+## PHASE 69 — Sessão web expirando cedo demais pra call center (pedido do
+usuário: "no minimo 12 hs")
+- [x] Access token JWT (`packages/auth/src/tokens.ts`) e o teto absoluto do
+      cookie de sessão (duplicado em `login`/`post-login`/`select-tenant`
+      route handlers + `middleware.ts`) subiram de 15min/8h pra 12h. O
+      refresh silencioso do middleware (decodifica o `exp` do JWT, renova
+      via `/auth/refresh` uns 60s antes de vencer) continua existindo e
+      deslizando a sessão a cada requisição — 12h passa a ser só o teto de
+      segurança pra quando esse refresh falhar (aba parada, logout em
+      outro lugar), não o intervalo real de renovação.
+- [x] Verificado com login real: token decodificado mostra exp−iat = 12h
+      exatas.
+
+## PHASE 70 — Softphone WebRTC não registrava, ficava cinza pra sempre
+(usuário configurou o proxy QA de verdade e testou o ramal 1501 do tenant
+teste01 — "so fica cinza")
+- [x] Confirmado primeiro que a config em si estava certa
+      (`GET /platform/webrtc-proxy` devolvia a URL nova) e que a
+      infraestrutura de rede/proxy funcionava — DNS resolve, TCP conecta,
+      certificado TLS válido, e um handshake WebSocket manual (`ws`, com
+      header `Origin`) completa normal. Um REGISTER SIP cru (autenticação
+      digest manual) através do proxy chegou até o FreeSWITCH de verdade
+      (`User-Agent: FreeSWITCH-mod_sofia` na resposta) e voltou 200 OK —
+      credenciais do ramal 1501 corretas, proxy e FreeSWITCH 100% ok.
+- [x] **Achado real, bug no próprio código-fonte do widget** (não
+      descoberto antes porque a verificação da PHASE 66 só conferia se o
+      `<script data-sip-*>` recebia os atributos certos, nunca deixava o
+      widget tentar registrar de verdade contra um proxy ao vivo):
+      `widgetStorage.mergeConfig` (`src/widget/widgetStorage.js`) só
+      calculava o campo `aor` (`sip:user@domain`) no branch de config
+      SALVA MANUALMENTE (localStorage) — no branch usado quando a config
+      vem de `data-sip-*`/`window.HandphoneConfig` (nosso caso, sempre),
+      `aor` nunca era calculado. `connect()` (`useSip.js`) quebra em
+      `cfg.aor.startsWith(...)` com `aor` undefined — erro só visível no
+      console do navegador (`[Widget] Connect failed: TypeError...`),
+      nunca pro usuário, que só via o botão preso em cinza (desconectado)
+      pra sempre, sem nenhuma tentativa de conexão visível.
+- [x] Fix: `mergeConfig` agora calcula `aor` a partir de
+      `externalConfig.username`/`externalConfig.domain` também no branch
+      sem config salva. Patch na mesma cópia local do
+      `git.falehandix.com.br/Handix/handphone-2.0` já usada na PHASE 66
+      (nunca enviado pro repo externo do usuário) — rebuildado e
+      revendorizado em `apps/frontend/public/handphone.js`.
+- [x] Testado ponta a ponta com Playwright + navegador real, fora do app
+      (uma página HTML isolada com os `data-sip-*` do ramal 1501 de
+      verdade, sem depender do login do tenant): REGISTER completa com
+      200 OK observado no tráfego WebSocket real, botão do widget muda de
+      cinza pra verde (conectado).
