Hongming Wang 899a2231d6 test(platform_auth): module-functions signature snapshot drift gate ... Pin the 5 public functions adapters and the runtime hot-path import through ``from platform_auth import``: - ``auth_headers`` — every outbound httpx call merges this in - ``self_source_headers`` — A2A peer + self-message header builder - ``get_token`` — main.py reads on boot to decide register-vs-resume - ``save_token`` — main.py persists the platform-issued token - ``refresh_cache`` — 401-retry path drops in-process cache (#1877) A grep across workspace/ shows 14+ runtime modules import these: main.py, heartbeat.py, a2a_client.py, a2a_tools.py, consolidation.py, events.py, executor_helpers.py (3 sites), molecule_ai_status.py, builtin_tools/memory.py (3 sites), builtin_tools/temporal_workflow.py (2 sites). Renaming any of the five (e.g. ``auth_headers`` → ``bearer_headers``) makes every one of those imports raise ImportError at workspace boot — the failure surface is deep in heartbeat init, nowhere near the rename site. Same drift class as the BaseAdapter signature snapshot (#2378, #2380), skill_loader gate (#2381), runtime_wedge gate (#2383). Reuses the ``_signature_snapshot.py`` helpers shipped in #2381. Defense-in-depth: ``test_snapshot_has_required_functions`` asserts the five names are still present, so removing one even with a synchronized snapshot edit forces an explicit edit here with a justification. ``clear_cache`` is intentionally NOT in the snapshot — it's a test-only helper. Production code MUST NOT depend on it. Verified red on deliberate rename: ``auth_headers`` → ``bearer_headers`` produces a clean diff of the missing function in the failure message.
