+## Latest investigation — Lazy B Well 3 timer repair awaiting PLC mapping
+
+On October 21, 2026, inspected both Well 3 timer configuration dialogs and Water System register definitions. Original wellNW1 display/write bindings remain unchanged. Water System table has 1,660 entries; searches tss, totalTmr, runtime and wellNW1 returned no matches. No configured Well 3 timer replacement was verified. Enabled iWell3Vol_rtDaily[0]/[1] are daily counters with units unverified; disabled well3Power_total_onTime is not a proven lifetime counter substitute. Disabled well3_i_UTS has blank description and Well Shack PLC address well3.i.UTS; purpose/units unknown. Asked the user for the two correct PLC tags, units and lifetime counter write semantics. No page/register saves, counter resets, polling changes or operational writes. Updated LAZY-B-GUIDE.md and shared study/project/handoff plus cloud notes with these findings. Next step: obtain verified mapping; then fix only timer display/write bindings, preserve appropriate conversions, save and verify persistence without resetting hours.

+## Previous completed change — East Water Well 30 trend label
 
 On October 21, 2026, corrected production https://www.atomhmi.com/site_kav_east_water/page_wells, Trend element 95ec8b60-2fe9-462d-8222-f2c069e41560. Renamed only the series bound to water:g_well30_flow_out_eu from Well 29 to Well 30. Saved the element/page, freshly reloaded/reopened configuration, and verified only the series name differs among 11 captured form controls (10 series retained). The live chart legend separately shows Well 29 and Well 30. Register, scale gpm, color #b8c564, axes, range buttons and navigator preserved; no register/operational writes. Updated KAV-GUIDE.md, SITE-STUDY.md, PROJECT.md and the relevant cloud guides. Local screenshot: /tmp/kav-east-water-well30-trend-fixed.jpg (not committed).

 ## Remaining findings — unchanged by the KAV corrections
 
-1. Lazy B Well 3: Time Since Start and editable Hours use water:wellNW1_tssTmr / wellNW1_totalTmr, unlike other Well 3 bindings.
+1. Lazy B Well 3 timer repair awaits correct PLC tags/units/write semantics; current wellNW1 references have no matching configured Water System registers. See latest investigation and LAZY-B-GUIDE.md.
 2. Lazy B: duplicate main/Main navigation targets; M03 PID Tn suffix KP; Loadout internal 100% Button name on an 80-value command. Internal names are not behavioral proof.
 3. Lone Pine dryer uses legacy (Dont Use) components. Inspect supported semantics before reusing/migrating.
 4. Alarm latching, notification policies, PLC interlocks and operational write behavior were not audited here.

 Current flow/level chart navigator is water:aiWell3Flow_eu. Historical level navigator is water:aiWell3LvlAgg_Past24Avg, default button index 1. The information/map/report root is separate; preserve it during control-page replacement and do not publish its location details unnecessarily.
 
-**Unresolved timer reference:** Well 3's Time Since Start reads `water:wellNW1_tssTmr * 1000`; editable Hours reads `water:wellNW1_totalTmr * 1000` and writes `value / 1000` to `water:wellNW1_totalTmr`. These names differ from the Well 3 family. Verified in copied JSON; intended PLC mapping remains unknown. No reset/write was made.
+**Timer repair pending verified PLC tags — October 21, 2026:** rechecked production Well 3 (`well_3`). Time Since Start, element `6e6f612c-c2e5-4ee9-a468-849e6191b523`, still reads `|{register:water:wellNW1_tssTmr}| * 1000`, non-editable, HH:mm:ss, blank updateRegister. Hours, element `4e613f5b-e0e3-4526-88dd-b9a81695d75e`, still reads `|{register:water:wellNW1_totalTmr}| * 1000`, editable, writes `value / 1000` to `water:wellNW1_totalTmr`, format d [days] HH:mm. Captured both original configurations and left them unchanged. The Water System (water) register table contained 1,660 entries; searches for tss, totalTmr, runtime and wellNW1 returned no matches. The Well 3 family has no verified replacement for either timer. Existing enabled `iWell3Vol_rtDaily[0]` / `[1]` are daily counters, not established equivalents of time-since-start or lifetime Hours; units were not independently verified. `well3Power_total_onTime` exists disabled and is likewise not a verified replacement. Disabled `well3_i_UTS` has blank description, slave Well Shack 2080-LC20-20QBB, address well3.i.UTS; its role/units do not establish a timer binding. Do not invent well3_tssTmr/well3_totalTmr mappings or enable an unrelated counter. Requested the correct PLC tags, units and lifetime-counter write semantics from the user. No page/register saves, counter resets, polling changes or operational tests were performed.
