C1-P4 · CNHL-2026-004

undated · Commissioned → C1-P4

Commissioned into C1-P4, its first night with measurements. Earlier catalog nights aren't in this record. The pack ID was assigned on 2026-10-08.

2026-10-09 · Rest test started · C1-P4 → C1-P4

7-day rest test cycle 1 (suspect Cell 1); day-0 = storage_end of short DX8 top-up; 7-day reading due 2026-10-16; Rules v3

2026-10-09 · Entered Rest pool · C1-P4 → C1-P4

Off every board until the 7-day reading on 2026-10-16.

2026-10-17 · Left Rest pool · C1-P4 → C1-P4

Left the rest pool under rules v6 (approved 2026-10-17): the rest pool is retired. Back in rotation at its home slot (DX8-1 Channel 2, after C1-P3) and on the C1 parallel board from its next storage night. Rest test RT-004-1 completes in place from the first reading of that storage log, if it has not flown since 2026-10-09.

Rules v3: Cell1 gap >=60 mV on 2 of last 3 (last 3 = 166/49/93 mV); >=100 on 3/13. Evidence (last 2026-09-27: IR avg 2.88 spread 0.65 mOhm, S_R 17.25; floor 3603 (Cell1); low-cell gap 93 mV)

Parallel Off (Rest pool) | Watch; rest test RT-004-1, 7-day reading due 2026-10-16; not charged during test

Rest pool (owner decision 2026-10-09): off all parallel boards and not charged until the 7-day reading; returns by rest-test result under Rules v3 (PASS/BORDERLINE/FAIL + service-tier rules). Status/grouping change only, no new measurement.

rest-test day-0 measurement 2026-10-09-restday0: start floor 3786 mV (Cell1), imbalance 5 mV, low-cell gap 4 mV, rest 22.734 V; IR avg 3.167 spread 0.9 mOhm, S_R 19.0; short top-up from near storage, rest duration unknown - not evidence for/against self-discharge; 7-day reading due 2026-10-16

Parallel Go: on the C1 board | Watch (rest test RT-004-1 completes in place)

Back in rotation under rules v6 (approved 2026-10-17): the rest pool is retired. Returns to its home slot (DX8-1 Channel 2, after C1-P3) and to the C1 parallel board on its next storage night. Rest test RT-004-1 (Cell 1) completes in place from the first reading of that storage log, if it has not flown since 2026-10-09; the drop is scaled to 7 days (pass 10 mV or less, borderline 10 to 30 mV, fail over 30 mV, and a fail is a note). Watch is a note only.

Parallel Go: on the C1 board | Watch (self-discharge check RT-004-1)

Re-graded under rules v7. No pull sign in the data. The open rest test RT-004-1 (Cell 1) is now the self-discharge check: it completes from the first line of its next storage log if the pack has not flown since 2026-10-09. The low-cell gap is a performance note.

Parallel Go: on the C1 board | In service

Rules v7: self-discharge check passed (2 mV in 9 days). Watch cleared.
