 - Base game vs. expansion vs. new edition is the top failure mode — bias matching toward `ambiguous` over auto-match ("Wingspan Europe" must not match base Wingspan).
 - Editions/versions matter: Eric owns multiple editions of some games — each is a separate collection entry (keyed by `collid` on BGG). Never guess a version: no legible cues → `version_unknown` and a version-less collection entry.
 - Normalize titles (casefold, strip punctuation/articles, special chars like é/&/:) identically on both sides of a match; dedupe across photos but keep `source_photos` provenance.
+- **Human curation is durable**: `data/title_splits.json` (titles split into per-photo copies) and `data/title_edits.json` (corrected reads/cues) are replayed on every titles.json rebuild, and both extract's and resolve's dedupe honor them forever. Row-level split decisions also persist via the `dedupe_veto` column.
 - **RPGs are local-only citizens**: when the board-game search runs dry, resolve falls back to `type=rpgitem` (same geekdo API/token). Matched rpgitems enrich into the library but diff routes them to `local_only` — they must never reach `to_add.csv`/upload (their collection lives on RPGGeek, out of scope).
 - Detailed BGG API behavior (202 queueing, collection-endpoint quirks, endpoints): use the `bgg-api` skill. **If the spec's BGG behavior changes, update the `bgg-api` skill to match** — they must not drift.
