Summary

Root cause (two compounding bugs): 1. DuckBrain's domain field is a strict enum {person, event, concept, message, config, raw_note}. "status" is not in it, so POST /api/memories returns 400 VALIDATION_ERROR and persists nothing. 2. The post-write check verified key presence, and the key already existed from earlier ticks — so the rejection was mistaken for success.

Fix: - domain=event for status/narration keys (/project/<ns>/status) - domain=config for counter/config keys (/project/<ns>/status/idle-ticks) - A validated Python helper that refuses bad domains client-side, requires HTTP 201, and verifies by exact content + fresh timestamp on page 1 (limit=50, never pages past page 1, since high offsets can be empty even when hasMore=true).

Verification performed: the live API required an x-api-key absent from the sandbox, so I ran the exact client logic against a contract-faithful mock reproducing the strict-enum 400, the 201 success, and newest-first pagination. Results: - domain=event / domain=config → 201, content verified on page 1 - domain=status → exact production 400 VALIDATION_ERROR - Content verification rejected missing content even though the key existed — the precise false-success trap, now closed.
