check / check (push) Waiting to run
internal/log now logs through log/slog. After Init, records go to a small slog.Handler that prints the same lines as before; before Init they go to slog.Default(). The helpers and their call sites are unchanged. With NO_COLOR set on a terminal, log lines are no longer colored. pterm is dropped: it only printed progress lines, which fmt now writes directly, outside slog. apex/log, pterm and their indirect dependencies leave go.mod; golang.org/x/term becomes direct. simplelog is not imported: importing it replaces slog's default handler in every program that imports package mfer. The logger stays process-global, since injecting it would change package mfer's API. Progress and log lines now share the logger's lock, so the check progress test runs check ten times to catch a missing wait. Model: opus-5-5
