Detailed Description

U2 (2026-09-07) — [INITIAL_QUALITY] rows for MSX species.

[INITIAL_QUALITY] is the canonical home of a per-element initial value for ANY constituent — pollutant, reactions-component species, age, temperature. The reactions engines (LEGACY binding, ARD, LARD) seed MSX species from ReactionData::init_elem_*, the table [REACTION_QUALITY] NODE|LINK fills. This helper mirrors the MSX-kind rows of ctx.initial_quality into that table so every engine sees them without a fourth seed site:

• called from PostParseResolver after the rows are classified,
• called again by the reactions component whenever it re-parses its [REACTION_QUALITY] block (the block reset clears the table; the mirrored rows must come back).

A row the .rxn also carries (same element, same species) is an error — the same duplicate policy [INITIAL_QUALITY] applies to itself. The ReactionsWriter skips mirrored rows so a save emits each row once, in [INITIAL_QUALITY].
