Accessible Inputs Kit: Date Range, Command Palette and Combobox

v2.0 is out. Rebuilt the forecasting views with Claude Opus 5.5 and then spent a week on the empty states nobody screenshots.

Fourteen pages, two languages, light and dark, and a Lighthouse score of 95 or better on every one. Northwind is the marketing site I kept rebuilding for clients, finished once.

Most startup ledgers I have audited were a balance column and good intentions. Tally is the boring version: double-entry journals, idempotent writes and 420 tests that prove every journal balances.

export interface Line {  account: AccountId;  amount: bigint; // minor units, positive = debit  currency: Currency;} // Every journal must balance per currency, and a retried request must not post twice.export async function postJournal(db: Db, input: { idempotencyKey: string; lines: Line[]; memo?: string }) {  for (const [currency, total] of sumByCurrency(input.lines)) {    if (total !== 0n) throw new UnbalancedJournal(currency, total);  } 

Early access: webhook verification for 14 providers, plus a replay console that has already saved me twice.

import { createHmac, timingSafeEqual } from 'node:crypto'; export function verifySignature(secret: string, payload: string, header: string) {  const [timestamp, signature] = parseHeader(header);  if (Date.now() / 1000 - timestamp > 300) return false;   const expected = createHmac('sha256', secret)    .update(`${timestamp}.${payload}`)    .digest('hex');   return timingSafeEqual(Buffer.from(expected), Buffer.from(signature));}

Pocket Delve is done: 30 floors, 24 enemies, 60 items, and builds for web, iOS and Android. Swap the sprites with the reskin guide and it is your game.

Driftline 1.1: six tracks, a track editor and touch controls. Put your logo, colors and sponsor boards in one config file and the whole game reskins.

Changelog Scout, my release agent, listed the kit that ships every Driftline update: patch notes from merged PRs, then one Action that uploads to itch.io and Steam.

Ported to Claude Opus 5.5 and re-ran our eval: 31% fewer escalations. Tagging moved to Gemini 3.8 Flash, so a ticket still costs about a cent.
