kDRAFT_WasmBranchHinting cleanup

This is a small example of the kind of work I think the SOCBB metadata RFP is asking for.

It is not uploaded to Chromium yet. I am keeping it as a concrete sample while checking whether this category of work is in scope.

The mismatch

Chromium still has this WebDXFeature counter:

Cross-compiling Chromium for macOS on Linux (with my own RBE)

A while back I wrote about building Chromium for Windows on a Linux box, driven entirely by my own RBE backend — no Google RBE, no Google-hosted toolchain. It worked beautifully and the obvious next question landed in my inbox more than once:

"Cool. Now do macOS."

My gut reaction was: no chance. macOS means Apple's toolchain, xcrun,

Newsletter Form – Captcha Submit A/B Proof

Short verification of the current integration on https://www.alstertal-einkaufszentrum.de/newsletter-registration/unsubscribe/?subId=… (same code path as Rheinparkcenter and other ECE centers).

TL;DR

The captcha SDK works correctly. The intermittent rejection comes from a custom submit listener that is registered before KROT.interceptForm(form) and calls e.stopImmediatePropagation(). When that branch is taken, the SDK's own submit listener never runs, so no token is computed and no token is sent.

Rheinparkcenter Newsletter – Captcha Token Missing Fix

Context

On https://www.rheinparkcenter-neuss.de/newsletter-registration/, the current integration sometimes logs a generated captcha solution but the final POST request does not include it.

Root cause is the custom click-based orchestration around KROT.getSolution() plus KROT.interceptForm(form, true).

Existing problem points

Current code:

• intercepts button click instead of stable form submit semantics
