| What does the bot remember? | Relevant prior context. | Typed facts with provenance, tenant scope, confidence, and temporal validity. |
| Can we prove when it learned it? | Usually vendor/log dependent. | Ledger timestamp, hash continuity, and exportable evidence. |
| Can a bad memory be isolated? | Often update/delete semantics. | Deprecate, dispute, tombstone, or require consensus before acting. |
| Can several agents share truth? | Memory sharing depends on the app. | Agent registry, heartbeat, WBFT voting, handoff, and shared ledger. |
| Can research survive chat loss? | Only if app persists it well. | Research crystals: source, claim, synthesis, confidence, and verification state. |
