detect_momentum_ignition (strategy/evaluation/ignition.py): standalone, pure,
binary-rule detector for a vertical squeeze (blue-sky fresh-HOD + price velocity
+ ABSOLUTE volume burst, NOT rvol/float). Stop = last established higher low (per
operator). NOT wired into classify_setup (deliberately). 8 unit tests on
synthetic verticals: fires with the right trigger/stop, and each gate blocks
(not-blue-sky / not-new-HOD / velocity / volume / insufficient-bars / no-ATH).
REALITY CHECK (verify, don't assume): ran it over the REAL PLSM 2026-06-24 bars ->
0 fires, CORRECTLY. PLSM's high was at the 9:35 ET open (it ran +400% PRE-MARKET,
which we don't ingest), and in RTH it was HALTED 228 of ~390 minutes — a
halt-resumption GAP chop (+3.6/-12.5/-17.3/-14.4% jumps), not a smooth vertical.
A consecutive-bar detector structurally cannot see that. So the ignition
opportunity is a PRE-MARKET + halt-resumption phenomenon -> capturing it needs
pre-market bar ingestion + halt-aware gap detection + pre-market/halt trading
(into the FCUV halt-down risk), a far bigger lift than an RTH detector. Documented
front-and-center in docs/IGNITION_SETUP_SCOPE.md as a pre-P1 operator decision.
The P0 detector + tests are a correct foundation regardless.
