## Validation Execution

### Commands run

- `cargo fmt --manifest-path clients/agent-runtime/Cargo.toml --all -- --check` → ✅ passed
- `cargo clippy --manifest-path clients/agent-runtime/Cargo.toml --all-targets -- -D warnings` → ✅ passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml adapt_handled_ingress_ -- --nocapture` → ✅ 5 passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml cli_session_commands_are_handled_before_agent_execution -- --nocapture` → ✅ 1 passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml cli_unknown_slash_like_input_falls_through -- --nocapture` → ✅ 1 passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml canonical_outcome_early_response_ -- --nocapture` → ✅ 4 passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml web_chat_stream_returns_ -- --nocapture` → ✅ 2 passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml web_chat_stream_unknown_slash_like_input_falls_through_to_provider_execution -- --nocapture` → ✅ 1 passed
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml execute_ -- --nocapture` → ✅ relevant slash-webhook tests passed, including success, permission-denied, and unknown-fallthrough regressions
- `cargo test --manifest-path clients/agent-runtime/Cargo.toml ingress_outcome_ -- --nocapture` → ✅ 5 passed

Relevant behavioral evidence now includes:

- HTTP `/webhook`: success, permission-denied, and unknown slash-like fallthrough
- `/web/chat/stream`: success, generic error, and unknown slash-like fallthrough
- webhook dispatcher: success, permission-denied, and unknown slash-like fallthrough
- channel ingress: pre-memory short-circuit, plan-mode handling, success, permission-denied, and unknown slash-like fallthrough

### Build / type check

Skipped intentionally. `openspec/config.yaml` does not define a `build_command`, and `design.md` explicitly says not to add a build step for this slice.

### Coverage

Not configured in `openspec/config.yaml`.

## Spec Compliance Matrix

| Requirement | Scenario | Evidence | Result |
|---|---|---|---|
| Shared Handled Slash Outcome Adaptation Contract | Supported transports share one handled-success adaptation boundary | Adapter success unit test passes; HTTP `/webhook`, `/web/chat/stream`, webhook dispatcher, and channel success regressions pass. No CLI success-path regression was found. | ⚠️ PARTIAL |
| Shared Handled Slash Outcome Adaptation Contract | Permission-denied failures stay machine-readable across all supported transports | Adapter permission-classification unit test passes; HTTP `/webhook`, webhook dispatcher, and channel permission-denied regressions pass. No CLI or SSE permission-denied regression was found. | ⚠️ PARTIAL |
| Shared Handled Slash Outcome Adaptation Contract | Unknown slash-like input falls through consistently without transport-local recognition branches | CLI, HTTP `/webhook`, `/web/chat/stream`, webhook dispatcher, and channel fallthrough regressions all pass; `main.rs` no longer uses a pre-dispatch `recognizes(...)` gate. | ✅ COMPLIANT |
| Shared Handled Slash Outcome Adaptation Contract | Blocking outcomes remain shared internally while outward wrappers stay transport-specific | `pre_execution::tests::adapt_handled_ingress_preserves_blocking_outcomes` passes and transport code preserves transport-local wrappers, but no transport-level slash-triggered blocking regression was found. | ⚠️ PARTIAL |
| Centralized Dispatch Through the Pre-Execution Seam | CLI/runtime fast path uses the shared seam without a transport-local recognition gate | `main.rs::maybe_handle_cli_session_command(...)` routes through `evaluate_ingress(...)` + `adapt_handled_ingress(...)`; handled and fallthrough CLI regressions pass. | ✅ COMPLIANT |
| Centralized Dispatch Through the Pre-Execution Seam | Supported transports preserve one ingress dispatch path for recognized commands | CLI/runtime, gateway HTTP, gateway SSE, webhook dispatch, and channel ingress all consume the shared seam and adapter; targeted regressions pass across those surfaces. | ✅ COMPLIANT |
| Transport Parity for Recognized Slash Commands | Supported transports share dispatch and handled adaptation while keeping caller semantics explicit | Shared adapter is used everywhere and typed-context tests preserve caller semantics; runtime evidence is strong for HTTP/SSE/webhook/channel but still incomplete for CLI success/denial parity and slash-blocking transport behavior. | ⚠️ PARTIAL |
| Transport Parity for Recognized Slash Commands | Transport parity remains internal and does not unify outward envelopes | Code paths and regressions preserve transport-specific JSON, SSE, webhook, and channel wrappers instead of unifying envelopes. | ✅ COMPLIANT |

## Correctness (Static)

| Requirement | Status | Notes |
|---|---|---|
| Shared handled-result contract after `evaluate_ingress(...)` | ✅ Implemented | `pre_execution/session_command_adapter.rs` introduces `HandledIngress`, `HandledIngressOutcome`, `SessionCommandFailureClass`, and `adapt_handled_ingress(...)`. |
| Shared transport adoption | ✅ Implemented | CLI/runtime, gateway HTTP, gateway SSE, webhook dispatch, and channel ingress all consume `adapt_handled_ingress(...)`. |
| Remove CLI pre-recognition branch | ✅ Implemented | `main.rs::maybe_handle_cli_session_command(...)` calls the seam directly and no longer uses `default_registry().recognizes(...)`. |
| Preserve transport-specific envelopes | ✅ Implemented | HTTP JSON, SSE events/status, webhook result shape, CLI strings, and channel text remain transport-local wrappers. |

## Coherence (Design)

| Decision | Followed? | Notes |
|---|---|---|
| Place shared adaptation helper in `pre_execution` | ✅ Yes | New adapter module lives under `clients/agent-runtime/src/pre_execution/` and is re-exported from `mod.rs`. |
| Normalize only internal handled results | ✅ Yes | Shared contract is internal only; outward envelopes remain transport-specific. |
| Collapse permission-style failures into one shared denial class while preserving source kind | ✅ Yes | Adapter maps `MissingCallerScope` and `PermissionDenied` to `SessionCommandFailureClass::PermissionDenied` while preserving the original `failure.kind`. |
| File changes align with design table | ✅ Yes | Expected runtime files and tests were updated; new adapter file was added. |

## Issues Found

### CRITICAL

None.

### WARNING

1. Behavioral proof is still partial for full all-transport success parity because no CLI success-path regression was found for a recognized slash command.
2. Behavioral proof is still partial for full all-transport permission-denied parity because no CLI or gateway SSE permission-denied regression was found.
3. Blocking-outcome transport evidence remains partial: the shared adapter proves blocking classification, but there is still no transport-level regression demonstrating a slash-driven blocking outcome through HTTP, SSE, webhook dispatch, or channels.

### SUGGESTION

1. Add one CLI success regression, one SSE permission-denied regression, and—if a slash command can legitimately yield blocking at runtime—one transport-level blocking regression to close the remaining parity-proof gaps.

## Verdict

PASS WITH WARNINGS

The implementation now satisfies the formatting, lint, and targeted runtime validation gates, and the newly added HTTP `/webhook`, webhook dispatcher, channel `/resume`, and `/web/chat/stream` fallthrough regressions materially strengthen spec coverage. Remaining gaps are evidence gaps around complete all-transport success/denial parity and slash-driven blocking behavior, not failing behavior in the validated paths.
