KoalaDev adab684ed0 perf+fix: debounce seq persistence + role changes, null-clear stale peer state
- server: SET_PEER_ROLE now uses the same per-room 500ms debounce as
  SET_CONTROL_MODE (M-4), preventing a buggy/malicious host from
  thrashing the room's UI with rapid promote/demote bursts.
- server: PEER_STATUS relay treats explicit null as 'clear' for
  tabTitle/mediaTitle/currentTime, so the tab-close heartbeat actually
  zeroes out stale state on other peers instead of being silently
  preserved by the clamp fallback.
- background: _persistLastSeq is now trailing-debounced (500ms),
  cutting storage.session IPC writes from one-per-relayed-event to
  one-per-quiet-window in active rooms.
- locales: add missing TOAST_ID_REGENERATED to all 14 non-English
  locales (was blocking locale coverage test on main).
- test: H-1 force-sync demote test now waits out the debounce window
  to reflect real-world UI timing (a host cannot promote, run a
  force-sync, and demote inside 500ms).

Development Scripts

This directory contains utility scripts for the KoalaSync development workflow.

build-extension.cjs

The primary build tool for KoalaSync. This Node.js script automates two critical tasks:

  1. Protocol Synchronization: Copies the "Single Source of Truth" constants (shared/constants.js) and the domain blacklist (shared/blacklist.js) from the root /shared directory into the extension/shared/ directory.
  2. Content Script Injection: Injects protocol constants directly into content.js using marker-based replacement. This is necessary because content.js executes synchronously and cannot use ES module imports.
  3. Artifact Generation: Compiles the extension into browser-specific bundles for Chrome and Firefox, located in the dist/ directory.

Usage

From the repository root, run:

node scripts/build-extension.cjs

Why this script exists

KoalaSync uses Vanilla JS in the extension to maintain zero runtime dependencies and maximum privacy. Since we don't use a bundler (like Webpack or Vite) inside the extension, this script serves as our lightweight "pre-build" step to ensure that the protocol constants remain synchronized between the extension and the relay server.

Content Injection Markers

The build script uses marker comments in content.js to locate and replace constant blocks:

Marker Pair Injected Value Source
SHARED_EVENTS_INJECT_START / END The full EVENTS object shared/constants.js
SHARED_HEARTBEAT_INJECT_START / END HEARTBEAT_INTERVAL value shared/constants.js

⚠️ Do NOT remove or modify these marker comments in content.js. They are required for the build script to function. If the markers are missing, the build will fail with a clear error message.
