## 1. Executive Summary

This report establishes deterministic whole-loop evidence for the **Capability Preservation and Autonomous Improvement Subsystem** in `klbr`, directly addressing Review Findings R1, R2, and R3 (`REVIEW.md`, `NEXT-SWARM.md`).

Key achievements in this response:
1. **Replacement of Hand-Wired Gate with Live Daemon Scenario (R1, Assignment C):**
   - Stripped whole-loop claims from the old component integration test (`component_maintenance_dispatch_tests::test_component_maintenance_boundaries_with_manual_dispatch`), keeping it as honest component evidence.
   - Implemented `test_w6_full_daemon_orchestration_gate` driving the real `serve_listener` daemon entrypoint with a real WebSocket client (`tokio-tungstenite`) submitting normal operator stimuli.
   - Uses zero hand-invocations of the scheduler, claim, completion, prompt assembly, or candidate activation: the daemon's periodic 50ms driver automatically scans ready sessions, claims work items, issues maintenance prompts, executes model-returned tool calls in isolated workbenches, and coordinates host activation.
2. **First-Class Agent Origination Creating Runnable Work (R2, Assignment A & B):**
   - Python runtime `originate_maintenance` and host `HostRequest::MaintenanceOriginate` call `store.commit_origination_with_work(...)` in a single atomic transaction.
   - Creates a durable `WorkItem` with `status: pending`, `purpose: "repair"`, `cause: RunCause::MaintenanceReady` without requiring subsequent human input.
   - Bounded scoped evidence resolution (`resolve_evidence`) and workspace identity (`workspace_info`) are exposed through standard context APIs.
3. **Idempotent Observation & Preserved Claims (R3, Assignment A):**
   - Added SQLite migration `004_observations.sql` creating `observed_occurrences` mapping `occurrence_id` to `case_id`.
   - `Store::commit_observation_case_with_cursor` takes typed `&OccurrenceId`. Duplicate deliveries of the same occurrence are recognized as `ObserveResult::AlreadyObserved` without incrementing case count, clobbering active claim holders, or reopening completed items.
   - `Store::claim_work_item` returns typed `ClaimResult` and `complete_work_item` returns `RetireResult`, preventing silent boolean failures.
4. **All 3 Review 5 Authored Regressions Pass:**
   - `review5_observer_redelivery_preserves_claim_and_unique_occurrence`: PASS
   - `review5_observer_redelivery_does_not_reopen_completed_work`: PASS
   - `review5_agent_originated_request_creates_runnable_work`: PASS
5. **Real TypeScript Client Verification Over Live & Replay Paths:**
   - Canonical flat diagnostic records feed into actual `StreamingClientV2` from `klbr-web/src/lib/streaming-v2.ts`.
   - `healthStore`, `workItemsStore`, and `candidateStore` populate cleanly.
   - Strict lane purity: speech lane contains exactly 0 diagnostic entries.

## 2. Honest Four-Label Capability Matrix (Hard Rule 3)

Every capability preservation boundary is evaluated against the mandatory four honesty labels:
- **(a) Source/Helper Implemented:** Production code and non-test caller exist.
- **(b) Deterministic End-to-End Executed:** Automated test executes the full path from stimulus to verification.
- **(c) Real-Model Authored:** Candidate code authored autonomously by a real model without scripted templates.
- **(d) Later Observed Benefit:** Longitudinal performance improvement measured on downstream tasks.

| Step / Boundary | (a) Implemented | (b) Deterministic E2E | (c) Real-Model Authored | (d) Observed Benefit | Production Call Site |
|---|---|---|---|---|---|
| **Step 1: Normal Tool & Recovered Failure Observation** | YES | YES | NOT RUN | NOT RUN | `klbr-daemon/src/daemon.rs:915` (`observe_recovered_error`), `klbr-runtime/src/session.rs:370` |
| **Step 2: Durable Work Item & Boundary Restart** | YES | YES | NOT RUN | NOT RUN | `klbr-runtime/src/store.rs:1360` (`commit_origination_with_work`), `004_observations.sql` |
| **Step 3: Live Driver/Selector Claims Work** | YES | YES | NOT RUN | NOT RUN | `klbr-daemon/src/daemon.rs:1145` (periodic driver), `klbr-daemon/src/daemon.rs:720` (`claim_work_item`) |
| **Step 4: Provider Emits Python Candidate Tool Calls** | YES | YES | NOT RUN (Scripted) | NOT RUN | `klbr-core/src/runtime_turn/mod.rs:850` (`run_turn_loop_with_purpose`) |
| **Step 5: Host Candidate Validation & Activation** | YES | YES | NOT RUN | NOT RUN | `klbr-runtime/src/session.rs:344` (`activate_candidate`), `klbr-runtime/src/store.rs:880` |
| **Step 6: Real Restart with New Host/Registry** | YES | YES | NOT RUN | NOT RUN | `klbr-daemon/src/session_registry.rs:342` (`SessionRegistry::get_or_open`), `SessionRuntime::start` |
| **Step 7: Canonical Records to Real TypeScript Client** | YES | YES | NOT RUN | NOT RUN | `klbr-daemon/src/daemon.rs:65` (`project_event`), `klbr-web/src/lib/streaming-v2.ts:446` |

## 3. Detailed Verification of the 7 Gate Boundaries

### Boundary 1: Locally Recovered Failure & Normal Stimulus
- Stimulus sent as ordinary `V2ClientMsg::SendInput` over WebSocket.
- The execution writes a recoverable error to `stderr` (`CellOutputStream::Stderr`) while completing successfully (`CellStatus::Ok`).
- The agent originates maintenance for the friction using `originate_maintenance("repair", "capability mismatch in git.diff", ["event:1"], "critical")`.

### Boundary 2: Durable Work Item & Restart at Boundary
- Host atomically writes the origination event and durable `WorkItem` under an immediate SQLite transaction.
- Work item has `status: WorkStatus::Pending`, `purpose: "repair"`, `cause: RunCause::MaintenanceReady`.
- Daemon is stopped, connections dropped, and the store is reopened fresh. The work item survives the restart intact.

### Boundary 3: Live Driver / Selector Claim
- When restarted, the daemon's background periodic driver (50ms tick) calls `sessions_with_pending_work()`.
- Dispatches `trigger_session_turn_with_soul`.
- Invokes `select_next_work_item`, claims the work item via `Store::claim_work_item`, and verifies `claim.is_claimed()`.
- Captures the provider request: purpose `repair` and evidence ref `event:1` are verified in the captured payload.

### Boundary 4: Scripted Provider Tool Calls
- Mock LLM emits function tool call `python` executing:
  1. `resolve_evidence(["event:1"])` - resolves original event data.
  2. `Draft.from_directory(repo / "behavior")` - loads isolated staging candidate.
  3. Applies semantic policy edit to `klbr_hooks/defaults.py` (adding allowed source for maintenance).
  4. `draft.test()` - runs dry-run checks.
  5. `validated.publish(releases_dir)` - writes immutable release directory.
  6. `release.activate(expected_epoch=1)` - calls host RPC.

### Boundary 5: Host Validation & Activation Receipts
- Host validates manifest, hook slots (`attention.plan`, `delivery.review`), executes CAS update in SQLite, increments epoch to 2, and emits `hooks.activated`.
- Work item status transitions to `Completed` with disposition `"repaired"`.

### Boundary 6: REAL Restart (No Cached Entry)
- Daemon 2 is shut down, dropped, and a brand new `SessionRegistry` is initialized on `db_path`.
- `registry3.get_or_open` opens a fresh session.
- Post-restart session policy reflects epoch 2 and the repaired release hash.
- An ordinary new cell executes on the fresh workbench, verifying live execution on the new release.

### Boundary 7: Real TypeScript Client Ingestion (Live & Replay)
- The daemon's projected records are fed into actual `StreamingClientV2` via Node test harness.
- Verification confirms:
  - `healthStore.length === 1` (`git.diff` healthy)
  - `workItemsStore.length === 1` (work item with purpose `repair`)
  - `candidateStore.candidate_id === "230bd84f..."` (activated candidate)
  - `speechStore.length === 0` (strict lane purity, no diagnostic leakage)
  - Replay from sequence cursor yields identical store state.

## 4. Negative Test Matrix

All 7 required negative scenarios pass in `klbr-daemon/tests/v2_integration_test.rs`:

1. `test_negative_duplicate_observation_before_and_after_completion`:
   - Redelivery of same occurrence before claim keeps `WorkStatus::Pending` and leaves case count at 1.
   - Redelivery of same occurrence after completion keeps `WorkStatus::Completed` and does not reopen work.
2. `test_negative_failed_claim_refused_and_halts_inference`:
   - Second claim on already-claimed work returns `ClaimResult::AlreadyClaimed`. Inference does not run. Original claim holder preserved.
3. `test_negative_origination_commit_failure_rolls_back`:
   - Foreign key constraint failure rolls back transaction; no orphaned events or work items created.
4. `test_negative_unavailable_evidence_reported_honestly`:
   - Requesting nonexistent refs returns typed `unavailable` list with `"not_found"` reasons; never crashes or invents records.
5. `test_negative_candidate_test_failure_prevents_publication`:
   - Candidate with invalid manifest missing required slots fails `Release::publish` validation; no release directory created.
6. `test_negative_failed_activation_preserves_active_epoch`:
   - Activation with mismatched expected epoch fails CAS conflict; active epoch remains unchanged.
7. `test_negative_interruption_defers_cleanly`:
   - Interrupted/yielded maintenance transitions to `WorkStatus::Deferred`, remaining in `pending_work_items` for subsequent wake without losing history.

| `review5_observer_redelivery_does_not_reopen_completed_work` | Redelivery does not clear completion disposition or reopen completed items | PASS | 0.04s |
| `review5_agent_originated_request_creates_runnable_work` | `originate_maintenance` produces runnable work item without human stimulus | PASS | 0.13s |

## 6. Residual Scope & Honest Disclosures

Per Hard Rule 3 and reviewer guidelines:
1. **Real Model Authorship is NOT RUN:** In this milestone, candidate authoring was performed by a scripted mock LLM emitting Python tool calls. Autonomous repair generation by a live frontier model was not evaluated and must be labeled NOT RUN.
2. **Longitudinal Benefit is NOT RUN:** Multi-turn drift and longitudinal benchmark preservation across dozens of sessions were not measured in this unit/integration test suite.
3. **No Unwired Architecture:** No secondary schedulers, shadow daemons, or mock registries were introduced. All testing targets the single production path (`serve_listener`, `Store`, `SessionRegistry`, `SessionRuntime`).
