Five tightly-coupled fixes that were causing the interview subsystem to silently
degrade in production:
- C1+C2: `_build_orchestrator` now resolves `graph_id` from
`SimulationManager().get_simulation(sim_id).graph_id` (the real persisted
state) instead of a `graph_id.txt` that nothing in the codebase writes.
`ZepGraphMemoryUpdater(graph_id=...)` is now called with the correct
positional argument; the bare `try/except Exception` that was swallowing the
TypeError is replaced with a narrow fallback that logs explicitly.
- C3: `SimulationManager._on_ready_hooks` / `_on_completed_hooks` are now
class-level (mirroring `SimulationRunner._on_completed_callbacks`).
Hooks registered at app startup now survive across the per-request
`SimulationManager()` instances created by the Flask API, so the T0
longitudinal auto-survey actually fires.
- C4: `ZepGraphMemoryUpdater` gains an explicit `add_text_episode(graph_id, text)`
method for synchronous text writes. `InterviewZepWriter._emit` no longer
silently falls back to a dict-shaped `add_activity` call that the real
implementation rejects (its `add_activity` requires an `AgentActivity`
dataclass).
- C5: `FileSystemPersonaProvider.agent_to_entity()` builds an
`{agent_id: zep_entity_uuid}` map from the persisted profile files; the map
is now passed to `ZepMemoryProvider` so `get_entity_with_context` is called
with real Zep UUIDs instead of `str(agent_id)`. To make this work,
`OasisProfileGenerator._save_reddit_json` and `_save_twitter_csv` now persist
`source_entity_uuid` (Reddit JSON: optional field; Twitter CSV: appended
column).
Tests: 51 unit + 2 integration pass (was 40 + 2). New tests lock in each fix:
- `test_hooks_survive_across_instances` (C3)
- `test_build_orchestrator_reads_graph_id_from_state` (C1+C2+C5)
- `test_build_orchestrator_falls_back_when_state_missing` (C1+C2)
- `test_emit_uses_add_text_episode_with_graph_id`,
`test_emit_raises_when_updater_lacks_add_text_episode`,
`test_real_updater_exposes_add_text_episode` (C4)
- `test_agent_to_entity_from_reddit_json`,
`test_agent_to_entity_empty_when_no_field`,
`test_agent_to_entity_falls_back_to_twitter_csv`,
`test_agent_to_entity_reddit_takes_precedence` (C5)
