docs(product): Phase 0 promote AR-designed walk identity

[scrimshawlife-ctrl]

Outcome

Promote the ratified near-term product identity from audio-first to AR-designed adaptive walking experience in binding and repository-context documentation, while preserving movement as gameplay authority and audio as a required supporting channel.

Dependencies

Freeze #249 merged. Redesign recovery #251 merged. Device lanes are armed with tip-bound receipts. No production or mesh dependency.

Intended paths

• docs/SOLO_MVP_SCOPE.md
• WAYKIN_SPEC.md
• README.md
• ARCHITECTURE.md
• docs/legal/TERMS.md
• skills/**/references/REPO_CONTEXT.md
• .grok/skills/**/references/REPO_CONTEXT.md
• skills/waykin-audio/SKILL.md
• .grok/skills/waykin-audio/SKILL.md
• docs/design/AR_MVP_FREEZE.md
• docs/design/CONTINUATION_PLAN.md
• product-identity metadata or comments explicitly enumerated by P0.9/P0.10

Frozen paths

• App/AR/**
• App/Resources/Companion/**
• docs/assets/companion/**
• all USDZ assets and mesh/art pipeline scripts
• gameplay, movement, Bond, persistence, and event-generation behavior

Acceptance criteria

• Binding docs define Waykin as AR-designed, not audio-first.
• AR is the primary designed session surface when capability allows.
• Movement remains gameplay authority.
• Audio remains a required supporting and pocket-safe accessibility/presence channel.
• No Swift behavior or asset changes.
• Historical uses of audio-first remain clearly labeled historical where retained.
• Repository context and agent/audio skills use the promoted identity consistently.

Required validation

• rg -n -i 'audio-first|audio first' --glob '!**/receipts/**'
• make check-core-isolation
• make check-lira-usdz
• python3 scripts/validate_collaboration_coordination.py
• git diff --check
• CI canonical validation

Non-goals

• AR-default UX implementation
• AR renderer, placement, loader, mesh, animation, or asset changes
• New gameplay mechanics or presentation command cases
• Outdoor/device quality claims
• Multi-activity or multi-companion scope

Evidence boundary

OBSERVED documentation and static-validation results only. Physical-device behavior remains NOT_COMPUTABLE.

Handoff state

NONE

Implementation is ready in PR #253 at 6660ca4. All macOS canonical, Swift package, native iOS, and UI checks passed. Frozen AR/mesh paths are unchanged. Awaiting formal approval and merge.
