Stop ignoring screen size when scrolled is ignored

[simpleanalytics-agent]

Summary

Fixes #126

The screen size check used the sc prefix, which also matches scrolled. It now uses scre, next to the existing scro prefix for scrolled, so each metric can be ignored on its own. screensize, screen, screensizes and screen-size still ignore the screen size. Only the undocumented sc and scr shorthands no longer do.

Only src/ changes. dist/ is rebuilt separately, as with previous PRs.

Security implications

No security impact

Testing

• pnpm run build, pnpm run typecheck, pnpm run test:deploy (12/12) and pnpm run test:matrix (11 passing) all succeed locally. BrowserStack tests were not run (no credentials in this environment).
• Ran the built latest.js in headless Chrome and captured the page view and beacon payloads:

data-ignore-metrics	Fields dropped before	Fields dropped after
scrolled	scrolled, screen_width, screen_height	scrolled
timeonpage,scrolled	duration, scrolled, page_id, screen_width, screen_height	duration, scrolled, page_id
screensize / screen	screen_width, screen_height	screen_width, screen_height

Every other documented value still drops only its own field.

📝 Walkthrough

The screen-size collection check now uses the scre metric key. When screen exists and scre is enabled, the script records screen width and height.

Changes: Screen-size metric collection

Layer / File(s)	Summary
Screen-size metric check src/default.js	The script checks scre instead of sc before recording screen dimensions when screen exists.

Full details: Linked Issues check

Explanation

Issue #126 requires scrolled to exclude only scroll data. The whole-PR diff changes the screen-size check from collectMetricByString("sc") to collectMetricByString("scre"). The existing collectMetricByString reads both sa_settings.ignoreMetrics and data-ignore-metrics, so scrolled no longer matches the screen-size prefix while documented screen-size values continue to match it. The PR reports build, typecheck, deployment, matrix, and headless-browser checks.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff contains one focused change in src/default.js. It changes only the metric prefix used for screen-size collection. The change directly implements issue #126 and does not show unrelated production changes.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 1 files.

Regenerate the dist/ outputs from src/default.js.

The PR changes only src/default.js, but dist/latest/latest.dev.js, dist/latest/custom/latest.dev.js, and dist/latest/cloudflare.js still call collectMetricByString("sc"). Rebuild every output mapped from src/default.js in compile.js and include the generated changes.

SDLC label: change: needs review because The fix changes the scope of the ignore-metrics privacy control: sites configured with data-ignore-metrics="scrolled" were also suppressing screen size and will now start collecting and transmitting visitor screen_width/screen_height.

[simpleanalytics-agent]

Re CodeRabbit "Regenerate the dist/ outputs": not done on purpose. This repo commits only src/ in PRs and rebuilds dist/ in a separate commit after merging (see PR #91 / a87e9e0, which only touches src/, followed by c14b694 "Run npm run build"). I ran pnpm run build locally to test the built latest.js in headless Chrome (results in the PR description), then reverted dist/.

The failed build check was a BrowserStack session error on one device ("WebDriverError: Session not started or terminated", 19 passing / 1 failing), unrelated to this change. I re-ran the failed job.
