Methodology

How we source, verify, and refresh the content on this site. Every claim is traceable; every state row carries a last-verified date.

Primary-source policy

Federal statutes. Linked to Cornell LII (law.cornell.edu/uscode/). When a statute has been amended, we show the current text and footnote the amending public law (e.g. Lilly Ledbetter Fair Pay Act 2009 amending Title VII §706(e)).
Federal regulations. 29 CFR Part 1601 (general charge procedure) and Part 1614 (federal-sector procedure) are sourced from Cornell LII and eCFR. We avoid lex-aggregator or law-firm summaries.
Supreme Court decisions. Linked to supreme.justia.com with the official U.S. Reports citation. We do not cite "as discussed in" sources for foundational cases like Morgan (2002) or Ledbetter (2007).
State FEPA designation. 29 CFR §1601.74 is the canonical EEOC-designated agency list. State statutes for FEPA operating law are sourced from each state's own statutory site or Cornell LII's state code mirror where available.
State filing windows. Per-state internal deadlines are sourced from each agency's published procedural rules, not from FAQ pages or law-firm summaries. Where a state's published deadline is uncertain or unverified, the state-deadline field renders as "not separately recorded" rather than guessing.

Review cycle

All state rows and federal-statute references are reviewed on a quarterly schedule. We additionally re-audit on triggering events:

Statutory amendments (state or federal) affecting filing deadlines
State agency restructures or renames
Federal-circuit decisions that change Morgan doctrine
Supreme Court grants of certiorari on EEOC procedural questions
Material EEOC guidance updates

The last-verified date on each state page is the date that row was most recently audited against primary sources.

What the decoder does (and does not) compute

What it does

Federal 180/300 day calendar arithmetic by state
State filing window where the state's window is verified
Federal-employee 45-day branch under 29 CFR §1614.105
EPA direct-court branch with 2/3-year SOL
§1981 direct-court branch with 4-year SOL
Employer-size threshold gates (Title VII 15+, ADEA 20+)
Georgia private-sector and North Carolina non-age 180 default

What it does not do

Tolling for military service, mental incapacity, fraudulent concealment
Non-trivial continuing-violation patterns (multi-act + hostile-environment hybrids)
OFCCP channel-of-first-resort selection
State-court tort SOL calculations (parallel claims)
Substitute for licensed-attorney case-specific advice

Privacy by design

The decoder runs entirely client-side. We never log the incident date you enter. The only analytics we record are categorical: state abbreviation, statute route, employer-type bucket, employer-size bucket, and the decoder output's determination class. We never log free-text inputs and we never echo decoder inputs in URL query strings.
