Done. HTML is **gitignored** (`reports/**/*.html`) by design — on-disk refresh is the deliverable, no commit needed. PKA wiki+data committed (691078b0); luci-autopush pushes next cycle.

## APPENDED 1 B4i email, 1 surcharge week

**PART 1 — B4i** (`Fuel-Prices-B4i.md`)
- New section `### 2026-06-08 (Mon)` — weekly, effective Tue 9/6, **increasing**: Shell CPT +16cpl, Astron +56cpl, Shell JHB inland +R1.00/L, Engen DUR 85cpl < Shell (supply from Sat 13/6), ZNZ new tariff 10/6.
- 2026-06-01 email already represented (last run). last_updated → 2026-06-09.

**PART 2 — Radixx** (`Fuel-Surcharge-Radixx.md` + `surcharge_history.{json,csv}`)
- 1 new file: `Fuel 2 June 2026.xlsx` → week **2026-06-02**, 26 routes.
- 19 May + 26 May = no surcharge file posted (pre-existing gap, naming changed `Fuel levy X`→`Fuel X`).
- Formula re-validated against stored 05-12 (0 mismatches): `final = round-half-up(ex_vat × 1.15)`, =ex_vat for *No Vat routes. +26 json/csv records, pivot column added.

**PART 3 — HTML** (`fuel-impact-2026-05-07.html`)
- `_MD_B64` re-encoded (23,928 chars → decodes to updated note incl. 2026-06-08 ✓).
- `_SURCH_PIVOT` rebuilt — 26/26 routes carry 02 Jun ✓. File 59,695→60,937 B.

⚠ **Data flag:** source file marks **CPT-PLZ as *No Vat** (R268 ex-VAT) — domestic route, unusual. Drop 458→268 is partly real fuel easing, partly the VAT-treatment switch. Reflected file faithfully; may be a Pieter spreadsheet quirk worth a check.

Suggested next: ping Pieter to confirm the CPT-PLZ *No Vat flag is intentional before the 02 Jun surcharge feeds any board/fare comms.

Want me to flag the CPT-PLZ VAT anomaly to Pieter? (yes/no)
