regent 0.7.0

Optimistic, message-driven state engine: a journal of sealed facts folded into keyed stores and units, with guards, correlation, and merge edges. Pure Dart.

0.7.0

• replay(rows, order) / replayStore: fold a message order on a pure ledger to a state snapshot — order-(in)dependence as a law via equals/isNot.
• @pure marker on the fold-family contracts (Store/Unit.reduce, Guard.judge).

0.6.0

• Ledger.of(rows): the declared ledger — closed citizen list from the regent enum; memoryOf(row); positional on<M>(before: row) reads the feed at any declared row.

0.5.0

• Row-grain store feed: rowChanges() + inserted/updated/upserted/deleted stream verbs.

0.4.0

• Regent citizen base; positional Guard/Veto rows; segmented queue; keyed verdicts.

0.3.0

• Observation is async (post-cut): store streams and ledger.on deliver after the traversal; dispatch during a fold/guard asserts.
• mergeStore: keyed-store merge sources; store sources join the collection union.
• Source/CommonSource removed — provenance is said by types and stores.
• Event-stream verbs: transitions, entering, on<M> on store event streams.

0.2.0

• Verdict: the write correlation twin — prediction + resolver types, settled by state comparison.
• Optimistic overlays and rollback on unit stores.
• Stability.reverted / .amended and the tampered flag.
• awaits/verdict declared as super constructor fields; Store.initial is named.

0.1.1

• README refreshed for the regent identity.

0.1.0

• Initial release: message bus with a journal/admitted split, typed guards and vetoes.
• Store/Unit pure reduce specs; StoreMemory/UnitMemory live stores with optimistic overlays.
• Awaits correlation twins: key-correlated request status + the surface scope-entry ask.
• Store event streams: one post-fold event per delivered family message.
• Projection merge edges: a unit's state answers a keyed surface's reads at its own id.
• @stores grammar (StoreNode) for canon's generator.
