[1.59.8] — 2026-05-21

fix(ux+api): v1.59.8 — UX-A5-r3 + NEW-F1-sub (HIGH + LOW bundled per FIX-PROMPT-FINAL-CONSOLIDATED). Doctrine-exception release: the 2026-05-20 FINAL REGRESSION-v1.59.7 report explicitly recommended bundling these two. UX-A5-r3 (HIGH) — after 4 ship attempts with IntersectionObserver all failed live verification, public/js/views/help.js replaces the IO entirely with a plain scroll listener. Root cause: with rootMargin -20%/-55% the trigger band ended at 45% of viewport, but scrollIntoView({block:'center'}) lands the target at 50% — JUST below the band end. The new scroll listener probes absolute heading positions every rAF, computes the heading whose top is at-or-above 30% of viewport, applies .toc-current — no band, no race, no mount-order gotcha. NEW-F1-sub (LOW) — server/index.mjs adds a late middleware that inspects req.originalUrl (not normalised req.url) and bounces any /api-prefixed request whose raw URL contains .. as 404 JSON {error: 'invalid path'}. New UX-A5-r3 lock-test + NEW-F1-sub static + behavioural guards in tests/. 971 → 973 unit. (UX-A5-r3 · NEW-F1-sub)
