* chore: retire the Everything Claude Code name, ECC only
Replace the expanded product name and the everything-claude-code slug
with ECC across READMEs, translated docs, harness folders, skills,
commands, scripts and examples. Repo URLs now point at affaan-m/ECC.
Rename repo-internal artifacts to ecc forms (ecc-conventions skill,
ecc-guardrails, ecc-research-playbook, ecc-team-config, ecc-instincts
with ecc-* ids) and update .claude/ecc-tools.json.
Legacy install ids, plugin dirs, package names and MCP prefixes stay
where existing installs resolve against them. The codex global-state
check and harness-audit repo detection accept the new name first and
the legacy one as a fallback. The Discord bot prefers ~/GitHub/ECC and
falls back to the nested legacy checkout path.
Refresh the skill-triggers registryDigest for the changed skill text.
* fix(ecc-tools): drop managed paths to the removed Claude repo skill
.claude/skills/<repo-skill>/SKILL.md was deleted in #2770 but stayed listed in
ecc-tools.json and the team config. Remove those entries and point the Claude
Code adapter at the existing .agents/skills/ecc-conventions/SKILL.md.
* fix: disable Claude co-author attribution by default
* fix: harden default co-author opt-out and correct the docs
Follow-up on the co-author default in this PR.
- Remove the existsSync/writeFileSync race in the installer settings write
(CodeQL js/file-system-race, high). A single guarded read now covers the
fresh-install case, and unreadable or non-object settings are left untouched.
- Respect `attribution` as an explicit user choice. It supersedes
`includeCoAuthoredBy` in Claude Code 2.1.x, so a user who configured it would
otherwise have had a dead key written into their settings.
- Share one opt-out rule via scripts/lib/claude-commit-attribution.js instead of
duplicating it across the installer and plugin setup.
- Update the git-workflow rule and its nine mirrors and translations, which
still told users ECC does not ship this setting.
We keep writing the deprecated `includeCoAuthoredBy` key rather than
`attribution`: unknown keys fail Claude Code settings validation, so writing
`attribution` would break users on older versions.
