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_preserves_claim_and_unique_occurrence	Redelivery does not overwrite active claim or duplicate occurrence count	PASS	0.05s
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).
