 ## Unit tests — phrase filter
 
-- [ ] `_has_rejection_or_ats_signal` — rejection phrase at char 1501 (boundary)
-- [ ] `_has_rejection_or_ats_signal` — right single quote `\u2019` in "don't forget"
-- [ ] `_has_rejection_or_ats_signal` — left single quote `\u2018` in "don't forget"
-- [ ] `_has_rejection_or_ats_signal` — ATS subject phrase only checked against subject, not body
-- [ ] `_has_rejection_or_ats_signal` — spam subject prefix `@` match
-- [ ] `_has_rejection_or_ats_signal` — `"UNFORTUNATELY"` (uppercase → lowercased correctly)
-- [ ] `_has_rejection_or_ats_signal` — phrase in body quoted thread (beyond 1500 chars) is not blocked

 ## Integration tests — TODO label scan
 
-- [ ] `_scan_todo_label` — `todo_label` empty string → returns 0
-- [ ] `_scan_todo_label` — `todo_label` missing from config → returns 0
-- [ ] `_scan_todo_label` — folder doesn't exist on IMAP server → returns 0, no crash

-- [ ] `_scan_todo_label` — email matches no company term → skipped
-- [ ] `_scan_todo_label` — duplicate message-ID → not re-inserted
-- [ ] `_scan_todo_label` — stage_signal set when classifier returns non-neutral
-- [ ] `_scan_todo_label` — body fallback (company only in body[:300]) → still matches
-- [ ] `_scan_todo_label` — email handled by `sync_job_emails` first not re-added by label scan

 ## Integration tests — unmatched leads
 
-- [ ] `_scan_unmatched_leads` — genuine lead inserted with synthetic URL `email://domain/hash`
-- [ ] `_scan_unmatched_leads` — same email not re-inserted on second sync run
-- [ ] `_scan_unmatched_leads` — duplicate synthetic URL skipped
-- [ ] `_scan_unmatched_leads` — `extract_lead_info` returns `(None, None)` → no insertion
-- [ ] `_scan_unmatched_leads` — rejection phrase in body → blocked before LLM
-- [ ] `_scan_unmatched_leads` — rejection phrase in quoted thread > 1500 chars → passes filter (acceptable)

 ## Integration tests — full sync
 
-- [ ] `sync_all` with no active jobs → returns dict with all 6 keys incl. `todo_attached: 0`
-- [ ] `sync_all` return dict shape identical on all code paths
-- [ ] `sync_all` with `job_ids` filter → only syncs those jobs
-- [ ] `sync_all` `dry_run=True` → no DB writes
-- [ ] `sync_all` `on_stage` callback fires: "connecting", "job N/M", "scanning todo label", "scanning leads"
-- [ ] `sync_all` IMAP connection error → caught, returned in `errors` list
-- [ ] `sync_all` per-job exception → other jobs still sync

 ## Config / UI
 
-- [ ] Settings UI field for `todo_label` (currently YAML-only)
-- [ ] Warn in sync summary when `todo_label` folder not found on server
-- [ ] Clear error message when `config/email.yaml` is missing
-- [ ] `test_email_classify.py --verbose` shows correct blocking phrase for each BLOCK

 ## Backlog — Known issues
 
-- [ ] **The Ladders emails confuse the classifier** — promotional/job alert emails from `@theladders.com` are matching the recruitment keyword filter and being treated as leads. Fix: add a sender-based skip rule in `_scan_unmatched_leads` for known job board senders (similar to how LinkedIn Alert emails are short-circuited before the LLM classifier). Senders to exclude: `@theladders.com`, and audit for others (Glassdoor alerts, Indeed digest, ZipRecruiter, etc.).

 ## Performance & edge cases
 
-- [ ] Email with 10 000-char body → truncated to 4000 chars, no crash
-- [ ] Email with binary attachment → `_parse_message` returns valid dict, no crash
-- [ ] Email with multiple `text/plain` MIME parts → first part taken
-- [ ] `get_all_message_ids` with 100 000 rows → completes in < 1s
