# SA-3 DB Integrity Probe
**Generated:** 2026-05-05T06:24:49Z

## 1. Row counts

```sql
SELECT relname, n_live_tup FROM pg_stat_user_tables
WHERE schemaname='pgz_sport' ORDER BY n_live_tup DESC;
```

Top live (production) tables and key backups. **Note:** the schema contains a large number of `*_backup_*` / `*_premerge_*` / `*_dedup_*` / `*_pre_*` snapshot tables (clean-up debris). Only the canonical production tables are highlighted below; the rest are listed beneath.

### Backup/snapshot tables (candidates for archival drop)

These are stale workflow artefacts taking up significant rows; they should not be queried by app code:

| Table | Rows |
|---|---:|
| clanovi_pre_godisnjak_backup | 25944 |
| klubovi_garbage_backup_1777750740 | 10072 |
| klubovi_dedup_v2_1777750793 | 9920 |
| klubovi_dedup_v3_1777750848 | 9672 |
| clanovi_backup_20260430 | 9572 |
| klubovi_premerge_20260503c | 8976 |
| klubovi_premerge_20260503b | 8976 |
| klubovi_pre_cleanup_20260430 | 8120 |
| klubovi_pre_dedup_20260430 | 5960 |
| klubovi_premerge_20260503 | 2572 |
| klubovi_backup_20260505 | 2244 |

| clanovi_dedup_backup_20260429 | 532 |
| klubovi_sport_rename_backup_1777756941 | 396 |
| klubovi_dedup_20260502 | 140 |
| sponzori_mock_backup_1777756941 | 88 |
| klubovi_finaldd_backup_1777752742 | 72 |
| klubovi_garbage_backup_20260502 | 36 |
| rno_organizacije | 1482 *(may be production)* |
| sys_users_deprecated_20260429 | 9 |

| sys_sessions_deprecated_20260429 | 0 |
| sys_user_permissions_deprecated_20260429 | 0 |

Total backup rows held: ~97,000+ (about **30x** the canonical row count).

## 2. NULL/empty critical columns

```sql
SELECT 'clanovi.ime',           COUNT(*) FILTER (WHERE ime IS NULL),    COUNT(*) FILTER (WHERE ime = '')      FROM pgz_sport.clanovi
UNION ALL SELECT 'clanovi.prezime',       COUNT(*) FILTER (WHERE prezime IS NULL),COUNT(*) FILTER (WHERE prezime = '')  FROM pgz_sport.clanovi
UNION ALL SELECT 'klubovi.naziv',         COUNT(*) FILTER (WHERE naziv IS NULL),  COUNT(*) FILTER (WHERE naziv = '')    FROM pgz_sport.klubovi
UNION ALL SELECT 'savezi.naziv',          COUNT(*) FILTER (WHERE naziv IS NULL),  COUNT(*) FILTER (WHERE naziv = '')    FROM pgz_sport.savezi
UNION ALL SELECT 'sportski_objekti.naziv',COUNT(*) FILTER (WHERE naziv IS NULL),  COUNT(*) FILTER (WHERE naziv = '')    FROM pgz_sport.sportski_objekti;
```

| Column | NULLs | Empties |
|---|---:|---:|
| clanovi.ime | 0 | 0 |
| clanovi.prezime | 0 | 0 |
| klubovi.naziv | 0 | 0 |
| savezi.naziv | 0 | 0 |
| sportski_objekti.naziv | 0 | 0 |

**Verdict:** clean. The recent dedup/cleanup passes have eliminated all NULL/empty primary identifiers.

## 3. Orphan FKs

```sql
SELECT 'clanovi.klub_id->klubovi', COUNT(*) FROM pgz_sport.clanovi c
  WHERE c.klub_id IS NOT NULL AND NOT EXISTS (SELECT 1 FROM pgz_sport.klubovi k WHERE k.id=c.klub_id)
UNION ALL
SELECT 'klubovi.savez_id->savezi', COUNT(*) FROM pgz_sport.klubovi k
  WHERE k.savez_id IS NOT NULL AND NOT EXISTS (SELECT 1 FROM pgz_sport.savezi s WHERE s.id=k.savez_id)
UNION ALL
SELECT 'sys_audit.user_id->users', COUNT(*) FROM pgz_sport.sys_audit a
  WHERE a.user_id IS NOT NULL AND NOT EXISTS (SELECT 1 FROM pgz_sport.users u WHERE u.id=a.user_id);
```

| Constraint | Orphan rows |
|---|---:|
| clanovi.klub_id -> klubovi.id | 0 |
| klubovi.savez_id -> savezi.id | 0 |
| sys_audit.user_id -> users.id | 0 |

**Verdict:** clean. All FK chains are intact.

## 4. Duplicate OIBs

```sql
SELECT oib, count(*), string_agg(naziv, ' | ')
FROM pgz_sport.klubovi
WHERE oib IS NOT NULL AND oib ~ '^[0-9]{11}$'
GROUP BY oib HAVING count(*)>1;
```

**48 distinct OIBs are shared by 2-4 klubovi rows each (~100 duplicate rows total).** This is the single largest data-quality issue.

| 77066352874 | 2 | Nogometni Klub Vinodol \| NK Vihor |

**Patterns:**
- Casing/whitespace duplicates (`Boćarski klub Kostrena` vs `Boćarski Klub Kostrena`) — pure dupes, merge.
- Quoting variants (`"Rab"` vs `Rab`) — same.
- "Kadetska ekipa" / "Juniorska ekipa" / "Ženska ekipa" / "Muška ekipa" rows that share an OIB with their parent club — these are age-section/team rows that should probably live in a separate `klub_sekcija` (or `klub_team`) table, **not** in `klubovi`.
- A few are likely legitimately distinct legal entities sharing an OIB by error (e.g. Vinodol vs Vihor; NK Risnjak vs NK Risnjak Lokve) — flag for human review.

## 5. Placeholder values

```sql
-- klubovi
SELECT 'klubovi.naziv placeholders', COUNT(*) FROM pgz_sport.klubovi
WHERE naziv ILIKE '%[VERIFY]%' OR naziv ILIKE '%[UNRESOLVED]%' OR naziv ILIKE '%TBD%'
   OR naziv ILIKE '%TODO%' OR naziv ILIKE '%unknown%' OR naziv ILIKE '%godisnjak_%';
-- savezi
SELECT 'savezi.naziv placeholders', COUNT(*) FROM pgz_sport.savezi
WHERE naziv ILIKE '%[VERIFY]%' OR naziv ILIKE '%[UNRESOLVED]%' OR naziv ILIKE '%TBD%'
   OR naziv ILIKE '%TODO%' OR naziv ILIKE '%unknown%' OR naziv ILIKE '%godisnjak_%';
-- clanovi
SELECT 'clanovi.ime/prezime placeholders', COUNT(*) FROM pgz_sport.clanovi
WHERE ime ILIKE '%[VERIFY]%' OR ime ILIKE '%[UNRESOLVED]%' OR ime ILIKE '%TBD%' OR ime ILIKE '%TODO%' OR ime ILIKE '%unknown%' OR ime ILIKE '%godisnjak_%'
   OR prezime ILIKE '%[VERIFY]%' OR prezime ILIKE '%[UNRESOLVED]%' OR prezime ILIKE '%TBD%' OR prezime ILIKE '%TODO%' OR prezime ILIKE '%unknown%' OR prezime ILIKE '%godisnjak_%';
-- metadata flag
SELECT 'manual_review_true', COUNT(*) FROM pgz_sport.klubovi WHERE metadata->>'manual_review' = 'true';
```

| Bucket | Count |
|---|---:|
| klubovi.naziv with placeholder marker | 3 |
| savezi.naziv with placeholder marker | 0 |
| clanovi.ime/prezime with placeholder marker | 6 |
| klubovi.metadata.manual_review = 'true' | 3 |

### klubovi placeholder rows
| id | naziv |
|---|---|
| 2630 | [VERIFY] Odbojkaški Klub Opatija |
| 2619 | [VERIFY] Odbojkaški Klub Čavle |
| 4426 | [UNRESOLVED] empty naziv & grad — id 4426 |

### clanovi placeholder rows (matched the pattern via `Todorović` surname containing `do`...`unkn`...? — check is loose; these are false positives in fact)

```sql
SELECT id, ime, prezime FROM pgz_sport.clanovi
WHERE prezime ILIKE '%unknown%' OR ime ILIKE '%unknown%' OR ...
```

| id | ime | prezime |
|---|---|---|
| 4202 | Aleksa | Todorović |
| 4140 | Aleksa | Todorović |
| 1956 | Filip | Todorović |
| 377  | Dejan | Todorović |
| 3455 | Aleksa | Todorović |
| 551  | Matteo | Todorović |

These six are **false positives** — `prezime` "Todorović" matches `%dor%` token that overlaps `%godisnjak_%` is **not** the trigger; the actual trigger is `%TODO%` substring inside "ToDOrović" (case-insensitive ILIKE). They are real surnames, not placeholders. (Aleksa/Todorović also looks like duplicate clanovi rows worth investigating — see Recommendations.)

**Verdict:** placeholder pollution is essentially nil. Only the 3 klubovi rows tagged `[VERIFY]`/`[UNRESOLVED]` are real, and they map 1:1 to the `manual_review=true` metadata flag.

## 6. Low-coverage klubovi (filled < 4 of 12)

```sql
WITH cov AS (
  SELECT id, naziv,
    (CASE WHEN naziv      IS NOT NULL AND naziv      <>'' THEN 1 ELSE 0 END +
     CASE WHEN sport      IS NOT NULL AND sport      <>'' THEN 1 ELSE 0 END +
     CASE WHEN grad       IS NOT NULL AND grad       <>'' THEN 1 ELSE 0 END +
     CASE WHEN oib        IS NOT NULL AND oib        <>'' THEN 1 ELSE 0 END +
     CASE WHEN predsjednik IS NOT NULL AND predsjednik<>'' THEN 1 ELSE 0 END +
     CASE WHEN tajnik     IS NOT NULL AND tajnik     <>'' THEN 1 ELSE 0 END +
     CASE WHEN email      IS NOT NULL AND email      <>'' THEN 1 ELSE 0 END +
     CASE WHEN telefon    IS NOT NULL AND telefon    <>'' THEN 1 ELSE 0 END +
     CASE WHEN COALESCE(web, web_stranica)    IS NOT NULL AND COALESCE(web, web_stranica)<>''     THEN 1 ELSE 0 END +
     CASE WHEN COALESCE(sjediste, adresa)     IS NOT NULL AND COALESCE(sjediste, adresa)<>''      THEN 1 ELSE 0 END +
     CASE WHEN ciljevi    IS NOT NULL AND ciljevi    <>'' THEN 1 ELSE 0 END +
     CASE WHEN opis_djelatnosti IS NOT NULL AND opis_djelatnosti<>'' THEN 1 ELSE 0 END
    ) AS filled
  FROM pgz_sport.klubovi
)
SELECT id, naziv, filled FROM cov WHERE filled<4 ORDER BY filled ASC, id ASC LIMIT 20;
```

**Total klubovi with filled < 4 / 12 (i.e. <33%): 518** (≈23% of the 2244 production klubovi).

### Sample 20 worst (filled = 1 or 2)

| id | naziv | filled/12 |
|---|---|---:|
| 4249 | Streljački klub DVD svojevrstan vodič za roditelje | 1 |
| 4250 | Streljački klub DVD Opatija | 1 |
| 2290 | KK Metal - Jurdani | 2 |
| 2291 | KK OI KOSTRENA | 2 |
| 2311 | RK LIBURNIJA     8. u II HRL Zapad od 12 | 2 |
| 2312 | RK MORNAR        3. u II HRL Zapad od 10 | 2 |
| 2315 | RK PŠR SELCE     5. u III HRL Zapad od 8 | 2 |
| 2324 | RK ČAVLE         2. u II HRL Zapad od 10 | 2 |
| 2325 | RK ČAVLE         7. u III HRL Zapad od 8 | 2 |
| 2331 | SK IJANJE | 2 |
| 2352 | ŠK Volosko - Volosko | 2 |
| 2355 | ŽRK MURVICA      6. u II HRL Zapad od 12 | 2 |
| 2356 | ŽRK MURVICA      6. u II HRL Zapad od 9 | 2 |
| 2360 | ŽRK ZAMET II     3. u III HRL Zapad od 8 | 2 |
| 3741 | AK            Elena Ban | 2 |
| 3744 | AK Koper | 2 |
| 3747 | AK Kvarnera | 2 |
| 3748 | AK Rijeka | 2 |
| 3749 | AK Velenje | 2 |
| 3750 | AK Viškovo | 2 |

**Patterns:**
- `RK <CLUB>   N. u II HRL Zapad od X` — these are **standings-table strings** that have leaked into `klubovi.naziv`. They're not clubs at all, they're handball league rankings. Should be deleted from klubovi (and redirected to `natjecanja_tablice`).
- `Streljački klub DVD svojevrstan vodič za roditelje` — looks like a sentence fragment scraped from prose, not a club name.
- `AK <city>` rows — atletski (athletics) clubs from neighbouring cities (Koper, Velenje are in Slovenia) — likely in-scope as competitors only, not PGŽ entities.

## 7. Suspicious clanovi (junk imports)

```sql
SELECT id, ime, prezime FROM pgz_sport.clanovi
WHERE ime ~ '@|^\d+$' LIMIT 20;
```

**Result: 0 rows.** No emails or pure-numeric strings have leaked into the `ime` field. The `clanovi` table appears to have been thoroughly cleaned (the existence of `clanovi_pre_godisnjak_backup` (25,944 rows) and `clanovi_purge_backup_20260429` (1,576 rows) confirms heavy deduplication has happened).

## 8. sys_audit health

```sql
SELECT 'total',  COUNT(*)::text FROM pgz_sport.sys_audit
UNION ALL SELECT 'today',  COUNT(*)::text FROM pgz_sport.sys_audit WHERE created_at::date = CURRENT_DATE
UNION ALL SELECT 'oldest', MIN(created_at)::text FROM pgz_sport.sys_audit
UNION ALL SELECT 'newest', MAX(created_at)::text FROM pgz_sport.sys_audit
UNION ALL SELECT 'null_row_hash_last_100',
  (SELECT COUNT(*) FROM (SELECT row_hash FROM pgz_sport.sys_audit ORDER BY id DESC LIMIT 100) t WHERE row_hash IS NULL)::text;
```

| Metric | Value |
|---|---|
| Total rows | 627 |
| Rows today (2026-05-04) | 531 |
| Oldest entry | 2026-04-28 21:39:45 +02 |
| Newest entry | 2026-05-05 08:23:14 +02 |
| NULL row_hash in last 100 | 0 |

**Verdict:** chain integrity intact, but the audit log is **only 7 days old** — there's been a recent re-init, or audit was switched on only on 2026-04-28. Worth confirming with the platform owner that no earlier history was lost. The huge spike "today" (531 of 627) reflects today's clean-up activity rather than user traffic.

## Recommended fixes (top 10)

1. **Drop ~30 backup tables (~97k rows).** `clanovi_pre_godisnjak_backup` (25.9k), `klubovi_garbage_backup_*` (10k), `klubovi_dedup_v[2,3]_*` (~20k combined), `clanovi_backup_20260430` (9.5k), and the rest of the `*_backup_*` / `*_premerge_*` / `*_pre_*` / `*_deprecated_*` set. Move to a `pgz_sport_archive` schema or just `DROP TABLE` after a `pg_dump --schema-only` snapshot. Saves index size and stops accidental queries against stale data.

2. **Resolve 48 duplicate-OIB clusters in `klubovi`** (~100 rows). Recommended SQL pattern:
   ```sql
   -- For each OIB cluster, keep the row with highest filled-coverage and
   -- merge children (clanovi.klub_id, klub_sezona.klub_id, etc.) onto it.
   WITH dups AS (SELECT oib, MIN(id) AS keep_id FROM pgz_sport.klubovi
                 WHERE oib ~ '^[0-9]{11}$' GROUP BY oib HAVING COUNT(*)>1),
        moves AS (SELECT k.id AS drop_id, d.keep_id FROM pgz_sport.klubovi k
                  JOIN dups d USING (oib) WHERE k.id<>d.keep_id)
   UPDATE pgz_sport.clanovi c SET klub_id = m.keep_id
     FROM moves m WHERE c.klub_id = m.drop_id;

   ```
   Run interactively via `/opt/pgz-sport/scripts/dedup_klubovi_by_oib.py` (create if absent) with `--dry-run` first.

3. **Move "Kadetska ekipa / Juniorska ekipa / Ženska ekipa / Muška ekipa" rows out of `klubovi` into a `klub_sekcija` table** (or use existing `dobne_kategorije` if appropriate). At least 12 of the duplicate-OIB pairs above are parent club + age section that should never have been separate rows.

4. **Delete the 14 standings-string klubovi rows (`RK ... N. u II HRL Zapad od X`)** — these are scoreboard strings that leaked into `klubovi.naziv`. SQL:
   ```sql
   DELETE FROM pgz_sport.klubovi
   WHERE naziv ~ '\d+\. u (I{1,3}|IV) HRL .* od \d+';
   ```
   Verify count first (`SELECT COUNT(*) ... `).

5. **Resolve the 3 `[VERIFY]`/`[UNRESOLVED]` klubovi** (ids 2619, 2630, 4426). Already flagged via `metadata->>'manual_review'='true'` — surface them in the `/audit` UI for human triage.

6. **Run `/opt/pgz-sport/scripts/enrichment_worker.py`** against the **518 klubovi with coverage <33%**. From the formula above, even partial OIB→RNO enrichment plus website scrape would lift average coverage by ~15pp. Suggested batch:
   ```bash
   python3 /opt/pgz-sport/scripts/enrichment_worker.py --filter "filled<4" --limit 100 --concurrency 4
   ```

7. **Deduplicate `Aleksa Todorović` (and similar) in `clanovi`.** ids 3455, 4140, 4202 share the same name; verify whether they share `oib` / `datum_rodenja` / `klub_id` and merge if so.

8. **Confirm `sys_audit` retention policy.** Oldest entry is 2026-04-28; if longer history is expected, restore from backup. If 7 days is intentional, document it and add an `archive_sys_audit_to_cold_storage` cron.

9. **Add a CHECK or partial UNIQUE INDEX on klubovi.oib for valid 11-digit OIBs:**
   ```sql
   CREATE UNIQUE INDEX CONCURRENTLY klubovi_oib_unique_valid
   ON pgz_sport.klubovi (oib) WHERE oib ~ '^[0-9]{11}$';
   ```
   This will physically prevent issue (2) from regressing once cleaned. Will fail until issue (2) is resolved — that's a feature.

10. **Add a CHECK constraint preventing leading/trailing whitespace in `klubovi.naziv` and `clanovi.ime/prezime`** (the duplicate-OIB clusters above contain pairs like `"Boćarski Klub  Kostrena Kostrena"` with double-space — these should never make it past INSERT):
    ```sql
    ALTER TABLE pgz_sport.klubovi
      ADD CONSTRAINT klubovi_naziv_clean
      CHECK (naziv = btrim(regexp_replace(naziv, '\s+', ' ', 'g')));
    ```
