workflow-fix: verify_task_body total-prose budget ignores folded follow-up rounds

Overview / Motivation

Auto-filed by the workflow-fix-on-bug protocol from a reconciler prose follow-up on task #763 (9a-bis reconcile v12, 2026-07-03).

Goal

Make scripts/verify_task_body.py check_v4_word_caps count FOLDED same-issue follow-up rounds in live_followup_rounds, so the total-prose budget scales 800 + 250 × rounds as the spec intends.

Workflow gap

• Bug observed: on #763's body carrying TWO folded follow-up rounds (deception-rubric-reanchor, neutral-contrast-and-cofit — both named in the **Context:** footer and the Methodology Rounds note), the verifier reported "total content prose is 2262 words (budget 800: 800 + 0 x 250 per extra round; Methodology excluded)" — live_followup_rounds = 0.
• Why it is a workflow gap: the WARN threshold is then far too strict for exactly the multi-round consolidated bodies the budget clause was scaled for; a Codex clean-result critic elevated the mis-scaled WARN into a lens FAIL that a reconciler round had to overrule (one avoidable reconcile invocation).
• Confidence (emitter): low-medium (reconciler: "appears not to count folded rounds; did not affect this verdict") — filed per the standing directive; the spawned session's planner verifies the detection logic with the file open.

Proposed change (candidate diff sketch — refine in planning)

scripts/verify_task_body.py (check_v4_word_caps):
- live_followup_rounds = <current detection — likely counts open children / a
-   frontmatter field that folded same-issue rounds never touch>
+ count follow-up rounds from durable signals a folded round always leaves:
+   the task's epm:same-issue-followup-run markers (via task_workflow.list_events
+   when --issue is given), OR the footer's `same-issue follow-up round` clauses /
+   the Methodology **Rounds:** note as the body-only fallback.
+ budget = 800 + 250 * live_followup_rounds
(add a test row: a body with 2 folded rounds gets budget 1300)

Scope / surfaces

• Primary target: scripts/verify_task_body.py
• Grep: grep -n "live_followup_rounds\|250" scripts/verify_task_body.py; sync SPEC.md § Conciseness caps wording if it names the detection; extend tests/test_verify_task_body.py.

Constraints / invariants

• Workflow-surface only; the verifier stays runnable body-file-only (the events-based count must degrade gracefully when only a file path is given); existing tests green + a new pinning row.
