 29	2ff0cb8	63	0.0	keep	pass	CORDIS contracts purity: gate check 2.2 forbids TableName()/gorm tags in core/contracts + removed UserDTO.TableName(); upload/handler test now seeds via explicit .Table("w_users") (precedent: filesrv test). Proven twice over: gate named auth.go:33 pre-fix, and iter-28 revert broke 1 package without the test fix. Delta-0 keep under the agreed real-defect gate
 30	9ea0e2b	63	0.0	keep	pass	SECURITY (assertion-proven): FindUserByFieldRecord interpolated its column arg into WHERE with only a prose comment as guard. Pre-fix the tautology "username = '' OR 1=1 --" EXECUTED and returned a row with err=<nil> (filter bypass). Now an allow-list rejects before GetDB. Also first test in the repository pkg: tests_passed 47->48, funcs 282
 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
