PROTO-0271H - Holographic CLI/operator witness playback

[flyingrobots]

Summary

Convert one CLI/operator product read path to holographic slice witness output while keeping global scans explicit in diagnostic, export, checkpoint, or plumber commands.

Parent Design

• PROTO-0271 - Holographic slicing and streaming checkpoint basis #626
• docs/design/0271-v18-holographic-slicing-checkpoint-basis/v18-holographic-slicing-checkpoint-basis.md

Required Proof

CLI tests must prove machine-readable output includes basis id, touched shard ids, tail witness range, completeness, obstruction when present, and no hidden product-read materialization.

Roadmap Slot

• Release lane: v18.0.0
• Feature area: materialization-query-index
• This issue is one implementation slice from PROTO-0271.

[flyingrobots]

Design doctrine update for this PROTO-0271 slice landed in PR #641, commit 8969ce73.

Relevant doc anchors:

• docs/design/0271-v18-holographic-slicing-checkpoint-basis/v18-holographic-slicing-checkpoint-basis.md now has an Echo-Derived WARP Doctrine section.
• docs/ARCHITECTURE.md now has a Graph-shaped readings section.

Implementation consequence for this issue: treat witnessed causal history as authority; graph-shaped values are observer-relative readings; Git/CAS byte hashes, retained payload hashes, commitment/proof refs, basis identity, and semantic reading identity must stay separate; missing witness/rights/budget/support evidence must surface as obstruction/residual/redaction/plurality/rehydration posture, not hidden full-materialization fallback.
