Cold email (page 16) is one road to ICP1. These are the roads that cost no send and reach the open-hardware / DIY sub-segment where you cannot buy a list. Run them in the background, weekly, while the message test runs.
Paid spend limit: $0 unless the operator approves it in writing. Every channel on this page is free.
Where the DIY holography people already are: image.sc, the napari Zulip, and r/microscopy / r/opticsprint-style communities (the accounts and rules are on page 08). Answer reconstruction questions as a helpful person. Do not pitch. If your answer is genuinely useful, your profile and signature do the work. First posts are operator-gated — read page 08.
Artifact: a logged, useful answer per week, with its permalink.
The Watcher is a script that queries public scholarly sources (OpenAlex works and theses) for new authors doing digital holography and writes them into the prospect-log format, so your list refreshes itself. Run it monthly, review every row by hand, and claim rows per the one-owner rule before any contact. Never run it against live sources on a whim — it is a monthly, reviewed job, and rows it produces are leads to verify, not people to email on sight.
Artifact: a dated CSV of new candidate rows, reviewed, merged into the log. To turn a reviewed row into a single, specific email, follow page 35.
Every reconstruction result carries a ready-to-paste methods sentence (the "citation line"): it names the service version, the settings fingerprint, and the provenance ID, so a researcher can cite exactly how a figure was produced. When a lab uses it in a paper or preprint, that is both a reference and a durable, honest piece of marketing. Point trial users to it in the result.
Artifact: a citation line appearing in a prospect's methods section.
A short, public, plain-language note on what a provenance record is and why re-computable methods matter — capability, not numbers. It links back to the service. Keep every claim inside the boundary.
Artifact: the note published on the site; its URL logged.
NOT YET APPROVED — do not offer until page 09 lists it. The idea: the first three labs in a sub-field get an extended free engagement in exchange for being named reference users. The terms (how long, what they commit to) are an operator decision that has not been made. Do not describe it to any prospect, quote it, or imply it exists. It lives here only so the mechanism is written down for when the operator rules on it.
The "second opinion" is: a lab runs our validation harness on data with an exactly known answer and sees for themselves how a reconstruction scores — their verdict, not our claim. The harness builds a test hologram with a known ground truth, runs a reconstruction (ours or theirs), and reports the score. When it is packaged as an installable tool, the install step is operator-gated (a publish, like page 01) — do not publish it yourself. Until then, describe it as a capability a trial user can ask for; do not quote any score it produces as a marketing number.
Artifact: a lab running the harness and reporting its own result back.
