Phase 1 first. check_stocks_stops fired no mechanical exits — all nine positions sit above their stops (ABBV +1.6%, ANET +7.7% [breakeven-armed], JNJ -1.2%, NVDA +2.7%, REGN -2.0%, TSLA +2.0% [breakeven-armed], TSM +4.4%, V -4.0%, XOM -1.4%). Discretionary pass: every holding's research signal is still constructive — ABBV/ANET/JNJ/NVDA/TSLA/TSM are bullish buy; V is hold only because price ($365.7) sits below its fast MA, but its named bullish crossover is intact (20d 371.34 > 50d 367.96, +0.9%) and has NOT flipped, so my no-churn lesson keeps me in it; XOM's crossover is still bullish (+1.9%) and REGN's still bullish (+3.2%). No broken thesis, no earnings miss — no exits or trims.

New buys, worked through the two-axis gate (crossover clear of the ~1% noise band AND positive 50d-vs-stop geometry) across the WHOLE board, then my dynamic-diversification lesson. My book is Tech (ANET/NVDA/TSM), Healthcare (ABBV/JNJ/REGN), and singletons in Consumer (TSLA), Energy (XOM), Financials (V) — the most under-weight sectors are Industrial, Materials, Media, Utilities, Broad ETF (weight zero) and the three singletons.

Only two names clear BOTH axes decisively: AAPL (crossover +2.3%, geometry +4.1%) and MRK (crossover +5.3%, geometry +2.8%). But AAPL deepens my 3-name Tech cluster and MRK deepens my 3-name Healthcare cluster — neither diversifies. Every under-weight-sector candidate fails the gate: SYM (Industrial, crossover +0.7% — inside the noise band), SPY (Broad ETF, +0.5% — noise), WBD (Media, geometry -2.2% — a routine pullback runs through the stop); CVX (Energy) is hold, not a fresh entry (price below its fast MA). MSFT clears crossover (+5.1%) but its geometry is +0.3% — the 50d sits right on the stop, and it too is Tech. ISRG's crossover (+1.3%) is barely out of noise and it's Healthcare.

The 09-23 lesson warns me not to read the gate as an inaction bias — buy decisively when ONE name clears both axes AND diversifies. That condition is simply not met today: the names that clear don't diversify, and the names that would diversify don't clear. The 09-24 refinement says once a sector becomes a cluster I rotate to the most under-weight gate-clearer, not re-add to the cluster — and no under-weight name clears. On top of that, the macro cut against the one clean Tech clearer: the 10Y is 5.11% (up from the 4.96% of my last two runs), so adding rate-sensitive AAPL to an already-heavy Tech book is the worst-fit deployment of cash, not the best. Defensive MRK is a better macro fit but re-deepens Healthcare against the explicit 09-24 rule. Prefer nothing over a cluster-deepening trade — cash ($53,734.44) is ample and under no pressure to deploy.

No exits, no trims — held all nine positions; no broken thesis, no mechanical stop, and V's bullish crossover has not flipped. No new buys (0 of 3 used). The only decisive two-axis clearers — AAPL (+2.3%/+4.1%, Tech) and MRK (+5.3%/+2.8%, Healthcare) — both deepen clusters I already run three-deep, and every under-weight-sector candidate (SYM, SPY, WBD, CVX) fails the gate on crossover-noise, geometry, or being a hold. With the 10Y at 5.11% arguing specifically against adding rate-sensitive Tech, the disciplined call is to hold cash: this is the gate working as a filter (diversifiers don't clear, clearers don't diversify), not an inaction bias.

On 09-23 and 09-24 exactly one board name (REGN, then XOM) cleared BOTH axes AND diversified my book, so each was a decisive buy. Today, for the first time in that sequence, those two sets were DISJOINT: the only decisive two-axis clearers were AAPL (+2.3% crossover / +4.1% geometry) and MRK (+5.3% / +2.8%) — but both deepen clusters I already run three-deep (Tech ANET/NVDA/TSM, Healthcare ABBV/JNJ/REGN) — while every under-weight-sector candidate FAILED the gate (SYM +0.7% crossover and SPY +0.5% inside the noise band, WBD -2.2% geometry, CVX a hold with price below its fast MA). So I held cash. Generalized principle: the "clears both axes" test and the "diversifies my book" test are INDEPENDENT conditions, and a buy needs their INTERSECTION, not either alone. When the gate-clearers all deepen existing clusters and the would-be diversifiers all fail the gate, that empty intersection is a correct, non-marginal HOLD-CASH — the filter working, not an inaction bias (09-23) — never resolve it by either forcing an under-weight name that fails the gate OR re-adding to a cluster (09-24). Macro corollary that broke the near-tie: the 10Y rose to 5.11% (from 4.96% on my last two runs), which argues specifically against deploying into the one clean Tech clearer (rate-sensitive AAPL) on top of an already Tech-heavy book — so when only cluster-deepeners clear, let a rising 10Y tie-break AWAY from the rate-sensitive one, reinforcing the hold. Falsifiable: track whether a name that clears BOTH axes AND rotates to an under-weight sector (Financials/Consumer/Energy singletons, or a zero-weight Industrial/Media/Utility) appears in coming runs — if one does and I take it and it holds its crossover, the disjoint-sets hold was right and simply awaited alignment; if AAPL/MRK run hard from here while my book stalls, I over-weighted the diversification test against two decisive clearers and should let crossover+geometry THICKNESS outrank sector-rotation when no diversifier clears.
