Kuwala / Oasis: selected live document checks 9 October 2026 The live station was running release 970dfe6 with the amber-and-graphite interface and shared Kuwala / Oasis sun mark. Its current PDF trial collection contained 85 documents. These are two selected development checks, not a representative evaluation or an accuracy rate for the collection. They do not establish field usefulness or performance of the complete solar station. 1. A practical battery-monitor question Question submitted: @repair What does the battery monitor use to estimate state of charge? Original document: Manual – BMV-712 Smart: Battery monitor, Victron Energy. Rev 19, August 2026. PDF page 22, printed page 18, section 5.1. https://oasis.kuwala.space/library/documents/victron-bmv712-2026/pdf#page=22 Publisher: https://www.victronenergy.com/battery-monitors/bmv-712-smart Source quotation: “The battery monitor continuously measures the current flow in and out of the battery.” Observed result: partly supported; explanation needs more precision. Oasis found the correct manual. Its first bullet explained that the monitor integrates current flowing in and out over time, with adjustments for the Peukert effect and charge efficiency. This is supported on PDF page 22. Its second bullet described voltage, tail-current and detection-time settings as inputs to calculating state of charge, citing PDF pages 27 and 56. Those conditions detect full charge and synchronize the estimate to 100%. They should be distinguished from the parameters used in the charge calculation, including capacity, Peukert exponent and charge efficiency. A more precise explanation of that second point is: Voltage, tail-current and detection-time conditions identify full charge, allowing the monitor to reset its state-of-charge estimate to 100%. This check shows why locating the correct source and faithfully explaining it are separate things to review. It is not recorded as a clean pass. 2. A practical circle-measurement question Question submitted: @learning How do I find the circumference of a circle? Original document: Math for Trades: Volume 2, Chad Flinn and Mark Overgaard. BCcampus, 2021. CC BY 4.0 except where otherwise noted. Publisher: https://opentextbc.ca/mathfortrades2/ https://oasis.kuwala.space/library/documents/bc-maths-trades2-2021/pdf#page=111 The formula appears on PDF page 111 (printed page 97): “Circumference = π × diameter” Observed result: both answer statements supported by the cited page. Oasis gave C = π × D, with D defined as the diameter. It also explained that if the radius is known, the diameter is twice the radius: D = r × 2. Both statements cited PDF page 113 (printed page 99), which explicitly contains the circumference formula and the radius-to-diameter relationship in a worked example. The original page was visually checked. https://oasis.kuwala.space/library/documents/bc-maths-trades2-2021/pdf#page=113 The public website adds a simple illustration: a pipe 10 cm in diameter has a circumference of about 31.4 cm. That illustration is website copy, not part of the captured Oasis answer. The screenshot oasis-maths-answer-20261009.jpg records the actual live response. The chat ready-state and Knowledge catalogue screenshots were also refreshed from the live service on 9 October 2026. What these checks leave open Broader checks still need varied questions, follow-ups, missing information, difficult PDFs and independent review of source faithfulness. Comparison with direct PDF use and observation with an intended host are separate next steps. The earlier 8 October notes retain unsuccessful and partial cases: https://kuwala.space/documents/development-checks-2026-10-08.txt
