Query: # Third independent review: persistence boundary

The second correction still overclaims multimodal support. Inspection of the
actual persistence boundary found:

- `hermes_state.py` types `api_content` as `Optional` and writes non-string
  values as `None` (around lines 5632–5750 and 6078–6106);
- `run_agent.py` discards non-string `_row_api_content` during flush (around
  lines 2104–2110);
- `agent/turn_context.py` exposes string-only sidecar helpers.

Thus a list sidecar is replayed within the in-memory loop but disappears after
persistence/resume, invalidating the claimed durable byte stability. Make the
smallest compatible correction: fail closed for non-string content and do not
attach the model status on unsupported multimodal/list messages. Do not widen
the database schema or persistence contract in this experiment.

Update tests to assert list, empty, mapping, and numeric values are rejected by
the same production helper, and that string sidecars remain stable across
three requests. Remove any multimodal-support claim from code comments and the
report. Run the focused tests, the existing replay/cache regression set,
compilation, and `git diff --check`; update the report with exact results.

Do not edit the book, commit, push, or claim downstream task improvement.

**Inspecting tools and current status**

I need to take action and inspect the exact current status. Also, I should note if
 the user's required skills are already loaded, and whether I need to reload relevant
 ones before replying. Maybe the answer is yes or no? We've done this in previous
 turns, but each task requires scanning for skills and loading them again. I'll make
 sure to address this before proceeding further.

**Inspecting syntax tests**

I need to take a closer look at the syntax tests. It's important to ensure everything
 is working as it should. I want to check for any errors or issues that could be lurking
. I'll go through the tests carefully, verifying each part and making sure to understand
 what may have gone wrong. OK, here we go—I'm ready to dive in and see what I can
 find!

╭─ ⚕ Hermes ───────────────────────────────────────────────────────────────────╮
Corrected the persistence-boundary issue.

Changes:

- replay_api_content_sidecar() now supports only non-empty strings.
- List/multimodal content, empty strings, empty lists, mappings, numbers, and other unsupported values fail closed.
- agent/conversation_loop.py uses the same production helper for sidecar replay and no longer claims or attempts durable multimodal support.
- Removed multimodal-support claims from comments, tests, and the report.
- Tests now verify:
  - string sidecars remain stable across three requests;
  - list values are rejected;
  - empty values are rejected;
  - mappings and numeric values are rejected;
  - the test replay helper uses the production type contract.

Verification:

- uv run --with pytest pytest tests/agent/test_model_status_context.py -q
  - Passed: 4 passed in 0.09s
- uv run --with pytest pytest tests/agent/test_api_content_sidecar.py tests/run_agent/test_background_review_cache_parity.py tests/agent/test_turn_context.py -q
  - Passed: 36 passed in 9.35s
- python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py
  - Passed.
- git diff --check
  - Passed.

The report now includes the third independent review round, exact results, the persistence-boundary rationale, and explicitly makes no multimodal-support or downstream-task-improvement claim. No book changes, commit, or push were made.
