* PR-2 MemoryCore Facade Test Suite
|
||||
*
|
||||
* Run: node --test test/memory-core/facade.test.mjs
|
||||
*
|
||||
* Tests the MemoryCore facade contract:
|
||||
* 1. Module importable
|
||||
* 2. health() returns ok:true
|
||||
* 3. stats() returns stable structure
|
||||
* 4. search() returns unified contract
|
||||
* 5. get("MEMORY.md") returns unified contract
|
||||
* 6. get("missing-file") returns ok:false
|
||||
* 7. write() only writes to test namespace
|
||||
* 8. delete() only deletes from test namespace
|
||||
* 9. Does not modify real MEMORY.md
|
||||
* 10. Does not change memory_search old tool behavior (verified by baseline)
|
||||
* 11. Does not change memory_get old tool behavior (verified by baseline)
|
||||
* 12. production-check still passes (verified in facade-health.test.mjs)
