# v17g effect-blind reverse-closure qualification

Status: `v17g_reverse_closed_length5_move_qualified`.

## Purpose and goal

Purpose `purpose://validation`: determine whether the exact v17f raw generator can be made reverse-closed by a deterministic support filter without changing accepted dynamics. The frozen goal requires 24,576/24,576 raw-generation parity, exact identity of all 11 filtered auxiliaries, accepted-transition and endpoint parity 24/24, retained reverse support 24/24, representation 12/12, movement 24/24 and resource 24/24.

## Law change

The batch size, length-5 constructor, 20,000-state bounded witness law, old-kernel mixture, starts, seeds and 1024-step budget are unchanged. A raw length-5 auxiliary whose explicitly mapped reverse auxiliary is unsupported under that same bounded law becomes a self-loop before valid-proposal accounting. No extra random draw is made. Retained auxiliary probabilities and the lazy Metropolis ratio are unchanged.

## Finite evidence

Across 24 chains, `11` raw auxiliaries were filtered. Minimum retained valid proposals were `130`, minimum accepted length-5 cycles `7`, and maximum runtime `20.456393` seconds.

## Interpretation boundary

This gate changes the declared proposal support and valid-yield accounting, but deliberately reproduces every accepted v17f transition. A pass is probability-law and instrumentation qualification, not new dynamical evidence, connectivity, convergence, mixing, a source effect or physics.
