invoker audit

catalog of JavaScript in this codebase that platform features could replace. scanned 2026-04-10. the browser is the framework.

every useState that manages a boolean toggle is a question the platform already answered. popover, dialog, details, command/commandfor — the specs shipped. the codebase has not caught up.

platform features

these are the specifications that already shipped or are shipping. each one kills a category of JavaScript.

findings

components where JS toggle/modal/dropdown patterns could be replaced by platform features. sorted by occurrence count. not all are trivially replaceable — some manage complex state that goes beyond show/hide. the audit flags candidates, not mandates.

hospice discharge papers

173 handlers weighed for burial. 396.6 KB of deletable JS across 10 terminal and 163 palliative files. 0.10g CO2 per page view — the electricity to run code that the platform already does.

terminal: JS is entirely replaceable by platform features. delete it. palliative: partial replacement possible — toggle logic dies, complex state lives. active: JS is load-bearing. the platform cannot replace it yet.

CO2 estimate: SWD v4 model, ~0.26g/MB transferred. global average grid intensity. methodology is contested — these are not measurements, they are estimates with disclosed assumptions. the bytes are real. the carbon is modeled.

methodology

this page scans source files at build time using regex pattern matching. it counts occurrences of onClick, useState, and toggle/modal/dropdown patterns, then flags components where platform features could plausibly replace JS.

limitations: regex cannot understand intent. a useState managing form validation is not the same as a useState managing a dropdown. the "replaceable" count is an upper bound, not a precise measure. some components legitimately need JS for complex interactive behavior that no platform feature addresses.

the estimated savable bytes is conservative — 200 bytes per component of toggle logic. real savings depend on how much supporting code (event handlers, state management, conditional rendering) could be removed alongside the toggle.

162 components flagged. 10 terminal — JS the platform already replaced. 396.6 KB deletable. 0.10g CO2 per view, compounding with every visitor. the browser ships features faster than frameworks adopt them. the gap between the platform and the code is measured here, weighed, and given discharge papers.
