Test record · November 14, 2026

What is tested, and what is not yet.

We keep one record of what the software has actually been seen to do, and we publish it. A claim on this site is allowed only if it has a row here. Nothing has been tested on a customer device yet, and the record says so.

Run on our build server
A real run of the real software on the server that builds each edition, standing in for the customer's device.
Automated test
Checked by a test that runs every time the code changes.
Not yet tested
Written, but not yet run on the real device. We do not claim it works until it has been.

Working with no internet

CapabilityStatusHow we know
The library, search, place search and maps answer with all outside network access blockedRun on our build serverThe preview runs under a rule that denies every address except the machine itself. An outside download address timed out; the library answered.
The browser asks nothing outside the libraryRun on our build serverThe map page was loaded in a fresh browser: 19 requests, all to the library, none failed.
The reader bundle contains no outside addressesAutomated testAn audit of the built reader runs on every build.

Reading and searching

CapabilityStatusHow we know
English and Spanish search, including a Spanish query finding English articlesRun on our build serverA search for “monóxido de carbono” returned the Spanish articles and the English ones for carbon monoxide.
Encyclopedia articles open inside the readerRun on our build serverThe Spanish medical encyclopedia was read through the reader on a separate, sandboxed address.
Draft cards are never shown as guidance, and sold editions carry no draftsAutomated testThe release build refuses them; the current drafts are labelled as unreviewed.
Search inside PDF documentsNot yet testedDocuments are found by title today. Text search inside them is not built yet.

Maps

CapabilityStatusHow we know
Street-level map display with local fonts and icons, coverage boundary and data dateRun on our build serverArlington and Fort Worth rendered with labels, icons and road shields; a town outside coverage showed the warning.
Place search for Texas, tolerant of missing accents and partial namesRun on our build server“San Anto”, “Grand Prairie” and “leon valley” each found the right place.
Turn-by-turn directionsNot yet testedNot included. Distances are straight lines and the map says so.

Integrity of each edition

CapabilityStatusHow we know
Every download is checked against the publisher's own checksumRun on our build server14 objects verified against published SHA-256 or MD5 digests before entering the store.
The edition is signed and the reader checks the signatureRun on our build serverThe reader reports a valid signature. Today's key is a development key; sold editions use a production key made offline.
An edition copied to a drive is read back and compared file by fileRun on our build server858 of 858 files re-hashed from the copy.
A release cannot contain secrets, household data or unlisted filesAutomated testThe release audit fails the build if it finds any.

On the real hardware

CapabilityStatusHow we know
The box's own Wi-Fi: joining from iPhone, Android, tablets and laptopsNot yet testedThe installer is written. It has not run on a Raspberry Pi yet.
Start-up time from a cold power-onNot yet testedWill be measured ten times and published.
Ten devices reading and searching at onceNot yet testedWill be measured for fifteen minutes with temperature and throttling recorded.
Power draw and battery runtimeNot yet testedWill be measured with a meter. No battery figure is claimed before then.
Recovery after power is pulled mid-searchNot yet testedPlanned: pull power, restart, verify the edition.
Library Drive on Windows, macOS and LinuxNot yet testedBuilt for all three. Not yet run on the target computers, and not yet code-signed for Windows and macOS.
First-time users reaching an article within three minutesNot yet testedPilot households have not started.
