The source file (`C:\claudetools\.claude\tmp\treb-data\defaultwhat.csv`) was a 92-column Outlook export containing 664 contacts (4,397 physical lines due to multi-line Notes fields). The goal was to produce an importable CSV with duplicates merged so it would re-import into Outlook cleanly. + +Initial analysis found the data was cleaner than expected at the row level (0 cross-row shared emails), but the real duplication was *within* each contact: the three email slots (Email / Email 2 / Email 3) held the same address repeated as case-variants and trailing-dot variants (e.g. `tellerbie@afatucson105.org`, `Tellerbie@Afatucson105.Org`, `tellerbie@afatucson105.org.`). Outlook's Address Book renders one line per email address, so one contact appeared as 2-3 "duplicate" lines. A second corruption pattern was found later: truncated-domain variants (`email.arizona.edu` -> `email.edu`) and malformed `name(email)` forms. A Python script (`clean_contacts.py`) was built iteratively to normalize and dedupe email slots, condense triplicated Notes blocks (fuzzy-match, keep most complete copy), merge empty stub contacts, fix display names to show the person's name instead of the raw email, and apply curated same-person/household merges. + +Significant time was spent diagnosing why imports failed. First import produced only a few contacts (multi-line Notes broke the legacy line-based importer). Removing the UTF-8 BOM and switching to Windows ANSI (cp1252) encoding with flattened single-line records (Notes newlines -> ` | `) and minimal quoting finally matched the user's working template and imported successfully. A single-contact test file (`alan-test.csv`) confirmed the format. + +The latter half of the session was spent clarifying that the *remaining* duplicates the user saw in the Address Book were **import-accumulation artifacts** — Outlook adds a fresh copy on every import and never replaces, and the file had been imported 5+ times during troubleshooting. Different import versions handled Notes differently, so duplicate copies of the same contact had inconsistent notes (one with the note, one blank). The CSV itself was proven clean (0 shared names, 0 shared emails). The user had also been conflating two different people — **Alan Lafever** (gmail, no note) and **Alan Levene** (aol + gmail, with the Phoenix/Tucson household note). Both were verified correct in the clean file. Session ended with the user confirming everything was correct. + +Final output: `defaultwhat-clean.csv` — 627 deduped contacts (from 664), cp1252/no-BOM/single-line format ready for a clean wipe-and-import-once. + +## Key Decisions + +- **Within-contact email dedup over row dedup.** The actual duplication was redundant email slots inside single contacts, not duplicate rows. Normalized by lowercasing, stripping internal spaces and trailing dots; later extended to collapse truncated-domain variants (same local part + domain-label-subset) and extract emails from malformed `name(email)` strings. +- **Kept genuinely distinct multiple emails as real Email 2/Email 3 fields** (Option A), not collapsed to one. The user confirmed this matches Outlook's documented 3-email-per-contact behavior; the multi-line Address Book display is expected rendering, not duplication. +- **cp1252 + no BOM + flattened single-line Notes** for the output. The legacy line-based importer corrupted multi-line quoted Notes and the UTF-8 BOM mangled the first header (`Title`), causing a blank import. Matched the user's `Sample CSV file for importing contacts.csv` template byte-format. +- **Haney split into two people** (Tommy D. Haney with 3 addresses + Sandy Haney), cross-linked via the Spouse field and a shared condensed note — based on note content showing tdhmgtllc/tdhassoc are Tom's businesses and schaney@att.net is Sandy. +- **Conservative auto-merge with curated list.** Fuzzy name matching over-flagged people sharing first names (9 different "Linda"s, multiple "Ron"/"Chris"/"Kevin"). Auto-merged only high-confidence same-person/household pairs (17) via an explicit email-keyed `MERGE_GROUPS` list; left coincidental-first-name matches separate. +- **Deleted junk empty stubs** (FAQ, Owner, Undisclosed-Recipient:;, Linda, Brad, Brady) but kept name-only real-person stubs (Arlene Lombard, Vanna Randall, Brian/Sze Miller). + +## Problems Encountered + +- **Heredoc / `python3` failed on Windows (exit 49).** Switched to writing `clean_contacts.py` to disk and running with `python`. +- **First import: only a few contacts.** Cause: multi-line Notes broke the legacy line-based importer. Fix: flatten Notes newlines to ` | ` so each contact is one physical line. +- **Second import: blank address book.** Cause: UTF-8 BOM corrupted the first header so no fields mapped; cp1252 bytes were also invalid if read as UTF-8. Fix: write no-BOM cp1252, matching the template. +- **Persistent "duplicate" contacts after fixes.** Root cause was Outlook import-accumulation (5+ imports stacking copies across folders), not the CSV. Resolved by explaining the wipe-all-folders-then-import-once procedure; CSV proven dup-free. +- **User/Claude name confusion (Lafever vs Levene).** Two different Alans. The household note ("Linda cell / Alan cell") belongs to Alan Levene; Alan Lafever genuinely has no note. Notes on the duplicate Lafever copies were bleed-over from neighbor William Lafferty during a broken multiline parse. Both verified correct in the clean file. + +## Configuration Changes + +No repo configuration changed.
