fn paths_for_provider(provider_id: &str, working_dir: &Path) -> Vec<String>Expand description
Every path this provider reads, plus AgentMux’s own side file.
.claude/AGENTMUX_MEMORY.md is included for providers whose write target
is CLAUDE.md, because that is the file AgentMux falls back to when the
repository owns CLAUDE.md
(SPEC_CLAUDE_MD_OWNERSHIP_PROTECTION_2026_08_22.md) — it is genuinely
read, via an @-import line, and an instruction set that omitted it would
be missing AgentMux’s own contribution. It is not in the registry’s
native_instruction_sources because the provider does not discover it
natively; the import line is ours.
