/**
 * Plan reality rows (multi-agent wave D1, release promise P5).
 *
 * {{PLAN_REALITY_ROWS}} and its variants render lib/plan-reality.ts's one row
 * table into the plan-review skills and the autoplan phase files, so the rows a
 * review must carry, the `REALITY:` line a reviewer emits and the check a
 * parent runs never drift apart:
 *
 *   {{PLAN_REALITY_ROWS:eng}} / {{PLAN_REALITY_ROWS:ceo}}
 *       the operative block for an interactive plan review (tier 1 row ids, the
 *       bin that prints every applicable row, the line grammar, the miss rule)
 *   {{PLAN_REALITY_ROWS:deep}}
 *       the full table with each row's incident note, for the deep section
 *   {{PLAN_REALITY_ROWS:autoplan:<phase>}}
 *       one checklist item for an autoplan phase file
 *   {{PLAN_REALITY_ROWS:pregate}}
 *       the Pre-Gate rule: unattended a miss is `incomplete`, never a warning
 *   {{PLAN_REALITY_ROWS:summary}}
 *       the Completion Summary line
 *
 * The rows themselves are printed by `gstack-plan-reality rows` at run time so
 * the zero-headroom skills carry the contract, not eighteen rows of prose.
