RAG retrieval poisoning).
+- Add executable test fixtures (assert secure passes, vulnerable fails) per record.
+- Add dataset citations and a leaderboard README.

+# Contributing to SecureCodePairs
+
+Thanks for helping improve the dataset! We welcome high-quality, original secure/vulnerable code pairs.
+
+## How to add a record
+
+1. Fork the repository and create a branch: `git checkout -b add-SCP-00XXXX`.
+2. Open `scripts/data.py` and append a new dict to the `RECORDS` list.
+3. Follow the schema in `README.md` exactly. Required fields must be non-empty.
+   - `tags` must be a **list of strings**.
+   - `metadata` must be a **dict** with at least `domain`, `input_source`, `auth_required`.
+   - `owasp_api` / `owasp_llm` may be empty strings when not applicable.
+4. Every example must include BOTH a `vulnerable_code` and a correct `secure_code` plus a `patch` diff.
+5. Never submit template-renamed duplicates or low-quality synthetic noise. Code must look like something a real developer wrote.
+6. Run the checks locally:
+   ```bash
+   python3 scripts/build.py
+   python3 scripts/validate.py
+   python3 scripts/statistics.py
+   ```
+   The validator must finish with **PASS** (0 errors).
+7. Open a pull request describing the vulnerability class and language/framework added.
+
+## Quality bar
+
+- Realistic, production-like naming and architecture.
+- Accurate OWASP / CWE / ATT&CK mappings.
+- The `secure_code` must actually fix the `root_cause`.
+- Defensive context only: no context-free weaponized exploits.
+
+## Review
+
+Maintainers will verify mappings, run the validation suite, and check for duplicates before merging.

+
+## Leaderboard / Benchmark
+
+The `benchmark` split (47 records) is a curated, balanced subset for leaderboard-style evaluation of secure-code
+generation and vulnerability-detection models. Suggested tasks:
+
+1. **Vulnerability classification** — given `vulnerable_code`, predict `cwe` / `owasp` / `severity`.
+2. **Secure-code synthesis** — given `vulnerable_code` + `description`, generate `secure_code` (scored vs. reference patch).
+3. **Patch generation** — produce a unified `patch` from vulnerable→secure.
+4. **Agent safety (trajectories)** — given a `trajectories/trajectories.jsonl` turn sequence, flag the `is_attack` turn and predict `mitigation`.
+
+Report metrics (precision/recall/F1 for classification; BLEU/CodeBLEU + functional correctness for synthesis) with the
+`benchmark` split only, and cite this dataset.
+
+---
+
+## Validation
+
+Automated checks live in [`scripts/validate.py`](./scripts/validate.py) and a report in
+[`validation/validation_report.md`](./validation/validation_report.md). The v1.2.0 run is **PASS**:
+
+- JSON validity per line ✅
+- No duplicate record ids ✅
+- All required fields present and non-empty (tags/metadata typed) ✅
+- OWASP / OWASP-API / OWASP-LLM / CWE format consistency ✅
+- Python examples compile (`ast.parse`) ✅
+- Label consistency (severity ∈ {Low,Medium,High,Critical}) ✅
+
+Reproduce:
+
+```bash
+python3 scripts/build.py
+python3 scripts/validate.py
+python3 scripts/statistics.py
+```
+
+---
+
+## Reproducibility
+
+All examples are hand-authored (no template-renamed duplicates). Source records live in `scripts/data.py` and
+`scripts/data_ext*.py`; trajectories in `scripts/trajectories.py`. The build uses a fixed seed (`42`) for deterministic
+train/validation/test splits. See `dataset/manifest.json`.
+
+---
+
+## Limitations
+
+- v1.2.0 covers 470 curated code examples + 30 trajectories; not exhaustive across every CWE/language permutation.
+- Compilation/formatting is verified for Python; other languages are reviewed by hand (no language compilers bundled, except best-effort heuristics).
+- Examples are illustrative and may omit full project context (imports, config) needed to run standalone.
+- Severity is CVSS-style guidance from the author, not a formally scored CVSS vector.
+- Trajectories are synthetic agent scenarios for safety research, not transcripts of real systems.
+
+## Ethical Considerations & Responsible AI
+
+The dataset teaches defense. Vulnerable code is provided only with explicit remediation and never as a how-to for attack.
+It must not be used to compromise systems without authorization. Models trained on it should be evaluated for safe,
+remediation-aware generation. Maintainers will review contributions to avoid adding weaponized, context-free exploits.

+
+If you discover that any **secure** example in this dataset is actually insecure, or that a mapping is wrong,
+please report it privately rather than opening a public issue.
+
+- Email: security contact via the Hugging Face dataset discussion/Security tab.
+- Include: the record `id`, the issue, and a suggested correction.

+
+## Scope note
+
+This dataset intentionally contains **vulnerable** code for educational purposes. Reports should focus on:
+1. Incorrect/weak "secure" remediations.
+2. Wrong OWASP/CWE/ATT&CK mappings.
+3. Examples that could be misinterpreted as attacks without remediation context.
+
+Do **not** use this dataset to attack systems you are not authorized to test.
