v0.3.6

Fixed

• Sheet.step(boss) on a prismatic part fails loudly instead of silently
  dropping the height (#631): declaring a turned .step() at a cylinder that is
  really an external boss set orientation="z", which made render_height_ladder
  suppress the overall-height dim on the assumption the OD/step chain conveyed it —
  but on a prismatic box that chain never renders, so the height vanished and
  nothing replaced it (11 → 10 annotations). The build now detects a StepFeature
  coincident with a BossFeature (same axis, origin, diameter) — a combination
  that can never be legitimate — and raises a clear ValueError pointing to
  .boss() (which renders its own ø and height per #632). Legitimate turned shafts
  have steps but no coincident boss, so they are unaffected.
• detail_view=True no longer a silent no-op when the detail can't be placed
  (#630): a part whose lint recommends a detail view (step_dim_dropped) but whose
  crowded band is full-width (e.g. a shelled cover's stacked face levels) can't be
  enlarged legibly and still fit alongside the main views — so detail_view=True
  produced a drawing byte-identical to False, silently ignoring the opt-in. It
  now records a detail_unplaceable warning naming the reason and an actionable
  remedy (dimension manually / move onto its own sheet), so the opt-in is
  observable. Parts whose detail does fit are unchanged.
• Imperative --script round-trips the title-block fields + sheet furniture
  (#775): the imperative flavour reproduced only title/number/tolerance/drawn_by/
  scale/page, dropping the material/date/revision/company fields (#766) and
  the frame/zones/projection furniture (#767/#768/#769) — so a regenerated
  imperative script didn't match the direct CLI. They now ride the emitted script's
  cog config block and its build_drawing(...) call (the Sheet flavour already
  round-tripped them), and the CLI forwards them to generate_script.

Internal

• Fast-tier dense-sheet canary for the #733/#734 strip-pressure regression
  (#737): a synthetic contended-front-strip fixture that drops a step-height
  principal dim on the pre-#734 commit and stays clean on main — closing the
  fast-tier gap the #733 regression fell through (only the CI-only slow CTC
  fixtures exercised real strip pressure before).
• Layout-hypothesis fuzz tier is now a reproducible PR gate (#692):
  derandomize=True makes every run generate the same fixed example set (with
  print_blob for paste-able reproduction), so a failure recurs deterministically
  instead of surfacing on a seed-dependent minority of runs; exploratory fuzzing
  moves behind DRAFTWRIGHT_FUZZ_EXPLORE=1. The two test_make_drawing.py xdist
  observations (#669) were investigated and found non-reproducible — both tests are
  non-flaky by construction/measurement on current main.
