Rewrite the source pack so it says what to DO. The mirror and the lesson rows follow on sibling cards; this one owns the wording.

Go unit by unit. For each of the 15, decide keep (it is method — state it positively, 5-8 lines) or migrate (it is an incident — its body leaves, and a one-line prescriptive residue may stay if the method inside it is real). The four already known to be method: BOTH content axes, AC satisfiable inside the boundary, one update_plan_item per card, no shortcuts. The precondition-verification head is the fifth — name the preconditions this card leans on, verify each against shipped reality, cite where you checked — and its five limbs plus the asserted-absence limb and the context-ref gate are the migration candidates.

Write the table as you go, one row per unit: unit, keep or migrate, and for a keep the line count before and after. The table is the deliverable a reviewer actually reads — a 600-line prose diff is not auditable any other way, and the only question anyone will ask is what got dropped.

Do not delete a paragraph whose lesson row does not exist yet. The sibling card writes those; where they are not written, leave the text and mark the row pending rather than shipping a gap.

Acceptance criteria

• All 15 units appear in the table with a keep/migrate disposition; the row count is 15.
• Every kept unit is stated as an instruction — what to do, in the imperative — and carries no incident narrative, no fixture and no warrant tag.
• The precondition head survives as a rule; its limbs are marked migrate with the target sourceRef named per limb.
• phase-deepen.md's cautionary-register count is below 61 and its prescriptive count above 2, measured with the epic's script and both numbers quoted in the PR body.
• No unit is marked migrate without a named destination row or an explicit pending.
• The change lands via a branch and PR; no direct commit to main.
