# Chamber Execution Guide — UNNS Gravity Bridge v0.1

## Stop condition

The real SPARC corpus and chamber inputs are prepared, but **neither chamber
has been run**. Do not begin chamber execution until the frozen protocol and
data-preparation report are accepted.

## Required pre-run validation

From the project root:

```
python validation/validate_sparc_preparation.py
python validation/validate_ladders.py
```

Both must pass. Confirm:

- 175 paired chamber inputs exist;
- 121 galaxies appear in `ladders/PRIMARY_INPUT_LIST.txt`;
- every chamber pair contains exactly the same values;
- no interpolation was used;
- no prior chamber export is mixed into the run.

## STRUC-I v1.0.4 — future execution

Open `canonical/chamber_struc_i_v1_0_4.html` and use:

- MAX LADDER SIZE: `2000`
- MC RUNS: `2000`
- κ STEPS: `40`
- κ MIN: `0.01`
- κ MAX: `1.0`
- DATASET FAMILY: `SPARC_UNNS_GRAVITY_BRIDGE_v0_1`
- DATASET CLASS: `observed_baryonic_acceleration_ladder`

Run the PRIMARY list first. The chamber accepts up to six CSV files per
batch. Complete five independent repeats and export both JSON and CSV after
each batch.

Store future outputs only under:

```
chambers/exports/struc_i/repeat_01/
...
chambers/exports/struc_i/repeat_05/
```

## STRUC-PERC-I v2.5.0 — future execution

Open `canonical/struc_perc_i_v2_5_0.html` and use:

- κ GRID POINTS: `40`
- κ MIN: `0.01`
- κ MAX: `1.0`
- DOMAIN ADAPTER: `Generic`
- downsampling: forbidden

Run the PRIMARY list first. For registered signatures, use each galaxy's
full dataset export, not only the minimal batch summary.

Store future outputs only under:

```
chambers/exports/struc_perc_i/
```

Reject runs that are partial, approximate, downsampled, or use different
settings.

## Interpretation boundary

Numerically equal κ values in the two chambers do not represent the same
scale. STRUC-I uses median-gap scaling; STRUC-PERC-I uses IQR scaling with a
median fallback.

No chamber result may be interpreted until export validation and signature
assembly have been completed.

## v0.3 project interpretation

This document belongs to the external transfer experiment. Numerical, technical, protocol, or provenance content above is preserved. The transfer result tests one static global architecture: it does not negate the galaxy-specific structural information carried by the curves. Complete curves retain identity, and ρ is the leading channel for local or regime-conditioned follow-up.
