requests library not available for webhook delivery

Error message

requests library not available for webhook delivery

What it means

Raised in _send_slack_webhook (and _send_generic_webhook) when the module-level `requests` symbol is None. watchlist.py imports requests in a try/except ImportError block, setting requests=None on failure; the webhook senders gate on `if not requests` and refuse to deliver because there is no HTTP client to POST with.

Solutions

1. Install requests in the environment: pip install requests (or add it to the project requirements).
2. If you cannot install requests, disable webhook delivery (clear the delivery_channel setting) so watchlist skips the send path entirely.
3. Note the outer _deliver_findings already wraps the call in try/except and prints to stderr, so a missing requests will not crash the research run, only the notification.

Example fix

# before (requests missing)
# delivery fails: 'requests library not available for webhook delivery'

# after
pip install requests
# or, in watchlist config, leave delivery_channel empty to skip delivery

def can_deliver_webhook():
    import importlib.util
    return importlib.util.find_spec("requests") is not None

# before scheduling delivery:
if not can_deliver_webhook():
    print("requests not installed; webhook delivery disabled", file=sys.stderr)

When it happens

Trigger: Running watchlist delivery while the `requests` package is not installed in the active Python environment. The pipeline's own http module may use urllib, but watchlist delivery specifically requires the third-party requests library.

Common situations: Slim container/venv that installed only the pipeline deps but not requests. Running watchlist.py under a different interpreter than the one that pip-installed dependencies. requests removed during a dependency cleanup.
