Docs: truth pass over CLAUDE.md, DRs and the MOCs (audit M13/M14/M15/M16/M19/L11/L12)

CLAUDE.md — it is loaded every session, so its errors cost the most:
- M13: it still said "No world code until the world-model spike passes
  its design review" while DR-049 has been `accepted` since 07-13 and the
  roadmap says PASSED. A hard contradiction between the two authority
  docs, with CLAUDE.md winning by being always-loaded — plausibly part of
  why Phase 2 never started. Now points at the build spec, warns it needs
  re-anchoring, and links the parked engine fork.
- Records the H2 hazard as a rule: a socket whose SparkId is missing from
  the baked AbilityDatabase silently reads Damage/Range/Cooldown 0.
- L12: the asmdef table was stale on all four rows; also notes the fifth
  compilation unit (Scripts/Editor has no asmdef) and that tests now
  reference Authoring.
- M19: per-machine setup — the machine-loss recovery checklist — was
  missing Blender + blendermcp (which the committed /art-dev skill
  hard-requires) and ctx7, and claimed a ${CLAUDE_PROJECT_DIR} in
  .mcp.json that isn't there.
- Structures / harvest / persistence / BefourStudios bullets rewritten:
  they described deleted subsystems.
- Net-zero rule honoured: the additions pushed it to 41,057 (over the
  40,960 hard limit), so two long art-pipeline bullets moved verbatim to
  the gotchas archive under a dated heading. 39,661 now — inside the
  file's own 39,936 soft ceiling.

- M14: DR-053 files the Bevy fork as PARKED. The guide was reachable from
  NOTHING — one file, zero inbound links, and its gating instruction
  lived only in machine-local memory, which CLAUDE.md explicitly forbids
  as a sole home. It now has a committed home and inbound links.
- DR-054 records this purge, including the three files that were in the
  delete set until their consumers were checked and turned out to be
  load-bearing.
- M15: 13 superseded DRs re-statused with `superseded_by`. Only DR-002
  carried the field before, though the project's own template prescribes
  it.
- M19: Home.md stated three wrong facts (latest DR, latest session, date)
  — refreshed. Pillars.md and Systems_Index.md now carry warning banners:
  both assert things the purges falsified, and Systems_Index still claims
  to be "the accurate map of what exists in code today".
- L11: the 4 genuinely-broken wikilinks fixed (typo'd DR filenames). Zero
  broken vault-internal links now.
- Session log written — the last three commits before today had none,
  breaking the protocol's own bookend rule.

Hand-written Rukhanka deformation shader: `UNITY_DOTS_INSTANCING_START` block with `_DeformedMeshIndex` must precede the `ComputeDeformedVertex.hlsl` include (macro expands at include time; else "undeclared identifier `_DeformedMeshIndex_DOTSInstancingOverrideMode`" in the DOTS_INSTANCING_ON variant = magenta), and `_DeformedMeshIndex` must also exist in the Properties block (SkinnedMeshBaker validates `material.HasProperty`).

+Moved out of CLAUDE.md verbatim to buy budget for the 2026-08-06 audit corrections (world-gate, asmdef table,
