Security and Safety

Bijux Proteomics Lab builds reviewable plans, risk assessments, handoffs, and outcome records. It does not control an instrument, reserve physical materials, dispatch work to staff, or authorize an experiment. An exported plan becomes executable only through the laboratory's approved systems and accountable human processes.

Maintain the execution boundary

• Accept upstream recommendations only when their evidence references, review posture, and unresolved questions are present.
• Require explicit controls, sample and material readiness, instrument and staff capacity, risk acceptance, and cleared review gates before handoff.
• Preserve the structured refusal when a proposed assay is not responsible to run as written.
• Review LIMS field mappings and all loss notes before import. Successful export serialization does not mean the destination retained the plan's meaning.
• Record the accountable approval and local procedure in the execution system; do not infer authority from readiness or priority scores.

The package cannot verify physical custody, biosafety level, consent, instrument maintenance, reagent identity, operator qualification, or local regulatory requirements. Those controls remain mandatory even when a handoff report is ready.

Protect records and identifiers

Treat imported recommendations, free text, sample labels, material identifiers, LIMS values, and observations as untrusted data. Validate them as typed contracts and escape them in downstream query, spreadsheet, and rendering systems. Keep credentials, patient identifiers, and sensitive sample metadata out of plan rationale and diagnostic exports; use governed identifiers and least-privilege access to the source system.

Canonical serialization and fingerprints help detect changed artifacts, but they do not authenticate the approving person, prove custody, or prevent an authorized user from entering incorrect data. Use the laboratory's signed audit, access-control, and retention mechanisms for those guarantees.

Respond safely

If a handoff, plan, export, or observation may have been altered, stop execution and downstream promotion. Preserve the upstream brief, lab artifact, field mapping, imported LIMS record, observations, and fingerprints. Reconcile identifiers and determine whether any physical work already occurred.

Issue corrections as new attributable records. Never rewrite an executed plan, remove a failed observation, or promote a refused handoff. Durable history is necessary for scientific learning, incident review, and protection of people, samples, and equipment.
