Product updates

Program update 1 adds two calculator-tested Python programs for physics and chemistry, each with a branded opening, source, browser screen preview, and direct download.

• Added: DuckieDai Final Velocity 1.0.0 calculates vf = vi + a*t from signed velocity and acceleration with nonnegative elapsed time. Reviewed source SHA-256: 82f7574b4ab96769f6b83867c3a9ce41d9c849f5f3f1065853d1f42febf49dcb.
• Added: DuckieDai Molarity 1.0.0 calculates moles of solute divided by liters of final solution. Reviewed source SHA-256: fc97f2e47224144e300d273fb015f815d741a8c9f3788f40710cdc71495ba70f.
• Improved: All three DuckieDai program pages explain the device test in plain language and let visitors walk through the duck opening and calculation on a calculator-style browser screen. Browser previews do not run TI-Python or emulate the device.
• Documentation: DuckieDai Final Velocity: DuckieDai's TI-84 Plus CE Python; OS 5.8.3; Python App 5.8.3.0048; sent through TI Connect CE and named PTEST on the calculator. DuckieDai reported that the exact prototype ran successfully, including the duck opening, Enter pause, prompts, and final answer. The listed edge cases were checked on desktop, not reported as calculator tests.
• Documentation: DuckieDai Molarity: DuckieDai's TI-84 Plus CE Python; OS 5.8.3; Python App 5.8.3.0048; sent through TI Connect CE and named CTEST on the calculator. DuckieDai reported that the exact prototype ran successfully, including the duck opening, Enter pause, prompts, and molarity answer. The listed edge cases were checked on desktop, not reported as calculator tests.
• Documentation: DuckieDai Rectangle Area remains at source version 1.0.0 with unchanged download bytes. DuckieDai's TI-84 Plus CE Python; OS 5.8.3; Python App 5.8.3.0048; sent through TI Connect CE and named TEST on the calculator. DuckieDai saw the duck opening, entered a unit and rectangle dimensions, and got the labelled area answer on the calculator.

The reviewed DuckieDai Rectangle Area program now has an interactive, calculator-style browser preview showing its duck opening, prompts, and labelled answer before download.

• Added: Step through the DuckieDai opening, unit, width, and height prompts on the program page, then see the area and squared unit on the simulated screen.
• Improved: Show the program's retry message for invalid dimensions and a restart control; clarify that RECTAREA is a suggested calculator name and visitors may choose another valid, unique name.
• Privacy: Keep preview inputs and results in the browser with no interaction requests or analytics. The preview recreates the reviewed flow but does not execute TI-Python or emulate calculator hardware.
• Documentation: Keep the physical-device review and exact downloadable Python bytes unchanged. Review environment: TI-84 Plus CE Python; OS 5.8.3; Python App 5.8.3.0048; transferred as a .py file through TI Connect CE into RAM; user-selected AppVar name TEST.

When a document cannot be inspected safely, students now receive a specific, privacy-safe explanation and a useful next step instead of one generic validation message.

• Fixed: Explain when a PDF is password-protected and when a Word or Excel file appears password-protected, encrypted, or saved in a legacy Office format.
• Improved: Provide distinct guidance for damaged or mismatched files, macros, missing Office structures, unsafe package paths, compression and expanded-size limits, binary text, and unsupported text encoding.
• Privacy: Keep operational telemetry content-free: the private dashboard still records only the document type and the broad File validation stage, never the filename, document contents, password state, or detailed reason.

• Open the document scanner
• Review the inspection methodology

The source-visible calculator program library launches with its first physically tested DuckieDai program, exact downloads, browser previews, and transfer guidance.

• Added: Publish the Calculator Program Library index, stable program pages, source viewer, immutable versioned downloads, search and filters, and a first-time TI-84 Plus CE Python transfer guide.
• Added: Publish DuckieDai Rectangle Area 1.0.0 as the first program under the MIT License; its reviewed source SHA-256 is 5291290b23032d479d34f740ca41a5a13f96a036636544784054aadfa6478b32.
• Documentation: Record the successful physical-device test on a TI-84 Plus CE Python with OS 5.8.3 and Python App 5.8.3.0048, including TI Connect CE transfer and a user-selected AppVar name.
• Security: Resolve downloads only from validated catalog identities, verify their bytes and digests, reject path and filename manipulation, and never execute downloaded source during rendering.
• Privacy: Keep simulation inputs and source interactions in the browser with no library analytics, accounts, uploads, or user-content transmission.
• Accessibility: Support keyboard use, JavaScript-disabled source and downloads, 320-pixel layouts, 200% zoom, reduced motion, light/dark themes, forced colors, and zero serious or critical Axe findings.

The public Updates page now stays focused on verified releases instead of showing a changeable planning board.

• Fixed: Remove the public Next, Later, and Exploring planning cards so shifting internal priorities are not presented as a dependable schedule.
• Improved: Keep release search, pagination, stable release links, and the chronological release record unchanged.
• Accessibility: Reverify the simplified page across mobile, tablet, desktop, light and dark themes, 200% zoom, keyboard use, and JavaScript-disabled use.
