enricobuehlerandClaude Fable 5 9cda05dffb feat(ci): android gets a baked builder image; apple gets sccache and a pinned DerivedData
Android was the last job still downloading its world every run: ~3 GB of
SDK/NDK/CMake from Google, a from-source cargo-ndk build, and one monolithic
cache key where a gradle edit invalidated the cargo registry and the Rust
target/ with it. punktfunk-android-ci (content-keyed, LAN registry) bakes
JDK 21 + SDK + NDK + cargo-ndk + sccache; the workflow shrinks to checkout →
two caches → gradle. The cargo-home cache joins the fleet-wide namespace
(same lockfile, same layout — it was the same bytes under a private key),
gradle gets its own key shared with android-screenshots (which stored the
identical content under a second name), and target/ leaves the cache —
sccache covers the three ABI builds now.

Apple: sccache (self-healing ~/.local/bin install + already provisioned on
the mini) covers every cargo invocation build-xcframework.sh makes across
the swift job, the screenshots job and release.yml — three jobs that each
recompiled the same core. screenshots.sh learns PF_SHOT_DERIVED_DATA so CI
pins one stable DerivedData root instead of cold-building into two throwaway
mktemp trees per run (release.yml's disease, same cure), and the Simulators
get shut down after capture (the 846-leaked-sims lesson).

# Android client screenshots for the Play listing / marketing. Roborazzi renders the real Compose
# UI with mock state on the host JVM via Robolectric — NO emulator, GPU, KVM, host, or JNI core
# (`-PskipRustBuild` skips the cargo-ndk native build). The Android analogue of apple.yml's
# `screenshots` job, gated to STABLE RELEASE tags only. Standalone + best-effort: a failure here
# reds nothing else. PNGs land as a 30-day artifact; not committed or published.

# One pending run per workflow+ref: a newer push supersedes the queued/running one and cancels
# it (a canary only needs the latest commit; each release tag is its own ref so tag runs never
# cancel each other). Keeps a busy push cadence from piling ~10 queued runs per commit onto the
# runner fleet. Gitea honors this for push triggers (PR triggers: see gitea#35933).
