v1.0.0 — Stable contracts

The first stable release.
Nothing new to learn — this release is a promise about what will not change.

A compatibility guarantee

The surfaces you build against are now stable under semantic versioning:

• the command-line modes and flags
• the .semlf.ini settings
• the --json document format
• the suppression directives
• the exit codes
• the GitHub Action's inputs and outputs
• the names you install by — the semlf package and command, the pre-commit hook id, the Claude plugin name

all on Python 3.9 or newer.
A change that would break any of them now costs a major version;
new capability arrives in minor versions.

Two things deliberately stay flexible:
which lines draw findings (precision keeps improving between majors),
and the wording of messages — the text is for people, the structure is for tools.

Every exit code, documented in one place

The README now carries a mode-by-mode table of what 0, 1, 2, and 64 mean,
including the two deliberate choices in it:
a hook exits 0 on a payload it cannot read,
because a hook must not block your editing on its own malfunction,
and render exits 0 however many findings it renders,
because what a finding means for a build is the gate's decision.

Changed

• The Action's fail-on input says exactly what it accepts.
  It always took a comma-separated list of fused and wrap in either order,
  with duplicates and stray whitespace tolerated;
  now its description and error message say so, and tests hold them to it.

Fixed

• The detector reference caught up with the checker.
  The specification now documents the option that names why a suggestion was withheld,
  and the field it adds when asked.

Install

uv tool install semlf        # or: pipx install semlf / pip install semlf
semlf install                # wire up the agents you use
