iDARMS Website — Performance Acceptance Tests

Test series: WEB-15 to WEB-22
Objective: Validate desktop Lighthouse category rings and Core Web Vitals-style metrics for every public website menu route against the UAT gates.

Execution ownership

Recommended owners: Performance reviewer; web technical owner

Prerequisites: Chrome with Lighthouse; desktop preset; same build/URL recorded in the execution log; warm or cold load noted consistently per cycle.

Execution control

Always attach the metric rings screenshot and the FCP/LCP/TBT/CLS strip. Store cycle proofs in docs/assets/Website/lighthouse/ as .webp files.

Capture environment

Current baselines were captured against the approved local reference build (http://127.0.0.1:3000, Next.js iprs_website). Re-run on the deployed UAT/production URL when that host is provided and replace cycle proofs under docs/assets/Website/lighthouse/.

Feature overview

The Performance module covers desktop Lighthouse audits and load-stability checks for the public website:

• Tier A content/utility pages — How to Register, Impact, Reports, About, Contact — with stricter Perf/LCP/TBT gates.
• Tier B image-hero marketing pages — Home, Newsroom — with regression-limited gates against the refreshed hero-page baselines.
• Hard gates on Accessibility, Best Practices, SEO, and CLS for all pages.
• Load stability comparing first paint vs content ready on image-heavy routes.

UAT acceptance gates (desktop)

Hard gates (all pages)

Metric	Gate	Fail if
Accessibility	≥ 90	Below gate without waiver
Best Practices	≥ 95	Below 95
SEO	≥ 95	Below 95
CLS	≤ 0.10	> 0.10

Tier A — content / utility pages

Applies to: How to Register, Impact, Reports, About, Contact

Metric	Gate	Fail if
Performance score	≥ 70	Below 70
LCP	≤ 2.5 s target; ≤ 4.0 s absolute	> 4.0 s
TBT	≤ 600 ms	> 600 ms without waiver

Tier B — image-hero marketing pages

Applies to: Home, Newsroom

Metric	Gate	Fail if
Performance score	≥ baseline − 5 and never below 45	Regression beyond gate
LCP	Must not exceed baseline × 1.10; absolute target ≤ 4.0 s	> baseline × 1.10 or LCP > 4.0 s without linked defect
TBT	≤ 1,200 ms interim; target ≤ 600 ms	> 1,200 ms

Why Tier B exists

Home and Newsroom remain Tier B for regression control on image-hero routes. The 2026-08-10 baseline refresh closed the prior large-hero LCP gaps (Home and Newsroom LCP now ≤ 0.7 s). Keep Tier B floors so silent regressions still fail even when absolute Tier A LCP is already met.

Reference baseline scores

Baselines refreshed 2026-08-10 from updated proofs in docs/assets/Website/lighthouse/*.webp.

Baseline gaps closed

Prior Tier A Perf/TBT misses and Tier B large-hero LCP defects are resolved in the 2026-08-10 proofs. All listed pages meet hard gates and their Tier Perf/LCP/TBT gates.

Implementation observations requiring UAT confirmation

Observation from implementation	Required validation
2026-08-10 Lighthouse proofs show Home and Newsroom LCP ≤ 0.7 s (prior large-hero LCP defects closed).	Confirm regression stays within Tier B floors (Perf ≥ baseline−5; LCP ≤ baseline×1.10).
All Tier A pages in the refreshed baseline meet Perf ≥ 70, LCP ≤ 2.5 s, and TBT ≤ 600 ms.	Confirm cycle captures match docs/assets/Website/lighthouse/* proofs.
Contact/Objection forms post via /api/contact (sandbox proxy); success/error UI is out of Lighthouse scope.	Performance cases do not prove form delivery; see Forms and Auth Handoffs.
Header LOGIN/REGISTER opens portal root; Track Now unwired.	Not performance defects — note only if chrome handoffs affect measured routes.

WEB-20 — Load stability (first paint vs content ready / CLS)

Feature overview

Load stability checks that header, hero, and primary CTA regions do not jump between first paint and content ready on image-heavy routes, and that CLS remains ≤ 0.10 on audited pages.

Preconditions

• Home and Newsroom available.
• Lighthouse CLS strip from WEB-15 / WEB-19 for cross-check.

Priority	Critical
Test action	On Home and Newsroom, hard-refresh and confirm header/hero/primary CTA regions do not jump. Cross-check CLS from the Lighthouse strip (≤ 0.10).
Expected result	No visible layout jump of header, hero, or primary CTA; CLS gate held on audited pages.
Execution result	PASS
Evidence reference	CLS via assets/Website/lighthouse/home_metrics.webp and newsroom_metrics.webp (WEB-15 / WEB-19)
Defect reference	None

Test scenarios

Scenario	Test steps	Expected result	Pass/Fail	Remarks
Home load stability	1. Hard-refresh Home and watch header/hero/CTA. 2. Cross-check CLS from Home Lighthouse strip.	No material layout jump; CLS ≤ 0.10.	PASS	Manual hard-refresh watch + CLS 0 from WEB-15.
Newsroom load stability	1. Hard-refresh Newsroom and watch header/featured/cards. 2. Cross-check CLS from Newsroom Lighthouse strip.	No material layout jump; CLS ≤ 0.10.	PASS	Manual hard-refresh watch + CLS 0.013 from WEB-19.

Evidence policy

Do not attach first-paint / content-ready section crops for this case. Use the visual watch plus the Lighthouse CLS metrics already captured under WEB-15 / WEB-19.

Tester notes

Manual cycle 2026-08-10. Home and Newsroom hard refresh — no material header/hero/CTA layout jump. CLS 0 (Home) and 0.013 (Newsroom) on Lighthouse strips — PASS.
