The HTML and PDF present the same assessment revision. The HTML provides interactive figures and navigation; the PDF provides a paginated copy for reading and printing. This review draft presents Model 26.0 as the working assessment; final scientific adoption and harvest advice follow the assessment review process.

The report includes the updated 1991–2026 prohibited-species, groundfish, and nontarget bycatch tables, the current Appendix H introduction, and portrait layouts for narrower PDF tables. Supporting references available only in the authors’ local working files appear as text rather than download links. Manual accessibility review remains pending.

Weight-at-age development comparisons

Doubling 2025–2026 BTS observation CVs shows the remade heatmap, age-3 comparison, and numerical checks for a separate WtAgeRE sensitivity. These comparisons retain their original inputs and projection baselines.

Model 26.0 projection comparison: 2020–2024 empirical fishery weights uses the same five-year mean for catch and SSB weights, with the original assessment and projection results retained for comparison.

Extended projection comparison with original and doubled-BTS-CV WtAgeRE weights compares both forecasts with the published baseline and empirical means, including a matched control for the effect of doubling the BTS CVs.
