Does yesterday's high or low work on RTY? Eighteen years, tested

==============================================================
THINRIDGE ENGINE REPORT  -  SCORED UNDER PROTOCOL v1.1
==============================================================

SCOPE: Scored under Protocol v1.1 on FirstRate 1-min unadjusted via Thinridge engine. Intake testimony: NOT received (rule tested as locked). Contamination map sworn: no (seen era as declared or by archive date). Human review of reconciliation residue: NO.

1. THE RULE AS LOCKED
   family      : D - Yesterday's high or low
   as you locked it:
     Yesterday's high or low, at the settings the door shows before anyone touches them (SHELF-01 v1.1): excursion 0.1; sustain 10; hold 60; window 0930-1130; mode fade; sides Both
     seen era from 2023, the split the six teardowns were scored on
   as the engine read it:
   exit model  : time only
   filter      : none
   lineage     : #1
   bars        : one-minute (every signal, fill and exit is on the one-minute series)
   entries     : one trade a day, the first qualifying signal in the window
   history     : 18.6 years, seen era = 2023 onward (declared by submitter, not sworn)
               : trades dated 2023 or later are the seen era; trades before 2023 are the unseen era, and the unseen era decides the verdict

2. VERDICT
   SCORE   : 39 / 100
   VERDICT : REJECTED
   CRATERS : pillar(s) below 50%: II, V
   Pillars : I=5  II=0  III=16  IV=8  V=0  VI=10

3. RESULT
   Trades 1390   Net $4,382.00   Per trade $3.15
   Seen era (2023+): 290 trades, -$2,578.00

   Exits by type: time 1390

4. THE NULL (random-side twins, 5000 seeds)
   Full window  p = 0.0514  (257 / 5000)
   Unseen era   p = 0.0338  (169 / 5000)   <- governs
   Lineage-adjusted p (variant #1) = 0.0338

5. ERA CONSISTENCY (unseen calendar years as windows)

8. SENSITIVITY (+-10% on primary trigger)
   Plateau retention 68%   Sign flip no   Parameters 5

9. LIVABILITY (no points; could a person have held this?)
   Longest stretch without a new equity high: 47 months (ending 2026-08)
   Rolling 12-month windows negative: 47% of 213   Worst 12 months: -$6,215.00 (ending 2023-09)

12. THE AUTOPSY (where the money came from and went; the rule as it ran, no new try)
   Exits: time 1390, $4,382.00
   On the books, unseen era (net $6,960.00): 10:00 $6,112.80  11:00 $9,314.40  12:00 $7,395.00  13:00 $6,960.00  14:00 $6,960.00  15:00 $6,960.00
   By 12:00 the books held $7,395.00 against $6,960.00 at the close; the afternoon gave back $435.00
   Eras: unseen $6,960.00, seen -$2,578.00; largest unseen year 2022 = 47% of the unseen net
   Plateau: 68% retained on a 10% nudge; sign flip no
   Drought: 47 months without a new high (ending 2026-08); median year $269.60; years of median to recoup 41.3

   The money was on the books by noon: $7,395.00 at 12:00 against $6,960.00 at the close; the afternoon gave back $435.00. Longest wait for a new equity high: 47 months, median year $269.60.
   The one next run, if you want it: the clock exit at 12:00, as lineage #2. Prediction on file: within 20% of the unseen net with the afternoon's give-back removed; more than the whole unseen net was on the books by then. Three such runs at most, then the verdict stands.

13. IF YOU TRADE THIS BY EYE
   This rule's money was on the books by noon and the afternoon gave some of it back; taken by hand, the morning was the trade.
   That is what the record says about the rule as written. It is not what next year says.

WHAT THIS CANNOT TELL YOU: the score assumes this rule walked in
once (see lineage) and that your development did not touch the
unseen era. Neither was sworn. A Thinridge audit exists to take
that testimony. Not investment advice. No guarantee of future
results. Statistical analysis of a mechanical rule as submitted.
