PropertyAudit gained three required cylinder fields; the pre-existing
divergence/goal-shortfall tests construct it via _make_audit, which
wasn't updated.

A focused sibling to audit-ara-portfolio: that skill audits baselines/plans/SAP;
this one audits the *recommendations themselves* — why a measure was or wasn't
offered. Motivated by the portfolio-814 review (Khalim's HHRSH-on-community-
heating, missing-HHRSH, missing-secondary-heating-removal, and a neighbour split).
Adds:
- .claude/skills/find-weird-recommendations/SKILL.md — scan -> neighbour scan ->
live re-model deep-dive -> root-cause -> codify, with a seeded known-bug
catalogue and the query-safety rules inherited from audit-ara-portfolio.
- scripts/audit/anomalies.py: new `plan-stops-short-of-goal` HIGH check — the
default plan ends below the goal band on an unlimited-budget scenario (the
deterministic worklist for "why didn't this get recommended X"). Adds
scenario_budget to the bundle/query so budget-capped scenarios are excluded.
- scripts/audit/neighbour_divergence.py: groups a portfolio by (postcode,
property_type, built_form) and flags effective-SAP outliers vs the cohort
median. Never touches the 26m-row recommendation table, so it is safe
portfolio-wide.
- Tests for both (12 passing).
