+
+# Testing the opencodex management API locally
+
+## Start a scratch instance
+- `OPENCODEX_HOME` relocates OpenCodex-owned state ONLY (config.json, admin-api-token,
+  lab automation state, SQLite projections). Client homes are NOT relocated: startup
+  syncs can still write to the real `~/.codex`, `~/.grok`, `~/.claude`, and Claude
+  Desktop dirs. Point these at scratch too: `CODEX_HOME`, `GROK_HOME`,
+  `CLAUDE_CONFIG_DIR`, `OPENCODEX_CLAUDE_DESKTOP_CONFIG_DIR`.
+- `codexAutoStart:false` does NOT gate startup client syncs: `shouldSyncCodexOnStart`
+  reads `clientIntegrations.codex` (absent = ON), `shouldSyncGrokOnStart` reads
+  `clientIntegrations.grok`, and the Claude roster write (`ocx-*.md` into
+  `~/.claude/agents/`) is gated by `claudeCode.enabled`/`claudeCode.injectAgents`.
+  Observed: a run with only OPENCODEX_HOME + codexAutoStart:false still injected five
+  `ocx-*.md` files into the real `~/.claude/agents/`.
+- Safe scratch `config.json`:
+  `{"port":<testport>,"hostname":"127.0.0.1","codexAutoStart":false,
+   "clientIntegrations":{"codex":false,"grok":false,"claude-desktop":false},
+   "claudeCode":{"injectAgents":false}}`
+  — loopback bind avoids the server-auth assert. Use the env vars AND the config
+  disables together; either alone leaves a write path open (e.g. a disabled
+  integration still prunes its owned files under the real home).
+- Residual writes the recipe does NOT cover (macOS only, opencodex-owned artifacts
+  only): startup always runs `refreshOwnedRaycastCatalog` (rewrites an existing
+  opencodex-owned Raycast provider entry under the OS home — no env override) and
+  `reconcileShellHook` (removes the opencodex-marked block from `~/.zshrc` when the
+  system env is inactive — `CLAUDE_CONFIG_DIR` does not redirect it). Harmless on a
+  box with neither installed; for hermetic isolation on macOS run under a disposable
+  OS user/home instead.
+- Management auth: set `OPENCODEX_ADMIN_AUTH_TOKEN` (any non-empty string works for the env
+  source). If unset, the server mints `admin-api-token` in OPENCODEX_HOME on first start.
+- Start foreground: `bun run src/cli/index.ts start --port <testport>`
+  (`bun run dev` is the same). bun is not on PATH — prefix `PATH="$HOME/.bun/bin:$PATH"`
+  in Git Bash. `ocx ensure`/tray paths spawn DETACHED children instead — avoid them for testing.
+
+## Calling /api/*
+- Header: `x-opencodex-api-key: <token>` (or `Authorization: Bearer <token>`). No token →
+  `401 {"error":"opencodex admin token required"}`. Origin header NOT required for curl.
+- Useful routes: `GET/PUT /api/lab/automation` (status has `schedulerRunning` — live
+  interval presence, not just policy), `POST /api/lab/automation/run` (SYNCHRONOUS — the
+  200 response IS the terminal run record), `GET /api/lab/automation/runs`.
+- PUT policy body: `{"policy":{"enabled":true,"layers":{"protocolConformance":true}}}`;
+  merges with disk policy atomically.
+- Manual run body: `{"evidenceLayer":"protocol_conformance","scenarioId":"responses-core.protocol.request-shape"}`
+  — protocol_conformance runs need NO provider (in-process fixture harness; upstream is
+  deliberately dead). live_route_compatibility needs providerName+modelId in config.
+- Scheduler tick is `LAB_AUTOMATION_HARD_MAX.schedulerTickMs` = 60s — scheduled work only
+  appears in `/runs` after the first tick; runs persist to `<OPENCODEX_HOME>/lab/automation-state.json`.
+
+## Windows desktop quirks
+- The exec tool CANNOT spawn visible desktop windows (`cmd //c start` hangs the shell on
+  the inherited pipe). Open interactive windows via the computer tool: `super+r` →
+  `cmd /k <batch>` → Enter; snap halves with `super+Left/Right`.
+- Ctrl+C on a cmd batch shows `Terminate batch job (Y/N)?` — the child process still
+  received SIGINT and drains normally; answer `N` to keep the window and see the exit.
+- Single Ctrl+C → `🛑 Shutting down opencodex proxy...` → drainAndShutdown
+  (`shutdownTimeoutMs` default 5000) → exit 0. A second signal >500ms later force-exits.
+
+## Devin Secrets Needed
+- none — the admin token is provisioned by the tester via env var.
