📝 WalkthroughWalkthroughThis PR removes the APScheduler dependency, refactors type safety by introducing a Tier enum to replace string tier values, converts the ProbeState.discovered property to a get_all_discovered() method, and adds exponential backoff retry logic to the probe mechanism.

518-519: 💤 Low valueConsider logging malformed Last-Modified headers.
The static analyzer flags the
try-except-passpattern (S110). While verbose logging of every malformed header may not be desired, a debug-level log could help diagnose issues with specific servers.♻️ Optional: Add debug logging
try: last_modified = parsedate_to_datetime(lm_str) threshold = timedelta(hours=self.cfg.alert_modified_hours) is_recent = ( datetime.now(timezone.utc) - last_modified ) <= threshold - except Exception: - pass + except Exception as exc: + log.debug("Failed to parse Last-Modified '%s' for %s: %s", lm_str, url, exc)🤖 Prompt for AI Agents
Verify each finding against current code. Fix only still-valid issues, skip the rest with a brief reason, keep changes minimal, and validate. In `@src/paperscout/sources.py` around lines 518 - 519, The silent except block swallowing errors when parsing Last-Modified headers should be replaced with a debug-level log so malformed headers can be diagnosed; locate the try/except around Last-Modified parsing (the except Exception: pass) in src/paperscout/sources.py and change it to log the header value and error (e.g., logger.debug with the header content and exception info or use exc_info=True) instead of passing, keeping behavior non-failure but recording details for troubleshooting.
487-553: 💤 Low valueUnreachable code after retry loop.
The
elseclause on line 499-500 andreturn Noneon line 553 are unreachable. The for-loop either exits viabreak(line 491) orreturn None(line 498), so theelseblock never executes. Similarly, line 553 is outside theasync with sem:block but can never be reached.♻️ Proposed cleanup
async with sem: _max_retries = 3 for _attempt in range(_max_retries): try: resp = await client.head(url) break except httpx.HTTPError as exc: if _attempt < _max_retries - 1: await asyncio.sleep(0.5 * (2 ** _attempt)) continue log.debug("ERR %s %s (after %d attempts)", url, exc, _max_retries) self._stats["error"] += 1 return None - else: - return None if resp.status_code != 200: # ... rest of the logic ... return ProbeHit(...) - return None🤖 Prompt for AI Agents

416-418: 💤 Low valueRedundant local import.
datetimeandtimezoneare already imported at the top of the file (line 7). The local import with aliases_dtand_tzis unnecessary.♻️ Remove redundant import
def _handle_status(state: ProbeState, paper_count_fn, say, reply_opts: dict) -> None: - from datetime import datetime as _dt, timezone as _tz last = state.last_poll - last_str = _dt.fromtimestamp(last, tz=_tz.utc).strftime("%Y-%m-%d %H:%M:%S UTC") if last else "never" + last_str = datetime.fromtimestamp(last, tz=timezone.utc).strftime("%Y-%m-%d %H:%M:%S UTC") if last else "never"🤖 Prompt for AI Agents

Ensure you keep the same conditional ("if last else 'never'") and the same strftime format while referencing datetime and timezone (not _dt/_tz) so the duplicate import and aliased names are eliminated.

In `@src/paperscout/scout.py`:
- Around line 416-418: Remove the redundant local import "from datetime import
datetime as _dt, timezone as _tz" and change the usage to the module-level
imports already present at the top of the file; specifically update the
expression that builds last_str (which reads state.last_poll into last and
formats it) to call datetime.fromtimestamp(last, tz=timezone.utc). Ensure you
keep the same conditional ("if last else 'never'") and the same strftime format
while referencing datetime and timezone (not _dt/_tz) so the duplicate import
and aliased names are eliminated.
In `@src/paperscout/sources.py`:
- Around line 518-519: The silent except block swallowing errors when parsing
Last-Modified headers should be replaced with a debug-level log so malformed
headers can be diagnosed; locate the try/except around Last-Modified parsing
(the except Exception: pass) in src/paperscout/sources.py and change it to log
the header value and error (e.g., logger.debug with the header content and
exception info or use exc_info=True) instead of passing, keeping behavior
non-failure but recording details for troubleshooting.
- Around line 487-553: The for-loop's else and the trailing return None are
unreachable; remove the for ... else block and the final return None, and
instead after the retry loop (after the for _attempt in range(_max_retries): ...
break/except) add a simple presence check for resp (e.g. if resp is None or
"resp" not in locals(): return None) so the subsequent code that inspects
resp.status_code, parses last-modified and eventually returns ProbeHit (and
calls _fetch_front_text) only runs when resp is valid; reference symbols:
_max_retries, resp, for _attempt, ProbeHit, _fetch_front_text.
