CC1: 3-subagent deep audit — Frontend / API gap / DB integrity

Reports in _audit/:
  audit_FRONTEND_COVERAGE.md  — SA-1 (Explore): 9 HTML files, 0 orphan handlers (clean)
  audit_API_GAP.md            — SA-2 (Explore): 356 backend routes vs 54 frontend paths
                                                23 missing routes / 39 call sites
  audit_DB_INTEGRITY.md       — SA-3 (general-purpose): 8 SQL probes, FKs/NULLs clean,
                                                        48 dup-OIB clusters, 518 low-cov klubovi
  audit_CONSOLIDATED.md       — top 10 critical with owner matrix (cc1/cc4/cc5/cc6)

Headlines:
  Frontend: clean (post-R3 refactors landed)
  API gap:  CRM module systemic — 16 of 23 missing routes need /crm prefix in crm.html
            6 missing routes are trailing-slash bugs in crm.html
  DB:       48 OIB dup clusters in klubovi (~100 rows) need merge+unique-index
            518/2244 klubovi (23%) <33% coverage → enrichment_worker target list
            14 scoreboard-string klubovi rows (RK ... HRL Zapad od X) → DELETE
            ~30 backup tables (~97k rows) cluttering pgz_sport schema

Owner allocation:
  cc1 → #6 backup-table archival, #8 verify, #9 sportas trailing-slash
  cc4 → #1 OIB dedup script, #4 scoreboard DELETE, #10 schema CHECKs
  cc5 → #2 /crm prefix sweep on crm.html, #3 trailing-slash sweep, #7 notif endpoint
  cc6 → #5 enrichment_worker batch on filled<4 klubovi

+**Generated:** 2026-05-05T06:25:39.772966Z
+**Backend routes:** 356
+**Frontend unique paths:** 54
+**Missing or misconfigured (frontend calls without correct backend):** 23
+
+## MISSING ROUTES
+
+### Routes with Trailing Slashes (6 issues)
+
+#### `GET /api/forms/`
+- Called from: `static/crm.html:L957`
+- Actual call: `api('/forms/' + code)`
+- Method: GET
+- Backend equivalent: `/api/crm/forms/{code_or_id}`
+- Fix: Remove trailing slash, add `/crm` prefix. Frontend should call `/crm/forms/{code}` (API base is `/sport/api/crm`)
+
+#### `GET|POST /api/forms/submissions/`
+- Called from: `static/crm.html:L1039`, `static/crm.html:L1087`, `static/crm.html:L1126`, `static/crm.html:L1135`, `static/crm.html:L1144`
+- Method: GET/POST (mixed)
+- Backend equivalent: `/api/crm/forms/submissions/{sid}`
+- Fix: Remove trailing slash when accessing specific submission by ID
+
+#### `POST /api/notifications/`
+- Called from: `static/crm.html:L1652`
+- Method: POST
+- Backend equivalent: `/api/crm/notifications/{nid}/read`
+- Fix: Remove trailing slash, use full path `/crm/notifications/{nid}/read`
+
+#### `GET /api/sportas/`
+- Called from: `static/sport2.html:L1582`, `static/sport2_new.html:L907`
+- Method: GET
+- Backend equivalent: `/api/sportas/{clan_id}/profil`
+- Fix: Remove trailing slash, include full path `/sportas/{clan_id}/profil`
+
+#### `POST /api/v2/enrich/`
+- Called from: `static/sport2.html:L376`
+- Actual call: `await apiPost('/v2/enrich/'+kind+'/'+id)`
+- Method: POST
+- Backend equivalent: `/api/v2/enrich/{kind}/{eid}/apply`
+- Fix: Append `/apply` to complete the route (e.g., `/v2/enrich/klub/{eid}/apply`)
+
+#### `POST /api/v2/forensic/findings/`
+- Called from: `static/sport2.html:L2873`
+- Actual call: `await apiPost('/v2/forensic/findings/'+findingId+'/enrich')`
+- Method: POST
+- Backend equivalent: `/api/v2/forensic/findings/{finding_id}/enrich`
+- Fix: Parameter name in backend is `finding_id`, ensure frontend passes correct ID
+
+### Routes Missing /crm Prefix (16 issues)
+
+#### `GET|POST /api/clanarine/`
+- Called from: `static/crm.html:L503`, `static/crm.html:L571`
+- Method: GET/POST (mixed)
+- Correct path: `/api/crm/clanarine` (no trailing slash)
+- Fix: Add `/crm` to path; frontend base is `/sport/api/crm` so call `/clanarine` instead of `/clanarine/`
+
+#### `POST /api/clanarine/bulk/notify`
+- Called from: `static/crm.html:L417`
+- Method: POST
+- Correct path: `/api/crm/clanarine/bulk/notify`

+- Fix: Update template variable in frontend to match backend parameter name, or update backend to accept `id` instead of `nid`
+
+## SUMMARY TABLE
+
+| Category | Count |
+|---|---:|
+| Total unique frontend paths checked | 54 |
+| Successfully matched to backend | 31 |
+| Missing routes with issues | 23 |
+| - Trailing slash issues | 6 |
+| - Missing /crm prefix | 16 |
+| - Parameter mismatches | 1 |
+| **Total call locations with problems** | **39** |
+
+## ROOT CAUSE ANALYSIS
+
+1. **Trailing slashes:** Frontend code constructs paths dynamically using template variables (e.g., `/api/forms/` + code), but leaves trailing slash in base path
+2. **Missing /crm prefix:** CRM module endpoints require `/crm/` prefix in API path, but some frontend files are calling the base `/api/` version instead of going through the CRM submodule
+3. **Parameter name mismatch:** Template variable names in frontend don't match backend parameter names (e.g., `{n.id}` vs `{nid}`)
+
+## RECOMMENDATIONS
+
+1. Audit all `api()`, `apiAuth()`, and `apiPost()` calls in frontend to ensure correct base paths and prefixes
+2. Review nginx rewrite rules to confirm `/sport/api/crm/*` → `/api/crm/*` mapping
+3. Add linting rule or static analysis to catch trailing slashes in API calls
+4. Document API path conventions for each HTML file (which use `/api`, `/sport/api`, `/sport/api/crm`, etc.)
+5. Consider normalizing frontend API call helpers to automatically handle path prefixes consistently

+# CC1 Consolidated Audit — 3 subagents
+**Generated:** 2026-05-05T08:30:00Z
+**Source reports:**
+- `_audit/audit_FRONTEND_COVERAGE.md` (SA-1, 9 files scanned, 0 issues)
+- `_audit/audit_API_GAP.md` (SA-2, 23 missing routes / 39 call sites)
+- `_audit/audit_DB_INTEGRITY.md` (SA-3, 48 dup-OIB clusters, 518 low-coverage klubovi)
+
+## Executive summary
+
+| Area | Verdict | Headline finding |
+|---|---|---|
+| Frontend coverage | **CLEAN** | 200+ onclick handlers, 9 forms, 8 modals, 28 tabs all wired correctly. No orphans. |
+| API gap | **NEEDS WORK** | 23 unique missing routes (39 call sites). Two systemic patterns: trailing slashes (6) and missing `/crm` prefix (16). |
+| DB integrity | **NEEDS WORK** | FKs/NULLs/audit-chain clean. 48 duplicate-OIB clusters in klubovi (~100 rows). 518/2244 klubovi (23%) have <33% coverage. |
+
+## TOP 10 critical (sorted by user-impact + fix-ease)
+
+### 1. Klubovi 48 duplicate-OIB clusters (DB)
+**Impact:** confuses joins, breaks unique business identity. **Fix:** run a `dedup_klubovi_by_oib.py --dry-run` then merge children (clanovi.klub_id, klub_sezona.klub_id, hns_klubovi_natjecanje.klub_id) onto the row with highest coverage and DELETE the duplicates. Then `CREATE UNIQUE INDEX CONCURRENTLY klubovi_oib_unique_valid ON klubovi(oib) WHERE oib ~ '^[0-9]{11}$'`. — owner: cc4 (DB)
+
+### 2. CRM frontend missing /crm prefix on 16 endpoints (API)
+**Impact:** crm.html buttons silently fail. **Fix:** in `static/crm.html`, change `api('/clanarine/...')` → `api('/crm/clanarine/...')` (and lijecnicki, forms, notifications, email-templates, zzjz). — owner: cc5 (CRM)
+
+### 3. CRM forms 5 trailing-slash 404s (API)
+**Impact:** form submissions fail. **Fix:** in `crm.html` L1039/1087/1126/1135/1144 strip trailing `/` from `/forms/submissions/${sid}` and `/forms/${code}`. — owner: cc5 (CRM)
+
+### 4. 14 scoreboard-string klubovi rows (DB)
+**Impact:** garbage in klubovi.naziv (e.g. `RK ... N. u II HRL Zapad od X` strings). **Fix:** `DELETE FROM pgz_sport.klubovi WHERE naziv ~ '\d+\. u (I{1,3}|IV) HRL .* od \d+'` (verify COUNT first). — owner: cc4 (DB)
+
+### 5. 518 klubovi <33% coverage (DB)
+**Impact:** worst panel UX, low-info entities. **Fix:** `python3 scripts/enrichment_worker.py --filter "filled<4" --limit 100 --concurrency 4` (existing CC6 module). — owner: cc6 (enrich)
+
+### 6. ~30 backup tables in pgz_sport schema (DB hygiene)
+**Impact:** ~97k rows of stale data, accidental queries against snapshots. **Fix:** `pg_dump --schema-only` snapshot then `DROP TABLE` each `*_backup_*`/`*_premerge_*`/`*_pre_*`/`*_dedup_*`. Move to `pgz_sport_archive` schema if cold storage preferred. — owner: cc1/dba
+
+### 7. /api/notifications/{nid}/read trailing slash (API)
+**Impact:** mark-as-read buttons fail. **Fix:** `crm.html:L1652` POST URL — strip trailing `/`, full path `/crm/notifications/{nid}/read`. — owner: cc5 (CRM)
+
+### 8. 3 [VERIFY]/[UNRESOLVED] klubovi (DB)
+**Impact:** placeholder names visible in UI. **Fix:** ids 2619, 2630, 4426 already flagged `metadata->>'manual_review'='true'`. Surface them in `/audit` UI for triage; or hard-link via Sportilus / sport-pgz manual lookup. — owner: cc1/cc6
+
+### 9. /api/sportas/{id}/profil — frontend trailing slash (API)
+**Impact:** sport2.html `openSportas` may 404 in some code paths. **Fix:** verify `static/sport2.html` doesn't construct URL with extra `/`; backend route is `/api/sportas/{id}/profil` (no trailing slash). — owner: cc1
+
+### 10. ALTER TABLE constraints to prevent regression (DB)
+**Impact:** prevents future garbage. **Fix:** add `CHECK (naziv = btrim(regexp_replace(naziv, '\s+', ' ', 'g')))` on klubovi/clanovi naziv columns; add unique index on klubovi.oib; document `sys_audit` retention (7d → 30d?). — owner: cc4
+
+## Owner allocation matrix
+
+| CC | Tasks |

+- Read full SA-3 detail: `_audit/audit_DB_INTEGRITY.md` (each query + result + fix SQL)
+
+## Methodology
+- SA-1 walked every `<button>`, `<form>`, `onclick=`, modal id, tab pattern across 9 HTML files. 0 orphans found — confirms the post-Round-3+ refactors landed cleanly.
+- SA-2 diff'd `openapi.json` (356 routes) against grep of `fetch|api|apiAuth|apiPost(...)` calls in static/. Normalised paths to FastAPI templates before matching.
+- SA-3 ran 8 read-only SQL probes (counts, NULLs, FKs, dup OIBs, placeholders, low-coverage, junk imports, audit health) — no DB writes performed.
+
+## What's already healthy (don't refactor)
+- ✅ Audit-chain (sys_audit row_hash + chain_idx) intact for all 100+ entries
+- ✅ FK integrity: no orphan klub_id / savez_id / user_id
+- ✅ Frontend onclick handlers all defined (post-R3 cleanup)
+- ✅ Mreža 3D graph centering on PGŽ savez (R6 verified)
+- ✅ JOSIP ZEC test case 257/182/15 still passing (verified earlier)

+**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 +

+    ) 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 |

+| 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;
+   -- repeat for klub_sezona, hns_klubovi_natjecanje, etc.
+   -- then DELETE the drop_ids from klubovi.
+   ```
+   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')));
+    ```

+## Coverage Summary
+
+**Frontend coverage is COMPLETE** — all onclick handlers, form submit handlers, modal close/open patterns, and tab switching mechanisms are properly implemented across all files.
+
+### Key Findings:
+- **Zero orphan handlers**: All 200+ onclick handlers reference defined functions
+- **Form handling**: 9 forms found, all have submit handlers (8 via onsubmit attribute, 1 via addEventListener)
+- **Modal management**: 8 modals properly handled via onclick event delegation or dedicated buttons
+- **Tab routing**: 28 tab elements across 4 files, all tabs have matching content divs and proper event listeners
+- **Shared sidebar**: All files load `/static/shared/sidebar.js` which provides global nav behavior
+
+### Architecture Notes:
+- **Modal patterns**:
+  - crm.html: Uses `id="modal-bg"` with `classList.add('open')` pattern
+  - erp.html: Uses `id="*Modal"` with `onclick="if(event.target===this)closeModal(...)"` pattern
+  - admin_users.html: Uses `id="*ModalBg"` with `class="show"` pattern
+  
+- **Tab patterns**:
+  - admin.html, admin_users.html, erp.html: Use `data-tab` + `#tab-*` with `querySelectorAll` binding
+  - crm.html: Uses `data-tab` + `#page-*` with custom setTab function
+  - sport2.html: Uses `switchKlubTab(element, tabId)` and `switchPlayerTab(element, tabId)` with inline element passing
+
+- **Form handling**:
+  - login.html: Uses addEventListener for form#loginForm submit
+  - app.html: Uses onsubmit attribute on form#prof-edit-form
+  - crm.html: Uses onsubmit attributes on dynamic form templates (created in modal)
+  - admin_users.html: Uses addEventListener for modal forms
+
+No refactoring needed.
