Greptile Summary

This PR adds an ARM (ubuntu-24.04-arm) runner to the GitHub Actions test matrix and guards the sqlite-vec-dependent tests so they are skipped on aarch64 (where the wheel ships a 32-bit binary) and on macOS (where the extension fails to load in CI).

• The CI matrix now targets ubuntu-24.04-arm with Python 3.14, and the OS condition checks are updated from exact string equality to startsWith(...) to match both ubuntu-latest and ubuntu-24.04-arm.
• A new _no_sqlite_vec() helper and skipif_no_sqlite_vec marker are added to the root conftest.py, and the same skip logic (duplicated inline) is applied imperatively inside the sqlite_store and sqlite_spy_session fixtures for tests that don't use the class-level marker.

Confidence Score: 5/5

The changes are safe to merge — they add a new CI runner and skip guards for a known-broken native extension on ARM, with no changes to production logic.

The CI matrix expansion is straightforward and correctly uses startsWith to match both Ubuntu runner variants. The sqlite-vec skip logic is applied consistently through both the marker system (collection-time) and imperative fixture skips (runtime), correctly isolating only the sqlite-vec tests. The duplication of the skip predicate across three files was already noted in a prior review thread and does not represent a new defect here.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/ci.yml	Adds ubuntu-24.04-arm to the matrix with Python 3.14, changes OS values to full runner names, and updates OS conditional steps to use startsWith for broader matching.
dimos/conftest.py	Adds _no_sqlite_vec() helper and registers/handles the skipif_no_sqlite_vec marker through the standard pytest_collection_modifyitems hook.
dimos/memory2/conftest.py	Adds _SKIP_SQLITE_VEC flag (duplicates root conftest logic) and imperatively skips the sqlite_store fixture on aarch64/macOS.
dimos/memory2/test_registry.py	Adds skipif_no_sqlite_vec marker to TestRegistryStore, TestStoreReopen classes and two individual test methods that open SQLite/sqlite-vec stores.
dimos/memory2/test_store.py	Adds _SKIP_SQLITE_VEC flag, imperatively skips sqlite_spy_session fixture, and marks TestStandaloneComponents with skipif_no_sqlite_vec.

actually @Dreamsorcerer "skip if no sqlite vec" is a bit unclear on where this happens,

can we have standardized skip tag per OS? like this would have skip_arm tag? so that we know which OS can cover which functionality

We can, but this needs to be skipped in macos, so I was merging this skip. Can change to adding 2 skip markers if you prefer?

[leshy]

don't want to block too much on details, can move and reassess, but yeah generally a preferece for per-os ignores on tests, since then we can easily see our support per OS, could we fix in the follow ups?
