Lineage

Declared at intake, carrying any prior negative result
Relation to prior work
experimental descendant
Note
A0.3 tested the break that DOES re-enter the prior range and trades reversal, and was rejected. A5.07 is its complement: the break that touches back but HOLDS outside, traded as continuation. Declared descendant; carries A0.3's negative prior.

Frozen specification

Snapshotted at intake — not re-read from a live module
Mechanism hypothesis
A breakout that looks failed -- price returns to the compression boundary -- but never closes back inside, traps the fade and continues.
Long rule
range(20) <= P25(trailing 240); a close above the band; within 5 bars price touches back to the band boundary WITHOUT closing inside; then a close above the break extreme: enter LONG next bar open.
Short rule
Mirrored below the band.
Entry trigger
Three-stage, all on closed bars. One signal per compression instance; a close back inside the band cancels.
Earliest executable entry
The OPEN of the next 1-minute bar after the trigger bar closes. Enforced structurally by A5StrategyBase's pending-entry queue, which is drained at the top of the following ingest() -- a rule cannot fill on its own trigger bar.
Initial stop
The deepest retracement extreme reached during the false failure.
Exit
FIXED_2R via the shared TradeTracker, max-hold backstop.
Session restriction
RTH onlyThe compression percentile population is dominated by thin overnight ranges if both sessions are pooled, which would make the compression test fire on liquidity rather than on genuine coiling.
Causality
The compression band is measured on bars strictly before the break, and each later stage is confirmed on a closed bar. Every statistic is computed from closed 1-minute bars up to and including the trigger bar, against trailing (already-observed) history. Entry is deferred to the next bar's open. No same-bar entry.
