compute_next_run parsed scheduled_time as "HH:MM" with int(parts[0]),
int(parts[1]) and no validation, so "9", "9am", "25:00", "9:" or ":30" raised
IndexError/ValueError. The POST /tasks create route passes the user/LLM-supplied
scheduled_time before its try block (and only validates the cron field), so a
bad value surfaced as an unhandled 500 rather than the clean 400 used for other
invalid fields — and the same crash could fire inside the scheduler loop when
recomputing next_run for an already-stored bad row.
Guard the parse and fail closed (warn + return None), matching the existing
invalid-cron handling in the same function.
Adds tests/test_scheduler_scheduled_time_validation.py — malformed values return
None (fail before with IndexError/ValueError), valid HH:MM still computes.
When a timezone is configured, `now` is tz-aware local time.
The comparison stripped tzinfo with `.replace(tzinfo=None)`,
producing naive local time, but `scheduled_date` is stored as
naive UTC. For users east of UTC this causes tasks to appear
expired prematurely; for users west they linger past due time.
Use `_to_utc_naive(now)` to convert to the same reference frame.
TaskScheduler.start() aborts stale TaskRun rows but never advanced
ScheduledTask.next_run. Across a restart the in-process _executing set
is empty, so the first post-restart _check_due_tasks() call dispatches
every task whose next_run is still in the past — and so does every
subsequent poll, until the task's regular _execute_task path finally
runs compute_next_run and pushes it forward.
start() now queries active tasks with next_run < now and pushes each
one to now + 60s. The first poll after restart sees them as not-yet-due,
the task runs once normally, and compute_next_run puts the schedule
back on its real cadence. Paused and not-yet-due tasks are left alone.
The validator test was rewritten as a regression test asserting the
opposite of the bug it originally demonstrated, plus two narrower cases
to lock down the filter (only active+overdue is touched).
* fix: coerce null endpoint_url when delivering task result to a session
* fix: also coerce null model so the session insert satisfies NOT NULL
* test: cover task session delivery on an empty database
* feat(web-fetch): add web_fetch tool to read a specific URL's content
* test(web-fetch): add SSRF coverage and fail closed on empty DNS resolution
Add explicit SSRF regression tests for the web_fetch path covering
loopback, private LAN ranges, link-local/metadata, IPv6 private/local,
redirect-into-private, and unsupported schemes. Harden _public_http_url
to fail closed when a hostname resolves to no addresses.
