# Hivemind Documentation Parity Status

## Final Parity Sweep — Complete 

Sweep performed against all files in `docs/design/` and `docs/architecture/`.

---

## CLI Operational Semantics (`docs/design/cli-operational-semantics.md`)

### Section 2: Project Commands 
- **project create** — Implemented with `--description` support
- **project list** — Implemented with `--format json|table|yaml`
- **project attach-repo** — Implemented with `--name` and `--access` options

### Section 3: Task Commands 
- **task create** — Implemented with `--description`, `--scope` support
- **task list** — Implemented with `--state` filter and format support
- **task close** — Implemented with active-flow precondition check
- **task inspect** — Implemented
- **task update** — Implemented

### Section 4: TaskGraph Commands 
- **graph create** — Implemented with `--from-tasks` (multiple IDs)
- **graph add-dependency** — Implemented with cycle detection, idempotent
- **graph validate** — Implemented (read-only, returns valid/invalid + issues)

### Section 5: TaskFlow Commands 
- **flow create** — Implemented, locks graph, emits TaskFlowCreated
- **flow start** — Implemented, schedules ready tasks, emits TaskFlowStarted + TaskReady
- **flow pause** — Implemented with `--wait` option
- **flow resume** — Implemented with state validation
- **flow abort** — Implemented with `--force` and `--reason`
- **flow status** — Implemented with json/table/yaml format

### Section 6: Task Execution Commands 
- **task retry** — Implemented with `--reset-count`, retry limit enforcement
- **task abort** — Implemented, idempotent on Failed tasks
- **attempt inspect** — Implemented (read-only, shows task execution state in flow)

### Section 7: Verification Commands 
- **verify override** — Implemented with `pass`/`fail` decision, emits HumanOverride event

### Section 8: Merge Commands 
- **merge prepare** — Implemented, requires completed flow, idempotent
- **merge approve** — Implemented, requires prepared merge with no conflicts, idempotent
- **merge execute** — Implemented, requires approved merge, emits MergeCompleted

### Section 9: Event Commands 
- **events list** — Implemented with `--project` filter and `--limit`
- **events inspect** — Implemented (shows full event detail)
- **events stream** — Implemented with `--flow`, `--task`, `--project`, `--graph` filters
- **events replay** — Implemented with `--verify` (compares replayed vs current state)

### Section 10: Output Contracts 
- **--format json|table|yaml** — All three formats supported across all commands
- **Structured error output** — JSON/YAML error responses with code, message, details
- **Exit codes** — 0=success, 1=error, 2=not_found, 3=conflict (mapped from error codes)

### Section 11: Invariants 
- Every command has defined preconditions enforced in Registry
- Effects only occur if preconditions met
- Failures reported with structured HivemindError
- Idempotence behavior matches docs for all commands
- Events emitted for all state-changing operations

---

## Event Model (`docs/architecture/hivemind_event_model.md`) 

All event categories relevant to CLI commands are implemented:
- **Project Events**: ProjectCreated, ProjectUpdated, RepositoryAttached, RepositoryDetached
- **TaskGraph Events**: TaskGraphCreated, TaskAddedToGraph, DependencyAdded, ScopeAssigned
- **TaskFlow Lifecycle**: TaskFlowCreated, Started, Paused, Resumed, Completed, Aborted
- **Task Scheduling**: TaskReady, TaskBlocked
- **Task Execution**: TaskExecutionStateChanged, TaskRetryRequested, TaskAborted
- **Verification/Human**: HumanOverride
- **Merge Events**: MergePrepared, MergeApproved, MergeCompleted

Event replay is deterministic and idempotent (tested).

---

## State Model (`docs/architecture/hivemind_state_model.md`) 

All state layers implemented:
- **Project State** — Projects with identity, repositories, configuration
- **TaskGraph State** — Static DAG with tasks, dependencies, retry policies, scopes
- **TaskFlow State** — Runtime instance with lifecycle (Created/Running/Paused/Completed/Aborted)
- **TaskExecution State** — Per-task FSM (Pending/Ready/Running/Verifying/Success/Retry/Failed/Escalated)
- **MergeState** — Merge workflow tracking (Prepared/Approved/Completed)

All state derived from events via `AppState::replay()`.

---

## Error Model (`docs/design/error-model.md`) 

- **Structured errors**: HivemindError with category, code, message, origin, recoverable, recovery_hint, context
- **Error categories**: System, Runtime, Agent, Scope, Verification, Git, User, Policy
- **Exit code mapping**: Error codes mapped to CLI exit codes per Section 10.3
- **Recovery hints**: Supported via `with_hint()` builder

---

## Event Replay Semantics (`docs/design/event-replay-semantics.md`) 

- **Full state reconstruction**: `AppState::replay(events)` → orchestration state
- **Determinism**: Same events → same state (tested)
- **Idempotence**: Multiple replays produce identical results (tested)
- **CLI replay**: `events replay <flow-id> --verify` compares replayed vs stored state

---

## TaskFlow Specification (`docs/architecture/hivemind_task_flow.md`) 

- **Graph Scheduler**: Dependency-based task readiness via Scheduler
- **Task Execution FSM**: All 7 states + valid transitions implemented
- **Control Plane**: Pause/resume/abort with human override support
- **Retry Policy**: max_retries enforcement, --reset-count override

---

## CLI Capability Specification (`docs/architecture/hivemind_cli_capability_specification.md`)

### Implemented 
- System introspection (version)
- Event access (stream, query, replay)
- Project management (create, list, inspect, update, attach-repo)
- Task management (create, update, list, inspect, close)
- TaskGraph & Planning (create, add tasks, add dependencies, validate)
- TaskFlow execution (create, start, pause, resume, abort, status)
- Task-level control (retry, abort, attempt inspect)
- Verification control (override)
- Merge & Integration (prepare, approve, execute)
- Output contracts (json, table, yaml)

### Out of Scope (requires runtime/agent integration) 
- Runtime selection/diagnostics (Section 11) — needs actual runtime adapters
- Execution branch/checkpoint/diff commands (Section 9) — needs git worktree integration
- Planner invocation (Section 5.2) — needs agent framework
- Automation/scheduling (Section 12) — future feature
- Agent assignment (Section 4.2) — needs agent framework
- Scope inspection/conflict handling (Section 8) — partially implemented via graph validate
