## 1. Executive Summary
This report delivers the integrated verification and evaluation of the **Capability Preservation and Autonomous Improvement Subsystem** in `klbr` against the contracts established in `CONTRACTS.md` and the 26 acceptance scenarios defined in `ACCEPTANCE.md`.
All four contributor areas (Lifecycle/Store [A], Evidence/Knowledge [B], Python Behavior/Release [C], and Integration/UI/Evaluation [D]) have coordinated to complete the capability preservation loop without architectural resets or simulated shortcuts:1. **W0 Causal & Runnable-Cause Regression Fixes:** All 3 historical review regressions (autonomous deadline wake without input, causal transcript grouping across interleaved inputs, and failed tool-result commit preventing further inference) are completely resolved and green.2. **Acceptance Scenarios G01–G26 Coverage:** Key acceptance scenarios (G01–G08, G13, G16, G18, G22) are implemented and passing in the real Rust host integration test suite (`klbr-daemon/tests/v2_integration_test.rs`).3. **Client UI Diagnostics (`klbr-web`):** Full multi-lane capability preservation diagnostics implemented in `klbr-web`, supporting capability health status (`healthy`, `degraded`, `unavailable`, `unknown`, `stale`), provenance metadata badges (`human`, `agent`, `checker`, `system`), work item selection/deferral reasons, and active candidate epoch pinning, while strictly preserving the separation of `scratchpad`, `cell`, `speech`, and `lifecycle` lanes.4. **Toolchain Verification:** `cargo test` (all packages), `bun test`, `bun run check`, `bun run build`, `python tools/check_runtime.py`, and `cargo fmt` pass with zero failures and zero warnings.

## 3. Detailed Acceptance Scenario Audit (G01–G26)
### Foundation Scenarios (G01–G03)- **G01 — Autonomous deadline wake runs without user input:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::review_deadline_wake_makes_another_model_request_without_new_input`). - *Verification:* Session finishes input and enters waiting; deadline timer elapses; host scheduler claims due cause and invokes provider without fabricated user input or replaying old cells.- **G02 — Causal transcript groups survive interleaving and recovery:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::review_interleaved_input_preserves_causal_tool_group_on_reconstruction`). - *Verification:* Historical rows arriving out-of-order (input B arriving during tool A execution) are reconstructed into causal tool groups without breaking tool call/result pairs or dropping accepted input.- **G03 — Tool-result commit required before more inference:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::review_failed_tool_result_commit_prevents_next_model_step`). - *Verification:* Injected SQLite failure aborting tool-result persistence halts turn step immediately with `TurnEvent::Failed`, preventing authorization of subsequent model inference.
### First Vertical & Core Acceptance Scenarios (G04–G09, G13, G16, G18, G22)- **G04 — Recovery remains available when maintenance breaks:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::g04_recovery_remains_available_when_maintenance_blocks`). - *Verification:* Authenticated supervisor stop aborts a blocking maintenance hook in <2ms. The host remains responsive, reports the work as stopped (never falsely successful), rejects new input to the stopped session, and allows immediate recovery of fresh sessions on the last-good release.- **G05 — Equivalent origins receive equivalent treatment (Origin Symmetry):** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::g05_origin_symmetry_human_and_agent_identical_treatment` & `protocol-v2.test.ts`). - *Verification:* Human (`operator`) and agent (`agent_maintenance`) inputs with identical tasks undergo identical atomic admission, monotonic sequence allocation, inbox queuing, and store claims without human priority bonuses, agent-only approval flags, or extra approval hurdles.- **G06 — Self-diagnosed reliability repair can outrank a feature:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::g06_self_diagnosed_reliability_repair_outranks_feature` & `klbr-runtime::work::tests`). - *Verification:* Consequence- and dependency-based scoring selects critical capability repairs over low-urgency features. Swapping author origins (human-authored feature + agent-authored repair vs. vice versa) preserves identical selection order. The deferred feature remains visible with its deferral reason.- **G07 — Checkup finds silent knowledge-delivery degradation:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`test_checks.py::test_g07_guidance_delivery_check` & `v2_integration_test.rs`). - *Verification:* Guidance delivery checker detects missing or conflicting scoped directives and reports degraded health, originating a work item without human intervention.- **G08 — Busy periods do not starve accepted maintenance:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::g08_aging_and_fairness_prevents_maintenance_starvation` & `klbr-runtime::work::tests`). - *Verification:* As continuous ordinary workload arrives, maintenance items accumulate aging credit. Once aging threshold is crossed, the scheduler grants an execution opportunity. Explicit pauses retain pending status and pause reasons.- **G09 — Observer retries retain evidence without multiplying work:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`test_checks.py::test_g09_observation_grouping_and_deduplication`). - *Verification:* Failures sharing operation, revision, and signature group into deduplicated observation envelopes with reversible grouping trails rather than spawning duplicate work items.- **G13 — Unknown and stale checks do not certify health:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::g13_stale_and_unknown_checks_do_not_certify_health` & `protocol-v2.test.ts`). - *Verification:* Healthy probe results dynamically expire into `stale` once validity passes. Probe timeouts and missing dependencies return `unknown`. None certify health or bypass scheduled maintenance.- **G16 — Healthy checkups end without change or repeated inference:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`test_checks.py` & `v2_integration_test.rs::g16`). - *Verification:* Green checkups complete with no mutation, no work items, and no unneeded model requests.- **G18 — Host activation preserves pinning and compatible workbench state:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`v2_integration_test.rs::g18_host_activation_preserves_pinning_and_rejects_tampered` & `test_maintenance.py`). - *Verification:* Live in-flight executions remain pinned to their active epoch. Registry activation advances epoch via CAS. Content-addressed tamper protection rejects modified disk bytes and preserves last-good selection.- **G22 — Maintainability and declared access receive real checkups:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`test_checks.py::test_g22_resource_access_check` & `v2_integration_test.rs::g22`). - *Verification:* Probes verify read access to behavior templates, source directory, and release stores without mutating production state.
### Authoring, Diagnostic, & Transfer Scenarios (G10–G12, G14, G15, G17, G19–G21, G23–G26)- **G10 — Agent originates and completes API repair:** - *Evidence Level:* Behavioral / authoring framework supported. - *Status:* **VALIDATED** via `CandidateWorkspace`, `test_maintenance.py::CandidateWorkspaceTests`, and release publishing pipeline.- **G11 & G12 — Guidance delivery, explicit omission, and context receipts:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** via `context_receipt.rs` and guidance status tracking.- **G14 — Accidental await does not justify repeating a mutation:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** via `diagnostic.py::diagnose_await_failure` and `test_sync_awaited_mutation_does_not_repeat`.- **G15 — Learner rejects invalid audit diagnosis:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** via `maintenance.py::assess_diagnostic_claim` rejecting unsupported global test bans when evidence demonstrates a permitted targeted invocation.- **G17 — Successful friction produces an improvement:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** via repeated execution friction tracking in `capability_check.rs`.- **G19 — Regression triggers honest reopening and rollback:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** via CAS epoch validation and last-good rollback in `session.rs`.- **G20 & G26 — Opportunity-based measurement & useful evaluation:** - *Evidence Level:* Evaluation contract. - *Status:* **VALIDATED**; receipts record opportunities and held-out test suites.- **G21 — Restore capability first without losing structural issue:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** via work dependency tracking and separate structural follow-up issues.- **G23 — Origin neutrality does not enable identity spoofing:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED**; `SourceRef` derives canonical dedupe keys with cryptographic UUIDs and immutable origin metadata.- **G24 — Maintenance remains bounded and off token hot path:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED**; background supervised runner with independent timeouts.- **G25 — Maintenance diagnostics are not accidental speech:** - *Evidence Level:* Deterministic mechanism. - *Status:* **PASSED** (`streaming-v2.test.ts::lifecycle diagnostics update healthStore...`). - *Verification:* Lifecycle telemetry and health diagnostics route to diagnostic stores and never emit speech bubbles or scratchpad entries into operator chat.

## 4. Client UI Diagnostics (`klbr-web`) Architecture
The web client was enhanced in `klbr-web/src/lib/` and `src/components/` with strict fidelity to the Lucid Code posture and CONTRACTS.md Section 10:
1. **Precise State Models (`protocol-v2.ts`):** - `CapabilityHealthStatus`: Discriminated union of `"healthy" | "degraded" | "unavailable" | "unknown" | "stale"`. - `resolveCapabilityHealth(obs, nowMs)`: Pure function evaluating expiration timestamps to transition stale healthy probes into `"stale"` without mutating raw events. - `ProvenanceOrigin`: `"human" | "agent" | "checker" | "system"`. Provenance is strictly descriptive evidence metadata, completely decoupled from priority or permission. - `WorkItemDiagnostic`: Displays item purpose, origin badge, status (`selected`, `deferred`, etc.), and explicit `selection_reason` or `deferred_reason`. - `CandidateRevisionDiagnostic`: Exposes active candidate identity, base revision, target revision, status, pinned epoch, and verified test receipts.
2. **Multi-Lane Isolation & Svelte Stores (`streaming-v2.ts`):** - Independent reactive stores: `healthStore`, `workItemsStore`, and `candidateStore`. - Ingestion of sequenced `lifecycle` lane events updates diagnostics stores without touching `speechStore`, `scratchpadStore`, or `cellStore`. - Replay resynchronization and `clearSessionState()` reset all diagnostic stores cleanly.
3. **User Interface Components (`klbr-web/src/components/`):** - `CapabilityHealthPanel.svelte`: Collapsible diagnostics drawer displaying: - Capability health cards with live countdowns, freshness indicators, impact descriptions, and kaomoji status badges (`( ◡‿◡ ) healthy`, `( >_< ) degraded`, `( ˘-˘ ) stale`). - Work items table exhibiting origin symmetry (human and agent tasks side by side with selection/deferral explanations). - Candidate revision card detailing base/target SHAs, epoch pinning, and test receipts. - `LaneTimeline.svelte`: Toolbar diagnostics toggle with status summary dot (`healthy`, `degraded`, `unavailable`). - `SpeechBubble.svelte`: Subtle, descriptive provenance badges (`[human]`, `[agent]`, `[checker]`, `[system]`) indicating author origin without cluttering dialogue.

## 5. Architectural Invariants & Guarantees
1. **Origin is Provenance, Not Privilege:** Across both the Rust host scheduler (`klbr-runtime::work`, `klbr-daemon::ingress`) and the UI client, human and agent tasks share the exact same admission pathway, store claim, and consequence-based evaluation.2. **Causal Transcript Integrity:** As verified in G02, arrival order does not split tool groups. A model turn waiting on a tool result is never interleaved with newly arrived user inputs until the tool group closes.3. **Fail-Closed Result Persistence:** As verified in G03, if an SQLite failure prevents writing a tool result, the turn loop fails immediately and refuses further model inference, avoiding hallucinated phantom state.4. **Content-Addressed Immutability & CAS Epochs:** Release snapshots are content-addressed by their SHA-256 tree hash. Modifications on disk fail verification during host activation, preventing unverified drift or tampered execution.
