factorforge-cds 3.2.4

FactorForge - open-source CDS design and pre-synthesis sequence review engine by Eijex.

FactorForge

Open-source constraint-based CDS design and pre-synthesis sequence review engine for plant CDS workflows, with primary support for Nicotiana benthamiana (Tobacco BY-2: experimental).

FactorForge performs profile-guided CDS design with CAI/GC metrics, PolyA-signal screening, and Golden Gate/MoClo-aware checks. It is positioned as a pre-synthesis review harness: it helps teams generate reproducible CDS candidates, inspect assembly-relevant sequence constraints, and package design metadata before downstream synthesis, cloning, or experimental review. Primary support: N. benthamiana (agroinfiltration). Experimental host context: Tobacco BY-2 (--host by2).

Access Options

Method	Description	Link
Web App	No installation, demo & light use	factorforge.eijex.com
CLI / Python	Local use, batch processing, data privacy	pip install factorforge-cds
Docker	Full web interface locally	docker pull ghcr.io/eijex/factorforge-cds:latest

Repository Structure

The supported production engine is the deterministic profile engine under:

src/factorforge/engines/profile/

Historical implementation tracks are preserved under archive/ for provenance and are not imported by the installed package or exposed as supported engines.

⚠️ Validation Status

FactorForge outputs are in-silico only and have not been experimentally validated in wet-lab conditions. These checks support reviewability and reproducibility; they do not guarantee expression, yield, synthesis acceptance, folding, glycosylation, regulatory approval, or downstream biological performance. See Validation and VALIDATION.md.
