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.
