lukaszraczylo	75f7c18f3c	fix: hash drift, transformer leak guard, prod logger, ctx-aware wait ... M7: extractUnstructuredContent only hashed 'spec' when present, dropping all other top-level content fields. Resources with both spec and data (or any non-spec content) silently drifted until the next 10m resync. Now hashes every non-Kubernetes-managed top-level field, matching the fields updateUnstructuredMirror copies. M6: when a source has a transform annotation, also hash the source's labels and annotations (filtered of kubemirror.raczylo.com/* keys to avoid the controller's own bookkeeping churning the hash). Templates read these via TransformContext; without this a label change wouldn't re-render the transformed mirror. H3: text/template.Execute is not context-aware, so applyTemplateRule's timeout cancels the select but leaks the executor goroutine. Added a process-wide semaphore (cap 64) so a runaway template can't spawn an unbounded number of stuck goroutines on every reconcile. M4: zap dev mode (DPanic-on-error, console output, stacktraces on warning) was hardcoded on. Defaulted to production; --zap-devel flag remains for opt-in. M5: WaitForInitialDiscovery was anchored on context.Background() with its own WithTimeout, so SIGTERM during startup couldn't abort the wait. Now anchors on signalCtx.	2026-05-02 22:49:15 +01:00
