Operator ruling 2026-10-12 (S27, 09 §3 decision 222). The operator approves the Hungarian text before release. A box whose first ingestion failed now serves one bilingual waiting page and retries every minute instead of the wizard. Own commit so the lead can hold it back.

"""v0.126.0 mojibake gate — double-encoded UTF-8 can never enter the source again.
|
|
|
|
A bash-era in-place sweep once mangled Hungarian text by re-encoding already-encoded
|
|
UTF-8 (the "Tárhely"-class defect: á → á). Legitimate Hungarian UTF-8 NEVER decodes
|
|
to the signature characters below, so any hit is a defect. The allowlist is ZERO by
|
|
design — fix the text, don't allowlist it. (Windows grep false-negatives multibyte —
|
|
this gate is Python by the multibyte rule, like emoji_gate.)
|
|
|
|
Scans every template (web) and every Go source file:
|
|
- the file must decode as strict UTF-8 (undecodable bytes = broken already), and
|
|
- the decoded text must contain none of the double-encoding signature characters:
|
|
à (U+00C3)  (U+00C2) Ă (U+0102) ă (U+0103) ˘ (U+02D8) ˇ (U+02C7)
|
|
|
|
Run from controller/: python scripts/mojibake_gate.py
|
|
Exit 1 on any hit.
