#2019 feat(nurture): arm model-usage-without-workflows (BUILDING PRODUCT FEATURES)

Parent: the product-nurture epic. Arms whiteboard flow #3 — BUILDING PRODUCT FEATURES.

Sustained model usage and zero workflow run. These are the operatives who have adopted half the product: they are running methods by hand, repeatedly, which is precisely the shape a workflow exists to replace. The message promotes workflows and shareability.

Qualification

model_no_workflow: ≥3 distinct active days with a command = 'model' invocation in the trailing 30 days, and zero command = 'workflow', subcommand = 'run' invocations ever.

Both terms come from cli_daily, which is already keyed (distinct_id, command, subcommand, day) — this is the cheapest read in the set, and the only one whose grain matches the question exactly.

occurrenceKey: "once". If the pitch does not land the first time, sending it again does not improve it.

Two things to get right

"Ever" means ever, and cli_daily is day-grain from the beginning. Do not bound the workflow-usage term to the same 30-day window as the model term. An operative who ran one workflow eight months ago and stopped is not the audience for "you have never tried workflows" — they are a different (and more interesting) segment, and conflating them makes the copy wrong.

A collective's daemon is not a person. swamp serve on a collective API key ingests under collective:<id>, and a team daemon runs model methods constantly. The grain-level exclusion (#1679) must be present on this read or the flow's largest apparent qualifier is a credential.

Verification

• Fixtures at 2 and 3 active model-days; one with a single workflow run at the far edge of history (must not qualify); one whose activity is entirely under a collective: id (must not appear at all).
• A captured-SQL assertion that the workflow term carries no day floor.
• In production: hand-check the first cohort — for each, zero workflow/run rows in cli_daily across every bound device, for all time.
