Context Steward -- Memory With an Expiration Date

More memory is not the same as better continuity.

Context Steward governs the lifecycle of agent and project context. It separates verified facts from dated observations, decisions, inferences, preferences, and open questions; then it checks drift, preserves conflicts, and produces a handoff another operator can actually resume.

What you get

• A provenance-rich context ledger
• Drift-risk labels and targeted re-verification
• A conflict register instead of silent contradiction resolution
• Compact handoffs with objective, proven state, blockers, approvals, and next action
• Explicit keep, promote, archive, redact, and delete proposals
• An exclusion record showing what was intentionally left out

This goes beyond Recall's memory retrieval and Baton's session checkpointing: it decides what deserves to persist, what needs fresh evidence, and what should expire. It never stores secrets or deletes source material without an approved, recoverable plan.
