The ThirdParty/Libraries/Qt caches were never saved while the Telegram compile kept failing: actions/cache uses post-if:success(), so a failing compile skipped the save and every run rebuilt all libraries from scratch. Decouple cache save from the compile outcome: - restore@v5 + explicit save@v5 gated on steps.build-libs.outcome=='success' (saves run before the compile, never cache a half-built tree, survive a failing Telegram build), with continue-on-error so a benign duplicate-key save can't fail the job - keys become <scope>-<CACHE_VERSION>-<SDK>-<CACHE_KEY> with a tiered restore-keys fallback; CACHE_KEY hashes prepare.py recipes + win.bat (comment/whitespace churn no longer rotates the key) - CACHE_VERSION env is a manual kill-switch for non-auto-detected changes - self-healing "Verify restored caches" step deletes truncated/empty stage keys so prepare.py rebuilds them instead of trusting a corrupt restore - LTO ON only for nightly/tags (cheap link on dev retries); sccache gains idle-timeout=0 and an error log surfaced on failure Add cache-cleanup.yml: daily age-based prune of caches not accessed in N days, keeping the repo under the 10 GB budget without evicting hot caches.

# Keep the GitHub Actions cache under the 10 GB/repo budget so the LRU eviction
|
|
# never throws away a cache that is still in use. We prune by AGE: a cache not
|
|
# accessed in DAYS days is deleted. A restore bumps last-accessed, so any cache
|
|
# actively reused by any workflow family (win/linux/mac; libs/Qt/ThirdParty;
|
|
# sccache objects) always survives — only the genuinely stale tail is removed.
|
|
# (Rank-based "keep newest N" was rejected: it can strand the only cache of a
|
|
# low-frequency family and would churn sccache's many small entries.)
