LDC-E5209 — Ambiguous source text hash

One source content_hash cannot identify several text items. With two or more texts, the compiler refuses the source form even if bytes coincide. Keep one source text for this hash, use separate editions/fragments, or provide direct CLIR with an individual texts[i].contentHash for each text. The compiler does not choose an official text or concatenate texts. No E5201 hash-replacement quick fix is offered for this ambiguity (§28).
