+# Repairing joint conference membership
+
+EURAI's [official history](https://www.eurai.org/ecai/history) identifies ECAI 2018
+and 2022 as joint IJCAI/ECAI conferences. The pinned DBLP volumes
+`conf/ijcai/2018` and `conf/ijcai/2022` use `IJCAI` as their booktitle and title.
+Existing records can therefore already be present under IJCAI while an ECAI query
+shows a missing year. Adding ECAI as a global alias to the ordinary IJCAI venue
+would incorrectly include all other IJCAI years.
+
+The existing canonical `ECAI+IJCAI` venue has both member aliases. This maintenance
+command changes only the venue reference of the two existing `main` edition rows.
+Edition IDs, submission IDs, decisions, source text, authors, identifiers, tags,
+source links and coverage records stay intact. It does not merge or create papers
+or submissions, resolve per-paper tracks, or turn reviews into negative decisions.
+The DBLP collector applies the joint mapping only to these two exact main volume
+keys; original booktitle/title remain in source metadata with the membership evidence.
+The shared ingestion entry point also resolves these exact pinned source volumes before
+creating an edition, so refreshing an older normalized file cannot recreate a separate
+IJCAI edition. Other sources, years, workshop volumes and additional tracks retain their existing rules.
+
+## Review a read-only plan
+
+Use a runtime containing this repair command. The configured PostgreSQL writer lock
+is used only for the apply operation; do not replace a newer ingestion runtime with
+an older main-based feature branch.
+
+```sh
+PGSERVICEFILE=/etc/paper-atlas/pg_service.conf paper-atlas maintain joint-editions \
+  --pg-service foundry-research --pg-schema research --out joint-plan.json
+```
+
+The preflight requires the existing joint venue and exactly its two member aliases,
+one nonempty unambiguous edition per year, and matching pinned DBLP volume evidence
+for every existing submission. A colliding target edition, missing provenance or
+unexpected source scope fails closed. The plan binds current database/schema, IDs,
+counts and full fingerprints of affected papers, identifiers, source records, tags,
+submissions, decisions and their provenance, and coverage rows. Observation time is
+recorded separately from conference year. These are scoped checks, not a final global
+identity or conference completeness audit.
+
+## Apply the exact reviewed plan
+
+Compute the file's SHA256 after review and pass it explicitly:
+
+```sh
+PGSERVICEFILE=/etc/paper-atlas/pg_service.conf paper-atlas maintain joint-editions \
+  --pg-service foundry-research --pg-schema research --plan joint-plan.json \
+  --plan-sha256 "$PLAN_SHA256" --out joint-applied.json
+```
+
+The plan hash is checked before opening a writer. Current evidence is checked again
+under the dataset writer lock; both edition updates and an audit marker commit in one
+transaction. Protected row hashes are checked again before commit. Changed evidence
+requires a fresh reviewed plan. Existing output reports are preserved; choose a new
+path for another run. SQLite samples use `--db sample.sqlite`; the frozen production
+backup remains protected.
+
+If a response is lost after commit, rerun with the same plan and a new output path.
+When protected evidence is unchanged and both editions already point to the joint
+venue, the result is `already_joint` with zero updates. It does not replay imports or
+regenerate source records. Keep the plan, apply report and independent postcheck
+alongside collection evidence. The audit marker is `joint_ijcai_ecai_2018_2022_v1`.
+
+Publication counts can differ between the DBLP volume and the current publisher
+page. This membership repair preserves all existing rows rather than deleting entries
+to force an aggregate match; section-level main/invited/other classification and
+publication completeness require separate per-paper evidence.
