ADR0017V01R01 — ANSI style model: color only (no attributes)

Context

The ANSI interpreter used by the test driver must model the styling that production code actually emits, no more and no less. The question was whether to model text attributes (bold, underline, etc.) in the style grid.

Decision

Model color only (foreground / background), no text attributes. Verified in code:

• Style (ConsolePlus/src/Shared/Style.cs:23-38) exposes only Foreground, Background and OverflowStrategy.
• ConsoleWriter.ApplyStyle (ConsoleAbstractions/ConsoleWriter.cs:257-268) emits only SGR sequences from AnsiColorBuilder (color).

Production does not emit bold/underline/etc today, so there is nothing to model in the grid. The // TODO Fase 2: 4-bit / 256 comments in the source are confirmed as “not applicable”, not as pending work.

Consequences

• Positive: the interpreter stays small and matches real output exactly; snapshots are simpler.
• Negative / trade-off: if production later emits attributes, the interpreter and this decision must be revisited (a new version of this ADR).
