# zicula-content-decay-kit — free sample

Three real pieces from the full kit, each **trimmed to taste** — enough to judge
the quality, not enough to run a client portfolio on:

- `decay-math-excerpt.mjs` — the decay-detection core from `decay/decay.mjs`
  (the actual product script, ~700 lines): the per-day normalization, the
  20%-threshold + 200-impression noise floor, the full "why did it fall"
  classifier (ranking slipped / seen-not-clicked / demand cooled / mixed) and
  the matching P1–P3 priority + refresh-angle suggestions. Verbatim code — you
  can read every line of the math before you buy. What the excerpt does NOT
  include: the Google OAuth/service-account client, the Search Console API
  calls, the white-label digest + dashboard renderers, demo mode, history,
  webhook, CLI — the other ~570 lines that make it run end to end.
- `playbook-14d-preview.md` — the front half of `PLAYBOOK-14D.md`: why clients
  pay for a weekly decay digest, the copy-paste price framing ($29–99/month
  per client as a care-plan add-on), and Days 1–5 of the 14-day plan. Days
  6–14 (productizing the offer, extending to the whole portfolio, the
  measure-and-decide gate) are summarized in one line each at the end.
- `properties-config-example.json` — the exact shape of `config/properties.json`,
  the one file you must edit: your agency brand (the digest is white-label —
  your name on top), the thresholds you can tune, and how a client property
  is listed. Trimmed to one example client; the full kit ships with two
  placeholder clients and inline guidance.

## What the full kit adds (15 files, ~1.3 MB unzipped)

- `decay.mjs` in full — OAuth JWT login, official Search Console API calls,
  dashboard + per-client white-label digest renderers (print/PDF-ready,
  no vendor name anywhere), deterministic `--demo` mode that runs the whole
  pipeline with no credentials, append-only run history, optional Slack-style
  webhook, CI flag `--fail-on-decay`.
- `SETUP.md` — Google service account → first real scan, ~20 minutes one-time,
  with a symptom/fix troubleshooting table.
- `CUSTOMIZE.md` — brand the digest, tune thresholds, reword the refresh angles.
- `config/properties.json` in full — two placeholder clients and inline
  tuning guidance.
- `cron/` — one-line crontab recipes for any host, plus a ready GitHub Actions
  workflow (free, private repo, no server).
- `PLAYBOOK-14D.md` in full — the 14-day plan that turns the digest into a
  paid weekly deliverable.
- `MANIFEST.md`, `README.md`, `LICENSE.txt` — single-agency commercial license.
- `screenshots/` — five walkthrough renders from the real kit files: the SETUP
  guide, the README quickstart, PLAYBOOK-14D, the all-clients dashboard and a
  white-label weekly digest (from an actual `--demo` run).

Zero npm dependencies, Node 18+. Weekly cadence by design (Search Console data
lags 2–3 days).
