# C932–C952 checkpoint

This is a frozen 21-action prefix of the authorized C932–C1131, 200-action research cycle. It is not a completed cycle. The journal contains exactly C932 through C952, and all 44 source snapshots, the pinned C931 predecessor, the research helper and the independent verifier are included.

C952 corrects the C949–C950 continuation premise: retain the original 1400 tail (=1406−6), derive its inverse 4100 and gain 2700, and then obtain 14726 from 12026. The regular trunk's equal numeral 2700 is not the source of that continuation gain. Read the historical C949–C950 claims subject to this correction and the independent review in prep/review_951.md.

Run `python3 evidence/verify.py --through 952` from any directory to replay this prefix without research writes. Add `--require-current-sources` only where all original source paths are available. Absolute SOURCE_BINDINGS preserve source identity; the included snapshot hashes support replay when originals are absent. The verifier's default final gate requires all 200 actions and will correctly fail on this checkpoint. Do not run numbered step scripts as verification: those import the journal writer.

The checkpoint was frozen from a live cycle that had advanced beyond C952. The journal is restricted to its first 21 unchanged records, later numbered scripts are excluded, and model files are restricted to artifact bindings in those 21 records. Unnumbered prep work is included as preparation, not counted as completed actions. Generated cache files and any pending record are excluded. Every payload except the manifest itself is covered by MANIFEST.sha256.
