Versioning¶

✨ Put[E] is an explicit creation marker, so a return annotation can spell out all three verbs — -> list[Put[Payslip] | Patch[Employee] | Delete[Timesheet]] — instead of leaving creation implicit in a bare type. Pure sugar: returning a bare Entity/Config still creates it (#65).

✨ Store.history(obj) returns every write a run made to an object — which step, which action, which fields — recorded from the single place all writes go through (#56).
✨ Workflow.run(store, atomic=True) rolls the store back to its initial state if any step raises, making the whole run all-or-nothing instead of just each step (#35).
✨ check() reports a type produced further down the list as an ordering problem, naming the step to move and its position, instead of reporting the type as simply absent (#54).
✨ An exception raised by a module, or while applying its output, is re-raised unchanged with a note naming the step, its position and the state of the store (#55).
🔄 Breaking: Workflow.run only fills last_run when passed record=True. Recording costs one deep copy of the store per step and was previously paid by every run, including the ones that never replay (#53).
🐛 Pre-commit's ruff-format/ruff-check hooks matched files: ^morph/, a leftover from before the package was renamed to morphly; they ran on nothing.

First release.

✨ Initial API: Entity, Config, Store, @module/Module, Step, Workflow, Patch, Delete, view.
✨ Workflow.to_mermaid() renders the dataflow as a Mermaid flowchart (#32).
✨ on_step receives the operations a step just wrote, not just its name (#30).
✨ Store.drop() and Store.patch() can target by (type, name), not only by instance (#31).
✨ Workflow.run(reuse=...) skips steps whose inputs are unchanged since a previous run (#33).
🐛 check() now validates the Config a module reads, not only the entities (#28).
🐛 A step that Patches a target it already Deleted in the same step now raises a clear error instead of an opaque KeyError (#29).
🔄 Breaking: renamed the package morph → morphly and Pipeline → Workflow, ahead of the first PyPI publish.
🔄 Lowered requires-python to 3.12 (#34).
🧹 Split the single module into entity.py / module.py / operations.py / store.py / workflow.py, one per concept.
📚 Added the documentation site (zensical, deployed to GitHub Pages), CONTRIBUTING/SECURITY/code of conduct, and a py.typed marker (#4, #5, #7).
