feat(module): convert Healthy Hierarchy & Actualization Gradient to journey template (Batch D)

[paruff]

AI-Assisted Review Block

Scope: Convert final flat-heading module to the journey-template skeleton (Task #10, Batch D of 4 — final batch).

Files changed:

• docs/modules/healthy-hierarchy-actualization-gradient.mdx
• docs/.content-graph.json, docs/.content-graph-stats.json (regenerated)

What changed:

• This module already had Orient, Encounter, Integrate, Stabilize, Facilitator Note, Embody, Reflect, Assess, and Retrieval Schedule headings in place — only Learn, Frameworks, Gifts, Limitations, and Evidence were missing.
• Added a ## 🧠 Learn wrapper with a short intro, and renamed the existing "Wilber's Core Distinction" heading to ## Framework Lens: Wilber's Dominator vs. Actualization Hierarchy (content unchanged) to satisfy both the Learn and Frameworks checks.
• Added ## The Gifts of Hierarchical Discernment — four items synthesized from claims already established elsewhere in the module (the "Consequential Error" admonition's list of what the distinction makes possible).
• Added ## The Developmental Limitations and Shadows of Hierarchical Discernment — a short section naming hierarchy rationalization as the module's characteristic shadow, pointing to the full Pre/Trans Checkpoint diagnostic already present in the existing Stabilize section rather than duplicating it.
• Added the missing ## 📚 Evidence and Citations heading directly above the pre-existing citations table, which previously had no heading at all.

Not changed:

• Orient, Encounter, Integrate, Stabilize, Facilitator Note, Embody, Reflect, Assess, Retrieval Schedule sections — all untouched.
• Safety Note (Tier 1) — untouched.
• No frameworks, citations, or empirical claims were added or altered; Gifts/Limitations content is synthesized from claims already present in the module.

Validation run:

• node scripts/validate-frontmatter.js — file now passes with zero warnings (✅), down from "Missing gold-standard sections: Learn, Evidence, Frameworks, Gifts, Limitations".
• node scripts/generate-content-graph.js — gold-standard compliance rose from 5/77 to 6/77 (on this branch, base is post-Batch-A-merge only).
• npm run build — succeeds. No broken-anchor warnings involve this file.

Safety/Evidence checks:

• No therapy/diagnosis/clinical claims added.
• No citations fabricated — Gifts/Limitations sections synthesize existing in-module content rather than introducing new sources.
• No [HUMAN-REQUIRED]/[HUMAN-RECOMMENDED] sign-off sections exist in this file.

Human decisions required: None.

This is the final batch of Task #10 (9 flat-heading modules → journey template, across Batches A–D). Next up: Task #11, spot-checking the remaining ~68 modules for skeleton completeness.
