## Description
|
|
|
|
Implement the `export()` and `toJSON()` methods on `TaskGraph`. These wrap graphology's `export()` to produce `TaskGraphSerialized` output.
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [x] `export(): TaskGraphSerialized` — wraps `graph.export()` and validates the output conforms to the `TaskGraphSerialized` schema
|
|
- [x] `toJSON(): TaskGraphSerialized` — alias for `export()` (enables `JSON.stringify(graph)` to work)
|
|
- [x] Exported data includes all node attributes and edge attributes (including `qualityRetention`)
|
|
- [x] Round-trip: `TaskGraph.fromJSON(graph.export())` produces an equivalent graph
|
|
- [x] Unit test: create graph, add tasks/edges, export, round-trip through fromJSON, verify equivalence

## Notes
|
|
|
|
Straightforward implementation. `export()` delegates to `this._graph.export()` and casts to `TaskGraphSerialized`. `toJSON()` is a simple alias so `JSON.stringify(graph)` works automatically.

## Summary
|
|
|
|
Implemented `export()` and `toJSON()` methods on `TaskGraph` class.
|
|
- Modified: `src/graph/construction.ts` — added export() and toJSON() methods
|
|
- Modified: `test/graph.test.ts` — added 10 tests covering export, toJSON, round-trip, JSON.stringify integration
|
|
- Tests: 266, all passing (lint clean) |
