Real LLMs (observed with anthropic/claude-haiku-4-5 on a 23-agent run)
sometimes return Likert values as JSON strings ('3' not 3). The 4 subagent
validators rejected this with isinstance(v, int), losing ~30% of agents at
N=23. Added a shared coerce_int helper in base.py that accepts ints and
numeric strings, rejects bools/floats/garbage, and is now used by:
- Longitudinal: response values 1-5
- Diversity: Q-sort placements -3..+3 and 6 Likert axes 1-7
- Delphi: R2 and R3 importance/plausibility 1-5
- Scenario: 4 dimensions 1-7
Validators now coerce in place so downstream code sees ints regardless of
the wire format. Added 8 tests (4 unit on coerce_int + 4 per-subagent
contract tests showing stringified values are accepted).

Adds SchemaValidationFailure exception carrying both retry attempts' raw
output, so audit.jsonl preserves what the model actually said when an
agent's response can't be coerced into the instrument schema. Lets us
diagnose persona-vs-format failures without re-running. Two new tests.

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)

- Add backend/app/services/interviews/lifecycle.py with install_hooks() that
registers on_ready (pre-survey) and on_completed (post-survey + synthesis)
daemon-thread callbacks on a SimulationManager.
- Add SimulationRunner.register_on_completed() / _fire_on_completed() so
external callbacks can be notified when _monitor_simulation transitions to
COMPLETED (both exit-code-0 path and simulation_end event path).
- Wire both in app/__init__.py: create singleton SimulationManager, install
lifecycle hooks, and register its _notify_on_completed with SimulationRunner.
- Add test_lifecycle.py: verifies install_hooks registers one callable for each
of ready and completed.
- All 40 unit tests + 2 integration tests pass.

Add /api/interview blueprint with POST pre/post/rerun, GET status/results/synthesis/export.csv endpoints. Background tasks tracked by UUID in module-level dict. Add register_blueprints() helper to api/__init__.py and wire app factory through it. Add UPLOADS_DIR to Config with env-override default.
