Selzler Construtora

##the_problem

The existing company domain selzlerconstrutora.com.br hosts an external legacy WordPress site not authored by Marcos. Every completed project and client record required calling a developer. The partners needed an independent platform to publish their work.

##what_it_does

• Public frontend reproducing the existing information architecture: home, about, completed works split by public/industrial/residential, works in progress, clients, contact and privacy policy.
• Admin panel behind a partner login with no public signup. Users are created by seed. Full CRUD over works and clients, with image upload.
• Client logo carousel as a continuous JetBrains-style marquee, with real logos.
• Cookie consent card gating analytics, for LGPD.
• Google Places integration for reviews, synchronised in the background by a hosted service.
• Container warm-up on the contact page, a serverless cold-start detail resolved before the visitor can feel it.

12docs/audit/2026-07, four separate sweeps

##how_it_was_built

This is the repository where the methodology is most explicit. The stack was locked by a dated decision ("locked on 14/07/2026, do not change without explicit discussion") and the structure, authentication and testing patterns were deliberately inherited from Telas Paraná. Reuse between the same author’s projects, not reinvention. The modular monolith is likewise justified rather than copied: no process split until there is a concrete reason.

The agent configuration carries a team of specialised sub-operators (architect, backend, frontend, DBA, devops, cybersecurity, DPO, QA, content and vault), each with persistent per-agent memory holding concrete lessons from the project. Those memories are behavioural corrections that outlived the session that produced them.

Work is organised as numbered PRDs (client carousel, JWT auth, frontend login, an OpenAPI vulnerability, admin hardening) plus a formal audit with four separate sweeps across backend, database, frontend and security, whose twelve findings were closed in a commit of their own.

Unusual for a project this size: a legal folder analysing software law, civil code, LGPD and the Brazilian internet framework, a map of data sub-processors, a signed DPA versioned as a PDF, and a claims audit of the site’s public statements so that no published number is invented.

##known_limitations

• Project paused on hiatus: the platform was fully developed through v0.4 and paused awaiting opportunity before replacing the legacy external WordPress domain selzlerconstrutora.com.br.
• Not deployed in production. Everything through v0.4 is complete and working locally, but production rollout remains open.
• The frontend test suite covers structural invariants, not appearance. Layout and accessibility still require direct measurement in a real browser.
• A designed next sprint exists on paper only: a local vector RAG over the documentation, exposed to the agents through an MCP server.

##roadmap

• v0.1 health check ✓
• v0.2 CRUD ✓
• v0.3 public frontend ✓
• v0.4 admin auth ✓
• v1.0 production deployment on its own domain: pending
