Testing / test (push) Failing after 10m21s
- compat.py → compat/ package: auth.py (auth-field normalizers), commands.py (command-format shims), __init__.py (re-exports) - Add _auth_0_9_3 transformer: normalizes pubkey to lowercase before auth so clients < 0.9.3 sending uppercase hex are accepted - adapt_auth() now called before auth check in serve.py; command extracted after adapt_auth so future transformers can rename commands safely - serve.py: deduplicate _recv_exact (import from client), unify resp/resp_payload across Windows/Unix branches, require lowercase hex pubkey (re.fullmatch), reorganize imports, drop unused os import - client.py: move payload/framed construction inside branches (remote path no longer serializes JSON it never uses); fix _is_valid_key_spec operator precedence; import MAX_MSG_BYTES from version_manager - auth.py: narrow except clause (ValueError instead of bare Exception) - Bump version 0.9.2 → 0.9.3 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Command-format shims — applied to clean_msg (protocol fields already stripped)
|
|
before forwarding to the native host, and to responses before sending back.
|
|
|
|
Add one entry per breaking command-format change:
|
|
("X.Y.Z", request_fn, response_fn)
|
|
|
|
- request_fn(msg: dict) -> dict or None
|
|
- response_fn(resp: bytes, command: str) -> bytes or None
|
|
|
|
Entries must stay in ascending version order.
|
|
adapt_request walks forward (oldest first); adapt_response walks backward.
|
|
|
|
Current baseline: 0.9.3 — no command-format shims needed yet.
