- Around line 1039-1053: Update the config preflight around configPath and
hasConfig to use lstat for both config.yaml and config.yml, rejecting either
path when it is a symbolic link before setup proceeds. Create the missing config
with exclusive or no-follow semantics so a replacement symlink cannot be
followed after preflight.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
Reject symbolic-link config paths before writing.
existsSync() returns false for a dangling openspec/config.yaml symbolic link. The current flow then accepts the writable parent directory, and writeFile() follows the link. This can write outside openspec/ and makes the dangling-link regression test fail.
Use lstat for both config.yaml and config.yml. Reject symbolic links before setup starts. Use exclusive or no-follow creation semantics when writing the new config to prevent a replacement race after preflight.

Risk: low. Opt-in flag. Default
initoutput is byte-for-byte unchanged.What was missing
OpenSpec supports non-English artifacts through project context, but new projects had to hand-edit
openspec/config.yaml. #1049 asked for a non-interactive option.What changes
Adds
openspec init --language <language>, which writes language guidance into the config — but only when creating a new one.Why it's safe
.yaml/.ymlconfigs and external-store pointers are never modified.SHALL/MUSTkeywords stay in English, so generated artifacts still validate.Proof
197 focused unit, config, completion, external-store and packaged-CLI tests. A packaged end-to-end test proves the language context actually reaches resolved artifact instructions. Boundary tests cover exactly 50KB accepted and one byte more rejected.
Closes #1049
