Jon Chery	0358efe95b	fix(P07): concurrency safety — SQLite, flock, cache, atomic writes (REQ-156) ... - SQLite busy_timeout(5000) + SetMaxOpenConns(1) on all 4 DSNs - secrets file flock (concurrent set on same ns no longer loses data) - upgrade lock file (refuse concurrent orca upgrade) - backup lock file (refuse concurrent backup) - cache invalidation by writes (read-after-write consistency) - Executor.Run mutex scope fix (hold only for DB inserts) - ns create/inherit/set-constraint atomic writeNSMdAtomic - writeCurrentLead + rotateSSHKeys atomic - consolidate 3 writeAtomic impls onto security.WriteAtomic - WebAuthn session stores guarded with sync.Mutex Tests: concurrent secrets set, upgrade lock rejection, cache read-after-write, WebAuthn session thread-safety (pass under -race). ---ci--- project: orca phase: 7 milestone: v0.13 status: complete requirements: covered: [156] ---/ci---	2026-08-10 12:27:05 +00:00
