# Dragon Followthrough Mid Exit Review

## Scope
- focus: shadow-only exit treatment for `mid_zone_very_weak_b1` followthrough reentry
- objective: test whether the current `knife_take_profit_2_glued` path is clipping a valid repaired trend too early

## Branch Summary
- base same_close avg `3.42%` | PF `5.11` | comp `1424.12%`
- mid_probe same_close avg `3.38%` | PF `5.09` | comp `1420.41%`
- mid_exit_probe same_close avg `3.45%` | PF `5.15` | comp `1460.02%`
- base next_open avg `3.31%` | PF `4.73` | comp `1295.54%`

## Trade Path Diff Vs Mid Probe
- `removed_vs_mid_probe` | `2020-12-01` -> `2020-12-09` | `glued_followthrough_reentry_buy:confirmed_mid_zone_very_weak_b1` -> `knife_take_profit_2_glued` | return `-0.24%`
- `removed_vs_mid_probe` | `2020-12-15` -> `2021-02-19` | `glued_buy` -> `high_regime_confirmed_exit:kdj_sell` | return `23.73%`
- `added_vs_mid_probe` | `2020-12-01` -> `2021-02-19` | `glued_followthrough_reentry_buy:confirmed_mid_zone_very_weak_b1` -> `high_regime_confirmed_exit:kdj_sell` | return `26.65%`

## Judgment
- The narrow mid-exit probe is materially better than the original mid probe on the only confirmed followthrough sample.
- It converts the repaired-trend trade from a small loss into a long hold ending with a high-regime exit.
- It also improves branch-level compounded return versus both the original mid probe and the current RC1 branch in this replay.
- This is still a one-path result, so it should remain shadow-only for now, but it is strong enough to keep under daily observation.
