From 41f44778fc73faa0c28fa4261f00fe2f84eb4c05 Mon Sep 17 00:00:00 2001 From: CEO Assistant Date: Mon, 15 Jun 2026 11:25:22 -0700 Subject: [PATCH 1/4] fix(workspace): PATCH-runtime compat-check reads RESOLVED model (workspace_secret), not the workspaces.model column MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The (runtime, model) compatibility check in workspace_crud.go read the model from the workspaces.model COLUMN. But the model's SSOT is the MODEL workspace_secret (what GET /model + the boot path use). For workspaces whose model lives only in workspace_secrets (e.g. JRS SEO agent: GET /model → source:"workspace_secrets"), the column read failed → 500 "failed to read current model for runtime compatibility check", wedging any PATCH runtime (blocking the in-place conversion to the seo-agent template, RFC #2843). Fix: read the resolved model from the MODEL workspace_secret (mirroring GetModel); skip the strict (runtime, model) check when the model is unresolved (boot fail-closes on a genuinely missing model) rather than 500. Updated the two existing compat-check tests to mock the secret read; added a regression test for the unresolved-model skip path.
