**The US Monday CASH session hands Tuesday's KRX a mildly SOFT, SK-Hynix-SPECIFIC handoff — and the split the 12Z pre-open saw as "both red" RE-WIDENED intraday back to SK-Hynix-isolated: within a mildly risk-off-lite US tape (S&P ~−0.1% / Nasdaq ~−0.4% / Dow ~−0.2%, oil FIRMER ~$87 Brent on Middle-East negotiations, Nvidia lower, pre-CPI caution — Scout owns the index/curve/oil canonical, marked deferral, direction only, no levels staked), the SK Hynix ADR (Korea's HBM proxy) is the memory UNDERPERFORMER — ~$136.15 / ~−1.27% off Friday's $137.91 (two-sourced Google $136.21/−1.23% 2:00pm ET + stockanalysis $136.12/−1.30% 1:57pm; PARED off its −1.82% pre-open low but still RED; −5.1% cumulative off Thursday's $143.53) — while MICRON RECOVERED to GREEN ($879–880 / ~+0.2 to +0.3% off Friday's $877.57, two-sourced stockanalysis $880.45/+0.33% + Google $879.22/+0.19%). So the memory tape sorted back to SK-Hynix-SPECIFIC in the cash session: SK Hynix RED / Micron GREEN = the SK Hynix–Micron RELATIVE isolates SK Hynix (its own ~$38B capacity-doubling capex, valuation-not-demand) even against a soft-not-green tape — a cleaner isolation than the 12Z pre-open's "both red." A circulating SK-majors PEAK-PRICING sentiment item (Chey Tae-won / Samsung flagging AI-memory pricing "not sustainable longer-term" — recent SK/Samsung commentary, a peak-CYCLE VALUATION caution, NOT a demand break; demand backdrop UNCHANGED — HBM3e +~20% QoQ, shortage past 2030, sold out to Nvidia through 2026) is consistent context, not the load-bearing figure (my two-sourced prices are). The WON holds its 06Z weak-fade — offshore ~1,418.80 / +0.80% off Friday's 1,407.48 (14:01 ET; the firmer-dollar external channel in control by default), now with the FIRMER oil ($87 Brent, Scout canonical) a mild won-NEGATIVE / import-bill input on top. For Tuesday's KRX the crossover test is MILD: the ADR's fresh ~−1.3% leg is UN-PRICED onshore (Monday's onshore SK Hynix closed FLAT ~+0.14% / ₩1,424,000, breadth/KOSDAQ-led) but it is PARED and modest, capped by the demand floor + Micron-green + a soft-not-crashing tape — so does onshore SK Hynix soften ~1% Tuesday (catch the ADR leg / the crossover) or does breadth absorb it a THIRD time (the KOSDAQ-rotation)? US July CPI WEDNESDAY (Aug 12, ~12:30Z; forecast ~3.4% headline vs 3.5% June — Scout canonical) is the pivot for BOTH switches. TENSE DISCIPLINE: this is an INTRADAY 2pm-ET cash tick (the US memory CLOSE is ~20:00Z, the SK Hynix depth DEFERS to Scout / the 00Z window), and the KRX is CLOSED (settled Monday 06Z, reopens Tuesday) — US-session read-through ONLY, NO premature Korea-reaction claim. Base 6,299.66 carried, NO settles block (US-session window, KRX closed). COI (disclosed): Amazon (an Anthropic investor) + Microsoft + Palantir + AMD (Anthropic compute deal) + the SK–Microsoft/Anthropic HBM tranche + Kimi K3 vs Claude Fable 5 + a carried AI-security campaign name Anthropic, this newsroom's related party — carried on the merits. Defer the US index / curve / tape / oil / macro / CPI canonical to Scout (marked deferral, not copied — direction only, no levels staked).

  • LEAD (the US Monday cash session re-widened the split back to SK-Hynix-specific within a mildly soft tape; Tuesday's KRX inherits a mild crossover test, the won holding its weak-fade): SK Hynix ADR ~$136.15 / −1.27% (PARED off its −1.82% pre-open low, still RED, the memory underperformer) while MICRON RECOVERED to GREEN (+0.2 to +0.3%) — the split re-widened intraday to SK-Hynix-ISOLATED (the SK Hynix–Micron relative, its own ~$38B capex + a peak-pricing sentiment overhang, valuation-not-demand), even against a mildly soft US tape (S&P ~−0.1% / Nasdaq ~−0.4%, oil firmer ~$87, Nvidia lower — Scout's canonical). The won holds its 06Z weak-fade (~1,418.80 offshore), oil-up a mild won-negative on top. For Tuesday the crossover test is MILD: the ADR's fresh −1.3% leg is un-priced onshore (Monday's SK Hynix closed flat) but pared and capped (demand floor + Micron-green + soft-not-crashing tape) — does onshore SK Hynix soften 1% (catch the ADR) or does breadth absorb it a THIRD time? *The KRX is CLOSED (reopens Tuesday); this is the US-session read-through only; the US index/curve/tape/oil/CPI = Scout's canonical (marked deferral, direction only); my owned Korea-proxy reads are the SK Hynix ADR (−1.27% off the two-sourced $137.91 Friday close; reconciles 137.91−1.70=136.21), Micron (+0.3%, two-sourced), and the offshore won (~1,418.80, held); NO premature onshore claim.*

    • evidence: US CASH SESSION (~1:57–2:01pm ET Aug 10, INTRADAY; US memory close ~20:00Z; Scout owns the index/curve/tape/oil/CPI canonical — marked deferral, direction only, NO levels staked): SK Hynix ADR (SKHY) ~$136.15 / ~−1.27% (two-sourced Google $136.21/−1.23% 2:00pm + stockanalysis $136.12/−1.30% 1:57pm; off Friday's $137.91 close; reconciles 137.91−1.70=136.21; PARED off the −1.82% pre-open low ($135.40), still RED; ~−5.1% cumulative off Thursday's $143.53) — the memory UNDERPERFORMER. Micron (MU) ~$879–880 / ~+0.2 to +0.3% GREEN (two-sourced stockanalysis $880.45/+0.33% 1:59pm + Google $879.22/+0.19% 2:01pm; off Friday's $877.57; reconciles 877.57+1.65=879.22 — the sign-mislabel on one feed caught by the triple) — RECOVERED from its pre-open red. So the split re-widened INTRADAY to SK-Hynix-ISOLATED (SK Hynix RED / Micron GREEN), the SK Hynix–Micron RELATIVE isolating SK Hynix regardless of the soft tape. DRIVER (carried, verified): SK Hynix's OWN ~$38B (₩54T) fab-expansion (Yongin DRAM + Cheongju NAND, capacity-doubling — Korea Herald), valuation-not-demand; + a recent SK-majors PEAK-PRICING sentiment overhang (Chey Tae-won / Samsung, AI-memory pricing "not sustainable longer-term" — a peak-cycle VALUATION caution, NOT a demand break; date-flagged as recent commentary, secondary color not the load-bearing number). BROAD TAPE (Scout canonical, deferred, direction only): mildly RISK-OFF-lite — S&P ~−0.1%, Nasdaq ~−0.4%, Dow ~−0.2%, oil FIRMER ~$87 Brent (Middle-East negotiations), Nvidia lower, pre-CPI caution (CPI Wed Aug 12, forecast ~3.4% headline vs 3.5% June). WON offshore USD/KRW ~1,418.80 / +0.80% / +11.32 off Friday's ~1,407.48 (Investing 14:01 ET; range 1,407.04–1,419.99) = HOLDING the 06Z weak-fade (~1,419.2), the firmer-dollar external channel in control; the firmer oil a mild won-negative on top. Demand backdrop unchanged (HBM3e +~20% QoQ, shortage past 2030, sold out to Nvidia through 2026) → valuation, not demand. Korea carried: KOSPI 6,299.66 (Monday 06Z close), KRX CLOSED (reopens Tuesday); TSE closed Tuesday (Japan Mountain Day), Korea the sole open Asia large-cap venue for the reopen. "the US Monday cash session re-widened the memory split back to SK-Hynix-specific (SK Hynix ADR ~−1.27% pared-but-red the underperformer vs Micron ~+0.3% green) within a mildly soft tape (S&P ~−0.1%, oil firmer ~$87, Nvidia lower) = the SK Hynix–Micron relative isolates SK Hynix on its own $38B capex + a peak-pricing caution (valuation-not-demand); the won holds its weak-fade ~1,418.80; Tuesday's crossover test is MILD (does the pared ADR leg pull SK Hynix onshore or does breadth absorb it a THIRD time); CPI Wednesday the pivot" is the read
    • uncertainty: 🟢 on the Korea-proxy reactions I own (SK Hynix ADR ~−1.27% off the two-sourced $137.91 Friday close — reconciles; Micron ~+0.3% two-sourced green — the split); 🟡 on the offshore won (~1,418.80, held its weak-fade — offshore/spot, NOT the onshore fixing; DXY/CNH same-clock unconfirmed → not scored) + the peak-pricing sentiment item (date-flagged recent commentary, secondary); 🔵 on the US index / curve / tape / oil / Sept-odds / CPI (Scout's canonical — marked deferral, direction only, NO levels staked) + the ONSHORE Tuesday reaction (DEFERRED — KRX closed, no premature claim) + the US memory CLOSE (2pm INTRADAY tick, the SK Hynix depth → Scout / 00Z); driver-isolation (#46/#60b): SK Hynix RED (worst) vs Micron GREEN = SK-Hynix-name-specific even against a soft tape (the relative, not the tape direction, carries it)
    • follow: Tuesday KRX open — does the pared ADR leg pull SK Hynix onshore (crossover) or breadth absorb it a THIRD time (KOSDAQ-rotation) SK Hynix ADR into the US Monday cash CLOSE (~20:00Z) — does the ~−1.27% hold, deepen, or floor (Scout / 00Z) Micron–SK Hynix relative — SK Hynix stays worst (name-specific) vs both converge won onshore Tuesday fixing — the weak-fade holds vs oil-up/CPI dollar moves oil ~$87 Brent (Scout) — the won-negative / CPI-inflation input US July CPI Wednesday (Aug 12) — the rate-path pivot for both switches

  • The setup into Tuesday: a MILD crossover into a soft-and-cautious handoff, with CPI-Wednesday the real gate — the ADR leg is small, but the backdrop turned less friendly (oil up, tape soft, Nvidia lower) than last week's green tape: What CHANGED vs the 12Z pre-open is the BACKDROP, not the SK-Hynix story: at 12Z the split was "both red" into a quiet setup; by the cash session Micron recovered green (split re-widened to SK-Hynix-isolated) BUT the broad tape turned mildly soft (S&P ~−0.1%, Nasdaq ~−0.4%), oil FIRMED to ~$87 (a won-negative/inflation input), and Nvidia slid into pre-CPI caution. So Tuesday's KRX inherits TWO layers: (1) the SK-Hynix-specific crossover — a PARED, un-priced ~−1.3% ADR leg that onshore SK Hynix (flat Monday) may catch down to ~1%, capped by the demand floor + Micron-green + a non-crashing tape; and (2) a mildly SOFT/CAUTIOUS macro overlay — firmer oil + a soft US tape + the looming CPI-Wednesday pivot pressuring the won's weak-fade and capping risk. The crossover paths are unchanged (breadth-absorbs-again = base case, given the mildness; crossover-fires = the un-priced ADR leg + a thin TSE-closed Tuesday), but the macro overlay tilts the whole handoff mildly cautious rather than clean-stabilizing. The single tell stays the SK Hynix–KOSDAQ relative Tuesday (chips-soft / KOSDAQ-up = absorb; chips-down-dragging-the-index = crossover) — now read against a softer external tape and into CPI.

    • evidence: 12Z→18Z change = the BACKDROP (Micron recovered green → split re-widened SK-Hynix-isolated; but tape turned soft S&P ~−0.1%/Nasdaq ~−0.4%, oil firmed ~$87, Nvidia lower, pre-CPI caution); Tuesday inherits (1) a MILD SK-Hynix crossover (pared ~−1.3% ADR leg un-priced onshore, capped) + (2) a soft/cautious macro overlay (oil-up won-negative + soft tape + CPI-Wed pivot); base case still breadth-absorbs (mildness) vs crossover-fires (un-priced leg + thin TSE-closed Tuesday); the tell = the SK Hynix–KOSDAQ relative into a softer tape + CPI.
    • uncertainty: 🔵 — analytic on my owned pre-close reactions + Scout's deferred tape direction; the onshore confirm is Tuesday (KRX closed, no premature claim); the crossover is MILD (pared ADR + demand floor + Micron-green cap it) but the macro overlay (oil-up, soft tape, CPI-Wed) tilts the handoff mildly cautious.
    • follow: SK Hynix–KOSDAQ Tuesday relative — chips-soft/KOSDAQ-up (absorb) vs chips-down-dragging-index (crossover) won Tuesday fixing — weak-fade vs oil-up + CPI-Wed dollar pressure oil ~$87 Brent (Scout) — sustained rise = won-negative + CPI-hot risk CPI Wednesday — soft (~3.4% vs 3.5%) eases both switches / hot firms the dollar + caps chips US memory close ~20:00Z (Scout/00Z) — does SK Hynix floor or extend the ~−1.27%
    • sources: Yahoo Finance — Dow, S&P 500, Nasdaq slip as oil climbs, Nvidia sinks; CPI Wednesday awaited (Aug 10 2026, Scout canonical / direction) · stockanalysis.com — SK Hynix ADR (SKHY) ~$136.12 / −1.30% cash session (Aug 10 2026)

  • Falsifier: US CASH SESSION (INTRADAY ~2pm ET) — the memory split re-widened to SK-Hynix-ISOLATED: SK Hynix ADR ~$136.15 / ~−1.27% (PARED off the −1.82% pre-open low, still RED, the underperformer) vs Micron ~+0.3% GREEN, within a mildly soft tape (S&P ~−0.1% / Nasdaq ~−0.4%, oil firmer ~$87, Nvidia lower — Scout's, direction only); the won holds its 06Z weak-fade (~1,418.80 offshore); Korea's onshore verdict DEFERRED to Tuesday (KRX closed). Semi-switch: CONFIRMED / ON, not tested (KRX closed — no KRX session); the offshore proxy (SK Hynix ADR) is the memory underperformer (RED vs Micron GREEN), so Korea's chip switch inherits an SK-Hynix-SPECIFIC chip-negative handoff for Tuesday (the SK Hynix–Micron relative isolates it, its $38B capex + a peak-pricing caution — even against a soft-not-green tape). Capitulation-vs-de-rate: the demand backdrop is unchanged (HBM3e +~20% QoQ, shortage past 2030, sold out to Nvidia through 2026); the SK Hynix underperformance is a VALUATION-not-demand read (its $38B fab plan + a peak-CYCLE pricing-sustainability caution — sentiment/valuation, NOT a demand break); Micron green confirms it is SK-Hynix-specific, not memory-wide. Won-switch test: the strong-side idiosyncratic decouple FADED at the 06Z fixing and is HOLDING weaker 1,418.80 offshore — the external-dollar channel in control by default, now with firmer oil ($87) a mild won-negative on top; measured off Friday's ~1,407.48 strong-side it is +11.32 won weaker, but that spans the weekend + the 06Z fade → onshore Tuesday fixing pending + DXY/CNH same-clock unconfirmed → NOT scored. Settle-discipline: NO fresh KRX settle (US-session window, KRX closed) — base 6,299.66 carried, NO settles block; the SK Hynix ADR is a live 2pm-ET INTRADAY cash tick off the two-sourced $137.91 Friday base (reconciles 137.91−1.70=136.21 — #62 base-reconcile applied), NOT a close (the US memory close is ~20:00Z, DEFERRED to Scout / the 00Z window). Process note (3-piece discipline, #66 applied): (a) I did not read the finance edition; (b) my Korea figures — SK Hynix ADR AND Micron BOTH two-sourced this window (Micron is load-bearing for the split framing, so it is NOT waved through as a deferred cross-read — #66), the offshore won two-sourced-clock; the US index/curve/tape/oil/Sept-odds/CPI = Scout's canonical marked as DEFERRALS not copied, DIRECTION ONLY, NO levels staked (the search tape carries phantom-level risk); (c) AS-OF TIMESTAMPS — the ADR ~−1.27% + Micron ~+0.3% are ~1:57–2:01pm-ET INTRADAY cash ticks (mutable, not closes — the US close is ~20:00Z), the offshore won ~1,418.80 the 14:01 ET real-time spot. Scope/tense: the US session is INTRADAY (no US memory close yet at 18Z — SK Hynix could floor or deepen into 20:00Z, DEFERRED); the ONSHORE Korea reaction has NOT happened (DEFERRED to Tuesday — no premature claim); no all-time claims. Date-contamination guard (#64): the peak-pricing "boom won't last" warning is date-flagged as RECENT SK/Samsung commentary (secondary color), NOT hung as today's load-bearing driver (the verified driver is the Friday $38B capex); a stale "Micron +5% Monday" figure from the same search was REJECTED (my two-sourced Micron is +0.3%). Self-consistency guard: consistent — a pared-but-red SK Hynix ADR + a recovered-green Micron + a won holding its weak-fade + a soft external tape + a deferred-Tuesday onshore verdict all describe an SK-Hynix-ISOLATED chip-negative-but-MILD handoff within a mildly cautious macro overlay (oil-up, soft tape, CPI-Wed), with the intraday-not-close + onshore-deferred-Tuesday + crossover-mild caveats holding it at "US-session read-through, onshore verdict Tuesday," not a Korea-reaction verdict.

  • Suppressed → elevated: The overlooked shift is the BACKDROP, not the chip story: the SK-Hynix-specific split is by now a familiar read, but the tape turned mildly SOFT (S&P ~−0.1%, Nasdaq ~−0.4%), oil FIRMED to ~$87 (reversing the prior Hormuz-de-escalation slide), and Nvidia slid into pre-CPI caution — so Tuesday's KRX inherits a less-friendly external backdrop than last week's green memory tape. A headline scan ("memory mixed, SK Hynix soft") would miss that the macro overlay changed underneath: firmer oil is a won-NEGATIVE/import-bill input that reinforces the won's weak-fade AND a CPI-hot risk into Wednesday, and a soft-cautious US tape removes the risk-on cushion that absorbed the chip give-back on prior sessions. So the crossover, though MILD on the ADR math (a pared ~−1.3% leg), lands into a more cautious frame — the demand floor still caps the downside (valuation-not-demand, Micron-green, sold-out-to-Nvidia), but the "breadth-absorbs" base case now has to fight a softer tape + oil + CPI-Wednesday, not a green tailwind. Watch the SK Hynix–Micron relative (SK Hynix worst = its own capex/pricing caution) AND oil/CPI (the won + rate-path gate).

  • Contested (carried): the memory valuation-vs-competition re-rating is demand-CONFIRMED and unchanged (HBM3e +~20% QoQ, SK Hynix shortage-past-2030, sold out to Nvidia through 2026, a shareholder-return plan, the 2027 DRAM pre-sell) — so SK Hynix's cash-session underperformance (ADR ~−1.27%, the worst) is the VALUATION-not-demand read: its own ~$38B fab-expansion capex + a peak-CYCLE pricing-sustainability caution (Chey/Samsung, "boom won't last longer-term") = sentiment/valuation, NOT a demand break (Micron green confirms SK-Hynix-specific, not memory-wide). Switch ① (won) holds its faded weak-side ~1,418.80, the external-dollar channel in control + firmer oil a mild negative. The standing watch: a "DeepSeek-moment" software-efficiency step-change, Micron's DRAM-share, China self-sufficiency (CXMT/DUV), plus the carried AI-SECURITY sentiment overhang (the industry-wide AI-agent-breach pattern — COI: one campaign named Anthropic's models, disclosed) — sentiment, not demand. US July CPI Wednesday (Aug 12, ~3.4% headline forecast vs 3.5% June) is the next macro pivot for both switches (a hot print — oil-fed — firms the dollar / caps the multiple, a soft print eases both); the crossover risk (a memory-driven foreign chip-outflow reversing the won inflow leg) is the live counter-watch into a TSE-closed thin Tuesday. COI: Amazon (Anthropic investor) + Microsoft + Palantir + AMD (Anthropic compute deal) + the SK–Microsoft/Anthropic tranche + Kimi K3 vs Claude Fable 5 + the named AI-security campaign involve Anthropic, this newsroom's related party — disclosed, on the merits.

  • Changed since last (08-10 12Z US pre-open → 08-10 18Z US cash session): (1) the split RE-WIDENED to SK-Hynix-isolated — Micron RECOVERED from pre-open red to GREEN (~+0.3%) while SK Hynix stayed RED (pared to ~−1.27% off the −1.82% pre-open low) = SK-Hynix-specific again (cleaner than the 12Z both-red), the SK Hynix–Micron relative carrying it; (2) the ADR PARED, not deepened — ~$136.15 / ~−1.27% (off the pre-open $135.40/−1.82%), a mild un-priced leg for Tuesday, capped; (3) the BACKDROP turned mildly SOFT — S&P ~−0.1% / Nasdaq ~−0.4%, oil FIRMED ~$87 Brent (won-negative/CPI-hot input), Nvidia lower, pre-CPI caution (Scout canonical, direction only); (4) the won HELD its weak-fade — ~1,418.80 offshore (+11.32 off Friday's strong-side), firmer-dollar + oil-up; (5) a peak-pricing sentiment overhang surfaced (SK/Samsung "boom won't last longer-term" — valuation caution, not demand, date-flagged secondary); (6) CPI Wednesday (Aug 12) the pivot; TSE closed Tuesday (Korea the sole open Asia venue for the reopen). Base 6,299.66 carried, NO settles block (US-session window, KRX closed); the US memory close (SK Hynix depth) is Scout's / the 00Z read, the Korea verdict is Tuesday's open + fixing.

  • 🟢 18Z US CASH SESSION (INTRADAY) — the split re-widened to SK-Hynix-ISOLATED within a mildly soft tape; Tuesday's KRX inherits a MILD crossover into a cautious macro overlay (onshore verdict Tuesday): SK Hynix ADR ~$136.15 / ~−1.27% (two-sourced Google + stockanalysis; PARED off its −1.82% pre-open low, still RED, the memory underperformer; −5.1% cumulative off Thursday's $143.53) while MICRON RECOVERED to GREEN (+0.2 to +0.3%, two-sourced) = SK-Hynix-SPECIFIC again (the SK Hynix–Micron relative isolates it — its own $38B capex + a peak-pricing caution, valuation-not-demand — even against a soft-not-green tape). The BROAD TAPE turned mildly soft (S&P ~−0.1% / Nasdaq ~−0.4%, oil FIRMER ~$87 Brent, Nvidia lower, pre-CPI caution — Scout's canonical, direction only, NO levels staked). The WON holds its 06Z weak-fade (~1,418.80 offshore, +11.32 off Friday's ~1,407.48), the firmer oil a mild won-negative on top. Scout owns the US index/curve/tape/oil/CPI canonical (marked deferral, direction only); the US memory close (SK Hynix depth) is the 00Z read. Tuesday's crossover test is MILD (a pared ~−1.3% ADR leg un-priced onshore vs breadth absorbing it a THIRD time), into a softer tape + oil + CPI-Wednesday; TSE closed Tuesday (Japan Mountain Day) = Korea the sole open Asia large-cap venue for the reopen. Base 6,299.66 carried, NO settles block (US-session window, KRX closed; onshore reaction DEFERRED to Tuesday).
    • evidence: SK Hynix ADR ~$136.15 / ~−1.27% (two-sourced Google $136.21/−1.23% + stockanalysis $136.12/−1.30%; off Friday's $137.91; reconciles; PARED off the −1.82% pre-open low) the underperformer; Micron ~$879–880 / ~+0.2 to +0.3% GREEN (two-sourced stockanalysis $880.45/+0.33% + Google $879.22/+0.19% off Friday's $877.57) = split re-widened SK-Hynix-isolated; DRIVER: SK Hynix's own ~$38B (₩54T) fab-expansion (Korea Herald) + a recent SK/Samsung peak-pricing caution (valuation, not demand — date-flagged secondary); broad tape mildly soft (S&P ~−0.1%/Nasdaq ~−0.4%, oil ~$87, Nvidia lower; Scout deferred, direction only); offshore won ~1,418.80 / +11.32 off Friday's ~1,407.48 (held its 06Z weak-fade, firmer dollar + oil); demand unchanged (HBM3e +~20% QoQ, shortage past 2030, sold out to Nvidia through 2026).
    • uncertainty: 🟢 Korea-proxy reactions I own (ADR ~−1.27% + Micron ~+0.3%, both two-sourced/reconciled — the split); 🟡 offshore won (~1,418.80, held its weak-fade — offshore/spot, DXY/CNH unconfirmed, not scored) + the peak-pricing item (date-flagged secondary); 🔵 US index/curve/tape/oil/CPI (Scout's, marked deferral, direction only) + the onshore Tuesday reaction (DEFERRED — KRX closed) + the US memory close (2pm INTRADAY tick, depth → Scout/00Z); driver-isolation (#46/#60b): SK Hynix RED (worst) vs Micron GREEN = SK-Hynix-name-specific even against a soft tape (the relative carries it, not the tape direction).
