Three follow-ups from review on #28296:
1. Sync worker outliving the bounded join. Each sync_turn POST has
_TIMEOUT=30s and there are two per turn, but on_session_end and
on_session_switch only join for 10s. If the worker is still alive
after the join, committing the old session orphans the worker's
late writes past the commit boundary — they land in an already-
committed session and never get extracted. Both hooks now re-check
is_alive() after the join and skip the commit when the worker
hasn't drained.
2. on_memory_write late session_id capture. Same shape as the
pre-fix sync_turn: f-string for the post path read self._session_id
inside the worker, so a switch between thread spawn and post call
landed the memory note in the new session. Snapshot sid at call
time, same pattern as sync_turn.
3. Stale prefetch repopulating the new session. The pre-switch
drain+clear only protects against workers that finish before the
join completes; one finishing after the clear would write its
result into the new generation's slot. Added a monotonic
_prefetch_generation; workers capture it at spawn and refuse to
write if it has advanced.
Tests: existing in-flight-sync test updated to drain (it tested the
join-before-commit happy path); four new tests cover hung-writer skip
on end + switch, on_memory_write sid capture, and prefetch generation
gating. 177/177 memory tests pass.
Two hardening fixes prompted by review on #28296:
1. sync_turn() now snapshots the target session id before spawning the
worker. The previous code read self._session_id inside the worker, so
a worker delayed past on_session_switch's bounded join could read the
rotated-in NEW id and write the OLD turn's messages into the wrong
session.
2. on_session_end() resets _turn_count to 0 after a successful commit,
making the old-session commit path idempotent with the new switch
hook. /new and compression call commit_memory_session() (which fires
on_session_end) immediately before on_session_switch; without this,
the old session would be committed twice. On commit failure we leave
_turn_count > 0 so on_session_switch retries.

OpenVikingMemoryProvider only overrides on_session_end and inherits the
base-class no-op for on_session_switch. When the agent rotates session_id
(via /new, /branch, /reset, /resume, or context compression), the
provider's cached _session_id stays at the value initialize() captured.
All subsequent sync_turn writes then land in the already-closed old
session, and on_session_end tries to commit it a second time — the new
session never accumulates messages and never triggers memory extraction.
The fix mirrors the pattern Hindsight uses (#17508):
1. Wait for any in-flight sync thread to drain under the OLD _session_id
before we mutate it, otherwise the commit below races the last
message write.
2. Commit the old session if it accumulated turns — same extraction
semantics as on_session_end. Skip if empty (nothing to extract).
3. Drain in-flight prefetch from the old session and clear its cached
result so the new session doesn't see stale recall.
4. Rotate _session_id to the new value and reset _turn_count.
Commit failures are swallowed (logged at WARN) so a flaky server can't
strand the provider on the old session forever — same posture as the
existing on_session_end commit.
Salvages #22981 by @SimbaKingjoe. Adds 'kanban.max_in_progress' config
that caps simultaneously running tasks. When the board already has N
running, dispatcher skips spawning so slow workers (local LLMs,
resource-constrained hosts) don't pile up and time out.
Threads through dispatch_once(max_in_progress=) and gateway dispatcher
config parsing with validation (warns on invalid/below-1 values).
Salvages the substantive part of #22295 by @steezkelly. Adds the
missing HERMES_KANBAN_HOME, HERMES_KANBAN_RUN_ID, HERMES_KANBAN_CLAIM_LOCK,
HERMES_KANBAN_DISPATCH_IN_GATEWAY entries to _HERMES_BEHAVIORAL_VARS so
ambient developer-shell pins on those vars don't bleed into pytest runs.
The frozenset extraction + standalone regression test from the original
PR were dropped to keep the change minimal — main already maintains the
list inline.
Salvages #26431 by @LeonSGP43. Dashboard plugin_api list_diagnostics
was using exact-match (severity == filter), so '--severity warning'
hid 'error' and 'critical' diagnostics. Adds severity_at_or_above()
helper to kanban_diagnostics and uses it in the dashboard endpoint
(CLI already used SEVERITY_ORDER comparison correctly).
Salvages #24050 by @kronexoi. The single-task PATCH already rejects
direct status='running' since it bypasses the dispatcher/claim invariant,
but the bulk-update endpoint still accepted it. Aligns bulk with single
by emitting an error result row for any 'running' entry.
Salvages #25579 by @wesleysimplicio. Stamps task_runs.metadata.worker_session_id
from HERMES_SESSION_ID on kanban_complete. Cherry-picked the substantive
commit (not the AUTHOR_MAP fixup tip) onto current main.
When a systemic failure (provider outage, auth expiry, OOM) crashes
multiple workers simultaneously, detect_crashed_workers increments
each task failure counter independently. The circuit breaker only
trips after N × failure_limit retries across the fleet.
Fingerprint crash errors by normalizing host-specific details (PIDs,
timestamps). When 3+ tasks crash with the same fingerprint in a
single detection cycle, immediately trip the circuit breaker
(failure_limit=1) instead of waiting for repeated failures.
Isolated crashes (unique fingerprints) retain their normal retry
budget. Protocol violations continue to trip immediately.
Includes regression tests for systemic and isolated crash paths.
When a task is manually unblocked (blocked → ready/todo), the
consecutive_failures counter and last_failure_error were left intact.
The next failure would immediately re-trip the circuit breaker because
the counter was still at or above the failure limit.
Reset both fields on unblock so the task gets a fresh retry budget.
Includes a regression test that verifies counters are zeroed.
recompute_ready only scanned 'todo' tasks for promotion, ignoring
'blocked' tasks entirely. When a task was blocked (e.g. by the circuit
breaker) and its parent dependencies later completed, the task stayed
stuck in 'blocked' forever unless manually unblocked.
Now recompute_ready also scans 'blocked' tasks. When all parents are
done/archived, the blocked task is promoted to 'ready' with failure
counters reset — equivalent to an automatic unblock.
Includes a regression test for the blocked-parent-done promotion path.
Archiving or deleting a board via remove_board() leaves the path's
"schema already initialized" entry in the module-level cache. A
concurrent connect(board=<slug>) call (e.g. the dashboard event-stream
poll loop) then:
1. resolves the same kanban.db path,
2. recreates the directory + an empty sqlite file because
connect() does mkdir(parents=True, exist_ok=True),
3. skips the CREATE TABLE pass because the cache entry says the
schema is already in place,
4. errors on the next read with `no such table: task_events`.
Drop the cache entry before mutating the filesystem so the fresh file
gets a proper schema init on next connect(). Applies to both
archive=True (rename) and archive=False (rmtree) branches.
Fixes#23833.

The fix in 061a1830 added an outer try/except in plugin_api._task_dict
so that a future failure mode in kanban_db.task_age (anything _safe_int
doesn't already absorb) cannot 500 the GET /board response. The
_safe_int / task_age corruption paths got regression coverage in
tests/hermes_cli/test_kanban_db.py, but the OUTER fallback contract
remained untested -- meaning a refactor that drops the try/except would
not be caught by CI.
Pin that contract from both consumers of _task_dict:
- GET /board returns 200 with the literal fallback age dict for the
affected card (other cards continue to render via the same path)
- GET /tasks/:id (drawer view) returns 200 with the same fallback,
so a single corrupt task can't block its own drawer
Both tests force task_age to raise RuntimeError rather than ValueError
on '%s', because ValueError is absorbed by _safe_int and never reaches
the outer try/except -- testing that path would only re-cover what
test_kanban_db.py already pins.
Manually verified the regression discipline:
git checkout 061a1830^ -- plugins/kanban/dashboard/plugin_api.py
pytest -k task_age_exception # both FAIL with 500
git checkout HEAD -- plugins/kanban/dashboard/plugin_api.py
pytest -k task_age_exception # both PASS
Tests (``tests/hermes_cli/test_auth_manual_paste.py``):
* 9 parametrised + scalar cases for ``_is_remote_session`` covering
the new Cloud Shell / Codespaces / Gitpod / Replit / StackBlitz
env vars (plus the existing SSH ones).
* 9 cases for ``_parse_pasted_callback`` covering every paste form
(full URL, https URL with extra params, bare ``?code=...``, bare
``code=...`` fragment, bare opaque value, error+description,
empty, whitespace-only, malformed URL).
* 3 cases for ``_prompt_manual_callback_paste`` (happy path, EOF,
Ctrl-C).
* 3 end-to-end ``_xai_oauth_loopback_login(manual_paste=True)``
cases: the HTTP server MUST NOT be started (asserted via a
callable that raises if invoked), wrong state still rejected
with ``xai_state_mismatch`` (no CSRF bypass), and empty paste
surfaces ``xai_code_missing``.
* SSH-hint mention test ensures the ``--manual-paste`` instruction
is printed in the remote-session hint.
Docs:
* ``oauth-over-ssh.md`` — new "Browser-only remote (Cloud Shell /
Codespaces / EC2 Instance Connect)" section with the
``--manual-paste`` recipe, plus a TL;DR note for the new flag.
* ``xai-grok-oauth.md`` — short subsection pointing at the same
recipe and the OAuth-over-SSH guide anchor.
Salvages #19964 by @Beandon13. Adds `hermes kanban archive --rm` to
permanently remove already-archived tasks with cascading cleanup of
links, comments, events, runs, and notify-subs. Safety guard: only
archived tasks can be deleted; active/blocked/done must be archived
first.
Cherry-picked from #19964 onto current main (severe stale base, applied
manually to preserve substance only).
Tests:
* ``test_refresh_xai_oauth_pure_403_marked_tier_denied_not_relogin`` —
refresh-403 raises ``xai_oauth_tier_denied`` with
``relogin_required=False`` and the API-key fallback hint in body.
* ``test_format_auth_error_tier_denied_does_not_suggest_relogin`` —
the renderer does not append "Run ``hermes model``" for the new
code.
* ``test_recover_with_credential_pool_skips_refresh_on_bare_403_for_xai_oauth`` —
bare ``{"reason":"forbidden","message":"Forbidden"}`` body (which
does not match the existing keyword heuristic) still short-circuits
``try_refresh_current`` on xai-oauth.
Docs:
* Drop the "(any active tier)" claim from the xai-grok-oauth guide,
add a top-of-page warning callout, and a Troubleshooting section
for the 403-after-login case pointing at ``XAI_API_KEY`` +
``provider: xai`` as the documented fallback.
Qwen3.x and DeepSeek-V3.x default to chatty/hallucinatory tool use without
enforcement steering — agents narrate "calling tool X" without actually
emitting a tool call, or run partial loops. Both model families fit the
same failure pattern TOOL_USE_ENFORCEMENT_GUIDANCE was already injected
for (gpt, codex, gemini, gemma, grok, glm).

Squashed salvage of:
- 403e567ce fix(agent): add qwen and deepseek to TOOL_USE_ENFORCEMENT_MODELS

Fixes#28079.
The conversation_loop.py references _pool_may_recover_from_rate_limit which
was defined in run_agent.py. After the conversation-loop extraction refactor,
the helper was no longer in the same module scope. Wrap the call as
_ra()._pool_may_recover_from_rate_limit() to route through the run_agent
monkeypatch namespace where the helper is available.
Adds regression test in test_gemini_fast_fallback.py.
Fixes: MAILROOM Email Triage NameError, OPS Execution Monitor NameError.
resolve_xai_oauth_runtime_credentials() called _refresh_xai_oauth_tokens()
with no try/except. A terminal refresh failure (HTTP 400/401/403 —
invalid_grant, token revoked) propagated without clearing the dead
access_token / refresh_token from auth.json, causing every subsequent
session to retry the same doomed network request.
Add a try/except around the refresh call that mirrors the existing
credential_pool.py quarantine: when _is_terminal_xai_oauth_refresh_error
identifies a non-retryable failure, clear the dead token fields from
auth.json and write a last_auth_error diagnostic marker so future calls
fail fast with a clear relogin_required error instead of hitting the
network.
active_provider is preserved (set_active=False) so multi-provider users
whose chosen provider is not xai-oauth are unaffected.
Tests: two new cases in test_auth_xai_oauth_provider.py cover terminal
quarantine and transient pass-through.
* feat: add /update slash command to CLI and TUI
* test(cli): add Python tests for /update slash command
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(cli): address Copilot review for /update slash command
Route classic CLI /update through prompt_toolkit modal confirmation and
defer relaunch to the main-thread cleanup path after app.exit(). Tighten
Y/n semantics, add Python wrapper and catalog coverage tests, and assert
/update stays visible in the TUI command catalog.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(cli): address review feedback on /update command
- Replace raw input() with _prompt_text_input_modal in _handle_update_command
to avoid EOF/hang/keystroke-leak races with prompt_toolkit's stdin ownership
- Fix confirmation logic: only proceed on recognized affirmative aliases
(y/yes/1/ok); cancel on everything else including empty string, typos,
and unrecognized input — matches all other [Y/n] prompts in the codebase
- Route relaunch through main-thread shutdown path: set _pending_relaunch
and return False from process_command so process_loop triggers app.exit();
run() then calls relaunch() after prompt_toolkit has restored terminal modes
and after cleanup — safe on both POSIX (execvp) and Windows (subprocess+exit)
- Fix misleading docstring in test_update_command.py: the Vitest only covers
the TypeScript slash handler that emits code 42, not the Python wrapper
branch that acts on it
- Rewrite tests to use SimpleNamespace pattern (like test_destructive_slash_confirm)
so _prompt_text_input_modal can be stubbed directly
- Add Python test for _launch_tui exit-code-42 → relaunch branch in main.py

Extends #26573 to also catch the case the original PR deliberately left
out: when a tool raises an exception, the agent's tool executor wraps it
in a canonical 'Error executing tool '<name>': ...' string prefix (see
agent/tool_executor.py around the try/except). That prefix is unique to
the wrapper and cannot legitimately appear in well-behaved tool output,
so it is a safe signal that the tool blew up.
Without this, the canonical 'tool raised' case still rendered as a green
'completed' row in Zed despite being a runtime failure — exactly the
class of bug #26573 set out to fix.
Adds a positive test (raised-exception prefix -> failed) and a negative
test (bare 'Error:' word in legit tool output stays completed) so a
future contributor doesn't accidentally widen the rule to false-positive
on compiler/linter diagnostics.
