The Matters Experiment

oxexp-matters · the rix record’s follow-on

The gate — acceptance

The six vectors (I + S1..S5) at generation 1, built and NOT frozen (built ≠ frozen; the spec FREEZE with digests pinned + unknowing statements printed is MTX-P0’s sealed act); the ledgers empty; the a-priori cited, never re-derived.

The DRY calibration battery — machinery verification (non-sealed)

The five text-pinned faces on the primality ground, re-read through this experiment’s own code: 1024 / 2560 / 5120 = {000, 110} (the persisted origin-mark bit at all three collision faces) and 2048 / 3072 = ∅. The rix BI-2 precedent: a DRY battery is not a read. The sealed MTX-P1 ran at A1 and landed 22/22 EXACT over the full twenty-two-cell battery — the instrument GROUNDED.

The probe cards — MTX-P0..P5

The sealed probe ladder (§6): P0 the encodings frozen · P1 the calibration re-witness · P2 the controls (the trivial-quiet risk named) · P3 the prediction reads (cards: claim + exact identity + kill condition) · P4 the folds (LINEAR vs STRUCTURAL; match or refusal) · P5 the assembly. SEALED per attempt (the default read = the latest, MTX-A6 against c89431c; MTX-A5 against a731aec; MTX-A4 against f8fd71b; MTX-A3 against c47ab3b; MTX-A2 against 04320aa; MTX-A1 against 4a7dddc); UNSEALED where no seal has committed — seal-before-read. {"live": true} re-verifies (the policy batteries take minutes).

The external anchor

The attempt dataset to the immutable EXTERNAL record (mldata CKAN when configured; the dummy-node fallback otherwise). The anchor dataset is created by the operator’s first publish act; rows exist only once sealed attempts do.
