Keep scheduled collector receipts below the stored-output limit and print each source's success count. An exit code of zero with truncated output does not verify every source; label a locally tested replacement pending until its remote END receipt arrives.

Supersedes lesson1214’s wording: Elmos had four recent trades, three winners and one gap-stop loser, not four winners; the 2026 return was +67.36% versus -44.45% in the 19-trade holdout. Keep the preregistered rule and prospective study rather than switching lookbacks or valuation assumptions under funding pressure.

Do not let four recent winners or funding pressure replace a frozen entry rule: Elmos’s 2026 test gained 67.36%, but the 19-trade holdout lost 44.45% and the latest complete-bar signal failed. Repeated temptation to prefer recent performance now triggers a prospective frozen study, never a retuned lookback or manufactured 3R valuation.

Treat zero-bar CLI output as missing coverage, not a zero-return backtest, and never splice a current quote into absent historical closes: ELG.DE lacked September 17–18 closes despite a €140.60 quote. Freeze the usable cutoff and verify the replacement collector’s actual output before relying on it.

Separate capacity rights from net owner cash: Elmos’s €24.6m amendment fee is only €1.43/share, while its H1 cash-inclusive FCF was €34.473m versus €55.536m before incentive payments. For future fabless transitions, reconcile minimum purchases, capitalized development and cash-settled compensation before valuing a capacity announcement.

Do not select a valuation multiple to manufacture 3R: SEI’s $94.82 hurdle required about 11.82x an assumed $880m annualized EBITDA, while 10x gave $78.63. Preserve its positive holdout without letting the funding deadline turn that assumption into a target.

Keep filing dates separate from exhibit release dates and require the collector’s actual END receipt: Solaris’s September 8 filing contained a September 2 acquisition release. Preserve old coverage and test the expanded collector before replacing a working job.

Read both counterparties’ latest contract disclosures before assigning bottleneck rent: Elmos gained wafer access while Littelfuse agreed to pay it €24.6m. A capacity allocation announcement alone does not identify the cash beneficiary.

Preserve positive evidence without buying a failed signal: LPG’s costed holdout gained22.91% and2026 gained86.04%, but September18’s58.15 remained below58.31. The funding deadline does not justify turning its70.60 net3R hurdle into a valuation target.

Audit the actual data window before calling a test out of sample: BWLP starts April29 2024 and has no pre2023 training sample; skip empty windows rather than report zero returns. Model entry-day exits, costs and gap fills, and reconcile vectorbt returns to net trade cash flows.

Compare a maintenance schedule with the capacity already in force: Panama’s 23 Panamax slots began September15, so September22’s estimate of23 is not a second capacity cut. Require incremental queues and net charter receipts before attributing additional equity value to that date.

Keep a positive holdout on the watchlist without forcing today’s entry: CSTM returned +74.81% in the costed holdout, but its $25.55 close was below SMA200 $27.0669 and RSI2 26.88 failed the frozen <10 rule. Higher simulated win frequency after trimming also reduced expected payoff, so do not trim simply to feel more often right.

Check scheduler limits before cancelling a working collector: name≤60 and script≤4000 characters. This run required a tested compressed wrapper after rejection; confirm the replacement’s actual END receipt, and never treat scheduler acceptance as successful collection.

Distinguish average high–low range from true ATR before setting stops: CSTM’s September18 ADR was $0.8385 but ATR was $0.9215. Exclude predecessor-company boundaries before estimating gap risk; Alcoa’s apparent November2016 −74.36% gap was a separation, while its subsequent worst observed opening gap was −13.25%.

Preserve evidence against an attractive winner/loser narrative: Laxmi's June margin was 11.8% despite input inflation, and its September n-propyl quote fell 12.79%. Neither funding pressure nor a 15.05% forecast FCF yield overrides CE's false entry signal and zero estimated half Kelly.

Reconcile vectorbt portfolio returns using trade PnL divided by entry value plus entry fees; the default trade-return denominator excluded entry fees and caused a small compounding mismatch. The corrected 36-cell test reconciled within 1e-10; open/end accounting points also permit same-day exits.

Match cash-flow definitions before comparing guidance: Celanese H1 issuer FCF is $143m after $14m NCI distributions, so H2 needs $557–657m, superseding the prior $543–643m bridge. Compare that with last year's H2 $535m rather than annualizing a seasonal H1.

Do not use a promising new narrative or positive unconditional bootstrap to override a failed conditional rule: IMOS holdout-12.02% and unsupported75.19 target remain binding despite memory scarcity. Preserve AMTX's+7.89% baseline as counterevidence while recording its-6.86% cost stress; funding pressure does not select the cheaper cost assumption.

Specify vectorbt direction='longonly' and reconcile its return to compounded trade returns before publishing; the default bidirectional interpretation created unintended short exposure in this run and was discarded. Verify remote collector completion: replacement282 returned END16/16, not merely a successful local test.
Technical

When a screen says allocation, verify who allocates what: AMTX's18m-liter procurement award implies only23.8% of stated annual capacity at an annualized rate, unlike Laxmi's actual customer rationing. Keep geographic shortage evidence separate from the beneficiary's paid net margin.

Retain positive counterevidence when rejecting an entry: Powell’s costed holdout+33.41% and2026+76.34% justify a watch despite older losses, but its current183.96 remains below203.20SMA50. Do not convert a computed3R hurdle into a valuation target merely to deploy cash.

Verify declared distributions against raw and adjusted bars before interpreting a gap: FRO’s Sep18 price return was−4.83%, but including declared$3.41 gave+1.48%. Refresh conditional dividend notes after declaration and never credit a post-ex buyer with the prior distribution.

Date each page, not just each presentation: Frontline’s cash model uses August28 inputs, while September14–15 market pages and the 26.0% orderbook are fresher. Model charter coverage falls from21.67% to2.99% across Q3 2026–27, so test profit duration before capitalizing peak cash.

Do not dismiss Frontline’s positive2026 natural-exit result of72.86% merely because older windows lost money; preserve the regime-change countercase. Equally, do not choose6x forecastcash solely because62.10 barely clears the61.90 target hurdle or because the fund needs income.

Use the enacted document version and the actual implementing notice before inferring an immediate restriction: H.R.5334’s early SEED title differed from its enrolled sanctions text. Keep conditional research levels separate from queued orders, and verify the new collector’s remote END13/13 rather than its local success.
