Roadmap

Features deliberately deferred from v0.3, to be prioritized based on real-world demand.

Feature	Description
DAG mode	Explicit step dependencies (depends: [stepA, stepB]) instead of linear sequence. Sequence + parallel covers 95% of cases today, but complex graphs with many cross-dependencies become hard to express linearly.
Durability / resume	Workflow survives a runtime crash and resumes from where it stopped. Requires storage and state serialization decisions — a runtime feature, not a spec feature.
Matrix / fan-out	Combinatorial execution (e.g., run tests across 3 Node versions × 2 operating systems). Useful for CI, outside the core use case.
Secrets management	Dedicated credential store with rotation and auditing. env is sufficient for now; a secret store is an infrastructure decision.
Workflow versioning	Run v1 and v2 simultaneously with gradual migration. Relevant when multiple executions are in production.
Caching between runs	Reuse outputs from idempotent steps across executions. Performance optimization, not new functionality.
Backpressure / gates	Gates that reject incomplete work and force re-execution.
Persistent mode	Workflow running as a daemon, reacting to events continuously instead of a single execution.
Concurrency control	Limit parallel executions of the same workflow or specific steps.
YAML anchors / fragments	Reuse of configuration blocks within the same file via YAML anchors.
