A capa foi refeita duas vezes, o deploy servia os bytes novos — e o blog continuava mostrando a imagem velha. O culpado não era o build nem o CDN: era um header que prometia que o arquivo nunca ia mudar por um ano. A história da caçada, a matemática do cache imutável e a regra que ficou: rework de asset exige URL nova.
The cover was remade twice, the deployment served the new bytes — and the blog kept showing the old image. The culprit wasn't the build or the CDN: it was a header promising the file would never change for a year. The story of the hunt, the math of immutable caching, and the rule that stuck: reworking an asset requires a new URL.
A wrong Cache-Control header in vercel.json was overriding the revalidate=1800 ISR setting and turning every cache expiry into two synchronous GitHub calls inside the TTFB. The story of how cold cache became warm: 3.6s down to 140ms.
Um header Cache-Control errado no vercel.json sobrescrevia o revalidate=1800 do ISR e transformava a expiração do cache em duas chamadas síncronas ao GitHub dentro do TTFB. A história de como o cache frio virou quente: 3.6s pra 140ms.
Arachne's vision pipeline evolved: qwen2.5vl:7b on Ollama WSL, arachne-vlm-jobs queue with arachne-vlm-w1 worker, SQLite vlm_cache.db cache (sha256), polling GET /api/extract/image-jobs/{id}. Vision requires JWT, PYTHONPATH api/ and PostgreSQL not SQLite.
O pipeline de visão do Arachne evoluiu: qwen2.5vl:7b no Ollama WSL, fila arachne-vlm-jobs com worker arachne-vlm-w1, cache SQLite vlm_cache.db (sha256) e polling GET /api/extract/image-jobs/{id}. Visão exige JWT, PYTHONPATH api/ e PostgreSQL (não SQLite).
Portfolio was 100% functional, 218 tests passing, zero CI errors. But mobile Chrome users saw old versions when restoring tabs. The cause: Chrome's bfcache ignores HTTP headers — and the fix came cross-project from LifeLog.
O Portfólio estava 100% funcional, 218 testes passando, zero erros no CI. Mas usuários de mobile Chrome viam versões antigas ao restaurar abas. A causa: o bfcache do Chrome ignora headers HTTP — e a solução veio cruzada de outro projeto.
