Two surfaces, one product story

This marketing host answers SEO and prospects. The tenant desk holds IAM, workspaces, and your artifacts. They share design language — not databases.

Security posture (plain language)

Identity

HTML flows use signed sessions; APIs accept verified Bearer tokens. Same user, two transport idioms.

Public JSON

Marketing demos and health checks are allowlisted. Arbitrary /api/* stays behind the gate.

Ops

Deploy hooks watch /api/ready; super-admins can unlock full readiness JSON for runbooks.

Extensibility contract

LayerRule
ToolsPrefer GET-query tools so URLs stay shareable and audit-friendly.
Marketing APIWhitelist tool IDs + cap payload size + per-IP rate limits.
NavigationNew labs ship as routes — the command palette indexes discoverability.

Three-minute mental model

RMFU is one surface for reading (brief + pulse), remembering (library + drills), and stress-testing (risk, macro, scenarios). Sign in to reach your tenant desk; this public site is the story, not the datastore.

Open the full guided tour → (recommended instead of this short blurb).

Use Open desk when you already have access — you will authenticate at the gate like any other protected route.

Live calculators vs. marketing

After sign-in, /tools hosts shareable one-page calculators (NPV, payback, Kelly, and more). This public tools hub explains what exists for crawlers and prospects.

Why drills matter

Bookmarks decay. RMFU uses short, spaced repetitions so vocabulary and frameworks stay retrievable when you are in front of a committee or a live tape — not only when you are reading alone.

Nudge inputs

Edit fields, then Apply & refresh (or use ↻ on the card). Same payload as the public demo API.

"""Operator pocket tools — small pure functions used by /tools.

Each function returns a dict with the inputs echoed back, the result, and a
short interpretation sentence (in casual exec tone).
