Change

Fixes #2028. While agy is working its conversation database has a live -wal/-shm pair, so agyCatalog copies it into mkdtempSync(join(tmpdir(), ...)) and opens the copy with SQLITE_OPEN_NOFOLLOW. On macOS tmpdir() is /var/folders/.../T and /var is a symlink, so SQLite fails with SQLITE_CANTOPEN_SYMLINK and Chat falls back to Terminal for the whole turn. The snapshot directory is now resolved with realpathSync before use. Linux is unaffected (its tmpdir is normally not behind a symlink).

Validation

• bun test server/agy.test.ts on macOS (Apple silicon, Bun 1.4.4): on main, reads a WAL catalog with null missing without changing side files fails with Agy history is unavailable; with this change 11 pass, 0 fail. CI runs Linux only, which is why the existing test did not catch it.
• Live check against Antigravity CLI 1.4.7: during a working turn /api/pane/conversation returned agy-transcript 26/26 times (before: scrollback for the whole turn).
• bun run test:unit locally also shows failures in integrations-routes, plan-routes, http and scripts/plugin tests; they fail identically on unmodified main in this environment and are unrelated.

Explanation

[ #2028 ] server/agy.ts now applies realpathSync to the directory returned by mkdtempSync before it builds and opens catalog.db. This removes the macOS /var symlink from the SQLITE_OPEN_NOFOLLOW path. The reported macOS test passes with this change, and the existing WAL snapshot behavior remains in place.

Verified at b7702ea, rebased locally onto current main without conflicts. server/agy.test.ts passes 11/0. A WAL catalog read with TMPDIR behind a symlink (the macOS /var case, on Linux) returns the catalog with this change and fails with "Agy history is unavailable" when only the fix is reverted.

I pushed 4c7d6ea for CodeRabbit's cleanup finding: the snapshot path is assigned before realpathSync, so a failed resolve still removes the directory. The thread is answered and resolved. On that head, bun run check fast passes (exit 0, 7,294 pass / 0 fail / 24 skip), the agy tests pass 11/0, and the symlink probe still passes. Not run on a real Mac here. Thanks, @phlips5437.

Merge pass review report. Overall: PASSED. This outside contribution from @phlips5437 opens the agy catalog snapshot through its real path on macOS. The maintainer approved the merge, and the gate (omo-native-gate-reviewer, gpt-6-astra) passed it.

Gate verification:

• A fixture with a symlinked tmpdir and a WAL file passes with the patch and fails on the baseline.
• Symlinks for the database, WAL and SHM that point outside the store are still rejected.
• The agy tests pass 11/11, and typecheck passes.
• The unit suite passes on top of main: 7423 tests, 0 failures.
• The lane's commit 4c7d6ea addressed the CodeRabbit cleanup thread, and the thread is resolved.

A maintainer adds the changelog credit when the release folds the fragments (changelog.d/README.md).
