Upgraded `subworkflows/local/variant_calling/main.nf` with dynamic caller selection via `--snv_caller` (`bcftools`, `deepvariant`, `clair3`). +- **Epigenomics Specialization**: + - Added **`modules/nf-core/pbcpgtools`** for native PacBio HiFi CpG aggregation (`aligned_bam_to_cpg_scores`). + - Implemented platform-split epigenomics in `subworkflows/local/methylation/main.nf`: native `pbcpgtools` for PacBio HiFi vs `modkit pileup` for Oxford Nanopore. + - Added **`CHECK_MOD_TAGS`** validation process ensuring SAM auxiliary kinetic tags (`MM`/`ML`) are verified prior to pileup. +- **Joint Multi-Variant Co-Phasing**: + - Upgraded **`modules/nf-core/hiphase`** to jointly co-phase small variants (SNVs/indels), structural variants (`Sniffles2`), and tandem repeat expansions (`TRGT`) into unified phase sets (`PS`). + - Added **`modules/nf-core/whatshap/stats`** for phase block metric calculation and N50 reporting. +- **Empirical GIAB HG002 Truth-Set Benchmarking**: + - Added **`modules/nf-core/happy`** for small variant (SNV/Indel) concordance evaluation against NIST GIAB truth sets. + - Added **`modules/nf-core/truvari`** for structural variant ($\ge 50$ bp) precision and recall benchmarking against GIAB Tier 1 benchmarks. + - Created **`subworkflows/local/benchmarking/main.nf`** integrated into all pipeline entrypoints. + - Added dedicated benchmark profile **`-profile test_giab`** (`conf/tests/test_giab.config`) and mock truth assets in `tests/data/giab/`. + - Authored comprehensive validation guide and baseline expectations in **`docs/validation.md`**. +- **Transparent MultiQC Analytical Stage Execution Matrix**: + - Implemented **`modules/local/execution_status_matrix/main.nf`** generating `pipeline_execution_status_mqc.tsv`. + - Wired into MultiQC (`assets/multiqc_config.yml`) to transparently report the status (`COMPLETED`, `SKIPPED (Pre-aligned Input)`, `SKIPPED (Parameter-Disabled)`, `FAILED`) across all 12 pipeline analytical stages. +- **Automated Security, Secret & PHI Auditing**: + - Added **`bin/security_audit.py`** and root-level runner **`security_check.sh`** for zero-dependency scanning of credentials, tokens, cloud keys, private keys, local user paths, and PHI. + - Added **`.pre-commit-config.yaml`** for local git pre-commit hook integration. + - Integrated fail-fast security gate into **`.github/workflows/ci.yml`** to block pull requests and commits containing sensitive data. +- **Automated Negative Test Regression Suite**: + - Added **`tests/run_negative_tests.sh`** and **`tests/pipeline/negative_tests.nf.test`** testing fail-fast exit codes (exit 1) on missing references, platform mismatches, and invalid samplesheets. +- **On-Demand Auto-Indexing**: + - Added **`modules/nf-core/samtools/index`** and **`modules/nf-core/samtools/faidx`** for automatic indexing of pre-aligned BAMs and reference FASTA files. + +### Changed +- **Regulatory Scope & Intended-Use Reframing**: + - Re-scoped `README.md` and `docs/validation.md` strictly to **Research Use Only (RUO) / Clinical Evaluation Platform**, clarifying that clinical diagnostic deployment requires site-specific analytical validation (e.g. CAP/CLIA or ISO 15189). + - Documented physical chemistry boundaries (Oxford Nanopore simplex homopolymer indel resolution, 5mC vs 5hmC depth requirements, PacBio HiFi coverage and kinetic tags, phase block continuity limits). +- **Native Streaming Tag Preservation**: + - Deprecated in-memory dictionary-based `transfer_mod_tags.py`, replacing it with native streaming alignment (`minimap2 -ax map-ont -y` and `pbmm2`), guaranteeing coordinate-accurate reverse-strand `MM`/`ML` tag propagation with minimal memory overhead. +- **Full-Chain PHI De-Identification & Forensic Audit Manifest**: + - Upgraded `subworkflows/local/governance`: Dedicated `SANITIZE_BAM` and `SANITIZE_VCF` generating deterministic `anon_id`, stripping patient identifiers, hospital run barcodes, and tool command lines. + - Re-routed downstream `VISUALIZATION` (JBrowse 2, Methylartist, Dashboard) and `REPORTING` across all workflows to consume exclusively sanitized artifacts. + - Expanded `manifest.json` into a cryptographic full-chain provenance record binding raw input SHAs, reference FASTA checksums, workflow commit ID, container digests, execution parameters, and output checksums. + - Pinned container image digests in `conf/version_lock.config`. + +### Fixed +- **Groovy Boolean Channel Evaluation Bug**: + - Replaced Groovy boolean channel checks (`if (channel)`) with idiomatic Nextflow DSL2 `.branch { ... }` operators in `nanopore.nf`, `pacbio.nf`, and `longvarmeth.nf`. + - Fixed dropped FASTQ inputs and prevented pre-aligned BAMs from incorrectly entering `MERGE_BAMS`. +- **Silent Parameter Bypass on Missing Reference**: + - Updated `lib/Utils.groovy` with fatal fail-fast validation: immediately terminates execution (`exit 1`) with an explicit error banner when `--run_type reference_based` lacks a valid `--ref_nuc`. +- **Platform & Chemistry Cross-Validation**: + - Added strict platform validation in `lib/Utils.groovy`, instantly rejecting mismatched platform inputs (e.g. PacBio BAMs passed to `--platform ont`). + - Added duplicate sample ID detection and required column header validation. +- **Channel Closure Arity**: + - Resolved variable tuple arity exceptions in multi-channel joins within `phasing/main.nf` and `governance/main.nf`. + +### Security +- Sanitized remaining host-specific filesystem paths (`/data/Jyotirmoy/...`) from `conf/fraka.config`, `conf/human.config`, `conf/eukaryote.config`, and template `samplesheet.csv`. +- Hardened `.gitignore` to strictly ignore private keys (`*.key`, `*.pem`, `*.p12`, `*.pfx`, `id_rsa*`, `id_ed25519*`), environment files (`.env*`), and sensitive credentials. +- Added automated fail-fast security scanning in CI (`.github/workflows/ci.yml`). + +--- + ## [0.3.0] -
