v0.2.12 — 2026-07-09

Sheet scripts now round-trip authored layout intent. This patch finishes the next
slice of the layout-authority work: below/right ladders, pinned edits, height ladders,
detected envelopes, and AP242 authored dimensions now survive the declarative Sheet path
without being invalidated by post-hoc placement or raw imported metadata.

Added

• Pinned edit intents route through the corridor solve. locate(..., pin=True) and
  pinned dimensions now become priority-ranked candidates in the shared corridor instead
  of fixed post-hoc edits, so user intent participates in the same ordering/spacing model
  as automatic dimensions. (#511)
• AP242 dimensional PMI lowers to authored drafting dimensions. Imported AP242
  size/location dimensions now become AuthoredDimension IR and generated Sheet scripts
  emit sheet.dimension(...); unsupported PMI records remain explicit raw fallbacks.
  (#503, #422, #62)

Changed

• place_dim is deprecated. Manual dimensions should use pinned candidate/dimension
  intent instead of the old incremental edit path.
• Prismatic height ladders and detected envelopes round-trip through Sheet scripts.
  Generated scripts now preserve StepLevelFeature and detected EnvelopeFeature
  fallbacks, preventing CTC01-style ladder swaps and raw STEP-envelope remeasurement
  drift.

Fixed

• Below/right corridors now share one solve. Side-hole locations, height ladders,
  PMI/GD&T, envelope dims, and related below/right strip occupants negotiate in the shared
  corridor rather than competing through separate late passes. (#477)
• Sheet script parity is tighter. Generated scripts preserve member positions, step
  levels, AP242 authored dimensions, raw PMI fallbacks, and detected envelopes so
  direct-vs-script CTC01 output has matching annotation names.
