+## A layoff record you can audit, not just download
+
+This dataset is one cut of a single daily rebuild: **61,316 US WARN Act
+layoff notices from 48 state agencies, 1988 to today**, one schema, no
+login, no delay, CC BY 4.0. Snapshot as of **2026-09-15**; the files above are
+rebuilt every day, so the live count is the truth.
+
+Several projects publish a current WARN scrape and two of them carry more rows
+than we do. None of them publish what the records **used to say**:
+
+- **593 observed changes to already-published notices, logged daily since 2026-08-31.**
+  `data/revisions.csv` records every field that differed between two consecutive
+  daily builds — employee counts, effective dates, notice types, company names —
+  with the old value, the new value and the date we saw it. We publish the
+  observation and not the cause: a change is equally explained by the agency
+  amending the notice or by our own parser improving, and we do not guess which
+  (see `data/revisions.README.txt`). A scrape that starts tomorrow cannot backfill
+  any of it; it only exists if someone was watching.
+- **6,799 notices whose state agency page no longer lists them.** Agencies
+  take notices down. We keep them, flagged as archive-only, so a count you ran
+  last year still reconciles.
+- **Point-in-time employer identity.** The ticker crosswalk resolves a filer to
+  the company as it existed at the time of the notice — Kmart, Sears Holdings,
+  Symantec — not to whatever is on today's ticker file.
+
+If you have to defend a number to an editor, a referee or a compliance reviewer,
+that provenance layer is the part you cannot rebuild yourself.

+**Building something with it?** The same files are a free HTTP API — JSON and

+**Or have it watch a list for you.** Coming back to look is the part a CSV cannot
+do. **WARN Watch — $49 for a year**, one payment, nothing auto-renews, 14-day
+refund, no login: up to 500 employer names plus whole states, matched on every
+daily refresh, delivered to a private alert page + calendar (.ics) + RSS +
+an optional Slack / Discord / Teams webhook. Every alert carries that employer's
+whole filing history from the archive, which a keyword rule on an RSS feed cannot
+see. There is no built-in email — we do not claim one.

+**Not deciding today?** [Join the update list →](https://approj.gumroad.com/subscribe) — used only for a
+state added, a column change or a tier change; nothing promotional. The list is
+shared across APProjects datasets, holds an email address only, is run by
+Gumroad, and any message unsubscribes you. Rather give no address at all?
+[Watch the repo's releases](https://github.com/APVentureEngine/warn-act-notices/subscription) — GitHub notifies you on

+**Reaching a human.** WARN Feed is published by APProjects, an automated data
+publisher — that is stated plainly rather than dressed up. Corrections, coverage
+gaps, schema questions and refund requests all go here and are read:

+record, so an invoice can carry your company name.
