0.1.2 fixes what the first production Signage deployment found: - #4: the display and server share one message schema; every heartbeat from an image slide used to be refused with a 400; - #5: every display request retries with backoff and never gives up, so a display that failed one request no longer stays offline until reloaded; - #6: one object URL per cached slide, released when done; the leak exhausted the browser within minutes; - CI (#7, #8): every change runs inside a pinned Ekklesia, end to end in a real browser, and cleans up even when killed. compatibility.platform stays ^0.1.0: every fix is module-side, and CI tested it against platform v0.1.1 plus test-only scripts. The README no longer says Signage is unreleased or undeployed. Co-Authored-By: Claude Opus 5.5 <[email protected]>
