- Stuck detection after clicking Next: if heading+progress unchanged 2x, exit with 'stuck' status instead of looping forever - Select dropdowns: treat "Select an option" as unfilled (LinkedIn's placeholder has a truthy value that was skipping the fill logic) - Continue button fallback: detect draft "Continue" span via apply URL pattern when Easy Apply button not found Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

/**
|
||
* easy_apply.mjs — LinkedIn Easy Apply handler
|
||
* Handles the LinkedIn Easy Apply modal flow
|
||
*
|
||
* IMPORTANT: LinkedIn renders the Easy Apply modal inside shadow DOM.
|
||
* This means document.querySelector() inside evaluate() CANNOT find it.
|
||
* Playwright's page.$() pierces shadow DOM, so we use ElementHandle-based
|
||
* operations throughout — never document.querySelector for the modal.
|
||
*
|
||
* Button detection strategy: LinkedIn frequently changes aria-labels and button
|
||
* structure. We use multiple fallback strategies:
|
||
* 1. CSS selector via page.$() (pierces shadow DOM)
|
||
* 2. ElementHandle.evaluate() for text matching (runs on already-found elements)
|
||
*
|
||
* Modal flow: Easy Apply → [fill → Next] × N → Review → Submit application
|
||
* Check order per step: Next → Review → Submit (only submit when no forward nav exists)
