Track curriculum migration: move source content into repo and align 3-course model

[projectamazonph]

Goal

Turn AMPH from a platform with imported lesson text into a current, job-ready Amazon PPC training product, per docs/CONTENT-AUDIT-2026-07-16.md and docs/CURRICULUM-REDESIGN.md.

Reference docs (already in docs/)

• docs/CONTENT-AUDIT-2026-07-16.md - critical P0/P1 issues + release plan
• docs/CURRICULUM-REDESIGN.md - target 3-course model, module map, assessments, production order
• docs/VIDEO-EXPLAINER-SCRIPTS.md - 8 Foundations video scripts
• docs/0-1-welcome-to-amph.md - Module 0 lesson 1 (sample)
• docs/1-1-read-ppc-data-before-you-change-it.md - Module 1 lesson 1 (sample)
• docs/CONTENT-UPDATE-PLAN.md - Release 1 file-by-file execution plan (new)

Release 1 - Trust and safety

• Move curriculum source into content/curriculum/ (stop reading from hard-coded Android path in scripts/import-amph-content.ts) - P0 (PR fix(content): version curriculum source in the repo, drop Android path #26)
• Replace legacy product/feature references (AdCraft, AI Mentor, Formula Calculator, wrong simulator names) - P0
• Correct factual claims: portfolios, attribution windows, auction/CPC, listing quality score, dayparting - P0
• Align three pricing tiers with access rules and actual content - P0 (code side done; see notes)
• Add factual-review metadata (Amazon Ads Fact Card) to time-sensitive lessons - P0

Release 2 - Foundations that lead to action

• Rewrite foundation + campaign-building lessons using the lesson-production standard
• Ship short video explainers + matching practice sheets
• Add calculation, keyword-map, and campaign-rationale artifacts with rubrics

Release 3 - Operator and client readiness

• Build advanced optimization, reporting, client-delivery modules
• Add rubric-based assessments + portfolio capstone
• Add human-review workflows for Ultimate learners

Notes

• This issue tracks content work only. Code-side blockers (renderer cannot show tables/ordered lists/links/images/video) are called out in the audit and should get their own issue if not already present.
• Release 1 is code/content complete as of the work described in the comments below. Two follow-ups before the pricing-tier item is fully done end-to-end: (1) the fact cards' Last verified/Next review due/Owner fields are placeholders for the content owner to fill in, and (2) the new two-course split in scripts/import-amph-content.ts has not been run against a real database yet — verify against a non-production DB first.

Release 1 ("Trust and safety") is done. Summary:

Plan: docs/CONTENT-UPDATE-PLAN.md — file-by-file work order for every remaining P0, with exact lines and required-replacement text pulled from the audit.

Legacy references removed: AdCraft, AI Mentor, Formula Calculator, and "STR Triage Arena" purged from onboarding + module 4/6/7 practice-prep lessons. Replaced with the real platform (4-tab nav, 5 named tools).

Five factual corrections + fact cards, one per claim in the audit's table:

• Portfolios don't carry shared negatives/bid adjustments (campaign-level controls)
• Attribution windows aren't a fixed 7-day SP / 14-day SB rule — taught as an account setting to verify
• Auction isn't a simple "$0.01 above next bid" mechanic — reframed around bid ceiling + monitoring realized CPC
• "Listing Quality Score" reframed as "listing and ad relevance signals" (teaching shorthand, not a real inspectable metric)
• Dayparting qualified as eligibility-dependent, with a manual fallback

Course/tier split: scripts/import-amph-content.ts now creates two Course rows (ppc-foundations = modules 0-4, accelerated-mastery = modules 5-8) instead of one course tied to a single tier — matches the existing Course.pricingTierId schema, no migration needed. ultimate-transformation intentionally still has no course (its modules don't exist yet — Release 3).

Two things still need a human before this is fully closed out:

1. The fact cards' Last verified / Next review due / Owner fields are placeholders — need the content owner to fill in.
2. The course-split script has been reviewed by hand but not run against a real database (no DATABASE_URL in this session). If this importer has ever run against production before, the module 5-8 slug prefix changed (amph-foundations-* → accelerated-mastery-*) — reconcile old rows before re-running for real.

Full detail in SESSION-HANDOVER.md's "Content track: Release 1 plan + execution" section. Next up is Release 2 (full lesson rewrites to the 10-block production standard) per docs/CURRICULUM-REDESIGN.md.
