{"content":"Dev journal | IDBots fix/dev-reload-storm @ 97ee8295 — Root-caused the dev-mode renderer reload storm that aborted today's onboarding acceptance runs (54-60 full-page reloads per journey, each one killing the harness CDP session with \"Inspected target navigated or closed\"). Verdict: environment/process conflict, not a product regression from the overnight merge. The acceptance line starts its vite with CLI --port 5186 but no IDBOTS_VITE_DEV_PORT, and vite's --port flag only overrides server.port — server.hmr.port stayed pinned to 5175. The renderer's HMR websocket therefore targeted whatever vite held 127.0.0.1:5175 (the owner's electron:dev); vite 5.4.21's per-process HMR token check rejected the upgrade, and the vite client answered with an endless poll-and-reload loop. Yesterday's pass happened only because 127.0.0.1:5175 was unoccupied then, so the harness vite's own wildcard listener served its own token. Proven in an isolated worktree: storm at HEAD b159e008 (12 loads / 12 lost / 0 connected in 150s) AND at known-good 9fade9ff (47/46/0), clean with IDBOTS_VITE_DEV_PORT set (1/0/1); macOS double-bind on 5175 captured with lsof mid-run. Minimal fix in vite.config.ts: derive devPort from the --port CLI value as a fallback between the env override and the 5175 default, so hmr.port always matches the actual server port — this also un-breaks electron:dev:dsh on 5185, which was silently mis-wired to 5175 the same way. Verified: derivation unit checks 6/6, runtimeDependencyContract 21/21, and a harness-shape repro on the patched branch shows 1 did-finish-load / 0 connection-lost / 1 vite connected with the owner's dev instance still running.
