Benjamin Admin c2c8783fee refactor(agent-check): split routes file (2692→347 LOC) + wire B1/B3/A1 [guardrail-change]
Phase-5 split of agent_compliance_check_routes.py — the 2700-line
monolith was decomposed into 19 modules in compliance/api/agent_check/:

  - Phase A-F: resolve / profile+check / banner+TCF / vendors raw+finalize /
    HTML blocks top+mid+bot / email / persist
  - Helpers: _constants, _helpers, _fetch, _discovery, _single_check
  - Schemas + State + thin _orchestrator

A1 ZIP-Anhang nativ in _phase_e_email: evidence_zip_builder.py bundles
slices + manifest.json + audit_metadata.json (SHA256 per slice +
build_sha + source_url). smtp_sender.py erweitert um attachments-Parameter.

B1 COOKIE-CONSENT-UX-001 (Mobile Reachability): consent_reachability_check.py
parses footer anchors, classifies intent (reopen_cmp / info_only /
browser_deflect) + target (same_page_cmp / new_tab / external).
_b1_wiring.py fetches homepage with iPhone-UA + renders Art-7-Abs-3
severity-coloured block.

B3 TH-RETENTION (Cross-Doc Speicherdauer): retention_comparator.py
compares DSI claim ↔ cookie-table duration ↔ actual Max-Age/expires
with 5% tolerance + severity hierarchy (dsi_under_actual HIGH,
table_under_actual HIGH, dsi_vs_table MEDIUM, actual_under_table LOW
Safari-ITP-Hint). _b3_wiring.py + Top-10 mismatches table in mail.

Side-effects:
- Fixed silent UnboundLocalError in original Step 5 (gf_one_pager used
  audit_quality_findings before declaration, caught by surrounding
  except → block never rendered). New _phase_d3_blocks_bot.py runs
  audit-quality FIRST.
- agent_compliance_check_routes.py removed from loc-exceptions.txt
  ("Phase 5 split target" — done).

Tests: 55/55 grün (B1 22 + B3 27 + saving_scan 6).
E2E: smoke against Elli DSE+Cookie produced HIGH/missing B1 finding,
TH-RETENTION table (17 cookies / 3 ✓ / 3 ✗ / 11 ?), evidence-zip
with 2 slices + manifest + audit_metadata (12089B, SHA256-chained,
source verified), email sent (attachments=1).
