[no-release] fix(bridge-node): tolerate matter.js's re-init window after a last-fabric unpair (#133)

[simons-plugins]

Closes #133.

What

Unpairing the last fabric makes matter.js factory-reset itself; for ~200ms getPairing()'s reads throw UninitializedDependencyError, and the plugin's post-unpair re-read — confirming a successful unpair — logged Command get_pairing failed: … is not initialized (observed live 2026-08-06; the node was advertising again 200ms later).

How

settlePairingRead() — a bounded retry the ws-server's get_pairing handler now goes through (getPairingSettled on the BridgeFacade seam; ws-server deliberately imports no matter.js types). Node-side, so every caller benefits: the plugin's fabric-cache refresh, the menu, the IWS QR page.

• Detection is instanceof UninitializedDependencyError against the real matter.js class (re-exported by @matter/main — verified in 0.17.8's source), no message-text matching.
• Any other error rethrows immediately, no retry, no delay.
• Deadline 3s (15× the observed window; comfortably under the client's 10s wire timeout, so a genuinely broken node still fails on our deadline carrying the real error), 75ms interval, unref'd timer.
• Past the deadline the last error rethrows unchanged — today's failure frame, just later.
• Sync getPairing() untouched for internal callers. No wire change, no Python change.

Tests

5 new (404 TS total; 2265 Python untouched): retry-then-succeed / same-error-past-deadline / non-transient-no-retry-no-delay / first-success-no-sleep — all against an injected fake clock, so they run instantly — plus a handler-wiring test that fails if get_pairing bypasses the settled path (mutation-verified by reverting the wiring).

Note: this is node source after the unpublished 0.8.0 bump, so it rides along whenever indigo-matter-bridge@0.8.0 is published — no extra publish step created.

Version 2026.8.10 → 2026.8.11.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
