Salvage of PR #16100 onto current main (after emozilla's #17514 fix that unblocks plugin Pydantic body validation). History preserved on the standing `feat/kanban-standing` branch; this squashes the 22 iterative commits into one clean landing. What this lands: - SQLite kernel (hermes_cli/kanban_db.py) — durable task board with tasks, task_links, task_runs, task_comments, task_events, kanban_notify_subs tables. WAL mode, atomic claim via CAS, tenant-namespaced, skills JSON array per task, max-runtime timeouts, worker heartbeats, idempotency keys, circuit breaker on repeated spawn failures, crash detection via /proc/<pid>/status, run history preserved across attempts. - Dispatcher — runs inside the gateway by default (`kanban.dispatch_in_gateway: true`). Ticks every 60s, reclaims stale claims, promotes ready tasks, spawns `hermes -p <assignee> chat -q "work kanban task <id>"` with HERMES_KANBAN_TASK + HERMES_KANBAN_WORKSPACE env. Auto-loads `--skills kanban-worker` plus any per-task skills. Health telemetry warns on stuck ready queue. - Structured tool surface (tools/kanban_tools.py) — 7 tools (kanban_show, kanban_complete, kanban_block, kanban_heartbeat, kanban_comment, kanban_create, kanban_link). Gated on HERMES_KANBAN_TASK via check_fn so zero schema footprint in normal sessions. - System-prompt guidance (agent/prompt_builder.py KANBAN_GUIDANCE) injected only when kanban tools are active. - Dashboard plugin (plugins/kanban/dashboard/) — Linear-style board UI: triage/todo/ready/running/blocked/done columns, drag-drop, inline create, task drawer with markdown, comments, run history, dependency editor, bulk ops, lanes-by-profile grouping, WS-driven live refresh. Matches active dashboard theme via CSS variables. - CLI — `hermes kanban init|create|list|show|assign|link|unlink| claim|comment|complete|block|unblock|archive|tail|dispatch|context| init|gc|watch|stats|notify|log|heartbeat|runs|assignees` + `/kanban` slash in-session. - Worker + orchestrator skills (skills/devops/kanban-worker + kanban-orchestrator) — pattern library for good summary/metadata shapes, retry diagnostics, block-reason examples, fan-out patterns. - Per-task force-loaded skills — `--skill <name>` (repeatable), stored as JSON, threaded through to dispatcher argv as one `--skills X` pair per skill alongside the built-in kanban-worker. Dashboard + CLI + tool parity. - Deprecation of standalone `hermes kanban daemon` — stub exits 2 with migration guidance; `--force` escape hatch for headless hosts. - Docs (website/docs/user-guide/features/kanban.md + kanban-tutorial.md) with 11 dashboard screenshots walking through four user stories (Solo Dev, Fleet Farming, Role Pipeline, Circuit Breaker). - Tests (251 passing): kernel schema + migration + CAS atomicity, dispatcher logic, circuit breaker, crash detection, max-runtime timeouts, claim lifecycle, tenant isolation, idempotency keys, per- task skills round-trip + validation + dispatcher argv, tool surface (7 tools × round-trip + error paths), dashboard REST (CRUD + bulk + links + warnings), gateway-embedded dispatcher (config gate, env override, graceful shutdown), CLI deprecation stub, migration from legacy schemas. Gateway integration: - GatewayRunner._kanban_dispatcher_watcher — new asyncio background task, symmetric with _kanban_notifier_watcher. Runs dispatch_once via asyncio.to_thread so SQLite WAL never blocks the loop. Sleeps in 1s slices for snappy shutdown. Respects HERMES_KANBAN_DISPATCH_IN_GATEWAY=0 env override for debugging. - Config: new `kanban` section in DEFAULT_CONFIG with `dispatch_in_gateway: true` (default) + `dispatch_interval_seconds: 60`. Additive — no \_config_version bump needed. Forward-compat: - workflow_template_id / current_step_key columns on tasks (v1 writes NULL; v2 will use them for routing). - task_runs holds claim machinery (claim_lock, claim_expires, worker_pid, last_heartbeat_at) so multi-attempt history is first- class from day one. Closes #16102. Co-authored-by: emozilla <emozilla@nousresearch.com>
