docs(debug-journal): fold in the 2026-09-25 queue slice; correct the springfall2008#5103/springfall2008#5186/springfall2008#5053-adjacent entries

Folded (13 entries from the 15-candidate slice, all re-verified against origin/main 130596b):
- Load ML row (GH#5075, PR springfall2008#5112 open draft): is_valid() can report active for a never-trained
  model; training_timestamp is None is not a sound never-trained test (legacy saved models);
  train() stamps at the end of every curriculum pass, so an abort leaves fresh stamps that
  suppress the ml_max_model_age_hours retrain. Normalisation-statistics skew stays suspected.
- Octopus row: GH#5144 overlapping DIRECT/NON_DIRECT_DEBIT rows, minute_data last-row-wins and
  the period-to-period flip - fixed in PR springfall2008#5145 (filter_payment_method, keeps nulls).
- Car charging row: GH#5146/GH#5151 the two different Hold-for-car gates (execute.py live block
  vs prediction.py plan gate), deliberate export-window exemption test-codified
  (discharge_car_full_bat2), read-only users never see the status sensor's annotation.
- Sunsynk/DEYE row: PR springfall2008#5150 control_active persistence + upgrade-cache inference; the in-code
  press every cycle comment is wrong (both press sites change-gated, post-restart re-commit is
  is_hm_format-only); GH#5156 TOU padding truncation fixed in tou_schedule.py _padding_segments.
- Solis row: GH#5152 the hold lever is the window-scoped timed current (standing
  battery_discharge_current never driven); PR springfall2008#5189 adds the rated-current cap (GH#5187).
- Predheat row: GH#5153 no Fahrenheit conversion in get_weather_data + the optional
  heating_energy age bug pinning minute_data_age to 0.
- Teslemetry row: GH#5157 forced re-assert implemented (FORCED_ASSERT_SECONDS = 2h, dedupe
  bypassed, tariff excluded); tbc_control default on since PR springfall2008#5188.
- Keep section: GH#5162 manual_soc floor penalty is import-rate-weighted, so inert inside 0p
  windows; the manual_soc_max ceiling is export-rate-weighted; manual_charge lookalike trap.
- New Kraken row: GH#5166/PR springfall2008#5167 EDF 400-on-day/night vs Octopus 200-empty;
  KRAKEN_REST_RATES_UNAVAILABLE_STATUSES; the (None, None) tuple contract and the
  failures_total double-count, both fixed in the merged PR and kept as mechanisms.
- New Manual rates row: GH#5168 day_of_week stamped across the whole rate horizon, fixed in
  PR springfall2008#5173; end ':59:59' final-minute trap and the metric_future_rate_offset test pin kept.

Dropped: 5169-5053-cache-now-on-main (already covered by the redaction entry and the GH#5063
premise bullet; its lock-lazy-init nugget is recorded as a fact of the merged PR springfall2008#5171 mixin).

Corrected by the merge scan: GH#5103 fixed in PR springfall2008#5109 (hourly settings refresh + the new
check_ems_inverter_slots warning); teslemetry_tbc_control default on (PR springfall2008#5188); the
log-redaction cache moved into the LogRedaction mixin (log_secrets.py, PR springfall2008#5171).
