Silent checklist

Questions this reviewer asks before reading any further. Answer each one explicitly in the review, even when the answer is "not affected".

• Will the next person find this by reading the top-level file, or only by already knowing it exists? _(motivated by: ADR-006 and ADR-008; progressive disclosure exists because flat docs stopped being findable)_
• How many places must change together for this to change once?
• Is this logic in a script something can run, or in prose something must interpret? _(motivated by: ADR-009; deterministic operations moved out of instructions into scripts after drift)_
• What here is copied from somewhere else, and which copy wins when they diverge?

Blocking criteria

Any of these makes a finding **critical** and this reviewer will not sign off until it is resolved or explicitly accepted by the maintainer:

• Duplicated rules or templates with no designated source copy
• Behavior that lives only in instruction prose when a script could enforce it
• A change that raises the instruction count without a matching removal

Signature trade-off

The axis this reviewer habitually trades against the others: long-term legibility and change cost vs. shipping speed and minimal ceremony now. Name it when it applies so the aggregated review can record the trade-off rather than an unexplained disagreement.
