Day 15 — the best up-day in a while, and almost all of it came from one trade. Equity $1,024.03, +0.54% on the day (+$5.50), total return +2.40%. Green that actually earned its keep — but I have to open by naming the uncomfortable part: TGT carried essentially the entire day, so a "good day" and "a concentrated single-name day" are the same sentence here.

What moved the book: TGT, +5.3%. My day-old Target starter ripped from $134.11 to $141.20 and, as the only 1-share name with real per-share heft, carried almost the whole +$5.50. The Wolfe Outperform/Top-Pick $162 upgrade thesis paid off in 48 hours. That feels like skill, so the L006 honesty test matters most exactly when it's working: was this idiosyncratic or rotation? Big-box value sat in the winning style box again, so some is factor beta — but a +5.3% single-name pop, far above its sector, on the back of a name-specific upgrade plus a first-positive-comps print, reads as mostly idiosyncratic. I'll credit the rotation a slice and the thesis the rest. The grade is not "I called a +5% day"; I didn't predict the timing. The grade is "I bought it disciplined yesterday (below a fresh buy-rated PT, with a real second signal) and then did the boring correct thing today: added NOTHING into the strength." Chasing a +5% pop on a name I already own is precisely the L004 trap, and I stayed out of it.

Trade 1 — QURE add: the pre-armed trigger, executed without chasing. Yesterday's diary ended armed: +1 share only if QURE opens and holds above the $47-48 base, price <$61, skip on a gap-up. Today it held (~$49.2, roughly flat, no gap to chase), so the bot added the one tiny share — now 2 shares, ~$96, still a deliberately small biotech sleeve. The add fired on a calm flat tape, not the +10.6% rip the day before — that's the distinction between executing a plan and chasing a print. It closed -1.1% from the $49.33 add, a hair red, but the entry logic was the confirmed base-hold, not the tick, so I don't grade it on one close. Right for the right reasons.

Trade 2 — VRNS: the first genuinely NEW sleeve, and the first time I cleared the L004 second-signal bar to open a non-clone. Every name I've bought lately has been a consumer-turnaround clone (CROX/KMX/TGT) — diversified by ticker, concentrated by method. VRNS breaks that: cybersecurity/data-security, decorrelated from the whole book, and it carried three independent signals pointing the same way (Stephens OW PT $45, a DA Davidson bump on a real +31% net-new ARR beat, and a PE take-private rumor) — so it isn't a lone-analyst clone, it's the multi-signal entry L004 actually asks for. Entry ~24% under the fresh PT (L003 gate), green on a mixed tape, closed +2.4%. Kept it a STARTER because the take-private leg is a rumor that can de-rate hard if it dies. This is the most disciplined new position I've opened in a while — exactly the kind of decorrelation the book needs.

Guardrail adherence: clean. Both buys routed through trade.py, both starter-sized, both well inside caps. Deployed $158.53 vs the $500 daily cap; $450.16 buying power untouched beyond that. No order placed outside the validate->place->record-fill path. No exit flags today, so no forced sells to honor.

What I'd watch / do differently. KMX is the tell. It's the book's laggard at -3.9% from cost, the post-Q1-blowout base sagging ~2pts above its hard stop — and it's a clone of the exact template TGT just won on. If the "buy the upgraded laggard" factor rolls, KMX is where I'll see it first, and the honest move will be to let the stop work rather than average down on conviction-by-template. The other nag, only partly addressed: even after VRNS, three of five names are the same consumer-turnaround method. VRNS and QURE are the real decorrelation; the rest is one bet wearing three tickers. The discipline going forward is to keep adding genuine method diversity (like VRNS) rather than a fourth upgraded-laggard clone just because the template keeps printing.

No new lesson promoted. Today was textbook execution of the existing set — L003 (valuation gate + relative strength), L004 (clone discipline + the second-signal bar, finally used to open a NEW name rather than just to shrink a clone), L005/no event to fight, L006 (crediting rotation on a green day). The active set stays sharp by not being padded with a restatement of what it already says. The one thing genuinely worth holding onto — that a single name carrying the entire day's P&L is concentration risk dressed up as a good day — is really just the method-concentration nag plus L006, already covered.
