The 4948-line `server.ts` still crashes; the workaround is to never import its heavy modules (executor.ts, session/analytics.ts, session/db.ts) into the same compilation unit. + +2. **Multiple independent `node:sqlite` databases per process.** The 4 tool bundles each open their own per-pid DB at `/tmp/context-mode-*-.db` without contention. WAL mode is set on each. The `ctx_fetch_and_index` tool uses a separate DB so its writes never block the main `ctx_index`/`ctx_search` path. + +3. **`for (var k in X) tools[k] = X[k]` merge pattern works.** Used to import the 4 tool bundles (`tools as execTools`, etc.) into the main `server-http.ts` registry at module-init time. `Object.entries` + array push also works (used in `tools/list`). + +4. **Bare `catch {}` is preferred** when the error is unused (project rule, also matches Perry style). `catch (_e)` and `catch (e) { /* ignore */ }` both compile but the bare form avoids an unused-binding allocation. + +5. **`spawnSync("node", [tmpfile])` works** for sandboxed execution. The temp file is created in `mkdtempSync(tmpdir())` and always removed in a `finally` block, so even a crash inside the snippet cannot leak files. `Math.random().toString(36).slice(2, 8)` for the random suffix compiles fine. + +6. **`spawnSync` browser-open helpers work.** `xdg-open` (linux), `open` (mac), `cmd /c start ""` (windows) all return synchronously within the 5s timeout. Used by `ctx_insight` to open the dashboard URL. + +7. **No new Perry patches required.** The 5 patches already committed at `b72f6f9af` (eval_classifier, expr_new, alias_tracking, freshness, lib) cover everything the new tool bundles need.

Confirmed root cause: GC-sensitive codegen interaction that shifts when `console.error` is added at different module locations. A minimal fix would require a non-trivial change to the GC code path in `perry-codegen` (likely in the conservative-scan mode or object-shape representation). Cancelled — the incremental port approach made the fix unnecessary for this build.
