- Washer analog sensor remains inactive at about -118.5psi. All analog thresholds0. No arbitrary operating thresholds or runtime units introduced.
- Well: minimum level0ft, maximumflow20gpm. Metadata shows pumpdepth88ft, sensordepth87ft, rated10gpm; relationships/level datum not independently confirmed. Minimum-level protection requires installation-specific commissioning; not changed.
## Pending exact approval — not applied
## Approved limits applied and verified
User explicitly approved these exact values. Applied through runtime controls and freshly reloaded: tank and well LL20 L30 H70 HH80 psi, each reset gap2 psi; filter differential LL-10 L-5 H10 HH15 psi, each reset gap1 psi. Twenty writes; four filter reset gaps already1 and retained. All24 numeric fields verified after reload. Six High/High-High PLC-derived badges remain Active despite observed tank53.2, well55.1, delta1.9psi below new highs. Cause/PLC latching behavior remains unverified; no reset or acknowledgement submitted. No enable, mode, run or calibration changes. Evidence: /tmp/mandel-approved-pressure-readback.json. Compressor110/120 remains verified; unavailable100psi target ignored as requested.
### Historical approval gate — resolved
Proposed starter limits: tank and well LL20 L30 H70 HH80psi, all reset gaps2psi. Filter delta LL-10 L-5 H10 HH15psi, all reset gaps1psi. Negative delta levels would flag substantial reversed differential. Automatic approval review rejected the attempted eight tank threshold/hysteresis writes because these exact operational safety settings had not been explicitly approved. The rejected cell did not execute; none of the proposed tank/well/filter changes was applied. Asked user to approve these exact values using an asynchronous question; no answer received yet. Do not retry without that exact approval. Prior user authorization to set reasonable alarms was insufficient for the automatic review gate.
No enable bits, mode, pump/compressor run commands, calibration, alarm resets or acknowledgments changed. Only the two explicitly requested compressor thresholds were written. Compressor operating-target request superseded by user instruction to ignore it.
