 31	5193bd0	63	0.0	keep	pass	HARNESS INTEGRITY: measure.sh and checks.sh now key GOLANGCI_LINT_CACHE per checkout. The default cache is machine-wide, so entries written by a sibling worktree replayed here carrying ITS absolute paths (12 of 63 lines pointed at an outside checkout), misattributing findings and risking a stale Guard verdict. Proven count-neutral: cold and warm both 63; foreign paths now 0. Delta 0 by design, kept under the agreed real-defect gate
 32	f7a86d3	63	0.0	keep	pass	PERF+DEDUP: three packages hand-rolled mutex+[]string+MatchPathPattern loop, re-normalising and re-splitting immutable patterns per request. New extpoints.PathWhitelist compiles patterns at registration and absorbs all three. Mechanically asserted: 14 allocs/op -> 1 allocs/op; equivalence test pins Match against the legacy loop over a full pattern x path matrix; race-clean. funcs 282->288, coverage 35.02
 33	99fca9e	62	-1.0	keep	pass	BUGFIX+DEDUP: task.loadActiveStorageConfig and saveActiveStorageConfig duplicated uploadstorage.LoadStorageConfig/SaveActiveConfig but swallowed all three failures (nil db, read error, json parse) returning zero config + nil error, making the caller-s already-written error branch dead: a storage migration could run from an unknown active driver. Now routed through the canonical accessors; regression test corrupts the stored config and asserts Execute errors (assertion-proven via revert). funcs 289
+34	b22f863	62	0.0	keep	pass	BUGFIX+PERF: LoadSMTPConfigRecord fired four single-key queries and discarded every error with underscore assignment, so an unreadable w_system_configs returned four blank strings both callers could only read as "SMTP not configured" -> notification silently dropped. Now one IN query plus a real error channel; callers log at the boundary and keep their own values. Proof is signature-level and exact: the old API had no error return, so the failure was unrepresentable. 4 queries -> 1, funcs 291
