1 # Architectural Strategy: Niche Localization, SSR Routing & Trust Standardization
2
3 ## 0. Documented Strategy

5 ### Executive Summary
6 The architecture balances internal flexibility with external rigidity. A **Faceted Taxonomy (Tags)** handles database filtering, while **Dynamic SSR Landing
Pages** capture long-tail SEO traffic. High-margin testing providers require **Standardized Trust Fields** (verified certifications) rather than pure
templates. Standardization is the platform's protective moat.
7
8 ### The "First Principles" Solution (Aggregate vs. Distribute)
9 To avoid Google's "doorway page" penalty from thousands of thin-content local pages:
10 1. Global Level (SSR PSEO): Create programmatic pages for the industry concept (e.g., tstr.directory/standards/iso-17025/texas). These pages list
all matching companies for maximum Information Gain.
11 2. Company Level (Mega-Profiles): A specific branch (e.g., SGS Houston) gets ONE extremely comprehensive Profile Page at /company/[slug].
Navigation uses anchor links (#certifications, #equipment).
12 3. Group Level (Parent Brands): Massive global groups (e.g., SGS) get a "Brand Aggregate Page" at /group/[slug], consolidating global certifications
and listing all local physical branches.
13
14 ### The Monetization Funnel (Trust Tiers)
15 1. Tier 1 (Aggregated - Free): Scraped public data with a "Claim this profile" CTA.
16 2. Tier 2 (Claimed - Free): User-reported data via domain-verified claiming.
17 3. Tier 3 (TSTR Verified - Premium): Manual/API verified certifications. These profiles receive the "TSTR Verified" shield, bid on incoming RFPs, and
display rich media.
18
19 ### Pricing Structure: Group vs. Single Company Economics
20 * The Mechanism: Billing is attached to the "Verified Branch" level but managed at the "Parent Group" level.
21 * Single Company: Pays a standard flat monthly fee (e.g., $99/mo) to upgrade their single /company/[slug] page to Tier 3.
22 * Massive Groups (SGS): The Parent Group claims the /group/[slug] page and manages all branches. We charge a tiered volume discount (e.g., 1-10
branches at 100%, 11-50 at 75%, 51+ at 40%).

26 ## 1. Codebase Analysis & Required Changes
27
28 ### Supabase Changes
29 Current State: listings table has parent_listing_id. listing_capabilities has verified fields.
30 Required Updates:
31 - RLS Security: Create a strict Row Level Security policy ensuring only authenticated TSTR Admins can update verified = true on
listing_capabilities.
32 - Group Query View: Create a Postgres View or RPC function that efficiently aggregates all child branches and their combined capabilities for a given
parent_listing_id to feed the /group/[slug] pages.
33
34 ### Cloudflare Pages Changes
35 Current State: Astro is configured for SSR (output: 'server'), running on Cloudflare Pages Functions.
36 Required Updates:
37 - Edge Caching: Because we are using SSR for millions of potential route intersections (Category × Standard × Region), we must implement strict
Cache-Control headers (e.g., s-maxage=86400, stale-while-revalidate) in our Astro API responses so Cloudflare caches these dynamic routes at the Edge,
preventing Supabase database exhaustion.
38
39 ### Astro Frontend Changes
40 Current State: Routing handles /[category]/index.astro and /[category]/[region]/index.astro via SSR.
41 Required Updates:
42 - Expand SSR Routing: Create src/pages/[category]/[standard]/[region]/index.astro.
43 - Create Profile Routes: Build src/pages/company/[slug].astro (Mega-Profile) and src/pages/group/[slug].astro (Brand Aggregate).
44 - Compliance Matrix Component: Build a strict UI table component mapping verified standards (from listing_capabilities) with visual badges for Tier 3
verified profiles.

48 ## 2. Recommended Agent Implementation Workflow
49
50 According to AGENTS.md rules, hand off execution in this exact order:
51
52 1. Database Refinement (Supabase SQL)
53 - Agent: ask-code or omg-executor
54 - Task: "Write a Supabase migration to enforce the parent_listing_id hierarchy. Lock down RLS for the verified flags on capabilities. Create an
RPC function to aggregate child branches for Group pages."
55
56 2. Frontend Architecture (Astro SSR & Edge Caching)
57 - Agent: omg-executor
58 - Task: "Implement the new SSR routing structure (/group/[slug], /company/[slug], /[category]/[standard]/[region]). Implement Cloudflare Edge
Cache-Control headers to protect Supabase from dynamic route spam."
59
60 3. UI / Component Development
61 - Agent: ask-gemini
62 - Task: "Build the 'Compliance Matrix' and the long-scroll 'Mega-Profile' layout utilizing Tailwind CSS. Ensure Tier 3 verification badges are
prominently displayed."
63
64 4. Data Population (Python Scrapers)
65 - Agent: qwen
66 - Task: "Update the Python scrapers in /web/tstr-automation/ to identify Parent companies vs Branches, and populate the parent_listing_id
accordingly."
