internal/log now logs through log/slog. After Init, records go to a small
slog.Handler that prints the same lines as before, colored by the same
rule; before Init they go to slog.Default(). Level filtering, the helpers
and their call sites are unchanged. With NO_COLOR set on a terminal, log
lines are no longer colored.
pterm is dropped: mfer used it only to print progress lines to the
configured stdout, which fmt now does directly, outside slog. apex/log,
pterm and their indirect dependencies leave go.mod; golang.org/x/term,
already in the module graph, becomes direct.
simplelog is not imported: importing it replaces slog's default handler,
in every program that imports package mfer, with one that writes to
stdout. The logger stays process-global, since injecting it would change
package mfer's API.
Model: opus-5-5
Adopts golangci-lint v2.12.2 and the canonical .golangci.yml (default: all), and fixes all resulting findings across the tree.
Two intended behavior changes: absent MFFilePath.Mtime is handled explicitly in freshen, list and export rather than dereferenced (main panicked); gpg positional key IDs now follow an explicit -- end-of-options marker.
All twelve reworded user-visible error messages restored to byte-identical parity with main and pinned by tests.
