feat(kanban): durable multi-profile collaboration board (#17805)
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.
