OPS-02: Update CLAUDE.md (last reviewed 2026-04-28, pre-v0.2.0) to reflect post-release state

[DrunkOnJava]

Problem

Parent-directory CLAUDE.md (in rvt-recon-2026-04-19/) was
last reviewed 2026-04-28, the day before v0.2.0 shipped
(2026-04-29). It still says "narrow Revit 2023 ArcWall proof"
and "validated only on 2024-2026 corpus paths" as the wall
ceiling. Post-v0.2.0 reality:

• 7 IFC element classes from real RVT bytes
• 295/360 walls (82%) on 2024_Core_Interior.rvt
• 800/953 total elements (84%) across 7 classes
• Symmetric-tuple-marks-resource pattern is the load-bearing
  discovery, not yet captured in CLAUDE.md
• Walker 5b language is stale — RE-14 pipeline subsumes it

Scope

• Update "Current state — rvt-rs — what ACTUALLY works now"
  section against CHANGELOG.md [0.2.0].
• Update "What is NOT done (the blind-side gap)" to reflect
  the new gap: real geometry (placeholders today), real names
  (placeholders today), additional classes (window/roof/stair/
  MEP).
• Update "Known failure modes I've exhibited before" if any
  new patterns surfaced post-v0.2.0.
• Re-date the file (Last reviewed: 2026-MM-DD).
• The file is at parent path, NOT in the repo — but it
  influences every session, so worth fixing.

Acceptance criteria

• CLAUDE.md fact-checks against CHANGELOG [0.2.0].
• No contradictions with ROADMAP.md current snapshot.
• Last-reviewed date updated.

• Companion to M1-01 (M1-01: Reconcile README, ROADMAP, compatibility matrix, and docs #14 closed) which reconciled README/
  ROADMAP/docs but not the parent-dir CLAUDE.md.
