Survey Corps Boundary Monitoring Protocol — Threshold Class Stations

SURVEY CORPS BOUNDARY MONITORING PROTOCOL CLASS: THRESHOLD STATIONS Issuing Officer: Chief Surveyor Wren Ansell, Survey Corps Standards Office Issued: 2811 UCSD Current version: 2.3

---

Section 1 — Purpose

A Threshold-class station sits close enough to a Concordant boundary that ordinary surveying becomes a matter of public safety. This protocol governs all boundary-monitoring activity at stations within 500 survey-units of a confirmed boundary.

Its purpose is to:

1. Preserve baseline measurements of boundary position and stability.
2. Report significant changes in boundary position or behaviour.
3. Support research into Concordant boundary characteristics.

Section 2 — Instrument Standards

Each Threshold-class station must maintain at least two independently calibrated chronometers. Any discrepancy greater than one second between those chronometers is to be logged as an instrument anomaly and investigated.

[Note in margin, handwriting, unsigned: "The two-chronometer requirement was added in 2809 UCSD after an incident at Station Kelvar where a 3-minute discrepancy went undetected for six months. The requirement has never been followed up with any guidance on what to do when the discrepancy does not resolve on recalibration."]

Section 3 — Reporting

When an anomalous reading is detected, staff must file an Incident Report within 24 hours. The station manager reviews that report and forwards it to the regional survey office only if the manager determines that external review is required.

Station managers retain full authority to classify Incident Reports as resolved without external review.

Section 4 — Authorised Activities

Survey teams at Threshold-class stations may conduct:

• Physical inspection of boundary-proximate areas
• Instrument reading and logging
• Material sampling in boundary-proximate zones

Survey teams may not conduct:

• Etheric-layer assessment without a certified analyst assigned to the team
• Boundary contact procedures without regional office authorisation

Appendix: Certified Analyst Classifications

A certified boundary analyst is any being with documented training in Etheric-layer assessment methods and certification from a recognised training body.

[Note: as of 2826 UCSD, Threshold Station has no certified analyst on its establishment. The Krenyi analyst assigned to the new survey team (Syra) holds certification from a non-survey-corps body. Her certification status within survey corps jurisdiction is pending review.]
