VC-SOP-0102 — Watch Handover & Greenhouse Grid State Read-Back
The formal shift-change protocol between greenhouse watch teams: a structured, item-by-item verbal read-back of grid zone states, open alarms, in-progress procedures, and specimen watch items so that nothing is dropped across the four watches of an operating cycle.
No watch ends until the relief acknowledges. The off-going Watch Commander retains full accountability for the greenhouse grid until every checklist item in Section 6 has been read out, confirmed-back verbatim by the on-coming Commander, and the handover is signed in the Mycelial Data Fabric (MDF). A silent or assumed handover is a reportable deviation. If the relief is absent at the boundary, the off-going watch holds over — the grid is never left unwatched.
1. Purpose
To define the controlled procedure by which custody of the Sector-7 greenhouse grid is transferred between consecutive watch teams. The objective is zero loss of operational awareness across the boundary: every alarm, every paused or running procedure, every specimen on a watch list, and every degraded subsystem is positively transferred — read out by the off-going Commander and confirmed back, in the speaker's own words, by the on-coming Commander.
2. Scope
Applies to all four watches of the operating cycle (Dawn 06:00–12:00, Day 12:00–18:00, Dusk 18:00–00:00, Vigil 00:00–06:00) across greenhouse grid zones G-01 through G-24, the Phyto-Synthesis Bay annex, and the climate plant under VC-SOP-0212. Covers the Watch Commander, the lead Cultivar on duty, and the Drone Operations console per VC-SOP-0301. Specimen-level cultivation actions are governed by VC-SOP-0101; this SOP governs only the transfer of state, not the underlying work. Emergency handover during an active breach is superseded by VC-SOP-0911.
3. Definitions
| Term | Definition |
|---|---|
| Watch | One of four six-hour custody periods over the greenhouse grid within an operating cycle. |
| Read-Back | The on-coming Commander repeating an item in their own words to demonstrate understanding; not a passive "copy." |
| Grid State Read | The zone-by-zone summary of climate, hydro-loop, canopy, and containment status pulled live from the PhytoSense Mesh. |
| Watch Item | A specimen, zone, or subsystem flagged for heightened attention during the watch (e.g. a recovering GCL-3 cultivar). |
| Hold-Over | Off-going watch remaining on station past the boundary when no qualified relief is present. |
| Handover Log | The signed MDF record of the transfer, time-stamped and witnessed by CHLORA. |
4. Responsibilities
| Role | Responsibility |
|---|---|
| Watch Commander — Off-Going (Owner) | Prepares the handover brief; reads every Section 6 item; retains accountability until acknowledgement; owns this SOP. |
| Watch Commander — On-Coming | Performs verbatim read-back; challenges any ambiguous item; accepts custody by signature. |
| Lead Cultivar on Duty | Confirms in-progress cultivation steps and dosing windows; flags specimen watch items. |
| Drone Console Operator | Reports swarm status, charging state, and any tasking that crosses the watch boundary. |
| CHLORA | Pre-stages the live grid state read, witnesses the handover, time-stamps and locks the Handover Log, raises a deviation if no acknowledgement is recorded by the boundary +10 min. |
5. Equipment & Pre-Checks
- Watch console with live PhytoSense Mesh grid view and the MDF Handover Log open
- CHLORA-generated pre-handover state pack (auto-built at boundary −20 min)
- Open-alarm queue cleared of stale acknowledgements and triaged by severity
- Specimen watch-list current; any GCL-3+ item annotated with its monitoring cadence
- Drone swarm status board and charge-state read from VC-SOP-0301
- Both Commanders physically present at the watch console — no remote or proxy handover
6. Handover Read-Back Checklist
Every item below is read out by the off-going Commander and confirmed back by the on-coming Commander before custody transfers. The confirm-back rule states what an acceptable read-back must contain — a bare "copy" is not acceptable for any starred item.
| Item | Source | Confirm-Back Rule |
|---|---|---|
| Grid zone states (G-01…G-24) | PhytoSense Mesh live read | Read back the count of nominal zones and name every zone not nominal with its state. |
| Open alarms | MDF alarm queue | Read back each unresolved alarm by ID, zone, severity, and current action — verbatim, no rounding. |
| In-progress procedures | Cultivar / console | Read back the SOP ID, step number reached, and the time the next step is due. |
| Specimen watch items | Watch-list board | Read back each specimen ID, its GCL grade, and the next monitoring time. |
| Climate plant status | VC-SOP-0212 | Read back any setpoint deviation and whether the plant is in auto or manual. |
| Hydro-loop / dosing | Loop console | Read back any loop on manual, any dosing window open, and any overpressure flag per VC-SOP-0231. |
| Drone swarm tasking | Drone console | Read back active tasks, drones offline, and aggregate charge state. |
| Degraded sensors / mesh gaps | Mesh diagnostics | Read back each blind zone and its compensating manual-check interval. |
| Standing instructions from CBO | Directorate log | Read back each standing order verbatim; unread orders block acceptance. |
Starred-equivalent rule. Open alarms, in-progress procedures, GCL-3+ watch items, and standing CBO instructions are critical-transfer items: if the on-coming Commander cannot read any of these back accurately, the item is re-briefed until correct before the handover may proceed.
7. Procedure
7.1 Pre-Handover Preparation (boundary −20 min)
- CHLORA assembles the state pack: grid read, alarm queue, in-progress procedure list, watch items, and degraded-subsystem list.
- Off-going Commander reviews the pack against their own watch notes and resolves any discrepancy before the relief arrives.
- Off-going Commander clears or annotates every stale alarm acknowledgement so the relief inherits a clean queue.
7.2 Face-to-Face Read-Out
- Both Commanders take position at the watch console with the live Mesh view and the open Handover Log.
- Off-going Commander reads each Section 6 item in order, top to bottom, without skipping nominal zones.
- On-coming Commander performs the confirm-back per the rule for that item; off-going Commander corrects any error before advancing.
7.3 Challenge & Resolve
- On-coming Commander challenges any item that is ambiguous, internally inconsistent, or conflicts with the live Mesh read.
- Unresolved challenges on a critical-transfer item block acceptance; escalate to the Cultivation duty manager or, for containment, the Containment Officer.
- Lead Cultivar and Drone Operator confirm their respective in-progress items directly to the on-coming Commander.
7.4 Acceptance & Custody Transfer
- When every item is confirmed back, the on-coming Commander states "I have the grid" and signs the Handover Log in the MDF.
- Off-going Commander counter-signs; CHLORA time-stamps and locks the record.
- Accountability transfers at the moment of the locked record — not at the clock boundary.
7.5 Hold-Over Contingency
- If no qualified relief is present at the boundary, the off-going watch holds over and CHLORA raises a staffing deviation to the duty manager.
- Hold-over beyond 90 minutes requires Watch Commander relief from the on-call roster; fatigue limits per
VC-HR-0044apply. - The grid is never left without an accountable Commander, regardless of staffing state.
7.6 Quality Checkpoints
- State pack reconciled against watch notes before read-out
- Every Section 6 item read and confirmed back — no item marked "copy" only
- All critical-transfer items read back accurately or re-briefed
- Handover Log signed by both Commanders and locked by CHLORA
- Custody transfer time-stamped within boundary ±10 min or deviation raised
8. Records
- Signed Handover Log per watch boundary (MDF, retained 3 years)
- CHLORA state pack snapshot attached to each handover
- Challenge-and-resolve notes for any contested item
- Hold-over and staffing deviation reports
- Standing-instruction acknowledgement trail
