+# Book-Driven Self-Evolution Report
+
+## Run identity
+
+- Starting commit: `85c8956ec7f2b4607509980794995e1c5e21e292` (the pinned HEAD before edits).
+- Model/provider: `openai/gpt-5.6-luna` / `openrouter`.
+- Book audited: English edition under `/home/ubuntu/ai-agent-book/book-en/`; all ten `chapter1.md`–`chapter10.md` files were inspected with section-heading and targeted-term searches, followed by section-level reads. The book repository was not modified.
+
+## Four-claim audit
+
+| Reader claim | Book evidence | Hermes evidence | Disposition |
+|---|---|---|---|
+| Product-level ablation infrastructure | Chapter 1, “Harness Engineering” (lines 149–157), defines remove-one-component experiments; Chapter 6, “Ablation Infrastructure” (lines 662–706), calls for feature flags, fixed baselines, A/B methodology, and privacy-aware analytics. | Hermes has many config gates and operational telemetry, e.g. `hermes_cli/config_defaults.py` (`display.verify_on_stop`, `display.file_mutation_verifier`, `memory.write_approval`, `curator.*`), trajectory saving in `run_agent.py:2274–2292`, and evaluation/observability hooks, but no product-level campaign runner that holds a task set/model fixed and compares one disabled feature at a time. | **Absent** as a cohesive product capability; deferred. A campaign runner would be a larger evaluation product, not a safe incidental core feature. |
+| Model-visible Agent Status Bar | Chapter 2, “Agent Status Bar” (lines 787–817) distinguishes model-visible state from the human terminal bar and requires placement at context end; lines 819–835 give the structured `<agent_status>` example. Chapter 9, lines 233–239, also uses it as an inter-agent text channel. | Human-facing lifecycle/status plumbing exists in `run_agent.py:937–975`, `agent/display.py`, `hermes_cli/status.py`, and tests such as `tests/cli/test_cli_status_bar.py`; the model prompt is cached in `agent/turn_context.py:613–617`, while request-local API messages are built in `agent/conversation_loop.py:1488–1614`. Before this change there was no model-visible aggregate status block. | **Partly present**. Implemented the smallest compatible slice: opt-in request-local `<agent_status>` with API-call budget and active todo state. |
+| Forgetting/consolidation for persistent memory | Chapter 3, “Memory Compression and Organization Mechanisms” (lines 236–260), requires organization and privacy; Chapter 8, “Sleep Learning: Consolidation, Forgetting, and Capability Maintenance” (lines 297–320), requires offline batch consolidation, conflict handling, expiry/archive/delete with provenance and rollback. | Bounded memory is configured in `hermes_cli/config_defaults.py:1578–1602`; provider orchestration is in `agent/memory_manager.py`; background memory/skill review is in `agent/background_review.py`; Skill usage/staleness/archival is handled by `agent/curator.py`. These are real controls, but Curator is for agent-created Skills and bounded `MEMORY.md` is not a general evidence-backed memory consolidator with conflict resolution/retention evaluation. | **Partly present**, with the missing general mechanism intentionally deferred. Extending it safely needs provider-specific semantics, provenance, retention/transfer sets, and approval/rollback design; blindly deleting memory would violate safety and user expectations. |
+| General proposer-reviewer with independent execution-grounded verification | Chapter 1, lines 247–281, defines Verify/Correct; Chapter 5’s coding-harness material and Chapter 10, “Peer Collaboration Pattern” (lines 290–318), require a reviewer to obtain new execution/render/tool evidence, not merely reread text. | Hermes already has execution-grounded file mutation verification (`run_agent.py:3342–3465`), verify-on-stop and bounded `pre_verify` continuation (`agent/conversation_loop.py:6840–6959`), plugin `pre_verify` hooks, approval gates, background review (`agent/background_review.py`), and delegation (`tools/delegate_tool.py`). There is no universal artifact contract and no always-on independent proposer/reviewer workflow. | **Partly present**, and the proposed generic always-on mechanism is **intentionally deferred/incompatible as a default**: it would add cost/core surface and could duplicate existing verification. Use artifact-specific plugins/workflows when a concrete verifier exists. |
+
+## Change made
+
+Added an opt-in model-visible status bar:
+
+- `agent/model_status_context.py` renders a bounded, deterministic `<agent_status>` block containing API-call budget and active todo information. It ignores completed tasks and arbitrary extra fields. Its persistent sidecar helper appends only to the newest request message and stores the resulting wire content in `api_content`.
+- `agent/agent_init.py` reads `display.model_status_bar` (default false).
+- `hermes_cli/config_defaults.py` documents `display.model_status_bar: false`.
+- `agent/conversation_loop.py` appends status only to the newest API request copy and persists that exact wire content in the existing `api_content` sidecar. On later requests, historical sidecars are replayed unchanged, while the newest status is appended only to the newest message. Clean transcript content, roles, and the cached system prompt remain unchanged.
+- `tests/agent/test_model_status_context.py` adds behavior-contract tests for formatting, active-task selection, field isolation, and three successive request builds with byte-identical replay of all earlier wire messages.
+
+Deliberately rejected/deferred:
+
+- No always-on status bar: it costs tokens and is therefore opt-in.
+- No mutation of `MEMORY.md`/external providers: the evidence supports a larger consolidation lifecycle, not an unsafe delete/merge heuristic.
+- No generic proposer-reviewer core tool or mandatory second model: existing execution-grounded gates cover concrete paths; a universal reviewer needs a typed artifact/verifier contract and a campaign showing benefit.
+- No ablation runner in this change: it needs fixed datasets, outcome metrics, isolation, privacy/telemetry policy, and feature-flag control across surfaces.
+
+## Verification
+
+Exact commands run:
+
+1. `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py`
+   Result: exit code 0; compilation succeeded.
+2. `python3 - <<'PY' ... from agent.model_status_context import build_model_status_context ... PY`
+   Result: exit code 0; printed the expected block:
+   `<agent_status>`, `API calls: 3/10`, `Active tasks: 1 (in progress: 1)`, `Next active task: b — run tests`, `</agent_status>`.
+3. `scripts/run_tests.sh tests/agent/test_model_status_context.py -q`
+   Result: **blocked**, exit code 1. The repository runner reported no virtualenv containing pytest (`.venv` exists but has no pytest; no `venv`/`HERMES_PYTHON` fallback). No test result was fabricated.
+4. `uv run --with pytest pytest tests/agent/test_model_status_context.py -q`
+   Result: **passed**, `2 passed in 0.07s` (the isolated behavior-contract tests ran successfully through uv).
+5. `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py && git diff --check`
+   Result: **passed**, exit code 0; no whitespace errors.
+
+The repository wrapper was blocked by its environment lacking pytest, but the focused tests did execute and pass through `uv run --with pytest`. Existing tests were not weakened, and no approval, validator, or safety threshold was changed.
+
+## Independent review round
+
+The first candidate was rejected because it rewrote previously sent request bytes when adding each new status. This round corrected that defect by using persistent `api_content` sidecars and added three-request replay coverage. The reviewer’s scope was not expanded: no ablation campaign, memory consolidator, or generic reviewer loop was added.
+
+## Review-round verification
+
+Exact commands and results for the correction:
+
+- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `3 passed in 0.07s`.
+- `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 9.51s`.
+- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py` — **passed**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+The focused replay test proves that each earlier request message remains byte-identical in later request constructions and that the newest status is attached to the newest message. These are wire-construction tests, not an end-to-end provider run.
+
+## Second independent review round
+
+The second review found that the replay test helper accepted list-valued sidecars more broadly than the production request builder, which only replayed non-empty strings. The correction now centralizes the production type contract in `replay_api_content_sidecar()` (`agent/model_status_context.py`) and uses it in `agent/conversation_loop.py` for both current-turn and historical replay. Only non-empty strings are supported; lists/multimodal content, empty strings, mappings, numbers, and other unsupported values fail closed because Hermes persists `api_content` as an optional string. The tests call this same helper and cover string, list, empty, and unsupported values.
+
+Exact commands and results for this review round:
+
+- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `5 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**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+The review correction validates the production replay type check rather than using a more permissive test-only reconstruction. No book files were changed, and no downstream task improvement is claimed.
+
+## Third independent review round
+
+The third review found that list-valued sidecars were only safe in the in-memory request builder, not across Hermes’ persistence boundary: `hermes_state.py` and the flush path in `run_agent.py` persist `api_content` as an optional string, and `agent/turn_context.py` exposes string-only sidecar helpers. The correction therefore fails closed for every non-string content value and does not attach model status to unsupported multimodal/list messages. No database schema or persistence contract was widened.
+
+Exact commands and results for this review round:
+
+- `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**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+No multimodal support is claimed, and no downstream task improvement is claimed.
+
+## Fourth independent review round
+
+The fourth review found two production-path defects. First, status was being attached to the newest tool result even though Hermes persists and replays `api_content` only for user/assistant messages. The attachment helper now searches backward for the newest durable user/assistant message, leaving tool results unchanged; the production replay path remains restricted to those roles. This preserves role ordering, clean transcript content, and durable sidecar replay. Second, TODO identifiers were not bounded. `build_model_status_context()` now caps identifiers at 96 characters, descriptions at 200 characters, and the complete rendered block at 1200 characters while retaining the closing tag.
+
+New behavior-contract tests cover a successive request whose newest message is a tool result, confirm the sidecar is attached to the latest durable message and replays unchanged, and verify a 100,000-character TODO identifier cannot exceed the output bound. They call the same production replay helper used by `conversation_loop.py`.
+
+Exact commands and results for this review round:
+
+- `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**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+No downstream task improvement is claimed.
+
+## Fifth independent review round
+
+The fifth review identified a realistic tool-loop placement failure: assistant tool-call messages commonly have `content=None`, followed by a string tool result. Searching backward for a durable assistant then failed closed, and text-bearing assistant messages would place status before the newest tool evidence. The durable correction now targets the newest message directly. String `api_content` sidecars are persisted and replayed for `user`, `assistant`, and `tool` roles; unsupported values still fail closed, and clean transcript content and role/tool-call ordering are unchanged. When the newest message is a tool result, status is appended after that evidence, closest to generation.
+
+The focused successive-request test now uses assistant tool-call messages with `content=None` followed by string tool results across three requests. It asserts historical wire equality, status placement after the newest tool result, and durable sidecar attachment. The adversarial identifier/output-bound test remains enabled.
+
+Exact commands and results for this review round:
+
+- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `5 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 10.04s`.
+- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py` — **passed**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+No downstream task improvement is claimed.
+
+## Sixth independent review round
+
+The sixth review found that status sidecars were added after normal row persistence and were therefore only in-memory: `_db_persisted` rows were skipped by the append-only flush, so a restart could lose the sidecar. The correction adds the smallest string-only row-identity backfill path. `hermes_state.py` now exposes `update_message_api_content(session_id, message_row_id, api_content)`, the flush records the returned durable row id, and persisted rows with a later status backfill are updated by that id. The sidecar remains a string; clean transcript content, role/tool ordering, and unsupported-value rejection are unchanged.
+
+The production contract test now persists user → assistant tool-call (`content=None`) → string tool-result rows through `SessionDB`, attaches status to the newest tool row, performs the row-identity update, closes and reopens the database, and asserts the same sidecar and replayed wire bytes. It would fail if only the in-memory dictionary changed.
+
+Exact commands and results for this review round:
+
+- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `6 passed in 0.50s`.
+- `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 9.43s`.
+- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py hermes_state.py` — **passed**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+No downstream task improvement is claimed.
+
+## Seventh independent review round
+
+The seventh review found that rebuilding a request for the same newest message appended another status block each time. The projection is now idempotent at the production persistence boundary: the first non-empty string `api_content` sidecar is treated as the feature-owned projection and reused verbatim on retries, including after reload. A later volatile status is deliberately ignored for that same message, so previously sent bytes remain fixed. User-authored status-looking text in clean content is never parsed or removed; only the sidecar is recognized. Stable row-identity backfill remains in place through `update_message_api_content()`.
+
+The regression test repeats the same-message build 20 times, then repeats it after a real `SessionDB` close/reopen, asserting identical wire bytes and exactly one owned status block. Realistic tool-call placement, persistence reload, adversarial output bounds, and unsupported-type rejection remain covered.
+
+Exact commands and results for this review round:
+
+- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `7 passed in 0.84s`.
+- `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 9.42s`.
+- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py hermes_state.py` — **passed**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+No downstream task improvement is claimed.
+
+## Eighth independent review round
+
+The eighth review found a collision with Hermes’ existing `api_content` uses for memory/plugin prefetch and sanitization-divergence replay. The status helper now preserves any pre-existing string sidecar byte-for-byte as the base and adds an exact terminal ownership envelope: `<hermes_status_projection>` containing the status block and `</hermes_status_projection>`. Only that exact terminal form, with the expected `<agent_status>` structure, is recognized as feature-owned on retries; lookalike or malformed content remains ordinary base text and is never deleted. The projection is therefore idempotent across persistence/reload while ordinary API-only sidecars still receive one status projection. Unsupported values remain fail-closed and stable row-identity backfill remains unchanged.
+
+Added coverage uses a realistic pre-existing memory/plugin sidecar, repeats same-message builds, checks exact base-byte preservation and one status block, and includes a malformed/lookalike marker.
+
+Exact commands and results for this review round:
+
+- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `8 passed in 0.84s`.
+- `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 9.41s`.
+- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py hermes_state.py` — **passed**, exit code 0.
+- `git diff --check` — **passed**, exit code 0.
+
+No downstream task improvement is claimed.
+
+## Terminal acceptance loop
+
+After the eight correction rounds, the experiment ran a fresh Hermes reviewer
+with an isolated home and no proposer-session context. Each attempt inspected the
+current diff and production persistence paths, reran the focused checks, and was
+required to end in `VERDICT: ACCEPT` or `VERDICT: REJECT`. Five terminal attempts
+rejected the candidate and their findings were returned to the original Hermes
+session: tool-result placement and unbounded identifiers, realistic
+`content=None` tool-call placement, post-flush database persistence, retry
+idempotence, and composition with pre-existing memory/plugin sidecars. The sixth
+fresh attempt accepted the resulting candidate.
+
+The accepted version passed **8 new behavior-contract tests and 36 existing
+sidecar/cache/turn-context regression tests**. The new coverage includes a real
+`SessionDB` close/reopen, unchanged-message retries, realistic assistant tool calls,
+tool-result placement closest to generation, bounded adversarial TODO data, and
+byte-preserving composition with existing API-only sidecars. This closes the
+proposer-reviewer correction loop for the scoped candidate: a rejection caused the
+running Hermes proposer to update its own checkout, and independent review repeated
+until acceptance. It still does not establish downstream task-quality uplift.
+
+## Limitations
+
+This is an implementation and audit run, not evidence that the status bar improves task success. The repository wrapper was initially blocked because its environment lacked pytest, but the final focused suite did execute through `uv run --with pytest` and passed 44 tests. That scoped suite is not the repository's entire test matrix. The status block is deliberately small and currently reports only budget and todo state; it does not summarize arbitrary tool-call counts, wall-clock time, constraints, or provider-specific state. The terminal reviewer is an independent, fresh model session rather than a separately trained evaluator. The general memory and universal artifact-reviewer gaps remain partly addressed rather than fully solved.
+
+## Proposed ablation campaign
+
+Use a fixed Hermes commit, fixed model/provider, fixed config, fixed tool permissions, fixed temperature/reasoning settings, and a versioned task suite with hermetic workspaces. Record raw trajectories and outcome evidence, not only final text. Run a baseline with all selected features enabled, then one feature disabled per arm:
+
+1. baseline;
+2. `display.model_status_bar: false` (versus true);
+3. memory retrieval/writes disabled while session search remains separately measured;
+4. background memory/Skill review disabled;
+5. verify-on-stop and `pre_verify` continuation disabled only in a safe test fixture;
+6. context compression disabled or replaced by a fixed no-op at a safe context size;
+7. delegation disabled for tasks that can run either single-agent or delegated.
+
+For each arm, keep task order randomized and repeat enough times for confidence intervals. Report task success, independent verifier pass rate, safety/approval violations, regression/retention on prior tasks, artifact activation/adherence, token and wall-clock cost, tool-call count, failure class, and user-visible latency. Include transfer tasks and negative controls. Compare paired runs where possible and distinguish mechanism operation from end-to-end benefit. A run should not be promoted because it improves only a noisy judge or only the current task set; preserve trajectories and failed/negative results, as required by Chapter 6’s evaluation sections and Chapter 8 lines 245–270, 297–320.

++## Run identity
++
++- Starting commit: `85c8956ec7f2b4607509980794995e1c5e21e292` (the pinned HEAD before edits).
++- Model/provider: `openai/gpt-5.6-luna` / `openrouter`.
++- Book audited: English edition under `/home/ubuntu/ai-agent-book/book-en/`; all ten `chapter1.md`–`chapter10.md` files were inspected with section-heading and targeted-term searches, followed by section-level reads. The book repository was not modified.
++
++## Four-claim audit
++
++| Reader claim | Book evidence | Hermes evidence | Disposition |
++|---|---|---|---|
++| Product-level ablation infrastructure | Chapter 1, “Harness Engineering” (lines 149–157), defines remove-one-component experiments; Chapter 6, “Ablation Infrastructure” (lines 662–706), calls for feature flags, fixed baselines, A/B methodology, and privacy-aware analytics. | Hermes has many config gates and operational telemetry, e.g. `hermes_cli/config_defaults.py` (`display.verify_on_stop`, `display.file_mutation_verifier`, `memory.write_approval`, `curator.*`), trajectory saving in `run_agent.py:2274–2292`, and evaluation/observability hooks, but no product-level campaign runner that holds a task set/model fixed and compares one disabled feature at a time. | **Absent** as a cohesive product capability; deferred. A campaign runner would be a larger evaluation product, not a safe incidental core feature. |
++| Model-visible Agent Status Bar | Chapter 2, “Agent Status Bar” (lines 787–817) distinguishes model-visible state from the human terminal bar and requires placement at context end; lines 819–835 give the structured `<agent_status>` example. Chapter 9, lines 233–239, also uses it as an inter-agent text channel. | Human-facing lifecycle/status plumbing exists in `run_agent.py:937–975`, `agent/display.py`, `hermes_cli/status.py`, and tests such as `tests/cli/test_cli_status_bar.py`; the model prompt is cached in `agent/turn_context.py:613–617`, while request-local API messages are built in `agent/conversation_loop.py:1488–1614`. Before this change there was no model-visible aggregate status block. | **Partly present**. Implemented the smallest compatible slice: opt-in request-local `<agent_status>` with API-call budget and active todo state. |
++| Forgetting/consolidation for persistent memory | Chapter 3, “Memory Compression and Organization Mechanisms” (lines 236–260), requires organization and privacy; Chapter 8, “Sleep Learning: Consolidation, Forgetting, and Capability Maintenance” (lines 297–320), requires offline batch consolidation, conflict handling, expiry/archive/delete with provenance and rollback. | Bounded memory is configured in `hermes_cli/config_defaults.py:1578–1602`; provider orchestration is in `agent/memory_manager.py`; background memory/skill review is in `agent/background_review.py`; Skill usage/staleness/archival is handled by `agent/curator.py`. These are real controls, but Curator is for agent-created Skills and bounded `MEMORY.md` is not a general evidence-backed memory consolidator with conflict resolution/retention evaluation. | **Partly present**, with the missing general mechanism intentionally deferred. Extending it safely needs provider-specific semantics, provenance, retention/transfer sets, and approval/rollback design; blindly deleting memory would violate safety and user expectations. |
++| General proposer-reviewer with independent execution-grounded verification | Chapter 1, lines 247–281, defines Verify/Correct; Chapter 5’s coding-harness material and Chapter 10, “Peer Collaboration Pattern” (lines 290–318), require a reviewer to obtain new execution/render/tool evidence, not merely reread text. | Hermes already has execution-grounded file mutation verification (`run_agent.py:3342–3465`), verify-on-stop and bounded `pre_verify` continuation (`agent/conversation_loop.py:6840–6959`), plugin `pre_verify` hooks, approval gates, background review (`agent/background_review.py`), and delegation (`tools/delegate_tool.py`). There is no universal artifact contract and no always-on independent proposer/reviewer workflow. | **Partly present**, and the proposed generic always-on mechanism is **intentionally deferred/incompatible as a default**: it would add cost/core surface and could duplicate existing verification. Use artifact-specific plugins/workflows when a concrete verifier exists. |
++
++## Change made
++
++Added an opt-in model-visible status bar:
++
++- `agent/model_status_context.py` renders a bounded, deterministic `<agent_status>` block containing API-call budget and active todo information. It ignores completed tasks and arbitrary extra fields. Its persistent sidecar helper appends only to the newest request message and stores the resulting wire content in `api_content`.
++- `agent/agent_init.py` reads `display.model_status_bar` (default false).
++- `hermes_cli/config_defaults.py` documents `display.model_status_bar: false`.
++- `agent/conversation_loop.py` appends status only to the newest API request copy and persists that exact wire content in the existing `api_content` sidecar. On later requests, historical sidecars are replayed unchanged, while the newest status is appended only to the newest message. Clean transcript content, roles, and the cached system prompt remain unchanged.
++- `tests/agent/test_model_status_context.py` adds behavior-contract tests for formatting, active-task selection, field isolation, and three successive request builds with byte-identical replay of all earlier wire messages.
++
++Deliberately rejected/deferred:
++
++- No always-on status bar: it costs tokens and is therefore opt-in.
++- No mutation of `MEMORY.md`/external providers: the evidence supports a larger consolidation lifecycle, not an unsafe delete/merge heuristic.
++- No generic proposer-reviewer core tool or mandatory second model: existing execution-grounded gates cover concrete paths; a universal reviewer needs a typed artifact/verifier contract and a campaign showing benefit.
++- No ablation runner in this change: it needs fixed datasets, outcome metrics, isolation, privacy/telemetry policy, and feature-flag control across surfaces.
++
++## Verification
++
++Exact commands run:
++
++1. `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py`
++   Result: exit code 0; compilation succeeded.
++2. `python3 - <<'PY' ... from agent.model_status_context import build_model_status_context ... PY`
++   Result: exit code 0; printed the expected block:
++   `<agent_status>`, `API calls: 3/10`, `Active tasks: 1 (in progress: 1)`, `Next active task: b — run tests`, `</agent_status>`.
++3. `scripts/run_tests.sh tests/agent/test_model_status_context.py -q`
++   Result: **blocked**, exit code 1. The repository runner reported no virtualenv containing pytest (`.venv` exists but has no pytest; no `venv`/`HERMES_PYTHON` fallback). No test result was fabricated.
++4. `uv run --with pytest pytest tests/agent/test_model_status_context.py -q`
++   Result: **passed**, `2 passed in 0.07s` (the isolated behavior-contract tests ran successfully through uv).
++5. `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py && git diff --check`
++   Result: **passed**, exit code 0; no whitespace errors.
++
++The repository wrapper was blocked by its environment lacking pytest, but the focused tests did execute and pass through `uv run --with pytest`. Existing tests were not weakened, and no approval, validator, or safety threshold was changed.
++
++## Independent review round
++
++The first candidate was rejected because it rewrote previously sent request bytes when adding each new status. This round corrected that defect by using persistent `api_content` sidecars and added three-request replay coverage. The reviewer’s scope was not expanded: no ablation campaign, memory consolidator, or generic reviewer loop was added.
++
++## Review-round verification
++
++Exact commands and results for the correction:
++
++- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `3 passed in 0.07s`.
++- `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 9.51s`.
++- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py` — **passed**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++The focused replay test proves that each earlier request message remains byte-identical in later request constructions and that the newest status is attached to the newest message. These are wire-construction tests, not an end-to-end provider run.
++
++## Second independent review round
++
++The second review found that the replay test helper accepted list-valued sidecars more broadly than the production request builder, which only replayed non-empty strings. The correction now centralizes the production type contract in `replay_api_content_sidecar()` (`agent/model_status_context.py`) and uses it in `agent/conversation_loop.py` for both current-turn and historical replay. Only non-empty strings are supported; lists/multimodal content, empty strings, mappings, numbers, and other unsupported values fail closed because Hermes persists `api_content` as an optional string. The tests call this same helper and cover string, list, empty, and unsupported values.
++
++Exact commands and results for this review round:
++
++- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `5 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**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++The review correction validates the production replay type check rather than using a more permissive test-only reconstruction. No book files were changed, and no downstream task improvement is claimed.
++
++## Third independent review round
++
++The third review found that list-valued sidecars were only safe in the in-memory request builder, not across Hermes’ persistence boundary: `hermes_state.py` and the flush path in `run_agent.py` persist `api_content` as an optional string, and `agent/turn_context.py` exposes string-only sidecar helpers. The correction therefore fails closed for every non-string content value and does not attach model status to unsupported multimodal/list messages. No database schema or persistence contract was widened.
++
++Exact commands and results for this review round:
++
++- `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**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++No multimodal support is claimed, and no downstream task improvement is claimed.
++
++## Fourth independent review round
++
++The fourth review found two production-path defects. First, status was being attached to the newest tool result even though Hermes persists and replays `api_content` only for user/assistant messages. The attachment helper now searches backward for the newest durable user/assistant message, leaving tool results unchanged; the production replay path remains restricted to those roles. This preserves role ordering, clean transcript content, and durable sidecar replay. Second, TODO identifiers were not bounded. `build_model_status_context()` now caps identifiers at 96 characters, descriptions at 200 characters, and the complete rendered block at 1200 characters while retaining the closing tag.
++
++New behavior-contract tests cover a successive request whose newest message is a tool result, confirm the sidecar is attached to the latest durable message and replays unchanged, and verify a 100,000-character TODO identifier cannot exceed the output bound. They call the same production replay helper used by `conversation_loop.py`.
++
++Exact commands and results for this review round:
++
++- `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**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++No downstream task improvement is claimed.
++
++## Fifth independent review round
++
++The fifth review identified a realistic tool-loop placement failure: assistant tool-call messages commonly have `content=None`, followed by a string tool result. Searching backward for a durable assistant then failed closed, and text-bearing assistant messages would place status before the newest tool evidence. The durable correction now targets the newest message directly. String `api_content` sidecars are persisted and replayed for `user`, `assistant`, and `tool` roles; unsupported values still fail closed, and clean transcript content and role/tool-call ordering are unchanged. When the newest message is a tool result, status is appended after that evidence, closest to generation.
++
++The focused successive-request test now uses assistant tool-call messages with `content=None` followed by string tool results across three requests. It asserts historical wire equality, status placement after the newest tool result, and durable sidecar attachment. The adversarial identifier/output-bound test remains enabled.
++
++Exact commands and results for this review round:
++
++- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `5 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 10.04s`.
++- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py` — **passed**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++No downstream task improvement is claimed.
++
++## Sixth independent review round
++
++The sixth review found that status sidecars were added after normal row persistence and were therefore only in-memory: `_db_persisted` rows were skipped by the append-only flush, so a restart could lose the sidecar. The correction adds the smallest string-only row-identity backfill path. `hermes_state.py` now exposes `update_message_api_content(session_id, message_row_id, api_content)`, the flush records the returned durable row id, and persisted rows with a later status backfill are updated by that id. The sidecar remains a string; clean transcript content, role/tool ordering, and unsupported-value rejection are unchanged.
++
++The production contract test now persists user → assistant tool-call (`content=None`) → string tool-result rows through `SessionDB`, attaches status to the newest tool row, performs the row-identity update, closes and reopens the database, and asserts the same sidecar and replayed wire bytes. It would fail if only the in-memory dictionary changed.
++
++Exact commands and results for this review round:
++
++- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `6 passed in 0.50s`.
++- `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 9.43s`.
++- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py hermes_state.py` — **passed**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++No downstream task improvement is claimed.
++
++## Seventh independent review round
++
++The seventh review found that rebuilding a request for the same newest message appended another status block each time. The projection is now idempotent at the production persistence boundary: the first non-empty string `api_content` sidecar is treated as the feature-owned projection and reused verbatim on retries, including after reload. A later volatile status is deliberately ignored for that same message, so previously sent bytes remain fixed. User-authored status-looking text in clean content is never parsed or removed; only the sidecar is recognized. Stable row-identity backfill remains in place through `update_message_api_content()`.
++
++The regression test repeats the same-message build 20 times, then repeats it after a real `SessionDB` close/reopen, asserting identical wire bytes and exactly one owned status block. Realistic tool-call placement, persistence reload, adversarial output bounds, and unsupported-type rejection remain covered.
++
++Exact commands and results for this review round:
++

++
++## Eighth independent review round
++
++The eighth review found a collision with Hermes’ existing `api_content` uses for memory/plugin prefetch and sanitization-divergence replay. The status helper now preserves any pre-existing string sidecar byte-for-byte as the base and adds an exact terminal ownership envelope: `<hermes_status_projection>` containing the status block and `</hermes_status_projection>`. Only that exact terminal form, with the expected `<agent_status>` structure, is recognized as feature-owned on retries; lookalike or malformed content remains ordinary base text and is never deleted. The projection is therefore idempotent across persistence/reload while ordinary API-only sidecars still receive one status projection. Unsupported values remain fail-closed and stable row-identity backfill remains unchanged.
++
++Added coverage uses a realistic pre-existing memory/plugin sidecar, repeats same-message builds, checks exact base-byte preservation and one status block, and includes a malformed/lookalike marker.
++
++Exact commands and results for this review round:
++
++- `uv run --with pytest pytest tests/agent/test_model_status_context.py -q` — **passed**, `8 passed in 0.84s`.
++- `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 9.41s`.
++- `python3 -m py_compile agent/model_status_context.py agent/conversation_loop.py agent/agent_init.py run_agent.py hermes_state.py` — **passed**, exit code 0.
++- `git diff --check` — **passed**, exit code 0.
++
++No downstream task improvement is claimed.
++
++## Terminal acceptance loop
++
++After the eight correction rounds, the experiment ran a fresh Hermes reviewer
++with an isolated home and no proposer-session context. Each attempt inspected the
++current diff and production persistence paths, reran the focused checks, and was
++required to end in `VERDICT: ACCEPT` or `VERDICT: REJECT`. Five terminal attempts
++rejected the candidate and their findings were returned to the original Hermes
++session: tool-result placement and unbounded identifiers, realistic
++`content=None` tool-call placement, post-flush database persistence, retry
++idempotence, and composition with pre-existing memory/plugin sidecars. The sixth
++fresh attempt accepted the resulting candidate.
++
++The accepted version passed **8 new behavior-contract tests and 36 existing
++sidecar/cache/turn-context regression tests**. The new coverage includes a real
++`SessionDB` close/reopen, unchanged-message retries, realistic assistant tool calls,
++tool-result placement closest to generation, bounded adversarial TODO data, and
++byte-preserving composition with existing API-only sidecars. This closes the
++proposer-reviewer correction loop for the scoped candidate: a rejection caused the
++running Hermes proposer to update its own checkout, and independent review repeated
++until acceptance. It still does not establish downstream task-quality uplift.
++
++## Limitations
++
++This is an implementation and audit run, not evidence that the status bar improves task success. The repository wrapper was initially blocked because its environment lacked pytest, but the final focused suite did execute through `uv run --with pytest` and passed 44 tests. That scoped suite is not the repository's entire test matrix. The status block is deliberately small and currently reports only budget and todo state; it does not summarize arbitrary tool-call counts, wall-clock time, constraints, or provider-specific state. The terminal reviewer is an independent, fresh model session rather than a separately trained evaluator. The general memory and universal artifact-reviewer gaps remain partly addressed rather than fully solved.
++
++## Proposed ablation campaign
++
++Use a fixed Hermes commit, fixed model/provider, fixed config, fixed tool permissions, fixed temperature/reasoning settings, and a versioned task suite with hermetic workspaces. Record raw trajectories and outcome evidence, not only final text. Run a baseline with all selected features enabled, then one feature disabled per arm:
++
++1. baseline;
++2. `display.model_status_bar: false` (versus true);
++3. memory retrieval/writes disabled while session search remains separately measured;
++4. background memory/Skill review disabled;
++5. verify-on-stop and `pre_verify` continuation disabled only in a safe test fixture;
++6. context compression disabled or replaced by a fixed no-op at a safe context size;
++7. delegation disabled for tasks that can run either single-agent or delegated.
++
++For each arm, keep task order randomized and repeat enough times for confidence intervals. Report task success, independent verifier pass rate, safety/approval violations, regression/retention on prior tasks, artifact activation/adherence, token and wall-clock cost, tool-call count, failure class, and user-visible latency. Include transfer tasks and negative controls. Compare paired runs where possible and distinguish mechanism operation from end-to-end benefit. A run should not be promoted because it improves only a noisy judge or only the current task set; preserve trajectories and failed/negative results, as required by Chapter 6’s evaluation sections and Chapter 8 lines 245–270, 297–320.

+Query: # Independent acceptance review of the self-update

+- clean transcript content and role alternation;
+- Hermes' string-only persisted `api_content` contract;
+- fail-closed behavior for list/multimodal, empty, mapping, numeric, and other
+  unsupported content;
+- default-off behavior, bounded deterministic output, and existing safety
+  gates.

+Rejected.
+
+Evidence:
+- The status is appended to source_messages[-1] / api_messages[-1] without requiring a user message. After a tool call, the newest message is normally a tool result, so the status is attached to that tool message.
+- Production replay explicitly restores sidecars only for user and assistant messages (agent/conversation_loop.py:1541–1554). Thus a status sidecar attached to a tool message is not replayed on the next request. This breaks the claimed persistent byte-identical replay and causes status behavior to vary across successive API calls.
+- build_model_status_context() does not fully enforce bounded output: item_id is converted to a string without truncation (agent/model_status_context.py:17), so an arbitrarily large todo ID can make the supposedly bounded status block arbitrarily large.
+
+The requested focused tests, compilation, and git diff --check all passed, but they do not exercise status injection after a tool-result message or oversized todo IDs.

+- In the normal tool-call path, the newest durable message is commonly an assistant tool-call message with content=None or empty content, followed by a tool result. append_persistent_model_status() selects that assistant message, then returns without attaching status because replay_api_content_sidecar(wire.get("content", "")) fails closed for empty/non-string content.
+- The production test does not cover this realistic shape: its tool-call assistant messages use ordinary string content ("calling tool" and "final tool call"). Consequently, the claimed model-visible status projection is absent during common tool-loop requests.

+╭─ ⚕ Hermes ───────────────────────────────────────────────────────────────────╮
+The candidate is rejected.
+
+Actionable finding:
+
+- Persistence boundary defect: append_persistent_model_status() mutates the newest message’s in-memory api_content after the relevant message has normally already been persisted. The turn-start user row is flushed before API-message construction (agent/turn_context.py:1219–1235), and assistant/tool rows are incrementally flushed before tool execution (agent/conversation_loop.py:6178–6185). The status projection is appended later (agent/conversation_loop.py:1600–1612), but _flush_messages_to_session_db_unlocked() deliberately skips messages carrying _db_persisted markers and there is no update/backfill operation for status sidecars. Consequently, the status is replayable within the current process but is absent after restart/session reload. This violates the claimed durable byte-identical replay and can change the provider prompt-cache prefix across process boundaries. The existing set_latest_user_api_content() only updates the latest user row and is not called by the new status path; it also cannot cover tool-result targets.

+
+I’m thinking through the API call structure. It seems like there’s an issue with un

+The candidate is rejected.
+
+Evidence:
+- The required focused tests passed: 6 passed, 36 passed.
+- Compilation and git diff --check passed.
+- However, append_persistent_model_status() is not idempotent. If the same newest message is used to build another request—such as an API retry, transient provider failure, empty-response retry, or another request rebuild before a new transcript message is appended—it appends a second <agent_status> block to the existing sidecar:
+  - agent/model_status_context.py: updated = base + "\n\n" + status
+  - The helper reads the already status-augmented wire content and never replaces or recognizes its prior status.
+- A direct production-helper check demonstrated this: invoking the helper 20 times on the same message produced 20 status blocks and changed the previously sent message bytes. This violates the stated byte-identical replay/prompt-cache requirement and the report’s claim that earlier wire messages remain stable.
+- The added successive-request test does not cover repeated request construction with the same newest message; it always appends new assistant/tool messages first.
+
+Actionable fix: make status projection idempotent for a message/request, or preserve an unmodified base sidecar and replace only the prior status projection rather than appending to the already projected wire content. Add a regression test that builds multiple requests with unchanged source_messages and asserts identical prior wire bytes and exactly one status block.

+Findings:

+- agent/model_status_context.py:84-91 treats any existing non-empty api_content sidecar as an already-installed model-status projection and returns without appending status. This is incorrect because Hermes already uses api_content for ordinary API-only composition, including memory/plugin prefetch context and sanitization-divergence replay. build_turn_context() can stamp the current user message with such a sidecar before append_persistent_model_status() runs. On a normal user turn with no tool result, the status helper therefore replays the pre-existing sidecar unchanged and injects no <agent_status> block. The claimed opt-in status projection is silently absent on that production path. The tests only cover a clean sidecar-free message and do not exercise an existing non-status sidecar.

+Query: # Second independent review: production-path mismatch
+
+The cache correction is sound for string content, but independent inspection
+found one remaining mismatch. Correct it without expanding scope:
+
+1. `append_persistent_model_status` writes a list-valued `api_content` for
+   multimodal content, but the real replay branch in
+   `agent/conversation_loop.py` only honors non-empty string sidecars. The
+   next request therefore drops the earlier multimodal status, while the test
+   helper `_wire_copy` incorrectly replays any type. Either support typed
+   sidecars safely throughout the real persistence/replay path or fail closed
+   by not enabling this feature on unsupported content. Do not leave a test
+   model that is more permissive than production.
+2. Refactor the sidecar replay decision into production code that the test can
+   call, or add coverage through the actual production request-building path.
+   The contract must exercise the same type check used by
+   `conversation_loop.py`, including string, list/multimodal, empty, and
+   unsupported values.
+3. Update the report with this second review round and exact verification.
+
+Run the focused tests, the same replay/cache regression set, compilation, and
+`git diff --check`. Do not change the book, commit, push, or claim downstream
+task improvement.

+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

+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

+Query: # Fifth independent review: realistic tool-call placement
+
+The second terminal acceptance review rejected the corrected candidate after
+running all requested checks. Continue the same self-update and address these
+exact findings:
+
+1. In the normal tool loop, the newest durable message is commonly an assistant
+   tool-call message whose `content` is `None` or empty, followed by a tool
+   result. The current backward search selects that assistant message, then
+   fails closed because its content is unsupported. The model-visible status is
+   therefore absent during common tool-loop requests.
+2. The current test uses assistant tool-call messages with ordinary string
+   content, so it does not cover the production shape above.
+3. If the assistant tool-call message does have text, the current code appends
+   status before the following tool result instead of at the request context
+   end. This violates the book/report placement requirement that current
+   model-visible state be closest to generation.
+
+Implement a durable solution at the actual string-only persistence/replay
+boundary. It may extend string `api_content` sidecar replay to tool messages if
+that is supported by the state and flush contracts, but must not widen the
+database type, mutate clean transcript content, disturb role/tool-call ordering,
+or attach status to unsupported list/multimodal content. Inspect and test the
+real production contract rather than relying on a permissive test helper.
+
+Add coverage for an assistant tool call with `content=None` followed by a
+string tool result, across at least three successive requests. Assert both
+byte-identical historical replay and placement after the newest tool evidence.
+Retain the adversarial output-bound test.
+
+Run the focused tests, existing sidecar/cache/turn-context regressions,
+compilation, and `git diff --check`. Update `BOOK_SELF_EVOLUTION_REPORT.md` with
+this fifth review and exact results. Do not edit the book, commit, push, or
+claim downstream task improvement.

+Query: # Sixth independent review: persisted-row backfill
+
+The third terminal acceptance review rejected the current candidate despite all
+focused tests passing. Continue the same self-update and correct this exact
+persistence-boundary defect:
+
+- `append_persistent_model_status()` mutates the newest message's in-memory
+  `api_content` after that message has normally already been persisted. The
+  turn-start user row is flushed before API-message construction
+  (`agent/turn_context.py` around 1219–1235), and assistant/tool rows are
+  incrementally flushed before tool execution (`agent/conversation_loop.py`
+  around 6178–6185). The status is appended later around 1600–1612.
+- `_flush_messages_to_session_db_unlocked()` deliberately skips messages with
+  `_db_persisted`, and the new path has no update/backfill operation. The
+  sidecar therefore survives within the current process but disappears after
+  restart/session reload, changing the provider prefix across process
+  boundaries.
+- Existing `set_latest_user_api_content()` only updates the latest user row, is
+  not called by the status path, and cannot cover a tool-result target.
+
+Implement the smallest safe durable update at Hermes' existing string-only
+database boundary. Do not widen the sidecar type or mutate clean transcript
+content. Preserve role/tool ordering and fail closed for unsupported content.
+Use stable row identity or another production-supported mechanism; do not rely
+on list position if it could update the wrong persisted message.
+
+Add a behavior test that persists a realistic user → assistant tool-call
+(`content=None`) → string tool-result sequence, attaches status to the newest
+tool evidence, reloads it through the real state/session path, and asserts the
+same string sidecar and byte-identical replay after reload. The test must fail
+if only the in-memory dictionary was changed.

+Query: # Seventh independent review: idempotent request rebuilds
+
+The fourth terminal acceptance review rejected the candidate after all focused
+tests passed. Continue the same self-update and correct this retry-path defect:
+
+- `append_persistent_model_status()` is not idempotent when the same newest
+  message is used to build another request (for example, a transient provider
+  failure, empty-response retry, or request rebuild before a new transcript
+  message). It computes `updated = base + "\n\n" + status` from wire content
+  that already contains the previous projection, so every rebuild adds another
+  `<agent_status>` block.
+- A direct production-helper exercise repeated the call 20 times and produced
+  20 status blocks, changing previously sent bytes and violating both the
+  prompt-cache stability claim and the total output bound.
+- Current tests always append a new transcript message before the next build
+  and therefore miss same-message retries.
+
+Make projection idempotent at the production persistence boundary. Preserve an
+unmodified base sidecar or safely recognize/replace only a status projection
+owned by this feature; do not delete user-authored text that merely resembles
+status markup. Decide and document whether volatile status values remain fixed
+for a retry of the same message or can be replaced, but previously sent prefix
+bytes must not drift unexpectedly. Keep clean transcript content unchanged,
+retain string-only fail-closed behavior, and durably persist the selected
+sidecar by stable row identity.
+
+Add a regression test that repeatedly builds requests with unchanged source
+messages, including a persisted/reloaded case. Assert identical wire bytes and
+exactly one owned status block. Retain realistic tool-call placement,
+persistence-reload, adversarial-bound, and unsupported-type coverage.

+╭─ ⚕ Hermes ───────────────────────────────────────────────────────────────────╮
+Addressed the eighth-review pre-existing-sidecar collision.
+
+Changes:
+
+- Existing string api_content is now preserved byte-for-byte as the base.
+- Added an exact feature-owned projection envelope:

+  - the <agent_status> block
+  - </hermes_status_projection>
+- Retries recognize only the exact terminal owned projection and reuse it unchanged.
+- Malformed or lookalike markers remain ordinary base content and are never removed.
+- Pre-existing memory/plugin sidecars now receive exactly one status projection.
+- Unsupported values remain fail-closed.
+- Stable row-identity backfill remains unchanged.

+Query: # Independent review of the first candidate
+
+An independent reviewer rejected the first candidate pending correction. Read
+the current diff and `BOOK_SELF_EVOLUTION_REPORT.md`, then address these exact
+findings without expanding scope:
+
+1. The request-local status is not prefix-stable across the tool loop. On call
+   1 it is appended to the user API copy; on call 2 that historical user copy
+   loses the status. On later calls, the previous tool result loses its old
+   status before the newest tool result gains a new one. This changes prior
+   wire bytes and invalidates the cached suffix, conflicting with Hermes'
+   byte-stability rule. Use a persistent-append design (for example, stable
+   `api_content` sidecars) or another design that proves previously sent wire
+   messages remain byte-identical. Keep clean transcript content unchanged.
+2. The tests exercise only the formatter. Add behavior-contract coverage for
+   the actual attachment/replay mechanism over at least three successive API
+   requests. Assert that each earlier wire message is byte-identical in every
+   later request and that the newest status is closest to generation.
+3. Correct the report's contradictory verification wording: the repository
+   wrapper was blocked because its environment lacked pytest, but the focused
+   tests did execute and pass through `uv run --with pytest`.
+
+Run the focused tests, relevant existing replay/cache tests, compilation, and
+`git diff --check`. Update the report with the review round and exact results.
+Do not claim end-to-end benefit without an ablation campaign, do not push or
+commit, and do not edit the book repository.

+**Inspecting skills for relevance**
+
+I need to take action and inspect the differences or reports related to the task.
+ It seems essential to ensure that my skills align with what's mandatory, particularly
+ focusing on Hermes and Test-Driven Development (TDD). I'm pondering how to best approach
+ this and make sure everything is relevant. It's a bit of a jumble in my mind, but
+ hopefully, I can clarify what exactly needs to be done!

+**Evaluating test edits**
+
+I need to focus on relevant existing replay and cache tests, specifically looking
+ at names like test_api_content_sidecar and background_review_cache_parity. I’m considering
+ editing them through Python—maybe using write instructions to apply the edits. However

+ available in the namespace. So, I’ll see if Python editing is an option, as that

+# Book-Driven Self-Evolution Report
+
+## Run identity
+
+- Starting commit: `85c8956ec7f2b4607509980794995e1c5e21e292` (the pinned HEAD at inspection time).
+- Model/provider: `openai/gpt-5.6-luna` via `openrouter`.
+- Book source read: `/home/ubuntu/ai-agent-book/book-en/`, all ten chapter files inspected by heading scans, targeted searches, and section reads. The book repository was not modified.
+
+## Opportunities identified and disposition
+
+1. **Evidence-backed trajectory signals (implemented).** Chapter 8, “Deriving Learning Signals from Operational Trajectories” (§8, lines 19–61), says evolution must start from evaluation, preserve immutable raw trajectories, and distinguish outcome/process evidence rather than trusting a scalar or self-summary. Hermes already persisted trajectories through `run_agent.py:2279-2292`, `agent/agent_runtime_helpers.py:76-243`, and `agent/trajectory.py:30-61`, but the JSONL record had no structured, deterministic evaluation signal. I added `agent.trajectory.derive_trajectory_signals()` and persisted its result under `evaluation`. It only inspects observable tool results (`success: false`), records completion status, and leaves the original messages unchanged.
+
+2. **Offline evolution with validation and rollback (already substantially present; no duplicate implementation).** Chapter 8, “Building a Continual-Evolution Closed Loop” (§8, lines 239–369), requires candidate changes, validation, release, and rollback. Hermes has the curator lifecycle in `agent/curator.py:1496-1760`, skill validation in `tools/skill_manager_tool.py:566-623`, and recoverable snapshots/rollback in `agent/curator_backup.py:216-638`, with behavior tests in `tests/agent/test_curator.py` and `tests/agent/test_curator_backup.py`. Adding another update system would duplicate existing infrastructure and increase mutation risk, so this was rejected.
+
+3. **Ablation and observability campaign (deferred as a campaign, not silently claimed).** Chapter 6, “Ablation Infrastructure” (§6, lines 662–706), and Chapter 1, “Context ablation” (§1, lines 141–159), call for fixed baselines, one-feature-at-a-time removal, and operational evidence. Hermes has trajectory persistence, curator reports, usage accounting, and tests, but this run did not have a fixed task corpus, deterministic model fixture, or safe experiment runner. Building a broad benchmark harness here would be speculative and larger than the smallest cohesive improvement. The report defines the campaign below.
+
+4. **Multi-agent independent cross-validation (deferred).** Chapter 10, “When Is Multi-Agent Truly Better Than a Single Agent?” (§10, lines 69–96) and “Cascading Amplification of Errors” (§10, lines 577–598), require independent information or evidence, not merely more agents. Hermes already has delegation and kanban infrastructure (`tools/delegate_tool.py`, `plugins/kanban/`, and the delegation configuration), so a generic reviewer would add cost and coordination surface without a concrete task contract. No change made.
+
+5. **Context-cache stability (preserved, not changed).** Chapter 2, “KV Cache-Friendly Context Design” (§2, lines 404–546), says stable system/tool prefixes are architectural constraints. The implementation adds metadata only to persisted JSONL trajectories and does not alter prompts, tools, or in-conversation messages.
+
+## Changes made
+
+- Added `derive_trajectory_signals()` to `agent/trajectory.py`.
+- Added an `evaluation` object to saved JSONL entries. It contains `outcome`, `tool_errors`, `tool_results`, and a conservative `process_warning`.
+- Added behavior-contract tests in `tests/agent/test_trajectory.py` covering tool-error detection and the invariant that persisted messages are unchanged.
+
+The implementation deliberately does not call an LLM judge, rewrite skills, alter prompts, infer success from prose, or change role ordering. This keeps the core tool surface and safety gates unchanged.
+
+## Deliberately rejected or deferred
+
+- No automatic skill/prompt/program/model mutation from one trajectory. Chapter 8 explicitly warns that unverified online updates amplify noise and prompt injection (§8, lines 3–11, 297–369).
+- No new core tool, environment variable, or dependency.
+- No broad evaluation dashboard or automatic ablation scheduler without a fixed corpus and acceptance criteria.
+- No claim that deterministic tool-error counts are a complete verifier; they are only low-level evidence.
+
+## Review round correction
+
+The independent review identified that the first implementation parsed only bare JSON, while the production conversion path emits bundled `<tool_response>` XML containing JSON envelopes with nested `content`. The implementation now recognizes multiple wrapped entries, parses nested object/string content conservatively, and ignores malformed or unsupported shapes. The new end-to-end test exercises `agent.agent_runtime_helpers.convert_to_trajectory_format()` before saving and verifies one failed result among two bundled responses. The original `conversations` list is asserted unchanged.
+
+## Second review round correction
+
+The fresh review found two real persistence paths that bypassed `save_trajectory()`: the JSONL entry assembled in `batch_runner.py` and the pretty-printed sample entry assembled in `run_agent.py` when `save_sample` is enabled. I inspected both paths and introduced `agent.trajectory.build_trajectory_entry()` as the shared entry builder. `agent/trajectory.py:91-128` now uses it for the existing append writer; `batch_runner.py:49-50,473-486` uses it while retaining its existing JSONL file I/O, flush/fsync behavior, filenames, and batch-specific fields; `run_agent.py:203-204,7530-7540` uses it while retaining the sample filename, pretty-printing, error handling, and query field. The builder preserves the supplied `conversations` object and adds the same backward-compatible `evaluation` field to all three persistence paths.
+
+The focused contract test verifies shared-field preservation. The existing conversion-and-save test continues to verify production-shaped XML tool results and unchanged conversation data.
+
+## Third review round correction
+
+The third review found two issues. First, a single recognized envelope could increment `tool_errors` once for top-level `success: false` and again for nested `content.success: false`. The signal derivation now computes one `failed` boolean per recognized payload, so each tool result contributes at most one error. A regression test covers both flags together.
+
+Second, a repository-wide search for direct ShareGPT/trajectory-shaped persistence found `mini_swe_runner.py` as the remaining production trajectory producer. Its `run_task()` result and `run_batch()` JSONL path now use `build_trajectory_entry()` while retaining the existing result fields, output filename handling, immediate flushes, and error record behavior. The empty error result also receives the metadata contract. The search also found unrelated records containing a `conversations` key (`mcp_serve.py`, session/audit exports, gateway state, plugins, and compression/transformation utilities); these are not ShareGPT trajectory producers and were deliberately left unchanged. The scope is therefore all identified Hermes ShareGPT trajectory producers: standard `save_trajectory()`, `run_agent.py` sample output, `batch_runner.py`, and `mini_swe_runner.py`.
+
+## Verification
+
+Exact commands and results:
+
+```text

+# Result: all ten chapter*.md files inspected; targeted section output was collected.
+
+.venv/bin/python -m pytest tests/agent/test_trajectory.py -q

+# Result (third review round): passed
+
+git diff --check
+# Result (third review round): passed
+```
+
+The repository's prescribed runner was attempted exactly and could not run because the checkout's `.venv` lacks pytest; the equivalent isolated `uv run` verification passed both new tests. No full suite was claimed.
+
+## Limitations
+
+- One implementation run and two unit tests show only that the metadata contract works. They are not evidence that trajectory signals improve task success, reduce cost, or improve safety.
+- `success: false` detection depends on tool handlers exposing that field in JSON; non-JSON output and domain-specific failures remain uncertain.
+- `completed=True` means the existing runtime completion path reported completion, not that the external task is correct. The field is intentionally named `outcome` and accompanied by process evidence rather than treated as ground truth.
+- No live model calls, benchmark tasks, or user data were used.
+
+## Proposed ablation campaign
+
+Use a fixed, versioned task corpus with isolated temporary Hermes homes, pinned model/provider/config, fixed tool availability, and deterministic seeds where supported. Record success, tool-error rate, policy/safety violations, latency, token usage, and cache-related request metadata. Run enough repetitions for confidence intervals and keep a held-out task split.
+
+Baseline: current Hermes with trajectory persistence and the new evaluation metadata enabled, but no automatic mutation. Compare one feature disabled at a time:
+
+1. Disable structured trajectory evaluation metadata; retain raw trajectory persistence.
+2. Disable raw trajectory persistence; retain ordinary task execution.
+3. Disable curator offline review while retaining metadata.
+4. Disable curator backup/rollback, only in a disposable sandbox, to measure operational risk—not production behavior.
+5. Disable context compression while retaining stable prefixes.
+6. Disable delegation for tasks that have a defined delegation path.
+7. Disable individual skill injection/progressive disclosure for matching task families.
+
+For every comparison, require that the fixed baseline and ablation use identical prompts, toolsets, model, credentials, task order, and safety/approval settings. Treat any regression in safety or policy compliance as a release blocker even if task success rises. The campaign should first validate that the new metadata predicts independently verified failures, then test whether using it in a separately reviewed offline evolution process improves held-out performance without negative transfer. A single run must never authorize self-modification.

++# Book-Driven Self-Evolution Report
++
++## Run identity
++
++- Starting commit: `85c8956ec7f2b4607509980794995e1c5e21e292` (the pinned HEAD at inspection time).
++- Model/provider: `openai/gpt-5.6-luna` via `openrouter`.
++- Book source read: `/home/ubuntu/ai-agent-book/book-en/`, all ten chapter files inspected by heading scans, targeted searches, and section reads. The book repository was not modified.
++
++## Opportunities identified and disposition
++
++1. **Evidence-backed trajectory signals (implemented).** Chapter 8, “Deriving Learning Signals from Operational Trajectories” (§8, lines 19–61), says evolution must start from evaluation, preserve immutable raw trajectories, and distinguish outcome/process evidence rather than trusting a scalar or self-summary. Hermes already persisted trajectories through `run_agent.py:2279-2292`, `agent/agent_runtime_helpers.py:76-243`, and `agent/trajectory.py:30-61`, but the JSONL record had no structured, deterministic evaluation signal. I added `agent.trajectory.derive_trajectory_signals()` and persisted its result under `evaluation`. It only inspects observable tool results (`success: false`), records completion status, and leaves the original messages unchanged.
++
++2. **Offline evolution with validation and rollback (already substantially present; no duplicate implementation).** Chapter 8, “Building a Continual-Evolution Closed Loop” (§8, lines 239–369), requires candidate changes, validation, release, and rollback. Hermes has the curator lifecycle in `agent/curator.py:1496-1760`, skill validation in `tools/skill_manager_tool.py:566-623`, and recoverable snapshots/rollback in `agent/curator_backup.py:216-638`, with behavior tests in `tests/agent/test_curator.py` and `tests/agent/test_curator_backup.py`. Adding another update system would duplicate existing infrastructure and increase mutation risk, so this was rejected.
++
++3. **Ablation and observability campaign (deferred as a campaign, not silently claimed).** Chapter 6, “Ablation Infrastructure” (§6, lines 662–706), and Chapter 1, “Context ablation” (§1, lines 141–159), call for fixed baselines, one-feature-at-a-time removal, and operational evidence. Hermes has trajectory persistence, curator reports, usage accounting, and tests, but this run did not have a fixed task corpus, deterministic model fixture, or safe experiment runner. Building a broad benchmark harness here would be speculative and larger than the smallest cohesive improvement. The report defines the campaign below.
++
++4. **Multi-agent independent cross-validation (deferred).** Chapter 10, “When Is Multi-Agent Truly Better Than a Single Agent?” (§10, lines 69–96) and “Cascading Amplification of Errors” (§10, lines 577–598), require independent information or evidence, not merely more agents. Hermes already has delegation and kanban infrastructure (`tools/delegate_tool.py`, `plugins/kanban/`, and the delegation configuration), so a generic reviewer would add cost and coordination surface without a concrete task contract. No change made.
++
++5. **Context-cache stability (preserved, not changed).** Chapter 2, “KV Cache-Friendly Context Design” (§2, lines 404–546), says stable system/tool prefixes are architectural constraints. The implementation adds metadata only to persisted JSONL trajectories and does not alter prompts, tools, or in-conversation messages.
++
++## Changes made
++
++- Added `derive_trajectory_signals()` to `agent/trajectory.py`.
++- Added an `evaluation` object to saved JSONL entries. It contains `outcome`, `tool_errors`, `tool_results`, and a conservative `process_warning`.
++- Added behavior-contract tests in `tests/agent/test_trajectory.py` covering tool-error detection and the invariant that persisted messages are unchanged.
++
++The implementation deliberately does not call an LLM judge, rewrite skills, alter prompts, infer success from prose, or change role ordering. This keeps the core tool surface and safety gates unchanged.
++
++## Deliberately rejected or deferred
++
++- No automatic skill/prompt/program/model mutation from one trajectory. Chapter 8 explicitly warns that unverified online updates amplify noise and prompt injection (§8, lines 3–11, 297–369).
++- No new core tool, environment variable, or dependency.
++- No broad evaluation dashboard or automatic ablation scheduler without a fixed corpus and acceptance criteria.
++- No claim that deterministic tool-error counts are a complete verifier; they are only low-level evidence.
++
++## Review round correction
++
++The independent review identified that the first implementation parsed only bare JSON, while the production conversion path emits bundled `<tool_response>` XML containing JSON envelopes with nested `content`. The implementation now recognizes multiple wrapped entries, parses nested object/string content conservatively, and ignores malformed or unsupported shapes. The new end-to-end test exercises `agent.agent_runtime_helpers.convert_to_trajectory_format()` before saving and verifies one failed result among two bundled responses. The original `conversations` list is asserted unchanged.
++
++## Second review round correction
++
++The fresh review found two real persistence paths that bypassed `save_trajectory()`: the JSONL entry assembled in `batch_runner.py` and the pretty-printed sample entry assembled in `run_agent.py` when `save_sample` is enabled. I inspected both paths and introduced `agent.trajectory.build_trajectory_entry()` as the shared entry builder. `agent/trajectory.py:91-128` now uses it for the existing append writer; `batch_runner.py:49-50,473-486` uses it while retaining its existing JSONL file I/O, flush/fsync behavior, filenames, and batch-specific fields; `run_agent.py:203-204,7530-7540` uses it while retaining the sample filename, pretty-printing, error handling, and query field. The builder preserves the supplied `conversations` object and adds the same backward-compatible `evaluation` field to all three persistence paths.
++
++The focused contract test verifies shared-field preservation. The existing conversion-and-save test continues to verify production-shaped XML tool results and unchanged conversation data.
++
++## Third review round correction
++
++The third review found two issues. First, a single recognized envelope could increment `tool_errors` once for top-level `success: false` and again for nested `content.success: false`. The signal derivation now computes one `failed` boolean per recognized payload, so each tool result contributes at most one error. A regression test covers both flags together.
++
++Second, a repository-wide search for direct ShareGPT/trajectory-shaped persistence found `mini_swe_runner.py` as the remaining production trajectory producer. Its `run_task()` result and `run_batch()` JSONL path now use `build_trajectory_entry()` while retaining the existing result fields, output filename handling, immediate flushes, and error record behavior. The empty error result also receives the metadata contract. The search also found unrelated records containing a `conversations` key (`mcp_serve.py`, session/audit exports, gateway state, plugins, and compression/transformation utilities); these are not ShareGPT trajectory producers and were deliberately left unchanged. The scope is therefore all identified Hermes ShareGPT trajectory producers: standard `save_trajectory()`, `run_agent.py` sample output, `batch_runner.py`, and `mini_swe_runner.py`.
++
++## Verification
++
++Exact commands and results:
++
++```text
++python3 - <<'PY' ...  # book file inventory and all-chapter heading/search inspection
++# Result: all ten chapter*.md files inspected; targeted section output was collected.
++
++.venv/bin/python -m pytest tests/agent/test_trajectory.py -q
++# Result: failed before test execution: No module named pytest
++
++scripts/run_tests.sh tests/agent/test_trajectory.py -q
++# Result: failed because no configured virtualenv with pytest exists.
++
++uv run --with pytest pytest tests/agent/test_trajectory.py -q
++# Result (third review round): 6 passed in 0.12s
++
++uv run --with pytest pytest tests/agent/test_trajectory.py tests/test_batch_runner_checkpoint.py tests/test_batch_runner_durability.py tests/integration/test_batch_runner.py tests/test_trajectory_compressor.py -q
++# Result (third review round): 44 passed in 0.62s
++
++python3 -m py_compile agent/trajectory.py agent/agent_runtime_helpers.py batch_runner.py run_agent.py mini_swe_runner.py tests/agent/test_trajectory.py
++# Result (third review round): passed
++
++git diff --check
++# Result (third review round): passed
++```
++
++The repository's prescribed runner was attempted exactly and could not run because the checkout's `.venv` lacks pytest; the equivalent isolated `uv run` verification passed both new tests. No full suite was claimed.
++
++## Limitations
++
++- One implementation run and two unit tests show only that the metadata contract works. They are not evidence that trajectory signals improve task success, reduce cost, or improve safety.
++- `success: false` detection depends on tool handlers exposing that field in JSON; non-JSON output and domain-specific failures remain uncertain.
++- `completed=True` means the existing runtime completion path reported completion, not that the external task is correct. The field is intentionally named `outcome` and accompanied by process evidence rather than treated as ground truth.
++- No live model calls, benchmark tasks, or user data were used.
++
++## Proposed ablation campaign
++
++Use a fixed, versioned task corpus with isolated temporary Hermes homes, pinned model/provider/config, fixed tool availability, and deterministic seeds where supported. Record success, tool-error rate, policy/safety violations, latency, token usage, and cache-related request metadata. Run enough repetitions for confidence intervals and keep a held-out task split.
++
++Baseline: current Hermes with trajectory persistence and the new evaluation metadata enabled, but no automatic mutation. Compare one feature disabled at a time:
++
++1. Disable structured trajectory evaluation metadata; retain raw trajectory persistence.
++2. Disable raw trajectory persistence; retain ordinary task execution.
++3. Disable curator offline review while retaining metadata.
++4. Disable curator backup/rollback, only in a disposable sandbox, to measure operational risk—not production behavior.
++5. Disable context compression while retaining stable prefixes.
++6. Disable delegation for tasks that have a defined delegation path.
++7. Disable individual skill injection/progressive disclosure for matching task families.
++
++For every comparison, require that the fixed baseline and ablation use identical prompts, toolsets, model, credentials, task order, and safety/approval settings. Treat any regression in safety or policy compliance as a release blocker even if task success rises. The campaign should first validate that the new metadata predicts independently verified failures, then test whether using it in a separately reviewed offline evolution process improves held-out performance without negative transfer. A single run must never authorize self-modification.

+candidate self-update produced by another Hermes session after reading all of
+*AI Agents in Depth*. The proposer was not given any candidate improvement or
+alleged capability gap; it selected this change itself.
+
+Review the current diff and `BOOK_SELF_EVOLUTION_REPORT.md`. Inspect the actual

+conservative signals from the real persisted ShareGPT-format trajectory,
+preserves existing trajectory content and compatibility, and accurately
+documents its evidence boundary.
+
+Run these checks yourself (and any additional focused read-only checks needed):

+  - tests/test_trajectory_compressor.py: 21 passed
+  - py_compile: passed
+  - git diff --check: passed
+- Concrete production-parity defect: agent.agent_runtime_helpers.convert_to_trajectory_format() persists tool results as XML-wrapped JSON, for example:
+  - <tool_response>\n{"tool_call_id": ..., "content": {"success": false, ...}}\n</tool_response>
+- derive_trajectory_signals() attempts json.loads() on the entire value, which therefore fails for real persisted tool-result messages. It does not inspect the nested content object or XML-wrapped responses.
+- Consequently, the advertised success: false detection produces tool_errors: 0 and no warning for actual production trajectories containing tool failures. A direct synthetic JSON test passes, but it does not exercise the real conversion/persistence path.
+- The report’s claim that the metadata “only inspects observable tool results (success: false)" is materially inaccurate for the persisted ShareGPT-format trajectory currently produced by Hermes.
+
+Actionable finding:
+- Derive signals from the actual converted format, including XML-wrapped and multiple bundled <tool_response> entries, and add an end-to-end test that converts a production-shaped internal assistant/tool exchange before saving and verifies the failure signal.

+- The metadata is not added to all production trajectory persistence paths. batch_runner.py writes ShareGPT-format entries directly at batch_runner.py:473-487, and the save_sample path in run_agent.py:7530-7541 also writes entries directly. Neither includes the new evaluation object. The report says evaluation metadata is persisted for saved JSONL entries and presents the change as covering trajectory persistence generally, but these documented/real persistence paths remain uncovered. This creates inconsistent metadata across trajectory datasets and means the candidate does not satisfy its stated persistence scope. Either route all persistence through a shared writer or add equivalent metadata to those paths, with focused tests.

+Query: # Independent acceptance review of the self-update
+
+Act as the terminal reviewer in a proposer-reviewer self-evolution loop. You
+are inspecting a Hermes checkout that started from commit
+`85c8956ec7f2b4607509980794995e1c5e21e292` and now contains an uncommitted
+candidate self-update produced by another Hermes session after reading all of
+*AI Agents in Depth*. The proposer was not given any candidate improvement or
+alleged capability gap; it selected this change itself.
+
+Review the current diff and `BOOK_SELF_EVOLUTION_REPORT.md`. Inspect the actual
+production trajectory conversion and persistence paths rather than trusting
+the report. Determine whether the new evaluation metadata correctly derives
+conservative signals from the real persisted ShareGPT-format trajectory,
+preserves existing trajectory content and compatibility, and accurately
+documents its evidence boundary.
+
+Run these checks yourself (and any additional focused read-only checks needed):
+
+```bash
+uv run --with pytest pytest tests/agent/test_trajectory.py -q
+uv run --with pytest pytest tests/test_trajectory_compressor.py -q
+python3 -m py_compile agent/trajectory.py agent/agent_runtime_helpers.py 
+run_agent.py
+git diff --check
+```
+
+Do not edit any file. Reject the candidate if you find a concrete correctness,
+production/test-parity, persistence, compatibility, safety, or material
+report-accuracy defect. Do not reject merely because this bounded candidate
+does not implement every opportunity found in the book or because no downstream
+ablation campaign has run; those are explicit evidence boundaries.
+
+Give concise evidence for the decision. End with exactly one machine-readable
+line:
+

+┌─ Reasoning ──────────────────────────────────────────────────────────────────┐
+**Evaluating persistence paths**
+
+I need to decide to reject claims about all persistence paths being false. The mini
+_swe_runner seems to represent a production trajectory that’s untouched. The user
+ is focused on the actual conversion and persistence paths. It looks like the candidate
+ alters three known paths, but mini_swe might be a separate runner. There's also a
+ bug where errors are double-counted if the envelope itself is false. I need to check
+ how the converter works and what the report says about the paths.**Reviewing persistence paths**
+
+It mentions “all three persistence paths,” but I think mini_swe might be a separate
+ tool. The save_trajectory is crucial here. Adding an evaluation field to the batch
+ output could change the schema, but it generally stays backward-compatible. I see
+ that while the report claims certain commands, the included files mention batch/test
+, rather than just the three requested. It states some batch changes are uncommitted
+, making me think we might need to run custom tests to check for double counts and
+ the mini path. Also, I should address the untracked tests included.**Clarifying task outcomes**
+
+Okay, the “conservative” outcome being marked as completed or failed, but possibly
+ incorrectly, isn't about the task's actual correctness; that’s documented. The main
+ issue lies in the nested success being marked false, which leads to double counting
+. I think it's important to demonstrate this clearly at the terminal level, so I can
+ track how it all adds up. This way, I can ensure that the outcomes accurately reflect
+ what’s happening in the process.
+└──────────────────────────────────────────────────────────────────────────────┘

+╭─ ⚕ Hermes ───────────────────────────────────────────────────────────────────╮
+Findings:
+
+- derive_trajectory_signals() can overcount errors. For one valid tool-result envelope containing both top-level "success": false and nested content.success: false, it increments tool_errors twice while incrementing tool_results once. The metadata therefore does not represent a per-tool-result error count and is not conservative in the stated sense.
+- The report claims all relevant persistence paths use the shared builder, but mini_swe_runner.py still directly persists converted ShareGPT trajectories at mini_swe_runner.py:559–604. That path receives the same production-style converted trajectory but never receives the new evaluation metadata. The report’s “all three persistence paths” claim is therefore inaccurate unless this runner is explicitly outside the evidence boundary, which the report does not state.
+
+Checks run:
+
+- uv run --with pytest pytest tests/agent/test_trajectory.py -q → 4 passed
+- uv run --with pytest pytest tests/test_trajectory_compressor.py -q → 21 passed
+- python3 -m py_compile agent/trajectory.py agent/agent_runtime_helpers.py run_agent.py → passed
+- git diff --check → passed
+
+Actionable fixes: make error detection count each recognized result at most once, and either update or explicitly exclude/document mini_swe_runner.py’s trajectory persistence path.

+Query: # Independent review of the autonomous candidate
+
+An independent reviewer rejected your candidate pending correction. Read the
+current diff and `BOOK_SELF_EVOLUTION_REPORT.md`, then address this exact 
+finding
+without expanding scope:
+
+The real production path in
+`agent.agent_runtime_helpers.convert_to_trajectory_format()` persists tool
+results as one or more XML-wrapped JSON objects, for example:
+
+```text
+<tool_response>
+{"tool_call_id": "...", "name": "...", "content": {"success": false}}
+</tool_response>
+```
+
+`derive_trajectory_signals()` currently attempts `json.loads()` on the entire
+wrapped value, so it reports zero tool errors for a real failed tool result.
+The existing synthetic test uses bare JSON and therefore misses this
+production/test-parity defect.
+
+Derive conservative signals from the actual converted ShareGPT trajectory,
+including multiple bundled `<tool_response>` entries and nested `content`.
+Fail closed on malformed or unsupported shapes. Add an end-to-end behavior test
+that passes a production-shaped internal assistant/tool exchange through the
+real conversion path before saving and verifies the resulting failure signal.
+Preserve the original trajectory messages byte-for-byte and keep the metadata
+backward-compatible.
+
+Run the focused tests, the existing trajectory-compressor tests, compilation,
+and `git diff --check`. Update the report with this review round and exact
+results. Do not claim downstream benefit without the separate ablation campaign,
+do not push or commit, and do not edit the book repository.

+Query: # Second independent review of the autonomous candidate
+
+A fresh independent reviewer rejected the revised candidate. The XML parsing
+and focused tests now pass, but the claimed persistence scope is inconsistent:
+
+- `batch_runner.py` writes ShareGPT-format trajectory entries directly around
+  its JSONL persistence path instead of using 
+`agent.trajectory.save_trajectory()`;
+- the `save_sample` path in `run_agent.py` also writes trajectory entries
+  directly;
+- neither path currently includes the new `evaluation` object.
+
+Inspect the actual code rather than relying on these line references. Make the
+metadata contract consistent across real trajectory persistence paths, ideally
+through one shared entry builder/writer when that can be done without changing
+existing filenames, schemas, return behavior, or error handling. Add focused
+tests for the batch and sample paths or their shared production helper. Preserve
+all existing fields and conversation bytes.
+
+Run the new tests, relevant existing batch/trajectory tests, compilation, and
+`git diff --check`. Update `BOOK_SELF_EVOLUTION_REPORT.md` with this review 
+round
+and exact results. Keep the same claim boundary, do not commit or push, and do
+not edit the book repository.

+Query: # Third independent review of the autonomous candidate
+
+A third fresh reviewer rejected the candidate on two concrete findings:
+
+1. `derive_trajectory_signals()` can count one tool result as two errors when a
+   valid envelope contains both top-level `"success": false` and nested
+   `content.success: false`. Each recognized tool result must contribute at
+   most one to `tool_errors`.
+2. `mini_swe_runner.py` directly persists converted ShareGPT trajectories and
+   still omits the new evaluation metadata. Inspect this path and either bring
+   it under the shared entry contract without changing its existing output
+   behavior, or explicitly narrow and justify the feature boundary if it is a
+   genuinely different artifact. The current report must not claim consistent
+   coverage while silently excluding it.
+
+Add regression coverage for the per-result count invariant and the selected
+handling of the mini-SWE path. Search once more for equivalent direct
+ShareGPT/trajectory persistence sites so the report can state its scope
+accurately. Run the focused and relevant existing tests, compilation, and
+`git diff --check`; update the report with exact results. Do not commit, push,
+or edit the book repository.

First, a single recognized envelope could increment `tool_errors` once for top-level `success: false` and again for nested `content.success: false`. The signal derivation now computes one `failed` boolean per recognized payload, so each tool result contributes at most one error. A regression test covers both flags together.\n\nSecond, a repository-wide search for direct ShareGPT/trajectory-shaped persistence found `mini_swe_runner.py` as the remaining production trajectory producer. Its `run_task()` result and `run_batch()` JSONL path now use `build_trajectory_entry()` while retaining the existing result fields, output filename handling, immediate flushes, and error record behavior. The empty error result also receives the metadata contract. The search also found unrelated records containing a `conversations` key (`mcp_serve.py`, session/audit exports, gateway state, plugins, and compression/transformation utilities); these are not ShareGPT trajectory producers and were deliberately left unchanged. The scope is therefore all identified Hermes ShareGPT trajectory producers: standard `save_trajectory()`, `run_agent.py` sample output, `batch_runner.py`, and `mini_swe_runner.py`.\n\n''' s=s.replace('## Verification\n',addition+'## Verification\n',1) s=s.replace('''uv run --with pytest pytest tests/agent/test_trajectory.py -q # Result (second review round): 4 passed in 0.11s uv run --with pytest pytest tests/agent/test_trajectory.py tests/test_batch_runner_checkpoint.py tests/test_batch_runner_durability.py tests/integration/test_batch_runner.py tests/test_trajectory_compressor.py -q # Result (second review round): 42 passed in 0.60s python3 -m py_compile agent/trajectory.py agent/agent_runtime_helpers.py batch_runner.py run_agent.py tests/agent/test_trajectory.py # Result (second review round): passed git diff --check # Result (second review round): passed''','''uv run --with pytest pytest tests/agent/test_trajectory.py -q # Result (third review round): 6 passed in 0.12s uv run --with pytest pytest tests/agent/test_trajectory.py tests/test_batch_runner_checkpoint.py tests/test_batch_runner_durability.py tests/integration/test_batch_runner.py tests/test_trajectory_compressor.py -q # Result (third review round): 44 passed in 0.62s python3 -m py_compile agent/trajectory.py agent/agent_runtime_helpers.py batch_runner.py run_agent.py mini_swe_runner.py tests/agent/test_trajectory.py # Result (third review round): passed git diff --check # Result (third review round): passed''') p.write_text(s) PY uv run --with pytest pytest tests/agent/test_trajectory.py tests/test_batch_runner_checkpoint.py tests/test_batch_runner_durability.py tests/integration/test_batch_runner.py tests/test_trajectory_compressor.py -q python3 -m py_compile agent/trajectory.py agent/agent_runtime_helpers.py batch_runner.py run_agent.py mini_swe_runner.py tests/agent/test_trajectory.py git diff --check git status --short  1.0s

+╭─ ⚕ Hermes ───────────────────────────────────────────────────────────────────╮
+Addressed both findings from the third independent review.
+
+Changes:
+- Fixed per-result error counting in:
+  /home/ubuntu/ai-agent-book/chapter9/hermes-self-evolution/worktree/hermes-agent/agent/trajectory.py
+  - A recognized payload now computes one combined failure boolean.
+  - Top-level and nested success: false can no longer double-count.
+- Updated mini_swe_runner.py to use the shared build_trajectory_entry() contract for:
+  - run_task() results.
+  - Successful batch JSONL output.
+  - Batch error records.
+- Preserved existing Mini-SWE fields, filenames, flush behavior, and error handling.
+- Added regression coverage in:
+  /home/ubuntu/ai-agent-book/chapter9/hermes-self-evolution/worktree/hermes-agent/tests/agent/test_trajectory.py
+  - Per-result error count invariant.
+  - Mini-SWE shared evaluation contract.
+- Searched for equivalent direct trajectory persistence sites. The report now documents the exact scope:
+  - agent/trajectory.py
+  - run_agent.py
+  - batch_runner.py
+  - mini_swe_runner.py
+- Unrelated conversations fields in MCP, session, audit, gateway, plugin, and compression artifacts were deliberately left unchanged.
+- Updated:
+  /home/ubuntu/ai-agent-book/chapter9/hermes-self-evolution/worktree/hermes-agent/BOOK_SELF_EVOLUTION_REPORT.md

+The claim boundary remains unchanged: this verifies metadata consistency and conservative signal extraction only. No downstream task-success benefit is claimed without the proposed ablation campaign.
