docs(debug-journal): fold in the 2026-10-03 queue slice (8 candidates); mark GH#5316 fixed by PR #5319; add the sigenergy inert-power-lever, GEC unused-slot-midnight, reserve-max-validator, plugin-nav, SOH-warning, Octoplus-entity-pair, car-rate-list and update-entity rows

[springfall2008]

🤖 Automated journal flush: 8 candidates from the 2026-10-03 triage queue. All 8 were re-verified against current main (990faba1, tag v9.3.4 — the same commit the candidates were written against) before folding in. 0 were left queued.

Quality gate: ./run_pre_commit passes cspell/markdownlint on this docs-only change. The quick suite aborts at test_teslemetry_local_weekday_follows_the_base_clock — the known 00:00–01:00 local midnight-window failure documented in this journal (also seen 2026-09-22 at 00:09 BST) — and everything up to the abort passed, including ge_cloud 138/138.

Corrected existing entry

• Octopus row, GH#5316: the previous flush left it as "PR fix(octopus): keep a started IOG dispatch's half hour cheap after the car stops #5319 open" — but PR fix(octopus): keep a started IOG dispatch's half hour cheap after the car stops #5319 merged 2026-10-03 (six commits Sep 30–Oct 3 are on origin/main; verified via the commits and the new dynamic_load_car_strip_from() symbol on main). The row is now fixed-form: the strip paths (rate_add_io_slots(), dynamic_load_car_strip_feed_rates()) start from dynamic_load_car_strip_from() (plan.py) — the end of the half hour the car was last seen charging in, which Octopus bills off-peak in full — with the review-round refinements noted (confirm only from 2 minutes in; grace clock not kept across a restart). Kept the pre-fix(octopus): keep a started IOG dispatch's half hour cheap after the car stops #5319 signature for old logs.

Folded in (8)

• GH#5366 → Car charging row. car_charging_rate is read by suffixed name (float(get_arg("car_charging_rate" + postfix)), fetch.py), not index-sliced like car_charging_limit/car_charging_battery_size. An apps.yaml list is unsupported: a fresh item seeds it as an unvalidated default and float(list) raises every main-loop cycle. Workaround: per-car keys. The comma-string value stays marked suspected; the two probe traps are in the row.
• GH#5367 → Web row. Plugin endpoints work on main: on_web_start fires in WebInterface.start() before the registered-endpoint loop (re-read web.py this flush). But get_header_html() (web_helper.py) hardcodes the nav, so a plugin page is reachable only by typing its URL. Symptom pointer ("page loads but I can't reach it" = nav gap, not endpoint failure) + fix shape (opt-in plugin nav API).
• GH#5368 → Solis row. solis_automatic binds battery_scaling to the _battery_soh sensors, which publish batteryHealthSoh/100 as-is including 0 (the [Solis Cloud] batteryHealthSoh of 0 from the API silently zeroes soc_max and causes unbounded grid charging #4494 decision). The PR fix(solis): guard battery_scaling against a documented 0% SOH API response #4500 guard retains the last valid value, so the plan is unaffected; the complaint is the every-cycle repeat, an enhancement. apps.yaml battery_scaling is not a workaround; battery_scaling_auto is a different knob. Re-verified in inverter.py/solis.py this flush.
• GH#5369 → new symptom row. Dual log signature: Validation ... is not a list, but requires N entries based on num_inverters + Return bad int value [<whole list>] = a per-inverter arg read without index=. Instance inverter_reserve_max (reader inverter.py:504 predates the schema; fix index=self.id like inverter_battery_rate_min). Probe results summarised in the row.
• GH#5370 → Octopus row. The free/saving-session args read event entities (attribute="events"/"joined_events", re-verified in octopus.py this flush); the integration exposes Octoplus sessions as calendar+event pairs where only the event entity carries the attributes; both ship disabled by default. "Documented sensor does not exist" + "switch to the calendar" = the disabled-default trap, not a rename. _events-suffix mistranslation trap; old names go in January 2027.
• GH#5371 → GE Cloud row. enable_default_options() writes unused AC-charge/DC-discharge slots 2-10 times to 00:00 to disable them; on GIV-3HY the 00:00-00:00 window is live for one minute past midnight, so with force charge on at that minute the unused slots fire at full rate toward the 100% upper limit (discharge mirror: toward the 4% lower floor). It also overwrites user-set spare-slot times. Fix direction: the limits carry the disable; the generic limit branches must special-case slots 2-10. Verified by reading gecloud.py/inverter.py; the one-minute-live semantics is the reporter's field observation.
• GH#5374 → new symptom row. update.predbat_version is state-machine-only (AppDaemon set_state in expose_config(), re-verified userinterface.py:600-624) with no device/registry entry; the HA update surface that names grouped entities by device falls back to "unknown". Predbat publishes every naming attribute it can. The exact screen/HA version printing "unknown" was never pinned — the row says to ask the reporter. Not fixable from Predbat.
• GH#5376 → Sigenergy row. Every power lever on SIGCLOUD is silently inert on main: send_battery_command() sends the six optional power/priority fields (chargingPower, pvPower, maxSellPower, maxPurchasePower, chargePriorityType, dischargePriorityType) at the top level of the payload while the required fields sit inside commands[0] (since cba12cc3, first released v8.36.11; re-verified sigenergy.py:1137-1157 this flush). Hardware evidence: the reporter's live MQTT log and flat full-rate charging in the issue. The sigenergy tests assert the top-level shape, so suite-green was meaningless for this surface; a fixed test must assert inside [0] and top-level absence. Open PR fix(sigenergy): send the optional command fields inside commands[] #5377. Suspect-not-verified: Sigenergy Cloud: Freeze Export commands self-consumption mode without capping charge power, battery charges from solar instead of holding SoC #4761's freeze-export reasoning and freeze_export_hold have never acted with real effect until a hardware re-test after PR fix(sigenergy): send the optional command fields inside commands[] #5377 merges.
