## Spec Compliance Matrix

| Requirement | Scenario | Test / Evidence | Result |
|-------------|----------|-----------------|--------|
| Slash Session Discoverability Family Registration | List resolves as raw args of `/session` | `session_commands::registry::tests::dispatch_routes_session_list_as_raw_args_on_canonical_command` | ✅ COMPLIANT |
| Slash Session Discoverability Family Registration | List is not registered as a standalone canonical command | `session_commands::registry::tests::default_registry_exposes_built_in_descriptors` | ✅ COMPLIANT |
| Centralized Dispatch Through the Pre-Execution Seam | Supported `/session` family forms use the shared seam | `pre_execution::tests::ingress_classifies_session_list_through_shared_seam` | ✅ COMPLIANT |
| Centralized Dispatch Through the Pre-Execution Seam | Unsupported `/session` subcommand stays inside the family handler boundary | `pre_execution::tests::ingress_keeps_unsupported_session_subcommands_inside_family_handler_boundary` | ✅ COMPLIANT |
| Session Discoverability Root Help | Root help includes `/session list` without mutation | `session_commands::service::tests::session_root_help_returns_discoverability_guidance_without_mutation` | ✅ COMPLIANT |
| Caller-Scoped Session List Discoverability | Session list returns only caller-visible rows in deterministic order | `session_commands::service::tests::session_list_returns_caller_scoped_rows_in_desc_order_with_balanced_output`; `memory::sqlite::tests::list_session_rows_for_scope_filters_by_scope_and_excludes_ended_sessions`; `memory::sqlite::tests::list_session_rows_for_scope_derives_lifecycle_and_resumable_authoritatively` | ✅ COMPLIANT |
| Caller-Scoped Session List Discoverability | Stable tiebreaker preserves repeated ordering for equal activity timestamps | `memory::sqlite::tests::list_session_rows_for_scope_uses_last_activity_then_id_desc_ordering` | ✅ COMPLIANT |
| Caller-Scoped Session List Discoverability | Missing caller-scope context does not broaden visibility | `session_commands::service::tests::session_list_requires_caller_scope` | ✅ COMPLIANT |
| Caller-Scoped Session List Discoverability | Empty caller-visible set still returns balanced read-only output | `session_commands::service::tests::session_list_returns_empty_success_for_scope_with_no_visible_sessions` | ✅ COMPLIANT |

**Compliance summary**: 9/9 scenarios compliant

## Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|------------|--------|-------|
| Canonical `/session` family registration | ✅ Implemented | `clients/agent-runtime/src/session_commands/registry.rs` registers only `/session` with `OptionalText`; descriptor inspection asserts `/session list` is not separately registered. |
| Shared ingress seam | ✅ Implemented | `clients/agent-runtime/src/pre_execution/mod.rs` still dispatches through `default_registry().dispatch(...)`; no transport-local `/session list` branch added. |
| Caller-scope seam preservation | ✅ Implemented | `SessionHandler` now calls `service.handle_session(&context, ...)`, and `handle_session_list` reads `context.caller.scope_key()`. |
| Scope enforcement and visibility | ✅ Implemented | `handle_session_list` denies missing caller scope and `SqliteMemory::list_session_rows_for_scope(...)` filters on `s.token_hash IS ?caller_scope_key`. |
| Ordering and stable tiebreak | ✅ Implemented | SQLite query orders by `s.last_activity DESC, s.id DESC`. |
| Minimal row shape | ✅ Implemented | `SessionListEntry` contains only `id`, `last_activity`, `lifecycle`, `resumable`. |
| Balanced output | ✅ Implemented | Service formats human summary from the same `sessions` vector used in `SessionCommandSuccessData::SessionList`. |
| Scope boundaries / non-goals | ✅ Implemented | `/session` only accepts exact raw args `status`, `inspect`, `list`; extra tokens are invalid, fixed `limit=50` and `offset=0` are internal only, and `handle_session_list` performs no mutation calls. |
| Existing `/session` status/inspect intact | ✅ Implemented | Existing status/inspect branches remain separate and regression tests pass. |

---

## Coherence (Design)

| Decision | Followed? | Notes |
|----------|-----------|-------|
| Widen only the `/session` service seam | ✅ Yes | Implemented exactly via `handle_session(&CommandContext, raw_args)`. |
| Dedicated read-only session-list query | ✅ Yes | New `list_session_rows_for_scope(...)` contract added instead of reusing `/resume` listing. |
| Lifecycle derivation aligned with existing semantics | ✅ Yes | SQLite derives `suspended` only from `session_state.lifecycle_state = 'suspended'`; otherwise `active`; ended rows excluded. |
| Resumable derived from authoritative current capability | ✅ Yes | Query requires the lifecycle to be suspended, latest compact snapshot reference, existing snapshot row, and `is_resume_capable = 1`. |
| Balanced output at service boundary | ✅ Yes | Message and structured payload share the same row model. |
| File changes table alignment | ✅ Yes | All planned runtime files and both delta specs are present and modified consistently with design scope. |

## Issues Found

**CRITICAL**: None

**WARNING**: None

**SUGGESTION**: None

## Verdict

PASS

Implementation matches proposal, both spec deltas, design, and completed tasks for the approved `/session list` slice, with focused runtime evidence and no scope creep detected.
