lantern_client 0.1.3

Pure Dart client SDK for Lantern, an in-memory graph key-vertex store with TTL-aware vertices and edges.

Changelog

0.1.3

• Resolve the package lock without descending into the Flutter example on the pure-Dart pub.dev OIDC runner. This patch changes release automation only; the SDK API and runtime behavior are unchanged from 0.1.2.

0.1.2

• Bootstrap pub.dev authentication with the official dart-lang/setup-dart GitHub OIDC flow so headless releases cannot fall back to interactive Google OAuth.
• Bound the publish job with a hard timeout. This patch changes release automation only; the SDK API and runtime behavior are unchanged from 0.1.1.

0.1.1

• Accept the Dart offline contract and set an official, opt-in lantern_client_offline package as the product direction while keeping the online lantern_client free of implicit persistence and platform storage dependencies.
• Specify a single-item durable mutation model, stable logical-call grouping, per-key ordering, explicit dead-letter/ambiguous controls, and independently implementable codec, package, integration, and server follow-ups.

0.1.0

• Scaffold the pure-Dart lantern_client package.
• Add reproducible Connect-Dart and Protobuf code generation.
• Add immutable public Vertex, Edge, input, reference, and batch result models while keeping generated Protobuf types internal.
• Add exact sealed VertexValue variants for every oneof kind, including explicit nil versus unset, full uint64 range, and defensive byte ownership.
• Add strict permanent/relative/absolute expiration contracts and an injected clock for once-per-call relative TTL calculation.
• Add singular/plural Vertex and Edge CRUD with 1,000-item chunking, a 65,536 logical ceiling, partial-progress errors, conditional puts, and distinct additive versus overwrite edge operations.
• Add opt-in bounded, cancellation-aware mobile retry with a fail-closed RPC matrix and one deadline budget across attempts and backoff.
• Add canonical 24-byte contribution IDs, optional automatic Add stamping, and committed-response-loss protection without replaying ambiguous mutations.
• Add geometric decaying-edge expansion with an exact initial live sum and a maintained 16-step ceiling.
• Add immutable cursor pages, asc/desc vertex and keys scans, ascending edge intersection scans, and lazy backpressure-aware page streams.
• Add exact prefix counts plus locally scoped dry-run/capped prefix Deletes that are never automatically replayed or destructively looped.
• Add complete full-text search controls, a typed search-disabled result, and a pure-Dart latest-query-wins incremental search session.
• Add sealed BFS/PPR/local-community traversal families and an immutable Graph that retains complete Edge expiration with a derived weight-only view.
• Add prefix-scoped degree ranking plus explicit immutable server and replication status snapshots.
• Add a maintained Android/iOS Flutter example with runtime token refresh, lifecycle cancellation/refetch, bounded lists, typed UI states, and all major SDK surfaces compiled in CI.
• Add Android emulator and iOS simulator real-wire gates, Android/iOS build gates, mobile security/troubleshooting guidance, and a physical-device smoke evidence checklist.
• Document the initial app-owned offline Repository contract, including exact cache freshness, durable contribution IDs, crash-safe outbox states, ambiguous-operation exclusions, threat controls, and golden scenarios; the core SDK still has no implicit persistence.
• Add the secure, injectable LanternClient transport foundation with per-call token providers, deadlines, cancellation, typed errors, and close.
• Add auth-exempt gRPC Health-v1 ping() probing with typed non-serving status errors.
