Remove the Classroom tier — Tappymaps is not a school product

[mapzimus]

Re-opened from #44, which merged at dd0d331 and captured only the app_admins migration — this commit was pushed to the same branch but landed outside the merge snapshot. Same thing happened between #43 and #44.

Important

This is time-sensitive. The database half of this change is already applied to production: classroom_codes and classroom_lookup() are dropped and has_subscription('classroom') returns false for everyone. Until this merges, the live site still shows a Classroom tier that the database no longer backs — "Get Classroom" would run a real Stripe checkout for a tier that grants nothing, and /class/:code errors. Merging this closes that gap.

What this removes

Tappymaps is not a school product. The $12/mo Classroom tier — class codes, printable worksheet packs, a /class/:code route — framed it as one, so it comes out in full rather than hiding behind a flag.

Checked before removing anything destructive: production held 0 rows in classroom_codes and 0 subscriptions at tier classroom. Nobody loses access and no paying customer is affected.

App (index.html, −497 lines)

• Deleted the Classroom tools + upsell blocks in the Create Upgrade panel, their CSS, and the upgrade modal's Classroom button.
• Deleted the class-code / worksheet subsystem: code mint / copy / join, the classroom_lookup RPC call, exportWorksheetPack, Modes.ClassJoin and its route, and wireClassroomUI.
• Collapsed entitlements to one paid tier — dropped appState.classroomUnlocked, isClassroom(), startClassroomCheckout(), updateClassroomUI(). Owner accounts auto-grant pro.
• Rebuilt /pricing as Free vs Pro (was Pro vs Classroom-for-teachers) and dropped the "Have a class code?" join box.
• Dropped "high-school math teacher" from the About bio.

Billing handlers

• create-checkout no longer resolves a classroom plan or reads STRIPE_CLASSROOM_MONTHLY_PRICE_ID.
• verify-subscription drops isClassroom from its payload; tier is pro | free.
• webhook's tierForPrice always resolves 'pro'. The indirection stays so a future second tier is a one-line change rather than a migration.

Database — supabase/migrations/20260822_remove_classroom.sql, already applied to production

• Dropped classroom_lookup(text) and classroom_codes (taking its two RLS policies with it).
• Redefined active_subscription_tier() so admins get 'pro', and has_subscription() without the classroom-implies-pro special case.
• Re-asserted the schema v2 grant posture on both redefined functions.

Verified by JWT impersonation after applying:

max@mapparatus.org     tier=pro     has('pro')=true   has('classroom')=false
mhowe.gis@gmail.com    tier=pro     has('pro')=true   has('classroom')=false
random authenticated   tier=(none)  has('pro')=false  has('classroom')=false

classroom_codes dropped: true    classroom_lookup dropped: true
stray classroom rows: 0          policies mentioning classroom: 0

Guardrails

checkout-plan-smoke now asserts that classroom / teacher / worksheet / class-code wording cannot reappear in index.html or the checkout handler, and CLAUDE.md records the constraint so a later session does not rebuild it.

Map subject matter is deliberately untouched: a Census Bachelor's Degree+ dataset, or a GeoDraft backlog category like "high school graduation rate", is ordinary demographic data rather than school framing. None of those backlog categories are wired into the app today.

Verification

Re-run on the rebased base (007221d):

• npm run validate — both blocks pass; Block 1 unchanged at 34,471 chars
• node --test test/*.test.mjs — 18/18
• node scripts/api-subscription-test.mjs — 16/16
• node scripts/checkout-plan-smoke.mjs — pass, including the new negative guards
• npm run smoke — all checks pass, zero console errors
• /pricing and the Create Upgrade panel inspected in a real browser

Note for whoever touches billing next

Every write to user_subscriptions must keep setting tier. The database cannot read Stripe price IDs, so a row written without it locks a paying customer out at the RLS layer even though checkout succeeded.
