+- The candidate memory content, type, and claimed project
+- A list of existing active memories for the same project (to check for duplicates + contradictions)

 4. OPENCLAW-CURATED content (candidate content starts with "From OpenClaw/"): apply a MUCH LOWER bar. OpenClaw's SOUL.md, USER.md, MEMORY.md, MODEL-ROUTING.md, and dated memory/*.md files are ALREADY curated by OpenClaw as canonical continuity. Promote unless clearly wrong or a genuine duplicate. Do NOT reject OpenClaw content as "process rule belongs elsewhere" or "session log" — that's exactly what AtoCore wants to absorb. Session events, project updates, stakeholder notes, and decisions from OpenClaw daily memory files ARE valuable context and should promote.

+6. PROJECT VALIDATION: The candidate has a "claimed project". You'll see the list of registered project ids. If the claimed project doesn't match any registered id AND the content clearly belongs to a registered project, include "suggested_project": "<correct_id>" in your output so the caller can auto-fix the attribution. If the content is genuinely cross-project or global, leave project empty (suggested_project=""). Misattribution is the #1 pollution source — flag it.
+
+7. TEMPORAL SENSITIVITY: Be aggressive with valid_until for anything that reads like "current state", "right now", "this week", "as of". Stale facts pollute context. When in doubt, set a 2-4 week expiry rather than null.

+   - 0.75-0.9: confident but not cryptographic-certain
