Query: # Fourth independent review: tool-result replay and output bound

The terminal acceptance reviewer rejected the current candidate after running
the requested tests and inspecting the production path. Continue the same
self-update and correct these exact defects without expanding scope:

1. Status is currently appended to `source_messages[-1]` / `api_messages[-1]`
   without requiring a user message. After a tool call the newest message is a
   tool result, but production replay restores `api_content` sidecars only for
   user and assistant messages. A sidecar attached to the tool result therefore
   disappears on the next request, breaking the claimed byte-identical replay.
   Make attachment and replay behavior consistent with the real persisted
   message contract. Preserve role ordering and keep clean transcript content
   unchanged.
2. `build_model_status_context()` converts the TODO `item_id` to a string
   without truncating or otherwise bounding it. Enforce a deterministic total
   output bound, including adversarially long identifiers and descriptions.
3. Add behavior-contract tests that would have caught both defects: a
   successive-request sequence whose newest message is a tool result, and an
   oversized TODO identifier. Exercise the same production helpers/type checks
   used by `conversation_loop.py`.

Run the focused tests, the existing replay/cache regression set, compilation,
and `git diff --check`. Update `BOOK_SELF_EVOLUTION_REPORT.md` with this fourth
review round and exact results. Do not edit the book, commit, push, or claim
downstream task improvement.

┌─ Reasoning ──────────────────────────────────────────────────────────────────┐
**Considering integer representation**

I'm thinking about unbounded integer representation, but I realize that maximum values
 can get huge. I might want to normalize or cap numeric displays for clarity. There
’s a need for a deterministic total that closes with truncation if it exceeds a maximum
 value, possibly with a helper function to handle this.

I also need to consider controlling IDs and whitespace sanitation, ensuring everything
 is formatted neatly. Revising and testing these current tools will help ensure the
 results fit within the expected parameters.

┌─ Reasoning ──────────────────────────────────────────────────────────────────┐
**Updating test expectations**

I need to update the test expectations for the latest durable assistant index to -
2, which involves checking the status of the closest generation for the assistant
. The existing test assertion is outdated, so I'll have to revise that. Also, I'll
 look into the second assertion regarding indices. It’s important to run the tests
 after these updates to ensure everything is functioning as expected. Let’s get this
 updated!

╭─ ⚕ Hermes ───────────────────────────────────────────────────────────────────╮
Corrected the fourth-review defects.

Changes:

- Status attachment now searches backward for the newest durable user or assistant message instead of attaching to a tool result.
- Tool-result messages remain unchanged and receive no non-durable sidecars.
- Production replay remains restricted to the persisted user/assistant sidecar contract.
- Added deterministic output bounds:
  - TODO identifier: 96 characters;
  - TODO description: 200 characters;
  - complete status block: 1200 characters, preserving </agent_status>.
- Added behavior-contract tests for:
  - a successive request whose newest message is a tool result;
  - durable sidecar attachment and replay;
  - a 100,000-character TODO identifier;
  - the shared production replay type check.

Verification:

- uv run --with pytest pytest tests/agent/test_model_status_context.py -q
  - Passed: 6 passed in 0.10s
- 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 9.37s
- 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.

BOOK_SELF_EVOLUTION_REPORT.md now includes the fourth review round and exact results. No book changes, commit, push, or downstream task-improvement claim was made.
