Deepest on record — 28.06mm, past the 24.4 trigger and the +25 PWP marker; 9 days zero water (ec[Top] empty all window). Drying ~2.9mm/day; the 1.83mm subsoil buffer is now eroding too (+0.33/48h). Hand-watering was NOT done yesterday — 6th day advice unactioned. Hand-water ~5–6 L/tree TODAY + repair the Top valve/solenoid (fault isolated Jul 24); verify the next dose in ec[Top].

Hold is WORKING — 0 flow Jul 25/26 after the 24L Jul 24 dose; topsoil drying back normally (3.51 → 10.54, big sawtooth expected) and subsoil draining −4.81 → −4.14 (~0.67mm/day). Deep D4–D6 still saturated (D6 −3.48). No dose until topsoil >15 AND subsoil ≥−3 (est. ~Jul 28), then cap ~15L. Phytophthora collar inspection THIS WEEK.

Risk Matrix
| Issue | Sev | When | Action |
|---|---|---|---|
| TOP young trees PAST PWP-equivalent — 28.06mm, 9d zero water | CRIT | NOW | Hand-water TODAY ~5-6 L/tree; confirm moisture drop tomorrow |
| Top valve/solenoid fault — ISOLATED (Bottom fired, Top didn't) | CRIT | NOW | Repair/replace Top zone line today; verify dose in ec[Top] |
| Execution latency — 6 consecutive days advice unactioned | HIGH | NOW | Assign a named person; confirm completion same day |
| Subsoil buffer eroding — 1.83mm left, ~2-3 wk at current draw | HIGH | WEEK | Restore Top irrigation before the buffer is gone |
| Phytophthora — Bottom deep layers re-flooded twice/8d (D6 −3.48) | MOD | WEEK | Collar/trunk inspection on mature trees |
| Ecowitt station blind 49d (24th flag, 23 escalations failed) | MOD | MONTH | Physical repair OR replacement PO only |
