MF-01 / DEVELOPMENT RECORD AND PREREGISTRATION WORKSHEET
NOT SUBMITTED. NOT A COMPLETE CONFIRMATORY PREREGISTRATION.

Proposed responsible author: Christopher Hill; confirm actual contributions,
rights, affiliation and any other contributors before submission. Do not omit
someone's qualifying contribution merely to preserve a solo-author narrative.

Development-record summary: We propose to recover conventional external-beam
photon pressure at 2 W intercepted power using an independently calibrated,
owned balance. No measured force dataset exists. Apparatus qualification,
secondary test thresholds and independent review remain incomplete.

Primary estimand: corrected full beam-on minus beam-off force; optical prediction
(1+R-T)P/c in the collinear normal-incidence limit, otherwise a vector ledger.
Require |measured-predicted| <= U(difference) and U <= .15*|prediction| with controls.
Ideal 2 W prediction 13.3425638 nN. Seven-term U=1.626 nN is only a planning budget.

Before confirmatory registration, fill and review:
1. Geometry, serial numbers, intercepted-power definition and calibration records.
2. Sampling/dwell/settling, effective N, stopping rule, ABBA/BAAB schedule.
3. Frozen linearity model, slope/intercept acceptance, covariance and missing data.
4. Measured nuisance transfer functions, exclusion rules and control thresholds.
5. Coverage justification, analysis/code hash and preregistered failure handling.
6. Responsible operator, independent technical disposition, data and release plan.

A time-stamped development registration may document these open questions, but
must not be advertised as a completed confirmatory protocol or a G0 pass. Archive
subsequent changes transparently. OSF's administrative approval is not peer review.
