Greptile Summary

This change adds Python-authored browser channels and codec registration, generates relay bridge ports for those declarations, and delivers encoded custom streams through lazy browser subscriptions.

The custom path flow was exercised with a real local relay and Chromium browser: the page connected and rendered all three delivered points. Focused coverage also passed for generated-port routing, subscription-gated encoding, codec parameter isolation, cache replay, encoder-failure isolation, parameter validation, dynamic class deployment, and blueprint pickling.

T-Rex validation blocked

• Tool: the prescribed SDK test command could not execute because ensure_deno() wrote an informational message to standard output, contaminating the captured Deno binary path and causing exit 127. The browser and Python relay validations completed successfully.

Confidence Score: 5/5

The exercised custom-channel authoring and browser-delivery flow is safe to merge.

No defects remain in the review output. A real browser session verified delivery through the local relay, and 216 focused runtime tests covered the main routing, serialization, lazy-subscription, and isolation behaviors.

Files Needing Attention: No files require corrective changes. The SDK test invocation in the setup guidance merits follow-up because resolver logging prevents the documented command from locating the Deno binary.

T-Rex Logs

What T-Rex did

• T-Rex completed the requested contract verification, noting that local artifact references were not uploaded.
• A browser and runtime verification sweep was performed, covering the browser-session assertion (points: 3, coordinates 1.5 and -2.5, connected) and a suite of runtime tests including generated-port lazy encode routing, no encode before subscription, subscription toggling, independent JPEG qualities, cache replay, encoder-failure isolation, parameter validation, dynamic class deployment, and blueprint pickling.
