project-memory-guard（项目内存卫士）

Project Memory Guard

Validate every memory write against project and writeback rules. Prevent contamination and schema drift.

Input

Required fields:

• raw_content — the content attempting to enter project memory
• candidate_project_id — the project being written to
• memory_type — type of memory: note, finding, task, summary, record, etc.
• source — where this came from: user message, paper, tool output, etc.
• timestamp — ISO-8601 timestamp of when the content was created
• confidence — confidence score 0.0–1.0 for project assignment

Output Schema

decision: "accept" | "reject" | "reroute"
destination: string | null          # project_id or "inbox" or null
normalized_record: object | null    # cleaned record if accepted/rerouted
contamination_risk: "none" | "low" | "medium" | "high"
missing_fields: string[] | null
reason: string

Hard Rules

Reroute Destinations

• inbox — unverified content waiting for manual review
• cleanup — ambiguous content needing disambiguation
• Specific project_id — when rerouting to a known project

Normalization

When decision is accept or reroute, normalize the record:

• Strip identifying metadata not in schema
• Add validated_at timestamp
• Add guard_version = "1.0"
• Preserve original raw_content in normalized_record.raw

Failure Handling

If uncertain about any field:

• Do not guess project_id or memory_type
• Set decision = "reroute" with destination = "inbox"
• List missing_fields explicitly
• Explain in reason

Never force acceptance when validation fails.
