Follow-up to the previous commit's safe-int task_age fix.
The original PR shipped without test coverage. This commit adds:
- test_safe_int_accepts_int_and_int_string — sanity for the well-typed
path so the helper itself can't quietly start swallowing valid values.
- test_safe_int_returns_none_on_corrupt_inputs — the failure modes
(None, '%s', 'abc', '', '1.5', random objects). Covers both the
ValueError and TypeError catch branches.
- test_task_age_handles_corrupt_created_at — the headline regression:
a task with created_at='%s' used to raise ValueError and turn
GET /api/plugins/kanban/board into a 500.
- test_task_age_handles_corrupt_started_and_completed — confirms the
safe-int treatment is consistent across all three timestamp fields.
- test_task_age_well_formed_task — regression that the safe path
doesn't change observable output for normal data.
- test_task_dict_survives_corrupt_created_at — defense in depth.
Writes a corrupt row directly via SQL, reads it back through the
ORM, and confirms task_age + the surrounding plugin_api guard
degrade gracefully instead of crashing.
Also adds the AUTHOR_MAP entry for the contributor's GitHub-noreply
email so release notes credit @baocin (the commit was authored locally
as `aoi <aoi@hino.local>` — re-attributed during salvage to the
github noreply form).
Follow-up to the previous commit's contributor cherry-pick.
The cherry-picked change replaced the bare ``["hermes", ...]`` spawn with
``[sys.executable, "-m", "hermes", ...]``. The intent was right (avoid
PATH dependence — cron, systemd User= services, launchd jobs, and other
detached dispatcher invocations routinely run with a stripped $PATH that
doesn't include the venv's bin/, breaking the bare-shim spawn) but the
module name is wrong: there is no top-level ``hermes`` package. The
console-script entry point in pyproject.toml is
``hermes = "hermes_cli.main:main"``, and ``python -m hermes`` fails with
``No module named hermes``. The cherry-picked form would have replaced a
sometimes-broken spawn with an always-broken one.
This commit:
- Adds ``_resolve_hermes_argv()``, mirroring ``gateway.run._resolve_hermes_bin``.
Tries ``shutil.which("hermes")`` first (preferred — keeps existing ``ps``
output and log lines familiar in the common case) and falls back to
``[sys.executable, "-m", "hermes_cli.main"]`` when the shim is not on
PATH. The fallback goes through the running interpreter so it's
PATH-independent. Kept as a local helper rather than imported from
gateway because ``hermes_cli`` sits below ``gateway`` in the dependency
order.
- Switches the dispatcher's ``cmd`` list to use ``*_resolve_hermes_argv()``.
- Adds three regression tests:
* ``test_resolve_hermes_argv_prefers_path_shim`` — pins the PATH-first
branch so a future refactor doesn't silently flip the order.
* ``test_resolve_hermes_argv_falls_back_to_module_form_when_no_path_shim`` —
pins the correct module name (``hermes_cli.main``, NOT ``hermes``).
Direct regression guard for the form that shipped in the original PR.
* ``test_resolve_hermes_argv_module_actually_runs`` — runs the fallback
invocation as a real subprocess and asserts ``--version`` works, so
losing ``hermes_cli.main``'s ``__main__`` handling can't slip past the
string-match test.
Verified end-to-end: with the shim on PATH the resolver returns
``[/.../hermes]`` and ``--version`` works; with the shim removed the
resolver returns ``[python, -m, hermes_cli.main]`` and ``--version``
still works; the original PR's ``python -m hermes`` invocation fails as
expected (``No module named hermes``).
ALTER TABLE calls inside _migrate_add_optional_columns were guarded by a
snapshot of PRAGMA table_info taken at function entry. When the gateway
dispatcher opens the kanban DB twice per tick (once in _tick_once_for_board
and once via init_db's discard-and-reconnect path), a second connection can
run the same migration before the first one commits, causing:
sqlite3.OperationalError: duplicate column name: consecutive_failures
This crashed the dispatcher on every first tick after a gateway restart
(subsequent ticks succeeded because the columns were then present).
Fix: introduce _add_column_if_missing() which wraps ALTER TABLE in a
try/except that swallows OperationalError whose message contains
'duplicate column name'. All ALTER TABLE calls in
_migrate_add_optional_columns are routed through this helper.
Closes#21708
Enforce the parent-completion invariant at claim_task (the single
ready->running chokepoint) and re-gate unblock_task so blocked->ready
only fires when parents are done. Prevents child tasks from running
ahead of in-progress parents under the create-then-link race.
Also adds a stress test that races concurrent create+link against
hammered claim_task and asserts no child runs while any parent is undone.
Ref: kanban/boards/cookai/workspaces/t_a6acd07d/root-cause.md
Refs: t_8d6af9d6
Problem:
unlink_tasks() removes a parent→child dependency edge but does not trigger
recompute_ready(). A child whose last blocking parent is unlinked stays
stuck in 'todo' indefinitely — it only promotes to 'ready' on the next
dispatcher tick or a manual 'hermes kanban recompute'. For CLI-only users
without a dispatcher, the child is permanently stuck.
Root cause:
complete_task() and unblock_task() both call recompute_ready() after their
write transaction so downstream children are evaluated immediately.
unlink_tasks() was missing this call — removing a dependency is
semantically equivalent to completing one, so the same recompute is needed.
Fix:
Capture the rowcount result before the write_txn exits, then call
recompute_ready(conn) outside the transaction when a row was actually
deleted (so the child sees the updated task_links state).
Tests:
Added test_unlink_tasks_triggers_recompute_ready in
tests/hermes_cli/test_kanban_db.py: creates parent A (done) + parent C
(running), child B with both parents (todo), unlinks C→B, asserts B is
ready immediately. Stash-verified: FAILS without fix (child stays todo),
PASSES with fix.
62/62 tests green in tests/hermes_cli/test_kanban_db.py.
Closes#22459.
SQLite's WAL mode requires shared-memory (mmap) coordination and fcntl
byte-range locks that don't reliably work on network filesystems. Upstream
documents this explicitly:
https://www.sqlite.org/wal.html#sometimes_queries_return_sqlite_busy_in_wal_mode
On NFS / SMB / some FUSE mounts / WSL1, 'PRAGMA journal_mode=WAL' raises
'sqlite3.OperationalError: locking protocol' (SQLITE_PROTOCOL). Before
this change, every feature backed by state.db or kanban.db broke silently:
- /resume, /title, /history, /branch returned 'Session database not
available.' with no cause
- gateway logged the init failure at DEBUG (invisible in errors.log)
- kanban dispatcher crashed every 60s, driving the known migration race
(duplicate column name: consecutive_failures, #21708 / #21374)
Changes:
- hermes_state.apply_wal_with_fallback(): shared helper that tries WAL
and falls back to DELETE on SQLITE_PROTOCOL-style errors with one
WARNING explaining why
- hermes_state.get_last_init_error() + format_session_db_unavailable():
capture the init failure cause and surface it in user-facing strings
(with an NFS/SMB pointer for 'locking protocol')
- hermes_cli/kanban_db.connect(): use the shared helper
- gateway/run.py: bump SessionDB init failure log DEBUG -> WARNING
(matches cli.py's existing correct behavior)
- cli.py (4 sites) + gateway/run.py (5 sites): replace bare
'Session database not available.' with format_session_db_unavailable()
Tests: 12 new tests in tests/test_hermes_state_wal_fallback.py + 1 new
test in tests/hermes_cli/test_kanban_db.py. Existing suites (state,
kanban, gateway, cli) remain green for all tests unrelated to pre-existing
failures on main.
Evidence: real-world user on NFSv3 mount (172.26.224.200:d2dfac12/home,
local_lock=none) reporting 'Session database not available.' on /resume;
'locking protocol' appears in 4 distinct log entries across backup,
kanban, TUI, and CLI paths in the same session.
closes#22032
The kanban-worker skill (built into the gateway dispatcher's spawn
prompt) instructs every worker to hand off via
``kanban_complete(summary=..., metadata=...)``. That writes the summary
onto the closing ``task_runs`` row, NOT onto ``tasks.result`` — the
latter is left NULL unless the caller passes ``result=`` explicitly.
Result: a glance at the dashboard or ``hermes kanban show <id>`` shows
a blank "Result:" section even when the worker did real work, which
on 2026-05-05 caused a Mac false-alarm ("Hermes did nothing") on a
task that had a 10-line completion summary on its run.
This patch surfaces the latest non-null run summary as
``latest_summary`` so the worker's actual handoff lands in front of
operators.
* New helpers ``kanban_db.latest_summary(conn, task_id)`` and
``kanban_db.latest_summaries(conn, task_ids)``. The batch variant
uses a single window-function SELECT so the dashboard board endpoint
doesn't pay an N+1 cost on multi-hundred-task boards.
* CLI ``hermes kanban show <id>`` prints a "Latest summary:" block
when ``tasks.result`` is empty but a run has produced a summary
(the existing "Result:" section still wins when populated, so the
back-compat path for hand-edited results is untouched). JSON output
gains a top-level ``latest_summary`` field.
* Dashboard ``/board`` and ``/tasks/{id}`` now include a
``latest_summary`` field on every task. Cards on /board carry a
200-character preview (cheap to render, plenty for "what did this
worker do?" at a glance); the drawer/detail endpoint returns the
full summary.
* Five new tests cover: empty-runs case, post-complete surface,
newest-of-multiple selection, empty-string skip, batch with
missing tasks + empty input.
Smoke-tested locally against the live profile DB on the three
acceptance-criterion targets (t_f08fef91 cron-hygiene-audit,
t_007b7f1c EMA-analysis, t_05746fa4 self-assessment) — all three now
return their populated summaries via both ``latest_summary`` and
``latest_summaries``.
Test plan: 255/255 kanban tests pass + 91/91 dashboard plugin tests
pass. No regression on tasks where ``tasks.result`` is explicitly
populated (the existing "Result:" branch is preserved).

After PR #20105 (dispatcher skips ready tasks whose assignee fails
``profile_exists()`` to prevent the orion-cc/orion-research crash
loop), the gateway and CLI emit a spurious "kanban dispatcher stuck:
ready queue non-empty for N consecutive ticks but 0 workers spawned"
warning every 5 minutes on multi-lane setups where the queue is
steadily full of human-pulled work assigned to terminal lanes.
The warn is intended to catch real failure modes (broken PATH,
missing venv, credential loss for a real Hermes profile). On a
multi-lane host it fires forever even though everything is healthy:
the dispatcher correctly chose not to spawn, and there is nothing
for the operator to fix.
Changes:
* ``DispatchResult`` gains a ``skipped_nonspawnable`` field
(separate from ``skipped_unassigned``) so callers can distinguish
"task missing an owner — operator should route it" from "task
owned by a control-plane lane — terminal will pull it".
* ``dispatch_once`` routes the ``not profile_exists(assignee)`` skip
into the new bucket (was lumped into ``skipped_unassigned``).
* New helper ``has_spawnable_ready(conn)`` returns True iff at least
one ready+assigned+unclaimed task in the DB has an assignee that
maps to a real Hermes profile. Falls back to legacy "any
ready+assigned" when ``profile_exists`` is unimportable so degraded
installs still surface the original warn.
* The gateway dispatcher (``gateway/run.py``) and the CLI standalone
daemon (``hermes_cli/kanban.py``) both swap their cheap
``ready_nonempty`` probe to use ``has_spawnable_ready``. Stuck-warn
now fires only when there is genuine spawnable work the dispatcher
failed to start.
* CLI dispatch output prints ``Skipped (non-spawnable assignee —
terminal lane, OK)`` for visibility without alarm.
Tests:
* New ``has_spawnable_ready`` cases (empty queue, terminal-lane
only, mixed real+terminal).
* New ``test_dispatch_skips_nonspawnable_into_separate_bucket``
verifies the bucketing change.
* Updated ``test_dispatch_skips_unassigned`` to assert no
cross-leak.
* Added ``all_assignees_spawnable`` fixture in
``tests/hermes_cli/conftest.py`` and threaded it through dispatcher
tests that use synthetic assignees ("alice", "bob"). PR #20105
(the parent commit) silently broke 8 such tests by routing those
assignees into ``skipped_nonspawnable`` instead of spawning; this
PR repairs them as part of the same code area.
Verified locally: 246/246 kanban-suite tests pass.

- Add normalize_profile_name() for lowercase canonical IDs and Default alias
- Use canonical names in create/delete/rename/export/import/set_active paths
- Canonicalize Kanban assignee on create/assign, list filter, and worker spawn
- Tests for mixed-case assignees and profile resolution (fixes#18498)
Layers defense-in-depth on top of the shared-root anchoring (base commit).
Changes in hermes_cli/kanban_db.py:
- kanban_db_path() now honours HERMES_KANBAN_DB first, then falls through
to kanban_home()/kanban.db.
- workspaces_root() now honours HERMES_KANBAN_WORKSPACES_ROOT first, then
falls through to kanban_home()/kanban/workspaces.
- All three overrides (HERMES_KANBAN_HOME, HERMES_KANBAN_DB,
HERMES_KANBAN_WORKSPACES_ROOT) now call .expanduser() for consistency.
- _default_spawn() injects HERMES_KANBAN_DB and
HERMES_KANBAN_WORKSPACES_ROOT into the worker subprocess env. Even
when the worker's get_default_hermes_root() resolution somehow
disagrees with the dispatcher's (symlinks, unusual Docker layouts),
the two processes still open the same SQLite file.
Module docstring updated to describe all three overrides and the
dispatcher env-injection contract.
Tests (tests/hermes_cli/test_kanban_db.py, TestSharedBoardPaths):
- test_hermes_kanban_db_pin_beats_kanban_home
- test_hermes_kanban_workspaces_root_pin_beats_kanban_home
- test_empty_per_path_overrides_fall_through
- test_dispatcher_spawn_injects_kanban_db_and_workspaces_root
(monkeypatches subprocess.Popen, asserts both env vars reach the
child even after HERMES_HOME is rewritten by `hermes -p <profile>`.)
Docs: website/docs/reference/environment-variables.md gets entries
for the three kanban env vars.
This fusion is built on the cleanest of the seven competing PRs that
targeted issue #18442:
* Base commit (from PR #19350 by @GodsBoy): add `kanban_home()` helper
anchored at `get_default_hermes_root()`, reroute all 5 kanban path
sites through it (including the 3 sibling log-dir sites that the
other six PRs missed), 8-test regression class.
* Dispatcher env-var injection approach drawn from PRs #18300
(@quocanh261997) and #19100 (@cg2aigc).
* Per-path env overrides drawn from PR #19100 (@cg2aigc).
* get_default_hermes_root() resolution direction first proposed in
PR #18503 (@beibi9966) and PR #18985 (@Gosuj).
Closes the duplicate/competing PRs: #18300, #18503, #18670, #18985,
#19037, #19056, #19100. Fixes#18442 and #19348.

The Kanban board is documented as shared across all Hermes profiles, but
`kanban_db_path()` and `workspaces_root()` resolved through `get_hermes_home()`,
which returns the active profile's HERMES_HOME. When the dispatcher spawned a
worker with `hermes -p <profile> --skills kanban-worker chat -q "work kanban
task <id>"`, the worker rewrote HERMES_HOME to the profile subdirectory before
kanban_db.py imported, opening a profile-local `kanban.db` that did not contain
the dispatcher's task. `kanban_show` and `kanban_complete` failed; the
dispatcher's row stayed `running` and was retried/crashed. The same defect
applied to `_default_spawn`'s log directory and `worker_log_path`, so
`hermes kanban tail` did not see the worker's output.
Add `kanban_home()` in `hermes_cli/kanban_db.py` that resolves through
`HERMES_KANBAN_HOME` (explicit override) then `get_default_hermes_root()`,
which already understands the `<root>/profiles/<name>` and Docker / custom
HERMES_HOME shapes. Reroute `kanban_db_path`, `workspaces_root`, the
`_default_spawn` log directory, `gc_worker_logs`, and `worker_log_path`
through it. Profile-specific config, `.env`, memory, and sessions stay
isolated as before; only the kanban surface is shared.
Add a `TestSharedBoardPaths` regression class to `tests/hermes_cli/test_kanban_db.py`
covering: default install, profile-worker convergence, Docker custom HERMES_HOME,
Docker profile layout, explicit `HERMES_KANBAN_HOME` override, and a real
SQLite round-trip across dispatcher and worker HERMES_HOME perspectives.
The dispatcher/worker convergence tests fail on origin/main and pass after
the fix.
Update the `kanban.md` user-guide page and the misleading docstrings in
`kanban_db.py` to describe the shared-root behavior.
Fixes#19348
New `hermes kanban` CLI subcommand + `/kanban` slash command + skills for
worker and orchestrator profiles. SQLite-backed task board
(~/.hermes/kanban.db) shared across all profiles on the host. Zero
changes to run_agent.py, no new core tools, no tool-schema bloat.
Motivation: delegate_task is a function call — sync fork/join, anonymous
subagent, no resumability, no human-in-the-loop. Kanban is the durable
shape needed for research triage, scheduled ops, digital twins,
engineering pipelines, and fleet work. They coexist (workers may call
delegate_task internally).
What this adds
- hermes_cli/kanban_db.py — schema, CAS claim, dependency resolution,
dispatcher, workspace resolution, worker-context builder.
- hermes_cli/kanban.py — 15-verb CLI surface and shared run_slash()
entry point used by both CLI and gateway.
- skills/devops/kanban-worker — how a profile should work a claimed task.
- skills/devops/kanban-orchestrator — "you are a dispatcher, not a
worker" template with anti-temptation rules.
- /kanban slash command wired into cli.py and gateway/run.py. Bypasses
the running-agent guard (board writes don't touch agent state), so
/kanban unblock can free a stuck worker mid-conversation.
- Design spec at docs/hermes-kanban-v1-spec.pdf — comparative analysis
vs Cline Kanban, Paperclip, NanoClaw, Gemini Enterprise; 8 patterns;
4 user stories; implementation plan; concurrency correctness.
- Docs: website/docs/user-guide/features/kanban.md, CLI reference
updated, sidebar entry added.
Architecture highlights
- Three planes: control (user + gateway), state (board + dispatcher),
execution (pool of profile processes).
- Every worker is a full OS process, spawned as `hermes -p <profile>`.
No in-process subagent swarms — solves NanoClaw's SDK-lifecycle
failure class.
- Atomic claim via SQLite CAS in a BEGIN IMMEDIATE transaction; stale
claims reclaimed 15 min after their TTL expires.
- Tenant namespacing via one nullable column — one specialist fleet
can serve many businesses with data isolation by workspace path.
Tests: 60 targeted tests (schema, CAS atomicity, dependency resolution,
dispatcher, workspace kinds, tenancy, CLI + slash surface). All pass
hermetic via scripts/run_tests.sh.
