- Add SSH-style server identity keys and known-host verification for remote serve endpoints. - Add remote add/list/remove commands for explicit endpoint persistence. - Fix remote clients listing to fan out through target discovery instead of ambiguous auto-routing. - Add URL glob matching for tabs filter and count with extension tests. - Add n8n credential pinning for server public keys or SHA256 fingerprints. - Remove obsolete compat shim behavior while keeping empty compat seams for future protocol changes. - Bump browser-cli to 0.16.4 and n8n node to 0.3.1. - Cover known-hosts, remote registry, compat seams, n8n protocol verification, and URL matching with tests.

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.
|
|
|
|
The registry is intentionally empty: no command-format shim has been needed
|
|
since the first public release (0.14.1). This module is the seam — add a tuple
|
|
here (and a unit test for it) the day a breaking command-format change ships.
