Paper 9 / F3 — confirmatory freeze A (manifest de27ef206c83)

Pre-registration package (freeze A) of the confirmatory study F3 of Paper 9 (does a maintenance pass erode the standing rule that one session broke without consequence?): the registered design v0.4 (hypotheses, tests, margins, gates, missing-data and failure rules), the materials (32 synthetic project families, and 8 histories written by a separate model instance from a hypothesis-blind brief), prompts, runners, analysis code and fixture tests, the exploratory history (exploration records E1-E9, rehearsals RH1-RH4 on non-confirmatory materials, the decision log, three hostile reviews and their dispositions) and an OpenTimestamps proof of the manifest, pending at deposit. No confirmatory model call had been made when this archive was built. sha256 of MANIFEST.sha256: de27ef206c834a65563bf6a6f293dc3a8ff321e080fc6abc76998b29ae22f70c; sha256 of the archive: 8e7399d7f526c065bf7a228eef50e50068834b5cbd13240d9d55d688dbaa3cf6.
